Did you rerun `npm install` after `npm install -g composer-cli`?

yes

sstone1 (Thu, 09 Feb 2017 21:18:05 GMT):
It doesn't look like worked, there's no chaincode container showing up in the output of `docker ps`

pards (Thu, 09 Feb 2017 21:18:56 GMT):
There are only two containers defined in the docker-compose.yml

sstone1 (Thu, 09 Feb 2017 21:19:17 GMT):
`npm install` should run `composer network deploy` which deploys a new chaincode instance to the fabric instance

We might have to boot you out of here

sstone1 (Thu, 09 Feb 2017 21:35:09 GMT):
Anyway - pards - is it possible that you had node-gyp errors when running `npm install` in the getting-started directory?

pards (Thu, 09 Feb 2017 21:35:27 GMT):
Yes. node-gyp was a PITA

sstone1 (Thu, 09 Feb 2017 21:35:55 GMT):
you could try a `git clean -xdf` in the getting-started directory which will wipe out the node_modules folder, followed by another `npm install`

pards (Thu, 09 Feb 2017 21:36:12 GMT):
sure

dselman (Thu, 09 Feb 2017 21:38:41 GMT):

sstone1 (Thu, 09 Feb 2017 21:40:55 GMT):
Awesome, no problem

sstone1 (Thu, 09 Feb 2017 21:41:21 GMT):
Was there anything you did (extra packages?) to fix the node-gyp issues or just the reboot? Just wondering if we can update the docs.

dselman (Thu, 09 Feb 2017 21:41:38 GMT):
Did you do `sudo apt-get -y install build-essential libssl-dev` ?

pards (Thu, 09 Feb 2017 21:42:10 GMT):
To be honest, I tried a bunch of things and don't recall exactly what fixed the problem

pards (Thu, 09 Feb 2017 21:42:20 GMT):
I think I installed node-gyp separately

pards (Thu, 09 Feb 2017 21:43:15 GMT):
... or `npm install hashtable@2.0.2`

pards (Thu, 09 Feb 2017 21:44:00 GMT):
I might ice this VM and try a fresh install to figure out the steps more precisely

Hi, in the composer modeling language, how mappings are expressed? I see support for Arrays but didn't see a way to add a mapping as a field member of an Asset. Anybody can enlighten?

jdockter (Fri, 10 Feb 2017 14:33:16 GMT):
Not sure if this helps but here is the doc on the CTO modeling language which has examples on Arrays, specifically the asset Field and its relationship to Animals, https://fabric-composer.github.io/reference/cto_language.html

ayoub (Fri, 10 Feb 2017 15:48:22 GMT):
thanks @jdockter for the reply. Actually what I am looking for is more for a map/dictionary e.g if in an asset I need a field that contains a mapping of which cannot be represented in Arrays, are there any other ways to achieve this sort of mapping?

jdockter (Fri, 10 Feb 2017 16:25:51 GMT):
I'm not aware of map support... @dselman or @sstone1 can you comment?

sstone1 (Fri, 10 Feb 2017 16:27:12 GMT):
@Ayoub Naciri we do not have support for mappings at the moment

ayoub (Fri, 10 Feb 2017 16:34:35 GMT):
thanks @sstone1. are there any plans to support mapping in the near future?

So ... the root cause of my installation issues with `node-gyp` was the self-signed certificate in the chain

pards (Fri, 10 Feb 2017 20:56:53 GMT):
`node-gyp` doesn't honour the `strict-ssl=false` setting in `.npmrc`

pards (Fri, 10 Feb 2017 20:57:16 GMT):
The workaround to get composer-cli to install was to run the following:

pards (Fri, 10 Feb 2017 20:57:45 GMT):
```export NODE_TLS_REJECT_UNAUTHORIZED=0

pards (Fri, 10 Feb 2017 20:57:48 GMT):

pards (Fri, 10 Feb 2017 20:57:59 GMT):
```NODE_TLS_REJECT_UNAUTHORIZED=0```

pards (Fri, 10 Feb 2017 20:57:59 GMT):

@dselman I was looking at the next iteration plans- how far will you get with: Port to HL v1.0, working in a branch until we feel like the time is right to flip all development to HL v1.0. We will attempt to minimize the distruption on the team and the length of time that we have to support both the v0.6 and v1.0 branches.

dselman (Mon, 13 Feb 2017 21:07:22 GMT):
@weeds that largely depends on the stability of Fabric and the changes in behavior that we discover and have to workaround. For example, the changes related to not being able to Read-Your-Own-Writes (local consistency guarantees for key write/read).

I just noticed that when I create a PR into fabric-composer from my fork, after a build has run against my fork triggered by a `git push` that I get a 'merge build' running on my local fork too. I think that this is pretty pointless and so have disabled this by clicking the 'cog' icon in Travis next to my fork to open up the settings and then turning off the 'Build pull requests' option for the fork. Hopefully this will stop the merge builds running on my fork :)

There's a few outstanding items though. 1) Read Your own Writes has disappeared between 0.6 to 1.0, so we have to make some changes to accommodate that 2) we need to accommodate the recent deploy changes (it's now install + instantiate) and 3) we need some SDK functionality before we can implement issuing/revoking identities

@sstone1 hopefully you will keep channel updated with progress. Sounds good so far.

tarima (Thu, 16 Feb 2017 18:21:49 GMT):
@mbwhite @dselman Thank you my comment. The parameters of “enrollId” and “enrollSecret” for “composer participant add” only add participant without Membership Service of fabric. so now, enrollId should add membership for fabric before right?

sstone1 (Thu, 16 Feb 2017 21:34:19 GMT):
@tarima participants and identities are separate concepts in Fabric Composer. A *participant* and their details (name, address, etc.) is recorded in a participant registry. A participant is then issued with *identities* (ECerts/enrollment IDs) that they can use to interact with the business network.

sstone1 (Thu, 16 Feb 2017 21:34:58 GMT):
You need to `composer participant add` to add the participant to a participant registry, and then `composer identity issue` to issue that participant with an ECert (enrollment ID + generated enrollment secret)

I followed the instructions on installing the fabric composer playground UI using the docker image here, https://fabric-composer.github.io/start/getting-started-playground.html, and now I want to connect to an existing business network running on my localhost. Two questions...1) what value do I enter for Key value store directory on the connection profile? and 2) when prompted for adding an identity what is that actually doing under the covers?

jdockter (Fri, 17 Feb 2017 15:39:56 GMT):

@tarima you need to add single quotes around the JSON on the command line, so try `composer participant add —p defaultProfile -n digitalproperty-network --enrollId WebAppAdmin --enrollSecret DJY27pEnl16d -d '{"$class":"net.biz.digitalPropertyNetwork.Person","personId”:”user1@example.com”,”firstName":"Mae","lastName":"Smith"}'`

Removed all my existing containers and used the docker-compose file to spin up membersrvc, peer and composer-ui containers. Seems that the playground docker container has it's own set of credentials, so the pre-configured connection profile of 'hlfabric' is setup to use '/home/composer/.composer-credentials' which is apart of the composer-ui container. For some reason I couldn't couldn't docker exec -it into the container to confirm. Please let me know if I have that correct, thanks.

sstone1 (Fri, 17 Feb 2017 21:14:10 GMT):
@jdockter you're correct, the credentials are stored within the composer-ui container when using the Docker images.

sstone1 (Fri, 17 Feb 2017 21:14:37 GMT):
If you install using npm (`npm install -g composer-ui; composer-ui`) then the credentials are stored on your file system.

ah nice...thanks @sstone1

We just moved our experimental syntax highlighter for Atom into Open Source. It is here and includes install instructions: https://github.com/fabric-composer/tools/tree/master/composer-atom-develop We welcome contributions to make this more useful. We are also working on publishing a more full-featured VSCode plugin which should be available shortly.

# Proposal for Fabric Composer Playback 3 ### Target Date: March 10th ### [Issues](https://github.com/fabric-composer/fabric-composer/milestone/10) ## Project Governance We are actively soliciting interested individuals, organization and companies to contribute to Fabric Composer development. The existing team will reach out to the HL community for feedback on how best to organize transparent and open weekly planning meetings, scrum calls, chat, mailing lists, playbacks, design/architecture sessions etc. ## Composer Playground IBM will contribute low-fi and hi-fi design screens for a next generation of the Composer Playground web user interface. Links to the design screen will be attached to the GitHub issues ASAP. The team will build a new Playground web application, based on Angular2. The new Playground will be created in the composer-playground npm package (as a peer of the existing composer-ui package). The docker image will be called composer-playground and published to DockerHub. Eventually the new composer-playground npm package and docker image will supersede the old composer-ui packages and these will be frozen/retired and eventually removed. Composer Playground will be deployed to IBM Bluemix as an experimental free and public service to gather feedback from users. The version on IBM Bluemix will initially *only* support the Web Connection Profile (simulating Hyperledger Fabric in the browser). The community is encouraged to run the Playground in other environments, and connecting it to HLF, using the DockerHub image and providing feedback. ## Loopback and REST APIs The team will continue to enhance the existing Loopback support, improving ease-of-use, supporting servers with multiple business networks deployed, adding the ability to submit transactions and to define authentication/authorization for the REST API. ## Support for Hyperledger Fabric v1 The team has already started to process of testing and porting to Hyperledger V1 and is making good progress. The working assumption is that the team will add support for a new Connection Profile type (hlf-v1) and that the runtime will seamlessly support business network definitions on a v1 HLF. There will likely to changes to the start/download scripts and deploy/undeploy commands based on the operational changes in HLF v1. The team will assess the best moment to switch default support from v0.6 to v1 (and when to drop support for v0.6) based on progress over the coming weeks. ## Samples The team will publich a new Angular2 end-to-end sample based on DEFRA requirements for tracking animals as they move between farms. ## Community Outreach The team will attend the HL Meet-up in London on March 2nd. We encourage the community to blog/vlog about their experiences using Fabric Composer, engage on the HL RocketChat #fabric-composer channel, answer/ask questions on StackOverflow using the fabric-composer tag, and tweet using the #FabricComposer hashtag.

paul.sitoh (Tue, 21 Feb 2017 10:42:15 GMT):
Folks, yesterday someone asked me if composer also included cello (fabric orchestrator). He said that composer had a feature to create business network. Does that mean it is also able to spin up a fabric network -- i.e. create nodes, ordering service (v1), etc and string everything together so to speak? If yes does it use cello?

dselman (Tue, 21 Feb 2017 10:52:46 GMT):
No, Composer does not provision the Fabric -- it just deploys a business network DEFINITION to it. The BND is a logical description of the structure and behavior of a business network, not the physical infrastructure.

dselman (Tue, 21 Feb 2017 10:53:37 GMT):
I'm guessing you can use Cello to stand up the physical Fabric and then use Composer to model your business network definition and deploy to the Fabric.

@VipinB Composer manages participants and identities. Participants represent the people/orgs that are members of a business network. They are modelled and can be complex data structures, with relationships to other assets or participants. An identity is issued/revoked for a participant, and the identity <--> participant mapping is stored in world state by Composer. A single participant may have multiple identities. An identity is related to a single participant. The identity is stored in an ECert as an encrypted attribute, so that when a transaction is submitted Composer can retrieve the identity and through the identity-participant mapping table retrieve the associated participant. Docs: https://fabric-composer.github.io/tasks/identity-issue.html https://fabric-composer.github.io/tasks/identity-revoke.html . The current participant is the basis for access control: https://fabric-composer.github.io/tasks/current-participant.html

dselman (Wed, 22 Feb 2017 07:36:33 GMT):
The CLI also includes commands to manage participants/identities: https://fabric-composer.github.io/reference/commands.html

dselman (Wed, 22 Feb 2017 07:37:45 GMT):
@anzalbeg all Fabric Composer state (including the business network definition itself) is stored on the blockchain in world-state, using the typical getState/putState APIs.

Have you run Playground before with this web browser?

omkardash (Wed, 22 Feb 2017 10:10:12 GMT):
Yes..

dselman (Wed, 22 Feb 2017 10:11:06 GMT):
What browser are you using? Can you try clearing the cache / local storage?

omkardash (Wed, 22 Feb 2017 10:11:10 GMT):
Chrome

omkardash (Wed, 22 Feb 2017 10:11:17 GMT):
I will clear it, and let you know

omkardash (Wed, 22 Feb 2017 10:11:34 GMT):
I should have tried that as step 0, I guess

omkardash (Wed, 22 Feb 2017 10:20:13 GMT):
@dselman Done,

omkardash (Wed, 22 Feb 2017 10:20:21 GMT):
but that did not solve the issue

dselman (Wed, 22 Feb 2017 10:21:09 GMT):
So when you go to http://localhost:8080 it tries to connect to Hyperledger instantly? You don't do anything in the UI?

dselman (Wed, 22 Feb 2017 10:23:46 GMT):
Ok, that means you have a cookie or something set in your browser localstorage for localhost:8080. On a first visit it should use the web profile.

dselman (Wed, 22 Feb 2017 10:23:59 GMT):

dselman (Wed, 22 Feb 2017 10:31:01 GMT):
We need to fix the problem of caching credentials for HL in the browser. If you restart HL then those credentials don't work anymore and you need to flush localStorage and cookies to clear.

omkardash (Wed, 22 Feb 2017 10:32:53 GMT):
Yes, that'd be nice. For someone who is exploring, it might get a little tricky.

Hi! I'm having trouble installing `composer-cli` on Mac OS El Capitan 10.11.6, running into linkage issue to hashtable which apparently is a known problem (see https://github.com/chad3814/node-hashtable/pull/31). Are others having a similar problem? Scrolling up in the chat doesn't seem to suggest as much.

dselman (Wed, 22 Feb 2017 22:11:39 GMT):
That usually means there was an exception running your tx processor function. Usually this is because the incoming data is invalid -- often the tx has a relationship to something that is missing.

You can `docker attach` to the chaincode docker container to see the logs, or run `docker logs`

I added assets & participants. Then, on the Transactions tab, I selected the approp. Transaction from the drop down. Entered the values on the JSON data form and Hit submit

Hi @dselman, did you make any grammar changes that would affect users such as new constructs or changes to existing constructs?

dselman (Thu, 23 Feb 2017 15:05:33 GMT):
I fixed this bug https://github.com/fabric-composer/fabric-composer/issues/223 as well as one that prevented using negative values for defaults and range validators. So nothing structurally changed.

mgk (Thu, 23 Feb 2017 15:06:27 GMT):
Thanks @dselman - that's helpful :-)

dselman (Thu, 23 Feb 2017 15:06:46 GMT):
We are working on getting an automated build + publish to the marketplace for the code, which is now published here: https://github.com/fabric-composer/tools/tree/master/composer-vscode-plugin

dselman (Thu, 23 Feb 2017 15:07:13 GMT):
First step is probably to document how to build the VSIX locally and install

dselman (Thu, 23 Feb 2017 15:07:36 GMT):
Pull requests welcome! :-)

mgk (Thu, 23 Feb 2017 15:08:17 GMT):
So that first step is easy: "npm run package" will build the vsix :-)

dselman (Thu, 23 Feb 2017 15:08:32 GMT):
Oh, and I added location information to the IllegalModelExceptions... so we no longer need to parse the exception message text.

dselman (Thu, 23 Feb 2017 15:09:11 GMT):
The parser should now return line number information for almost all of the validation errors

mgk (Thu, 23 Feb 2017 15:09:56 GMT):
That's great! - will make a real difference !

mgk (Thu, 23 Feb 2017 15:12:00 GMT):

jdockter (Thu, 23 Feb 2017 16:36:34 GMT):
@dselman on the topic of events...I would like to trigger an event after a transaction is completed...in our environment we would probably want some type of message to an external system, ie MQ or REST

jdockter (Thu, 23 Feb 2017 16:46:57 GMT):
ie I have a PO I get agreement from parties in the business network, then trigger an invoice payment message to external system

dselman (Thu, 23 Feb 2017 17:09:48 GMT):
v1 has more sophisticated eventing... but it still is not very enterprise friendly IMO.

dselman (Thu, 23 Feb 2017 17:10:03 GMT):
E.g. authentication, store-and-forward support etc

dselman (Thu, 23 Feb 2017 17:10:48 GMT):
The right thing to do is to come back to the Fabric team with a set of requirements and start a discussion.

jdockter (Thu, 23 Feb 2017 17:14:34 GMT):
just want to make sure I understand...today composer doesn't have any event support correct?

dselman (Thu, 23 Feb 2017 17:16:57 GMT):
correct

dselman (Thu, 23 Feb 2017 18:33:11 GMT):
We've experimented with pushing events out over the v0.6 event hub but our feeling was we should wait until we port to v1 before exposing it.

dselman (Thu, 23 Feb 2017 18:33:48 GMT):
v1 has more interesting events that clients can subscribe to that show the lifecycle of a transaction

jdockter (Thu, 23 Feb 2017 18:42:28 GMT):
Great to know, thanks

If I have a deployed business network and have added participants and assets to it and then I update the business network with a new model of those participants and assets...what would/should happen to the old data?

jdockter (Thu, 23 Feb 2017 20:05:09 GMT):
ie I had a participant called employee they didn't have a zip code and then I added zip code and redeployed the model...assuming old data is still there correct, but zip is missing

sstone1 (Thu, 23 Feb 2017 20:06:04 GMT):
@jdockter if you update it (rather than redeploy it), the data will still be there in the world state. if you deploy a model change that adds a required field (as per your example), then any existing instances without that field will fail to parse.

sstone1 (Thu, 23 Feb 2017 20:06:37 GMT):
We are aware of that and I think it's documented _somewhere_ as a restriction; you must only make compatible changes to your model (such as adding new *optional* fields).

sstone1 (Thu, 23 Feb 2017 20:08:07 GMT):
In the future we could possibly look at some kind of migration code/tool, but for now it's a restriction. The consensus in a recent discussion was that breaking model changes shouldn't occur that regularly in production, but that's certainly something that could be debated!

jdockter (Thu, 23 Feb 2017 20:12:21 GMT):
yeah I was just thinking about development lifecycel...in sprint 1 we have model x, in sprint 5 we have model x+...just wanted to make sure I understood what would happen to any of the test data we put to the bc throughout those iterations

jdockter (Thu, 23 Feb 2017 20:21:04 GMT):
if I run composer ui locally, using npm package, so I can point to a local running business network via a connection profile...will composer ui load in the model, scripts, and ACL to the browser? Or do I need to recreate all that in the browser first and then deploy to an empty local HL instance?

omkardash (Thu, 23 Feb 2017 20:22:15 GMT):
@sstone1 If I remove the old business network from connection.json and redeploy business network with model updates, would there still be potential conflicts?

sstone1 (Thu, 23 Feb 2017 20:23:11 GMT):
not really, at least at v0.6. the old business network will still be running with an old chaincode ID. the connection profile would only reference the new chaincode ID.

sstone1 (Thu, 23 Feb 2017 20:23:55 GMT):
in v1.0 the chaincode ID will be the business network name, so that trick won't work. infact at v1.0 i don't want to see the list of deployed business networks in the connection profile.

sstone1 (Thu, 23 Feb 2017 20:24:23 GMT):
but in v1.0 we get the ability to stop and delete running chaincode, so we can properly undeploy business networks.

omkardash (Thu, 23 Feb 2017 20:25:42 GMT):
That would be good.

omkardash (Thu, 23 Feb 2017 20:26:20 GMT):
On a different note, can is there a direct way to see how assets have moved between participants?

omkardash (Thu, 23 Feb 2017 20:26:20 GMT):
On a different note, is there a direct way to see how assets have moved between participants?

sstone1 (Thu, 23 Feb 2017 20:41:38 GMT):
Not yet. We are looking into a historian component that will allow you to track the changes to an asset, so you will be able to see that the `owner` property of an asset changed over time. I think that's in our plan for the next iteration.

sstone1 (Thu, 23 Feb 2017 20:42:08 GMT):
Currently the transaction registry only shows you the inputs to transactions, and does not show changes that occur as a result of CRUD (add/update/remove) operations on an asset registry.

sstone1 (Fri, 24 Feb 2017 04:21:36 GMT):
@jdockter the current version of composer-ui does not store the files in the browser. It always uses the version in the deployed business network. The deployed business network must have a name of `org.acme.biznet`, and if that business network doesn't exist it will deploy it for you.

mbwhite (Fri, 24 Feb 2017 09:17:48 GMT):
@jdockter exactly what I was trying to yesterday - and I have managed to do it succesfully; due to the way Fabric works as @sstone1 says it's tricker. 1.0 will be different. I'll write down what I did and post it up.

Proposal for a tweak to ACLs (this is as part of the UI design, but suggesting a terminology and order-of-properties change that would effect the raw files and doc too...)

dselman (Fri, 24 Feb 2017 11:52:10 GMT):
I like the proposed structure. As you say, it should be more self-explanatory.

tom.appleyard (Fri, 24 Feb 2017 11:53:45 GMT):
Couple of questions on composer: On changing membership service enrolment credentials: Looking at the membersrvc dockerfile it looks like we should be able to extend from the hyperledger:fabric-membersrvc image and copy our own membersrvc.yaml file over the one in $GOPATH/bin? Preconfiguring fabric compose without requiring an enrolment step: should be doable by mounting a volume at /home/composer/.composer-credentials with the credentials file prefilled, correct? The Otto docs talk about using Go's interrupt channel to halt long-running code and prevent runaways. Do you guys do this out of the box, and if so is that execution limit configurable?  I notice the example code uses ES5 promises, so are you actually using https://github.com/robertkrimen/natto rather than Otto? And presumably, we can't use ES6/7 just yet either (though presumably we could transpile it via Babel or Rollup reasonably easily)

dselman (Fri, 24 Feb 2017 11:56:50 GMT):
1. Yes, in theory that should work. I've not tried to do that however.

dselman (Fri, 24 Feb 2017 11:57:47 GMT):
2. I don't think this will work. The ECert is generated by member services based on the enrollment id / secret. @sstone1 would know for sure.

dselman (Fri, 24 Feb 2017 11:58:22 GMT):
3. This is one for @sstone1. As far as I know it is not configurable.

dselman (Fri, 24 Feb 2017 11:58:53 GMT):
4. Otto supports ES5, including promises.

dselman (Fri, 24 Feb 2017 11:59:05 GMT):
5. Correct.

dselman (Fri, 24 Feb 2017 12:00:10 GMT):
It is worth pointing out that our intention is to move to executing the JS code inside a Node.js chaincode container, rather than using the Otto interpreter.

tom.appleyard (Fri, 24 Feb 2017 12:10:21 GMT):
@dselman thanks!

tom.appleyard (Fri, 24 Feb 2017 12:10:37 GMT):
Another quick question - can you call Go chaincode from composer?

dselman (Fri, 24 Feb 2017 12:11:32 GMT):
No

tom.appleyard (Fri, 24 Feb 2017 12:11:47 GMT):
are there plans to add this as a feature?

dselman (Fri, 24 Feb 2017 12:13:28 GMT):
No plans. It raises a whole slew of nasty issues around essentially calling "unmanaged code", as well as data binding/mapping between the JS side and the Go side. Personally I think our time is best spent elsewhere, particularly as people are going to have to port their Go code to HL v1 anyway.

dselman (Fri, 24 Feb 2017 12:15:04 GMT):
We just published a tool to convert Google protobufs to Composer Models, to at least provide some help for people that want to port existing solutions to use Composer: https://github.com/fabric-composer/tools/tree/master/composer-protobuf

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=YGEfFSfCujTh6LJ2C) @sstone1 I did a scenario yesterday where I added a field to an asset that was already created in my network, then updated that model of that asset in my cto file, updated the model back into my current HL instance and was unable to work with old data via rest...couldn't even delete the old registry entry by id as it saying it was missing the new field value I added...feels like that registry entry is now unusable?

dselman (Fri, 24 Feb 2017 13:01:57 GMT):
You need to make the new field `optional` or give it a default value. You can do both in your .cto file.

dselman (Fri, 24 Feb 2017 13:02:31 GMT):
We probably need to improve how we handle/log invalid data.

How about if I have the loopback server running?

mbwhite (Fri, 24 Feb 2017 16:21:36 GMT):
@jdockter BNAs shouldn't need to be regenerated; the package.json is for any applications that you might have written yourself.

@jdockter I've also written the first draft of the process I used yesterday to connect to the HLF in the Playground docker image. https://github.com/mbwhite/documents/blob/master/Connecting%20to%20playground%20HLF.md

paul.sitoh (Fri, 24 Feb 2017 16:28:42 GMT):
Folks, let's say in my data model I don't want to store personal details directly. Does compose provide some kind of callback types that can take a real value and hash it? For example, instead of storing a person name as "Paul Sitoh", I like it to store person name in Hash form.

Yes, the contents are documented on the release itself: https://github.com/fabric-composer/fabric-composer/releases/tag/v0.4.4

jdockter (Fri, 24 Feb 2017 18:55:11 GMT):
okay...where can I find out more about, 'Load sample networks from GitHub into Playground (Composer UI)' ?

dselman (Fri, 24 Feb 2017 18:56:22 GMT):
Basically the Composer-UI now pulls samples from https://github.com/fabric-composer/sample-networks when you click the import sample button. This makes it easier for us to publish new samples and keep them up to date.

jdockter (Fri, 24 Feb 2017 18:57:02 GMT):
So I would see that option now if I repull composer ui locally?

dselman (Fri, 24 Feb 2017 18:58:19 GMT):
Yes. Unfortunately when we use the public GitHub API to access those repos we can hit rate limits -- so if you don't see the samples, it is likely because we've hit a rate limit cap. In the new Playground we're using OAuth to work around that.

jdockter (Fri, 24 Feb 2017 19:00:30 GMT):
okay I will give that a try, thanks

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=ayDss87nFgozFMuA8) @paul.sitoh No, we don't have this feature. Can you describe in more detail how you'd like this to work?

sstone1 (Fri, 24 Feb 2017 20:24:42 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=u9jMJLW9qXag4By6y) @dselman @tom.appleyard you always need to enroll using an enrollment ID and enrollment secret. If you have already enrolled, then Tom is correct; you can simply place the ECert (member.tom1) file in the right directory and Composer will use it without trying to enroll again.

sstone1 (Fri, 24 Feb 2017 20:26:33 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=uspXgNwQhvYr4EPNn) @dselman @tom.appleyard we are using the example code from Natto (which basically adds two functions to Otto) to add event loop support required to support promises and async callbacks. I'd rather we keep referring to it as "we use Otto" as the bulk of the code is Otto (I have no idea why robertkrimen didn't just make the Natto stuff a feature of Otto)

sstone1 (Fri, 24 Feb 2017 20:28:44 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=BBWRS7aLXFXkw5ngi) @dselman @tom.appleyard correct, we don't currently make any attempt to timeout transaction processor functions. I'd rather not try to do anything with Go channels at this point, as although it's entirely possible we might end up building functionality that is difficult to port to Node.js (@davidkel this is one to bear in mind for the future - timing out Node.js chaincode)

sstone1 (Fri, 24 Feb 2017 20:29:56 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=TYcCh9qHDzsFGeCXF) @dselman @tom.appleyard correct, and just to expand as an FYI, we Babelify all of our JavaScript runtime code (written in ES6) and use the Babel polyfill in Otto to provide Promise support.

sstone1 (Fri, 24 Feb 2017 20:38:14 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=o82PQRq8Efpnuy2N3) @EdMoffatt I :heart: this (participant operation resource vs resource operation participant), but I am conscious that we've already gone round this recently as I raised the same point about it being easier to read/speak/understand as a result of the workshops.

sstone1 (Fri, 24 Feb 2017 20:38:57 GMT):
I am not keen on the UI showing a different order to the underlying ACL file though, that seems a bit odd.

sstone1 (Fri, 24 Feb 2017 20:39:18 GMT):
(as in, we should change the ACL file if we agree it's the way to go)

sstone1 (Fri, 24 Feb 2017 20:40:02 GMT):
Ah, I think Ed already hinted at that... I'll shut up now ;)

sstone1 (Fri, 24 Feb 2017 20:43:20 GMT):
@paul.sitoh just to discuss GitHub issue #264 (TDD in Composer), have you seen that we support unit testing transaction processor functions in Node.js using our "embedded runtime"? For example: https://github.com/fabric-composer/sample-networks/blob/master/packages/DigitalProperty-Network/test/DigitalLandTitle.js

jdockter (Fri, 24 Feb 2017 20:45:01 GMT):
When I run composer ui locally, after installing via npm, if I want to use the Deploy, are all the files listed in my Editor used?

sstone1 (Fri, 24 Feb 2017 20:45:18 GMT):
@jdockter yes, when you deploy, all files in the editor are added to the BNA and deployed.

jdockter (Fri, 24 Feb 2017 20:46:06 GMT):
so what is the default acl string...tried to remove the example and it's giving me errors

jdockter (Fri, 24 Feb 2017 20:46:47 GMT):
or should I just reset the network?

sstone1 (Fri, 24 Feb 2017 20:47:01 GMT):
the namespace must be correct though

jdockter (Fri, 24 Feb 2017 20:48:06 GMT):
Error: Expected [\n\r\u2028\u2029] but end of input found. Line 1 column 102

sstone1 (Fri, 24 Feb 2017 20:49:13 GMT):
you need a newline at the end of the file

jdockter (Fri, 24 Feb 2017 20:49:31 GMT):
mmm, leave that page and the default comes right back :)

sstone1 (Fri, 24 Feb 2017 20:49:31 GMT):
... ideally you shouldn't though ...

sstone1 (Fri, 24 Feb 2017 20:49:44 GMT):
yeah, if you don't deploy the changes are discarded ;)

sstone1 (Fri, 24 Feb 2017 20:49:56 GMT):

jdockter (Fri, 24 Feb 2017 21:26:38 GMT):
since I was working locally before I started with composer-ui I now have two dev-vp0- containers...so guess that makes sense

jdockter (Fri, 24 Feb 2017 21:28:00 GMT):
I installed with npm so no docker composer-ui container

sstone1 (Fri, 24 Feb 2017 21:28:50 GMT):
ah okay, it would have been the stdout of the composer-ui command

sstone1 (Fri, 24 Feb 2017 21:29:02 GMT):
it's possible that it crashed when you get the "Cannot GET" errors

jdockter (Fri, 24 Feb 2017 21:29:56 GMT):
well it didn't seem to crash the terminal command...I did that manually and then restarted via 'composer-ui' command

jdockter (Fri, 24 Feb 2017 21:33:49 GMT):
so it looks like it deployed the auction model...so probably should have just connected locally first...then started to build up my business network as nothing really came from the web profile

jdockter (Fri, 24 Feb 2017 21:34:27 GMT):
or is that not the expected behavior

jdockter (Fri, 24 Feb 2017 21:34:29 GMT):
?

sstone1 (Fri, 24 Feb 2017 21:36:32 GMT):
nothing will be migrated between connection profiles

sstone1 (Fri, 24 Feb 2017 21:37:02 GMT):
the business network definition is stored in the "blockchain" (either real HLF or web browser) and so it doesn't migrate as you switch connection profiles

jdockter (Fri, 24 Feb 2017 21:53:28 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=T7QxmqGpiqS3F2fir) @mbwhite so what I ended up doing is installing composer-ui locally via npm, then I used the hlfabric connection profile to deploy the default auction network locally, ie it created on my local machine a new docker dev-vp0- container and a hlfabric connection profile under .composer-connection-profiles...when I connected I just had to provide the 'admin' identity and secret/password of 'Xurw3yU9zI0l'...then I used the editor to load my own model, script and acl and deleted the default auction files from the editor...lastly I deployed the network which just did an update of the exist default auction network...now I seem to have my local composer-ui managing my business network

Just diving in for a project that of course has a tight schedule. I had an ubuntu 16 from some old busywork testing I did ... but when I wanted to install composer, I saw that my node and npm were too old, so not having upgrades in current repositories, I followed instructions here: http://tecadmin.net/install-latest-nodejs-npm-on-ubuntu/# which put my node and npm a little bit ahead. When I tried: npm install -g composer-cli ... it lost its mind a little. Looking to include file (maybe that's only w/my full client which seems to only work with slack.com sites. Anyway, with slightly too new node and npm on ubuntu 16 ... command lost it badly.

@MikeC711 Fabric currently supports grpc 1.0.0 which doesn't support Node 7. We need Fabric to upgrade grpc. E.g. https://github.com/grpc/grpc/issues/8495

dselman (Sat, 25 Feb 2017 05:09:10 GMT):

I am having trouble installing Composer on a MacOS environment. I followed the instructions in the Quickstart link that's on fabric-composer.org. This worked though it doesn't get me to a point where I have something to run. So I tried Lab 4: Installing and Running the Fabric Composer Generator (Angular). This works quite well until I get to the point of running Fabric Composer Generator (Angular) - Section 2, #4. It says to open a new window and type "yo" I do this and I see: ? 'Allo Stuart!

Hi there. I am in a team working on a blockchain project, and we've chosen fabric as our base platform. But we want the ability to quantify the resources used by every chaincode execution. So we want to know if there are any maintainers currently working on integrating fabric with Ethereum EVM or doing similar things.

dselman (Sun, 26 Feb 2017 14:46:10 GMT):
@blackskygg interesting. Can you share the purpose of the quantification and the required granularity?

dselman (Sun, 26 Feb 2017 15:18:12 GMT):
@venkatrammohan @barath -- this has been fixed. Sorry, we changed the arguments to `composer archive create` and the gettingstarted package.json script was not updated.

stuartcjones (Sun, 26 Feb 2017 18:39:22 GMT):
I take back what I said above. I figured out that "Fabric Composer" might be an option and so I clicked on this. Eventually, I had a generated Angular application that gave me access to the digitalPorpety business network.

stuartcjones (Sun, 26 Feb 2017 18:41:14 GMT):
However, this is not what I am actually trying to do. I want to get access to the Composer tool and build my own business network. I thought that this what what I was doing but it turns out not to be the case. I will look through the other labs to see if I can find one that shows how to get access to the tool ... unless someone can point me at that?

what's the simplest way to free up the ports (for someone like me that is a docker newbie) ?

Can I just restart docker and re-run the docker-compose command?

sstone1 (Sun, 26 Feb 2017 19:42:25 GMT):
`docker ps -aq | xargs docker rm -f`

sstone1 (Sun, 26 Feb 2017 19:42:30 GMT):
that deletes all running docker containers

No problem. Safari is fine, as is Chrome. I don't think many people have tried IE/Edge yet though.

While @Jakeeyturner is making the fix (sorry, again!) here is the workaround.

dselman (Mon, 27 Feb 2017 09:59:34 GMT):
1. Make sure you are running Node 6. I tested this with Node v6.9.5

dselman (Mon, 27 Feb 2017 10:01:06 GMT):
2. Once you are running Node 6, globally install the following: composer-cli, bower, typings, @angular-cli, yo, generator-fabric-composer

dselman (Mon, 27 Feb 2017 10:01:06 GMT):
2. Once you are running Node 6, globally install the following: composer-cli, bower, typings, @angular/cli, yo, generator-fabric-composer

dselman (Mon, 27 Feb 2017 10:01:41 GMT):
3. Run the QuickStart, as described here: https://fabric-composer.github.io/start/quickstart.html

dselman (Mon, 27 Feb 2017 10:02:58 GMT):
4. Type: yo and select the Fabric Composer option

dselman (Mon, 27 Feb 2017 10:03:19 GMT):
5. Select Angular2 Application

dselman (Mon, 27 Feb 2017 10:03:37 GMT):
6. Select the option to use a running network

dselman (Mon, 27 Feb 2017 10:04:06 GMT):
7. Other options can remain defaults

dselman (Mon, 27 Feb 2017 10:04:49 GMT):
8. Wait for the generator to complete...

dselman (Mon, 27 Feb 2017 10:06:03 GMT):
9. cd into the directory for the generated app

dselman (Mon, 27 Feb 2017 10:06:15 GMT):
10. npm uninstall --save-dev angular-cli

dselman (Mon, 27 Feb 2017 10:06:24 GMT):
11. npm install --save-dev @angular/cli@latest

dselman (Mon, 27 Feb 2017 10:06:52 GMT):
12. Edit angular-cli.json as follows:

dselman (Mon, 27 Feb 2017 10:07:03 GMT):
Before: "environments": { "source": "environments/environment.ts", "dev": "environments/environment.ts", "prod": "environments/environment.prod.ts" } After: "environmentSource": "environments/environment.ts", "environments": { "dev": "environments/environment.ts", "prod": "environments/environment.prod.ts" }

dselman (Mon, 27 Feb 2017 10:09:19 GMT):
13. Type ng serve

dselman (Mon, 27 Feb 2017 10:09:34 GMT):
14. In a new terminal run `node app.js`

dselman (Mon, 27 Feb 2017 10:10:26 GMT):
15. Go to: http://localhost:4200

dselman (Mon, 27 Feb 2017 10:10:52 GMT):
16. You should see the LandTitles when you select Assets > LandTitle

dselman (Mon, 27 Feb 2017 10:11:36 GMT):
We will update the docs as well as the generated code to take into account these changes in Angular ASAP.

Sorry to pester, but still trying to get started. On an ubuntu 16.0.4 VM, I had troubles on too current a node and npm, so I now have node: v6.10.0 and npm: 4.3.0 which would appear to be OK. I will be uploading the full file with the output, but I definitely see some of what appear to be troublesome messages:when I try: npm install -g composer-cli npm WARN deprecated node-uuid@1.4.7: use uuid module instead gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/6.10.0" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/lib/node_modules/composer-cli/node_modules/hashtable/.node-gyp" > grpc@1.0.0 install /usr/lib/node_modules/composer-cli/node_modules/grpc > node-pre-gyp install --fallback-to-build Then it seems to think things are OK until I finish with: npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/composer-cli/node_modules/chokidar/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.1: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"}) Trying to see where I'm going wrong.

@MikeC711 from your earlier error, it would appear that there is an issue access the homedir for the user root. E.g. `gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/6.10.0"` Can you try using a non-root user please?

Didn't mean to send that yet. Should I have picked it up at some point after that such as: git clone https://github.com/fabric-composer/sample-applications.git Anyway, seeing that composer was there from root ... I went ahead with the following commands as non-root (since npm install -g composer-cli did not work as non-root) All was going well until on npm install it could not find docker. I configured this docker back when doing Blockchain testing of Busywork back in the day ... so I'm not sure if I should be specifying something different, or if this is because I'm nonRoot and I need some special configuration to run these docker commands as non-root. I am sending all of the details. Note the not finding docker and (as a result?) the errors at the bottom wrt the daemon. Thanks,

Can anyone help me find in the source code what the API of the chaincode itself is? (So, what are the invoke and query function names that are being used and what do you send as arguments)?

dselman (Mon, 27 Feb 2017 20:35:36 GMT):
Hi @arner, this is a pretty key class: https://github.com/fabric-composer/fabric-composer/blob/master/packages/composer-connector-hlf/lib/hfcutil.js // note that this is not public API, so may change at any time.

dselman (Mon, 27 Feb 2017 20:36:21 GMT):
It is called from https://github.com/fabric-composer/fabric-composer/blob/master/packages/composer-connector-hlf/lib/hfcconnection.js where you can see the names of the function names passed.

dselman (Mon, 27 Feb 2017 20:36:44 GMT):

arner (Mon, 27 Feb 2017 20:39:22 GMT):

sstone1 (Mon, 27 Feb 2017 20:40:26 GMT):
@arner I'd grep the `composer-client` source tree looking for `queryChainCode` and `invokeChainCode`

I'll second Dan's query asking what you're upto ;)

arner (Mon, 27 Feb 2017 20:43:15 GMT):
Hehe not much, mostly curiosity and I thought I might learn something... As you know we also try to keep our boilerplate application up to date and it's in our interest to make the chaincode as interchangable as possible (between golang and composer). Adopting an API standard in the chaincode could be one part of it. Not sure yet! Anyway it's good to learn a bit about the internals :)

arner (Mon, 27 Feb 2017 20:44:30 GMT):
But yeah Dan, your warning of it not being a public API is noted!

Hi, I'm trying to generate a JAX-RS client to the Vehicle Auction sample. This issue means I have no Swagger for the transactions (e.g. "Offer"). Does it also mean that there are no REST APIs to call, or just that there's no Swagger?

silliman (Tue, 28 Feb 2017 17:18:54 GMT):
has anyone gone through the "getting started" to the point where they see the LandTitle assets at localhost:4200 on a *Linux on z Systems* instance? I just started dipping my toes into the Composer pool and had some issues with the npm install of the pre-requisite stuff. I didn't find a real quick fix so I did what I usually do- try to get it working on Linux on x86, which I did... so, before I got back to dig in to debugging back on z Systems, I'd be curious to know if others have made this work on "zed"

silliman (Tue, 28 Feb 2017 17:19:55 GMT):
I should clarify- I had issues with npm install up on Linux on z... like I said, I reached nirvana on x86 on Ubuntu 14.04 :-)

sstone1 (Tue, 28 Feb 2017 17:22:15 GMT):
@silliman we haven't done a lot of testing on Linux on z, but we have got as far as deploying Composer to Hyperledger Fabric on z and standing up a Loopback server.

sstone1 (Tue, 28 Feb 2017 17:22:26 GMT):
I think you're breaking new ground going through the app generation though ;)

sstone1 (Tue, 28 Feb 2017 17:22:42 GMT):
What node version are you running on Linux on z?

silliman (Tue, 28 Feb 2017 17:24:55 GMT):
I was at 6.7 at first then I tried it with 6.10 I think..... i was getting the same error both times, it was complaining about grpc or something... i was following the "workaround" steps related to the angular update posted yesterday... this was in the first global npm install with composer-cli, bower, typings, etc.

silliman (Tue, 28 Feb 2017 17:26:07 GMT):
@sstone1 when you say Loopback server, do you mean the one listening on port 4200 spun up by *ng serve* ?

sstone1 (Tue, 28 Feb 2017 17:27:25 GMT):
6.10 is known not to work, I know that much. The Loopback server is the REST API that runs on port 3000 (you will have seen the StrongLoop API Explorer)

silliman (Tue, 28 Feb 2017 17:29:46 GMT):
@sstone1 since Linux on z sometimes presents "challenges" not associated with x86, my usual modus operandi if something breaks on z is to see if I can get it to work on x86, sort of as a sanity test....so I didn't debug things too hard on z, but I'm ready to now. hmm I didn't come across 3000, so either that is behind the scenes or I'm not looking at the same set of instructions... basically on x86 I followed the workaround steps posted here by dselman at UTC 9:59 AM (if I did my math right) yesterday 2/27

sstone1 (Tue, 28 Feb 2017 17:31:05 GMT):
Did you run `yo` to generate an application that is running on 4200?

silliman (Tue, 28 Feb 2017 17:31:54 GMT):
yes.... got that and got the Land Title assets.... I just updated one of the assets to change the description, worked well... that's as far as I got. (on x86 of course)

sstone1 (Tue, 28 Feb 2017 17:32:24 GMT):
Oh, sorry, ignore the Loopback point. We haven't ported the app generator to use the Loopback server yet.

silliman (Tue, 28 Feb 2017 17:35:04 GMT):
if you happen to know which distro (Ubuntu, SLES or RHEL) was used up on Linux on z, and which levels of node and npm, I can try to replicate with those levels (and if you used the IBM-supported Docker images for Fabric v0.6 or built your own images or ran natively, that would help too)

silliman (Tue, 28 Feb 2017 17:38:03 GMT):
btw you guys have put together some very impressive automation with regards to installing the pre-reqs on x86 Ubuntu Trusy and pulling down the hyperledger docker images and spinning up the network.... great job on the automation and the documentation!!

@sstone1 Ok, that'll work....I'll try some more... I was playing around on Redhat and I think I'll switch over to Ubuntu and avoid node 6.10 per your advice.... I'll see if I can find 6.9.5 for z, sometimes finding older versions for z can be tricky

Hi All, I have managed to create channels using the dockerized cli. I am attempting to do the same using fabric-composer is it currently possible to create/deploy a channel using fabric-composer?

ayoub (Tue, 28 Feb 2017 18:42:25 GMT):
i.e using: composer network deploy < some option to deploy to a channel >

sstone1 (Tue, 28 Feb 2017 19:49:28 GMT):
@Ayoub Naciri I take it you are using v1.0? Are you using the very new v1.0 functionality I delivered a couple of days ago?

sstone1 (Tue, 28 Feb 2017 19:51:42 GMT):
For our v1.0 support (which is currently being worked on), we are going to require that you specify a name of an existing channel in a Fabric Composer connection profile. We don't want to get into the business of trying to create channels and adding peers to channels; that's really an operational concern for the Fabric administrators (and possibly Cello).

ayoub (Tue, 28 Feb 2017 21:20:24 GMT):
@sstone1 haven't update for a few days now, so using the 'older' version. i imagine i can update via npm or need to pull from source? what I was doing was after creating a biz definition calling:

ayoub (Tue, 28 Feb 2017 21:20:40 GMT):
composer network deploy -a -i WebAppAdmin -s DJY27pEnl16d

ayoub (Tue, 28 Feb 2017 21:21:22 GMT):
could you please give details how to specify the channel?

sstone1 (Tue, 28 Feb 2017 21:24:01 GMT):
@Ayoub Naciri at the moment we haven't done any documentation about how to use Fabric Composer with v1.0. That code is changing rapidly to keep up with the development of Fabric itself (for example the recent rework around deploy to be split into install & instantiate). Once it's a bit more stable we'll get the process documented.

sstone1 (Tue, 28 Feb 2017 21:24:09 GMT):
For now I would stick with v0.6.

Those of you experimenting with using the REST API generated from a business network -- we've just made that even easier for developers and would love your feedback. https://github.com/fabric-composer/fabric-composer/tree/master/packages/composer-rest-server

conroydave (Wed, 01 Mar 2017 05:55:55 GMT):
i dont quite understand it

conroydave (Wed, 01 Mar 2017 05:56:16 GMT):
can you explain the business network part

smithsj (Wed, 01 Mar 2017 08:03:47 GMT):
@conroydave the Fabric Composer REST Server can be used to quickly create a REST API that developers can invoke to interact with a business network. It uses the LoopBack connector to connect to the Business Network that you suppy details of, then runs a web server that hosts an application that provides the REST API from swagger doc. HTH

conroydave (Wed, 01 Mar 2017 08:08:47 GMT):
so you feed it your existing api for what ever your app is, say counting parking spaces, and then it spins up an server&api so that it can be interacted from participants in the hyperledger network?

conroydave (Wed, 01 Mar 2017 08:09:00 GMT):
ive got a lot to learn, not sure what Swagger is

smithsj (Wed, 01 Mar 2017 09:09:56 GMT):
So you define your business network in terms of the assets that it will track, the participants that are involved, the transactions that can be executed and the acls that are in force. This is sometimes known as 'the model' and you can use the fabric composer playground to do that. Then you deploy that definition (a .cto file) to the blockchain fabric (the peers) to make it real and allow you to develop applications that interact with 'ledger' that this model represents. The composer-rest-server uses fabric composer to connect to one of the peers in the network to retrieve the model definition and then runs the REST server that exposes that model via an API.

smithsj (Wed, 01 Mar 2017 09:11:40 GMT):
This is a useful definition from the swagger site: "Swagger is a set of rules (in other words, a specification) for a format describing REST APIs. The format is both machine-readable and human-readable. As a result, it can be used to share documentation among product managers, testers and developers, but can also be used by various tools to automate API-related processes."

conroydave (Wed, 01 Mar 2017 09:13:02 GMT):
is it common for many models to run on a single fabric(group of peers)?

smithsj (Wed, 01 Mar 2017 09:15:10 GMT):
That's a good question. I don't believe it is.

conroydave (Wed, 01 Mar 2017 09:15:30 GMT):
is calling it composer a nod to docker?

conroydave (Wed, 01 Mar 2017 09:15:34 GMT):
or just a coincidence

smithsj (Wed, 01 Mar 2017 09:17:09 GMT):
It's just a coincidence really :)

conroydave (Wed, 01 Mar 2017 09:19:04 GMT):
im speaking to a group of MLS vendors at the end of the month so i am very happy to see the sample code is a land registry!

conroydave (Wed, 01 Mar 2017 09:19:20 GMT):
presenting on blockchain

conroydave (Wed, 01 Mar 2017 09:20:32 GMT):
so they key here is the loopback connector that exposes it to external systems

conroydave (Wed, 01 Mar 2017 09:20:35 GMT):
the*

smithsj (Wed, 01 Mar 2017 09:21:09 GMT):
so to go back to the question of whether it's 'normal' to run many models on a single fabric, I believe that it is possible since each business network is run in a separate chaincode container with a different id

conroydave (Wed, 01 Mar 2017 09:21:46 GMT):
right, i could see the same parties being interested in different business transactions

smithsj (Wed, 01 Mar 2017 09:21:49 GMT):
whether you want to do that or perhaps you have stringent rules about data isolation for example

smithsj (Wed, 01 Mar 2017 09:21:57 GMT):
yes, sure

conroydave (Wed, 01 Mar 2017 09:22:03 GMT):
exactly

smithsj (Wed, 01 Mar 2017 09:22:14 GMT):
it all depends on the use case really :)

conroydave (Wed, 01 Mar 2017 09:22:40 GMT):
i work for a large trade organization, has 3 levels. National, State, and city

conroydave (Wed, 01 Mar 2017 09:22:50 GMT):
we all serve the same people, but dont share data very well

conroydave (Wed, 01 Mar 2017 09:23:20 GMT):
all of the data is centralized at the national level and not shared back

conroydave (Wed, 01 Mar 2017 09:23:53 GMT):
all in oracle databases that dont track history well

conroydave (Wed, 01 Mar 2017 09:24:05 GMT):
systems we use were designed in the 90s

smithsj (Wed, 01 Mar 2017 09:24:51 GMT):
so they are SORs (systems of record)

conroydave (Wed, 01 Mar 2017 09:24:58 GMT):
yes.

conroydave (Wed, 01 Mar 2017 09:25:21 GMT):
and at this point the national association has gathered an incredible amount of data that itd be difficult to segment it off for sharing

conroydave (Wed, 01 Mar 2017 09:25:35 GMT):
anyway, perfect opportunity to introduce new tech

smithsj (Wed, 01 Mar 2017 09:26:10 GMT):
yes, well the loopback connector is designed with this sort of integration with SORs in mind

@sstone1 right now mainly experimenting for the fun of it ;-) , quick question is there any location where composer spits out the chaincode ? I understand composer abstracts dealing with the low level stuff but just for diagnostics/troubleshooting

is the GOPATH relevant?

mbwhite (Wed, 01 Mar 2017 14:30:55 GMT):
I'd suggest it might be worth running the `npm run teardownHLF` command.. and then doing `npm install` again... for just the getting started application there seems to be one too many docker images working

from within the getting started directory

uber.twin (Wed, 01 Mar 2017 14:47:02 GMT):
the same outcome

Jakeeyturner (Wed, 01 Mar 2017 14:55:17 GMT):
Have you made any code changes or is this a result of just following https://fabric-composer.github.io/start/quickstart.html ?

smithsj (Wed, 01 Mar 2017 14:55:39 GMT):
the peer log suggests that the peer never actually gets told to deploy the business network

smithsj (Wed, 01 Mar 2017 15:00:09 GMT):
do you have any extra DEBUG enabled? ie. what is the result of `echo $DEBUG`

uber.twin (Wed, 01 Mar 2017 15:00:52 GMT):
empty output

uber.twin (Wed, 01 Mar 2017 15:01:18 GMT):
I didn't touch the code, just went with the guide

mbwhite (Wed, 01 Mar 2017 15:11:44 GMT):
Where there any errors when you did npm install in the getting started directory?

Jakeeyturner (Wed, 01 Mar 2017 15:13:39 GMT):
@uber.twin Can you try `docker rm $(docker ps -a -q)` (this'll take down any docker containers) then can you run `docker rmi $(docker images -q)` (this'll delete all docker images)

Jakeeyturner (Wed, 01 Mar 2017 15:14:05 GMT):
Then can you try an `npm install` again in the getting started again

smithsj (Wed, 01 Mar 2017 15:14:39 GMT):
yeah, if it's a docker issue then that'll likely solve it :)

uber.twin (Wed, 01 Mar 2017 15:34:58 GMT):

excellent!

Jakeeyturner (Wed, 01 Mar 2017 15:36:40 GMT):
@uber.twin Awesome! No worries. I think the problem was that you somehow had the wrong Hyperledger Fabric peer images which were named the same as what our script tries to pull down :)

Jakeeyturner (Wed, 01 Mar 2017 15:37:02 GMT):
Have you tried to use Fabric V1 preview images?

jdockter (Wed, 01 Mar 2017 15:38:05 GMT):
is there any way to startup composer-ui without the default auction business network? really just want to work with a blank slate and just end up deleting those in the editor anyway

Jakeeyturner (Wed, 01 Mar 2017 15:39:41 GMT):
@jdockter Not at the moment

uber.twin (Wed, 01 Mar 2017 15:45:36 GMT):
@Jakeeyturner probably because I already had the regular fabric setup with the node sdk in place already

uber.twin (Wed, 01 Mar 2017 15:45:55 GMT):
I also attempted to do a fabric and fabric-ca build to give the java-sdk a try, as there is no prebuilt image which works with the java-sdk- or so I was told

uber.twin (Wed, 01 Mar 2017 15:46:18 GMT):
those experiments may have left conflicting images

Jakeeyturner (Wed, 01 Mar 2017 15:47:14 GMT):
Ah right, yeah that might've done it

uber.twin (Wed, 01 Mar 2017 15:49:53 GMT):
I didn't manage to build a functional fabric setup for java-sdk, anyway

uber.twin (Wed, 01 Mar 2017 15:52:21 GMT):
meanwhile, dselman pointed me to the fabric-composer initiative and I though it is worth a shot

uber.twin (Wed, 01 Mar 2017 15:55:06 GMT):
not sure about the Fabric V1 preview images, any specific reference?

ayoub (Wed, 01 Mar 2017 15:57:36 GMT):
@Jakeeyturner actually looking for the chaincode bytecode that gets deployed to fabric. the idea is to manually load the chaincode when troubleshooting/debuggin

Jakeeyturner (Wed, 01 Mar 2017 15:59:52 GMT):
@uber.twin If you were trying to pull down your own images and build them, then I imagine that's what the problem was. I wasn't sure if you'd tried to pull down hyperledger fabric v1 preview images, as that could've caused the problem also. Let us know how you get on with Fabric Composer :)

uber.twin (Wed, 01 Mar 2017 16:05:14 GMT):

@conroydave not sure I understand, can you elaborate please. Several of the team use Macs...

conroydave (Wed, 01 Mar 2017 18:32:56 GMT):
the scripts in composer, a few remove the existing profiles and credentials in the home directory for a clean exit

conroydave (Wed, 01 Mar 2017 18:33:25 GMT):
then when they are regenerated, atleast for me, they set the peer and member urls in the default connection to localhost:7051 etc

conroydave (Wed, 01 Mar 2017 18:33:54 GMT):

dselman (Wed, 01 Mar 2017 19:29:39 GMT):
it submits a transaction which updates the state of the property listing on the ledger

so in the land registry tutorial, you start with a digital property network definition

conroydave (Wed, 01 Mar 2017 22:25:21 GMT):
then later in the tutorial, you make a single change to the business logic

conroydave (Wed, 01 Mar 2017 22:25:35 GMT):
makes perfect sense in terms of being adaptable for business

conroydave (Wed, 01 Mar 2017 22:25:57 GMT):
what i am struggling to wrap my head around though is the tracking of changes to the business rules

conroydave (Wed, 01 Mar 2017 22:28:10 GMT):
coming from bitcoin and ethereum... things in the chain can not be altered after the fact (without a fork)

conroydave (Wed, 01 Mar 2017 22:42:30 GMT):
the whole update / deletion of assets and business rules goes against my understanding of immutability

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=psydn5HzwXh6KBgbs) @mohamoud.egal You also need [this](https://github.com/fabrice102/node-hashtable/) hashtable instead of the original one. The original doesn't compile on current OS X versions

conroydave (Thu, 02 Mar 2017 02:06:27 GMT):
In the overview of composer it lists this as a feature "Provides integration extension points to send transactions to external analytics data stores"

conroydave (Thu, 02 Mar 2017 02:06:37 GMT):
Any examples of this ?

mohamoud.egal (Thu, 02 Mar 2017 02:27:12 GMT):
@raghavsood I resolved the issue earlier, but should I still install this hashtable anyway?

raghavsood (Thu, 02 Mar 2017 02:28:09 GMT):
If you're still getting the `tr1/unordered_map` error, then yes

dselman (Thu, 02 Mar 2017 02:46:56 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=t7evjQxMHionZrPst) @conroydave those are separate blockchain transactions that are all captured on the ledger. If you could not change data on the ledger it would not be very useful. It is immutable in the sense that there's a shared/replicated history of all assets.

dselman (Thu, 02 Mar 2017 02:48:48 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=QagYxo8eoo4vbQ3cv) @conroydave the "rules" (business network definition) are themselves on the ledger. It is possible to replay from the genesis block all transactions (including changes to the business network definition) and arrive at a deterministic endpoint.

conroydave (Thu, 02 Mar 2017 02:49:19 GMT):
Cool. That makes sense

conroydave (Thu, 02 Mar 2017 02:49:33 GMT):
What are the best tools for replay

conroydave (Thu, 02 Mar 2017 02:50:23 GMT):
Or will they just come with time. I've seen the basic explorers

dselman (Thu, 02 Mar 2017 02:51:17 GMT):
I'm not aware of tools for Fabric replay. Overtime I'm sure we'll see Fabric APIs that allow you to replay the chain, snapshot, or grab the state of the chain at a given point in time.

conroydave (Thu, 02 Mar 2017 02:52:10 GMT):
At the point you'll get the second wave of adopters

We can't all be true believers :nerd:

dselman (Thu, 02 Mar 2017 02:53:49 GMT):
Yes, and Fabric Composer will be ready for them! For example, "Show me the history of asset XYZ", or "Show me all transactions that impacted asset XYZ"

conroydave (Thu, 02 Mar 2017 03:00:58 GMT):
So how about the 'integration points to send transactions to external analytics' feature. Anyone doing that yet ?

conroydave (Thu, 02 Mar 2017 03:01:17 GMT):
Is that just another way of saying that it provides the series of apis

conroydave (Thu, 02 Mar 2017 03:01:45 GMT):
Or is There a way to push data externally through composer

dselman (Thu, 02 Mar 2017 03:04:48 GMT):
We did prototype that using the v0.6 event bus. We pulled the code out for the moment and are waiting for v1. The idea is that there are runtime APIs to emit events to the event bus that can get picked up by external systems.

dselman (Thu, 02 Mar 2017 03:05:36 GMT):
Once we can get the events onto a bus, then we can provide plugins to various analytics engines, like Apache Spark etc.

conroydave (Thu, 02 Mar 2017 03:06:59 GMT):
Rough timeframe for v1?

Hey all, I am trying to setup a rest api for the carauction-network. On the getting started guide it provides details for the digitalproperty-network, and has the details you need. Should I use different details when I am setting up the api for the CarAuction network? Namely the Business network ID? I am currently getting the error: (node:12824) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: No chaincode ID found for business network 'CarAuction-Network'

KeesJansen (Thu, 02 Mar 2017 11:18:25 GMT):
Also, I can't seem to find the loopback setup guide. Can anyone point me in the right direction?

dselman (Thu, 02 Mar 2017 11:25:15 GMT):
@KeesJansen the easiest way to stand up a REST server for a business network is using this: https://github.com/fabric-composer/fabric-composer/tree/master/packages/composer-rest-server

dselman (Thu, 02 Mar 2017 11:26:36 GMT):
Note that we are still working on the Loopback Connector and have some open issues: https://github.com/fabric-composer/fabric-composer/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aopen%20Loopback

KeesJansen (Thu, 02 Mar 2017 11:49:24 GMT):
Seems to be pointing me to the /home/usr/.composer-connection-profiles/default directory, however on disk this directory is /home/usr/.composer-connection-profiles/defaultProfile ..

dselman (Thu, 02 Mar 2017 11:52:26 GMT):
To test this, you can: `npm install` and then `npm test` the getting started. Then `npm install -g composer-rest-server` followed by running `composer-rest-server`.

dselman (Thu, 02 Mar 2017 11:53:08 GMT):
You should use `defaultProfile` as the Fabric Connection Profile Name

dselman (Thu, 02 Mar 2017 11:54:36 GMT):
```Enter your Business Network Identifier : digitalproperty-network Enter your Fabric username : WebAppAdmin Enter your secret: DJY27pEnl16d```

dselman (Thu, 02 Mar 2017 11:54:52 GMT):
Then go to `http://0.0.0.0:3000/explorer`

dselman (Thu, 02 Mar 2017 11:55:16 GMT):
You should see the API explorer:

Hi, thanks for that - I have done this. What I am trying to do it the same but with the CarAuction-network. I am trying to find the details to put in when setting up using "composer-rest-server".

GrahamCharters (Thu, 02 Mar 2017 13:41:28 GMT):
@dselman - where can @KeesJansen and myself find the equivalent steps to do this for the CarAuction-Network? I've been through quick start, etc, cloned the sample-networks, done npm install and npm test in the carauction-network sample and npm installed composer-rest-server.

jdockter (Thu, 02 Mar 2017 13:42:49 GMT):
@KeesJansen if you build car auction via command line locally I believe the network name is going to be 'org.acme.vehicle.auction' with WebAppAdmin and DJY27pEnl16d

jdockter (Thu, 02 Mar 2017 13:47:30 GMT):
If you deployed via composer playground it's going to be a different name (org.acme.biznet) and you would want to follow the work around instructions that @mbwhite put together here https://github.com/mbwhite/documents/blob/master/Connecting%20to%20playground%20HLF.md

GrahamCharters (Thu, 02 Mar 2017 14:12:53 GMT):
Apologies for the dumb questions - I think I'm missing some steps/concepts... Is that what was being suggested when starting the composer-rest-server? ? Enter your Fabric Connection Profile Name: defaultProfile ? Enter your Business Network Identifier : org.acme.vehicle.auction ? Enter your Fabric username : WebAppAdmin ? Enter your secret: DJY27pEnl16d Connection fails: Error: No chaincode ID found for business network 'org.acme.vehicle.auction' It will be retried for the next request. Loopback Connector for Fabric Composer (node:2704) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: No chaincode ID found for business network 'org.acme.vehicle.auction'

jdockter (Thu, 02 Mar 2017 14:16:56 GMT):
The assumption is that you have deployed that network to your local environment and that busn network identifier would be in your defaultProfile under the 'networks' section of the connection.json

jdockter (Thu, 02 Mar 2017 14:17:15 GMT):
or whatever profile you used to connect to your local environment

GrahamCharters (Thu, 02 Mar 2017 14:20:04 GMT):

I believe this was already mentioned...but just double checking...is the thought that this server would run in it's own docker container in production pointing at a specific peer or could it really be any peer (at least in v0.6)?

mohamoud.egal (Fri, 03 Mar 2017 01:29:43 GMT):
when creating a network model is .cto the only extension one can use to make the file within the model directory?

Hi, I've generated a Java client from the Swagger for the CarAuction-Network. I can use this to post things to the Blockchain but when I try to retrieve items I get exceptions like this: [err] org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "$class" (Class org.acme.vehicle.auction.model.VehicleListing), not marked as ignorable at [Source: sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@5c2788bc; line: 1, column: 165] (through reference chain: org.acme.vehicle.auction.model.VehicleListing["$class"]) The swagger for VehicleListing does not mention $class, but when I poke the API through the Swagger page, all the results contain this $class. For example: [ { "listingId": "83881aee-ef29-4c6d-8ad7-8a2472202ccd", "reservePrice": 1000, "description": "A big green van.", "state": "FOR_SALE", "offers": [], "vehicle": "1234", "$class": "org.acme.vehicle.auction.VehicleListing" } ] Any thoughts? I've tried modifying the generated code, but it's not made any difference so far...

davidkel (Fri, 03 Mar 2017 08:43:27 GMT):
@GrahamCharters $class is mandatory on things like asset creation and transaction submission so without it I am surprised you can post successfully

davidkel (Fri, 03 Mar 2017 08:43:27 GMT):
@GrahamCharters $class is mandatory on things like asset creation and transaction submission so without it I am surprised you can post successfully. Looking at the loopback connector code it will add the $class attribute on the request for you for things like create but I guess it doesn't strip it when data is returned

GrahamCharters (Fri, 03 Mar 2017 08:59:39 GMT):
@davidkel - thanks. I think it either needs to be stripped on the return on it needs to be listed in the Swagger. I'm trying to update the generated code to use the Jackson annotations to ignore it but my JsonIgnoreProperties(ignoreUnknown=true) appears to be being...ignored :(

davidkel (Fri, 03 Mar 2017 09:08:02 GMT):
@GrahamCharters I'm not sure it should be part of the swagger documentation as I think it should match the definition of the model itself and $class is an internal property and as we can manipulate it through the loopback connector it would make sense to strip it out on return. I will create an issue about this. As for now I haven't jackson stuff for so long now I cant remember how you might make a property optional

@davidkel - looks like I'm failing to find a workaround so far (if the field hadn't been called $class I could have hacked the swagger, but that results in a getClass() method being generated that conflicts with Object.getClass()). Perhaps an unfair question, but what would the typical turnaround for a fix be? :S

This sounds like a bug to me. I think we are adding $class on POSTs -- maybe we are not stripping it on GET? @smithsj would know for sure.

If you have created other sample networks that you think would be interesting to share with the community don't hesitate to contact me. The sample networks are imported from this GitHub repo: https://github.com/fabric-composer/sample-networks so we can easily add more.

sstone1 (Fri, 03 Mar 2017 13:08:28 GMT):
@dselman I don't think we should be removing the $class property from the Loopback REST APIs; it's our only way to identify the type of an object. This is important when doing queries on the transaction registry and in the future custom registries which may contain resources of multiple different types.

sstone1 (Fri, 03 Mar 2017 13:11:35 GMT):
@GrahamCharters using the official Swagger Codegen (from Swagger Editor) the generated code can correctly handle GET requests. I believe that works because the generated code is using Gson to handle the JSON data. You seem to be using Jackson? Is this some custom version of Swagger Codegen?

@sstone - Jackson is the default that WAS Liberty uses. If the $class property remains, then shouldn't it be part of the API? I'm not passing it in on at the moment and creating entires works fine.

Hello Community, it is possible to download fabric-composer on Windows7 ?

At present it isn't possible to run on Windows (see http://stackoverflow.com/questions/42009850/fabric-composer-on-windows). We do have an open issue to provide Windows support - but I would expect that Windows 10 would be the minimum version. If you have any thoughts please do add them to the issue mentioned in the SO post.

GeorgSchultz (Fri, 03 Mar 2017 13:56:45 GMT):
Okay, thank you very much for that fast reply! Can you predict a time frame, how long it will need to provide a stable running fabric-composer on Windows10 and Windows7 ?

mbwhite (Fri, 03 Mar 2017 13:59:54 GMT):
At this point I'm afraid not; at present those that do use Windows (myself included) are using Ubuntu in a VM to do development. We don't wish to exclude Windows, but would welcome views on what tools (Poweshell or windows command prompt, Bash in Win10) that people might be using.

GrahamCharters (Fri, 03 Mar 2017 14:11:04 GMT):
I've managed to make some progress by replacing the default serialization in Liberty. My 'ignoring' of $class is now working - clearly not a good answer but it's allowed me to get further. What I've now encoutered is that when I "get" a VehicleListing, the Offers are not of type Offer, they're HashMaps of the properties. This is because the swagger says their type is object: "offers": { "description": "An instance of org.acme.vehicle.auction.Offer", "type": "array", "items": { "type": "object" } },

GrahamCharters (Fri, 03 Mar 2017 14:13:06 GMT):

Hello! wanted to clarify is smart contract logic generated from javascript defined in fabric-composer? or one should add Go or Java implementation of smart-contract to business model?

silliman (Sun, 05 Mar 2017 18:19:51 GMT):
hi @akm4 km4 I'm not on composer dev team so I may be speaking out of turn, but I think what's going on is that fabric-composer is generating the smart contract logic in javascript, but since smart contract is supported in just Go or Java at the moment, that a component called Otto (or a variant of it maybe) is used to convert the javascript to Go inside the chaincode Docker container. IIUC support to run chaincode natively as javascript is on the roadmap.

hi @silliman i was thinking the same, just wanted to clarify if understood correctly

akm4 (Sun, 05 Mar 2017 18:22:42 GMT):
Though that rises another quetion - if i am not satisfied (by any reasons, nothing personal towards Otto devlopers ;) ) with the generated code, can i use my own Go or JS code?

silliman (Sun, 05 Mar 2017 18:30:00 GMT):
@akm4 well in theory you can do whatever you want since the code is open source but when you're talking about changing bits and pieces of artifacts created by higher abstraction layers then you might be on your own in terms of getting support- again, I am not answering as a Composer developer, just as a "civilian"

akm4 (Sun, 05 Mar 2017 18:32:45 GMT):
Yeah, i see! obviously this is the question for the developers of Composer, about their plans and intentions. As a "civilian" i agree with you

davidkel (Sun, 05 Mar 2017 19:21:05 GMT):
@akm4 I think there is a slight misunderstanding here. Otto is an embeddable javascript interpreter written in go so makes it easy to embed into other go code. Composer makes use of otto to interpret the business logic of a business network written in javascript. So go code isn't generated and executed from the javascript

davidkel (Sun, 05 Mar 2017 19:21:05 GMT):
@akm4 Just want to clarify our use of Otto. Otto is an embeddable javascript interpreter written in go so makes it easy to embed into other go code.

sstone1 (Sun, 05 Mar 2017 19:48:00 GMT):
Also FYI, we want to ditch Go + Otto. We are indeed going to look at adding Node.js chaincode support to the base Fabric, at which point we will be 100% pure JavaScript (bar any native modules...)

sstone1 (Sun, 05 Mar 2017 19:48:23 GMT):
Otto has been great for getting us off the ground and up and running, but it has many limitations that are no good for us going forwards.

dselman (Mon, 06 Mar 2017 09:22:46 GMT):
That looks fine -- it just looks like you've not deployed a business network yet using `composer network deploy`. If you run the `npm install` for the quickstart it will start the Fabric and deploy the network.

kosullivan (Mon, 06 Mar 2017 09:28:16 GMT):
@dselman - Thanks for the clarification, the `composer network deploy` fails (details are on http://stackoverflow.com/questions/42583176/getting-started-fabric-composer-on-mac-error-starting-fabric-or-error-deploy). I'm new to fabric so picking my way through the details trying to figure out which actual part isn't working.

dselman (Mon, 06 Mar 2017 09:30:06 GMT):
It seems like you are not following the quickstart instructions. E.g. you don't seem to be running `npm install`. Is that right?

@kosullivan that section of the script is meant to wait for the Fabric to start... if you cancel the script at that point.. and then issue `npm run deployNetwork` does that succeed or fail?

It fails.

But to be honest I'm not familiar enough to recognise any errors in the output yet, or recognise what is normal, what is not

In the case of fabric starting successfully in the foreground - does `npm run deployNetwork` work ?

kosullivan (Mon, 06 Mar 2017 10:13:09 GMT):
Nope, I get same response from `npm run deployNetwork` either way

kosullivan (Mon, 06 Mar 2017 10:14:06 GMT):
Is there some other way to validate that Fabric is running properly ?

mbwhite (Mon, 06 Mar 2017 10:16:45 GMT):
one thing to do is issue `docker logs ` in your case `docker logs 167c9b93d386`

mbwhite (Mon, 06 Mar 2017 10:17:15 GMT):
My current thinking is that perhaps there is a port conflight and/or firewall type issue that is preventing the network connectivity

I'm asking because I'm fairly vested in the CouchDB situation so I'm trying to figure out which way to go now

dselman (Mon, 06 Mar 2017 13:41:44 GMT):
We are working on the port at the moment -- expect to have something (alpha? beta?) within the next few weeks. You can see the code is already going in. Yes, it will use the Apache 2 license.

xixuejia (Mon, 06 Mar 2017 13:42:21 GMT):
Thanks @dselman

MartinMateev (Mon, 06 Mar 2017 13:48:25 GMT):
@Jakeeyturner the reason I'm asking is because it looks to me like the current approach for data modelling is more SQL-like

MartinMateev (Mon, 06 Mar 2017 13:48:41 GMT):
I guess schema-driven

MartinMateev (Mon, 06 Mar 2017 13:49:01 GMT):
my scenario could be implemented by a noSQL DB like CouchDB - basically I keep getting JSON documents

MartinMateev (Mon, 06 Mar 2017 13:49:08 GMT):
that I need to be able to query

MartinMateev (Mon, 06 Mar 2017 13:49:56 GMT):
so I guess the question is how would the CouchDB engine affect the data modelling and how much of the current fabric-composer will be relevant in a few weeks

Jakeeyturner (Mon, 06 Mar 2017 13:52:18 GMT):
I don't understand, what is your scenario?

MartinMateev (Mon, 06 Mar 2017 13:55:37 GMT):
product tracking

MartinMateev (Mon, 06 Mar 2017 13:56:06 GMT):
every 'business operation' generates a JSON document that describes the business step, origin, destination, product serial numbers, etc....

MartinMateev (Mon, 06 Mar 2017 13:56:18 GMT):
so one operation for commissioning products

MartinMateev (Mon, 06 Mar 2017 13:56:21 GMT):
another for shipping,

MartinMateev (Mon, 06 Mar 2017 13:56:26 GMT):
a third for receiving and so on ...

MartinMateev (Mon, 06 Mar 2017 13:56:52 GMT):
since CouchDB supports the /_find API

MartinMateev (Mon, 06 Mar 2017 13:57:06 GMT):
I find it easier to just store all JSON documents in the CouchDB engine as they come in

MartinMateev (Mon, 06 Mar 2017 13:57:24 GMT):
and then use the /_find API to query serial numbers, get origin, provenance, etc...

dselman (Mon, 06 Mar 2017 13:58:18 GMT):
If you model your business domain using Composer, then the framework can perform data validation, Typescript generation for GUIs, REST API generation etc etc. If you just have JSON docs in a NoSQL store you're going to have to reinvent all that yourself.

dselman (Mon, 06 Mar 2017 13:58:38 GMT):
Composer will store the underlying documents in CouchDB

MartinMateev (Mon, 06 Mar 2017 14:02:03 GMT):
ok

MartinMateev (Mon, 06 Mar 2017 14:02:10 GMT):
and what about ACL lists

MartinMateev (Mon, 06 Mar 2017 14:02:27 GMT):
I liked the fact that there were roles and affiliations in the model

MartinMateev (Mon, 06 Mar 2017 14:02:34 GMT):
especially for audit purposes

dselman (Mon, 06 Mar 2017 14:02:36 GMT):
Yes, those as well

MartinMateev (Mon, 06 Mar 2017 14:02:44 GMT):
is this somehow implemented right now in the composer ?

dselman (Mon, 06 Mar 2017 14:02:52 GMT):
YES

It looks like you're trying to submit a transaction which refers to an asset (VehicleListing asset) which doesn't exist

I will reset it and try it again

smithsj (Mon, 06 Mar 2017 14:24:22 GMT):
It looks as though your VehicleListing has managed to get into an odd state there. It seems to have offers for other VehicleListings in its properties

smithsj (Mon, 06 Mar 2017 14:25:35 GMT):
I'm not sure how that has happened - if you can delete that listing and then re-create it with another VehicleListing then that would be great. You can then raise an issue here: https://github.com/fabric-composer/fabric-composer/issues

Jakeeyturner (Mon, 06 Mar 2017 14:28:45 GMT):
@xixuejia How did you get Composer-UI running? Did you follow the instructions here: https://fabric-composer.github.io/start/getting-started-playground.html

Hi, yes I'm using this link

xixuejia (Mon, 06 Mar 2017 14:30:31 GMT):
I'm using `docker-compose up -d` with the docker-compose.yml in that link

xixuejia (Mon, 06 Mar 2017 14:34:56 GMT):
is there a step by step instruction about how to define assets/participants/transactions in composer-ui?

smithsj (Mon, 06 Mar 2017 14:36:28 GMT):
I don't think there's a step by step guide

ayoub (Mon, 06 Mar 2017 14:37:57 GMT):
hi, does composer store locally the chaincode it generates? i.e the chaincode that it deploys when composer deploy is called

dselman (Mon, 06 Mar 2017 14:54:01 GMT):
@xixuejia this may help: https://github.com/fabric-composer/sample-networks/tree/master/packages/CarAuction-Network

dselman (Mon, 06 Mar 2017 14:54:26 GMT):
@ayoub Composer doesn't generate Go code. It executes the JS code inside the Go container using an interpreter.

xixuejia (Mon, 06 Mar 2017 14:58:18 GMT):
Thanks for your instructions!

ardashev120101 (Mon, 06 Mar 2017 14:58:22 GMT):
Hey all - do we have a set of documents or reference materials (or should just one look at the code?) on the topic of doing things by hand in Composer? ie can we change chaincode by hand if we want to?

ardashev120101 (Mon, 06 Mar 2017 14:58:37 GMT):
Sorry for the naive question, haven't used Composer much yet

dselman (Mon, 06 Mar 2017 14:59:28 GMT):
@ardashev120101 "chaincode" in Composer is written as Javascript functions. You can do whatever you need with those functions.

dselman (Mon, 06 Mar 2017 14:59:44 GMT):
You cannot call Go code if that is what you are asking.

xixuejia (Mon, 06 Mar 2017 15:00:22 GMT):
can we use chaincode event in composer? i.e. ChaincodeStubInterface.setEvent()

ayoub (Mon, 06 Mar 2017 15:01:27 GMT):
@dselman thanks for the clarification. when I go inside the container where the code is deployed, I can see some binary data which I was assuming that is the equivalent of ethereum bytecode. is that binery data generated from the js functions?

xixuejia (Mon, 06 Mar 2017 15:01:30 GMT):
so that I would know whether a tx succeed or failed immediately by listening to the event

dselman (Mon, 06 Mar 2017 15:04:19 GMT):
@xixuejia no, we have not exposed this yet through the composer-runtime APIs. We have an open story for this: https://github.com/fabric-composer/fabric-composer/issues/66

dselman (Mon, 06 Mar 2017 15:04:32 GMT):
We will work on this once we finish the port for HL v1

xixuejia (Mon, 06 Mar 2017 15:05:20 GMT):
that's great! thanks for your answer

ayoub (Mon, 06 Mar 2017 15:08:34 GMT):
@dselman, what I am trying to do is use composer to generate the 'chaincode' but for diagnostic be able to manually load the bytecode e.g:

ayoub (Mon, 06 Mar 2017 15:09:02 GMT):
CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=localhost:7051 ./

dselman (Mon, 06 Mar 2017 15:10:21 GMT):
@ayoub as I said, we do not statically compile business network definitions to Go chaincode. We have a generic Go chaincode that interprets the JS functions and metadata in the business network definition. Please refer to StackOverflow (fabric-composer) tag for more details.

ayoub (Mon, 06 Mar 2017 15:15:53 GMT):
thanks @dselman. found the SO reference here: http://stackoverflow.com/questions/42419054/is-it-possible-to-see-the-chain-code-that-is-generated-by-fabric-composer/42421974#42421974

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=2zquWQjrTsZEvgBcz) @dselman Since in Fabric v1.0 CouchDB is optional for the state database, with the default being levelDB, does your statement imply that it would be necessary to choose the CouchDB option if one wants to use Composer, or could Composer be used with the default levelDB (perhaps with limited functionality, e.g.)

dselman (Mon, 06 Mar 2017 16:34:08 GMT):
That's one for @sstone1 or @davidkel who are working on the port.

davidkel (Mon, 06 Mar 2017 16:38:57 GMT):
@silliman composer has no direct dependency on CouchDB, so it would depend on whether fabric itself had restrictions on which persistence technology was used.

Has joined the channel.

silliman (Mon, 06 Mar 2017 16:42:23 GMT):
@davidkel ok thanks! My understanding at this point is that the main benefit of CouchDB over levelDB is that non-key content queries are supported in the former but not the latter. (It's quite possible there are other benefits I'm not aware of)

sstone1 (Mon, 06 Mar 2017 17:00:22 GMT):
@silliman we will likely require the use of CouchDB for complex query support, which we are planning once we get v1.0 support out of the door.

sstone1 (Mon, 06 Mar 2017 17:02:14 GMT):
e.g. "find me all the assets which are blue and owned by someone who lives in the UK"

MartinMateev (Mon, 06 Mar 2017 20:28:25 GMT):
two questions

MartinMateev (Mon, 06 Mar 2017 20:28:32 GMT):
what is the concerto language

MartinMateev (Mon, 06 Mar 2017 20:29:03 GMT):
I didn't see a note on Query capabilities

MartinMateev (Mon, 06 Mar 2017 20:29:03 GMT):
I didn't see a note/example on Query capabilities

MartinMateev (Mon, 06 Mar 2017 20:31:08 GMT):
I assume the current data model is based on the shim.table structures

MartinMateev (Mon, 06 Mar 2017 20:31:23 GMT):
which is part of the key-value store

dselman (Mon, 06 Mar 2017 20:34:10 GMT):
Concerto is the old codename for Composer -- so this refers to the Composer Modeling Language, used to specify the structure and relationships between assets/participants/transactions. Do you have the link where it mentioned Concerto?

dselman (Mon, 06 Mar 2017 20:34:59 GMT):
We have not yet implemented queries. The story for that is here: https://github.com/fabric-composer/fabric-composer/issues/67 We are porting to v1 first and will then evaluate how to map those to CouchDB.

dselman (Mon, 06 Mar 2017 20:35:13 GMT):
Correct, in v0.6 we use tables.

silliman (Mon, 06 Mar 2017 20:48:04 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=xbXgC7LK88WAegGcp) @sstone1 right... I suspect there's some terminology fuzziness and that I've seen "non-key content query, complex query and rich content query" being used to describe the same thing w.r.t. the additional feature of CouchDB compared to levelDB

MartinMateev (Mon, 06 Mar 2017 20:50:12 GMT):
I see 5 occurrences here: https://fabric-composer.github.io/reference/glossary.html

MartinMateev (Mon, 06 Mar 2017 20:51:11 GMT):
well as far as couchDB goes - it should be easier

MartinMateev (Mon, 06 Mar 2017 20:51:23 GMT):
it will assume a schema-free DB engine

MartinMateev (Mon, 06 Mar 2017 20:51:37 GMT):
so clients are creating JSON documents

MartinMateev (Mon, 06 Mar 2017 20:52:02 GMT):
and then using the /_find CouchDB API endpoint to query

MartinMateev (Mon, 06 Mar 2017 20:53:17 GMT):
obviously the query transaction will not be writing anything to the state DB

MartinMateev (Mon, 06 Mar 2017 20:53:50 GMT):
my biggest concern here is that the blockchain itself becomes a wrapper around a CouchDB instance

MartinMateev (Mon, 06 Mar 2017 20:54:31 GMT):
since CouchDB is running as a stand-alone process

MartinMateev (Mon, 06 Mar 2017 20:55:10 GMT):
what happens if someone hacks into a node and then hacks into the CouchDB server

MartinMateev (Mon, 06 Mar 2017 20:55:10 GMT):
that practically exposes the entire world state

MartinMateev (Mon, 06 Mar 2017 20:56:08 GMT):
and defeats the purpose of running a blockchain

MartinMateev (Mon, 06 Mar 2017 20:56:08 GMT):
and defeats the purpose of running a blockchain (to a certain extent)

jdockter (Mon, 06 Mar 2017 22:00:29 GMT):
@dselman when would you want to model an asset of assets vs an asset of transactions? For example the car auction of VehicleListing had Offer[] which was a transaction to add to asset....could VehicleListing just have a relationship to an array of Offer assets? Is there something tracked or available via query that I should be considering when I create my model?

dselman (Mon, 06 Mar 2017 22:03:59 GMT):
One factor: one is "owned" by an asset, so deleting the asset, deletes all the contained assets/transactions while the other references them (so deleting the parent does not delete the referenced assets/transactions).

dselman (Mon, 06 Mar 2017 22:04:34 GMT):
Assets that are not stored in a registry cannot be referenced by other assets or transactions.

dselman (Mon, 06 Mar 2017 22:04:34 GMT):
Assets that are not stored in a registry (top-level) cannot be referenced by other assets or transactions.

dselman (Mon, 06 Mar 2017 22:05:52 GMT):
Assets in a registry can have their own lifecycle transactions quite easily. E.g. an Order asset may have a Purchase transaction with a relationship to the Order.

jdockter (Mon, 06 Mar 2017 22:16:28 GMT):
Think I follow your 1st and 3rd statements...but on the 2nd...when is an Asset not stored in a registry?

jdockter (Mon, 06 Mar 2017 22:23:11 GMT):
And back to the VechicleListing...if you wanted to remove an Offer from a VechicleListing could I do that by updating the VechileListing asset or would I have to have another transaction to do that? Seems like I would be able to send in a REST update to the asset easy enough changing the whole structure of it....I think

dselman (Mon, 06 Mar 2017 22:39:55 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=RyFj75ZoMyFeQviSd) @jdockter When it is embedded in another asset for example. We may prevents that in the future, so I wouldn't do that.

dselman (Mon, 06 Mar 2017 22:41:08 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=pF3Et2cjg8Mq6uj6u) @jdockter either would work. The TX may be faster (partial updates) and is more flexible in terms of running functions on the server side when an update occurs.

klorenz (Tue, 07 Mar 2017 01:23:17 GMT):
@dselman - For the car auction; if the Offer (transaction) was a complex bid object (versus simple Double of bidPrice). For purposes of discussion lets say the complex object was a List of bids with a given bid say having a bidPrice and a bidDate. How would you suggest modeling that List of builds within the Offer transaction?

klorenz (Tue, 07 Mar 2017 01:33:15 GMT):
Intention that a given User performing the Offer transaction at a specific moment in time is entering some type of complex object. Is something where the Bid could be a Concept (bidPrice and bidDate), and the Offer transaction would have a list of Bids? Or maybe Bid is a concept that has a list of BidDetails (bidPrice & bidDate) concepts... so the Offer transaction has a Bid which it a list of BidDetails?

dselman (Tue, 07 Mar 2017 08:04:28 GMT):
@klorenz I think I'd make Bid a concept and then make Offer a transaction, something like: ``` concept Bid { o Double bidPrice o DateTime bidDate } transaction Offer identified by transactionId { o String transactionId o Bid[] bids } ```

MartinMateev (Tue, 07 Mar 2017 08:26:03 GMT):
can anyone comment on the security risks associated with running a stand-alone CouchDB instance

MartinMateev (Tue, 07 Mar 2017 08:26:25 GMT):
is it possible to lock down access to the DB engine so that read/write access can happen ONLY via the blockchain mechanisms?

dselman (Tue, 07 Mar 2017 08:52:20 GMT):
@MartinMateev that sounds like a question for #fabric

dselman (Tue, 07 Mar 2017 09:47:07 GMT):
@sstone1 is working on getting those removed from the Swagger -- because transactions are append-only to the transaction registry.

uber.twin (Tue, 07 Mar 2017 15:38:47 GMT):
hi, not sure I got this right but it seems to me that the blockchain data can be modified by the chaincode ran in an external nodejs client or by the chaincode deployed with the network and executed in a transaction processor function context by a blockchain peer

uber.twin (Tue, 07 Mar 2017 15:40:27 GMT):
if this is true, what is the reason of making it possible to have the chaincode API available in a client environment, I thought only the network peers are suppose to run it

sstone1 (Tue, 07 Mar 2017 15:47:24 GMT):
@uber.twin I think you are referring to our ability to run our runtime and the JavaScript transaction processor functions outside of a Blockchain?

sstone1 (Tue, 07 Mar 2017 15:48:41 GMT):
When you do this, we are simulating a blockchain in Node.js. There is no interaction with a real blockchain.

sstone1 (Tue, 07 Mar 2017 15:48:48 GMT):
There are two reasons for this.

sstone1 (Tue, 07 Mar 2017 15:50:15 GMT):
1) It enables us to run the runtime and JavaScript transaction processor functions in a web browser, allowing users to learn Fabric Composer and rapidly model/test their business network from our web playground without having to stand up a real Hyperledger Fabric network.

sstone1 (Tue, 07 Mar 2017 15:50:28 GMT):
(http://fabric-composer.mybluemix.net/editor if you haven't seen it)

sstone1 (Tue, 07 Mar 2017 15:51:07 GMT):
2) It enables us to run the runtime and JavaScript transaction processor functions in Node.js. This allows users to write and automate unit tests for a business network using any standard JavaScript unit testing tools, for example Mocha and Chai.

sstone1 (Tue, 07 Mar 2017 15:51:52 GMT):
(https://github.com/fabric-composer/sample-networks/blob/master/packages/Sample-Network/test/Sample.js as an example)

sstone1 (Tue, 07 Mar 2017 15:52:49 GMT):
When you are running with a real Hyperledger Fabric instance, our runtime and the JavaScript transaction processor functions run on the blockchain and can modify the blockchain data - but that's the only place that blockchain data can be modified.

uber.twin (Tue, 07 Mar 2017 15:55:10 GMT):
I was experimenting with the Getting Started setup and the routines in the landRegistry.js seem to populate the blockchain data and update it too

uber.twin (Tue, 07 Mar 2017 15:55:37 GMT):
and those seem to be ran in an external nodejs env

sstone1 (Tue, 07 Mar 2017 15:55:54 GMT):
This file?

sstone1 (Tue, 07 Mar 2017 15:55:55 GMT):
https://github.com/fabric-composer/sample-applications/blob/master/packages/getting-started/lib/landRegistry.js

uber.twin (Tue, 07 Mar 2017 15:56:21 GMT):
yes

sstone1 (Tue, 07 Mar 2017 15:56:58 GMT):
That code is using our client APIs to perform CRUD operations on assets/participants and submit transactions to a deployed business network.

sstone1 (Tue, 07 Mar 2017 15:57:23 GMT):
All CRUD operations result in Hyperledger Fabric transactions that invoke our runtime on the blockchain.

uber.twin (Tue, 07 Mar 2017 16:00:06 GMT):
than isn't it the same API used to write transaction processor function?

sstone1 (Tue, 07 Mar 2017 16:03:48 GMT):
We have a client API and a runtime API. They are intentionally very similar ;)

uber.twin (Tue, 07 Mar 2017 16:06:48 GMT):
extremely powerful Client API:)

uber.twin (Tue, 07 Mar 2017 16:07:51 GMT):
ok, it seemed strange because other blockchain implementation appear to expose only a RPC style interface for the clients

uber.twin (Tue, 07 Mar 2017 16:09:58 GMT):
thank you for clarifying it

sstone1 (Tue, 07 Mar 2017 16:10:41 GMT):
The client API provides a layer of abstraction on top of the Hyperledger Fabric RPC style APIs; the client API is just calling the `hfc` library under the covers.

sstone1 (Tue, 07 Mar 2017 16:10:42 GMT):
No problem

uber.twin (Tue, 07 Mar 2017 16:12:59 GMT):
sure, I thought the code gets submitted to peers eventually

uber.twin (Tue, 07 Mar 2017 16:19:32 GMT):
is there another, possibly standard setup, apart from the Getting Started environment, to be used for a fresh project?

sstone1 (Tue, 07 Mar 2017 16:22:32 GMT):
We don't currently have a `yo` generator for a skeleton business network project, and we probably should.

sstone1 (Tue, 07 Mar 2017 16:22:41 GMT):
The simplest business network definition project is here: https://github.com/fabric-composer/sample-networks/tree/master/packages/Sample-Network

sstone1 (Tue, 07 Mar 2017 16:23:21 GMT):
It does not have any of the automation that the Getting Started project has for standing up Hyperledger Fabric, but I think once you move past Getting Started you really need to be able to stand up your own Hyperledger Fabric instance.

sstone1 (Tue, 07 Mar 2017 16:23:42 GMT):
The Getting Started project also makes use of the Composer CLI for deploying business networks: `composer network deploy`

sstone1 (Tue, 07 Mar 2017 16:24:36 GMT):
Also, you might like to try standing up the Composer UI locally for developing and testing a business network. Unlike the version on Bluemix, a local version can connect to a real Hyperledger Fabric instance.

sstone1 (Tue, 07 Mar 2017 16:24:41 GMT):
The instructions for that are here: https://fabric-composer.github.io/start/getting-started-playground.html

sstone1 (Tue, 07 Mar 2017 16:25:03 GMT):
The docker-compose.yml on that page will create a v0.6 fabric for the UI to use.

uber.twin (Tue, 07 Mar 2017 16:28:29 GMT):
ok, I'll look at it

uber.twin (Tue, 07 Mar 2017 16:29:28 GMT):
Composer UI runs the same Client API as the Getting Started app or is based on a RPC interface?

mhalder (Tue, 07 Mar 2017 16:37:44 GMT):
Has joined the channel.

sstone1 (Tue, 07 Mar 2017 16:42:54 GMT):
Composer UI uses the `composer-client` APIs under the covers

uber.twin (Tue, 07 Mar 2017 16:44:50 GMT):
so the only way to interface with the fabric composer network is a nodejs env, right?

sstone1 (Tue, 07 Mar 2017 16:45:49 GMT):
Nope, you can use the REST APIs as an alternative to the Node.js APIs.

uber.twin (Tue, 07 Mar 2017 16:47:36 GMT):
could you please give me a reference in this direction?

sstone1 (Tue, 07 Mar 2017 16:47:53 GMT):
https://fabric-composer.github.io/start/getting-started-rest-api.html

uber.twin (Tue, 07 Mar 2017 16:51:22 GMT):
but this REST API is still intermeiated by a nodejs server, isn't it?

uber.twin (Tue, 07 Mar 2017 16:52:08 GMT):
*intermediated

uber.twin (Tue, 07 Mar 2017 16:52:36 GMT):
or is it provider directly, by a network peer?

uber.twin (Tue, 07 Mar 2017 16:53:53 GMT):
*provided

sstone1 (Tue, 07 Mar 2017 16:54:06 GMT):
Correct, the REST API uses the LoopBack framework which is an open-source Node.js application for generating REST APIs from backend systems such as databases (and blockchains!)

uber.twin (Tue, 07 Mar 2017 16:59:41 GMT):
ok, thank you again:)

@pards the data is currently stored in the world state on the blockchain

pards (Tue, 07 Mar 2017 21:10:22 GMT):
the source code, too?

sstone1 (Tue, 07 Mar 2017 21:10:27 GMT):
yep

sstone1 (Tue, 07 Mar 2017 21:10:41 GMT):
The new playground experience has an import/export feature, so you'll be able to get the source code out of the browser.

sstone1 (Tue, 07 Mar 2017 21:11:01 GMT):
We also need to get the web browser to persist the source somewhere other than the blockchain ;)

pards (Tue, 07 Mar 2017 21:11:04 GMT):
Ok, but to use Git I'll need to build the code in Atom

jdockter (Tue, 07 Mar 2017 22:18:38 GMT):
guess that same would apply for a REST API POST for a specific asset...or I guess even a participant as that is also a table in the world state

dselman (Tue, 07 Mar 2017 22:55:29 GMT):
correct

jdockter (Tue, 07 Mar 2017 22:55:41 GMT):
Another set of questions...when do relationships get enforced, ie transaction only? and why would I want a relationship to go both ways, ie asset 1 has a relationship to asset 2, and asset 2 has a relationship back to asset 1?

dselman (Tue, 07 Mar 2017 22:55:55 GMT):
You can use the Hyperledger Fabric Explorer to see the blockchain transactions

jdockter (Tue, 07 Mar 2017 22:56:40 GMT):
yeah I got it up.....I see all kinds of blocks...but wasn't sure if each was it's own transaction

jdockter (Tue, 07 Mar 2017 22:57:25 GMT):
seems like each block has 1 transaction

dselman (Tue, 07 Mar 2017 22:57:32 GMT):
If you look at the contents you'll see Base64 encoded JSON for the assets you are creating/updating or the transactions you are submitting

dselman (Tue, 07 Mar 2017 22:59:01 GMT):
Composer doesn't enforce referential integrity for relationships per se -- all it does it attempt to resolve the relationships for an incoming transaction (so that the JS code doesn't need to resolve manually).

jdockter (Tue, 07 Mar 2017 23:08:37 GMT):
For some reason I thought that a block could have more than one transaction logged against it

dselman (Tue, 07 Mar 2017 23:21:36 GMT):
It can -- I think it's a Fabric config property.

sstone1 (Tue, 07 Mar 2017 23:54:40 GMT):
Yeah; if you submit enough Composer transactions in a short period of time, they'll be batched up into blocks.

sstone1 (Tue, 07 Mar 2017 23:54:50 GMT):
Click quicker @jdockter ;)

jdockter (Tue, 07 Mar 2017 23:55:11 GMT):
ha okay

jdockter (Tue, 07 Mar 2017 23:59:13 GMT):
So maybe a dumb question...but if a REST APIs creates blockchain transactions via a put to the world state...then why would I need a composer transaction?

jdockter (Tue, 07 Mar 2017 23:59:33 GMT):
REST APIs for assets that is

dselman (Wed, 08 Mar 2017 00:06:10 GMT):
Transactions let you run logic on the ledger... logic that is shared across all business network participants. This is much more powerful than clients just performing CRUD operations.

dselman (Wed, 08 Mar 2017 00:08:13 GMT):
e.g. see the Car Auction example when it processes the CloseBidding transaction.

jdockter (Wed, 08 Mar 2017 00:08:58 GMT):
yup okay, thanks

sstone1 (Wed, 08 Mar 2017 12:50:00 GMT):
I think if you try a HLF register again, you'll get the same secret back, but if you try that via Composer we'll throw an error as the identity has already been issued to a participant.

dselman (Wed, 08 Mar 2017 14:39:30 GMT):
@pards we support 3 different modes of operation, depending on DevOps sophisticated and need for reuse: 1. simply put the models under the modles/ folder and JS functions under lib/ inside the application folder. 2. Move the business network into its own npm module and publish to npm for consumption by applications. 3. Move the model(s) into their own npm modules for consumption by business networks.

You'll see a mix of these approaches I think across our samples

dselman (Wed, 08 Mar 2017 14:41:36 GMT):
(1) is quick and dirty frankly -- and binds the business network definition to a single consuming application. (2) allows the business network definition to be shared across multiple apps. (3) Takes it a step further and allows models to be shared across business networks.

pards (Wed, 08 Mar 2017 14:43:28 GMT):
And the Yeoman generator creates and _application_, not a _business network definition_, right?

is there an example showing how to add a new participant, similar to the WebAppAdmin?

jdockter (Wed, 08 Mar 2017 14:49:26 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=MuRuKP4vFtFJWAWyg) @pards it seems like the generator package.json assumes it's published...many built in scripts in that file...so might want to just customize to your dev environment...the generated index.js has lots of goodness in it :)

jdockter (Wed, 08 Mar 2017 14:49:56 GMT):

@jdockter yes, thank you

uber.twin (Wed, 08 Mar 2017 15:07:03 GMT):
can't see how the WebAppAdmin participant was added though in the getting started application

uber.twin (Wed, 08 Mar 2017 15:07:43 GMT):
is this some kind of preexisting root participant?

jdockter (Wed, 08 Mar 2017 15:09:46 GMT):
Yes, it's my understanding it's pre-registered in the member services of HLF

uber.twin (Wed, 08 Mar 2017 15:19:16 GMT):
are the fabric-composer images for the regular peers and the membership validator peer, just the same as their corresponding counterpart from a basic fabric runtime?

uber.twin (Wed, 08 Mar 2017 15:21:24 GMT):
or the fabric-composer peers run extra layers of the protocol?

uber.twin (Wed, 08 Mar 2017 15:29:39 GMT):
and if they are not exactly the same is there a reference regarding how to build each type of fabric-composer peer?

dselman (Wed, 08 Mar 2017 15:34:35 GMT):

the getting started app doesn't seem to declare a dedicated orderer peer; is this because it isn't necessary for a one peer network or the ordering service is integrated within the regular peer?

Jakeeyturner (Wed, 08 Mar 2017 15:49:30 GMT):
Remembering that currently Fabric Composer is based upon Hyperledger Fabric v0.6, our getting started will bring up a single peer and memberservice

Jakeeyturner (Wed, 08 Mar 2017 15:49:40 GMT):
So yes, the ordering service is part of this one peer

uber.twin (Wed, 08 Mar 2017 15:52:34 GMT):

@tarima are you wondering how you get the actual error, rather than the "timed out" error?

sstone1 (Thu, 09 Mar 2017 08:25:19 GMT):
In Hyperledger Fabric v0.6 you cannot get the actual error from the chaincode, all you get is "timed out waiting for transaction". This has been fixed in Hyperledger Fabric v1.0, and we are currently working on support for that in Fabric Composer.

@aaron_z7 if you run `docker ps -a` you should see 3 running docker containers. One of the docker contains will be the chaincode container (where the Composer runtime is executing your logic). It has a generated name something like: `dev-vp0-4968dea9e3a69670235d9283859801ab5df6f18398f15711d6f5426123955f9f` Look for its container id, and then run `docker logs `

dselman (Thu, 09 Mar 2017 12:28:14 GMT):
You can follow the logs using `docker logs -f`

sstone1 (Thu, 09 Mar 2017 15:01:34 GMT):
@pards but you can generate client SDKs in a wide range of languages from the `composer-rest-server` using something called `swagger-codegen` if you want :)

question...so for participants...the details of an individual user, is that really something we want on the blockchain...or do we just want to user participant as a role which can be leveraged in the ACL...and then the CA has the actual identity and secret , with ECert and TCerts under the covers?

Hi - after running fabric (via `npm install` in getting-started folder), what should I get when I open 127.0.0.1:7050 ?

kosullivan (Thu, 09 Mar 2017 19:05:57 GMT):
I get this: ```$ curl 127.0.0.1:7050 {"Error":"Openchain endpoint not found."}```

@mohamoud.egal the error states that you haven't deployed a business network. Are you following the "Generating a REST API" page? If so, you must run through the previous tutorial: https://fabric-composer.github.io/start/getting-started-cmd-line.html

We plan to cut a 0.5.0 release tomorrow (Friday). We have modified the grammar for ACLs (breaking change) -- the sample networks have already been updated to reflect the new grammar.

dselman (Thu, 09 Mar 2017 23:06:18 GMT):
Here is an example: https://github.com/fabric-composer/sample-networks/blob/master/packages/CarAuction-Network/permissions.acl

dselman (Thu, 09 Mar 2017 23:06:54 GMT):
We believe the new grammar will be easier to edit by hand, easier to understand, and more aligned with the ACL editor that we will be developing in the coming weeks.

@pospi there has never been a `latest` tag for `hyperledger/fabric-baseimage` - the reason is that the base image needs to be matched to the version & architecture of the peer. All of the Composer docs/scripts that create Fabric instances run the following commands: ` `` docker pull hyperledger/fabric-baseimage:x86_64-0.1.0 docker tag hyperledger/fabric-baseimage:x86_64-0.1.0 hyperledger/fabric-baseimage:latest ```

hi, sorry to bother you with setup issues, I realize this is a nodejs related confusion I got somehow I managed to break my dev env such as the "composer archive create" didn't work anymore because it could not resolve the "digitalproperty-network" module anymore I tried to re-clone the sample-applications repository and start fresh but I was getting the same error it started to work again after re-runing "npm install -g composer-cli" could anybody clarify for me what happened, what could be the reason for "composer-cli" stop working?

dselman (Fri, 10 Mar 2017 09:58:42 GMT):
Hard to say... Obviously it would stop working if you ran `npm uninstall composer-cli -g` or if you deleted the install directory for globally installed npm modules.

uber.twin (Fri, 10 Mar 2017 10:31:30 GMT):
thanks, you got me to finally realize what happened: before installing the fabric-composer first time, I had a noderc "prefix" property declaration: prefix=/home/pg/.node_modules_global than I removed it, so I guess all packages installed at that location are not available anymore

uber.twin (Fri, 10 Mar 2017 10:46:53 GMT):
talking about modules location, is it required that all local modules to be found under the node_modules directory? it would be handy to be able to have the modules implementing the application functionality separated of the multitude of dependency modules

uber.twin (Fri, 10 Mar 2017 15:15:21 GMT):
I created them manually, by duplicating the stated existing modules( digitalproperty-model and digitalproperty-network) and than editing the package.json this is my first encounter with node so I don't know what I am doing really

uber.twin (Fri, 10 Mar 2017 15:16:13 GMT):
do this newly added modules need to be registered with the npm registry?

uber.twin (Fri, 10 Mar 2017 15:17:06 GMT):
in order for composer to be able to resolve them

mbwhite (Fri, 10 Mar 2017 15:21:10 GMT):
They don't need to be added to the npm registry; as you are inside your new business network, you can use the following command. `composer archive create --sourceName . --sourceType dir --archiveFile myCoreNetwork.bna`

mbwhite (Fri, 10 Mar 2017 15:21:56 GMT):
do you have the model and network in a different node projects?

dselman (Fri, 10 Mar 2017 18:19:12 GMT):
Composer is flexible enough to handle both. It's really up to the business network to decide whether they want to use logical roles or actually certificates that tie to a physical person.

We have released version v0.5.0 of Fabric Composer :beers: You can check out the release notes here: https://github.com/fabric-composer/fabric-composer/releases/tag/v0.5.0 There has been a lot of work towards our new Composer Playground experience, which you can preview here: http://fabric-composer-next.mybluemix.net We've made some updates to our REST API generation, to implement missing functionality and reduce the confusingly large number of REST API methods. We've redesigned the ACL language so it's much easier to read and understand, and we have changed all our samples to reflect this. We've published Atom and VSCode plugins to their respective marketplaces for syntax highlighting, validation, etc. We've made some great progress towards Hyperledger Fabric v1.0 support, and we're getting close to getting all our system tests passing on v1.0. Thanks to the team for all of their hard work, and thanks to the community for all of your valuable feedback - have a great weekend everybody!

sstone1 (Fri, 10 Mar 2017 18:55:05 GMT):
@mohamoud.egal OK I think I see the problem. You only have `property-network` deployed, but the REST API page relies on `digitalproperty-network` being deployed. I think you're just following the tutorials under "Getting Started" in order right?

sstone1 (Fri, 10 Mar 2017 18:56:03 GMT):
You can follow the REST API page if you skip the `npm run listAssets` step (which relies on `digitalproperty-network`) and jump straight to the `composer-rest-server` steps. You must put in the correct business network identifier of `property-network` when asked though.

sstone1 (Fri, 10 Mar 2017 18:56:23 GMT):
We'll look at getting the docs cleaned up for that

mohamoud.egal (Fri, 10 Mar 2017 19:01:32 GMT):
@sstone1 ok. Does it matter what directory I start the composer-rest-server command?

mohamoud.egal (Fri, 10 Mar 2017 19:01:42 GMT):
should I be in the property-network folder?

sstone1 (Fri, 10 Mar 2017 19:02:24 GMT):
No, it shouldn't matter - the `composer-rest-server` uses the information in the connection profile to talk to the deployed business network.

jdockter (Fri, 10 Mar 2017 19:09:08 GMT):
@sstone1 so with the new playground...I see we can import a bna...do we need to recreate the bna with different ACL format?

getting 'Error: Expected "rule", comment, end of line or whitespace but "D" found. Line 4 column 1' error?

@mohamoud.egal as per my earlier message, we released 0.5.0 today. This is incompatible with the deployed version you have, 0.4.5. You either need to upgrade everything to 0.5.0 and redeploy the business network, or install an older version of `composer-rest-server` - the latter might be quicker (`npm install -g composer-rest-server@0.4.5`)

mohamoud.egal (Fri, 10 Mar 2017 23:04:41 GMT):

@conroydave this is probably because you've used it before and have some incompatible data in local storage (https://github.com/fabric-composer/fabric-composer/issues/304)

dselman (Sat, 11 Mar 2017 09:22:39 GMT):
If you are on FireFox you should open the Web Console and then type `localStorage.clear()`

dselman (Sat, 11 Mar 2017 09:22:45 GMT):
And reload the page

dselman (Sat, 11 Mar 2017 09:23:17 GMT):
We're working on detecting this automatically and recovering

conroydave (Sat, 11 Mar 2017 09:25:52 GMT):
yep cleared it and now it loads

dselman (Sat, 11 Mar 2017 09:31:06 GMT):
:thumbsup:

conroydave (Sat, 11 Mar 2017 09:37:36 GMT):
ive done the rm rf /node modules and rebuilt

that fixed it

no, it was in 0.4.5 as well

conroydave (Sat, 11 Mar 2017 10:44:19 GMT):
got the app generator going. seems like i might still be some dependency issue that i need to fix as one of the first lines after 'npm start' in the app directory also has the version missmatch error

after updating the package.json in the app dir for composer-client to .0.5, rm-rf the node_modules dir, reinstalled.. now it works

conroydave (Sat, 11 Mar 2017 10:56:01 GMT):
not sure why that was generated with the .4.5 version though

conroydave (Sat, 11 Mar 2017 10:56:06 GMT):
originally

dselman (Sat, 11 Mar 2017 11:23:50 GMT):
Thanks again @conroydave -- the changes to the templates for Yeoman are in (updating the dependencies to 0.5.0) and are making their way through the build process now.

conroydave (Sat, 11 Mar 2017 11:27:51 GMT):
cool. so is the idea now that i could take any sample network from the sample-network repo and deploy it just as easy the digitalproperty network. Using composer and its tools to automatically handle all of the api and and app generation

dselman (Sat, 11 Mar 2017 11:36:31 GMT):
correct

dselman (Sat, 11 Mar 2017 11:37:46 GMT):
the generated app is obviously just a starting point, but it removes a bunch of time consuming bootsrapping discussions.

Hi, I try to create a new business network, following the example in https://fabric-composer.github.io/start/getting-started-coding-bnd.html . However, I get an error when I try to call a transaction (via REST API) that is supposed to call the defined JavaScript function. In my version of transaction, the error log says that that *returAssetRegistry* is not found. Where should the *returAssetRegistry* function be defined? And it seems like a typo anyway... ```function onRegisterPropertyForSale(propertyForSale) { console.log('### onRegisterPropertyForSale ' + propertyForSale.toString()); propertyForSale.title.forSale = true; returAssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) { return result.update(propertyForSale.title); } ); }```

annbnn (Mon, 13 Mar 2017 08:46:49 GMT):
How to solve it please ?

sstone1 (Mon, 13 Mar 2017 08:54:56 GMT):
@annbnn you must deploy a business network using 0.5.x, the 0.4.x chaincode and 0.5.x clients are incompatible

bravera (Mon, 13 Mar 2017 08:56:23 GMT):
I've got composer working with a deployed business network and am comfortable with how to add new transactions through the cto and chaincode, but how do i go about preventing update and delete actions being performed on assets? At the moment, with a loopback connector running I seem to be free to delete and update assets but i want to make sure these actions can only be done through deployed chaincode

sstone1 (Mon, 13 Mar 2017 08:59:26 GMT):
@bravera have you set up an ACL file with the rules about who can do what in the business network?

sstone1 (Mon, 13 Mar 2017 09:00:05 GMT):
The REST server runs as a particular participant on the business network; you have to give it an enrollment ID/secret to connect.

sstone1 (Mon, 13 Mar 2017 09:00:24 GMT):
Access control is based on the current participant, so all REST API calls to the REST server will run as the specified participant.

sstone1 (Mon, 13 Mar 2017 09:00:48 GMT):
Note that if you use admin / WebAppAdmin to talk to the business network, ACL rules aren't enforced.

sstone1 (Mon, 13 Mar 2017 09:01:57 GMT):
We are looking at allowing REST API clients to authenticate to the REST server to be able to pass their own identities, and also locking down the business network so that ACL rules are always enforced.

bravera (Mon, 13 Mar 2017 09:21:02 GMT):
@sstone1 so the REST server can only run as one participant at the moment?

sstone1 (Mon, 13 Mar 2017 09:21:13 GMT):
correct

bravera (Mon, 13 Mar 2017 09:24:46 GMT):
From your final sentence do I take it that at the moment it is possible to circumvent the ACL rules, or are you referring to the fact that WebAppAdmin isn't subject to the ACL rules?

sstone1 (Mon, 13 Mar 2017 09:38:56 GMT):
admin / WebAppAdmin aren't subject to the ACL rules at present

uber.twin (Mon, 13 Mar 2017 10:11:01 GMT):
hi, is this page all the existing documentation on the runtime API? https://fabric-composer.github.io/jsdoc/module-composer-runtime.html#getFactory__anchor

uber.twin (Mon, 13 Mar 2017 10:19:54 GMT):
I was trying to compile a new network with "composer archive create" and I was getting "Cannot read property 'name' of null" It seems the problem was the "@param" annotation. e.g. "@param {com.myNetwork.MyInstruction}". Apparently it needed an extra string at the end of it: "@param {com.myNetwork.MyInstruction} instruction" Is there a complete specification for all the annotations?

annbnn (Mon, 13 Mar 2017 10:21:32 GMT):
@sstone1 Thank you. How to move from 0.4.x to 0.5.x chaincode ?

sstone1 (Mon, 13 Mar 2017 10:22:21 GMT):
@annbnn you need to install the latest version of the CLI; `npm install -g composer-cli` (might need to put sudo in front of that depending on your system)

sstone1 (Mon, 13 Mar 2017 10:22:32 GMT):
Did you deploy the business network using the getting started guide?

annbnn (Mon, 13 Mar 2017 10:22:38 GMT):
I did it

annbnn (Mon, 13 Mar 2017 10:22:45 GMT):
sstone1.

sstone1 (Mon, 13 Mar 2017 10:23:31 GMT):
@uber.twin in that case, it's defined by the JSDoc standard (http://usejsdoc.org/tags-param.html), but I think that is a bug that we fixed in the latest versions.

sstone1 (Mon, 13 Mar 2017 10:24:07 GMT):
@annbnn if you followed the getting started guide then you need to pull down the latest changes to getting started (either delete the old sample-applications project and git clone it again, or do a git pull)

sstone1 (Mon, 13 Mar 2017 10:24:39 GMT):
Once you've got the latest changes down you need to delete the node_modules directory inside the getting-started folder and re-run npm install

annbnn (Mon, 13 Mar 2017 10:25:24 GMT):
Oh I see

I got that output.

sstone1 (Mon, 13 Mar 2017 11:21:43 GMT):
did you pull the latest changes, delete the node_modules folder, and re-run npm install?

sstone1 (Mon, 13 Mar 2017 11:22:18 GMT):
the package.json in the getting started directory should have the same content as this https://github.com/fabric-composer/sample-applications/blob/master/packages/getting-started/package.json

annbnn (Mon, 13 Mar 2017 11:56:56 GMT):

annbnn (Mon, 13 Mar 2017 12:07:18 GMT):
@sstone1 So I should create a new Business definition in order to genereate the REST API

annbnn (Mon, 13 Mar 2017 12:07:19 GMT):
right ?

sstone1 (Mon, 13 Mar 2017 12:09:52 GMT):
That still doesn't look right; you have a mix of 0.4.5 and 0.5.0 modules

sstone1 (Mon, 13 Mar 2017 12:10:09 GMT):
Can you run `grep composer package.json` in the getting started directory?

sstone1 (Mon, 13 Mar 2017 12:13:33 GMT):
you need to run `git pull`

sstone1 (Mon, 13 Mar 2017 12:13:47 GMT):
or delete it and run another `git clone`

annbnn (Mon, 13 Mar 2017 12:14:49 GMT):
deleting what ?

sstone1 (Mon, 13 Mar 2017 12:15:06 GMT):
delete the cloned `sample-applications` repository

annbnn (Mon, 13 Mar 2017 12:15:12 GMT):
Okay

sstone1 (Mon, 13 Mar 2017 12:15:17 GMT):
it does not have the latest changes in it, so it does not pick up the 0.5.x modules

annbnn (Mon, 13 Mar 2017 12:16:01 GMT):
I deleted the sample-applications repo

annbnn (Mon, 13 Mar 2017 12:16:06 GMT):
and made git pull

sstone1 (Mon, 13 Mar 2017 12:17:07 GMT):
OK, so now you need to rerun the git clone instructions from the docs

annbnn (Mon, 13 Mar 2017 12:17:44 GMT):
npm install -g composer-cli

annbnn (Mon, 13 Mar 2017 12:17:54 GMT):
git clone https://github.com/fabric-composer/sample-applications.git

annbnn (Mon, 13 Mar 2017 12:17:59 GMT):
Okay

sstone1 (Mon, 13 Mar 2017 12:18:05 GMT):
yep

sstone1 (Mon, 13 Mar 2017 12:18:31 GMT):
then re-run the `npm install` step which will deploy a 0.5.x chaincode

mbwhite (Mon, 13 Mar 2017 12:20:34 GMT):
@annbnn might be worth taking at look at https://www.youtube.com/watch?v=pEHBIfb_iqc - shows the getting started.

Something to look into

sstone1 (Mon, 13 Mar 2017 15:34:21 GMT):
@bravera correct, it is the participant that the REST server uses to discover the network, and service all REST requests.

sstone1 (Mon, 13 Mar 2017 15:35:03 GMT):
In the future I imagine the REST server will only need a participant with very restricted permissions in order to discover the network, and then REST clients will identify themselves as separate participants

Can the `getting-started` application be configured to interact with a Fabric that has been stood up separately (and not running on `localhost`)?

dselman (Tue, 14 Mar 2017 14:51:26 GMT):
yes -- edit the connection profile under `~/.composer-connection-profiles/defaultProfile/connection.json` -- you'll find the Peer URLs etc in there.

dselman (Tue, 14 Mar 2017 14:52:48 GMT):
You can create a new connection profile for your remote machine by cloning defaultProfile and naming it something else, then run a `composer network deploy` referencing the name of your profile

dselman (Tue, 14 Mar 2017 14:53:46 GMT):
All the Composer CLIs and APIs use a connection profile name to specify how to reach a network.

mikezaccardo (Tue, 14 Mar 2017 14:58:46 GMT):
Thanks @dselman -- when does that file get created? Looking at the code, all I see is `rm -rf ~/.composer-connection-profiles/*` but no creation

dselman (Tue, 14 Mar 2017 15:00:36 GMT):
composer-cli will create the defaultProfile if it does not exist, assuming your are running HLF locally. You can create your own manually if you wish.

dselman (Tue, 14 Mar 2017 15:01:24 GMT):
``Daniels-MacBook-Pro:fabric-composer dselman$ cat ~/.composer-connection-profiles/test/connection.json { "type": "hfc", "keyValStore": "/tmp/keyValStore", "membershipServicesURL": "grpc://membersrvc", "peerURL": "grpc://vp0", "eventHubURL": "grpc://vp1" ``

However, the transaction seems to fail if sending in an updated json for that same Asset (using same identified by field). [fyi... this works currently via the rest server using Put-by-ID transaction.] So I tried a similar IIB message flow with operation of 'Update' however that does not seem to get submitted either (not seeing any transaction on the blockchain). Any suggestion on how loopback-connector is intended to work for submitting updated Assets... or if I'm doing something incorrect with my test/setup?

sstone1 (Tue, 14 Mar 2017 15:54:30 GMT):
@klorenz we haven't done an 'Update' from IIB to Blockchain yet; let me look into it...

dselman (Tue, 14 Mar 2017 15:58:28 GMT):
@andrea.turli it can be any local dir -- the Fabric Node-SDK will use this dir to store its certificates. In the defaultProfile we create it at `~/.composer-credentials/`

andrea.turli (Tue, 14 Mar 2017 16:19:07 GMT):
thanks @dselman, that's useful

When I try to update the business network per instructions at https://fabric-composer.github.io/start/getting-started-cmd-line.html I get an error I did not see a few days ago when I did this. The error is: omposer network update --archiveFile digitalproperty-network@0.0.2.bna --enrollId WebAppAdmin --enrollSecret DJY27pEnl16d Deploying business network from archive digitalproperty-network@0.0.2.bna Business network definition: Identifier: digitalproperty-network@0.0.2 Description: Digital Property Network Error: Failed to load connector module "composer-connector-hlf" for connection profile "defaultProfile" Command failed.

jdockter (Tue, 14 Mar 2017 16:26:48 GMT):
It seems like HLF in general talks about getting participants in a network to sign off or approve assets...ie I have a contract which is an asset and I need three participants int he network to sign off or approve before we can move to the next step in the asset lifecycle...not sure if that is implying some sort of digital signature using a tcert or something different...in Composer would something like approvals be modeled with three different transactions, each limited to a specific participant who would update a specific field in an asset and then once all three fields are updated it's "approved"...or am I missing how that could be modeled?

dselman (Tue, 14 Mar 2017 16:38:25 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=o4sjvxm8EmtXff2Ld) @DennisM330 others have fixed this by doing an `npm uninstall -g composer-cli` followed by `npm install -g composer-cli`

dselman (Tue, 14 Mar 2017 16:39:43 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=8aqqYBTcYPQGCpAXQ) @jdockter I was thinking of adding this to the Perishable-Network sample, so that the Importer, Grower and Shipper each have to sign-off on the Contract before it becomes "approved".

jdockter (Tue, 14 Mar 2017 16:40:10 GMT):
@dselman I was looking at that :)

dselman (Tue, 14 Mar 2017 16:46:20 GMT):
I'm still mulling over the best way of modeling that -- for example, how does someone create a contract and then solicit bids, accept a bid, and then get signatures on the contract? I think we can capture all that using transactions and ACLs...

dselman (Tue, 14 Mar 2017 16:46:49 GMT):
Once the contract is in the SIGNED state then it can no longer be modified...

mikezaccardo (Tue, 14 Mar 2017 16:48:48 GMT):
Thanks for your help @dselman -- I managed to successfully run the "getting started" application against my fabric cluster deployed on an external OpenStack

dselman (Tue, 14 Mar 2017 16:48:50 GMT):
I won't get to that this week however.

dselman (Tue, 14 Mar 2017 16:49:10 GMT):
@mikezaccardo that's awesome. Happy Composing! :-)

jdockter (Tue, 14 Mar 2017 16:51:07 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=7R5XbpiKizR2vAoyD) @dselman sure totally understand...but just conceptually if you did use transactions and ACLs would you then have three fields on the contract for each participant to update to show SIGNED?

dselman (Tue, 14 Mar 2017 16:51:42 GMT):
Yes, I think so. Or we could generalize it into an array of `Signature` concepts.

dselman (Tue, 14 Mar 2017 16:52:06 GMT):
e.g.

dselman (Tue, 14 Mar 2017 16:52:58 GMT):
```concept Signature { --> Business signer o String comments o DateTime dateTime }

In the install page for Fabric Composer, it suggests to download the docker compose.xml file. In the docker compose, it uses hyperledger/fabric-peer:x86_64-0.6.1-preview but in the documentation, it also recommends you to pull fabric base image. What is the purpose of the image.

mikezaccardo (Wed, 15 Mar 2017 03:28:57 GMT):
In the quickstart guide [https://fabric-composer.github.io/start/quickstart.html] is there a way to run part of what `npm install` accomplishes -- namely to generate the `node_modules` folder and `digitalproperty-network` inside it -- without running the Fabric installation all the way (since I'm targeting an external deployment)? I'm currently accomplishing this by running without `sudo` so that the `docker` commands will fail. It's ugly but it works, hoping for something cleaner :-)

mikezaccardo (Wed, 15 Mar 2017 07:39:23 GMT):

Thanks @klorenz

dselman (Wed, 15 Mar 2017 15:37:32 GMT):
@andrea.turli this is incorrect, you can use any Fabric enrollId & secret using the composer-cli :

dselman (Wed, 15 Mar 2017 15:37:36 GMT):
```daniels-mbp:carauction-network dselman$ composer network deploy composer network deploy [options] Options: --help Show help [boolean] -v, --version Show version number [boolean] --archiveFile, -a The business network archive file name [string] [required] --connectionProfileName, -p The connection profile name [string] --enrollId, -i The enrollment ID of the user [string] [required] --enrollSecret, -s The enrollment secret of the user [string] ```

dselman (Wed, 15 Mar 2017 15:38:03 GMT):
Similarly the APIs also allow you to use any enrollId & secret.

andrea.turli (Wed, 15 Mar 2017 15:38:15 GMT):
@dselman you are right, I explained myself very poorly

andrea.turli (Wed, 15 Mar 2017 15:38:55 GMT):
let me rephrase that: what would you recommend ?

andrea.turli (Wed, 15 Mar 2017 15:39:17 GMT):
use an "admin" account to deploy networks, maybe?

andrea.turli (Wed, 15 Mar 2017 15:40:04 GMT):
and then issue Identity to partecipant ?

andrea.turli (Wed, 15 Mar 2017 15:40:34 GMT):
as per https://fabric-composer.github.io/tasks/identity-issue.html ?

dselman (Wed, 15 Mar 2017 15:41:38 GMT):
Yes, you can use an admin account for deployment and then use an application id for the business network connection (to submit transactions). In some cases you'll want individual Fabric enrollment id we be used at the application tier as well -- the challenge of that is you need to manage the certs on behalf of the end user within the application.

dselman (Wed, 15 Mar 2017 15:42:13 GMT):
Various schemes are possible - but the net is that it's not fundamentally different to if you were using the Fabric Node-SDK client.

andrea.turli (Wed, 15 Mar 2017 15:43:45 GMT):
thanks for your quick response, really appreciated

I'll create an issue for that

icordoba (Wed, 15 Mar 2017 17:45:56 GMT):
The cto file with the asset to import needs to be in same directory?

dselman (Wed, 15 Mar 2017 17:46:19 GMT):
No

icordoba (Wed, 15 Mar 2017 17:46:36 GMT):
I mean... in the example cto files are "lib/fileName.cto". They just need to be in same project, correct?

icordoba (Wed, 15 Mar 2017 17:46:54 GMT):
(thanks)

dselman (Wed, 15 Mar 2017 17:47:23 GMT):
Models are by default under the `models` directory. You can organize and name your cto files as you like under that directory.

icordoba (Wed, 15 Mar 2017 17:49:15 GMT):
OK. BTW, Great to consider adding the example. I had tried import as in Java but I was ending the line with ";" so validator was showing an error.

dselman (Wed, 15 Mar 2017 17:49:34 GMT):
Yes -- no `;` in cto

dselman (Wed, 15 Mar 2017 17:50:45 GMT):
Check out some of the sample networks here: https://github.com/fabric-composer/sample-networks/tree/master/packages

dselman (Wed, 15 Mar 2017 17:50:54 GMT):
Though, none use imports AFAIK

icordoba (Wed, 15 Mar 2017 17:51:01 GMT):
Yes :-)

icordoba (Wed, 15 Mar 2017 17:51:16 GMT):
Other question please. When I switch to other file in Playground cto editor I loose all changes. Anyway to store local changes in files?

dselman (Wed, 15 Mar 2017 17:52:47 GMT):
During your editing session you can press the "Update" button to deploy your changes to your local in-browser runtime. To save your work your can "Export" your business network archive. If you unzip the archive you'll find all your source artifacts.

icordoba (Wed, 15 Mar 2017 17:53:52 GMT):
Ah, ok. The editor won't allow deploying if there is any error in the file so it only allows "saving" clean correct cto. Got it..

Cool. I discovered Composer 2 days ago after weeks messing around with Hyperledger and at last I have the feeling to be in the productive path. Very excited. It's a great approach and tool.

dselman (Wed, 15 Mar 2017 17:59:08 GMT):
Thank you -- we are very excited as well. It allows our consultants, partners and customers to quickly model a business network and generate APIs and UIs in a few hours. What used to take weeks...

Hi Composer team....I saw *prereqs-ubuntu16.sh* in your getting-started/scripts directory, so I ran it on a fresh xenial system I spun up in vagrant. It ran great, but when I did my first npm global install of composer-cli it burped because python was missing. I realize any self-respecting programmer should have python on their system and it was easy as pie to fix, but just thought I'd point it out as evidently the vagrant box for ubuntu xenial (I did *vagrant init ubuntu/xenial64* to get going) does not already have python, so I thought maybe you'd want to toss an apt install of that into your prereq script. Actualy I don't know if this is a function of vagrant's xenial64 box vs. its trusty64 box, or if it's a composer v0.4x vs v0.5 thing- I didn't run into this problem on ubuntu/trusty64, but on the other hand, this is the first time I've run through this since you bumped up composer to v0.5.

davidkel (Wed, 15 Mar 2017 19:30:22 GMT):
@silliman python 2.7 is required for node-gyp and so will have always required python because of it. Although I don't have a desktop xenial install to hand I bet that comes with python already installed and ready to use. It definitely isn't included in the xenial vagrant box. Maybe it was done that way to allow developers to choose which version of python they want ?

@davidkel Hi David, I agree, I was surprised to discover that the xenial box provided by hashicorp didn't have Python on it, but it didn't. Just thought I'd point it out.

davidkel (Wed, 15 Mar 2017 19:39:09 GMT):
@silliman I was surprised too as I use vagrant for my development env, thanks for reminding me though probably worth an creating an issue to cover a vagrant environment

silliman (Wed, 15 Mar 2017 19:40:16 GMT):
@davidkel if you like I can create the issue....I'm just creating a fresh ubuntu/trusty64 environment with vagrant to see if this consideratoin applies there as well

davidkel (Wed, 15 Mar 2017 19:40:46 GMT):
that would be great if you could, many thanks @silliman

silliman (Wed, 15 Mar 2017 19:43:35 GMT):
@davidkel will do as soon as I determine if this applies to their xenial64 box only or to trusty64 as well... of course I downloaded a fresh xenial box in 2 minutes and now the progress bar is telling me it will be 2 hours until trusty64 is downloaded, but that is just par for the course! :-)

davidkel (Wed, 15 Mar 2017 19:45:43 GMT):
I'm almost certain trusty64 box has python installed

silliman (Wed, 15 Mar 2017 19:48:41 GMT):
@davidkel me too as I didn't explicitly install it and it's there... I'll just write up an issue now and if it does turn out that trusty64 is in play for this I can always update it later

davidkel (Wed, 15 Mar 2017 19:50:11 GMT):
cool, thanks:thumbsup:

@davidkel yw ... Issue 478 https://github.com/fabric-composer/fabric-composer/issues/478

silliman (Wed, 15 Mar 2017 20:46:53 GMT):
@davidkel just FYI as is it irrelevant in that a quick google search indicates node-gyp needs python 2.7 and doesn't play nice with python 3, but the ubuntu/xenial64 vagrant box does have python 3 out of the gates, just not python 2.7

davidkel (Wed, 15 Mar 2017 21:45:46 GMT):
@silliman Ah yes, I remember now. node-gyp launches python but although python3 is present it isn't symlinked to the python name, so is only launched by doing python3. When I installed python 2.7 into xenial I had to symlink it to the python name. Did you need to do that as well ?

silliman (Wed, 15 Mar 2017 22:38:29 GMT):
@davidkel no I didn't need to do that.. an install of *python-minimal* did the trick with no further action necessary. The ubuntu/xenial64 vagrant box had not linked python3 to python, which I guess would've caused this extra step of linking python27 to python

Hi, is there any documentation about the language spec of fabric-composer? I'd like to know a full spec of how the models, transactions and access control can be defined and what is the expected behavior.

sstone1 (Thu, 16 Mar 2017 08:21:04 GMT):
@sachikoy there's some information in the documentation: https://fabric-composer.github.io/reference/cto_language.html (Modelling language) https://fabric-composer.github.io/reference/acl_language.html (ACL language) https://fabric-composer.github.io/reference/js_scripts.html (TP functions) https://fabric-composer.github.io/jsdoc/module-composer-runtime.html (TP function API)

We also have the grammar checked into Git, we use PEG.js to generate parsers: https://github.com/fabric-composer/fabric-composer/blob/master/packages/composer-common/lib/introspect/parser.pegjs (Modelling language) https://github.com/fabric-composer/fabric-composer/blob/master/packages/composer-common/lib/acl/parser.pegjs (ACL language)

paul.sitoh (Thu, 16 Mar 2017 10:37:50 GMT):
Does anyone know if composer "javascript" style transaction definition support promises and lambda? Otherwise we could get code that looks like a cone of callbacks making the definition unreadable.

Jakeeyturner (Thu, 16 Mar 2017 10:45:31 GMT):
Hi @paul.sitoh, yes the JS Transaction functions handle promises - https://github.com/fabric-composer/sample-networks/blob/master/packages/carauction-network/lib/logic.js#L56

Jakeeyturner (Thu, 16 Mar 2017 10:50:12 GMT):
and yes, I believe they handle lambda as well

sstone1 (Thu, 16 Mar 2017 11:25:00 GMT):
Arrow functions are not supported.

paul.sitoh (Thu, 16 Mar 2017 11:32:35 GMT):
@Jakeeyturner How do you import an external javacript module to the transaction defintion?

paul.sitoh (Thu, 16 Mar 2017 11:33:22 GMT):
Such as momentum, etc?

paul.sitoh (Thu, 16 Mar 2017 11:33:47 GMT):
sorry moment.js

Jakeeyturner (Thu, 16 Mar 2017 11:34:30 GMT):
We currently don't support 'require' or the importing of any non-native JS libraries. Correct me if I'm wrong @sstone1

paul.sitoh (Thu, 16 Mar 2017 11:34:50 GMT):
Bummer :-(

sstone1 (Thu, 16 Mar 2017 11:42:02 GMT):
Correct. You could try using browserify/webpack to inline everything into a single JS file that is part of the business network, but I don't think anybody has tried that yet.

sstone1 (Thu, 16 Mar 2017 11:43:20 GMT):
@paul.sitoh what do you want to use the libraries for?

sstone1 (Thu, 16 Mar 2017 11:44:01 GMT):
We've had lots of people say "how can I import modules" without saying what they want to use them for, so it would be good to get some concrete examples.

Jakeeyturner (Thu, 16 Mar 2017 11:46:39 GMT):
https://jira.hyperledger.org/browse/FAB-2331?jql=text%20~%20%22nodejs%20chaincode%22 - This would definitely help Fabric Composer

paul.sitoh (Thu, 16 Mar 2017 11:49:32 GMT):
(1) To divide my code into reusable components just like you would divide your code into multiple files

paul.sitoh (Thu, 16 Mar 2017 11:49:55 GMT):
(2) Reuse some external maths algorithm

paul.sitoh (Thu, 16 Mar 2017 11:49:55 GMT):
(2) Reuse some external maths algorithm via npm style

paul.sitoh (Thu, 16 Mar 2017 11:52:05 GMT):
For example, say in finance. The chaincode needs to work present value of the value of a house. The last thing I want to do is to write

paul.sitoh (Thu, 16 Mar 2017 11:52:05 GMT):
For example, say in finance. The chaincode needs to work present value of the value of a house. The last thing I want to do is to write the math over and over again for different projects

sstone1 (Thu, 16 Mar 2017 11:52:16 GMT):
So (1) is possible - all functions should be in scope for you to call, we refer to these as utility functions.

paul.sitoh (Thu, 16 Mar 2017 11:52:23 GMT):
some crazy math like present value

paul.sitoh (Thu, 16 Mar 2017 12:11:33 GMT):
Any if it is not possible, I guess we have to keep the transaction definition as simple as possible and let the app level do the heavy lifting. So it is not a deal breaker

paul.sitoh (Thu, 16 Mar 2017 12:13:47 GMT):
Just out of curiosity, I can understand the concept of a chaincode as a computer representation of some legal contracts in the real work to govern transactions of assets. But what does composer's "transaction" mean in this context?

sstone1 (Thu, 16 Mar 2017 12:15:18 GMT):
https://fabric-composer.github.io/concepts/businessnetwork.html

paul.sitoh (Thu, 16 Mar 2017 12:16:47 GMT):
Yes I read it on the doc and this is what it says:

paul.sitoh (Thu, 16 Mar 2017 12:17:00 GMT):
"Transactions. These are operations that are performed on assets and other resources as they move through their lifecycle within the business network"

paul.sitoh (Thu, 16 Mar 2017 12:20:50 GMT):
It kind of give me the impression that it is doing two things here. One, executing a real world transaction. For example, someone buy a house, and ownership is transfer -- i.e. the transaction. In my mind this is usually done at the app level. The other, is enforcement of transaction, i.e. is the transfer of ownership permitted. I normally associate this with the role of a chaincode.

paul.sitoh (Thu, 16 Mar 2017 12:20:50 GMT):

paul.sitoh (Thu, 16 Mar 2017 12:21:36 GMT):
Question: in composer when we define a transaction, are are doing two things as describe above, in one code execution?

paul.sitoh (Thu, 16 Mar 2017 12:39:18 GMT):
In other words. Should we be coding contractual logic and transactional logic in the transaction definition?

paul.sitoh (Thu, 16 Mar 2017 12:39:18 GMT):
In other words. Should we be coding contractual logic and transactional logic in the transaction definition? From a good coding practice perspective.

sstone1 (Thu, 16 Mar 2017 12:53:24 GMT):
The real world transaction is modelled as a Composer transaction. The transaction processor both enforces the transaction - is it permitted, does the submitter own the house, etc. - but also records the transaction and transfer of ownership (by transferring assets).

paul.sitoh (Thu, 16 Mar 2017 12:59:08 GMT):
Is there a way to unit test the logic separately -- i.e. contractual and transactional? Here at the Garage we practice TDD, where we write test then implementation. So not being able to separate out modules kind of make it somewhat difficult, but not impossible, to practice TDD.

paul.sitoh (Thu, 16 Mar 2017 12:59:51 GMT):
We might also need to be able to smoke testing -- i.e. test where a fabric network is alive or not before deployment.

dselman (Thu, 16 Mar 2017 13:01:49 GMT):
Yes, you can write Mocha/Chai unit tests. Here is an example: https://github.com/fabric-composer/sample-networks/blob/master/packages/perishable-network/test/perishable.js

dselman (Thu, 16 Mar 2017 13:02:05 GMT):
It's a great way to make sure your logic is functional before you deploy to a Fabric.

dselman (Thu, 16 Mar 2017 13:03:36 GMT):
To smoke test you can write unit tests that run against a real network (system tests), or you can use the `composer transaction submit` cli command to submit ad-hoc transactions, or use the REST API generated by `composer-rest-server`

dselman (Thu, 16 Mar 2017 13:03:49 GMT):
An article on testing business networks would be very useful...

dselman (Thu, 16 Mar 2017 13:04:42 GMT):
`composer network ping` will tell you whether a business network is deployed and the version.

paul.sitoh (Thu, 16 Mar 2017 13:29:11 GMT):
When you say "an article on testing business networks would be very useful ..." do you mean none exists yet?

paul.sitoh (Thu, 16 Mar 2017 13:29:11 GMT):
@dselman When you say "an article on testing business networks would be very useful ..." do you mean none exists yet?

dselman (Thu, 16 Mar 2017 13:51:17 GMT):
correct

dselman (Thu, 16 Mar 2017 13:51:47 GMT):
We don't have anything that pulls all this together into one place.

dselman (Thu, 16 Mar 2017 13:52:10 GMT):
We also have a strong CI story -- we unit and system test using Travis Ci.

paul.sitoh (Thu, 16 Mar 2017 14:09:28 GMT):
Ok

paul.sitoh (Thu, 16 Mar 2017 14:09:50 GMT):
When we work through an example we'll document it

jdockter (Thu, 16 Mar 2017 14:26:51 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=xYXQa3TC8raxnrGmi) @dselman would love to hear/see a detailed story on that setup and configuration or thoughts around alternative CI options other than Travis...ie Jenkins, Bluemix Continuous Delivery, Jazz Build Engine, etc..

pascallouis (Thu, 16 Mar 2017 14:50:25 GMT):
@sstone1 and @dselman I'm struggling to move to 0.5.1 toolkit, with a similar error than someone reported "Deployed chain-code (0.4.3) is incompatible with client (0.5.1)"

pascallouis (Thu, 16 Mar 2017 14:51:05 GMT):
I'm using only local installs, and packaging my bnd with `node node_modules/composer-cli/cli.js archive create ...`

pascallouis (Thu, 16 Mar 2017 14:51:23 GMT):
I can confirm this is all at 0.5.1

pascallouis (Thu, 16 Mar 2017 14:51:45 GMT):
and same for the server `node node_modules/composer-rest-server/server/server.js -p defaultProfile -n namehere -i WebAppAdmin -s DJY27pEnl16d`

pascallouis (Thu, 16 Mar 2017 14:52:46 GMT):
where would 0.4.3 version appear? uninstall all global references to composer, literally `npm -g ls | grep composer` shows nothing relevant

Jakeeyturner (Thu, 16 Mar 2017 14:54:10 GMT):
It sounds like that when you deployed a business network at the time you used Composer-CLI@0.4.3

Jakeeyturner (Thu, 16 Mar 2017 14:54:36 GMT):
So you need to do something like `node node_modules/composer-cli/cli.js network deploy ... `

Jakeeyturner (Thu, 16 Mar 2017 14:54:49 GMT):
(as you now have 0.5.1)

pascallouis (Thu, 16 Mar 2017 14:54:52 GMT):
Yes, but I did `node node_modules/composer-cli/cli.js network update -a mynetwork@0.0.1.bna -i WebAppAdmin -s DJY27pEnl16d`

pascallouis (Thu, 16 Mar 2017 14:56:26 GMT):
How can I wipe out, and restart? Would rather start clear.

pascallouis (Thu, 16 Mar 2017 14:56:26 GMT):
How can I wipe out, and restart? Would rather start clean.

Jakeeyturner (Thu, 16 Mar 2017 14:57:49 GMT):
To clear everything out and start again, you'd need to bring down your Fabric, clear up your connection profile in the .composer-connection-profiles, clear out your .composer-credentials directory, bring up a new Fabric, deploy your business network archive file

Jakeeyturner (Thu, 16 Mar 2017 14:58:04 GMT):
This should work as it appears you've got the latest CLI version

BrijeshJ (Thu, 16 Mar 2017 14:59:42 GMT):
Hi, morning guys, trying to login to the online meeting, would the login id be same the my email registered here on slack/

pascallouis (Thu, 16 Mar 2017 15:00:25 GMT):
to be clear on clear up, essentially `rm -Rf ~/.composer-connection-profiles/ ~/.composer-credentials/`

pascallouis (Thu, 16 Mar 2017 15:00:46 GMT):
stop all docker containers, restart fabric, and then try again?

Jakeeyturner (Thu, 16 Mar 2017 15:00:58 GMT):
yep

pascallouis (Thu, 16 Mar 2017 15:01:15 GMT):
locally, where does the persistence of the network's data live?

Jakeeyturner (Thu, 16 Mar 2017 15:06:58 GMT):
in the ledgers worldstate (on the peer)

jworthington (Thu, 16 Mar 2017 15:07:35 GMT):

jworthington (Thu, 16 Mar 2017 15:11:40 GMT):
Ah, musta been changed since I copied and pasted into my calendar. no bother

pascallouis (Thu, 16 Mar 2017 15:12:04 GMT):
@Jakeeyturner sorry for clearly noob question, but the docker instance running the peer must store it's data somewhere on disk (I'm on Mac OS). Where is that data? I'd like to wipe it out too.

davidkel (Thu, 16 Mar 2017 15:20:13 GMT):
@pascallouis you could stop the docker container and start a new one

Jakeeyturner (Thu, 16 Mar 2017 15:20:51 GMT):
@pascallouis They'll be able to help you with that over at #fabric as I'm not 100% sure

Jakeeyturner (Thu, 16 Mar 2017 15:20:51 GMT):
@pascallouis They'll be able to help you with that over at #fabric-questions as I'm not 100% sure

pascallouis (Thu, 16 Mar 2017 15:21:33 GMT):
ok, will do

pascallouis (Thu, 16 Mar 2017 15:21:43 GMT):
wiping everything as you suggested @Jakeeyturner helped

pascallouis (Thu, 16 Mar 2017 15:22:15 GMT):
the only thing is that I copy pasted the `.composer-credentials/member.WebAppAdmin` from a previous install as I did not know how to recreate it

Jakeeyturner (Thu, 16 Mar 2017 15:23:24 GMT):
That is a credential that Fabric creates when chaincode is deployed (e.g. when a business network is deployed in our case)

Jakeeyturner (Thu, 16 Mar 2017 15:24:09 GMT):
So, copying that file isn't a good idea as it's generated using some crypto stuff

pascallouis (Thu, 16 Mar 2017 15:26:06 GMT):
ah, ok

pascallouis (Thu, 16 Mar 2017 15:27:02 GMT):
In version 0.5, no more ability to list transactions? Seems only posting transactions is exposed via the Swagger UI of the explorer.

pascallouis (Thu, 16 Mar 2017 15:46:13 GMT):
@Jakeeyturner Any option to list all operations that occurred? Ideally, with block number they made it in!

paul.sitoh (Thu, 16 Mar 2017 15:46:47 GMT):
One more question. I notice that there is no Business Network Initialisation function -- i.e. equivalent of composer Transaction -- but something to initialise the state of Assets when you first activate the network. Is there one?

Jakeeyturner (Thu, 16 Mar 2017 15:50:37 GMT):
@pascallouis Nope. Something like the Blockchain Explorer might help. It'll show you the blocks, and you should be able to decode the transactions - https://github.com/hyperledger/blockchain-explorer

pascallouis (Thu, 16 Mar 2017 15:52:21 GMT):
interesting, will check it out

Jakeeyturner (Thu, 16 Mar 2017 15:52:36 GMT):
@paul.sitoh We have an issue raised for a 'setup' here - https://github.com/fabric-composer/fabric-composer/issues/46. Although something similar can be created as shown in our sample network here - https://github.com/fabric-composer/sample-networks/blob/master/packages/perishable-network/lib/logic.js#L127

Jakeeyturner (Thu, 16 Mar 2017 15:53:39 GMT):
So sending a `org.acme.shipping.perishable.SetupDemo` transaction will execute that JS logic and will create some sample participants, assets, etc

New UI looks nice... Any thoughts on generating / displaying forms based on the json instead of direct editing? (with the option to view / direct edit as well) ?

Jakeeyturner (Thu, 16 Mar 2017 16:40:30 GMT):
@atomkinson Addressed in here :) - https://github.com/fabric-composer/fabric-composer/issues/219

@Jakeeyturner Thanks sir! :-)

Jakeeyturner (Thu, 16 Mar 2017 16:43:08 GMT):
No worries!

EdMoffatt (Thu, 16 Mar 2017 16:45:43 GMT):
As mentioned on the community call, @atomkinson - here are some low-fis of what we were thinking around these forms: https://xd.adobe.com/view/fac72420-bc95-4699-b30b-2d352e7ec6cb/ So we're planning to have form *and* JSON views that update each other. In cases where the object is too complex to generate a form, we fall back on JSON only. If an object references instances of a Composer object, we're planning to offer dropdowns to pick from (to remove the need to remember assetIDs etc.!)

VipinB (Thu, 16 Mar 2017 16:45:47 GMT):
Great first demo thanks everyone

sstone1 (Thu, 16 Mar 2017 16:49:16 GMT):
Thank you all for attending!

atomkinson (Thu, 16 Mar 2017 16:51:16 GMT):
Agree with @VipinB - really appreciate the work here. I think the idea fills what I think is a gap that is typical in the blockchain space. Everyone seems to be focused directly on the blockchain tech itself, and uses for it, but there is a big lack of tools and layers of abstraction that will be needed to bring the tech to the masses. Really exciting project imho.

sstone1 (Thu, 16 Mar 2017 16:54:49 GMT):

VipinB (Thu, 16 Mar 2017 17:01:48 GMT):
Maybe due to some setting like block popups or maybe due to some ports being blocked from inside firewall. It might help to get more transparency into errors if possible.

sstone1 (Thu, 16 Mar 2017 18:03:52 GMT):
I know we don't have many IE users in the team; we need to do some work to improve our IE/Edge support and also Windows support for the Composer tooling.

@sstone1 not a supporter of IE, but this is what we have in the Enterprise

any updates on the CouchDB integration in fabric-composer ?

sstone1 (Fri, 17 Mar 2017 11:00:29 GMT):
@MartinMateev we're still working on v1.0 support. Once that goes in, it will work fine with either CouchDB or LevelDB. I suspect you're after complex query support (built on top of CouchDB queries), which we haven't started working on yet.

paul.sitoh (Fri, 17 Mar 2017 11:49:02 GMT):
Folks, I am a bit confuse about the "participant" aspects of the composer. Does it refer to a participant role or participant individual?

paul.sitoh (Fri, 17 Mar 2017 11:49:30 GMT):
There seemed to be a problem with the way cert is issued

paul.sitoh (Fri, 17 Mar 2017 11:49:30 GMT):
There seemed to be a problem with the way cert is issued -- i.e. it seemed to be issued to an individual. As an analogy, the implementation is akin to relying on MySQL to assign credentials for individual users as opposed to assigning it to a role (i.e. web user).

annbnn (Fri, 17 Mar 2017 11:49:35 GMT):
@sstone1 Is there any composer ui tutorial or movie ?

dselman (Fri, 17 Mar 2017 12:01:24 GMT):
@paul.sitoh you are free to model participants (types) -- so they can represent individuals, roles, organizations or whatever is appropriate for the problem you are trying to solve. For example, participants can have relationships to other participants, allowing you to create a manager that is related to a set of employees etc. An identity is issued to a participant instance. I might model a Bank as a participant type, and "ABC Bank" would be an instance of Bank. I could then issue an identity (cert) for ABC Bank. When it comes to writing ACLs your rules can rely on types of participant, instances, or even properties on instances. So I could have a rule that says "any instance of Bank can access this asset", or "ABC Bank can access this asset", or even "Any employee of ABC Bank can access this asset".

dselman (Fri, 17 Mar 2017 12:02:10 GMT):
The model is flexible enough to support static roles as well as dynamic roles.

@annbnn the website has been updated with new material for example https://fabric-composer.github.io/tutorials/defining-a-business-network.html might be of interest as that uses the composer-playground (the new version). Also now we have updated docs I'll certainly want to record the getting started video

paul.sitoh (Fri, 17 Mar 2017 12:39:06 GMT):
@dselman Ok. The only concern I have is that it is going to make writing ACL complicated. I would have preferred to delegate participant instance identity (particularly real person -- i.e. Paul Sitoh) to be managed by LDAP and leave keep blockchain identity services to be role based. No matter, we are where we are -- so to speak.

paul.sitoh (Fri, 17 Mar 2017 12:41:38 GMT):
On another note: I was wondering if it is possible to specify the location of compose "caching/config" folders namely .compose-* to be at another location other than home directory? Example, you can specify export COMPOSE_HOME=${PWD}? I understand the identity wallet is held there and if we wanted to do DevOps now we'll need to be able to make it available to CI so it can perform deployment.

dselman (Fri, 17 Mar 2017 13:22:13 GMT):
@paul.sitoh if you could write up a user story for a business network using LDAP and how you'd expect it to work with certs etc that would be great. I'm sure we've got lots to learn about auth/identity in general and will evolve.

dselman (Fri, 17 Mar 2017 13:23:59 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=o8GRfkajf4xFZREBo) @paul.sitoh the connection profiles are loaded from user home dir -- the location of the certs is in the connection profile. In our tests we use an in-memory file system for the user home dir.

jdockter (Fri, 17 Mar 2017 13:40:33 GMT):
@paul.sitoh @dselman I believe Fabric has support to plug in LDAP, https://jira.hyperledger.org/browse/FAB-1144 ...this seems like more of what existing enterprises are going to want to do rather than keeping another set of identities

GeorgSchultz (Fri, 17 Mar 2017 13:40:44 GMT):
Is there a roadmap for the Fabric-Composer development?

paul.sitoh (Fri, 17 Mar 2017 13:43:39 GMT):
@dselman FYI To get round this problem, and making it compatible with Bluemix, kind of convert the profile to make it an environmental variable instead. So in my case, I created and environmental variable call export COMPOSER_CONNECT_PROFILE={"type": "hlf", "membershipServicesURL": "grpc://localhost:7054", "peerURL": "grpc://localhost:7051", "eventHubURL": "grpc://localhost:7053", "keyValStore": "/Users/blockchain/.composer-credentials", "deployWaitTime": "300", "invokeWaitTime": "100", "networks": { "marbles": "e8bacaf4c097273251293e62a9b68445c1a69a4e633bbbdeddab0e1bbc296379"}. In my apps i then use process.env.COMPOSER_CONNECT_PROFILE rather than rely on the .composer config folder

Not an idea solution. Ideally the KeyStoreVal should be in the cloud such as objectstore so it can be easily shared.

@sstone1 @dselman Will be interesting to put the Identity parts of this in the Identity WG paper so that it can be a launching pad for the Identity interface definition see identity-wg for more details

VipinB (Fri, 17 Mar 2017 14:02:22 GMT):
If you have any diagrams for this or can point to them, I can get them into the doc

paul.sitoh (Fri, 17 Mar 2017 14:24:08 GMT):
@jdockter thanks for info. I expect the composer team will be looking at it. I appreciate their pain in providing a solution in the short term. Identity/credential management is a complex issue

@VipinB definitely, I am still planning on writing up that document for the Identity WG

The team has released v0.5.5. Lots of work has gone in, particularly around the docs, fixing defects, website and the Playground. I will also be demoing Fabric Composer running on HLF v1 at the IBM InterConnect conference next week.

dselman (Fri, 17 Mar 2017 18:57:17 GMT):
A big THANK YOU to everyone that has contributed and tested. I am certainly biased, but I believe that together we're making Fabric Composer the best blockchain development platform in the industry! :-)

Hello, I have tried running Playground locally both as a Docker instance and installing it via npm, but in both I get same message: "Connection Profiles are not available in Web Playground. If you like what you see, you can install a a local version of Fabric Composer". Does it mean that Playground can not be used to deploy into real Fabric and that I must use CLI for that or there is a way to configure Playground to use a Connection Profile?

icordoba (Sun, 19 Mar 2017 18:22:35 GMT):
I ask this because in docs I see "The Fabric Composer Playground is a web development experience that allows you to develop a business network definition, deploy that business network definition to a running instance of Hyperledger Fabric, ...". Thanks for any directions.

dselman (Sun, 19 Mar 2017 18:30:10 GMT):
@icordoba the new Playground doesn't yet support web profiles -- we'll be working on that next week (it's purely a UI limitation at this point). You can use the older Composer UI against a HLF.

I'll give older version a try but no problem. I think I can wait :-) I just wanted to make sure I wasn't missing something on 0.5.5. I think I'll use Playground to work and test, export and deploy locally with CLI once tested. Thanks.

dselman (Sun, 19 Mar 2017 18:33:25 GMT):
We will support both composer-playground and composer-ui until we get to feature parity, then we will retire composer-ui

Hello again... now a question about transactions: I am trying to submit a transaction using "composer transaction submit...". The command is accepted only if I add a random transactionId, but in Playground the JSON to submit a transaction does not include the transaction id and is executed. How should I generate the transaction Id if the transaction has not been executed yet? Thanks.

Hi -- Using the excellent Fabric Composer docs, I have successfully built a Business Network. I was able to test it in `composer-playground`. Then, I deployed the Business Network to a local instance of HyperLedger Fabric. I was able to use `composer-rest-server` and test the endpoints individually. So far, so good! However, I need some pointers to build an App(Web, mobile, or dekstop) that would use/exercise those endpoints in response to UI gestures. Ideally, the instructions should be for manually handcrafting an App instead of automatically generating and App as one gets lost in all the artifacts that get created behind the scenes to satisfy the requirements of the app framework.

@shanlusun hyperledger fabric have an example of setting up v1.0 in their code code base in the examples/e2e_cli directory. Also the node sdk in their e2e test directory sets up a v1.0 environment. Note that as of 0.5.5 fabric composer has some support for v1.0 but it isn't complete yet and there isn't any docs about it at the moment.

shanlusun (Mon, 20 Mar 2017 08:57:20 GMT):
@davidkel Yes, there is an example *hackfest/docker-compose-gettingstarted.yml for Fabric v1.0* which helped me to setup a development network in the same server quickly. With this environment the example code runs well(hackfest/src/github.com/example_cc/example_cc.go).```

shanlusun (Mon, 20 Mar 2017 08:59:00 GMT):
But now I want to setup a real network for production with several servers. Also I am not sure how to make a new peer join an existing blockchain network.

@icordoba what error do you get if you don't add the transactionId to your json when you submit via the command line ? Both the playground and the cli should be using the same logic here such that if you don't supply a transaction id then it provides a random uuid for the transactionId for you.

GeorgSchultz (Mon, 20 Mar 2017 10:42:46 GMT):
Is there a roadmap for the Fabric-Composer development?

uber.twin (Mon, 20 Mar 2017 10:47:19 GMT):
Hi, I am trying to add a participant twice(duplicate ID) but instead of an error, I get a transaction timeout error. Is this a problem with my client application or this is the manner that the runtime handles such cases?

shanlusun (Mon, 20 Mar 2017 10:47:43 GMT):
@davidkel thanks so much! Will double check the latest version for my problem.

Jakeeyturner (Mon, 20 Mar 2017 10:48:52 GMT):
@uber.twin This is how the runtime handles it at the moment, if you were to check the chaincode docker container, it'd mention that the participant already exists

uber.twin (Mon, 20 Mar 2017 10:53:02 GMT):
alright, thank you

jdockter (Mon, 20 Mar 2017 10:53:32 GMT):
@Jakeeyturner what is the best practice today for debugging transactions?

Jakeeyturner (Mon, 20 Mar 2017 11:09:21 GMT):
It's worth writing unit tests, but if you're using the CLI to submit transactions you should be getting some trace files in a `logs` directory

uber.twin (Mon, 20 Mar 2017 15:30:04 GMT):
they are in different namespaces, yes

uber.twin (Mon, 20 Mar 2017 15:30:29 GMT):
participant and the asset have dedicated namespaces

dselman (Mon, 20 Mar 2017 15:30:38 GMT):
As a workaround can you put them in the same ns until we fix https://github.com/fabric-composer/fabric-composer/issues/469 ?

uber.twin (Mon, 20 Mar 2017 15:30:54 GMT):
sure, thank you

dselman (Mon, 20 Mar 2017 15:31:04 GMT):

uber.twin (Mon, 20 Mar 2017 16:04:38 GMT):
I changed all definitions to use the same namespace looks like I can have different files to define the assets and the participants but the transactions and participants need to share the same file

dselman (Mon, 20 Mar 2017 16:20:13 GMT):
1 ns per file. 1 file per ns.

uber.twin (Mon, 20 Mar 2017 16:22:51 GMT):
yes, I just realized that. it did deploy with 2 files and same namespace for participants and assets but it wasn't working

Hello -- I have implemented a simple Business Network(.cto and .js) for **Hyperledger Fabric 0.6** using **Fabric Composer 0.5**. However, I did not have to write any chaincode -- `Init()`, ``Invoke()`, and `Query()` -- functions. Is that abstracted away too? Or, is the chaincode needed only for non-trivial scenarios?

@bloxhead some quick questions to see if we can try to find out the problem 1. can you run `composer -v` and post the results 2. what version of ubuntu are you running ? 3. were there any obvious errors when you installed composer-cli ? nvm shouldn't have an impact on this as I use it myself. This error is usually because it cannot load composer-connector-hlf npm module, so it might be worth doing a `npm list -hg --depth=5` and posting the composer-cli tree part of the out as well.

Hello, have an old BNA for the car auction sample that used to work well and it is still doing so with an old composer-cli. However, with the latest level of code, I get: ``` composer-cli network deploy -a ./BNA/carauction-network.bna -i admin -s Xurw3yU9zI0l Deploying business network from archive ./BNA/carauction-network.bna ParseException: Expected "rule", comment, end of line or whitespace but "A" found. Line 4 column 1 Command failed. ``` Has anything changed in the parser or syntax of BNs? If so, where can I find an updated car auction sample application?

jdockter (Tue, 21 Mar 2017 12:23:50 GMT):
@elisabetta I ran into the same thing...there is a new rules format so make sure your permissions.acl looks like what is documented here, https://fabric-composer.github.io/reference/acl_language.html

davidkel (Tue, 21 Mar 2017 12:27:04 GMT):
@bloxhead so the list for cli looks ok and I gather you have the cli working now, but the rest server is failing. Could you paste the composer-rest-server npm list tree up to see if it is missing any modules ?

elisabetta (Tue, 21 Mar 2017 12:30:24 GMT):
@jdockter: thanks. It helps. I'll see if I can find the latest version somewhere. (I can't modify it, as importing it into the playground doesn't work for the same reasons as the deployment failure).

davidkel (Tue, 21 Mar 2017 12:45:54 GMT):
@elisabetta you can get the latest car auction network as follows - mkdir temp - cd temp - npm install carauction-network - composer archive create -a carauction.bna -t module -n carauction-network

jdockter (Tue, 21 Mar 2017 13:00:07 GMT):
Is it possible to have multiple values for a single rule, for example I want three different participants to be able to create an order.....or I want one participant to have update and delete authority for an asset...if so what is the syntax, just a comma to be the deliminator?

Parsing problem solved! I now get the same problem as @bloxhead

mbwhite (Tue, 21 Mar 2017 13:51:44 GMT):
I ran into the similar problems as @bloxhead with the ``` Failed to load connector module "composer-connector-hlf" for connection profile "car" ``` As it was reproducible locally I've started to look into what the issue could be.... I can't definately say - but at present the problem is looking to be towards a problem with the Node GPRC module installation. When the `composer-cli` is installed the node-gyp build runs. I believe that this needs Python 2 to be installed. Could you see if python is installed please?

mbwhite (Tue, 21 Mar 2017 13:52:12 GMT):
`sudo apt-get install python` is what I've used to add python

elisabetta (Tue, 21 Mar 2017 13:53:41 GMT):
yes python is installed: ``` root@ubuntu1604:~/BC-Connect/CICS-CarAuction/config# python -V Python 2.7.12 ```

elisabetta (Tue, 21 Mar 2017 13:53:41 GMT):
yes python is installed: ``` root@ubuntu1604:~/config# python -V Python 2.7.12 ```

elisabetta (Tue, 21 Mar 2017 13:56:00 GMT):
other than python, node-gyp build required g++ and make

As I had python missing it seemed like that could be the issue.

(note I had to add diagnostic info to get that error)

mbwhite (Tue, 21 Mar 2017 14:22:16 GMT):
So I've managed to get past the error above with both installing python and increasing the memory I had on my vm to 6gb... this has worked correctly.

elisabetta (Tue, 21 Mar 2017 15:11:25 GMT):
I don't think it is a problem with memory in my case. My VMs have quite some memory. node-gyp build completes without errors.

elisabetta (Tue, 21 Mar 2017 15:12:12 GMT):
What do I have to do to get more diagnostics? I don't get any error message in the log file. Only the stdout.

davidkel (Tue, 21 Mar 2017 15:19:07 GMT):
@elisabetta I assume this is with the cli, could you also do a npm list -g --depth=5 and report on composer-cli ? The error results from issuing a node require for the particular npm module and node returning not found

@elisabetta so there isn't anything obvious if something is missing causing the module not to load. I assume you are using node 6, not node 7 ?

elisabetta (Tue, 21 Mar 2017 16:05:03 GMT):
node v6.10

davidkel (Tue, 21 Mar 2017 16:09:50 GMT):
@elisabetta you can get more debug info node module loading by setting the environment variable ``` export NODE_DEBUG=module ``` and rerunning the command. It will generate a lot of output though

It also seems like I can't just give update authority to a property of a resource but would also have to give update authority to the resource itself before I limit the authority to the property...but again maybe I have something wrong...please advise.

Why can I not submit a transaction ?

jdockter (Tue, 21 Mar 2017 17:16:21 GMT):
It looks like you have modeled your asset with an identifier of assetId...you gave assetId a value of 1, so that transaction needs to reference the value of asset as 1, not assetId:1

@icordoba great questions, hopefully we've manage to answer them for you now

@elisabetta I haven't been able to recreate the problem so would be great if you can see if you can get some info with the debug mode for node.

davidkel (Tue, 21 Mar 2017 20:08:44 GMT):
@bloxhead are you still having problems with the rest server ? if so then we could use more debug info using the ``` export NODE_DEBUG=module ``` option before running the rest server and hopefully it will output some info as to what the problem is

annbnn (Tue, 21 Mar 2017 20:54:43 GMT):
Yes thank you @jdockter

bravera (Wed, 22 Mar 2017 10:59:58 GMT):
I have been thinking about Participants in a business network. Participants should have a known identity, which I am assuming means that they need to registered with Member services? Does this also mean that a participant would have a peer running in the network? In the Property Network example, a property owner will want to be involved in a transaction to sell the property, that only the buyer and perhaps the conveyancer is involved in (blockchain could be used to reduce the role (possibly eliminate) the role of the agent in the property market)........I am guessing this means that buyers and sellers will all need to be running a peer in the network for this to happen using channels? Am I missing something?

elisabetta (Wed, 22 Mar 2017 11:07:32 GMT):
@davidkel: I've managed to get past that problem. There were some node-gyp modules missing, despite the fact that the build seemed to complete successfully. I ran an upgrade and that solved that issue. I can replicate the problem if you need to track down what the problem was, as I have a clone of the VM before my attempts to install composer.

davidkel (Wed, 22 Mar 2017 11:28:49 GMT):
@elisabetta glad you got passed the problem, I would be very interested to recreate the problem as it would be a good test to see if we can improve the error message to indicate what the problem was

davidkel (Wed, 22 Mar 2017 11:31:36 GMT):
@bravera Participants who want to transact on the fabric will need to be issued with identities.

bravera (Wed, 22 Mar 2017 11:38:39 GMT):
@davidkel right but how does the privacy piece work regarding transactions involving these participants? Do they need a channel to transact upon, and if so, does that mean they have to be running a peer?

elisabetta (Wed, 22 Mar 2017 11:42:21 GMT):
@davidkel. Ok, I'll do that.

davidkel (Wed, 22 Mar 2017 13:08:43 GMT):
@elisabetta never seen that sort of error before. How are you running fabric ?

elisabetta (Wed, 22 Mar 2017 13:09:18 GMT):
@davidkel: I can't replicate yesterday's problem any longer. I've started from a VM that is the same as I used yesterday. I now get directly the error above.

elisabetta (Wed, 22 Mar 2017 13:10:56 GMT):
I'm running the peer natively in another VM in another host than the VM with composer cli

davidkel (Wed, 22 Mar 2017 13:11:38 GMT):
@elisabetta is it possible that whatever ports you have configured in your connection profile something else is now listening on that port rather than the peer ?

elisabetta (Wed, 22 Mar 2017 13:12:52 GMT):
I don't think so, I can run REST apis against that peer on that port

elisabetta (Wed, 22 Mar 2017 13:13:15 GMT):
but I'll double check..

davidkel (Wed, 22 Mar 2017 13:16:50 GMT):
@elisabetta what level of fabric are you running ? and just out of interest could you post your connection profile

@tlplickebaum thanks for the screenshots - the first one is indicating there's no xcode - some of the modules that are dependencies of Fabric-Composer have native code that needs to be compiled . so a C compiler is required.

@bonen that type of error can mean that it isn't able to connect to the running fabric. The comment about Composer Playground is because we deploy a version of it to bluemix but as it only supports the web connection profile you can't use it to try to connect to your bluemix instance of fabric

sstone1 (Thu, 23 Mar 2017 17:49:15 GMT):
Uploading it to YouTube at the moment - will post the link in here when it's ready, and also update the GitHub agenda page: https://github.com/fabric-composer/fabric-composer/wiki/Meeting-23rd-March-2017

tennenjl (Thu, 23 Mar 2017 17:50:41 GMT):
@sstone1 much obliged!

sstone1 (Thu, 23 Mar 2017 18:18:42 GMT):
Video still processing - will be later this evening.

sstone1 (Thu, 23 Mar 2017 18:21:07 GMT):
@here in the meantime, our next biweekly community call is next Thursday 30th March. Please suggest any topics you'd like to cover on the call! Any topic you want... whether it's big or small, and we can go as high level or low level as you like :)

atomkinson (Thu, 23 Mar 2017 18:24:57 GMT):
Has anyone tried building composer functions in Typescript? Just started thinking about this today during the call, so I'm not sure if VS Code would handle the transcompile automatically (I think it will) or if something would need to be built into the composer plugin to run tsc first.

gauthampamu (Thu, 23 Mar 2017 18:29:04 GMT):
I noticed the documentation changed on https://fabric-composer.github.io/index.html but I don't see any posts related to this update. Do we posting on the channel when we update the documentation or is there any other channel where we post updates to documentation.

sstone1 (Thu, 23 Mar 2017 18:30:28 GMT):
@atomkinson funny you ask, @xuanyue202 has been looking at additional language support. It's something we could discuss on next weeks call. See https://github.com/fabric-composer/fabric-composer/issues/554 for information.

sstone1 (Thu, 23 Mar 2017 18:31:16 GMT):
As far as I'm aware nobody has tried it. But you should be able to do the transpilation client side, including the resulting .js files in that archive.

atomkinson (Thu, 23 Mar 2017 18:31:52 GMT):
@sstone1 Thanks! I'll take a look at 554 and if I can find some time I'll look into it too.

sstone1 (Thu, 23 Mar 2017 18:32:26 GMT):
Until we get native Node.js chaincode support in base Fabric I think it would be prohibitively difficult to run most transpilers on the chaincode side during deployment. It may be quicker to focus on that first.

atomkinson (Thu, 23 Mar 2017 18:33:38 GMT):
yea.. I would tend to agree. Client side transpile makes most sense, and I'm pretty sure that at least VSCode will handle it for you if you include the right things, like a tsconfig file and such.

sstone1 (Thu, 23 Mar 2017 18:33:52 GMT):
@gauthampamu we've been working on the docs updates, these are in GitHub issues - appreciate we haven't said much in here though. We have a specialized information developer @EdProsser in the team who's ripping up the old docs (written by developers) and making them much easier to consume.

sstone1 (Thu, 23 Mar 2017 18:35:07 GMT):
Would love to hear what you think of the new docs!

atomkinson (Thu, 23 Mar 2017 18:35:34 GMT):
@sstone1 The bit in the call today where you covered the Angular app made me thing about it. :-) (BTW, was that Angular 1 or 2?)

sstone1 (Thu, 23 Mar 2017 18:35:50 GMT):
Angular 2 with Typescript ;)

sstone1 (Thu, 23 Mar 2017 18:36:17 GMT):
All of the playground/UI code is also written in Angular 2 with Typescript

sstone1 (Thu, 23 Mar 2017 20:14:18 GMT):

Wow - just in time - thanks for the recording. I'm just getting started, and need to convert a fabric V0.4 to V1.0. Since I assume it needs a re-write, I thanks you for saving me time :)

No problem @jvkatzman, let us know how you get on!

uber.twin (Fri, 24 Mar 2017 09:00:32 GMT):
hi, sorry for insisting on this matter, is there a way to resubmit a transaction, i.e. have the "onTransaction" function execute more than one time for the same transaction object?

sstone1 (Fri, 24 Mar 2017 09:09:53 GMT):
@uber.twin how are you submitting the transaction? If it fails, you should just be able to call submitTransaction() or do the REST POST call again?

uber.twin (Fri, 24 Mar 2017 09:14:57 GMT):
I'd like to be able to resubmit it again from within the runtime

uber.twin (Fri, 24 Mar 2017 09:15:39 GMT):
it doesn't fail technically, it just can't execute because of some business rules

uber.twin (Fri, 24 Mar 2017 09:16:12 GMT):
e.g. insufficient funds

uber.twin (Fri, 24 Mar 2017 09:16:57 GMT):
later on, other transactions makes the funds available for the first transaction. then I'd expect to be able to resubmit the first transaction with a runtime call

sstone1 (Fri, 24 Mar 2017 09:19:44 GMT):
You can't do that. Nothing is persisted if a transaction fails, we throw an exception and the transaction gets rolled back by Fabric.

uber.twin (Fri, 24 Mar 2017 09:21:34 GMT):
but it doesn't "fail" from a technical point of view, it sets a pending state on an asset transfer

uber.twin (Fri, 24 Mar 2017 09:22:39 GMT):
because there is not enough of that asset available at the current time

uber.twin (Fri, 24 Mar 2017 09:22:51 GMT):
but it may become available

uber.twin (Fri, 24 Mar 2017 09:23:26 GMT):
then I'd like to be able to rerun the "onTransaction" routine

uber.twin (Fri, 24 Mar 2017 09:24:34 GMT):
form the runtime, as I detect the required asset quantity is available

sstone1 (Fri, 24 Mar 2017 09:25:28 GMT):
Where would the "pending state" property be stored?

uber.twin (Fri, 24 Mar 2017 09:27:57 GMT):
at the asset level

sstone1 (Fri, 24 Mar 2017 09:28:53 GMT):
At the moment, I think the only way to do it is to submit the transaction again, or... you could model the transfer as an asset itself, and have two transactions: SubmitTransfer and ResubmitTransfer

sstone1 (Fri, 24 Mar 2017 09:29:32 GMT):
SubmitTransfer would create a Transfer asset with all the details in, and check to see if enough of the asset is available - if so, perform the transfer, if not, set the Transfer to pending.

sstone1 (Fri, 24 Mar 2017 09:29:48 GMT):
ResubmitTransfer would take a reference to an existing Transfer asset and reprocess it.

sstone1 (Fri, 24 Mar 2017 09:30:12 GMT):
You could move the common JavaScript code into a utility function and call it from the onSubmitTransfer and onResubmitTransfer JavaScript functions.

uber.twin (Fri, 24 Mar 2017 09:30:36 GMT):
alright, thank you

uber.twin (Fri, 24 Mar 2017 09:31:34 GMT):
so submitting a transaction can be done only through the client API, right?

sstone1 (Fri, 24 Mar 2017 09:31:58 GMT):
Through the JavaScript client API (composer-client) or through the REST API

uber.twin (Fri, 24 Mar 2017 09:32:06 GMT):
yes

uber.twin (Fri, 24 Mar 2017 09:33:02 GMT):
something else, are there any plans to be able to define runtime timers?

sstone1 (Fri, 24 Mar 2017 09:33:39 GMT):
You mean to fire transactions based on a cron job?

sstone1 (Fri, 24 Mar 2017 09:33:39 GMT):
You mean to fire transactions based on an automated timer or cron job?

uber.twin (Fri, 24 Mar 2017 09:33:47 GMT):
or is it possible at the present moment?

uber.twin (Fri, 24 Mar 2017 09:33:55 GMT):
yes

sstone1 (Fri, 24 Mar 2017 09:34:34 GMT):
Not possible using just the chaincode today. We'd need Fabric support for that feature to be able to build it into our chaincode.

uber.twin (Fri, 24 Mar 2017 09:34:35 GMT):
not necessarily fire cto transactions, but run cron jobs

uber.twin (Fri, 24 Mar 2017 09:34:47 GMT):
ok

uber.twin (Fri, 24 Mar 2017 09:34:59 GMT):
thank you again

sstone1 (Fri, 24 Mar 2017 09:35:15 GMT):
However you could set up an external timer that drives the client API to submit a transaction at a set interval.

sstone1 (Fri, 24 Mar 2017 09:36:51 GMT):
I'm pretty sure that you could use something like OpenWhisk or Amazon Lambda functions to do that.

uber.twin (Fri, 24 Mar 2017 09:36:58 GMT):
yes, but then I'll need to have a special client role

uber.twin (Fri, 24 Mar 2017 09:37:40 GMT):
which will condition the runtime functionality

sstone1 (Fri, 24 Mar 2017 09:38:04 GMT):
Yep, you would have to have a "scheduler" participant

xuanyue202 (Fri, 24 Mar 2017 11:07:21 GMT):
@sstone1 looking forward to the discussion on the language support thing next week. Although the meeting is too late for me, I will go to watch the recording.

xuanyue202 (Fri, 24 Mar 2017 11:25:37 GMT):
@atomkinson Client-side transpiling is a quick solution. But chaincode-side transpilation also has its advantage, (although I admit there is a long way to go). First, it makes the bna more readable and manageable in Playground. Moreover, the current version of JS scripts require transaction functions to be global functions with comment annotations, which might not be doable for all the transpilers.

@sstone1 I define my business network locally (CTO & JS files). What's the best lace to deploy it between these two interfaces ?

annbnn (Fri, 24 Mar 2017 12:41:51 GMT):
And how to do if I want to simulate a participant using an IP address (or a server) in USA and another participant using an IP address (or a server) in Switzerland for example ?

annbnn (Fri, 24 Mar 2017 12:42:27 GMT):
Does Fabric composer allow to do that ?

annbnn (Fri, 24 Mar 2017 12:42:54 GMT):
Or I can only run my business network locally ?

norinos (Fri, 24 Mar 2017 13:10:55 GMT):
Hi. I am trying Fabric-composer v0.5.5. Which should I use Fabric v0.6 or v1.0?

sstone1 (Fri, 24 Mar 2017 14:08:01 GMT):
@annbnn the first picture is our old UI, which will be removed soon. The second picture is our new UI, or "Playground". The playground has features that allow you to import/export business network definitions (CTO, JS & ACL files) to and from your local file system.

sstone1 (Fri, 24 Mar 2017 14:09:15 GMT):
Fabric Composer can connect to a Hyperledger Fabric instance running anywhere; you simply need to provide the connection details in the connection profile. In your example, there would be a "USA" connection profile used by the USA participant with the URL of the USA Fabric peer node, and a "Switzerland" connection profile used by the Swiss participant with the URL of the Switzerland Fabric peer node.

sstone1 (Fri, 24 Mar 2017 14:10:14 GMT):
@norinos you should use Fabric v0.6 at this time. Anything you develop using Fabric Composer on top of Fabric v0.6 will run on Fabric v1.0 as well.

sstone1 (Fri, 24 Mar 2017 14:10:45 GMT):
The support for Fabric v1.0 is coming along nicely and we will be documenting how to use it soon, but it will be a little longer before we get our getting started guide and playground installation updated.

annbnn (Fri, 24 Mar 2017 14:12:39 GMT):
@sstone1 Thank you.

annbnn (Fri, 24 Mar 2017 14:12:50 GMT):
By the way, I saw this *namespace net.biz.digitalPropertyNetwork*

annbnn (Fri, 24 Mar 2017 14:12:58 GMT):
How do you define your namespace ?

annbnn (Fri, 24 Mar 2017 14:13:14 GMT):
'use strict'; /** * Process a property that is held for sale * @param {net.biz.digitalPropertyNetwork.RegisterPropertyForSale} propertyForSale the property to be sold * @transaction */ function onRegisterPropertyForSale(propertyForSale) { console.log('### onRegisterPropertyForSale ' + propertyForSale.toString()); propertyForSale.title.forSale = true; returAssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) { return result.update(propertyForSale.title); } ); }

annbnn (Fri, 24 Mar 2017 14:15:58 GMT):
@sstone1 I got this error when I tried to test the file above

annbnn (Fri, 24 Mar 2017 14:15:59 GMT):

O the Playground UI.

annbnn (Fri, 24 Mar 2017 14:16:43 GMT):
on the Playground UI.

Jakeeyturner (Fri, 24 Mar 2017 14:17:40 GMT):
Your namespace is defined in your cto file. That error is because you're missing an 'n'

Jakeeyturner (Fri, 24 Mar 2017 14:18:11 GMT):
```returAssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) {``` should be ```return AssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) {```

Jakeeyturner (Fri, 24 Mar 2017 14:18:11 GMT):
```returAssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) {```

Jakeeyturner (Fri, 24 Mar 2017 14:18:34 GMT):
should be

Jakeeyturner (Fri, 24 Mar 2017 14:18:40 GMT):
```return AssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) {```

annbnn (Fri, 24 Mar 2017 14:19:57 GMT):
@Jakeeyturner Thank you

annbnn (Fri, 24 Mar 2017 14:20:09 GMT):
The definition is just writting *namespace net.biz.digitalPropertyNetwork*

annbnn (Fri, 24 Mar 2017 14:20:11 GMT):
right ?

sstone1 (Fri, 24 Mar 2017 14:20:21 GMT):
@annbnn you are in complete control of the namespaces that you want to use, you can pick one suitable for your business network or organization

annbnn (Fri, 24 Mar 2017 14:21:12 GMT):
How the definition is done ?

annbnn (Fri, 24 Mar 2017 14:21:28 GMT):
You can choose any name you want as a namespace ?

annbnn (Fri, 24 Mar 2017 14:22:44 GMT):
Another question. How to cancel/delete files on the Fabric composer Playground if you want to start from scratch ?

sstone1 (Fri, 24 Mar 2017 14:24:48 GMT):
Correct, you can choose any name you want as a namespace.

sstone1 (Fri, 24 Mar 2017 14:25:06 GMT):
We are working on delete.

sstone1 (Fri, 24 Mar 2017 14:25:17 GMT):
If you want to start from scratch, press the Import button in the bottom left.

sstone1 (Fri, 24 Mar 2017 14:25:26 GMT):
You can them Import any of our predefined sample business networks.

annbnn (Fri, 24 Mar 2017 14:35:22 GMT):

uber.twin (Fri, 24 Mar 2017 15:40:25 GMT):
hi, does the chaincode runtime allow js classes and node modules definitions?

sstone1 (Fri, 24 Mar 2017 15:45:09 GMT):
@uber.twin no, it doesn't. We use Otto, which is an ES5 compliant JavaScript interpreter written in Go. It does not support classes, and it does not support modules from npm.

sstone1 (Fri, 24 Mar 2017 15:45:32 GMT):
You might have some luck using a transpiler like Babel to go from ES6/7 to ES5 but that's not been tried.

jdockter (Fri, 24 Mar 2017 15:59:24 GMT):
@sstone1 you guys pushing out any stable updates today?

uber.twin (Fri, 24 Mar 2017 16:00:45 GMT):
@sstone1 Does ES5 have any import mechanism allowing to structure code in multiple js files?

sstone1 (Fri, 24 Mar 2017 16:02:25 GMT):
@jdockter no, we're going to cut one early next week instead

sstone1 (Fri, 24 Mar 2017 16:03:30 GMT):
@uber.twin ES5 doesn't have any such feature, but for Composer all functions in all JS files in the business network definition can be called from anywhere.

sstone1 (Fri, 24 Mar 2017 16:03:53 GMT):
So you can have a utility.js with a utilFunction() that you can call from transactions.js in onTransferAsset()

uber.twin (Fri, 24 Mar 2017 16:04:57 GMT):
ok, that sounds good, thank you

Just a question. The zip file to import to deploy a model using the fabric composer playground contains CTO, JS and package.son file. Right ?

annbnn (Mon, 27 Mar 2017 12:25:05 GMT):
Does some one here knows in few sentences the full process to deploy a business network using the fabric composer playground ?

annbnn (Mon, 27 Mar 2017 12:26:05 GMT):

annbnn (Mon, 27 Mar 2017 12:26:47 GMT):
I wrote code for CTO and JS files.

annbnn (Mon, 27 Mar 2017 12:27:00 GMT):
The import does not work.

dselman (Mon, 27 Mar 2017 12:33:16 GMT):
Put the JS files under a folder called `lib`, put the CTO files under a folder called `models`. Put the package.json file in the root. Use the `composer archive create` command to create the BNA file.

annbnn (Mon, 27 Mar 2017 12:41:26 GMT):
@dselman Thank you. Which files do I need to import after this process on the playground ?

dselman (Mon, 27 Mar 2017 12:41:48 GMT):
You import the BNA file, using the Import/Replace button

hi, I understood the composer runtime is an ES5 implementation. but I see it makes use of promises and I thought promises come with ES6. So after all, is there a native Promise object in composer runtime?

sstone1 (Tue, 28 Mar 2017 08:06:19 GMT):
Just a reminder - there is a community meeting this Thursday (30th March). The timings and dial in details are on the Wiki here: https://github.com/fabric-composer/fabric-composer/wiki/Meeting-30th-March-2017. Please let me know if you have any suggestions that you'd like to see discussed on the agenda :)

bonen (Tue, 28 Mar 2017 08:14:57 GMT):
hi, Is my assumption correct that assets can only be created/updated/deleted trough transactions and not directly from within application code / the command line?

sstone1 (Tue, 28 Mar 2017 08:20:50 GMT):
No, there is a full CRUD API for assets and participants

dselman (Tue, 28 Mar 2017 08:21:03 GMT):
You can CRUD assets and participants via the REST API or JS client API, or the runtime API.

dselman (Tue, 28 Mar 2017 08:21:21 GMT):
heh...

bonen (Tue, 28 Mar 2017 08:31:07 GMT):
Why do you have the concept of transactions then? I was currently putting the complex logic (conditions), to manipulate assets, in the transaction definitions. If participants can omit the transaction and directly manipulate an asset, I need to capture all that same conditions in the ACL file. But the rather complex condition logic I currently use can't be expressed in ACL. Or is there a way to only e.g. allow an asset to be created via a certain transaction?

bonen (Tue, 28 Mar 2017 08:32:52 GMT):
Or do I miss a point here:) ?

dselman (Tue, 28 Mar 2017 08:36:38 GMT):
@bonen I think you raise a valid point regarding access control. Transactions allow you to do much more than CRUD operations on a single asset/participant -- they can perform arbitrary updates to sets of assets etc. They also provide looser coupling between the client (transaction submitter) and the server (transaction processor).

bonen (Tue, 28 Mar 2017 08:43:55 GMT):
Ok, clear! Would be nice then if you could optionally restrict access to an asset by only allowing certain transactions to operate on it, right? Do you think that is currently possible somehow?

uber.twin (Tue, 28 Mar 2017 08:47:36 GMT):

georgeormrod@gmail.com (Tue, 28 Mar 2017 09:49:42 GMT):
Hi guys, does the primary key (identifier) of a model object need to be in a special format? For example, `owner = factory.newInstance('net.biz.digitalPropertyNetwork', 'Person', 'PID:1234567890');` the final argument of newInstance has PID: followed by a identifier. I only ask because I'm getting the following error when trying to add a asset to a registry `Error: Invalid or missing identifier for Type TestAsset in namespace test.net.chaincode`

uber.twin (Tue, 28 Mar 2017 09:50:57 GMT):
I humbly insist: is there any way to get an idea about the location of a syntax error in my chaincode? The runtime error conveys as much details about it as I'd expect from the Oracle of Delphi.

dselman (Tue, 28 Mar 2017 09:51:11 GMT):
@georgeormrod@gmail.com No, it just has to be a non empty string.

georgeormrod@gmail.com (Tue, 28 Mar 2017 09:52:47 GMT):
@dselman Thanks, I can rule that out

dselman (Tue, 28 Mar 2017 09:53:34 GMT):
@uber.twin the easiest way to develop/debug transaction processor functions at the moment is to write a Node.js unit test. We are working on better testing support inside Playground at the moment. You can see an example unit test here: https://github.com/fabric-composer/sample-networks/blob/master/packages/carauction-network/test/CarAuction.js

dselman (Tue, 28 Mar 2017 09:54:42 GMT):

Jakeeyturner (Tue, 28 Mar 2017 09:55:43 GMT):
@uber.twin I'm not sure how you're developing, but if you're not already, it might be worth using either the Atom or VSCode plugin for syntax highlighting

dselman (Tue, 28 Mar 2017 10:00:07 GMT):
That looks ok -- how are you adding `asset` to the registry?

georgeormrod@gmail.com (Tue, 28 Mar 2017 10:01:54 GMT):
`assetRegistry = businessNetworkConnection.getAssetRegistry("test.net.chaincode.TestAsset")` `assetRegistry.add(asset);`

dselman (Tue, 28 Mar 2017 10:16:41 GMT):
That looks ok as well. If you post your BNA file and code I can take a deeper look.

dselman (Tue, 28 Mar 2017 10:18:47 GMT):
getAssetRegistry returns a promise... E.g. see https://github.com/fabric-composer/sample-networks/blob/master/packages/carauction-network/test/CarAuction.js

georgeormrod@gmail.com (Tue, 28 Mar 2017 10:33:18 GMT):

@georgeormrod@gmail.com `composer-rest-server` is here: https://github.com/fabric-composer/fabric-composer/tree/master/packages/composer-rest-server is that what you are referring to?

dselman (Tue, 28 Mar 2017 16:16:29 GMT):
@uber.twin log output should go to the Docker container for the chaincode.

"It is not possible to add Connection Profiles in the Web Playground version of Fabric Composer. If you like what you see, you can install a a local version of Fabric Composer. The local version offers the same UI, or a CLI experience, and can be used to deploy Business Network Definitions to running Hyperledger Fabric instances." I am running composer playground on my local machine but still not able to create connection profile to add the fabric environment.

they will be soon - hopefully next week

anyone else notice there are issues installing current versions of the composer modules? `No compatible version found: fabric-ca-client@^0.1.2` specified as a dependency of `composer-connector-hlfv1`... I get this trying to install the rest-server module or loopback-connector

shamckm (Wed, 29 Mar 2017 07:03:34 GMT):
I followed the fabric composer installation instructions, getting started instructions, and then "How to generate a starter application" instructions (https://fabric-composer.github.io/applications/genapp.html). I use the command "yo fabric-composer:angular" to generate a new angular app. A new directory is created and I go into it and type "npm start". It started up the Angular web server for me and so I use a browser and go to "localhost:4200" to access the app screen. When I click "LandTitle", I should be able to see the 2 records created during the "getting started" steps. However, there is no record there. Any idea what went wrong in my set up?

dselman (Wed, 29 Mar 2017 07:26:13 GMT):
did you run `npm test` on the getting started? That should have started a Fabric and created the records.

davidkel (Wed, 29 Mar 2017 07:36:41 GMT):
@pospi the 0.5.5 release should be using newer levels of the fabric-ca-client, as I guess the older versions of fabric-ca-client have been removed from npm. What version of composer-rest-server are you using ?

shamckm (Wed, 29 Mar 2017 07:44:33 GMT):
@dselman Yes, I did run the "npm test" and can see the 2 land titles in the output

Is your Fabric still running?

@davidkel I'm not using any version yet, was just trying to install it from NPM for some testing.

Jakeeyturner (Wed, 29 Mar 2017 08:12:21 GMT):
@shamckm If the application can't load any assets, then it means either something is wrong with Fabric, or the application has been supplied some incorrect details. So, first try deleting your application and generating it again. Then can you post your terminal output (including your answers to each of the questsions).

davidkel (Wed, 29 Mar 2017 08:23:46 GMT):
@pospi Not sure what is going on here for you. For me install of the composer rest server pulls down 0.5.5 and also pulls down 0.5.5 of the composer-connector-hlfv1 module which is using a newer version of fabric-ca-client (0.2.3)

pospi (Wed, 29 Mar 2017 08:40:42 GMT):
honestly, I don't know. Can't see anything because it's failing in the NPM download step

davidkel (Wed, 29 Mar 2017 08:44:52 GMT):
@pospi do you get the same problem if you do npm install composer-cli ?

pospi (Wed, 29 Mar 2017 08:47:29 GMT):
yep

davidkel (Wed, 29 Mar 2017 08:50:56 GMT):
@pospi could you try `npm show composer-connector-hlfv1`, `npm show composer-admin` 'npm show composer-rest-server` and look at the 'dist-tags` field for all. the show for composer-connector-hlfv1 should also list the fabric-ca-client dependency version

pospi (Wed, 29 Mar 2017 09:00:11 GMT):
connector-hlfv1: `'dist-tags': { unstable: '0.5.6-20170329065851', latest: '0.5.5' }` `dependencies: { 'composer-common': '^0.5.5', 'composer-runtime-hlfv1': '^0.5.5', 'fabric-client': '0.2.3', 'fabric-ca-client': '0.2.3', 'fs-extra': '^1.0.0', semver: '^5.3.0', temp: '^0.8.3', 'thenify-all': '^1.6.0', uuid: '^3.0.1' },` composer-admin: `'dist-tags': { latest: '0.5.5', unstable: '0.5.6-20170329065851' }`

pospi (Wed, 29 Mar 2017 09:01:36 GMT):
fabric-ca-client is `'dist-tags': { latest: '1.0.0-alpha.0', unstable: '1.0.0-snapshot.6' }`

shamckm (Wed, 29 Mar 2017 09:03:40 GMT):
@Jakeeyturner I caught an error message when I run the "npm start" command: (node:9141) UnhandledPromiseRejectWarning: Unhandled promise rejection (rejection id: 1): Error: Failed to load connector module "composer-connector-hlf" for connection profile "defaultProfile"

davidkel (Wed, 29 Mar 2017 09:09:39 GMT):
@pospi for fabric-ca-client, 0.2.3 still exists even though the latest has a different tag. You've cleared your cache so I'm not sure why you seem to be pulling older versions down. composer-rest-server depend on composer-client and composer-admin and these depend on composer-connector-hlfv1. Could you try explicitly installing 0.5.5 of the composer-rest-server `npm install composer-rest-server@0.5.5` and see if that works ?

@dselman @Jakeeyturner I really can't find the logging supposed to be generated by the chaincode "console.log()" statements. Could you please confirm that it should be included in the " docker logs -f " output?

Jakeeyturner (Wed, 29 Mar 2017 09:50:30 GMT):
You should see it in the chaincode container (If you do a `docker ps` it'll be the container where the name is 'dev-vp0-...')

Jakeeyturner (Wed, 29 Mar 2017 09:50:49 GMT):
Can you confirm this @mbwhite?

uber.twin (Wed, 29 Mar 2017 09:52:33 GMT):

mbwhite (Wed, 29 Mar 2017 09:53:18 GMT):
@Jakeeyturner correct yes

Jakeeyturner (Wed, 29 Mar 2017 09:56:19 GMT):
Thanks Matthew. @uber.twin if you do `docker ps -f status=running` you should see some docker containers running. One of them will be named `dev-vp0-HASH_HERE`. If you do a `docker logs -f HASH_HERE` you can follow the container and read the logs as things happen

Jakeeyturner (Wed, 29 Mar 2017 09:56:19 GMT):
Thanks Matthew. @uber.twin if you do `docker ps -f status=running` you should see some docker containers running. One of them will be named `dev-vp0-RANDOM_HASH`. If you find the ID of that container, then you can do a `docker logs -f ID_HERE` you can follow the container and read the logs as things happen

uber.twin (Wed, 29 Mar 2017 09:59:27 GMT):
ok, I was looking at the wrong peer(hyperledger/fabric-peer)

uber.twin (Wed, 29 Mar 2017 10:00:06 GMT):
the "dev-vp0-" does have it

uber.twin (Wed, 29 Mar 2017 10:00:12 GMT):
thank you

uber.twin (Wed, 29 Mar 2017 10:00:45 GMT):
I didn't expect the peers to be spawn automatically

uber.twin (Wed, 29 Mar 2017 10:01:35 GMT):
at the runtime startup, I could notice only two peers

uber.twin (Wed, 29 Mar 2017 10:02:12 GMT):
then, as I deploy the network, the "dev-vp0-" comes up also

uber.twin (Wed, 29 Mar 2017 10:03:55 GMT):
again, I thought the runtime peers instances are not dynamic

uber.twin (Wed, 29 Mar 2017 10:04:20 GMT):
is there a specification regarding the conditions a new peer comes up?

uber.twin (Wed, 29 Mar 2017 10:04:40 GMT):
and what determines it

pospi (Wed, 29 Mar 2017 10:08:32 GMT):
@uber.twin I believe that's how a new Composer business network is deployed- as a peer docker container running the chaincode

elisabetta (Wed, 29 Mar 2017 10:10:50 GMT):
@davidkel: just installed `composer-rest-server` with another user other than root, and the installation completes successfully, without having to specify --unsafe-perm! :tada:

elisabetta (Wed, 29 Mar 2017 10:14:11 GMT):

shamckm (Wed, 29 Mar 2017 10:14:17 GMT):
@Jakeeyturner removing the "node_modules" directory and running "npm install" did the job. The error message disappeared and I can now see the 2 land titles. Thanks for your help!

elisabetta (Wed, 29 Mar 2017 10:14:23 GMT):
It works well if I run it as root

uber.twin (Wed, 29 Mar 2017 10:15:39 GMT):
@Jakeeyturner @mbwhite @pospi it was confusing because, as I deploy the docker-compose.yml, only two peers are active:

uber.twin (Wed, 29 Mar 2017 10:15:41 GMT):
713976248b95 hyperledger/fabric-peer d97a2f80ce0e hyperledger/fabric-membersrvc

uber.twin (Wed, 29 Mar 2017 10:16:38 GMT):
but after I deploy the network, another peer comes up, e.g.:

uber.twin (Wed, 29 Mar 2017 10:16:38 GMT):
1cb8256002e7 dev-vp0-210ce3d3d885a302ae98dbcce13fe32f5054842190dfe9afa58b5f61f84263ad

uber.twin (Wed, 29 Mar 2017 10:17:31 GMT):
and only this last peer logs the chaincode output

uber.twin (Wed, 29 Mar 2017 10:19:59 GMT):
and when I redeploy the network, yet another peer appears:

uber.twin (Wed, 29 Mar 2017 10:20:01 GMT):
bc89f5236f6b dev-vp0-b7f4dde7d390648e94c629b276d1827d7876d680170593fdce6c0267346a9fa2

uber.twin (Wed, 29 Mar 2017 10:20:53 GMT):
so that means each network deploy/redeploy instantiates a new peer?

uber.twin (Wed, 29 Mar 2017 10:21:45 GMT):
by redeploy I mean undeploy/ deploy with the same business network id

Jakeeyturner (Wed, 29 Mar 2017 10:27:47 GMT):
So the undeploy Composer-CLI command will remove the chaincode container. And when you deploy a business network, a chaincode container is created

sstone1 (Wed, 29 Mar 2017 10:32:19 GMT):
Those are not peer containers - they are chaincode containers that are owned by the individual peers.

Hi guys, how is a transaction called in `composer-client`? I'm getting an error when running `transactionRegistry.add(transaction)`, does the logic need to be defined before I run it?

davidkel (Wed, 29 Mar 2017 11:27:31 GMT):
@georgeormrod@gmail.com to submit a transaction to a business network you need to define your transaction object and then use the submitTransaction.

@Jakeeyturner @sstone1 tanks for the explanations; however, when I do undeploy, the existing chaincode container stays on and a new one is added when deploying it back

uber.twin (Wed, 29 Mar 2017 11:34:51 GMT):
this is my "docker ps: output after a first business network deploy 1cb8256002e7 dev-vp0-210ce3d3d885a302ae98dbcce13fe32f5054842190dfe9afa58b5f61f84263ad 713976248b95 hyperledger/fabric-peer d97a2f80ce0e hyperledger/fabric-membersrvc

@uber.twin I believe that is the expected behaviour

uber.twin (Wed, 29 Mar 2017 12:16:36 GMT):
sure, just a litte confusing. the old chaincode container, which was spawn by a previous deployment, stays on but it seems inactive. only the new chaincode container rolls when a transaction hits the newly deployed business network

Does Fabric Composer accept Bluemix credentials for the Connection Profile yet?

davidkel (Wed, 29 Mar 2017 12:51:57 GMT):
@sbrakev it does except for composer-playground. See http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service

jdockter (Wed, 29 Mar 2017 12:51:57 GMT):
@sbrakev v0.6? or v1.0?

sbrakev (Wed, 29 Mar 2017 12:52:30 GMT):
Thanks guys. At this point I'm cool with either @jdockter but ideally V1.0

davidkel (Wed, 29 Mar 2017 12:54:19 GMT):
@sbrakev composer-ui will only work with v0.6 and won't have v1.0 support added to it

sbrakev (Wed, 29 Mar 2017 12:54:57 GMT):
Not yet but should have support later....right

davidkel (Wed, 29 Mar 2017 12:57:03 GMT):
@sbrakev not in composer-ui as it is going to be replaced by composer-playground but for now. composer-playground only supports the web profile currently so to connect to bluemix you would need to use composer-ui for now to v0.6

sbrakev (Wed, 29 Mar 2017 12:59:57 GMT):
Okay so the plan is to have composer-playground become the de facto way of doing UI based editing with composer-ui being phased out as a local deployment?

jdockter (Wed, 29 Mar 2017 13:07:41 GMT):
@sbrakev currently there are two flavors of a composer web ui, one is called composer-ui (older version) and the second is composer-playground (new version with lots of extra functionality and design team touch :) ...both can be installed locally if you change up the docker-compose.yml to point to specific docker images (https://hub.docker.com/u/fabriccomposer/) ...only composer-ui has support for remote connection profiles, of which bluemix could be one, at the v0.6 version

Jakeeyturner (Wed, 29 Mar 2017 13:12:54 GMT):
@sbrakev Yes, Composer Playground at some point once we've added all the functionality will be the main UI-based editing environment. This will replace Composer UI entirely

Hi All. I have a strange problem locally. I started to use the fabric composer playground. As a trial, took the business network digitalproperty-network and basic-sample-network. Updating assets work well when I use the files by Authenticating my self With GitHub. However, when I use the same files locally on my computer and I try to import them, every thing works, but there is no update on assets. Why ? Some one can help me please ?

DennisM330 (Wed, 29 Mar 2017 20:58:32 GMT):
Installed the Fabric Composer Playground locally. Get this error when I try to access localhost:8080 "Error: Expected "rule", comment, end of line or whitespace but "A" found. Line 4 column 1". Also tried to add a file - select model file (.cto file), but add button is greyed out

DennisM330 (Wed, 29 Mar 2017 21:38:26 GMT):
Appears the sample network is not automatically imported on the playground. I can do an import/replace using the samples from Github though. So how do you create a new business network from scratch like you can from the composer-ui?

DennisM330 (Wed, 29 Mar 2017 21:43:43 GMT):
My mistake, importing the bna only works on the playground in Bluemix

DennisM330 (Wed, 29 Mar 2017 22:09:08 GMT):
I installed composer-playground using npm and it appears to work much better than installing with Docker, seems to be some differences in the docker image

For example I am using the digitalPropertyNetwork example. I can get the exact LandTitle by ?filter={"where":{"titleId":"xxx"}} but unable to do so when the filter is {"where":{"owner":"yyy"}} (it responses with message "The specified filter does not match the identifier in the model")

@tonyltf we do not support this at the moment. currently you can only query assets and participants by their ID. we will be looking to exploit the CouchDB support introduced with v1.0 through composer to enable this - we're calling it "complex query support".

hi all: If the registry does not exist it results in an : Unhandled rejection: Error: egistry signature not found! How can I make it result into an error that does not add the transaction?? Related question, if an error occurs at the end of a transaction function, is every update to assets before that automatically reversed?? function onSign(transaction) { return getAssetRegistry('org.notarynodes.bloqNetwork.Signature') .then(function (registry) { var factory = getFactory(); var signatureId = transaction.signer.getIdentifier().toString() + "#"+ transaction.assetType + "#" + transaction.assetId; var newSignature = factory.newResource('org.notarynodes.bloqNetwork', 'Signature', signatureId); newSignature.signer = transaction.signer; newSignature.timestamp = new Date(); return registry.add(newSignature); } ) .catch(function (error) { throw new Error("Registry signature not found!"); }); }

dselman (Fri, 31 Mar 2017 08:05:44 GMT):
Any exceptions thrown from a transaction processor function will cause the entire transaction to be rolled back, leaving no changes to the blockchain or world state.

bonen (Fri, 31 Mar 2017 09:39:53 GMT):
Ok thanks! Though the catched error thrown in the example above will not cause the transaction to fail.. when I inspect the playground console it calls it an unhandled rejection, instead of an error (what I would like it to be)..

Hi guys, quick one, does the models file name need to be the same as the business network identifier? Or does it just need to be in the models folder with a namespace annotation?

Jakeeyturner (Fri, 31 Mar 2017 13:45:27 GMT):
@annbnn the package.json file just needs to be a standard npm package.json file. At minimum it needs a package name, version and description. @georgeormrod@gmail.com The model files don't need to be named the same as the business network identifier. You're correct in that they must be in the models folder, and must have a namespace.

@dselman I saw the problem.

GrahamCharters (Mon, 03 Apr 2017 13:50:00 GMT):
Hi, I'm trying to update to the latest levels of everything. I've gone through the getting-started, etc and think I have the latest of everything. Hyperledger seems to start fine and the deployment, etc. However, when I try to start the composer-rest-server I get ? Enter your Fabric Connection Profile Name: defaultProfile ? Enter your Business Network Identifier : org.acme.vehicle.auction ? Enter your Fabric username : WebAppAdmin ? Enter your secret: DJY27pEnl16d 2017-04-03T12:47:55.104Z ERROR HFCConnection :login() Failed to set chaincode id on security context.

Jakeeyturner (Mon, 03 Apr 2017 13:53:36 GMT):
@GrahamCharters Can you output the contents of your defaultProfile connection.json file?

Jakeeyturner (Mon, 03 Apr 2017 13:54:16 GMT):
as it should refer to a network with the identifier `org.acme.vehicle.auction`

GrahamCharters (Mon, 03 Apr 2017 14:02:24 GMT):
@Jakeeyturner - thanks. Looks like I used to have that and now it's called "carauction-network". Specifying that name has got me further. Now have a client version mismatch I need to sort out... :/

GrahamCharters (Mon, 03 Apr 2017 14:10:09 GMT):
This is the error I'm now getting.

GrahamCharters (Mon, 03 Apr 2017 14:11:02 GMT):
Is the composer-cli the things being referred to as being at version 0.5.5? What is the "client" that's at 0.4.5?

GrahamCharters (Mon, 03 Apr 2017 14:11:02 GMT):
Is the composer-cli the things being referred to as being at version 0.5.5? Does anybody know what "client" is being referred to that's at 0.4.5?

GrahamCharters (Mon, 03 Apr 2017 14:13:54 GMT):
Looks like it might be my composer-rest-server...

dselman (Mon, 03 Apr 2017 14:31:42 GMT):
`npm uninstall -g composer-rest-server` followed by `npm install -g composer-rest-server`?

allenc2016 (Mon, 03 Apr 2017 14:47:04 GMT):
where can I find a sample Swagger document for the REST API created by the Composer?

GrahamCharters (Mon, 03 Apr 2017 14:56:18 GMT):

Today pulled down composer 5.6. Noticed within the composer-ui that the json is not being randomly generated/shown anymore for the Assets and Transactions. Though the random generated data does get shown for the Participants. Believe I previously had 5.4 where it got generated for everything. Is this an issue with 5.6?

dselman (Mon, 03 Apr 2017 21:52:09 GMT):
Can you please clear local storage and try again. You are using exactly the same business network in both v0.5.6 and v0.5.4?

klorenz (Mon, 03 Apr 2017 22:30:47 GMT):
Clear cache didn't resolve it. Yes, same exact business network. Appears the issue is where a Concept is involved. A simple Assets shows fine. An asset with a concept does not. Same applies for transactions.

MikeC711 (Tue, 04 Apr 2017 02:18:38 GMT):
Hope this is OK to log here: Looking at getting started tutorial for Fabric Composer Playground:

MikeC711 (Tue, 04 Apr 2017 02:30:20 GMT):
https://fabric-composer.github.io/tutorials/getting-started-playground.html .. I am on Xenial and have do manual preReq installs: docker -v -> Docker version 17.03.1-ce, build c6d412e docker-compose -v -> docker-compose version 1.11.2, build dfed245 node -v -> v6.10.1 npm -v -> 4.4.4 Containers came up great. I used the WebUI in one of the containers at http://Iocalhost:8080 ... defined 4 participants and 4 assets . As I try to submit trans ... for the new value I have put in random strings, let them generate strings, put in valid participant and asset keys ... but when I press submit, the submit button just blinks. I have to cancel to get out (or X) and I get no trans in the registry. I tried pulling basic logs from all 3 containers and don't see anything related. Tutorial is pretty sweet in generating simple one peer network ... but I don't see any details of Fabric Enrollment et al. So going back thru to see if I am missing key details. Is this a worthwhile sniff test of composer on a new Xenial VM? Thanks,

PS. The funny face in my problem report was actually an upper X and the close parenthesis. I was not trying to be cute, just trying to say that my other exit method was to hit the window exit key ... somehow Slack thought it was one of the emojis.

MikeC711 (Tue, 04 Apr 2017 11:56:08 GMT):
Possible DFU scenario (Dumb Darn User) ... I installed chrome and got same error, then went back and edit generated assets to be owned by created participants (seems like generation of asset used random participant IDs and if those participants were not created, logic often failed). I haven't figured out the full method to the madness ... but I can now create transactions on both chrome and firefox. So ignore for now ... I think I have enough to move on.

dselman (Tue, 04 Apr 2017 13:01:11 GMT):
@MikeC711 yes, the messages of type `does not exist Error: Object with ID 'assetId:4478' in collection with ID` mean that you have a reference to something that does not exist

dselman (Tue, 04 Apr 2017 13:01:34 GMT):
You need to make sure that the references in your model actually point to valid instances when you submit transactions

That usually means you have invalid certs in your certificate store

(i.e. certs for a different server)

Hi guys, can a super type be extended from another model in a network. If so, how is this done?

pospi (Tue, 04 Apr 2017 13:46:38 GMT):
Second @georgeormrod@gmail.com's question- when we try to do this Composer complains about the dots in the network namespace. We are trying to get a domain-specific model setup within a larger network using a setup similar to https://fabric-composer.github.io/business-network/model-publish.html but it doesn't seem to be documented yet..

mbwhite (Tue, 04 Apr 2017 13:55:22 GMT):
Hi, is

mbwhite (Tue, 04 Apr 2017 13:55:22 GMT):
Hi, is that from the same namespace or different?

dselman (Tue, 04 Apr 2017 13:58:51 GMT):
@georgeormrod@gmail.com yes, you need to `import` the type from namespace A into namespace B.

dselman (Tue, 04 Apr 2017 13:59:04 GMT):
@pop

dselman (Tue, 04 Apr 2017 13:59:16 GMT):
@pospi I don't understand, can you provide an example please

I think you might have just given us the answer we were hoping for ;)

uber.twin (Tue, 04 Apr 2017 14:13:39 GMT):
hi, is there a way to "upgrade" a deployed business network by uploading fresh chaincode but keep the old data registries intact?

Thanks @dselman :) is there a quick way to import all the types at once from a namespace, like `import everledger.network.*` instead of importing each type individually like `import everledger.network.BaseAsset` for example?

dselman (Tue, 04 Apr 2017 14:16:52 GMT):
No, not at this point.

georgeormrod@gmail.com (Tue, 04 Apr 2017 14:18:03 GMT):

Is the Fabric Composer playground supported on Mac or do you have to use only Ubuntu. https://fabric-composer.github.io/installing/prerequisites.html

dselman (Tue, 04 Apr 2017 15:33:37 GMT):

(it is supported)

dselman (Tue, 04 Apr 2017 16:14:39 GMT):
no

dselman (Tue, 04 Apr 2017 16:15:25 GMT):
You'll have to use a real Fabric to get a ledger that can be accessed across the network

@dselman hi, my fabric composer runtimes seem to produce a lot of logging and little by little, I'm running out of disk space

uber.twin (Wed, 05 Apr 2017 08:20:08 GMT):
a typical log entry(~20MB) looks like this, I got hundreds of them /var/lib/docker/aufs/diff/e4e4a2cfc12eaa60a4384c3392baabd3ed146c8e91494896ff0070a206a3a9ad/opt/gopath/bin/8ef51d2bdebfa031c324b7f3143ad5f70600971292b0564db303af0ee02077c1

uber.twin (Wed, 05 Apr 2017 08:20:47 GMT):
Is there a way to clean up these logs automatically when tearing down the runtimes?

uber.twin (Wed, 05 Apr 2017 08:24:50 GMT):
or can I simply clean up the entire "/var/lib/docker/aufs/diff/" directory and remain with a functional platform?

dselman (Wed, 05 Apr 2017 08:35:18 GMT):
Sounds like a Docker question... Try https://www.google.co.uk/search?q=clean+up+docker+logs

uber.twin (Wed, 05 Apr 2017 08:52:30 GMT):
any idea if the "/var/lib/docker/aufs/diff/" is used as an image repository too, besides as logs container?

uber.twin (Wed, 05 Apr 2017 08:53:45 GMT):
can I just clear it all ?

gauthampamu (Wed, 05 Apr 2017 08:54:44 GMT):
@dselman The installing link take you to the prereqs and the documentation site talks about Ubuntu and it only explains how to setup the prereqs. The documentation is under tutorials section but I was finally able to get it after trying all the different links. There is no way to search on the site. How to setup locally is explained under tutorials but there should be direct link or actually this information should be under installing section. https://fabric-composer.github.io/tutorials/getting-started-playground.html

bonen (Wed, 05 Apr 2017 08:59:46 GMT):
Hi all, In the chaincode docker logs I see that a transaction is successfully completed (the asset is added). However the bizNetworkConnection.submitTransaction(resource) doesn't return anything (no error nor a success code).. Is this the normal behaviour or is their something wrong in my transaction definition or client nodejs code? 08:37:59.763 [shim] DEBU : [22a7f079]Transaction completed.

georgeormrod@gmail.com (Wed, 05 Apr 2017 09:03:14 GMT):
Was there a reason behind splitting the full type name when creating a resource instance to import into a registry? for example ``` const factory = businessNetworkDefinition.getFactory(); const asset = factory.newInstance("biz.network", "TestAsset", "id:1"); ``` Whereas, when you get the registry, your using the full name: `getAssetRegistry("biz.network.TestAsset");` I feel it makes it harder to work with when your passing those values in as variables.

gauthampamu (Wed, 05 Apr 2017 09:04:35 GMT):
@dselman Also I did find the supported platforms under references. It does state that it supports Mac 10.12

gauthampamu (Wed, 05 Apr 2017 09:06:45 GMT):
@dselman I have installed fabric composer playground using the alternate install option. Used npm to install it. It starts up fine but how do I setup the connection profile so that I could connect to the local or remote fabric environment. It is not providing an option to update the connection profile in the browser. It says in the documentation that "The playground can then be configured to connect to your existing Hyperledger Fabric instance by creating a connection profile with the required connection settings."

gauthampamu (Wed, 05 Apr 2017 09:30:14 GMT):
Code generation tool is failing with this error. It is looking for the connection profile in /home/composer folder. I am using Mac. On my Mac obviously I don't have this folder and my home directory is different. I have connection profile in my home directory under /Users.

dselman (Wed, 05 Apr 2017 10:44:28 GMT):
@gauthampamu I suspect the `/home/composer/.composer-credentials` path is in the `hlfabric` connection profile itself. How did you create this?

dselman (Wed, 05 Apr 2017 10:45:12 GMT):
You should edit the `hlfabric/connection.json` file to use a path under your home directory.

dselman (Wed, 05 Apr 2017 10:46:13 GMT):
@gauthampamu Composer Playground does not yet support creating connection profiles -- you can either wait for us to finish the UI work, or use the old Composer-UI

dselman (Wed, 05 Apr 2017 10:47:23 GMT):
@bonen this is normal. You have to listen to Fabric events to know the status of transaction processing (this is changing in HLF v1).

dselman (Wed, 05 Apr 2017 10:48:00 GMT):
@uber.twin to remove docker images I use https://coderwall.com/p/ewk0mq/stop-remove-all-docker-containers

Hello, I've recently set up composer-cli and composer-rest-server to run with hlfv1.0. I noticed that in the connection profile there is the possibility to specify more than one peer. I was wondering what that means (both for the deploy and invoke scenario) and if support for multiple peers is also being enabled for v0.6. I assume the deployment will target all the specified peers?

gauthampamu (Wed, 05 Apr 2017 14:42:12 GMT):
Can we have connection profiles other than the /.composer-connection-profile directory ?

dselman (Wed, 05 Apr 2017 14:49:47 GMT):
they can also be loaded from an environment variable. See https://github.com/fabric-composer/fabric-composer/issues/602

Suma (Wed, 05 Apr 2017 15:56:11 GMT):
I believe composer was demoed with hyp v1 at Interconnect? Is there material / videos on that implementation that highlights the changes?

sstone1 (Wed, 05 Apr 2017 16:17:17 GMT):
@elisabetta multiple peers are for high availability - if you specify more than one, the Fabric client will hopefully failover if one falls over

sstone1 (Wed, 05 Apr 2017 16:17:55 GMT):
We don't plan on making any new functional changes to the v0.6 support code so no, we won't be adding multiple peer support for v0.6.

dselman (Wed, 05 Apr 2017 17:09:40 GMT):
If you are running v0.6 you can follow the quick start, and then edit your defaultProfile connection profile to point it at your existing nodes.

Hi guys, one thing I've noticed with our tests (unless my test is wrong) is that upon create a resource with a relationship to another resource that doesn't exist it doesn't error, is that intentional?

Yes, it is intentional.

Hi guys. I want to know how to call "findAnimalsByOwnerId" of "animaltracking-network" with Playground. I want to try "@query"

@tarima bad news... it's not implemented yet. The story is here: https://github.com/fabric-composer/fabric-composer/issues/67

dselman (Wed, 05 Apr 2017 17:14:42 GMT):
We have that planned for Playback 7: https://github.com/fabric-composer/fabric-composer/projects

dselman (Wed, 05 Apr 2017 17:15:13 GMT):
The plan is to map those queries to CouchDB, which required HLF v1.

georgeormrod@gmail.com (Wed, 05 Apr 2017 17:15:59 GMT):
@dselman ok thanks, is referential integrity going to be a feature in the future?

tarima (Wed, 05 Apr 2017 17:16:50 GMT):
@dselman so. "@query" support HL v1 without HL v0.6 right?

dselman (Wed, 05 Apr 2017 17:17:10 GMT):
@georgeormrod@gmail.com I don't think so. It has a pretty high performance cost and is not really compatible with an eventually consistent NoSQL JSON store type approach.

dselman (Wed, 05 Apr 2017 17:17:34 GMT):
@tarima correct -- we can't implement complex queries based on v0.6

tarima (Wed, 05 Apr 2017 17:18:10 GMT):
Thank you. I am always grateful for your help

jdockter (Wed, 05 Apr 2017 18:05:27 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=jYSkXMLaXCtngkPk4) @dselman is your statement just scoped for a create asset, via REST API or Client API? What about when I run a transaction that would create an asset? Can you expand on when a Relationship, ie --> actually enforces that a specific value is found in another asset.

dselman (Wed, 05 Apr 2017 18:12:04 GMT):
When a transaction is submitted to the runtime, the runtime resolves relationships prior to calling the tx processor functions. If a relationship fails to resolve then the runtime fails the transaction.

dselman (Wed, 05 Apr 2017 18:12:46 GMT):
We implemented this so that TX processor functions do not (generally) need to manually resolve relationships.

dselman (Wed, 05 Apr 2017 18:14:31 GMT):
In addition the `resolve` and `resolveAll` methods on Registry attempt to resolve relationships: https://fabric-composer.github.io/jsdoc/module-composer-client.Registry.html#resolve__anchor

dselman (Wed, 05 Apr 2017 18:16:05 GMT):
These are the only cases I'm aware of where relationships are resolved.

jdockter (Wed, 05 Apr 2017 18:27:15 GMT):
@dselman so do you plan to keep that functionality in the core transaction logic of Composer or will that eventually be removed for applications to do on their own transactions using resolve and resolveAll ?

dselman (Wed, 05 Apr 2017 18:28:12 GMT):
I think we will probably keep it. Most tx processors need access to the results of resolution.

dselman (Wed, 05 Apr 2017 18:28:57 GMT):
Maybe we can add a meta-annotation on a tx processor to disable it?

dselman (Wed, 05 Apr 2017 18:29:09 GMT):
We will let the community drive the requirements! ;-)

Folks, for acl. Let's say, I have a participant of a type call Doctor. I am guessing a specific certificate will be issued for an instance of a Doctor (say Dr House). The local version of composer gets a self signed cert. But how will it work with CA? Also a person can have multiple role: a Medical Doctor, a CEO of a hospital, etc). Does it mean a real person who has to sign in in different roles will have to have certs representing different roles?

@duncanjw we are discussing dropping the Fabric and just calling it Hyperledger Composer; as you suggest, we could target the other Hyperledger projects (Sawtooth Lake, Iroha) and the Composer code already has a pluggable adapter layer that allows for this.

sstone1 (Thu, 06 Apr 2017 10:57:40 GMT):
@paul.sitoh participants are issued with identities. identities are enrollment certificates (with a corresponding enrollment ID). a participant can have multiple identities. the composer API/CLIs for issuing identities to a participant will send a register request to the CA to create a new enrollment ID/secret pair.

duncanjw (Thu, 06 Apr 2017 10:58:01 GMT):

On the multiple roles front; you can model the roles as extensions to the base Doctor participant type; e.g. `participant ChiefOfMedicine extends Doctor`. You can also add properties to those participant types and use those in the condition for an ACL rule; for example `o String[] roles`.

What is the relationship between enrollment id and secrets from a composer perspective

sstone1 (Thu, 06 Apr 2017 11:04:32 GMT):
I wouldn't want to include "chain" or "blockchain" in the name as I get the feeling the trend is going to be to move away from "blockchain" towards "DLT" instead. Hyperledger is an umbrella of blockchain/DLT projects so I think that bit is implied.

sstone1 (Thu, 06 Apr 2017 11:04:53 GMT):
Happy to discuss how Cello & Composer might work together.

sstone1 (Thu, 06 Apr 2017 11:05:52 GMT):
Enrollment ID/secret are the credentials that are generated by the CA, which you use to request enrollment certificates from that CA.

paul.sitoh (Thu, 06 Apr 2017 11:06:06 GMT):
Does composer provide a abstraction on top of fabric's credentials?

sstone1 (Thu, 06 Apr 2017 11:06:33 GMT):
Once you enroll, the enrollment secret is no longer valid or required (although our APIs/CLIs don't reflect that).

sstone1 (Thu, 06 Apr 2017 11:07:03 GMT):
Yes, we have an abstraction of participant & identities (where identities are equivalent to Fabric enrollment certificates).

paul.sitoh (Thu, 06 Apr 2017 11:09:38 GMT):
So if a Dr looses the role of Chief of Medicine, and becomes something else, how do we we stop the Dr signing in as Chief of Medicine?

paul.sitoh (Thu, 06 Apr 2017 11:09:52 GMT):
Since roles are tied to cert

paul.sitoh (Thu, 06 Apr 2017 11:10:52 GMT):
It means as long as he has the cert he can signed in as chief of medicine regardless

sstone1 (Thu, 06 Apr 2017 11:10:57 GMT):
No, roles and permissions are tied to the participant.

sstone1 (Thu, 06 Apr 2017 11:11:07 GMT):
The identity (cert) is mapped to a participant.

paul.sitoh (Thu, 06 Apr 2017 11:11:22 GMT):
An instance of a participant?

sstone1 (Thu, 06 Apr 2017 11:11:41 GMT):
Users sign in using the identity. When they make requests to the business network, we look up which instance of a participant that identity maps to.

sstone1 (Thu, 06 Apr 2017 11:11:54 GMT):
ACLs are then based on the participant instance, not the identity (cert).

sstone1 (Thu, 06 Apr 2017 11:12:35 GMT):
So someone (an admin) can change the participant instance to reflect the change in roles and the ACL will pick up on those changes (assuming correctly coded ACL rules) - without having to change/revoke the identity (cert).

paul.sitoh (Thu, 06 Apr 2017 11:13:26 GMT):
But at the fabric level (not composer level) access are govern by cert. So if a person has the cert he can login regardless to Fabric and see data?

paul.sitoh (Thu, 06 Apr 2017 11:13:26 GMT):
But at the fabric level (not composer level) access are govern by cert. So if a person has the cert he can login regardless (of Composer's definition of participant) to Fabric and see data?

dselman (Thu, 06 Apr 2017 11:14:38 GMT):
access to data is governed by chaincode... And the Composer chaincode will enforce the ACL.

sstone1 (Thu, 06 Apr 2017 11:14:40 GMT):
He can only see data if the ACL rules permit.

sstone1 (Thu, 06 Apr 2017 11:14:46 GMT):
^ yes

sstone1 (Thu, 06 Apr 2017 11:15:07 GMT):
The cert could be revoked... in v0.6 we couldn't revoke certs, but I think this is available or coming in v1.0.

sstone1 (Thu, 06 Apr 2017 11:15:32 GMT):
We can only (currently) break the link between identity (cert) and participant and stop people logging in at the chaincode level.

paul.sitoh (Thu, 06 Apr 2017 11:17:41 GMT):
So if I, as a smart user, used HFC or Fabric SDK and not composer, use my cert, and still access blocks where composer (restrict under a specific role), I can still see data that under composer definition is open only to a particular role?

paul.sitoh (Thu, 06 Apr 2017 11:17:59 GMT):
Is my painting of scenario correct at least for v0.6?

paul.sitoh (Thu, 06 Apr 2017 11:18:57 GMT):
Assuming that cert has not been revoked by v0.6 certificate authority?

paul.sitoh (Thu, 06 Apr 2017 11:21:58 GMT):
As far as I understand composer, you will be issue a cert and stored in .composer-credentials and anyone can pinch it and use it to access fabric, at least v0.6

paul.sitoh (Thu, 06 Apr 2017 11:22:12 GMT):
Is that right?

sstone1 (Thu, 06 Apr 2017 11:27:10 GMT):
Yes, if you get hold of someones existing Fabric cert you can then use that cert to access Fabric.

paul.sitoh (Thu, 06 Apr 2017 11:27:32 GMT):
ok thanks for clearing up.

sstone1 (Thu, 06 Apr 2017 11:28:28 GMT):
The only thing we can stop at v0.6 is you calling the Composer chaincode to perform a query or invoke, by rejecting the request because your identity has been revoked.

sstone1 (Thu, 06 Apr 2017 11:28:48 GMT):
We cannot stop you accessing Fabric or actually making the call to the Composer chaincode.

tixu (Thu, 06 Apr 2017 11:34:36 GMT):
hello, I m currently using fabric-composer with the loopbackinterface. I was wondering is there a way to convert error to http code in the business logic. I use the following code `throw new Error("error message") in the transaction code of the network. Can you help me ?

yury (Thu, 06 Apr 2017 11:39:22 GMT):
Has joined the channel.

sstone1 (Thu, 06 Apr 2017 11:46:05 GMT):
@tixu I'm afraid not. With Fabric v0.6 there is no way for us to pass errors back from the chaincode to the client, which is why you only ever see the "transaction timed out" error message.

tixu (Thu, 06 Apr 2017 11:46:35 GMT):
Hope this will be fixe with fabric 1.0.

sstone1 (Thu, 06 Apr 2017 11:46:40 GMT):
With Fabric v1.0 we can pass errors back from the chaincode, but we have not yet considered allowing you to pass back HTTP status codes as well.

tixu (Thu, 06 Apr 2017 11:48:11 GMT):
@sstone1 Fine, I will give a try as soon as it's available, it's a must have for the business.

anyone ever dealt with this error before when attempting to create an asset from within a transaction? `TypeError: 'getFullyQualifiedIdentifier' is not a function`

dselman (Thu, 06 Apr 2017 12:46:59 GMT):
can you post the code that is creating the asset?

pospi (Thu, 06 Apr 2017 13:46:57 GMT):
it's cool, went away now. Was probably something dumb I did

pospi (Thu, 06 Apr 2017 13:53:19 GMT):
but on a somewhat related note, I don't think model inheritance (as we intended to use it) is yet possible. Consider the following two schemas: ``` namespace mydomain.network.core abstract asset BaseAsset identified by id { o String id o DateTime createdOn --> BaseMember invoker --> BaseAsset parent optional } abstract participant BaseMember identified by id { o String id o DateTime createdOn --> BaseMember invoker } abstract transaction BaseTransaction identified by id { o String id o DateTime createdOn --> BaseMember invoker } ``` and (in a parent module) ``` namespace mydomain.network.test import mydomain.network.core.BaseAsset import mydomain.network.core.BaseMember import mydomain.network.core.BaseTransaction asset TestAsset extends BaseAsset { o String testField } participant TestMember extends BaseMember { o String testField } transaction TestTransaction extends BaseTransaction { o String testField } ```

pospi (Thu, 06 Apr 2017 13:53:42 GMT):
yields this error when trying to invoke a transaction: ``` 13:47:26.920 [chaincode] func1 -> DEBU 82b [6e3956f8]No state associated with key: 14$sysregistries46Participant:mydomain.network.core.BaseMember.

Quick feedback on getting started (https://fabric-composer.github.io/tutorials/getting-started-cmd-line.html) . First of all, VERY good. Second, a bit of an explanation on the network vs the application side and possibly showing what directory commands are running from (ie: "back to getting started" meant changing from network to application and navigating out). And when I finished and it all went well, I saw the 3 follow-on links which all look like they will be great but ... all are broken links. I think I'll be able to navigate thru the rough info via the nav bar on the left ... but maybe a ref to doing that vs trying to keep these links up to date would be a good idea. Thanks PS. This may get obvious as I move on, but my theory at this point is that the javaScript is part of the "chainCode" and that I'll be able to generate REST calls to drive it ... and that there is some code generated from the model (go code?) that is the final interface to the hyperledger (RocksDB on 0.6 and I guess some couch DB in 1.0)?

dselman (Thu, 06 Apr 2017 17:26:42 GMT):
@MikeC711 thanks for the feedback. @EdProsser is working on fixing those links. Yes, you can generate REST APIs for a business network using the composer-rest-server (based on the Loopback framework). No, Composer doesn't generate any Go code -- the JS code is interpreted using generic chaincode (written in Go) that interfaces to the underlying Fabric APIs.

Unrelated to the previous issue, since upgrading to docker-composer v1.8 I wanted to see if the installation method used previously was effected. It was not and now the four-peer.yaml files launches as well too. However since that reference document was last updated there have been changes made to login as a peer. This login is referenced: peer network login test_user0 -p MS9qrN8hFjlE Whereas this is what is the user hardcoded in to the membersrvc.yaml:

@dselman I pulled down the latest version of composer and export is working fine. Thank you!!

GoodFaith (Sun, 09 Apr 2017 15:39:37 GMT):
@olazzizz The Docker-Compose dependency is listed as v1.8+. You need to update Docker-Compose. Once the 'node cli.js landregistry bootstrap' issue is addressed the package should load as stated, as of now it seems as if it is busted.

olazzizz (Sun, 09 Apr 2017 17:10:00 GMT):
@GoodFaith In my environment the version of docker-compose was 1.10.0. Anyway I followed your suggestion and I uninstalled that version and installed docker-compose v1.8.1. The result doesn't change though, I get the very same error after running npm install.

GoodFaith (Sun, 09 Apr 2017 17:14:20 GMT):
@olazzizz I knew you would. I'm wanting to set up the business network myself and had the same error you did. It has something to do with the node cli.js landregistry bootstrap. Based on the dependencies listed in the installation guide you'll need that version of docker-compose once the issue is resolved though.

GoodFaith (Sun, 09 Apr 2017 17:40:26 GMT):
The connections profile will be where you initially downloaded the file to.

GoodFaith (Sun, 09 Apr 2017 17:43:37 GMT):
Or I could be wrong....here's further information listed for fabric-composer connection profiles. https://fabric-composer.github.io/reference/connectionprofile.html

dselman (Sun, 09 Apr 2017 19:07:30 GMT):
@vishwass you should not need to run the tests to use Composer. If you are wanting to modify Composer itself, please use the #composer-dev channel.

dselman (Sun, 09 Apr 2017 19:07:47 GMT):
(the issue is that you have not run `lerna bootstrap`).

dselman (Sun, 09 Apr 2017 19:10:25 GMT):
@GoodFaith @olazzizz I'm having following the questions/issues. Could you please post a question to StackOverflow using the #fabric-composer tag. This issue is usually due to a prior install issue (often installing composer-cli). Can you check that installed cleanly? What do you get if you type `composer --version`?

@tennenjl that may be related to the issue I am working on creating business network archives. I'll keep you posted.

@dselman Much obliged, appreciate the help.

tennenjl (Sun, 09 Apr 2017 21:52:32 GMT):
Sorry for the noob question, but if I'm reading through this channel correctly, if I want to deploy to Bluemix Dev (Hyperledger fabric v.6), I will need to install composer-ui versus composer-playground. Is this correct? Thanks!

dselman (Sun, 09 Apr 2017 22:32:21 GMT):
Yes, that is correct. We are working on adding connection profile support to composer-ui at the moment.

tennenjl (Mon, 10 Apr 2017 01:44:22 GMT):
Hi, I'm sure I'm doing something silly but when I try switching connection profiles using the composer-ui running locally to point to Bluemix, it appears to hang. The screen displays "Establishing admin connection..." and the chrome dev tools console shows "Connecting to connection profile (w/ business network ID) and the name I provided for my profile "car_lease_blockchain_jtenn". I'm happy to share my settings. I also am doing my best to follow the suggestions provided here: http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service . Thanks for any debugging suggestions!

I have question related to composer query. Suppose I defined a Model like:

ibmamnt (Mon, 10 Apr 2017 06:27:44 GMT):
```asset VehicleListing identified by listingId { o String listingId o Double reservePrice o String description o ListingState state o Offer[] offers optional --> Vehicle vehicle }```

ibmamnt (Mon, 10 Apr 2017 06:27:58 GMT):
asset VehicleListing identified by listingId { o String listingId o Double reservePrice o String description o ListingState state o Offer[] offers optional --> Vehicle vehicle }`

ibmamnt (Mon, 10 Apr 2017 06:28:17 GMT):
And there are 30,000 instances of this model. If we query without listingid, does composer return 30,000 instances ? And is there any way to specify where like statement (e.g. where state = ‘SOLD’) ? (As far as I know about KVS range query, this is not possible, but I just thought fabric may have world around this limitation already). Thanks!

@daragao Can you provide some details regarding the problems you are seeing?

Jakeeyturner (Mon, 10 Apr 2017 14:59:41 GMT):
Hi @daragao, we've noticed that something went wrong with our latest code build. This is causing the quickstart to fail (and a few other things). We're hoping to have our fix implemented within the next hour or so

daragao (Mon, 10 Apr 2017 14:59:48 GMT):
when doing `npm install` I get: ``` npm ERR!

daragao (Mon, 10 Apr 2017 15:03:22 GMT):
;)

daragao (Mon, 10 Apr 2017 15:03:29 GMT):

Jakeeyturner (Mon, 10 Apr 2017 15:03:31 GMT):
but you'll need to change a few things in the sample-applications possibly

Jakeeyturner (Mon, 10 Apr 2017 15:03:55 GMT):
If you can hold on an hour or so, then there shouldn't be any hacking!

There's an issue here: https://github.com/fabric-composer/fabric-composer/issues/57 although I'm not sure what the method for doing this is. Sorry, I haven't done much in regards to ACL's

daragao (Mon, 10 Apr 2017 15:09:29 GMT):
a very basic and silly question, but the Fabric Composer is only a sandbox to build applications for the Fabric Blockchain? or anything more? Where can I check a good tutorial on how to deploy and Fabric Blockchain locally? And create contracts on it?

Jakeeyturner (Mon, 10 Apr 2017 15:10:21 GMT):
we've got some solid docs here (constantly being improved) - https://fabric-composer.github.io/

daragao (Mon, 10 Apr 2017 15:12:56 GMT):
still a bit confused, about what is what (I am used to Ethereum, but new to Fabric) well guess that I have to read more

Jakeeyturner (Mon, 10 Apr 2017 15:15:34 GMT):
Not a problem, Fabric Composer basically allows you to model a business network and create an application quickly and more easily than traditional methods. There are numerous tools which will help throughout that process. It's worth taking a look through here: https://fabric-composer.github.io/introduction/introduction.html and if you have any questions definitely feel free to ask!

daragao (Mon, 10 Apr 2017 15:18:20 GMT):
that's what I have been following, and it seems pretty cool and clear

daragao (Mon, 10 Apr 2017 15:19:12 GMT):
my main doubt is how do I actually launch a bunch of nodes locally, I have tried the basics of fabric composer and it seems cool, just want to do it for real

daragao (Mon, 10 Apr 2017 15:19:13 GMT):
:)

daragao (Mon, 10 Apr 2017 15:19:52 GMT):
but lost about which tutorial to follow in order to deploy and bunch of nodes, and add a some chaincode to them

Jakeeyturner (Mon, 10 Apr 2017 15:21:50 GMT):
You'll probably want to have a look here then: https://fabric-composer.github.io/tutorials/getting-started-cmd-line.html

daragao (Mon, 10 Apr 2017 15:31:42 GMT):
so fabric composer actually deploys a network of nodes?

daragao (Mon, 10 Apr 2017 15:32:00 GMT):
ok, better read this, before making more questions hahaha

Jakeeyturner (Mon, 10 Apr 2017 15:36:28 GMT):
You'd deploy what you've modeled to the nodes

daragao (Mon, 10 Apr 2017 15:40:24 GMT):
pity to start this I need to have run quickstart :S which depends on the composer

daragao (Mon, 10 Apr 2017 15:40:35 GMT):
anyway, I'll read it now, and try it later

Jakeeyturner (Mon, 10 Apr 2017 15:42:14 GMT):
yeah, sorry about that. Currently getting one more change in before a new build is released, that should fix the quickstart for you :) There will be an announcement once a new build is made

daragao (Mon, 10 Apr 2017 15:43:24 GMT):
cool thanks again @Jakeeyturner

@tennenjl if you have cut and pasted the certificate info into the composer-ui panel, then I would suggest taking out all the \n entries.

@davidkel Thank you, I'll give that a shot.

annbnn (Mon, 10 Apr 2017 16:11:20 GMT):
@Jakeeyturner For demo purpose, is it possile to create Connection Profiles located in different countries in order to use them on the playground composer ?

annbnn (Mon, 10 Apr 2017 16:11:59 GMT):
Let say 3 participants located in canada, us and france as member in an application.

annbnn (Mon, 10 Apr 2017 16:12:29 GMT):
Using url or ip addresses.

Jakeeyturner (Mon, 10 Apr 2017 16:12:42 GMT):
A connection profile just points at the running Hyperledger Fabric. So, a user can share this connection profile

@here *Release notes for Fabric Composer v0.5.10* :tada::tada: Hey everyone, we are about to cut a release for the latest version of Fabric Composer, expect the Docs/Website/Playground to be down for a short period. What has changed: - Rollback breaking changes to composer-common (from v0.5.9). - Link fixes in documentation (mainly in the tutorials). - Graceful fallback for iOS devices and Safari browsers on the main website homepage. _(for more info please see https://github.com/fabric-composer/fabric-composer/releases)_ Any problems let us know! :tada::tada::tada::tada:

daragao (Mon, 10 Apr 2017 16:37:33 GMT):
when will it be available on npm?

annbnn (Mon, 10 Apr 2017 16:41:48 GMT):
Hi All. Is there a paper about comparing Ehtereum and Hyperledger Fabric ?

annbnn (Mon, 10 Apr 2017 16:42:15 GMT):
What would be the best way to do a demo using Hyperledger Fabric for people who already know Ethereum ?

annbnn (Mon, 10 Apr 2017 16:42:21 GMT):
Thank you for your advices

daragao (Mon, 10 Apr 2017 16:43:20 GMT):
@annbnn would love also to check something like that

tennenjl (Mon, 10 Apr 2017 16:45:34 GMT):
@annbnn I would ask on the fabric-questions channel. There was an altoros video on the topic, but that was a while back. Things to consider are the approach to consensus, language support for chaincode, etc

daragao (Mon, 10 Apr 2017 16:49:47 GMT):
sorry for being so annoying but: https://www.npmjs.com/package/composer-cli is still with the 0.5.9 version :(

jtonline (Mon, 10 Apr 2017 16:56:41 GMT):
@daragao I think it could be a couple of hours based on previous builds (unless I'm looking at the wrong thing in travis)

daragao (Mon, 10 Apr 2017 16:58:29 GMT):
;) ok thanks

jtonline (Mon, 10 Apr 2017 17:51:32 GMT):
@daragao it looks like it's 0.5.10 now, although there were build errors deploying composer-playground

jtonline (Mon, 10 Apr 2017 18:23:00 GMT):
Apologies for the vanishing composer playground- the build is rerunning at the moment

@kpsid installing locally should work, or you could try https://composer-playground-unstable.mybluemix.net/

@daragao I'm not sure what's causing your npm install woes- I've just tried the quickstart in this vagrant environment and it all seemed to work -> https://github.com/jthub/composer-quickstart-vagrant

daragao (Mon, 10 Apr 2017 19:02:57 GMT):

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=RLDzdJh8XMW8Xqh4j) @tennenjl just catching up - I'm not sure what my schedule is yet, have you considered coming along to the Hackfest? It's free and I'm very happy to help people get up and running with Composer as well as hacking on the Composer source :)

davidkel (Mon, 10 Apr 2017 20:20:44 GMT):
@tennenjl that looks like there is some problem enrolling your user and creating the ecert

sstone1 (Mon, 10 Apr 2017 20:21:01 GMT):
Your identity or token does not match error suggests that someone has already enrolled as user_type1_0 or the enrollment secret has changed (if you've recreated the service)

tennenjl (Mon, 10 Apr 2017 20:21:26 GMT):
@sstone1, yes, still hoping to make it out to the hackfest, need to register I suppose :D

another dummy question.. Once you have deployed chain code (in this case the chaincode is in stopped) status. Is it possible to deploy new code via the composer. (Using the old composer-ui for now), or do I need to delete and create a new service. Thanks!

Updated composer-cli to v0.5.10, but when doing npm install I get error: git submodule init && git submodule update && lerna bootstrap fatal: Not a git repository (or any of the parent directories): .git. Previously install would spin up an instance of membrserv and one peer node?

davidkel (Mon, 10 Apr 2017 22:29:14 GMT):
@GoodFaith what directory were you in when you ran npm install ? It looks like you have a package.json file from the root of the fabric composer source tree

GoodFaith (Mon, 10 Apr 2017 22:51:56 GMT):
I just changed the name of the folder to shorten it.

GoodFaith (Mon, 10 Apr 2017 22:55:42 GMT):
Better yet, which directory should we run it from?

davidkel (Mon, 10 Apr 2017 22:55:50 GMT):
@GoodFaith where you trying to use the getting started package in the sample applications ?

davidkel (Mon, 10 Apr 2017 22:55:50 GMT):
@GoodFaith were you trying to use the getting started package in the sample applications ?

GoodFaith (Mon, 10 Apr 2017 22:56:00 GMT):
Yes.

davidkel (Mon, 10 Apr 2017 22:58:34 GMT):
@GoodFaith so running npm install in that directory is correct, what is confusing is the contents of package.json in that folder are wrong. It might be worth getting rid of the directory and re-cloning the sample applications git repository

GoodFaith (Mon, 10 Apr 2017 22:58:49 GMT):
I pulled down the new the folder that was posted today. https://codeload.github.com/fabric-composer/fabric-composer/zip/v0.5.10 It has the packages folder, but not the getting started.

davidkel (Mon, 10 Apr 2017 22:59:58 GMT):
@GoodFaith that is a zip of the complete source tree of fabric-composer which I don't think is what you want

davidkel (Mon, 10 Apr 2017 22:59:58 GMT):
@GoodFaith that is a zip of the complete source tree of fabric-composer which I don't think is what you want. composer-cli v0.5.10 has been published to npm, so you can use npm to install/upgrade the latest version of composer-cli

GoodFaith (Mon, 10 Apr 2017 23:09:07 GMT):
I've updated composer-cli, it's installed. I'll install sample applications again see if I have any errors. When updating the composer-cli I get WARN depreciated messages like: npm WARN deprecated node-uuid@1.4.8: Use uuid module instead npm WARN deprecated jade@1.11.0: Jade has been renamed to pug, please install the latest version of pug instead of jade npm WARN deprecated transformers@2.1.0: Deprecated, use jstransformer When I run composer --version is returns: composer-cli v0.5.10 composer-admin v0.5.10 composer-client v0.5.10 composer-common v0.5.10 composer-runtime-hlf v0.5.10 composer-connector-hlf v0.5.10 Is that installing correctly?

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=wqdBtf4pw3rS3aNp2) @PraveenU this error means that your ECerts are not valid (usually because you have restarted the Fabric after an enroll). You can simply delete the ~/.composer-credentials folder and rerun.

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=zjoX3fxzgAXb2xYbH) @saridsa1 did you deploy the BNA file with the id `com.n.iandd` using the `defaultProfile` connection profile. You need to deploy the BNA and have it running to use this generator option. Alternatively give the generator the path to the BNA file and it will generate based on that.

@daragao can you try `rm -rf ./node_modules` followed by `npm uninstall -g composer-cli` followed by `npm install -g composer-cli`

dselman (Tue, 11 Apr 2017 08:32:54 GMT):
that should ensure you are updated to v0.5.10

Hi @winslet and all of you (I applied there yesterday hahahaha) will do @dselman for now it seems to beat Ethereum on those terms, at least when I was starting out with Ethereum a few months ago (~8 months), it is just confusing, all the different repos you have but will try and make a clearer opinion later :D

annbnn (Tue, 11 Apr 2017 11:27:01 GMT):
@dselman What would be the best strategy to check that ACL rules (defined for the assets in permissions.acl) work during unit tests ?

annbnn (Tue, 11 Apr 2017 11:27:58 GMT):
@dselman Also how would the best way to present the hyperledger for people who already know Ethereum ?

gauthampamu (Tue, 11 Apr 2017 11:33:22 GMT):
I have a question on participants in the composer. We have API to add participants to the network and I have seen in some samples we add those participants using the API using the connection profile of an Admin. When you are forming the network for real use case and especially in v1.0 and also I have seen in the HSBN service, you have to invite participants to the network and they can join and it automatically creates the peers for those participants. How do you map those participants to the participants in composer model. Are you still expected to create the participants in the ledger using the composer SDK. In v1.0 and even 0.6, when you add a participants, it provides an enrollment id. How do you map that with the participant information that you create in the ledger using the composer API to the enrolled participants in the ledger. Also when you add the participants in the ledger, is it really registering the participants ?

dselman (Tue, 11 Apr 2017 11:33:49 GMT):
@annbnn so @sstone1 has been working on embedded mode support for ACL enforcement, this will allow you to write a Node.js unit test (running agains the Composer embedded runtime) and check that ACLs are correct. @sstone1 is that ready for prime time? Alternatively you can run your unit tests against a real HLF -- that is what we do in our system tests.

dselman (Tue, 11 Apr 2017 11:34:31 GMT):
@annbnn I think we should work on a compare/contrast infographic. AFAIK we don't have that yet, but it is a very good idea.

dselman (Tue, 11 Apr 2017 11:35:31 GMT):
@gauthampamu can you please post this to StackOverflow -- the answer will be fairly long and we want others to be able to find it.

annbnn (Tue, 11 Apr 2017 11:45:01 GMT):
@dselman What do you mean by *you can run unit tests against a real HLF* ?

dselman (Tue, 11 Apr 2017 11:49:14 GMT):
@annbnn here is the unit test for the Car-Auction sample network: https://github.com/fabric-composer/sample-networks/blob/master/packages/carauction-network/test/CarAuction.js

dselman (Tue, 11 Apr 2017 11:49:23 GMT):
It runs an auction and checks the results.

dselman (Tue, 11 Apr 2017 11:50:33 GMT):
If you remove the call to `createProfile` is will use the `defaultProfile` to run the auction. If this is to a real HLF instance then the test will run against it, and the runtime will enforce ACL checks.

dselman (Tue, 11 Apr 2017 11:51:01 GMT):
You should definitely create a unit test for all your business logic...

annbnn (Tue, 11 Apr 2017 11:53:26 GMT):
I understand. I will check with the Car-Auction

annbnn (Tue, 11 Apr 2017 11:53:27 GMT):
Thank you

annbnn (Tue, 11 Apr 2017 12:09:00 GMT):
@dselman To run the unit test on CarAuction.js, I should do what its done her ? : https://fabric-composer.github.io/tutorials/getting-started-cmd-line.html

annbnn (Tue, 11 Apr 2017 12:09:02 GMT):
Right ?

annbnn (Tue, 11 Apr 2017 12:09:09 GMT):
Or there is something else to do ?

dselman (Tue, 11 Apr 2017 12:10:01 GMT):
`git clone https://github.com/fabric-composer/sample-networks.git`

dselman (Tue, 11 Apr 2017 12:10:37 GMT):
then `cd sample-networks/packages/carauction-network/`

`npm install`

dselman (Tue, 11 Apr 2017 12:10:48 GMT):
`npm test`

annbnn (Tue, 11 Apr 2017 12:12:23 GMT):
I use the same strategy with the the unit test file related to my application

annbnn (Tue, 11 Apr 2017 12:12:25 GMT):
right ?

sstone1 (Tue, 11 Apr 2017 12:18:22 GMT):
The Composer embedded runtime fully supports identities & ACLs now, so you should be able to write any required unit tests using Mocha and the Composer APIs. I don't think there's a good example of this though.

annbnn (Tue, 11 Apr 2017 12:19:23 GMT):

jdockter (Tue, 11 Apr 2017 13:44:48 GMT):
@sstone1 probably asked this question in the past for v0.6 and maybe it won't be different in v1.0, but can't remember what was said...as Composer moves to supporting HLF v1.0 and CouchDB, want to make sure I have the right visual perspective of this document database. When we go to create Assets, Participants, Transactions and Identities, those are called out as being part of registries. Will CouchDB represent all of those in one table or is there more of a schema.table configuration where each registry will be separated out?

sstone1 (Tue, 11 Apr 2017 14:15:25 GMT):
We have no control over where CouchDB puts data, at least last time I checked. There will be a single collection with all of the JSON documents in.

sstone1 (Tue, 11 Apr 2017 14:16:16 GMT):
IIRC the collection is named after the chaincode ID but I might be wrong.

jdockter (Tue, 11 Apr 2017 14:28:12 GMT):

@jdockter @sstone1 I have a question about the documented example on the website. The image attached shows an Asset called 'Vehicle' with a 'Customer' property. This customer property is another Participant as modeled but is not denoted as a '-->' can you explain why this works?

yep!

sbrakev (Tue, 11 Apr 2017 16:15:26 GMT):
A Customer in this case was just a 'Concept' huh?

sstone1 (Tue, 11 Apr 2017 16:16:00 GMT):
Very similar, except the Customer has an ID. But the Customer is stored in the Vehicle asset in the Vehicle registry, not in the Customer registry - unless you explicitly add it.

dselman (Tue, 11 Apr 2017 16:16:14 GMT):
Yes, that should be changed to `-->`

sstone1 (Tue, 11 Apr 2017 16:16:27 GMT):
Should we ban `o AssetType` ?

sstone1 (Tue, 11 Apr 2017 16:16:33 GMT):
What's the use for it now we have concepts?

dselman (Tue, 11 Apr 2017 16:17:04 GMT):
Yes, I think it should be prohibited

sstone1 (Tue, 11 Apr 2017 16:17:20 GMT):
I guess it's easy to create new instances of AssetType via a TransactionType by just passing them in... but it's a bit confusing

dselman (Tue, 11 Apr 2017 16:17:46 GMT):
Agreed. Better to have the asset wrap a "details" concept instead.

jdockter (Tue, 11 Apr 2017 16:48:29 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=ZPH5eY8Y4FJPr8raP) @sbrakev we have gone around around with this in our model. Basically when we want an asset to "own" another structure (for lack of better word) we use concept, thus if we were to delete the asset we would delete the associated concept. When we know the assets/structures are independent, one can be deleted or updated with out touching the other, but related, we use the relationship symbol `-->`, then using Transactions we can resolve the relationship during run time.. @dselman and @sstone1 not sure if best practice but that is direction we have gone for now

No

The composer UI is running as node application and it connected to the fabric v0.6 running in Docker

gauthampamu (Tue, 11 Apr 2017 17:34:54 GMT):
I have successfully deploy the business network definition and it deployed the chaincode. I was able to add participants

After doing some noodling with HLF V1.0 ... I noted I needed a new go (maybe that's my problem?). I had 1.6x and HLF needed at least 1.7x ... I went to go and built 1.8x (which may be my issue). I then went back thru and wanted to do Composer Quickstart to take a small model from soup to nuts (https://fabric-composer.github.io/installing/quickstart.html). It gave some trouble with errors:

MikeC711 (Wed, 12 Apr 2017 02:06:55 GMT):
Woops, sorry about hitting enter there: AttributeError: 'module' object has no attribute 'PROTOCOL_SSLv3' So I went thru and wacked where I had cloned the git repos and started again. Full file is attached (next) ... but I still got the PROTOCOL_SSLv3 error and many after it. Any thoughts? Do I need to go back to go 1.7? Any other possibilities for my malady?

Personally had errors in install with methods shared on the quick-start page. Would recommend following this guide. https://fabric-composer.github.io/tutorials/getting-started-playground.html There's a number of different business network definitions for proof of concepts.

MikeC711 (Wed, 12 Apr 2017 02:23:31 GMT):
Thanks GoodFaith, will look into that ... but may also be tied to pip or some of the other install work I did wrt HLF 1.0. I saw a similar problem an individual had and using pip to update docker-compose fixed it. Looking into that, not happening so far ... but I think you are on the right track wrt preReqs. If I just type docker-compose --version ... I get the same error, so it likely has nothing to do w/Composer and everything to do with environment tied to docker-compose and pip. Will re-attack in the AM. Thanks again.

hi, I am trying to run the "composer-rest-server" with my deployed business network and I get this error "Connection fails: Error: Deployed chain-code (0.4.5) is incompatible with client (0.5.10" could anybody have an advice on this issue?

@uber.twin looks like you are trying to run the composer-rest-server which is version 0.5.10 whereas your deployed business network was done using a 0.4.5 implementation. Because of a version mismatch the rest server cannot communicate with the business network

dselman (Wed, 12 Apr 2017 09:36:02 GMT):
@saridsa1 that generator is supposed to create a skeleton business network. Instead of using the generator you can copy/paste and modify an existing example. E.g. https://github.com/fabric-composer/sample-networks/tree/master/packages/carauction-network

annbnn (Wed, 12 Apr 2017 09:37:50 GMT):
@dselman How to use map the digitalproperty-network (or Carauction for example) hyperledger in a real software application people in different countries could use ?

dselman (Wed, 12 Apr 2017 09:37:52 GMT):
@annbnn the answer is yes. When you run the Quick Start you are running digitalproperty-network against HLF v0.6.

dselman (Wed, 12 Apr 2017 09:39:33 GMT):
I get the impression that you are looking for some sort of end-to-end application/solution blueprint. We don't have that yet. It involves applications calling the REST API exposed by the composer-rest-server, making the composer-rest-server HA, managing digital certificates etc.

dselman (Wed, 12 Apr 2017 09:39:55 GMT):
We have the piece parts but AFAIK no one has yet written up how to pull them all together.

dselman (Wed, 12 Apr 2017 09:40:25 GMT):
If you create a StackOverflow question tagged with fabric-composer we can start to elaborate on an answer there.

annbnn (Wed, 12 Apr 2017 09:41:53 GMT):
@dselman Yes, you are right. Because people are asking me if its possible to create an end-to-end application/solution blueprint using hyperledger.

annbnn (Wed, 12 Apr 2017 09:44:00 GMT):
@dselman Lets back to profile creation question. Do you have an example where you used that technic to make some test ? (playground composer is good to test things locally)

annbnn (Wed, 12 Apr 2017 09:45:17 GMT):
Let take the CarAuction example.

annbnn (Wed, 12 Apr 2017 09:46:00 GMT):
I would like to create two members with 2 IP adresses in a private or public network.

annbnn (Wed, 12 Apr 2017 09:46:16 GMT):
How to proceed for the CarAuction demo ?

annbnn (Wed, 12 Apr 2017 09:46:41 GMT):
What is the strategy to do that ?

dselman (Wed, 12 Apr 2017 10:02:32 GMT):
That's not really a Composer question -- you need to setup a Fabric with 2 peers running on different IP addresses and then create a connection profile for each IP address.

dselman (Wed, 12 Apr 2017 10:03:21 GMT):
So, first step is to get HLF running on a couple of machines.

dselman (Wed, 12 Apr 2017 10:04:11 GMT):
The #fabric channel and docs can help with that. Once your Fabric is up and running across the machines creating the Composer connection profiles will be easy -- you just have to plugin the right IP addresses.

annbnn (Wed, 12 Apr 2017 10:09:51 GMT):
@dselman Well, technically speaking what does mean *HLF* running on two machines ?

annbnn (Wed, 12 Apr 2017 10:09:56 GMT):
Let start with that.

dselman (Wed, 12 Apr 2017 10:10:21 GMT):
HLF == Hyperledger Fabric

annbnn (Wed, 12 Apr 2017 10:13:24 GMT):
Hyperledger Fabric running on a machine is what you explained here ? https://fabric-composer.github.io/applications/getting-started-nodejs-app.html

annbnn (Wed, 12 Apr 2017 10:13:37 GMT):
@dselman

dselman (Wed, 12 Apr 2017 10:15:02 GMT):
I can't help you get HLF running across multiple machines. You should use the #fabric channel for that, and their docs of course.

annbnn (Wed, 12 Apr 2017 10:15:17 GMT):
Okay, I will see that

uber.twin (Wed, 12 Apr 2017 11:36:52 GMT):
@dselman It's not completely clear for me the way relations and agregation are possible between various concepts (Asset, Participant, Transaction) when defining the domain model. Actually I thought only relations are possible between various concept instances, not direct agregation. I am looking at VehicleListing definition and it looks like it's declaring a direct agregation of Offers asset VehicleListing identified by listingId { o String listingId o Double reservePrice o String description o ListingState state o Offer[] offers optional --> Vehicle vehicle }

uber.twin (Wed, 12 Apr 2017 11:39:21 GMT):
so, is it possible that any kind of concept stereotype to aggregate any other concept stereotype?

MikeC711 (Wed, 12 Apr 2017 12:17:56 GMT):
Just an FYI since other slow understudies may run into this as well. If someone tries to use docker-compose to bring up their tutorial/getting-started environment and get: AttributeError: 'module' object has no attribute 'PROTOCOL_SSLv3' (I got this because I had upgraded some software based on looking to play with HLF V1 as well) ... first have them just do docker-compose -v ... and they may run into the same message. Lots of solutions on google, most did not work for me, but 2 things that did work (first I'm not sure, second definitely fixed it): sudo easy_install --upgrade pip sudo pip install requests --upgrade That updated urllib3 which apparently was the real bugger here. So if someone gets that SSLv3 message (and as people go to HLF V1 they may) ... this solution worked for me. The easiest part is that, once someone sees that docker-compose -v doesn't work ... it's obviously no longer a HFC problem

MikeC711 (Wed, 12 Apr 2017 12:25:42 GMT):
PS. You may not even have to be a slow understudy like me to run into that problem

davidkel (Wed, 12 Apr 2017 12:32:50 GMT):
@MikeC711 I don't recommend installing docker-compose via pip, also don't install v1.12, install v1.11. v1.12 won't work with HLF v1 docker compose files

dselman (Wed, 12 Apr 2017 15:07:40 GMT):
@uber.twin I would not aggregate assets or participants -- I would create an array of relationships to them. Arrays of transactions are supported (and fairly common).

OK, first model attempt. I created containers local and am in playground. When I try to create my first Client I hit "Create New Participant" and get error: Error: Instance null:3989 has a property named null which is not declared in org.acme.sample.AddressInfo Relevant model info: concept AddressInfo { o String streetAddr o String city o String state o String zipcode } abstract participant User identified by userID { o String userID o String firstName o String lastName } participant Client extends User { o Integer ssn o AddressInfo address } I'm still pursuing, but if anyone sees the error in my ways, please do speak up. Thanks,

MikeC711 (Wed, 12 Apr 2017 16:35:00 GMT):
One point I did not bring up, playground itself is reporting "Everything looks good"

MikeC711 (Wed, 12 Apr 2017 16:49:14 GMT):
FYI: I found my participant and asset that included a concept failed. So I copied in the fields and commented out the ref to the concept ... and I am now OK. Looking at samples, I think my concept is all good, if it is ... wondering if the playground doesn't handle concepts ... or if there is a larger issue right now.

uber.twin (Wed, 12 Apr 2017 17:49:14 GMT):
@dselman Thank you for the specifics. I got another uncertainty about the limitation regarding how many validating peers can coexist in a fabric environment. Is it accurate that there should not be more than arround 20, otherwise the performance is deteriorating? If so are there any hopes of improvement in this direction? The perspectives are I'll need to accomodate arround 50 such peers.

daragao (Wed, 12 Apr 2017 18:19:47 GMT):
I have a few questions if anyone knows (they are quite basic): - What is the connection profile for, why don't is it needed for the tutorials - How do I create the certificates for the connection profile? - What is the difference between the requestURL and the eventURL? Is it only the input port and and output port? - How can I check how many nodes fabric has deployed with the fabric-composer and their status? - Is there a API documentation about the requests that we can make directly to the fabric nodes (avoiding to use the composer-rest-server NPM)?

dselman (Wed, 12 Apr 2017 18:24:44 GMT):

@uber.twin 50 is a big number -- that amounts to 50 people/orgs that have such a large stake in a network that they want to help run it...

dselman (Wed, 12 Apr 2017 18:30:45 GMT):
@daragao 1/ connection profiles tell Composer how to connect to the blockchain (Fabric). They are used by the tutorials -- however if a default profile is created automatically which assumes you are running Fabric locally. 2/ What certificates are you referring to? ECerts are downloaded automatically from membership services on connection. 3/ requestURL is used to connect to peers. eventURL is used to connect to the event hub, which allows events to be sent back to the client. 4/ `docker ps -a` will show you the running docker containers. 5/ https://fabric-composer.github.io/reference/ see the API Docs.

daragao (Wed, 12 Apr 2017 18:37:13 GMT):
cool @dselman the certificates I meant the ones associate with the connection profile also the tutorials always as for a username and secret, does that have anything to do with the connection profile? how do I create it?

@dargo The membersrvc is the identity management baked into HLF. vp0_1 is a node that performs consensus in the blockchain ecosystem. Not 100% sure what the dev-vp0 node is other than it appears to contain a hashtag, and it appears to be, perhaps, a public key address. Why that node is defined as such I don't really know, but my guess would be it is the node the administrator publishes the business network definition to. Hyperledger isn't like Bitcoin, Ethereum or a number of derivatives of either of them, and quite a bit is changing as far as consensus is concerned with HLF V1.

Hey Dan, No, I am not using the Bluemix playground. I am running the playground locally. If I pick up the latest images ... will that be good ... or is there something more I need?

dselman (Thu, 13 Apr 2017 05:28:55 GMT):
@daragao those are Fabric questions, please check the docs. `membersrvc` is the membership services container, it controls access to the Fabric. `vp0` is a peer node, an entry point into your Fabric. This would be run by an organization that was responsible for the maintenance of the network itself. `dev-vp0-1` is a chaincode container (there will be one per peer, per chaincode) -- this is where your business network definition executes. It runs in its own Docker container so you get isolation.

dselman (Thu, 13 Apr 2017 05:29:50 GMT):
@kouohhashi Fabric support for Node is via the Fabric-Node-SDK. Yes, the latest version of the SDK supports HLF v1.

dselman (Thu, 13 Apr 2017 05:30:12 GMT):
@MikeC711 yes, just update your image and you should be good to go.

@georgeormrod@gmail.com the easiest thing to do is to create a `concept` in your model to hold the _details_ and then you can simply copy that concept from your incoming transaction to the asset you want to create.

dselman (Thu, 13 Apr 2017 10:35:35 GMT):

Thanks Dan, So I repulled the Fabric but I was up to date (docker pull) which found no changes ... I just did a git pull from https://github.com/fabric-composer/sample-applications.git ... then I did a docker pull of fabriccomposer/composer-playground ... I brought it up and it asked me to clear cache and it shows me I'm at 0.0.6 (I think prior was 0.0.5). The good news is that export works where it did not work well for me prior ... but the very bad news is import seems to pop up a screen (too quickly to read) ... then the screen goes away and I never get a chance to browse for bna file and import it. I will go try the bluemix flavor and see if I can do better there. Is there more that I need to do to get the latest? Thanks,

MikeC711 (Thu, 13 Apr 2017 12:49:58 GMT):
FYI: It does work fine on the Bluemix playground, but I would like to have my playground functional ... so if you could show me what I'm doing wrong, I would appreciate it. Thanks,

@dselman Regarding the limitations upon the maximum number of peers establishing the consensus, I need to consider it in the context of an inter-institution settlement solution. It'll be a problem to choose which of all participating institutions will be allowed to have a corresponding peer invested with endorsing privileges, knowing that there can be only ~ 20 elected as such. How would one elect such peers from a pool of equally interested parties?

As mentioned on the community call, if anyone wants to try fabric composer with hyperledger fabric v1 alpha as a replacement to a v0.6 runtime. I have a simple script that will prepare a simple v1 runtime for you. It will - download the alpha docker images - download configuration files to hlfv1 - create running containers for hlfv1 - create a channel called 'mychannel' and join the peers to it - it will create a composer connection profile called hlfv1 it will use a directory called .hfc-key-store in your home directory so you might want to remove this directory first as this is where the ECerts are stored. Once up and running you can use fabric composer as normal with an EnrollId of 'admin' and EnrollSecret of 'adminpw' and the connection profile 'hlfv1' I would recommend being at the latest level of fabric-composer which is currently v0.5.10 The script can be found at ``` https://github.com/davidkel/sandbox/raw/master/hlfv1/SetupV1Alpha.sh ``` or if you want you can just execute it without storing it by issuing ``` curl -L https://github.com/davidkel/sandbox/raw/master/hlfv1/SetupV1Alpha.sh | bash ```

@assasinx93 composer doesn't define or enforce an endorsement policy.

davidkel (Fri, 14 Apr 2017 08:10:57 GMT):
@xixuejia I would check for errors when npm install was running. This problem usually occurs when something goes wrong trying to bring in dependent modules, for example if you don't have python 2.7 installed and set as the default python executable node-gyp can fail to work.

davidkel (Fri, 14 Apr 2017 08:12:51 GMT):
@MikeC711 you can get the logs for the containers using the docker logs. More info can be found at http://stackoverflow.com/questions/42695751/how-do-i-see-the-logs-for-fabric-composer/42695761#42695761

Try running `npm uninstall -g composer-cli` followed by `npm install -g composer-cli` and check that there are no install issues. Also delete the `node_modules` folder from getting started and then rerun `npm install`

it's Ok for me with a local version of playground connecting with hlfv1, is there instruction for this?

sstone1 (Fri, 14 Apr 2017 09:13:46 GMT):
Not yet, no. That tutorial demonstrates how to do it with the old blue and white UI which has connection profile + identity support needed to connect to HLF.

sstone1 (Fri, 14 Apr 2017 09:14:19 GMT):
We are still working on connection profile + identity support for the new UI (playground). When that is done we can document how to configure it with a local HLF, either v0.6 or v1.0.

xixuejia (Fri, 14 Apr 2017 09:14:47 GMT):

MikeC711 (Fri, 14 Apr 2017 16:08:08 GMT):
Thanks much. Will try that tonight. Quick semi-related question ... when I use the bluemix playground ... is that provisioning a small blockchain for me? Is there a connection json for that that I could use? Thanks,

assasinx93 (Fri, 14 Apr 2017 16:30:10 GMT):
@davidkel So does it mean that access control is what controls users creating and updating assets? Also, I worked on the play ground and simulated some simple asset creation, updation and deletion. How do you expand this to outside the playground? What I mean is that, if user X does not have access to updating an asset, then the entire admin console should not be visible to them right? Or do we have to create an angular app which supports this?

sstone1 (Fri, 14 Apr 2017 16:30:44 GMT):
@MikeC711 the Bluemix playground (composer-playground.mybluemix.net) uses an in-browser simulated blockchain; no real blockchain is provisioned.

sstone1 (Fri, 14 Apr 2017 16:30:55 GMT):
There is information on creating a connection.json for Bluemix here: http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service

sstone1 (Fri, 14 Apr 2017 16:32:59 GMT):
@assasinx93 whilst Composer doesn't define an endorsement policy, the default Fabric endorsement policy is in effect. The endorsement policy doesn't say who has access control to do what, it says who must execute the chaincode and "endorse" the transaction in order for it to be valid.

sstone1 (Fri, 14 Apr 2017 16:33:17 GMT):
You can use Composer access control (see permissions.acl) to restrict access to assets, participants, and transactions.

assasinx93 (Fri, 14 Apr 2017 16:35:43 GMT):
@sstone1 Thanks for the info. If you see my second question just above, I was wondering how we can deploy a fabric composer project to an actual network consisting of users logging in from multiple nodes. Every user should have a different view of the transactions they are able to perform. This has to be created by us right? I don't think there is any default portal for that.

sstone1 (Fri, 14 Apr 2017 16:37:23 GMT):
Correct, you will have to build a customized application for your end users. I would not expect anybody to be using Playground as an end user application.

sstone1 (Fri, 14 Apr 2017 16:38:08 GMT):
You can deploy a Composer business network definition to a Fabric instance using `composer network deploy`.

sstone1 (Fri, 14 Apr 2017 16:38:53 GMT):
Once deployed, you can create participants and issue those participants with identities (aka Fabric enrollment certificates). Access control is based on participants, so you'd need to define access control rules based on the participants in your business network.

sstone1 (Fri, 14 Apr 2017 16:39:51 GMT):
There's some documentation on participants and identities here: https://fabric-composer.github.io/introduction/participantsandidentities.html

assasinx93 (Fri, 14 Apr 2017 17:02:12 GMT):
Thanks

kletkeman (Fri, 14 Apr 2017 18:47:56 GMT):
Hi, could someone please explain what the difference is between these two definitions? asset Commodity identified by tradingSymbol { o String tradingSymbol o String description o String mainExchange o Double quantity --> Trader owner } asset Commodity identified by tradingSymbol { o String tradingSymbol o String description o String mainExchange o Double quantity o Trader owner }

kletkeman (Fri, 14 Apr 2017 18:50:31 GMT):
Also curious about registries. One of the docs talks about assets, participants, registries and transactions being what might be called the four pillars. But only three are explicitly declared while registries seem to be implied by other declarations. Can someone please explain the rules by which we can infer what the registries are based on the BND? Thanks.

sstone1 (Fri, 14 Apr 2017 19:33:58 GMT):
@kletkeman the first definition of the Commodity asset has a _relationship_ (denoted by -->) to a Trader participant that exists in the Trader participant registry. The second definition of the Commodity asset has a _property_ (denoted by o) of type Trader, and the data for that Trader is stored as part of the Commodity asset in the Commodity asset registry.

sstone1 (Fri, 14 Apr 2017 19:34:57 GMT):
We recently discussed banning `o AssetType` or `o ParticipantType` properties in an Asset, Participant, or Transaction and only permitting relationships to these types as it is a regular cause of confusion.

sstone1 (Fri, 14 Apr 2017 19:36:12 GMT):
If you want to include a complex structure in one of those types, you can use a `concept` instead.

sstone1 (Fri, 14 Apr 2017 19:37:42 GMT):
As for the registry question - registries are automatically created for every concrete (non-abstract) asset and participant type in a business network definition. Those automatically created registries are named after the fully qualified name of the type (namespace + type, e.g. org.acme.Vehicle). We have some APIs for creating custom registries, but these are not currently that useful as a lot of functionality does not work with custom registries.

@GoodFaith you seem to have copied the basic-sample-network **under** the my-network folder, rather than copying it into a new top level folder.

dselman (Sat, 15 Apr 2017 06:05:16 GMT):
I don't understand whether your issue is with the QuickStart or the Tutorial, or your comment "Didn't take long before it sunk in that the quick-start was a simulated test of the network" -- which is not true.

GoodFaith (Sat, 15 Apr 2017 06:08:16 GMT):
The quick-start doesn't perform the unit test? I used `cp -r ./sample-networks/packages/basic-sample-network/ ./my-network' to create the my-network folder, is that right?

GoodFaith (Sat, 15 Apr 2017 06:11:05 GMT):
Have not been able to perform the quick start. The error and log for that is on SO. What was posted here was at the unit test section of the tutorial.

dselman (Sat, 15 Apr 2017 06:13:45 GMT):
You need to be able to run the QuickStart cleanly first. Let's focus on that... I posted a couple of links in your SO question.

I tried using Jira to report a bug I found in the Composer test tool (the trash and edit button disappear when I hover over them, but reappear if I click the "collapse" button), however I didn't see any open Composer tickets on Jira. Where can I report this bug?

sstone1 (Sat, 15 Apr 2017 17:53:49 GMT):
@mohamoud.egal we don't use JIRA. We track Issues using GitHub.

mohamoud.egal (Sat, 15 Apr 2017 18:00:37 GMT):
@sstone1 thanks. Also in the car-auction network deployed from GitHub into Composer, what type is enum? I couldn't find it in the bna file.

sstone1 (Sat, 15 Apr 2017 18:01:50 GMT):
`enum` is a keyword that allows you to declare a typed enumeration (list of possible values) - I assume you mean this: https://github.com/fabric-composer/sample-networks/blob/master/packages/carauction-network/models/auction.cto#L11

mohamoud.egal (Sat, 15 Apr 2017 18:02:15 GMT):

MikeC711 (Sat, 15 Apr 2017 18:03:42 GMT):
@davidkel @sstone1 Thanks for the input. I had been running fine until I made some changes to try to accommodate HLF 1.0 ... (just software installs, not downloading and building yet). I had tried bumping the sleep 5 to sleep 25 ... but based on this, I moved all the way to sleep 185. I even tested every 30 seconds or so to verify that the peer log had not already hit the error. So up until 2 minutes in ... no error ... then when the 185 seconds had gone ... same error as ever. So while I could not figure out which start-hyperledger.sh to hit ... since that was only to further delay ... I'm quite certain that I'm waiting long enough now (especially since I was working without any additional delays before and I've provisioned some good horsepower for my Xenial VM on my RHEL host. Where I easily could have created a mess with a hybrid environment is that my file: ./dev/gitDev/sample-applications/packages/getting-started/scripts/start-hyperledger.sh makes references to hlfV1 (thinking I might have newer retrieve there). That said, it does not appear to me that the bringing up the containers should be notably impacted by that (but I will try to go back and re-pull). Will also try to go thru Dan's latest tutorial and see if that causes me to skip past it.

@sstone1 Another questions: the VehicleListing asset is defined in the Model file as having a reference to Vehicle, which has a Vin value and a reference to a Member. However, in the test field when I went to create a VehicleListing in the asset registry I clicked generate random data and didn't see any reference to Member. Why is that?

sstone1 (Sat, 15 Apr 2017 18:06:06 GMT):
@mohamoud.egal because the VehicleListing has a reference to the Vehicle, it only has the ID of the Vehicle - in that case "vin:8830"

sstone1 (Sat, 15 Apr 2017 18:06:23 GMT):
You will only see the reference to the Member by looking at the Vehicle in the Vehicle registry

sstone1 (Sat, 15 Apr 2017 18:08:56 GMT):
@MikeC711 anything in the membersrvc container logs?

MikeC711 (Sat, 15 Apr 2017 18:11:17 GMT):
@sstone1 No, my shell script pulls peer and memberservices (splitting out stdout and stderr) ... and the memberservices logs are empty ... and it is happily listening on port 7054.

sstone1 (Sat, 15 Apr 2017 18:11:56 GMT):
Have you modified the docker-compose.yml file at all?

sstone1 (Sat, 15 Apr 2017 18:14:02 GMT):
I can only imagine those errors are caused by the peer not being able to communicate with membersrvc. You could try checking the network: ``` $ docker exec -ti docker_vp0_1 sh <-- start shell in peer container # nc membersrvc 7054 <-- attempt to access membersrvc port ```

MikeC711 (Sat, 15 Apr 2017 18:34:50 GMT):
Have not modified docker-composer but ... the nc command gets me: # nc membersrvc 7054 nc: getaddrinfo: Name or service not known That looks like the gethostname type call that won't use /etc/hosts ... although /etc/hosts looked fine. So I did hostname and nslookup and that appeared to be fine: mcasile@mcasile-KVM:~/dev/blockchain/docker$ hostname mcasile-KVM mcasile@mcasile-KVM:~/dev/blockchain/docker$ nslookup mcasile-KVM Server: 127.0.1.1 Address: 127.0.1.1#53 Name: mcasile-KVM.default Address: 192.168.122.80 But that failure on getaddrinfo seems problematic, although if it looking for host membersrvc unless some network magic is happening, that would not work. I am guessing that somehow membersrvc is supposed to be known in the peer address space because docker-compose.yml created the link ... but I'm out of my depth there.

sstone1 (Sat, 15 Apr 2017 18:38:02 GMT):
Yeah, docker should be making the membersrvc hostname available to the peer container

sstone1 (Sat, 15 Apr 2017 18:38:11 GMT):

Had some trouble w/compose when I played a bit with HLF V1 ... the SSLV3 error message, so I had to do some scrambling to make that go away.

sstone1 (Sat, 15 Apr 2017 18:40:54 GMT):
In that SO link @davidkel posted earlier, he mentioned: > Could you try downgrading docker-compose to 1.11 ? I have seen problems with 1.12 and it may be the cause.

sstone1 (Sat, 15 Apr 2017 18:41:12 GMT):
I have: ``` Simons-MacBook-Pro-3:~ sstone1$ docker -v Docker version 17.03.0-ce, build 60ccb22 Simons-MacBook-Pro-3:~ sstone1$ docker-compose -v docker-compose version 1.11.2, build dfed245 ```

MikeC711 (Sat, 15 Apr 2017 18:42:32 GMT):
I will try to downgrade ... and hope that the SSLV3 does not return. Odd that docker-compose would lose that crucial a function ... but I will try ... and hopefully not throw myself into the SSLV3 issue again.

MikeC711 (Sat, 15 Apr 2017 18:58:50 GMT):
Well, it's all good news. Sorry to have taken your time. I was dreading going back thru the resoluton of the SSLV3 module issue, but apparently the upgrade of the url package handled that w/out the change to docker-compose. So I am back in business ... thanks much.

kletkeman (Sat, 15 Apr 2017 19:02:38 GMT):
@sstone1 Thanks for the reply. So when I have a relationship to a Trader in my Commodity, I presume that I would need to do a second read to get the Trader object if I chose to manipulate it for some reason. I.e. it is not automatically retrieved for me from the Trader registry. It basically acts as a foreign key.

sstone1 (Sat, 15 Apr 2017 19:02:54 GMT):
Great, no problem. @davidkel we need to get to the bottom of the Compose 1.12 issue. It looks like they changed some networking stuff as `--link` is deprecated.

kletkeman (Sat, 15 Apr 2017 19:03:30 GMT):
@sstone1 Second question then, is it acceptable to create a relationship to an array of Traders? --> []Trader traders ?

sstone1 (Sat, 15 Apr 2017 19:05:35 GMT):
@kletkeman correct, it is a foreign key. However, relationships in a `transaction` object are automatically resolved before executing a transaction processor function. For example: ``` transaction MyTransaction { --> Vehicle vehicle } function onMyTransaction(transaction) { transaction.vehicle.colour === 'RED'; // vehicle relationship automatically resolved } ```

kletkeman (Sat, 15 Apr 2017 19:06:13 GMT):
@sstone1 That's cool, I should have noted that from the samples. Thanks.

sstone1 (Sat, 15 Apr 2017 19:06:19 GMT):
Everywhere else (e.g. when you use `get(id)` or `getAll()`) you must manually resolve the relationships.

sstone1 (Sat, 15 Apr 2017 19:06:35 GMT):
Also, yes, you can have an array of relationships... `--> Trader[] traders`

kletkeman (Sat, 15 Apr 2017 19:06:48 GMT):
Excellent, thanks!

sstone1 (Sat, 15 Apr 2017 19:08:54 GMT):

davidkel (Sat, 15 Apr 2017 22:41:19 GMT):
@sstone1 I know that docker-compose required an updated urllib3 package on trusty. However while testing a new vagrant image I installed docker-compose 1.12 though pip and that's when my V1 docker-compose images stopped working. Downgrading to 1.11.2 fixed the problem but I haven't as yet looked into why and I'd only tried it on trusty. The errors I saw were containers not starting at all due to some odd error messages but not necessarily indicating wrong levels of python libraries. I only mention downgrading just to eliminate possible problems introduced to the docker-compose 1.12 release which I would have expected to be backward compatible

@ztanaka1971 did you clone sample-applications or sample-applications-hlfv1 ? The first should use fabric 0.6 and the second should use fabic 1.0 alpha. If you do the second one then the getting-started has a readme which has some extra steps to perform first.

@ztanaka1971 just looked at it and it appears it has been updated to hlf v1 alpha. I think that is an issue as there is a separate sample-applications specifically for hlf 1.0 alpha and sample-applications should still be at 0.6

Sure

davidkel (Mon, 17 Apr 2017 13:27:12 GMT):
@gauthampamu I have also made changes to the hlfv1 version of sample-applications so that it now creates a connection profile for you (before you had to follow some instructions to do it manually) also it creates a profile called hlfv1 so that it doesn't conflict with defaultProfile

I have four or five profiles..in the directory. I had tried your script for v1.0 so I do have hlfv1 profile but I am assuming it should not conflict with defaultprofile

Hi with the new tutorial, would I be able to use this to generate the code that I ultimately can deploy to a Bluemix Hyperledger Fabric v.6 service instance. Thanks!

tennenjl (Mon, 17 Apr 2017 17:01:23 GMT):
For the new tutorial found here: https://github.com/dselman/fabric-composer/wiki/Tutorial-2-:-Creating-a-Fabric-Composer-Solution I am receiving an error during the execution of the unit tests. 1) Commodity Trading #tradeCommodity should be able to trade a commodity. I am receiving the error: Error: Could not find any functions to execute for transaction org.acme.mynetwork.Trade#2d66a28c-d0fe-4372-a868-58373ae4ce14. Just checking to see if anyone was able to execute the unit tests. Thanks!

Readme for the car auction should be updated. User is abstract participants so you cannot use it to create the User. Create Your Participant & Issue an Identity Card Switch to the Test tab, then click on the User participant registry, then click on the Create Participant button to create a new instance of a user. The JSON representation of the User should be: { "$class": "org.acme.vehicle.auction.User", "email": "daniel.selman@uk.ibm.com", "firstName": "Daniel", "lastName": "Selman", "balance": 10000 } It should be changed to auction.member

sstone1 (Mon, 17 Apr 2017 17:33:28 GMT):
@tennenjl you should be able to deploy whatever you build with Composer to the IBM Blockchain service running on Bluemix. There are instructions for creating a Bluemix connection profile here: http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service

sstone1 (Mon, 17 Apr 2017 17:33:55 GMT):
That error suggests that the JavaScript transaction processor function does not have the right comments: ``` /** * Track the trade of a commodity from one trader to another * @param {org.acme.mynetwork.Trade} trade - the trade to be processed * @transaction */ function tradeCommodity(trade) { ```

sstone1 (Mon, 17 Apr 2017 17:34:22 GMT):
The @param and @transaction are how we find which JavaScript functions to execute for any given transaction.

tennenjl (Mon, 17 Apr 2017 17:35:37 GMT):
@Sstone1 Thank you so much. Yes, and that stack overflow is great, but for that approach I was using the older composer-ui, (because of the connection profile issue) so I was wondering if I use the tutorial with the newer version, whether that would get me in trouble, when it came to getting those artifacts up to Bluemix

tennenjl (Mon, 17 Apr 2017 17:36:04 GMT):
thanks, I'll check my comment

sstone1 (Mon, 17 Apr 2017 17:37:00 GMT):
@mohamoud.egal your errors are usually a sign that Fabric is not running, has crashed, or is the wrong version (v0.6/v1.0) to what your connection profile is expecting.

sstone1 (Mon, 17 Apr 2017 17:38:09 GMT):
@gauthampamu you are quite right; fancy raising a GitHub issue on the sample-networks repository?

tennenjl (Mon, 17 Apr 2017 17:40:55 GMT):
@sstone1, so I while I have been able to deploy to Bluemix using the older composer-ui version, I am not sure what is the best approach (or if it is possible) to use the newer tooling and capabilities and still ultimately get my chaincode deployed to Bluemix Hyperledger Fabric v.6 instance.

sstone1 (Mon, 17 Apr 2017 17:42:26 GMT):
Gotcha. Until the Playground supports connection profiles (at which point it will support Fabric running anywhere, including Bluemix), you will need to use the `composer` command line. You will want to use the `composer network deploy` command.

sstone1 (Mon, 17 Apr 2017 17:43:40 GMT):
The command line uses the same connection profiles that the Playground does. They have to be in JSON format: `~/.composer-connection-profiles//connection.json`, e.g. the getting started guide creates the defaultProfile connection profile as `~/.composer-connection-profiles/defaultProfile/connection.json`

tennenjl (Mon, 17 Apr 2017 17:44:34 GMT):
ah fantastic, so if I am following, that means I could potentially create and model my artifacts and transactions using the new tooling and then use command line to deploy to Bluemix?

tennenjl (Mon, 17 Apr 2017 17:44:43 GMT):
and thank you :-D

sstone1 (Mon, 17 Apr 2017 17:46:04 GMT):
Correct - you should just be able to export the BNA from the Playground and then deploy it to Bluemix using the command line.

tennenjl (Mon, 17 Apr 2017 17:46:42 GMT):
fantastic. Thank you!!

jwalt (Mon, 17 Apr 2017 18:06:55 GMT):
In the Understanding Business Networks section of the documentation there's a statement about registries: 'Registries. A registry is a collection of assets for a particular purpose. As assets move through their lifecycle, they move through different registries. Assets can be in more than one registry at the same time.' I know that registries are automatically created for each asset type, but how then can assets move through different registries or be in more than one registry at the same time? Is this a not-yet-documented feature or what am I missing?

sstone1 (Mon, 17 Apr 2017 18:10:06 GMT):
The JavaScript APIs allow you to create new, custom registries and also allow you to add any asset/participant type to any registry.

sstone1 (Mon, 17 Apr 2017 18:10:26 GMT):
Unfortunately at present, not a lot of functionality works if you do that, which is why you don't see it talked about much in the docs ;)

sstone1 (Mon, 17 Apr 2017 18:10:34 GMT):
But it's where we want to get to.

jwalt (Mon, 17 Apr 2017 18:12:02 GMT):
ok, thanks for the quick reply

rogeriofza (Mon, 17 Apr 2017 20:40:31 GMT):
Hi, I have come across the transaction .js files and watched a video where its linked to the Codechain capabilities of the Hyperledger fabric. I have also then seen it being associated or categorized with the term Smart Contracts , possibly because of the Access Control List (ACL). Can we expect in future the introduction of Smart Contract model objects to best represent the notion of actual smart contracts. I feel fabric-composer is down playing this slightly as a first class citizen conceptually. Its a little bit of the sum of its parts at this stage. Your thoughts? Do you think there will be an elegant way of introducing "contracts" that participants have to abide by.

dselman (Mon, 17 Apr 2017 20:51:49 GMT):
My opinion on "smart contracts" https://blog.selman.org/2016/09/26/smart-contracts-not-smart-not-contracts/

dselman (Mon, 17 Apr 2017 20:52:29 GMT):
Yes, we can do much better than this with Fabric Composer... We've no concrete plans at present but lots of aspirations! :-)

rogeriofza (Mon, 17 Apr 2017 21:42:44 GMT):
Many thanks for sharing your blog post. I fully agree with most of your points, in particular "we need much more focus on the contract requirements of business networks" and "current incarnations of 'Smart Contracts' needs serious evolution and refinement" - that is what made me post in the first place. Just feels we relying on the technical implementation of 'transactions' to justify we indeed are upholding 'contracts' in a business network. The disconnect is very real . Did a small test with with a non-technical colleague. He bought into the whole model, but the very context of business network without established contracts as a concept was perplexing. The jump straight into transactions and access control...was already questions around context of why they exist? We live in hope that those aspirations get addressed soon so we don't travel too far without the appropriate foundation.

rogeriofza (Mon, 17 Apr 2017 21:43:59 GMT):

@sstone1 1) I launched Fabric in this directory: fabric-sdk-node/test/fixtures using "docker-compose up --force-recreate". 2) Then I ran the command "composer network deploy -a my-network.bna -i admin -s Xurw3yU9zI0l" in the directory: /Users/mohamoudegal_ibm/Desktop/playground/my-network/dist where my .bna file is.

hey guys, have encountered another possible model inheritance problem. Can anyone provide any futher insight on https://github.com/fabric-composer/fabric-composer/issues/696 for me? Is this intentional? If so, what's the recommended way of retrieving the participant from the saved relationship after storage?

dselman (Tue, 18 Apr 2017 07:01:43 GMT):
IMO this is a bug but I would like to hear @sstone1 view on this as well

dselman (Tue, 18 Apr 2017 07:01:43 GMT):
This sounds like the approach we demo in the Perishable Good Network: https://github.com/fabric-composer/sample-networks/tree/master/packages/perishable-network

sstone1 (Tue, 18 Apr 2017 07:17:23 GMT):
Yeah, we need to do a lot of work on relationships. #469 is related.

pospi (Tue, 18 Apr 2017 07:43:21 GMT):
It manifests differently if the relationship is setup outside of the composer runtime, I've added a stack trace to the issue with that info.

pospi (Tue, 18 Apr 2017 07:44:10 GMT):
@sstone1 if you have any pointers on where to start looking I might see if I can fix it as this is a significant problem for us in our network which we don't really have any good workarounds for

sstone1 (Tue, 18 Apr 2017 07:45:38 GMT):
Sure, will take a look and update the issue with some thoughts/pointers

pospi (Tue, 18 Apr 2017 07:58:45 GMT):
@sstone1 It may be kinda simple actually. If you specify a relationship type which isn't part of the correct inheritance graph then it correctly gives errors like `Instance test.net.model.TestAsset#a1ea3de0-240c-11e7-87b5-915ca8544965 has property invoker with type test.net.model.AdminParticipant that is not derived from test.net.model.TestParticipant`

Understand for node app, you can add DEBUG=composer:* but is the configuration for command line tool. Where should we configure tracing for CLI

vinitesh (Tue, 18 Apr 2017 14:21:14 GMT):
Hello, Is the v1 has backward compatibility with v0.6. Means whatever network/.bna i built and tested in v0.6 will also run in v1?

sstone1 (Tue, 18 Apr 2017 14:23:29 GMT):
@vinitesh yes, the same business network definition will run on v0.6 and v1.0 without changes.

sstone1 (Tue, 18 Apr 2017 14:23:53 GMT):
@gauthampamu the DEBUG=composer:* environment variable applies to both the Node.js APIs and the CLI

@jorgedr all of the planned work is being tracked on GitHub. You can see a bit of a roadmap on the Projects tab here: https://github.com/fabric-composer/fabric-composer/projects

jdockter (Tue, 18 Apr 2017 15:35:36 GMT):
@sstone1 a question was raised to our team about setting up some configurable busn rules for our network...do you see any issue with creating an asset, ie BusnRules, that would store off specific values that could be leveraged by transactions to then do different types of busn logic based on the stored values? Thinking we would lock them down by ACL so only certain participants could update. Also, wondering if there would be a way to bootstrap those to the deploy of the network? Or maybe there is a better alternative?

dselman (Tue, 18 Apr 2017 16:41:21 GMT):
@jdockter this sounds like what we demo here: https://github.com/fabric-composer/sample-networks/tree/master/packages/perishable-network

dselman (Tue, 18 Apr 2017 16:41:59 GMT):
I think this is a powerful technique to externalize parameter values

dselman (Tue, 18 Apr 2017 16:42:42 GMT):
You can model a transaction to update the values.

jdockter (Tue, 18 Apr 2017 16:50:16 GMT):
@dselman so your referring to the Contract asset? When you say externalized...you just mean that a transaction would run to populate it with different values or am I missing something?

dselman (Tue, 18 Apr 2017 16:50:36 GMT):
Correct.

dselman (Tue, 18 Apr 2017 16:51:29 GMT):
The TP functions are essentially a template for a contract, with the contract asset holding the parameter values for a specific instance of the contract.

jdockter (Tue, 18 Apr 2017 16:53:57 GMT):
okay thanks

@dselman so instead of deploying the .bna to Fabric instance locally I should deploy the .bna to a Fabric instance on Bluemix?

dselman (Tue, 18 Apr 2017 17:18:04 GMT):
exactly

dselman (Tue, 18 Apr 2017 17:18:20 GMT):
you just need to create a connection profile document with the right URLs etc

jdockter (Tue, 18 Apr 2017 17:26:52 GMT):
@dselman if we running some system tests and want to reset network before we start...is there away to leverage the API to do that? I'm not seeing it, but know you have the capability in the playground so guessing I'm missing something.

dselman (Tue, 18 Apr 2017 17:32:39 GMT):
We do have an internal method. @sstone1 -- any way to call that?

davidkel (Tue, 18 Apr 2017 17:34:15 GMT):
@jdockter If you look at testutil.js in the systest directory in the composer-systests package there is a method called resetBusinessNetwork, you should be able to copy the code from there

davidkel (Tue, 18 Apr 2017 17:35:25 GMT):
``` const Util = require('composer-common').Util; return Util.invokeChainCode(client.securityContext, 'resetBusinessNetwork', []); ``` something like that, but I've not tried it

Its sorted out. After poking around a bit and not finding much, I went ahead, uninstalled hfc(0.6) rebooted and started a fresh npm install and it worked.

Suma (Tue, 18 Apr 2017 22:18:00 GMT):
frankly dont see how it got resolved. i dont see how thats a solution

@Suma if you are running the hlfv1 sample then the connection profile to use is called hlfv1, also the enrollid is admin and enrollsecret is adminpw

Hi, So I ran through the Creating a Fabric Composer Solution lab and was excited to see the rest server and loopback feature. I was wondering if I can create my own loopback project and then leverage the composer loopback connector to generate APIs and create a microservice that I could deploy to Bluemix? Just to add a bit more, so if I run npm install to add the loopback-composer-connector and if I then define the connector to the datasource.json with the appropriate attributes (connectionProfileName, businessNetworkAdapter, businessNetworkIdentifier, participantId, and participantPwd), is it possible to generate the swagger APIs, and a microservice that I can then publish?

MikeC711 (Wed, 19 Apr 2017 00:44:19 GMT):
Apologies for what might be a non-technical request. All is working well w/my business network in the playground and I'll soon expand but ... I'll generate the REST and drive that from several different node applications (one application for each organization). One org is a bank ... and I might have different people who have different Identities at the bank. Is there a common/preferred pattern by which when Banker1 is using the app, the REST requests come in with their eCert/tCert ... and when Banker2 is driving the app ... the REST requests com in with theirs (even though the app itself is the same)? I'm going back thru the excellent tutorial on participants, IDs, et al ... and I don't see it in there (maybe this question is too basic) ... but if anyone has thoughts on best way to handle that, I would greatly appreciate it. Thanks,

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=5MEDT4irjLgDnFYS9) @tennenjl yes, the Composer Loopback connector is just that -- a standard Loopback Connector. You can use it with all the Loopback tools. We've just wrapped the Loopback tools to create the composer-rest-server, you can use the Loopback framework yourself with the Composer connector for more control.

dselman (Wed, 19 Apr 2017 05:17:25 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=gFaRyHGiaAL9wNqpv) @MikeC711 Excellent question, glad to see you are making good progress. We are building out support for authentication to the REST API, which will include the ability to authenticate to the REST server using Passport.js, and associating an ECert with the authenticated user. @sstone1 is leading this work and the design is described here: https://github.com/fabric-composer/fabric-composer/issues/142

pospi (Wed, 19 Apr 2017 07:03:19 GMT):
can anyone tell me if there's a way to update the submitted transaction from within its transaction handler callback? Or is the payload set in stone once it gets this far?

pospi (Wed, 19 Apr 2017 07:15:42 GMT):
related- what about creating another transaction from within a transaction handler?

dselman (Wed, 19 Apr 2017 09:45:24 GMT):
Nothing prevents you modifying the transactions being processed inside your TP function. Yes, you can create a new transaction inside a TP function, however we do not yet have an `emit` API to cause the runtime to process the transaction. There is a story open for that.

tennenjl (Wed, 19 Apr 2017 13:37:07 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=67BB9aS6ojPdDqJjW) @dselman Thank you so much! So, as a novice, once I have defined the datasource, in the past I have defined a model with attributes, but in this case, I assume there is some other approach to generate the schema. Any hints on how I would do that? Thank you again!

dselman (Wed, 19 Apr 2017 13:38:08 GMT):
The LB model is automatically generated by the composer loopback connector from your Composer model. So just deploy your business network!

tennenjl (Wed, 19 Apr 2017 13:38:47 GMT):
@dselman, wow, ok, I'll give that a try. Thanks!

Suma (Wed, 19 Apr 2017 14:22:25 GMT):
HOw do we do eventhub with composer - generate chaincode events and listen to them?

@Suma we don't yet support that. It is being tracked as this story: https://github.com/hyperledger/composer/issues/66

jorgedr (Wed, 19 Apr 2017 15:35:39 GMT):
Yes @sstone1 , it is based on Fabric v.6 so it is a little challenging since things are moving so fast on the v1.0 arena for composer but so far it is working very well for us.

davidkel (Wed, 19 Apr 2017 18:32:28 GMT):
@jinvanstee if you go to the fabric composer website at https://fabric-composer.github.io/ and click on the 'playground' option at the top it will take you to an online version of the fabric composer playground application

jinvanstee (Wed, 19 Apr 2017 18:32:33 GMT):
Ok I installed the fabric composer playground locally .. it says i can connect to an existing hyperledger fabric but i don't see directions on how to do that

jinvanstee (Wed, 19 Apr 2017 18:32:34 GMT):
If you have an existing Hyperledger Fabric instance you want to use with Fabric Composer Playground, then you can install the playground without installing another Hyperledger Fabric instance. The playground can then be configured to connect to your existing Hyperledger Fabric instance by creating a connection profile with the required connection settings.

[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=ZQ8Q6yCqD24LmJTt9) @dselman Sorry to ask, but I'm still missing something. So lets say I am starting from scratch. First I create my project via apic loopback command. 2) I then install the loopback adapter via npm i loopback-connector-composer --save, then I edit the server/datasources.json and add my datasource def which looks similar to this: { "testDS": { "name": "testDS", "connector": "composer", "connectionProfileName": "bluemixHRProfile", "businessNetworkIdentifier": "my-network", "participantId": "user_type1_0", "participantPwd": "1234567" } }

sstone1 (Wed, 19 Apr 2017 18:53:39 GMT):
@jinvanstee sorry, the docs are a bit misleading. We have an old UI, `composer-ui`, that supports connections to Hyperledger Fabric. What you've downloaded is the new UI, or Playground, `composer-playground` which does not support support connections to Hyperledger Fabric. The team is busy porting the functionality to the new UI and we hope to make this available in the next couple of weeks.

sstone1 (Wed, 19 Apr 2017 18:54:27 GMT):
@AlexKim that error can be safely ignored; I believe it means "some client connected to the event hub, but forgot to properly disconnect before closing the connection"

jinvanstee (Wed, 19 Apr 2017 18:56:17 GMT):
@sstone1 appreciate it.. yeah i saw the stackoverflow thread on getting the old composer-ui

AlexKim (Wed, 19 Apr 2017 18:56:26 GMT):
@sstone1 Thanks a lot - I got that error when tried to use remote fabric with modified version of composer profile - maybe I missed something? Is there any good example how to configure profile with remote version of fabric?

sstone1 (Wed, 19 Apr 2017 18:58:04 GMT):
It's probably an issue in Composer that means we don't call `eventHubDisconnect()` when the program shuts down

sstone1 (Wed, 19 Apr 2017 18:58:24 GMT):
The error shouldn't effect functionality - are you getting any other errors ?

jinvanstee (Wed, 19 Apr 2017 18:59:42 GMT):

sstone1 (Wed, 19 Apr 2017 19:02:12 GMT):
Ah, OK. That means that WebAppAdmin has already been enrolled somewhere.

jinvanstee (Wed, 19 Apr 2017 19:02:31 GMT):
i see

sstone1 (Wed, 19 Apr 2017 19:02:47 GMT):
You can only use the enrollment ID + secret once, and you get an enrollment certificate back - which in Composer's case, gets placed into that keyValStore directory.

jinvanstee (Wed, 19 Apr 2017 19:02:47 GMT):
should have masked the IP address of our test fabric .. argh

jinvanstee (Wed, 19 Apr 2017 19:02:58 GMT):
i see

sstone1 (Wed, 19 Apr 2017 19:03:17 GMT):
The enrollment secret is ignored for subsequent commands as the enrollment certificate is retrieved from the keyValStore directory.

sstone1 (Wed, 19 Apr 2017 19:03:39 GMT):
If you delete the certificate, then it attempts to re-enroll, which will fail (unless you recreate the Fabric)

sstone1 (Wed, 19 Apr 2017 19:03:58 GMT):
If you recreate the Fabric, you also need to delete any old certificates that were enrolled using that Fabric instance.

sstone1 (Wed, 19 Apr 2017 19:03:58 GMT):
If you recreate the Fabric, you also need to delete any old certificates that were enrolled using the old Fabric instance.

AlexKim (Wed, 19 Apr 2017 19:04:35 GMT):
yes @sstone1 it was deployed once on local fabric, and created keyvalstore....now makes sense to delete it and deploy to remote fabric again for new keyvalstore

AlexKim (Wed, 19 Apr 2017 19:05:08 GMT):
so everytime deploying to new fabric

sstone1 (Wed, 19 Apr 2017 19:05:14 GMT):
one thing I usually do is change `keyValStore` to include the connection profile name, e.g. `"keyValStore": "/Users/jinvanstee/.composer-credentials/remoteFabric1",`

sstone1 (Wed, 19 Apr 2017 19:05:36 GMT):
Then the certs are always kept in a directory for a specific Fabric

sstone1 (Wed, 19 Apr 2017 19:06:02 GMT):
I think we need to make that the default behaviour as otherwise you hit these kind of problems

sstone1 (Wed, 19 Apr 2017 19:20:20 GMT):
@tennenjl you need a LoopBack boot script to drive the discovery of the business network and register the models with LoopBack. For example, this is the LoopBack boot script that `composer-rest-server` uses: https://github.com/hyperledger/composer/blob/master/packages/composer-rest-server/server/boot/composer-discovery.js

sstone1 (Wed, 19 Apr 2017 19:20:57 GMT):
I think you care about the code from line 486 down (`discoverModelDefinitions`).

sstone1 (Wed, 19 Apr 2017 19:20:57 GMT):
I think you care about the code from line 486 down - `discoverModelDefinitions()`

sstone1 (Wed, 19 Apr 2017 19:21:50 GMT):
Alternatively, you could just use `composer-rest-server` which takes care of it for you ;)

tennenjl (Wed, 19 Apr 2017 19:23:11 GMT):
@simonstone Thanks! Will take a look. My challenge is that I need to have my rest server/API running in Bluemix, so as far as I can tell, that means either installing composer-rest-server in a docker container and deploying that to Bluemix, or generating the API/Microservice locally and publishing it.

sstone1 (Wed, 19 Apr 2017 19:24:53 GMT):
Ah gotcha. You're going to hit some tough problems deploying the REST server in a production environment though - mainly around enrollment certificates.

sstone1 (Wed, 19 Apr 2017 19:25:37 GMT):
Because you can only enroll once, and the enrollment certificates (by default) are stored in the local file system - you need to persist the enrollment certificates somewhere else if you want to scale your REST server (multiple instances) or allow it to work across restarts etc

sstone1 (Wed, 19 Apr 2017 19:26:37 GMT):
I've been working on some changes to the REST server recently to make it a lot easier - you can configure it to store the enrollment certificates in a database such as MongoDB.

tennenjl (Wed, 19 Apr 2017 19:55:59 GMT):
@sstone1, thanks. Sounds like another challenge that we may have fun with.

@tennenjl @sstone1 we usually just copy our enrolment certificates between hosts, that works just fine. I like to configure the credentials path to be under the connection profile directory so you can just `scp` the whole folder across. You likely have the same user (like `ubuntu`) between hosts, but if not I just make a sed script to replace the path in `connection.json`

karthikworks (Thu, 20 Apr 2017 08:48:19 GMT):
Any idea on how do i do that ?

karthikworks (Thu, 20 Apr 2017 08:49:06 GMT):
But this is the latest composer..

karthikworks (Thu, 20 Apr 2017 08:49:27 GMT):
oh sorry you were addressing a different issue... my bad..

paul.sitoh (Thu, 20 Apr 2017 09:17:45 GMT):
Which version of composer?

paul.sitoh (Thu, 20 Apr 2017 09:18:07 GMT):
npm @

paul.sitoh (Thu, 20 Apr 2017 09:18:07 GMT):
npm @?

sstone1 (Thu, 20 Apr 2017 09:21:58 GMT):
I think it should be in v0.5.6

paul.sitoh (Thu, 20 Apr 2017 09:22:02 GMT):
I need to maintain two version in case people still working on older one

sstone1 (Thu, 20 Apr 2017 09:23:21 GMT):
@ZenX0904 you can implement this easily using transaction processor functions. You code the transfer of the asset by changing the value of the `originalOwner` and `currentOwner` properties.

sstone1 (Thu, 20 Apr 2017 09:26:35 GMT):
@mohamoud.egal where to get those values is documented on the SO question: > The hostname and port numbers in the URLs must come from the Bluemix dashboard. I find it easiest to get this information by navigating to "Service Credentials" and viewing the default credentials "Credentials-1". That is followed by a description of how the Bluemix properties map to the Composer properties.

sstone1 (Thu, 20 Apr 2017 09:29:46 GMT):
@karthikworks that error is a communication error, which means that you have specified the wrong port or Fabric is not available or Fabric has crashed.

sstone1 (Thu, 20 Apr 2017 09:30:02 GMT):
Are you using Fabric v0.6 or Fabric v1.0?

karthikworks (Thu, 20 Apr 2017 09:36:39 GMT):
I think i am using v0.6

sstone1 (Thu, 20 Apr 2017 09:37:45 GMT):
Are you running it using Docker?

karthikworks (Thu, 20 Apr 2017 09:49:37 GMT):
Yes...

karthikworks (Thu, 20 Apr 2017 09:50:03 GMT):
I found one issue... the ports were wrong..changed that and i did not get the above said error..

karthikworks (Thu, 20 Apr 2017 09:50:14 GMT):
but instead... its taking time to deploy..

sstone1 (Thu, 20 Apr 2017 09:50:42 GMT):
can you run `docker logs` on the peer docker container (probably called vp0)

karthikworks (Thu, 20 Apr 2017 09:54:53 GMT):
Ok... so when i run the deploy... it starts of correctly but.. i can see these errors on the logs...

Suma (Thu, 20 Apr 2017 12:11:35 GMT):
Hi, I'm trying to connect the getting-started v 0.6 example to bluemix fabric, which was working perfectly fine a week back. Since y'day, with a fresh copy, when i try to deploy on Bluemix I get 'TypeError: Cannot read property 'fail' of undefined Command failed' Tried a few times, can't see what I'm doing wrong. any tips pls?

davidkel (Thu, 20 Apr 2017 12:19:20 GMT):
@Suma That error usually indicates either a problem with your connection profile or a problem with your archive file (if you get as far as having details of your archive being output then it is a problem with the connection profile)

Suma (Thu, 20 Apr 2017 12:19:54 GMT):
I'm using the same connection profile I used a week back. lemme paste the details here...

that's all i see in the command line

davidkel (Thu, 20 Apr 2017 12:33:55 GMT):
unfortunately due to a bug introduced into 0.5.10 the actual error isn't output anywhere. Your connection profile that you posted looks ok. The issue has been fixed but we haven't published a stable version with it in. The unstable versions should have the fix

davidkel (Thu, 20 Apr 2017 12:35:14 GMT):
so you could try `npm install -g composer-cli` followed by `npm install -g composer-cli@unstable` which hopefully would then output the error message at least

davidkel (Thu, 20 Apr 2017 12:35:14 GMT):
so you could try `npm uninstall -g composer-cli` followed by `npm install -g composer-cli@unstable` which hopefully would then output the error message at least

Suma (Thu, 20 Apr 2017 12:35:27 GMT):
ok. lemme try that. thanks.

Sorry, that didn't help. This is what I did. Fresh folder, removed all my docker images and containers, nvm use v6*, renamed my .composer-connection-profiles folder to .old-composer-connection-profiles, ran npm install -g composer-cli, npm install -g composer-cli@unstable, git clone https://github.com/fabric-composer/sample-applications.git, cd sample-applications/packages/getting-started $ npm install $ composer network list -n digitalproperty-network --enrollId WebAppAdmin --enrollSecret DJY27pEnl16d

Suma (Thu, 20 Apr 2017 13:03:14 GMT):
all good so far. Then I try composer network deploy --archiveFile digitalPropertyNetwork.bna --enrollId admin --enrollSecret c8f40dadd6 -p bluemixProfile (bluemixProfile is a copy of the same profile file I shared earlier, now saved in the newly created .composer-connection-profiles folder

When I tried the v1 version of getting started, a couple of days back, it ran just fine. And I see this version of getting started has had recent updates. Do you think its looking for some v1 behavior / modified connection profile (v1 compatible) - hfc keystore kind?

Suma (Thu, 20 Apr 2017 13:14:14 GMT):
both run locally, the 0.6 version, that can run against bluemix doesn't run now.

davidkel (Thu, 20 Apr 2017 13:15:54 GMT):
@suma could you get the version levels you have installed of composer-cli `composer-cli --version`

davidkel (Thu, 20 Apr 2017 13:17:34 GMT):
sorry my initial instructions were wrong the first part should have been `npm uninstall -g composer-cli` (not install)

I have a local instance of playground with the docker-compose.yml pulled down from the link at https://fabric-composer.github.io/tutorials/getting-started-playground.html#installationoptions .

sstone1 (Thu, 20 Apr 2017 14:22:35 GMT):
if you use the unstable version, you need to use the same version everywhere

davidkel (Thu, 20 Apr 2017 14:34:10 GMT):
@Suma so by using the unstable version it's not reported any errors now with your connection profile or setup which was the only reason for you to try unstable. I suggest you now uninstall that level of composer-cli and return back to the stable version

sstone1 (Thu, 20 Apr 2017 17:33:21 GMT):
@gromeroar unless you enabled security (which is a new undocumented feature) you shouldn't need an access token

Hey guys, did you add new versions for the composer-* npm packages?

dselman (Thu, 20 Apr 2017 18:10:32 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=oJrtTBGfzzYtuJQaK) @dkneisly the preferred mechanism is to add the `@transaction` annotation and then use an `@param` annotation for the type of the transaction.

dselman (Thu, 20 Apr 2017 18:10:40 GMT):
(see the docs)

sstone1 (Thu, 20 Apr 2017 18:18:45 GMT):
@jorgedr new version went up, another new one is going up imminently (0.5.12)

jorgedr (Thu, 20 Apr 2017 18:22:00 GMT):
Curious, are those new versions compatible with Fabric v.6?

sstone1 (Thu, 20 Apr 2017 18:22:18 GMT):
Yep, we're not dropping v0.6 support any time soon.

sstone1 (Thu, 20 Apr 2017 18:22:45 GMT):
We want to wait for v1.0 to stabilise, and for our v1.0 support to get a bit more testing by the community.

jorgedr (Thu, 20 Apr 2017 18:25:44 GMT):
Cool.. One thing I did notice, in our package.json we were setting the required version for the composer packages as ^0.5.10 which I think it means install that version or a compatible one but the npm install started failing when you guys made the change. As soon as I removed ^ it started working again. I will look into it later to see if the error persisted. The error was about the version of npm being used not compatible with the packages being installed. But it looked as if it were coming from a dependency of the new composer packages and not necessarily for the composer packages itself.

sstone1 (Thu, 20 Apr 2017 18:38:27 GMT):
Oh that's odd... Node 6?

sstone1 (Thu, 20 Apr 2017 18:38:31 GMT):
We only support Node 6

jorgedr (Thu, 20 Apr 2017 18:48:17 GMT):
Well, this was the first time that we were trying to push our application into a Bluemix Node.Js CloudFoundry instance. So I am not sure what version of node the buildpack uses. I left it alone for now because I did not want to open that can of worms

jorgedr (Thu, 20 Apr 2017 18:49:35 GMT):
What I do know is that as soon as we started specifying explicitly the 0.5.10 version (vs ^0.5.10 ) it started working.

sstone1 (Thu, 20 Apr 2017 18:59:58 GMT):
I _think_ it tries to pick a Node.js version that matches the application, and defaults to v4 - I seem to remember having to set something to force it to use v6

sstone1 (Thu, 20 Apr 2017 19:00:40 GMT):
it's possibly these properties we put into our package.json files: ``` "engines": { "node": ">=6", "npm": ">=3" }, ```

jorgedr (Thu, 20 Apr 2017 19:45:10 GMT):
That makes sense, I think the node version that was claiming to be using was 2.x

dkneisly (Thu, 20 Apr 2017 20:22:14 GMT):
@dselman Thank you

tennenjl (Thu, 20 Apr 2017 20:41:23 GMT):
Hi there it appears that we are correctly passing the process.env.COMPOSER_CONFIG into our node app. We also are creating our BusinessNetworkConnection, const BusinessNetworkConnection = require('composer-client').BusinessNetworkConnection; and then in our constructor we set this.bizNetworkConnection = new BusinessNetworkConnection(); When we call the bizNetworkConnection.connect method.. do we then set the arguments such as connectionProfileName and businessNetworkIdentifier to match what is in the COMPOSER_CONFIG env var, I'm not sure what arguments are required and how we point to what we are passing in via COMPOSER_CONFIG. Thanks for any pointers.

@dselman @sstone1 Hi, are there some guidelines regarding the chaincode files organization? Do all dependencies need be resolved by placing all dependent functions in the same file?

No, you are free to organize your files/functions are you wish.

@dselman I tried to make an inheritance hierarchy like bellow and it didn't work till I placed both "BaseType" and "SpecializedType" code in the same file

uber.twin (Fri, 21 Apr 2017 08:28:37 GMT):
``` //base type function BaseType(name) { this.name = name; this.sayName(); } BaseType.prototype = { constructor: BaseType, sayName: function (name) { console.log(this.name); } } //specialized type function SpecializedType(name) { BaseType.call(this, name); } SpecializedType.prototype = Object.create(BaseType.prototype); SpecializedType.prototype.constructor = SpecializedType; SpecializedType.ST1 = new SpecializedType("ST1"); ```

uber.twin (Fri, 21 Apr 2017 08:29:58 GMT):
it was complaining about no such function "sayName()" when running SpecializedType.ST1 = new SpecializedType("ST1");

dselman (Fri, 21 Apr 2017 08:35:06 GMT):
Ah, yes -- that may be. You cannot 'require' one file from another, so the files have to be standalone. @sstone1 do you confirm? I assume all functions are loaded into the execution context.

gauthampamu (Fri, 21 Apr 2017 09:13:04 GMT):
@dselman @sstone1 I have question on participants in the perishable network sample. If we are building a network with 2 Growers, 2 Importers and 2 Shippers, what would be size of the network if you are building the network for v1.0. If we need HA, I would assume we will need 2-3 peers per participant. If we go with the assumption that 2 peers are sufficient. We will need around 12 peers. In that case, we will end up with 12 peers, 12 ca, 36 orderers to setup this network ? Understand this is example but I wanted to understand the relationship of the participant in the network model with actual network. If we are building the network for this business, are going to need peers for each grower that we are going to add to the network or is it possible to have single node in the network for all growers.

dselman (Fri, 21 Apr 2017 09:18:12 GMT):
You should not confuse the participants in the network (farmers etc) with the maintainers of the network. It is very unlikely that each participant would want to run their own peer.

dselman (Fri, 21 Apr 2017 09:18:41 GMT):
As a mental model, think of ISPs and the Internet, vs customers that just use the Internet.

dselman (Fri, 21 Apr 2017 09:19:43 GMT):
The beauty of blockchain/Fabric is that everyone gets to decide how much trust they want to delegate.

gauthampamu (Fri, 21 Apr 2017 09:20:22 GMT):
So in this case, we will need just one maintainer for growers and one for all the importers.

dselman (Fri, 21 Apr 2017 09:20:28 GMT):
In this scenario, perhaps the CO-OP for a large set of farmers run a peer.

gauthampamu (Fri, 21 Apr 2017 09:20:32 GMT):
Are we saying..the same for even shippers

gauthampamu (Fri, 21 Apr 2017 09:20:38 GMT):
ok

dselman (Fri, 21 Apr 2017 09:21:09 GMT):
It's flexible -- it comes down to trust, skills and business model

gauthampamu (Fri, 21 Apr 2017 09:21:47 GMT):
If we are dealing with large shipping corporations, I would assume, we need separate peers for each shipper

dselman (Fri, 21 Apr 2017 09:22:43 GMT):
Probably, yes. If they don't want to trust a central authority and want some independence, at the expense of running (or outsouring) the infra.

dselman (Fri, 21 Apr 2017 09:22:43 GMT):
@tennenjl I don't remember seeing that error specifically but it sounds like a protocol issue -- that is sometimes an indication that you are connecting on the wrong port. E.g. connecting to the event hub or peer or vice-a-versa.

MikeC711 (Fri, 21 Apr 2017 11:08:57 GMT):
Is there a spot to find good query examples. I assume that the query is driven by a transaction (at least normally) and I believe I heard that when you get an object/asset in a query, that it will not have all IsRelatedTo objects resolved so you may have to get them ... but I'm just looking for some simple query examples and I'm struggling to find them. Thanks,

MikeC711 (Fri, 21 Apr 2017 11:31:04 GMT):
Nevermind, I got into the registry methods and found it ... assuming getall and then handling the filtering in the then is best option. If that is correct, I just need to verify that I can indeed return a list of matching assets to the REST caller.

Quick comment on tutorial 2 ... At the point of running npm install to build the bna ... would be good to reference to go into my-network directory. Also (and this could be my Xenial VM going a bit crazy) ... npm install is downloading a lot and appears hung on https:////registry.npmjs.org/composer-runtime (or that's huge). Otherwise, I have to say that it is a good soup to nuts run-thru (will say when npm install finishes if I run into other issues). Would love to see a follow on tutorial 3 with a bit more complexity (imports from multiple name spaces in model, query example returning assets w/some property set, ...).

@jamesv84 There is a hosted version of composer-playground (there is a menu option at the top of the fabric-composer site that takes you there), but this version doesn't support adding connection profiles to it yet to allow you to communicate with running Hyperledger fabrics. However if you want to run against a real hyperledger fabric locally then following the tutorial you have just followed will do exactly that by setting up a real instance of hyperledger fabric on your machine and setting up composer-playground to use it

davidkel (Fri, 21 Apr 2017 17:55:38 GMT):
@mohamoud.egal you need to create a connection profile that targets your bluemix provisioned system and then use an appropriate userid and secret.

sstone1 (Fri, 21 Apr 2017 19:18:56 GMT):
OK - so no. There is a defined set - and the only set - of chaincode functions in the Composer chaincode that get called by the Composer client. You cannot use Composer to call arbitrary chaincode functions.

@jamesv84 no -- Fabric doesn't allow return values from invoke AFAIK.

@tennenjl check you are connecting to the right port -- sounds like you may be connecting to the event hub port or peer.

@dselman @jamesv84 true for v0.6, but for v1.0 we can return data from the chaincode - what are you looking to do?

davidkel (Sat, 22 Apr 2017 07:51:47 GMT):
@tennenjl invalid ELF header means the grpc binary code isn't a valid binary file (at least for your operating system). When you pushed your app on bluemix were there any problems reported when it resolved the node modules for your application ?

I am hoping to supply the rest URL with a name as a parameter and and for it to return a Json object with all the person's information. Is that possible?

davidkel (Sat, 22 Apr 2017 13:00:57 GMT):
@tennenjl when you push to bluemix, bluemix determines you are a node js app via the existence of package.json I think. From there it then needs to determine which nodejs buildpack to use. So it should say what level of node/npm it has chosen. It could be that it's chosen a level which isn't supported by hyperledger fabric node client. Best thing to do would be to be explicit about using node version 6 say 6.9.5 or 6.10.2. I would assume bluemix would use information in package.json to determine that.

tennenjl (Sat, 22 Apr 2017 13:01:57 GMT):
@davidkel Many thanks. I just modified the engines stanza in the manifest.yml and am trying again.

tennenjl (Sat, 22 Apr 2017 13:07:30 GMT):
@davidkel Thanks again, that got me past that error, now on to the next one :-)

Hi, when I run composer network list against my original profile and network, it works fine, but if I run composer network list against a different network and profile (with the appropriate creds), it fails with the message: Certificate has not been signed by a trusted authority. [x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "eca")] I am pointing to the same keyValStore directory and I have tried deleting the entry for one specific user before running the command. Any ideas on what I could be doing wrong? Thanks!

dselman (Sat, 22 Apr 2017 16:21:58 GMT):
@tennenjl did you add a certificate to your profile, as described here: http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service

dselman (Sat, 22 Apr 2017 16:23:32 GMT):
@jamesv84 that would be a content-based query -- which is not supported on HLF v0.6, and is only supported on HLF v1 when using CouchDB as the world-state DB. We have not yet implemented support for complex stories -- that is being tracked under this issue: https://github.com/hyperledger/composer/issues/543

ioctl (Sat, 22 Apr 2017 16:33:38 GMT):
Has joined the channel.

tennenjl (Sat, 22 Apr 2017 17:59:40 GMT):
@dselman Yes, thanks, I did add a cert to the profile. Actually I cut and paste the cert from the working profile. Thanks again for the suggestion.

cbf (Sat, 22 Apr 2017 20:00:10 GMT):
@dselman we should get Composer set up in Gerrit

cbf (Sat, 22 Apr 2017 20:00:18 GMT):
and JIRA if that isn't already the case

sstone1 (Sat, 22 Apr 2017 21:07:16 GMT):
@cbf you can attempt to convince me we should do that at the hackfest 😉

dselman (Sat, 22 Apr 2017 21:18:55 GMT):
@sstone1 I'm hoping that: 1/ you come back with a clear understanding of the requirements. 2/ we can meet those with Git, even if it means some overhead for the maintainers :-)

So I was doing something really silly which I should have realized where I was losing my credentials every time I pushed changes up to Bluemix. Now, I see the proper creds in my /home/vcap/app/.composer-credentials dir, but when I attempt to connect using this.bizNetworkConnection.connect(this.CONNECTION_PROFILE_NAME, this.businessNetworkIdentifier, this.enrollmentId, this.enrollmentSecret), I see the following error in the logs:

Cannot create container for service orderer0: Conflict. The container name "/orderer0" is already in use by container "ef21ee5b13fedb1e885bed0cb041214f12f236915501c158f8c83a2a13134c63". You have to remove (or rename) that container to be able to reuse that name.

If it gives an error then add -f at the end

and docker images doesn't show any image other than fabric docker images

Run 'npm install' inside the `composer-sample-applications-hlfv1` dir and check if there are any errors. Make sure you are using a supported version of Node.

@dselman When I fireup fabric-composer after installing and following the readme on my local machine, I get the following error on the browser Error: Collection with ID '$sysdata' does not exist

sstone1 (Sun, 23 Apr 2017 14:07:18 GMT):
@movee2005 you need to clear your browser local storage, I suspect you've used an old version of `composer-ui` or `composer-playground` before.

sstone1 (Sun, 23 Apr 2017 14:07:54 GMT):
You can either clear all your browsing history/data etc or run `localStorage.clear()` in the JavaScript console

the only cert you have is the CA root cert which probably explains the errors

@davidkel I went to that SO page (http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service) but the page that it links to with info. on userid & secret isn't working (screenshot below). I copied the format & inserted it into my connections file then went to Bluemix to get fill out the variable. I only got membershipServicesURL & other couldn't find where on Bluemix to get peerURL, eventHubURL, keyValStore, certificate, certificatePath. Are these variables supposed to be changed or should I keep them the way I found them on the SO page?

@mohamoud.egal you have to replace values in the connection profile and the user ID/secret with values you get from the Bluemix Console

sstone1 (Sun, 23 Apr 2017 18:23:40 GMT):
This is all documented on the SO page: >>> The hostname and port numbers in the URLs must come from the Bluemix dashboard. I find it easiest to get this information by navigating to "Service Credentials" and viewing the default credentials "Credentials-1"

The SO page explains how you get the peerURL value from the Bluemix page

sstone1 (Sun, 23 Apr 2017 19:06:04 GMT):
And no, the user ID/secret cannot be provided via the connection profile.

mohamoud.egal (Sun, 23 Apr 2017 19:29:40 GMT):
@sstone1 Thanks for your patience I got most of the values correct. However 2 questions: 1) is the membershipServicesURL url the same as the peerURL or the url copied from the Network section of Bluemix (screenshot below)? 2) which part of the https://blockchain-certs.mybluemix.net/us.blockchain.ibm.com.cert is the Certificate value?

sstone1 (Sun, 23 Apr 2017 19:31:25 GMT):
yes - you need the membership services URL, not the peer URL for that property

sstone1 (Sun, 23 Apr 2017 19:31:32 GMT):
it's listed as the `ca` in the service credentials

sstone1 (Sun, 23 Apr 2017 19:31:54 GMT):
and the whole of that file is the value of the `certificate` property

you should get a single line string with `\n` in it

sstone1 (Sun, 23 Apr 2017 19:37:07 GMT):
you can put that in as the value of the `certificate` property

that didn't help

mohamoud.egal (Sun, 23 Apr 2017 20:51:06 GMT):
@sstone1 are you suggesting to use that command instead of just composer-rest-server?

mohamoud.egal (Sun, 23 Apr 2017 21:01:17 GMT):
nvm it worked

How can I erase/delete my biz. network on composer without having to empty local storage?

sstone1 (Mon, 24 Apr 2017 01:04:20 GMT):
there's currently not a button to reset a business network in the new playground

sstone1 (Mon, 24 Apr 2017 01:04:54 GMT):
@EdMoffatt that ^ keeps coming up (not being able to easily clear the data in the playground)

MikeC711 (Mon, 24 Apr 2017 01:42:01 GMT):
Quick Q (likely dumb Q) on npm install (from tutorial 2). The npm install would appear to be all about setting up a runnable nodeJS environment presumably for the Embedded runtime. Is this purely for unit tests? Probably worth it either way, but are there other common uses for the Embedded runtime or any other benefits of the npm install? Thanks,

sstone1 (Mon, 24 Apr 2017 01:57:30 GMT):
@MikeC711 it does install the embedded runtime for the unit tests, and also installs mocha/chai (test framework), eslint (checking code for possible errors), jsdoc (generating docs), and license-check (validating license headers)

sstone1 (Mon, 24 Apr 2017 01:58:18 GMT):
the embedded runtime is primarily for testing; we've looked at unit testing using something like mocha, and also BDD testing using cucumber

sstone1 (Mon, 24 Apr 2017 01:59:41 GMT):
it could also be integrated into an editor (such as atom or vscode), and used to develop/test a business network definition in the same way as the playground uses the web runtime

how do we add to composer-credentials ?

karthikworks (Mon, 24 Apr 2017 07:26:51 GMT):
I think the folder is empty..

sstone1 (Mon, 24 Apr 2017 07:55:42 GMT):
@karthikworks files get added to that folder when you enroll (login). those files contain your enrollment certificates (public/private keys).

sstone1 (Mon, 24 Apr 2017 07:56:21 GMT):
when you use the commands or APIs with an ID that you haven't yet enrolled with, then we call enroll and ask membership services for an enrollment certificate.

sstone1 (Mon, 24 Apr 2017 07:56:41 GMT):
if you don't give it a valid ID/secret, or if the secret has been used before, then enrollment fails and you don't get a file in that directory.

karthikworks (Mon, 24 Apr 2017 09:05:21 GMT):
Solved it..

what was the solution?

karthikworks (Mon, 24 Apr 2017 10:12:34 GMT):
On the connection profile file the networks were listed as blank, once i deleted it and tried again.. the member. got generated and worked...

karthikworks (Mon, 24 Apr 2017 10:12:54 GMT):
Now i have another issue.. i think after the update it has started..

this happens on yo fabric-composer

1 more quick questions per tutorial 2 ... In Commodity ... if it has been o Trader owner instead of --> Trader Owner (I know, wouldn't make sense, but work w/me) ... would it then have been an simple assignment of my ref to owner instead of a factory.newRelationship Thanks,

Good morning guys, I have a question regarding the composer-client library. Basically we have a REST API server that will the one responsible to talk to a Fabric instance when requests come in. In such scenario we could have multiple requests coming at the same time and being routed to the same REST API server instance. So my question is, is the composer-client library stateless so that I can handle multiple requests simultaneously?

@vinitesh The connection profile isn't correct. For HLF V1 alpha and TLS Support its as follows :- ``` { type: 'hlfv1', orderers: [ { url: 'grpcs://localhost:7050', cert: '' } ], ca: 'https://localhost:7054', peers: [ { requestURL: 'grpcs://localhost:7051', eventURL: 'grpcs://localhost:7053', cert: '' }, { requestURL: 'grpcs://localhost:7056', eventURL: 'grpcs://localhost:7058', cert: '' } ], keyValStore: '/.hfc-key-store, channel: '', mspID: '', deployWaitTime: '300', invokeWaitTime: '100' } ``` Make sure you chose a ca that is associated with your peers (ie has the same MSPId as your peers)

vinitesh (Mon, 24 Apr 2017 16:26:13 GMT):
thanks @davidkel In my network i am having 2 members so total 4 peers and CAs , 2 for each member and 2 msid group PeerOrg1 and PeerOrg2. Now if i want to deploy the .bna to all peers then how can i give details of multiple ca in the connection file

vinitesh (Mon, 24 Apr 2017 16:26:40 GMT):
or i should deploy the .bna seperately for each member?

davidkel (Mon, 24 Apr 2017 16:28:37 GMT):
@vinitesh I would suggesting trying to deploy to each organisation separately.

davidkel (Mon, 24 Apr 2017 16:28:37 GMT):

@vinitesh but then interacting with that could be a problem

davidkel (Mon, 24 Apr 2017 16:31:38 GMT):
@vinitesh but then interacting with that could be a problem. I'm thinking about the endorsement policy for example if you need to get at least 1 peer from each organisation to endorse then you need to be able to send requests to all the peers in the channel

vinitesh (Mon, 24 Apr 2017 16:33:03 GMT):
thanks @davidkel , So in 1 org i have 2 peers and 2 ca , do i need to mention both ca in the connection file

vinitesh (Mon, 24 Apr 2017 16:36:31 GMT):
or its just there for failover recovery

vinitesh (Mon, 24 Apr 2017 16:36:31 GMT):
or its just there for failover recovery?

davidkel (Mon, 24 Apr 2017 16:37:23 GMT):
You only need to define 1 ca in the connection profile. We don't support any type of failover capability

vinitesh (Mon, 24 Apr 2017 17:07:40 GMT):
Thanks @davidkel for the help .Now i deployed .bna network into the bluemix. Should i be able to see the generic chaincode for composer in the chaincode section of blockchain service?

davidkel (Mon, 24 Apr 2017 17:10:49 GMT):
@vinitesh can you do a network ping ? if you can then composer runtime is running. If you can't see something you expect to see in the bluemix interface and you can interact with your business network ok then I suggest contacting bluemix about it

vinitesh (Mon, 24 Apr 2017 17:50:17 GMT):

@vinitesh fyi...there was the following problem awhile ago, https://github.ibm.com/IBM-Blockchain/ui-development/issues/496 so you might run into that

vinitesh (Mon, 24 Apr 2017 18:12:05 GMT):
Hello, In my transaction processor function i am creating and adding a new asset to asset registry . For each asset i need generate a unique id . how to generate this unique id so that the code doesn't become non deterministic as the same code will run on multiple peers

dselman (Mon, 24 Apr 2017 18:13:09 GMT):
you could use the transactionID property of the transaction, or you pass it in on the transaction as a property.

MikeC711 (Mon, 24 Apr 2017 18:13:34 GMT):
Woops, this is a continuation... and if I delay the start (to 85 seconds in this case), and attach to the container, I see: root@b7fce2597421:/opt/gopath/src/github.com/hyperledger/fabric# nc membersrvc 7054 nc: getaddrinfo: Name or service not known So it looks like when I had the wrong docker-compose ... because somehow the membersrvc link is not working in peer. What is odd is that it was running a short time ago when I was using it for the playground. It was in tutorial 2 when I tried deploying my bna into this sample network. Not sure if it died just before that, or after. Well, now that I look at it ... it looks like my localhost:8080 is working fine even though there is no peer. I can only imagine that it is not using a peer since the peer container crashes and burns, not finding membersrvc

vinitesh (Mon, 24 Apr 2017 18:19:44 GMT):
@jdockter i am not able to reach the link as it requires ibm id can you please share the context

@dselman I've been playing with your suggestion about modifying transactions, and it seems like altering the transaction object within a transaction callback handler has no effect on the data persisted to the network. So as yet I still can't see a way to dynamically inject extra system attributes into a transaction payload at runtime. Any pointers for me?

vinitesh (Tue, 25 Apr 2017 08:10:22 GMT):
Hello, I have setup a blockchain service on bluemix , It has 3 members Initiator,provider and service partner . i have also deployed my network .bna to the blockchain. in my network i have also defined same 3 participants Initiator,provider and service partner, Now how do i link the blockchain member to the network participants. Do i need to explicitily create a participant for each member and issue them identity?

dselman (Tue, 25 Apr 2017 08:17:29 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=vpKqzTfQvPzc8Tuha) @pospi that makes sense I think. The transaction persisted into the transaction registry will be as received by the runtime. You can modify the transaction within your tx processor functions (it is just a JS Object) but that won't have any effect on the transaction registry. I don't think it makes sense to modify the transaction in Fabric terms in the chaincode, as it will be distributed to all peers for processing. Can you not make these modifications on the client? What are you trying to do?

davidkel (Tue, 25 Apr 2017 08:18:12 GMT):
@vinitesh You would create your participants in your business network then use the composer identity issue to create identities which you can then use to drive transactions and perform acl checks. However it is highly likely that the identity issue will fail at the moment but you could try

dselman (Tue, 25 Apr 2017 08:18:35 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=DdRc2eZqjFRmGvyq8) @vinitesh short answer is yes. Long answer is don't (necessarily) conflate a Fabric member (maintainer of the network, holds a copy of the distributed ledger) with a participant in a business network (could be an end user).

pospi (Tue, 25 Apr 2017 08:24:02 GMT):
@dselman end goal is to setup a bidirectional link between an asset and a set of transactions such that looking up one from the other in both directions is achievable. I need these assignments to be as opaque as possible to the consumer, so I'm trying to get it all to be driven by transaction execution logic.

vinitesh (Tue, 25 Apr 2017 08:28:20 GMT):
thanks @davidkel . I have tried issue identity on bluemix blockchain v1 beta and its working fine, It returned a secret and i am able to ping the network with new identity. thumbs up for this:)

davidkel (Tue, 25 Apr 2017 08:41:50 GMT):
@vinitesh thanks for the update on that, guess bluemix haven't changed the organisation structure from the default fabric-ca setup yet which is why it works.

Hi I find that the docs about the fabric composer are about fabric V.06, but now I am using fabric V1.0

https://fabric-composer.github.io/tutorials/getting-started-playground.html

xuzhao103389 (Tue, 25 Apr 2017 09:42:36 GMT):
so is there any new docs about fabric 1.0?

vinitesh (Tue, 25 Apr 2017 09:56:24 GMT):
thanks @dselman it means its not neccessary to define the participants of my network as the members of blockchain service. But if we want to create channel between the participants for data seperation then we may create participant as members of network just to keep it logical.

xuzhao103389 (Tue, 25 Apr 2017 10:08:13 GMT):
@vinitesh Hi can you give me some instructions that how to use fabric composer for fabric V1.0 ?

davidkel (Tue, 25 Apr 2017 10:14:00 GMT):
@xuzhao103389 it's currently not possible to use composer-playground to directly interact with a fabric v1.0 alpha yet (it's being worked on) however you should be able to export your business network archive from composer-playground and then use the composer cli to deploy to a fabric 1.0.

yep it creates TypeScript Definition files that mainly make it a bit easier to develop on Playground

sstone1 (Tue, 25 Apr 2017 11:41:02 GMT):
all of the relevant `package.json` files have `"typings": "index.d.ts",` so they should be usable elsewhere

maybe i should pull it out into a separate npm module external to composer

MikeC711 (Tue, 25 Apr 2017 13:10:39 GMT):
No resolution yet to my issue. I was going thru tutorial2 from Dan and all was going well with the Embedded runtime. I then tried starting my network (local docker containers thru the docker-compose.yml) ... and I am back to the scenario where the peer container no longer sees membersrvc as a host .. which is similar to the docker-compose issue I had when I was on the pip installed docker-compose 1.12.xxx. My docker-compose is still good: docker -v && docker-compose -v && node -v && npm -v Docker version 17.04.0-ce, build 4845c56 docker-compose version 1.11.2, build dfed245 v6.10.1 4.4.4 I am wondering if the node container for the Embedded runtime is still up, but a ps -ef | grep -i node (w/and w/out sudo) just shows the vscode processes (/usr/share/code/code) and the grep itself (assuming I shut down the other 2 containers. Interestingly though, if I bring up the containers (membersrvc and playground webapp stay up) ... the playground works great. Nobody is listening on any of the 70 ports when the containers are down (just 7054 when I start them and peer shuts down) ... but the playground (localhost:8080) works great. I thought it might be using browser memory, but I stopped and re-started the browser and the assets and participants were still there. So maybe this is tied to the Composer embedded runtime being up and I can't seem to find it? Any thoughts?

sstone1 (Tue, 25 Apr 2017 13:19:13 GMT):
@uber.twin no idea I'm afraid

sstone1 (Tue, 25 Apr 2017 13:19:59 GMT):
From that blog post, it seems they could be using any of the Hyperledger projects

uber.twin (Tue, 25 Apr 2017 13:21:25 GMT):
yes, but the Hyperledger link in there goes to "IBM launches blockchain ecosystem on Hyperledger Fabric"

MikeC711 (Tue, 25 Apr 2017 13:33:25 GMT):
@MikeC711 Tied to that, I shut down the browser and went to my host (Xenial is a KVM guest) and hit the URL via IP ... and was told that I needed to clear memory as it was a different version of Composer. So maybe the playground webapp container was indeed using the browser. I guess I'm back to figuring out why I can't see membersrvc in the peer.

any idea on why this happens ?

karthikworks (Wed, 26 Apr 2017 06:38:42 GMT):
Agreement & Internal are transactions

dselman (Wed, 26 Apr 2017 07:19:58 GMT):
@kouohhashi the arguments to `composer network undeploy` are wrong: ```composer network undeploy [options] Options: --help Show help [boolean] -v, --version Show version number [boolean] --businessNetworkName, -n The business network name [string] [required] --connectionProfileName, -p The connection profile name [string] --enrollId, -i The enrollment ID of the user [string] [required] --enrollSecret, -s The enrollment secret of the user [string] ```

dselman (Wed, 26 Apr 2017 07:21:21 GMT):
@karthikworks are the types `abstract`? I think we may have a bug in that abstract types are not exposed over REST, but if they are used as arguments to other methods you see this. I've not had time to diagnose fully however so would appreciate help.

dselman (Wed, 26 Apr 2017 07:23:03 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=s9dEoMmhAfGEXG2rD) @pospi No, we do not support this. I think adding this open a can of worms in terms of object model evolution and understanding the structure of the data on the blockchain. Using abstract types and class inheritance is better IMO.

karthikworks (Wed, 26 Apr 2017 07:35:49 GMT):
@dselman they are not abstract types. Both are transactions, will check little deep and get back.

karthikworks (Wed, 26 Apr 2017 07:36:51 GMT):
Any idea on how can i add participants and transactions to the Angular application - it does not get added to the skeleton but how do i do it manually ?

karthikworks (Wed, 26 Apr 2017 07:37:27 GMT):
When i tried to add manually, it throws an error "not a module"

pospi (Wed, 26 Apr 2017 08:46:30 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=CZit6rss2WRCe2BBZ) @dselman completely agree, but as yet I've been unable to get those features working so am investigating workarounds for polymorphism. or can I try https://github.com/hyperledger/composer/pull/720 in the latest release?

As per my understanding I need to have a connection profile and provide Hyper Ledger URL in it. Where can I configure Connection profile? (If it is not supported in Fabric Composer 0.5.10 version is there any earlier version available ? example that someone can share? Thanks.

Hi,

SahilKapoor (Wed, 26 Apr 2017 12:26:39 GMT):
I was able to run fabric composer example as mentioned in the documents. I have doubt regarding which version of fabric is running.

SahilKapoor (Wed, 26 Apr 2017 12:26:53 GMT):
The console says: Status: Downloaded newer image for hyperledger/fabric-baseimage:x86_64-0.1.0 docker tag hyperledger/fabric-baseimage:x86_64-0.1.0 hyperledger/fabric-baseimage:latest

SahilKapoor (Wed, 26 Apr 2017 12:27:19 GMT):
which says base image from fabric 1.0.

SahilKapoor (Wed, 26 Apr 2017 12:27:42 GMT):
Is there a command to check which version of fabric is running?

dselman (Wed, 26 Apr 2017 12:36:28 GMT):
If you run `docker ps -a` you can tell from the containers.

SahilKapoor (Wed, 26 Apr 2017 13:13:43 GMT):
There is no order service , only a member service and peer. I think couple of days back the git on the https://fabric-composer.github.io/installing/quickstart.html mentioned 1.0 and 0.6 but today it just mentions one git repo which i think is based on 0.6. Are there any docs for fabric composer 1.0 .

MikeC711 (Wed, 26 Apr 2017 14:37:32 GMT):
@dselman Sure Dan, I was going back thru tutorial 2 (your code this time, my code next time). I hit a brick wall on the deploy command thru the CLI which turned out to be tied to a docker/docker-compose issue and RHEL/CentOS (My Xenial system is a KVM guest of an RHEL host). Now that I finally got thru that, I tried doing the deploy again. I verified that the containers were up and could see each other ... but my deploy failed with the messages shown. I verified that the connect.json in defaultprofile looks correct and it certainly did not complain about that. I then brought up my localhost:8080 (webapp in my local docker container) ... and it seems that he's using browser memory and not the membersrvc and vp0 that I thought he would. He had me clear the cache right away (forget the message) ... this makes me think he is looking at the browser and not the containers. As it is, I had no problem importing my bna ... but obviously I'm looking to develop procedures where-by I use the cli or whatever is the preferred mechanism) to do deploys et al. Thanks,

@MikeC711 Playground only uses browser local storage today -- if you want to connect from the web interface to a real Fabric you have to use the "old" Composer-UI

Or you can develop inside Playground, export your BNA file and then use the composer CLI to deploy the BNA.

jorgedr (Wed, 26 Apr 2017 16:01:18 GMT):
Hey guys, I have noticed that several of the `models` directories under each of the composer-sample-networks repos are gone. For example `composer-sample-networks/packages/digitalproperty-network/models` is not there also `composer-sample-networks/packages/animaltracking-network/models` is not there.

jorgedr (Wed, 26 Apr 2017 16:02:13 GMT):
The `basic-sample-network` does have the models directory under it.

dselman (Wed, 26 Apr 2017 16:10:20 GMT):
This is because those networks use an npm dependency to their models. I.e. package.json for the network depends on an npm package for the models.

dselman (Wed, 26 Apr 2017 16:10:49 GMT):
This allows the models to be semantically versioned and published independent of the network. Reuse of models across network! :-)

jorgedr (Wed, 26 Apr 2017 16:14:34 GMT):
That is cool @dselman and I think I understand the flexibility to have a model described by a package and getting npm to install it. Having said that. I am talking about the actual repo where the models reside https://github.com/hyperledger/composer-sample-networks . I believe this is the repo where you guys keep sample networks , under packages you can see several sample models, one of them let's say animaltracking-network . That directory has the transactions under the lib directory but the models directory is missing.

dselman (Wed, 26 Apr 2017 16:15:26 GMT):
Dependent models are resolved from the `composer-sample-models` repor

DennisM330 (Wed, 26 Apr 2017 17:55:16 GMT):
In the older composer-ui, I could switch networks and it would allow me to connect to a business network on the blockchain. the composer playground does not allow you to do so. However, the user interface in the playground states this and says you can install a local playground. Everything I have installed is local and I assumed is it referring to use use the docker-compose run -d command? However, when I did that I see the same notation in the playground. Is there some other alternative to the installation that I need to perform?

DennisM330 (Wed, 26 Apr 2017 18:15:48 GMT):
Ah, I see from earlier posts that the connections capability is not yet available in the playground - local install

jinvanstee (Wed, 26 Apr 2017 18:27:10 GMT):
@DennisM330 sounds like they are hoping to publish the composer playground with connection capability by end of this week

I tested my network successfully in the composer-playground. All transactions worked as expected. I exported the bna file, deployed to running Fabric, and then tried to test a transaction with the composer-rest-server. Transactions just timeout with a 500 error. Any idea on where to look for root cause? When I test with loopback composer-rest-server, I remove transaction ID from the POST as it does not want that value set

DennisM330 (Wed, 26 Apr 2017 21:13:45 GMT):
I can create assets and participants just fine with the loopback composer-rest-server though

davidkel (Wed, 26 Apr 2017 21:13:46 GMT):
@Dpkkmr One of the issues with hyperledger fabric 0.6 is that failures couldn't be returned to the client. Because of this a timeout is needed. This is something that is addressed in the upcoming hyperledger fabric 1.0. So it is likely that it wasn't something taking too long but a failure. The only way to determine what the failure might be would be to look at the logs of the various fabric services and chaincode service to see if they provide any further information. There is more info in the SO entry http://stackoverflow.com/questions/42695751/how-do-i-see-the-logs-for-fabric-composer which heopfully will help in getting log information from the runtime

davidkel (Wed, 26 Apr 2017 21:15:51 GMT):
@DennisM330 If your transactions are timing out, then it could be a problem in your transaction code (I assume you are using hyperledger fabric 0.6 ?) Worth checking the chaincode container logs to see if there are any errors. See the SO entry http://stackoverflow.com/questions/42695751/how-do-i-see-the-logs-for-fabric-composer which heopfully will help in getting log information from the runtime

DennisM330 (Wed, 26 Apr 2017 21:46:33 GMT):
Yep, just saw the first posting, now I remember that v0.6 does not return the error and instead returns a timeout

DennisM330 (Wed, 26 Apr 2017 23:13:03 GMT):
@dselman Thanks Dan, found my issue tonight. Two of my assets each had an array that referenced another asset. I did not mark the array as optional when I should of. The playground lets you test and create assets and I could specify an empty array. In the composer rest server, I cannot when creating an asset and it was creating an array element with a value of "string". So I corrected my definition in the playground and marked as optional. Apparently the chaincode in the blockchain validates the element in the array that it exists

The final error goes away, but I still get: composer network deploy -a dist/my-network.bna -i admin -s Xurw3yU9zI0l Deploying business network from archive: dist/my-network.bna Business network definition: Identifier: my-network@0.0.1 Description: My first fabric composer network TypeError: Cannot read property 'fail' of undefined Command failed and I can't find "fail" in any js, cto, acl, or anything else (outside of node-modules). I "think" I've been doing it all correctly as I have been cutting and pasting. Will bring my app up to date and will see if the error is still there. The app deploys into the playground painlessly and I can create participants, assets,and trans ... I imagine that the deploy is not terribly different than importing into the playground. Thanks again for finding that fat-finger. Not sure where I copied that from, but clearly I missed that detail.

I thought that installing playground locally either via npm or docker would allow access to a local fabric?

abcoathup (Thu, 27 Apr 2017 02:31:56 GMT):
"sudo npm install -g composer-playground" fails on "npm http 404 https://registry.npmjs.org/ng-bootstrap/ng-bootstrap"

@kouohhashi It would seem to me that the containers are being recreated when you restart them (rather than being stopped at shutdown and started up again). In that case then I would fully expect you to have to create the channel and join the peers to the channel because you have effectively created a whole new fabric environment.

davidkel (Thu, 27 Apr 2017 07:25:44 GMT):
@MikeC711 I suggest you upgrade your level of composer. The error you see is a bug in composer that has been fixed but unfortunately it hides the real error message of what the problem is

dselman (Thu, 27 Apr 2017 07:49:49 GMT):

Hi guys. Anybody tried to use authentication with composer-rest-api. Can't get my head around it. How do I create a username/password and then do authentication?

dselman (Thu, 27 Apr 2017 08:21:48 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-composer?msg=HAfP2HfphSwQtgKdj) @GeorgSchultz there's no reset button (yet). You can open the Javascript console and type `localStorage.clear()`

dselman (Thu, 27 Apr 2017 08:21:57 GMT):
then refresh

nvlasov (Thu, 27 Apr 2017 08:56:24 GMT):
Ok, to be more specific, here are the questions: 1. How can I create a new user account with username/password to authenticate against composer-rest-server? 2. How would I authenticate with this newly created user account against composer-rest-server? 3. How would I manage the session for that user? 4. How can I map this user to a network participant? 5. Can composer-rest-server user be mapped to more then one network participant (i.e. perform different roles)? 6. Do I need to create a wallet for each composer-rest-server user? 7. How would I share wallets across number of instances of composer-rest-server?

nvlasov (Thu, 27 Apr 2017 09:09:05 GMT):
Also, for composer-rest-server: can I exclude some operations from exposed API? I.e. I don't want to allow anybody ever delete an asset. Can I completely remove DELETE operation for my asset?

I'll work with @sstone1 to get answers

@MikeC711 the other two I find myself updating, IF you use them, would be the rest server and generator, so `npm install -g composer-rest-server` and 'npm install -g generator-fabric-composer'

Not sure if anyone else ran into this, but when I do an export from the playground on my Mac, the filename is named unknown and it is a filetype of textedit document. I just rename the file as appropriate for my network and add a .bna filetype

davidkel (Thu, 27 Apr 2017 15:25:13 GMT):
@MikeC711 it could be an issue with credentials. I would recommend deleting the contents of your keyValStore (/home/mcasile/.composer-credentials) and start new hlf v0.6 containers. Reason is that when you enroll an ecert is stored in your keystore. If you start new containers then the previous stored ecerts won't be valid, you need a new ecert but as one already exists composer uses it.

DennisM330 (Thu, 27 Apr 2017 16:07:03 GMT):

dselman (Thu, 27 Apr 2017 16:25:22 GMT):
@DennisM330 we do not yet support complex (content-based) queries. The REST API only allows you to retrieve assets/participants by id.

DennisM330 (Thu, 27 Apr 2017 17:01:58 GMT):
@dselman - Thanks for the clarification. I was wondering if you could do that, having worked with Loopback myself four a couple of years, I remember using filters and creating relationships

davidkel (Thu, 27 Apr 2017 18:36:43 GMT):
@kouohhashi in that scenario the containers are stopped and restarted so the information they have remains but it looks like the chaincode containers are not restarted. It would be worth you asking the question about that on perhaps the #fabric-questions (not sure if that would be the right place but hopefully someone can suggest a better channel if not). This sounds in the first instance like something HLF should handle

jorgedr (Thu, 27 Apr 2017 20:58:38 GMT):
Hey guys, quick question, let's say I have an asset into multiple registries and I make an update to the asset, Do I have to call the `update` method on each registry for the changes to reflect on each of them or by calling it just in one will spread out in all the other registries.

sstone1 (Thu, 27 Apr 2017 21:01:04 GMT):
@jorgedr you will have to update the asset in all registries independently

jorgedr (Thu, 27 Apr 2017 21:04:51 GMT):
oh.. interesting.. @sstone1 that kind of breaks down my understanding of what a registry is. I thought that a registry was just pointing to an instance of an object so that if you update the object all other registries would see the update. Does that mean that each registry has its own instance of the object? I am kind of confused as to why updating

sstone1 (Thu, 27 Apr 2017 21:05:40 GMT):
Yeah, each registry has its own instance of the object.

sstone1 (Thu, 27 Apr 2017 21:05:55 GMT):
Are you using custom registries using `addAssetRegistry`?

jorgedr (Thu, 27 Apr 2017 21:06:32 GMT):
Correct, we wanted to move the asset from registry to registry as it went through its lifecycle

jorgedr (Thu, 27 Apr 2017 21:19:07 GMT):
wondering if a better approach would be to create an "asset" that all it would have is a reference to the actual asset i.e. ``` asset MyAssetRef identified by id { o String id --> MyAsset asset } ``` And then just put the asset reference in as many registries as we want. The advantage being here that I am not creating multiple instances of a possibly big object but just a very simple instance that just have a pointer.

sstone1 (Thu, 27 Apr 2017 21:31:56 GMT):
that would work

sstone1 (Thu, 27 Apr 2017 21:32:05 GMT):
we have not done a lot of work for custom registries yet

sstone1 (Thu, 27 Apr 2017 21:32:10 GMT):
a lot of functionality does not work yet

sstone1 (Thu, 27 Apr 2017 21:32:19 GMT):
such as relationships to assets/participants in custom registries

sstone1 (Thu, 27 Apr 2017 21:33:04 GMT):
@nvlasov I've answered the Stack Overflow question http://stackoverflow.com/questions/43655553/how-to-authenticate-to-rest-api-and-map-to-fabric-credentials/43668254#43668254, and pointed you to the work in-progress GitHub issue https://github.com/hyperledger/composer/issues/142 :)

jorgedr (Thu, 27 Apr 2017 21:34:08 GMT):
so just so I understand, if I create a custom registry and I call the resolve method on it, it would not resolve that relationship

jorgedr (Thu, 27 Apr 2017 21:35:20 GMT):
I would have to get the reference then get the identifier from the reference and go to the main registry for the asset and load it from there?

jorgedr (Thu, 27 Apr 2017 21:35:56 GMT):
I think that is what you kind of said :smile:

sstone1 (Thu, 27 Apr 2017 21:36:07 GMT):
if you create a relationship to an asset that is in a custom registry, then we cannot resolve that relationship.

sstone1 (Thu, 27 Apr 2017 21:36:17 GMT):
we can only resolve relationships to assets that are in their default registry.

Quick Q on junit scripts (which could tie back to others later), can a registry be saved and re-used? I ask because in test/Sample.js in tutorial2 ... they appear to have the assetRegistry at the beginning, but then they retrieve it again when they want to get the asset back out of the registry (after a tran). Could they have just used the reference that they already had ... or is there something particularly volatile about assetRegistry (or participantRegistry for that matter)? Thanks,

const mortgage1 = factory.newResource(NS, 'MortgageApplication', 'mortgageApp1'); mortgage1.client = factory.newRelationship(NS, 'BankCustomer', mike.$identifier) ; mortgage1.bankInfo = [] ; mortgage1.bankInfo[0] = { name : 'MikeBank', routingNumber : 123456, accountNumber : 654321, accountType : 'Checking', balance : 12345.67 } ; mortgage1.applicationStatus = 'Applied' ; Error in running test: 1) Mortgage Work #tradeCommodity should be able to trade a commodity: ValidationException: Model violation in instance com.ibm.sample.mortgage.MortgageApplication#mortgageApp1 class com.ibm.sample.mortgage.BankInfo has value [object Object] expected a Resource or a Concept. at Function.reportNotResouceViolation (node_modules/composer-common/lib/serializer/resourcevalidator.js:448:15) at ResourceValidator.visitClassDeclaration (node_modules/composer-common/lib/serializer/resourcevalidator.js:113:31) at ResourceValidator.visit (node_modules/composer-common/lib/serializer/resourcevalidator.js:64:25) at ConceptDeclaration.accept (node_modules/composer-common/lib/introspect/classdeclaration.js:63:24) at ResourceValidator.checkItem (node_modules/composer-common/lib/serializer/resourcevalidator.js:335:30) at ResourceValidator.checkArray (node_modules/composer-common/lib/serializer/resourcevalidator.js:262:18) at ResourceValidator.visitField (node_modules/composer-common/lib/serializer/resourcevalidator.js:208:22) at ResourceValidator.visit (node_modules/composer-common/lib/serializer/resourcevalidator.js:68:25) at Field.accept (node_modules/composer-common/lib/introspect/property.js:48:24) at ResourceValidator.visitClassDeclaration (node_modules/composer-common/lib/serializer/resourcevalidator.js:164:26) at ResourceValidator.visit (node_modules/composer-common/lib/serializer/resourcevalidator.js:64:25) at AssetDeclaration.accept (node_modules/composer-common/lib/introspect/classdeclaration.js:63:24) at Serializer.toJSON (node_modules/composer-common/lib/serializer.js:87:30) at AssetRegistry.add (node_modules/composer-client/lib/registry.js:194:50) at businessNetworkConnection.getAssetRegistry.then (test/Sample.js:137:38) Makes me think I'm wrong about how to handle that array. I got the same error when I tried: mortgage1.bankInfo = [{ name : 'MikeBank', routingNumber : 123456, accountNumber : 654321, accountType : 'Checking', balance : 12345.67 } ] ; So not exactly sure how to handle an array of a concept (or so it seems).

dselman (Fri, 28 Apr 2017 06:32:17 GMT):
@MikeC711 you have to use factory.newConcept to create an instance of a concept.

conroydave (Fri, 28 Apr 2017 06:56:11 GMT):
Hi Dan. do you have a link to the sample he is trying to run, with mortgages?

dselman (Fri, 28 Apr 2017 07:16:29 GMT):
No, that is something @MikeC711 is building I think.

conroydave (Fri, 28 Apr 2017 07:18:55 GMT):
ah ok. his namespace made me think it was some IBM app "com.ibm.sample.mortgage.MortgageApplication#mortgageApp1 "

I have a query about the .bna file

xuzhao103389 (Fri, 28 Apr 2017 11:00:24 GMT):
in the example

xuzhao103389 (Fri, 28 Apr 2017 11:01:11 GMT):
the model is : namespace net.biz.digitalPropertyNetwork asset LandTitle identified by titleId { o String titleId --> Person owner o String information o Boolean forSale optional } asset SalesAgreement identified by salesId { o String salesId --> Person buyer --> Person seller --> LandTitle title } participant Person identified by personId { o String personId o String firstName o String lastName } transaction RegisterPropertyForSale identified by transactionId{ o String transactionId --> Person seller --> LandTitle title }

xuzhao103389 (Fri, 28 Apr 2017 11:01:31 GMT):
and the operation is

xuzhao103389 (Fri, 28 Apr 2017 11:01:32 GMT):
function onRegisterPropertyForSale(propertyForSale) { console.log('### onRegisterPropertyForSale ' + propertyForSale.toString()); propertyForSale.title.forSale = true; /* new line is here to update the information */ propertyForSale.title.information = propertyForSale.title.information + ' Updated at: ' + new Date().toDateString(); return getAssetRegistry('net.biz.digitalPropertyNetwork.LandTitle').then(function(result) { return result.update(propertyForSale.title); } ); }

xuzhao103389 (Fri, 28 Apr 2017 11:02:27 GMT):
so who can tell me how to link the method onRegisterPropertyForSale(propertyForSale) with the transaction defined as "transaction RegisterPropertyForSale identified by transactionId"

xuzhao103389 (Fri, 28 Apr 2017 11:05:03 GMT):
so why 'onregisteryPropertyForSale' is the implementation of the `registeryPropertyForSale` transaction

xuzhao103389 (Fri, 28 Apr 2017 11:05:04 GMT):
?

xuzhao103389 (Fri, 28 Apr 2017 11:05:25 GMT):
and can I add some more parameters to onRegisterPropertyForSale(propertyForSale) ?

Jakeeyturner (Fri, 28 Apr 2017 11:15:46 GMT):
The javascript transaction processor function is linked to a modeled transaction by a `@param` tag

MikeC711 (Fri, 28 Apr 2017 11:59:30 GMT):
@dselman Thanks Dan, I'll make that change. Also trying to re-structure a bit to avoid multiple tests inside one construct (so failures are hard to diagnose).

xuzhao103389 (Fri, 28 Apr 2017 12:16:03 GMT):
@Jakeeyturner can you show me the details about it thanks :)

Hello, does anyone know if it is possible with composer playground v0.5.12 running locally to add a connection profile to be able to connect it to my local fabric server?

Jakeeyturner (Fri, 28 Apr 2017 13:30:50 GMT):
@DanHerman Not at the moment, it's currently being worked on (as well as identity support).

DanHerman (Fri, 28 Apr 2017 13:32:38 GMT):
@Jakeeyturner Thanks, good to know. One more question, is there a way to get a transaction list from the composer-rest-server, or is the only way to get transactions direct from the fabric server?

MikeC711 (Fri, 28 Apr 2017 14:24:17 GMT):
@conroydave Yes, this is an effort on the part of the Competitive Project Office to take a soup to nuts look at HLF and HFC vs Ethereum from the aspect of a developer learning it, developing it, etc.. We chose a mortgage application process and I wrote the first iteration as standalone silo applications (all in nodeJS w/Cloudant) from the bank, the credit agency, the municipality, ... and now I am doing the inclusion of Blockchain hlf/hfc as a colleague is doing it from the Ethereum perspective. Just to put context to my constant pestering of the SMEs.

annbnn (Fri, 28 Apr 2017 14:33:04 GMT):
@Jakeeyturner I have a philosophical question :-) If you had to create a decentralized marketplace for digital currencies, why would you choose hyperledger fabric ?

@annbnn that's a great question to ask in #fabric or #fabric-questions

MikeC711 (Fri, 28 Apr 2017 14:35:00 GMT):
One quick unit test question ... in tutorial 2 ... much of the unit test functionality is of the form: then(() => { return ... But as I'm trying to get familiar with mocha and chai, I see https://mochajs.org/#arrow-functions which discourages arrow function for their loss of mocha context. Coming in from a point of complete ignorance ... is this a stylistic thing ... or am I missing something. Is there a notable benefit to arrow function (lamdas) over defined functions?

Possible doc error? At https://hyperledger.github.io/composer/jsdoc/module-composer-runtime.Factory.html it shows: newConcept(ns, type) ... but the sample just below it shows: var record = factory.newConcept('org.acme', 'Record', 'RECORD_1'); I think 3rd parm doesn't belong unless concept is just a string. Also possible I'm mis-understanding.

MikeC711 (Fri, 28 Apr 2017 18:41:09 GMT):
On a concept ... this looks a bit verbose ... am I missing something to short-hand it? let bankInfoConcept = factory.newConcept(NS, 'BankInfo') ; bankInfoConcept.name = 'MikeBank' ; bankInfoConcept.routingNumber = 123456 ; bankInfoConcept.accountNumber = 654321 ; bankInfoConcept.accountType = 'Checking' ; bankInfoConcept.balance = 12345.67 ; assets.mortgage1.bankInfo = [] ; assets.mortgage1.bankInfo.push(bankInfoConcept) ; Would love to be able to do bankInfoConcept = { name : 'MikeBank', routingNumber : 123456, ... } ; Possibly feed that in to the newConcept method ? I'm at best intermediate on js specific skills ... so maybe I'm missing something from javaScript to simplify this.

sstone1 (Fri, 28 Apr 2017 19:04:08 GMT):
@MikeC711 you could try using Object.assign: ``` let bankInfoConcept = factory.newConcept(NS, 'BankInfo') ; bankInfoConcept = Object.assign(bankInfoConcept, { name : 'MikeBank', routingNumber : 123456, ... }); ``` but I do not know for sure if it will work when deployed to the JavaScript runtime we use on Hyperledger Fabric (which is not ES6/ES7 compatible)

sstone1 (Fri, 28 Apr 2017 19:04:37 GMT):
Agree that there is a doc error, could you raise a GitHub issue for that?

sstone1 (Fri, 28 Apr 2017 19:06:26 GMT):
And on the subject of arrow functions, I think we're just used to using them everywhere anyway; the main benefit is avoiding having to use this kind of code: ``` function doSomething() { const self = this; doOtherThing(function (result) { self.somethingElse(result); }); } ```

sstone1 (Fri, 28 Apr 2017 19:06:54 GMT):
With `function (args) { ... }` the `this` variable is set to the function

sstone1 (Fri, 28 Apr 2017 19:06:54 GMT):
With `function (args) { ... }` the `this` variable is set to the anonymous callback function

sstone1 (Fri, 28 Apr 2017 19:07:49 GMT):
``` function doSomething() { doOtherThing((result) => { this.somethingElse(result); }); } ``` with arrow functions, the `this` variable is preserved

gauthampamu (Fri, 28 Apr 2017 20:05:50 GMT):
If you update the bna file, what will happen to existing asset registry..is it going to still exist ? In v1.0, it allows you to update chaincode.

gauthampamu (Fri, 28 Apr 2017 20:06:16 GMT):
What exactly is happening under the covers, when you update the chaincode.

gauthampamu (Fri, 28 Apr 2017 20:07:40 GMT):
When is the fabric composer runtime installed on the fabric peers. Is it installed and instantiated only the first time you deploy the bna file. What will happen when you update the bna file

sstone1 (Fri, 28 Apr 2017 20:08:01 GMT):
@gauthampamu if you update the BNA file using `composer network update`, then a transaction is sent to the chaincode that updates the BNA (which is stored in the world state). No chaincode update/modification happens during this process.

sstone1 (Fri, 28 Apr 2017 20:08:33 GMT):
We have not yet exposed the HLF v1.0 chaincode upgrade APIs via composer, but I suspect we will introduce a `composer network upgrade` to upgrade the chaincode

sstone1 (Fri, 28 Apr 2017 20:08:57 GMT):
When you update the BNA file using `composer network update`, no data is lost - all data stored in the world state stays in the world state.

gauthampamu (Fri, 28 Apr 2017 20:10:13 GMT):
lets say you built the bna file with fabric composer runtime version 1.0 and now we have a new version v1.1 or new code base of composer. Are we expected to upgrade using the composer network ugprade..when it is offered..

sstone1 (Fri, 28 Apr 2017 20:12:37 GMT):
you don't have to, but if you wanted new features or bug fixes in the v1.1 release then you would have to perform a `composer network upgrade` to upgrade the chaincode

gauthampamu (Fri, 28 Apr 2017 20:17:49 GMT):
I agree that we don't have to upgrade the runtime for everyone new snapshot but we will need to have way to upgrade the runtime for bugfixes, security fixes or performance fixes.

gauthampamu (Fri, 28 Apr 2017 20:18:42 GMT):
Any idea on when the composer network upgrade will be available. Will it be offered when composer supports v1.0 of fabric.

sstone1 (Fri, 28 Apr 2017 20:26:56 GMT):
Now that Composer does support v1.0 of Fabric, we are looking at how we can exploit v1.0 features in Composer - so expect to see things like that soon.

davidkel (Sat, 29 Apr 2017 12:27:55 GMT):
@Dpkkmr Those assets should have been created when you followed the quickstart tutorial (https://hyperledger.github.io/composer/installing/quickstart.html) before continuing with the command line tutorial. This tutorial does rely on everything remaining from the completion of the quickstart

Dpkkmr (Sat, 29 Apr 2017 12:41:05 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=n3ZXM89hE4X4D3CNA) @davidkel Thanks!

[ ](https://chat.hyperledger.org/channel/composer?msg=n3ZXM89hE4X4D3CNA) @davidkel Thanks! I had missed executing npm test. After executing this I'm able to test it. I had couple of questions, If I have to add more assets from CLI, what is the command for doing it? Can I view all the transaction details using CLI command?

davidkel (Sat, 29 Apr 2017 13:16:15 GMT):
@Dpkkmr there isn't a way to add assets via the cli, in this case you would need to write your own code to add assets (for how to do that you can review the code used by the quickstart tutorial). Sorry there isn't a CLI command to view all transactions.

vagrant@hyperledger-devenv:v0.3.0-51b7e85:/opt/gopath/src/github.com/hyperledger/composer-sample-applications-hlfv1/packages/getting-started/hlfv1$ cat connection.json { "type": "hlfv1", "orderers": [ { "url": "grpc://localhost:7050" } ], "ca": "http://localhost:7054", "peers": [ { "requestURL":"grpc://localhost:7051", "eventURL":"grpc://localhost:7053" }, { "requestURL":"grpc://localhost:7056", "eventURL":"grpc://localhost:7058" } ], "keyValStore": "YOUR_HOME_DIR/.hfc-key-store", "channel": "mychannel", "mspID": "Org1MSP", "deployWaitTime": "300", "invokeWaitTime": "100" }

sstone1 (Sat, 29 Apr 2017 18:29:04 GMT):
@xuzhao103389 that is not the connection profile being used

sstone1 (Sat, 29 Apr 2017 18:29:12 GMT):
`~/.composer-connection-profiles/defaultProfile/connection.json`

sstone1 (Sat, 29 Apr 2017 18:29:34 GMT):
you have not specified a `-p connectionProfileName` flag so it defaults to `defaultProfile`

xuzhao103389 (Sat, 29 Apr 2017 18:29:59 GMT):
oh

sstone1 (Sat, 29 Apr 2017 18:30:43 GMT):
the `-p connectionProfileName` specifies the name of a directory inside `~/.composer-connection-profiles`, e.g. `~/.composer-connection-profiles/connectionProfileName`

sstone1 (Sat, 29 Apr 2017 18:30:53 GMT):
that directory must contain the `connection.json` file

xuzhao103389 (Sat, 29 Apr 2017 18:30:57 GMT):
vagrant@hyperledger-devenv:v0.3.0-51b7e85:/opt/gopath/src/github.com/hyperledger/composer-sample-applications-hlfv1/packages/getting-started$ cat ~/.composer-connection-profiles/defaultProfile/connection.json { "type": "hlf", "membershipServicesURL": "grpc://localhost:7054", "peerURL": "grpc://localhost:7051", "eventHubURL": "grpc://localhost:7053", "keyValStore": "/home/vagrant/.composer-credentials", "deployWaitTime": "300", "invokeWaitTime": "100" }

sstone1 (Sat, 29 Apr 2017 18:31:13 GMT):
OK, that's the problem then - that's a v0.6 connection profile

xuzhao103389 (Sat, 29 Apr 2017 18:31:26 GMT):
can I get a V1.0

sstone1 (Sat, 29 Apr 2017 18:31:27 GMT):
did you follow the HLF v1.0 getting started guide?

xuzhao103389 (Sat, 29 Apr 2017 18:31:28 GMT):
file

xuzhao103389 (Sat, 29 Apr 2017 18:31:34 GMT):
yes

xuzhao103389 (Sat, 29 Apr 2017 18:31:40 GMT):
now it is working for me

xuzhao103389 (Sat, 29 Apr 2017 18:31:45 GMT):
I am using fabrci V1.0

sstone1 (Sat, 29 Apr 2017 18:31:49 GMT):
you should have a profile under `~/.composer-connection-profiles/hlfv1/connection.json`

sstone1 (Sat, 29 Apr 2017 18:32:02 GMT):
and you need to refer to it by using `-p hlfv1` on all commands that use connection profiles

xuzhao103389 (Sat, 29 Apr 2017 18:32:17 GMT):
can you give me the instructions?

sstone1 (Sat, 29 Apr 2017 18:34:14 GMT):
instructions for what?

xuzhao103389 (Sat, 29 Apr 2017 18:35:53 GMT):
can I copy composer-sample-applications-hlfv1/packages/getting-started/hlfv1/connection.json into ~/.composer-connection-profiles/hlfv1/connection.json

xuzhao103389 (Sat, 29 Apr 2017 18:35:59 GMT):
and then run the command

xuzhao103389 (Sat, 29 Apr 2017 18:36:10 GMT):
composer identity issue -n 'digitalproperty-network' -i admin -s Xurw3yU9zI0l -p hlfv1 -u -a "net.biz.digitalPropertyNetwork.Person#mae@biznet.org"

sstone1 (Sat, 29 Apr 2017 18:36:23 GMT):
does the file `~/.composer-connection-profiles/hlfv1/connection.json` already exist?

sstone1 (Sat, 29 Apr 2017 18:36:31 GMT):
the v1.0 getting started guide should have created it

xuzhao103389 (Sat, 29 Apr 2017 18:36:31 GMT):
yes

sstone1 (Sat, 29 Apr 2017 18:36:39 GMT):
so you just need to change the command

sstone1 (Sat, 29 Apr 2017 18:36:49 GMT):
composer identity issue *-p hlfv1* -n 'digitalproperty-network' -i admin -s Xurw3yU9zI0l -p hlfv1 -u -a "net.biz.digitalPropertyNetwork.Person#mae@biznet.org"

sstone1 (Sat, 29 Apr 2017 18:37:11 GMT):
most of the commands support the `-p connectionProfileName` argument

xuzhao103389 (Sat, 29 Apr 2017 18:37:30 GMT):
but as you know my content of connection file is

xuzhao103389 (Sat, 29 Apr 2017 18:37:30 GMT):
{ "type": "hlf", "membershipServicesURL": "grpc://localhost:7054", "peerURL": "grpc://localhost:7051", "eventHubURL": "grpc://localhost:7053", "keyValStore": "/home/vagrant/.composer-credentials", "deployWaitTime": "300", "invokeWaitTime": "100" }

xuzhao103389 (Sat, 29 Apr 2017 18:37:39 GMT):
that is for V0.6

sstone1 (Sat, 29 Apr 2017 18:37:48 GMT):
that was the defaultProfile file `~/.composer-connection-profiles/defaultProfile/connection.json`

sstone1 (Sat, 29 Apr 2017 18:38:00 GMT):
you can have multiple connection profiles

xuzhao103389 (Sat, 29 Apr 2017 18:38:05 GMT):
ok

xuzhao103389 (Sat, 29 Apr 2017 18:38:17 GMT):
vagrant@hyperledger-devenv:v0.3.0-51b7e85:/opt/gopath/src/github.com/hyperledger/composer-sample-applications-hlfv1/packages/getting-started/hlfv1$ composer identity issue -n 'digitalproperty-network' -i admin -s Xurw3yU9zI0l -p hlfv1 -u -a "net.biz.digitalPropertyNetwork.Person#mae@biznet.org"

sstone1 (Sat, 29 Apr 2017 18:38:19 GMT):
if you run `cat ~/.composer-connection-profiles/hlfv1/connection.json` you should see the v1.0 connection profile

xuzhao103389 (Sat, 29 Apr 2017 18:38:27 GMT):
now it looks like my command is hanging

sstone1 (Sat, 29 Apr 2017 18:41:45 GMT):
can you paste in the v1.0 connection profile please

xuzhao103389 (Sat, 29 Apr 2017 18:41:53 GMT):
ok

xuzhao103389 (Sat, 29 Apr 2017 18:50:32 GMT):
now it is working thanks @sstone1

I am using the example from the link https://hyperledger.github.io/composer/managing/participant-add.html

xuzhao103389 (Sat, 29 Apr 2017 18:55:53 GMT):
not sure what is the problem

sstone1 (Sat, 29 Apr 2017 18:56:45 GMT):
`-i admin -s Xurw3yU9zI0l` have to be valid Hyperledger Fabric credentials

sstone1 (Sat, 29 Apr 2017 18:57:00 GMT):
those are the default ID and secret from Hyperledger Fabric v0.6

sstone1 (Sat, 29 Apr 2017 18:57:14 GMT):
the default ID and secret for Hyperledger Fabric v1.0 is `-i admin -s adminpw`

xuzhao103389 (Sat, 29 Apr 2017 18:57:20 GMT):
oh

xuzhao103389 (Sat, 29 Apr 2017 18:57:21 GMT):
thanks

sstone1 (Sat, 29 Apr 2017 18:57:44 GMT):
for the `composer identity issue` command, you have not specified a value (the new user ID) for the `-u` flag

sstone1 (Sat, 29 Apr 2017 18:57:49 GMT):
the example shows `-u maeid1`

what is @ ibm

sstone1 (Sat, 29 Apr 2017 19:02:54 GMT):
it _was_ part of the name of the sample digital property business network

sstone1 (Sat, 29 Apr 2017 19:02:59 GMT):
but we have removed it a long time ago

sstone1 (Sat, 29 Apr 2017 19:03:04 GMT):
guess we didn't update all of the docs :)

xuzhao103389 (Sat, 29 Apr 2017 19:03:10 GMT):

Hi When I'm checking Rest API I'm getting version mismatch Exception. Can someone help me is solving this version compatibility issue?

jworthington (Sun, 30 Apr 2017 11:33:49 GMT):
Following composer quickstart for v1 Fabric. Install seemed fine. npm test passed sample test but failed after Adding default land titles to the asset registry. no connection.json file. Tried adding connection.json from github. Fails after Adding default land titles to the asset registry, but with connection refused. Error: Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 127.0.0.1:7054] Looks like there are no v1.0 Fabric dockers started? Am I supposed to have started a v1.0 Fabric network first? Am I supposed to have a composer instance running before running the sample app?

davidkel (Sun, 30 Apr 2017 12:14:54 GMT):
@jworthington sounds like that could be a bug could you raise an issue please ?

jworthington (Sun, 30 Apr 2017 12:45:49 GMT):
I'll try, having not done that before. In GIT or is this in JIRA?

jworthington (Sun, 30 Apr 2017 13:11:20 GMT):
Raised issue in Git.

sstone1 (Sun, 30 Apr 2017 16:05:56 GMT):
@dklesev the new UI, `composer-playground`, does not yet support connection profiles - that work should be finished this week :fingers_crossed: at which point you'll find documentation on the website about how to set it up.

sstone1 (Sun, 30 Apr 2017 16:07:03 GMT):
@Dpkkmr you have deployed a business network using an old version (0.5.12) of `composer-cli` and are trying to use a new version (0.7.0) of `composer-rest-server`. You either need to upgrade `composer-cli` to 0.7.0 and redeploy the business network, or downgrade `composer-rest-server` to 0.5.12.

sstone1 (Sun, 30 Apr 2017 16:07:40 GMT):
Upgrade `composer-cli` - `npm upgrade -g composer-cli` Downgrade `composer-rest-server` - `npm install -g composer-rest-server@0.5.12`

torresjeff (Sun, 30 Apr 2017 16:17:28 GMT):
Hi, I have a "networks" object on my defaultProfile's conection.json with the following value: "digitalproperty-network": "ec45b2bc2fc7fdc06a064a82a21c357223967acbfc0e1145e29a801f3b30a013"

torresjeff (Sun, 30 Apr 2017 16:17:53 GMT):
where does this come from? is it the chaincode id of the deployed network?

sstone1 (Sun, 30 Apr 2017 16:18:14 GMT):
correct

sstone1 (Sun, 30 Apr 2017 16:18:29 GMT):
the `composer network deploy` command adds it to the connection profile after a successful deploy

torresjeff (Sun, 30 Apr 2017 16:20:44 GMT):
I'm trying to deploy my bna file to the bluemix blockchain service (v0.6), but the request times out, although I can see on my Blockchain dashboard that the deploy is indeed being invoked

torresjeff (Sun, 30 Apr 2017 16:21:53 GMT):
should I believe the blockchain dashboard or the composer cli output?

sstone1 (Sun, 30 Apr 2017 16:22:11 GMT):
is there a running chaincode in the bluemix console?

torresjeff (Sun, 30 Apr 2017 16:22:33 GMT):
currently have 3 chaincode IDs

torresjeff (Sun, 30 Apr 2017 16:22:55 GMT):
should I try recreating it from scratch?

sstone1 (Sun, 30 Apr 2017 16:23:03 GMT):
i guess it's possible that the deployWaitTime needs to be increased?

torresjeff (Sun, 30 Apr 2017 16:23:22 GMT):
I increased it to 10 minutes and still getting the time out

torresjeff (Sun, 30 Apr 2017 16:23:41 GMT):
what I don't understand is why I can see the deploy command on the console

sstone1 (Sun, 30 Apr 2017 16:23:46 GMT):
anything in the peer logs?

if it helps

sstone1 (Sun, 30 Apr 2017 17:59:14 GMT):
@torresjeff which user ID are you using to try the deployment?

sstone1 (Sun, 30 Apr 2017 17:59:30 GMT):
https://github.com/hyperledger/composer/issues/794 says user_type4_1

torresjeff (Sun, 30 Apr 2017 18:00:01 GMT):
yep, this time i tried user_type1_0

torresjeff (Sun, 30 Apr 2017 18:00:09 GMT):
the thing is it wont let me deploy with admin

sstone1 (Sun, 30 Apr 2017 18:02:16 GMT):
why not?

sstone1 (Sun, 30 Apr 2017 18:02:37 GMT):
i've only ever deployed with admin or WebAppAdmin... not sure what the other types are for

sstone1 (Sun, 30 Apr 2017 18:02:50 GMT):
user_type4_* seems to not work at all

torresjeff (Sun, 30 Apr 2017 18:03:41 GMT):
other times I've tried with admin i get 'Error: sql: no rows in result set'

torresjeff (Sun, 30 Apr 2017 18:03:49 GMT):
but just tried again and its deploying

sstone1 (Sun, 30 Apr 2017 18:03:56 GMT):
user_type1_0 works for me

sstone1 (Sun, 30 Apr 2017 18:04:07 GMT):
that means you've enrolled somewhere else using the admin ID

torresjeff (Sun, 30 Apr 2017 18:04:39 GMT):
would opening the blockchain console count as being enrolled?

sstone1 (Sun, 30 Apr 2017 18:04:50 GMT):
no that wouldn't count

torresjeff (Sun, 30 Apr 2017 18:05:06 GMT):
other than that i haven't "enrolled" somewhere else

sstone1 (Sun, 30 Apr 2017 18:05:08 GMT):
the secret gets regenerated each time you create a new service - could that be it?

torresjeff (Sun, 30 Apr 2017 18:05:59 GMT):
you mean like trying to paste a secret from a previous service I created?

sstone1 (Sun, 30 Apr 2017 18:06:27 GMT):
yeah

torresjeff (Sun, 30 Apr 2017 18:07:00 GMT):
always making sure to copy the credentials from the service im using

torresjeff (Sun, 30 Apr 2017 18:07:22 GMT):
also, if i paste an incorrect secret that wouldn't let me deploy at all or would it?

sstone1 (Sun, 30 Apr 2017 18:15:39 GMT):
the other possiblity is that there is a `member.admin` file in your `keyValStore` directory

sstone1 (Sun, 30 Apr 2017 18:15:59 GMT):
and that file contains an old certificate that does not match the Fabric instance you are trying to deploy to

torresjeff (Sun, 30 Apr 2017 18:19:56 GMT):
will try deleting

torresjeff (Sun, 30 Apr 2017 18:25:01 GMT):
I'm sorry for bothering you so much, but could you try with my config to check if it deploys?

that is my connection.json, i have it located under /home/jeff/.composer-connection-profiles/blockchain-connectionprofile

torresjeff (Sun, 30 Apr 2017 18:27:18 GMT):
my composer network deploy command: `composer network deploy -a carauction-network.bna --enrollId WebAppAdmin --enrollSecret 5da5af09b6 -p blockchain-connectionprofile`

torresjeff (Sun, 30 Apr 2017 18:29:10 GMT):
tried with both admin and WebAppAdmin but still timing out

sstone1 (Sun, 30 Apr 2017 18:30:36 GMT):
both i get Error: Identity or token does not match which i'd expect given you've already tried with them

torresjeff (Sun, 30 Apr 2017 18:30:50 GMT):
would user_type1_1 work?

sstone1 (Sun, 30 Apr 2017 18:31:01 GMT):
yeah, user_type1_0 worked for me

torresjeff (Sun, 30 Apr 2017 18:31:19 GMT):
already tried with 1_1

torresjeff (Sun, 30 Apr 2017 18:31:23 GMT):
so maybe it wouldn't work for you

torresjeff (Sun, 30 Apr 2017 18:31:57 GMT):
already tried with 1_0*

sstone1 (Sun, 30 Apr 2017 18:32:20 GMT):
deploying now

sstone1 (Sun, 30 Apr 2017 18:36:34 GMT):
worked for me, just deployed 9fef41763488a9786d964a85d6a7646f60a6492762ac2f9d31b7d4e7085aad85

torresjeff (Sun, 30 Apr 2017 18:36:45 GMT):
hmmm

torresjeff (Sun, 30 Apr 2017 18:37:05 GMT):
did you deploy carauction-network?

sstone1 (Sun, 30 Apr 2017 18:37:14 GMT):
yep

torresjeff (Sun, 30 Apr 2017 18:37:51 GMT):
wow hmm

torresjeff (Sun, 30 Apr 2017 18:38:01 GMT):
really don't know what's wrong then

torresjeff (Sun, 30 Apr 2017 18:38:29 GMT):
what path did you set for keValStore?

sstone1 (Sun, 30 Apr 2017 18:38:56 GMT):
`"keyValStore": "/Users/sstone1/.composer-credentials/bluemix",`

torresjeff (Sun, 30 Apr 2017 18:39:21 GMT):
that's for mac right?

sstone1 (Sun, 30 Apr 2017 18:40:45 GMT):
yep

torresjeff (Sun, 30 Apr 2017 18:46:37 GMT):
one question, is deploying from the composer-ui the same as the `composer network deploy` command?

sstone1 (Sun, 30 Apr 2017 18:47:05 GMT):
yep

torresjeff (Sun, 30 Apr 2017 18:56:55 GMT):
will try ubuntu live desktop to see if it works

torresjeff (Sun, 30 Apr 2017 19:42:57 GMT):
`.composer-credentials` and `.composer-connection-profiles` folder should be created manually, correct?

torresjeff (Sun, 30 Apr 2017 22:57:42 GMT):
had to try it on a mac and it worked

torresjeff (Sun, 30 Apr 2017 23:05:51 GMT):
@sstone1 apparently I found a bug. All this time I tried with`"deployWaitTime": "600"` on my `connection.json` in order to give it some extra time to deploy. Now I tried with `"deployWaitTime": "300"` and it worked

torresjeff (Sun, 30 Apr 2017 23:05:51 GMT):

both on mac and ubuntu didn't work with 600

torresjeff (Sun, 30 Apr 2017 23:18:50 GMT):
I have a question regarding the `package.json` in my bna file. Does the `name` property in the `package.json` define the network identifier? Also, do I necessarily have to include other things like the `scripts` property?

davidkel (Mon, 01 May 2017 08:23:32 GMT):
@abcoathup could you raise a github issue about the docs please ? the examples with sudo should be changed to not use sudo

torresjeff (Mon, 01 May 2017 08:29:43 GMT):
Is it possible to get an asset from a registry and store it in an object? I get the following error when I try to do that: `Use Serializer.toJSON to convert resource instances to JSON objects.` I have tried getting the serializer with `businessNetworkDefinition.getSerializer()` and then calling its `toJSON()` method passing in the result from the promise as a parameter but I get the following error: `Serializer.toJSON only accepts instances of Resource.` Any idea of what it could be?

torresjeff (Mon, 01 May 2017 08:30:45 GMT):
until now I have to manually specify each property of the asset to be able to store it in a javascript object

torresjeff (Mon, 01 May 2017 08:32:57 GMT):
btw the error appears when I use the `registry.getAll()` method, it seems to work with `registry.get()`

dselman (Mon, 01 May 2017 09:22:19 GMT):
@torresjeff `registry.getAll()` returns an array of Resources -- you need to pass each element to the serializer to create a JS Object suitable for long-lived serialization.

dselman (Mon, 01 May 2017 09:22:26 GMT):
(see JSDoc for details)

torresjeff (Mon, 01 May 2017 15:08:13 GMT):
Thanks @dselman

torresjeff (Mon, 01 May 2017 15:13:16 GMT):
Up until now i have my app running locally, what if i want to upload it to bluemix? what happens to the `.composer-connection-profiles` and `.composer-credentials` folders? where do I put those?

One more non-technical question ... while it would be hard to do an apples to apples compare ... has anyone looked at performance of a simple app built with composer vs the same app written directly in Go? Wondering if there is a notable difference in overall performance. I'm not exactly ready to drop back and start writing it all in Go ... was just trying to get my head around it. Thanks,

Hi, I recently set up a new version of a project which involved doing an npm install I'm now getting the error ``` Unhandled error for request POST /api/com.loyyal.goyyal.Operation: ValidationError: The `com_loyyal_goyyal_Operation` instance is not valid. Details: `uuid` can't be set (value: "12d38540-ec7f-4252-91a2-2...8ea"). at /Users/johnwhitton/loyyal/Projects/goyyal/fabric/node_modules/loopback-datasource-juggler/lib/dao.js:348:12 ``` I believe it's because the npm install picked up a later version of loopback-datasource-juggler Has anyone seen anything like this?

JohnWhitton (Mon, 01 May 2017 22:21:24 GMT):
btw definition of operation is ``` transaction Operation identified by uuid { o String uuid o OpKind kind o Integer amount --> Currency currency --> Balance from optional --> Balance to o String err optional } ```

Hi I'm new to composer and blockchain development, Been reading and trying up Fabric with composer recently, but one thing I would like to know: Is there anyway to verify an asset that's being transferred is the same asset from the origin despite being modified in the process? Eg: X have a message to send to Z, but he first sends the message to Y, and Y changes the message before sending to Z. Is there any way for Z to find out this message is from X? I imagine it would involve checking the hash for each block. Any other suggestions? Thanks!

pospi (Tue, 02 May 2017 01:08:23 GMT):
Just looking for others requesting what I'm after and came across this issue: https://github.com/hyperledger/composer/issues/739 Is there any view to being able to do this on the chaincode side, rather than externally? It would be really nice to be able to modify transaction data before it is persisted. Otherwise, the trusted execution environment for such operations has to extend outside the chaincode, and I don't think that's ideal from a security standpoint.

Hi, I have been able to run my nodejs app locally, connecting to my Bluemix Blockchain service. In order to keep the connection alive I have to ping the network every 30 seconds. But this solution doesn't seem to work in Bluemix, I get the following error after some time: ```Error: {"created":"@1493693076.837780349","description":"Secure read failed","file":"../src/core/lib/security/transport/secure_endpoint.c","file_line":157,"grpc_status":14,"referenced_errors":[{"created":"@1493693076.837767866","description":"OS Error","errno":104,"file":"../src/core/lib/iomgr/tcp_posix.c","file_line":229,"os_error":"Connection reset by peer","syscall":"recvmsg"}]}```

torresjeff (Tue, 02 May 2017 03:12:08 GMT):
any idea why it works on my local machine but not on bluemix?

torresjeff (Tue, 02 May 2017 03:17:35 GMT):
have tried setting the ping interval to 15 secs, still get the same error on bluemix but runs fine locally

has anyone tried to use remote fabric for connection profiles?

yongkook (Tue, 02 May 2017 04:13:31 GMT):
I just installed new composer-cli, and using -p for remote fabric, but it keeps picking up default fabric which is 'localhost'...am I doing something wrong here?

you're passing `./connection_remote.json` as an argument for the profile, you should only specify the name of the profile, not the json containing the data itself

by default, composer cli will look for a folder with the name of the profile (eg: `remote`) under `/home//.composer-connection-profiles/`

torresjeff (Tue, 02 May 2017 04:21:04 GMT):
that profile folder should have a `connection.json` (not `connection_remote.json`) with the info from the screenshot you posted

In a transaction, I want to find a free asset. I understand that we can't do queries, so am attempting to use getAll() and then loop through. Does anyone have an example of this? I tried forEach but get the following error: assetRegistry.getAll(...).forEach is not a function I don't know what version of Javascript is being used, so not sure what is valid syntax

torresjeff (Tue, 02 May 2017 04:51:25 GMT):
try: ```assetRegistry.getAll() .then((assets) => { for (var i = 0; i < assets.length; i++) { console.log(serializer.toJSON(assets[i])); } }) ```

torresjeff (Tue, 02 May 2017 04:52:58 GMT):
`serializer` is a variable i defined as `var serializer = businessNetworkDefinition.getSerializer();`

[ ](https://chat.hyperledger.org/channel/composer?msg=PwvzeM4gihyj5jq5J) @JohnWhitton we tightened up the REST API validation a while ago to stop users sending in IDs for transactions, which are generated by Composer. Just remove the `uuid` property from your POST request.

sstone1 (Tue, 02 May 2017 07:03:38 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=MQm4XfZMMNhYHYwEZ) @pospi issue #739 is a UI helper to search for transactions relevant to the asset registry you're currently browsing

pospi (Tue, 02 May 2017 07:08:23 GMT):
Yeah, exactly... a UI helper. It's the "we'd pre-fill information part" that gets me- it implies that a good way to setup a link between a transaction & an asset is to set that data in the UI. I think at least some of these kinds of references should be initialised at transaction time (on the chaincode side), otherwise you're trusting the UI/app to do far too much IMO...

pospi (Tue, 02 May 2017 07:09:43 GMT):
@sstone1 > we tightened up the REST API validation a while ago to stop users sending in IDs for transactions, which are generated by Composer. Just remove the `uuid` property from your POST request. but this still gets inited by `composer-client` rather than within the blockchain, correct? Just checking...

sstone1 (Tue, 02 May 2017 07:10:46 GMT):
Correct, for the moment; I'd like to get rid of the transaction ID generation and just use the underlying Fabric transaction ID instead.

sstone1 (Tue, 02 May 2017 07:11:04 GMT):
It would be easier to understand if Composer transaction ID === Fabric transaction ID

dselman (Tue, 02 May 2017 07:11:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=GPmMyumzKBDZWPKzY) @pospi I don't think I understand. A transaction may be related to an asset -- and those relationships have to be set by the client, as only the client can know the intention of the transaction. E.g. if the client submits a `house purchase` transaction, they would have to set the relationship to point to a `house`.

dselman (Tue, 02 May 2017 07:13:43 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=xbRZ6noF2TMJvn3iz) @sstone1 as long as we can also support correlation ids somehow. E.g. client submits a transaction and then gets notifications based on that transaction.

sstone1 (Tue, 02 May 2017 07:14:35 GMT):
Yeah, that should be fine :+1:

pospi (Tue, 02 May 2017 07:17:53 GMT):
@dselman maybe I'm not explaining it very well... am starting to doubt myself! We're really just trying to workaround the inability to run logic when adding an asset- this creates a trust problem for us with administrative metadata like creation timestamps, invoking participant IDs and bidirectional links between asset & transaction

dselman (Tue, 02 May 2017 07:20:13 GMT):
You can define a transaction that creates an asset, and run custom validation logic in your TP function. E.g. see `placeOrder` here: https://github.com/hyperledger/composer-sample-networks/blob/master/packages/vehicle-lifecycle-network/lib/manufacturer.js#L21

pospi (Tue, 02 May 2017 07:20:15 GMT):
Basically if adding an asset can only insert data then all that info has to be either trusted by the client, or added in a followup transaction run against the asset. The way we've been trying to do it is using transactions to do the creation, to avoid having to run two separate calls which would make things much slower.

pospi (Tue, 02 May 2017 07:24:24 GMT):
cool.. haven't seen that one but it's basically what we're doing. The problem is that you have to define the transaction -> asset relationship in the payload, since it can't be modified after sending. So a) you can't use a real relationship because the new asset doesn't exist when the transaction starts; and b) you have to trust the client not to lie about that ID- there's nothing to stop them sending data to create a relationship with some other asset instead of the one about to be created with the same ID as the transaction. If that makes sense?

pospi (Tue, 02 May 2017 07:24:24 GMT):

pospi (Tue, 02 May 2017 07:25:46 GMT):
We definitely need to be able to look up the asset associated with a transaction as well as all transactions associated with an asset in our use-cases...

dselman (Tue, 02 May 2017 07:26:58 GMT):
I'm not sure it does make sense... ;-) The intent of the transaction is "create a thing, with this id, that is related to this other thing with this id" -- I'm not sure how else you could do it. TP functions can inspect asset/participant registries and can CRUD assets and participants.

dselman (Tue, 02 May 2017 07:27:58 GMT):

throwing an error should display the message and you should not see the transaction inserted. The error is displayed at the bottom of the "submit transaction" modal dialog

pospi (Tue, 02 May 2017 08:02:22 GMT):
@sstone1 my current experience with transactions is that they complain if there is no identifier. Could be only for transactions which inherit from a base transaction type. If we get rid of that validation the rest might 'just work', I'd rather not have to comb back through later and remove all explicitly provided transaction IDs

sstone1 (Tue, 02 May 2017 08:15:55 GMT):
is that using the Node.js APIs or the REST APIs or the playground?

pospi (Tue, 02 May 2017 08:19:14 GMT):
Nodejs APIs, via `BusinessNetworkConnection.submitTransaction()`

sstone1 (Tue, 02 May 2017 08:19:58 GMT):
How are you creating the transaction object? `factory.newInstance` ?

sstone1 (Tue, 02 May 2017 08:20:08 GMT):
or `serializer.fromJSON` ?

pospi (Tue, 02 May 2017 08:21:08 GMT):
Yeah. Though, caveat alert, it might be necessary in the meantime: If you're going to disable setting transaction IDs from the outside then it'll be impossible to get back that ID for requerying until the event service stuff is integrated. At least, that's my current understanding. We've never gotten as far as actually integrating with the event service as we weren't sure if it would be changing for v1. Dan mentioned that in v1 transactions can return data back to the outside world so that would solve it too.

pospi (Tue, 02 May 2017 08:21:25 GMT):
ah actually, we're using `factory.newResource`

pospi (Tue, 02 May 2017 08:22:00 GMT):
is that the problem? As far as I could tell from docs one was a deprecated version of the other.

sstone1 (Tue, 02 May 2017 08:22:02 GMT):
cool, switch to `factory.newTransaction` ;)

pospi (Tue, 02 May 2017 08:22:33 GMT):
doh! that's lame. Now we can't have a single resource parsing helper ><

pospi (Tue, 02 May 2017 08:22:49 GMT):
*adds another curried parameter to the function...

pospi (Tue, 02 May 2017 08:24:15 GMT):
how do you expect we'll be able to retrieve the sent transaction once the ID parameter is taken out though? that seems like a problem

sstone1 (Tue, 02 May 2017 08:31:24 GMT):
not sure, we could update the transaction instance passed into submitTransaction

sstone1 (Tue, 02 May 2017 08:31:37 GMT):
`factory.newTransaction` sets the transaction ID at that point

pospi (Tue, 02 May 2017 08:36:55 GMT):
oh does it? well that's totally fine then, I can work with that!

@sstone1 following up on @JohnWhitton question: right now, we rely on passing a UUID to transactions we submit to avoid double posting. We generate a UUID in our application stack, store it in a local queue, then post the transaction and retry if get a timeout or other issue. What do you suggest now that a UUID cannot be passed in?

@sstone1 Additionally, could you be more specific as to when the validation change occurred. You said earlier "we tightened up the REST API validation a while ago to stop users sending in IDs for transactions", and one path we are exploring for now is to pin down the version to avoid taking in this change. It's temporary, but we have a release deadline we're hitting against and can't redo something that low level now.

Any help on this error? It seems to be a login problem.

davidkel (Tue, 02 May 2017 15:34:03 GMT):
@jje your are using a v0.6 connectionprofile to try to connect to a v1.0-alpha runtime. if you have followed the getting started for v1 then it will have created a profile called hlfv1. add `-p hlfv1` to the network deploy command you tried to use this profile.

jje (Tue, 02 May 2017 15:37:35 GMT):
If I do this I get:

jje (Tue, 02 May 2017 15:37:43 GMT):

torresjeff (Tue, 02 May 2017 15:40:16 GMT):
@dselman wouldn't it be better if the `credentials` object in the `COMPOSER_CONFIG` saved the the credentials like: ``` "credentials": { "hlfabric": { "id": "admin", "secret": "Xurw3yU9zI0l" } } ```

torresjeff (Tue, 02 May 2017 15:40:16 GMT):
@dselman wouldn't it be better if the `credentials` object in the `COMPOSER_CONFIG` environment variable saved the the credentials like: ``` "credentials": { "hlfabric": { "id": "admin", "secret": "Xurw3yU9zI0l" } } ```

torresjeff (Tue, 02 May 2017 15:40:16 GMT):

davidkel (Tue, 02 May 2017 15:40:31 GMT):
@jje opps sorry also noted that the id and secret are wrong, you need `-i admin -s adminpw`

davidkel (Tue, 02 May 2017 15:40:31 GMT):
@jje opps sorry should have also said that the id and secret are wrong, you need `-i admin -s adminpw`

torresjeff (Tue, 02 May 2017 15:40:38 GMT):
this way we can access the `id` and `secret` without having to know them before hand

jje (Tue, 02 May 2017 15:42:10 GMT):
works, great, thx!

torresjeff (Tue, 02 May 2017 15:49:12 GMT):
with that change we could connceto to the business network this way: ``` var config = JSON.parse(process.env.COMPOSER_CONFIG); bizNetworkConnection.connect(CONNECTION_PROFILE_NAME, businessNetworkIdentifier, config.credentials.hlfabric.id, config.credentials.hlfabric.secret); ```

torresjeff (Tue, 02 May 2017 15:58:35 GMT):
maybwe we could event set an array of credentials like so: ``` "credentials": { "hlfabric": [ { "id": "admin", "secret": "Xurw3yU9zI0l" }, { "id": "user_type1_0", "secret": "Xurw3yU9zI0l" } ] } ```

torresjeff (Tue, 02 May 2017 16:06:01 GMT):
@tennenjl were you able to keep a persistent connection to your blockchain service with your app deployed on bluemix? or does it time out eventually?

tennenjl (Tue, 02 May 2017 16:07:34 GMT):
@torresjeff I believe it disconnects eventually, but I believe my code calls disconnect now

torresjeff (Tue, 02 May 2017 16:07:48 GMT):
oh

torresjeff (Tue, 02 May 2017 16:08:02 GMT):
so you have to connect every time you want to invoke chaincode and then disconnect?

tennenjl (Tue, 02 May 2017 16:09:57 GMT):
Not sure if you "have to" but seems like the cleaner approach

torresjeff (Tue, 02 May 2017 16:10:22 GMT):
doesn't it take quite a while to connect?

tennenjl (Tue, 02 May 2017 16:10:27 GMT):
get your connection, then invoke the function then disconnect

torresjeff (Tue, 02 May 2017 16:10:33 GMT):
kinda worried about the time it takes

tennenjl (Tue, 02 May 2017 16:11:57 GMT):
Right, and that may be something that we need to consider as well.

tennenjl (Tue, 02 May 2017 16:12:56 GMT):
But, to answer your original question, if I remember correctly, I think the connect would eventually drop

tennenjl (Tue, 02 May 2017 16:12:56 GMT):
But, to answer your original question, if I remember correctly, I think the connection would eventually drop

torresjeff (Tue, 02 May 2017 16:13:18 GMT):
i was able to keep the connection alive by calling `ping()` every 30 seconds, but it only works locally

torresjeff (Tue, 02 May 2017 16:13:25 GMT):
doesn't work when I upload my app to bluemix

tennenjl (Tue, 02 May 2017 16:16:36 GMT):
@torresJeff, it might make sense to test for a connection initially and then create the connection if it no longer exists, would be good to get input from the team on best practices

torresjeff (Tue, 02 May 2017 16:17:47 GMT):
that makes sense

torresjeff (Tue, 02 May 2017 16:17:51 GMT):
thanks!

torresjeff (Tue, 02 May 2017 17:13:26 GMT):
@tennenjl btw, the timeout is because of the blockchain service right? not composer

tennenjl (Tue, 02 May 2017 17:16:24 GMT):
@torresjeff. Not sure. Ask the SMEs :-)

feronti (Tue, 02 May 2017 17:50:33 GMT):

cassolato (Tue, 02 May 2017 18:16:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=3G3Y8Wnn76GQw4nX9) @dselman Yes.. is working perfect! But.. when I try to use the bluemix profile I am getting this error.

tennenjl (Tue, 02 May 2017 18:25:34 GMT):
@torresjeff any luck?

sstone1 (Tue, 02 May 2017 19:37:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=KkYfw7bZMhNyXG5o2) @torresjeff the timeout occurs because of the way the event hub works in Hyperledger Fabric v0.6. The Node.js client for Fabric `hfc` maintains a persistent connection to the event hub but does not cope well with network blips/disconnects etc (it just kills the client). Persistent connections aren't really cloud friendly as the network/routing will just terminate idle connections after a while.

sstone1 (Tue, 02 May 2017 19:38:07 GMT):
`ping()` won't resolve that as it won't trigger any events to be sent. You need to submit an "invoke" transaction to trigger new blocks/events, and that means calling a CRUD operation, submitting a transaction etc.

sstone1 (Tue, 02 May 2017 19:39:03 GMT):
Nothing the Composer team can do about that. I believe the Fabric team have introduced a keep-alive ping or something into v1.0 and _hopefully_ made `fabric-client` a bit more resilient

pascallouis (Tue, 02 May 2017 19:46:22 GMT):
@sstone1 following up on @JohnWhitton question: right now, we rely on passing a UUID to transactions we submit to avoid double posting. We generate a UUID in our application stack, store it in a local queue, then post the transaction and retry if get a timeout or other issue. What do you suggest now that a UUID cannot be passed in?

pascallouis (Tue, 02 May 2017 19:46:34 GMT):
@sstone1 Additionally, could you be more specific as to when the validation change occurred. You said earlier "we tightened up the REST API validation a while ago to stop users sending in IDs for transactions", and one path we are exploring for now is to pin down the version to avoid taking in this change. It's temporary, but we have a release deadline we're hitting against and can't redo something that low level now.

pascallouis (Tue, 02 May 2017 19:46:39 GMT):
(Reposting from earlier.)

sstone1 (Tue, 02 May 2017 19:50:00 GMT):
Me and @dselman discussed this earlier. You're relying on behaviour that is a side effect, i.e. we didn't design it to be used that way and we think the way we store transactions will change in the future (https://github.com/hyperledger/composer/issues/55).

sstone1 (Tue, 02 May 2017 19:50:26 GMT):
You could use an asset in an asset registry to record whether or not the transaction has occurred.

sstone1 (Tue, 02 May 2017 19:50:48 GMT):
Let me try and find out when the change went in...

torresjeff (Tue, 02 May 2017 19:51:26 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=RjFRwpa8bs9zcpSgL) @sstone1 so would this be a good idea? I'm guessing `ping()` won't work if the connection is dropped. SO will trying to `ping()` the network before invoking the chaincode and make the connection if ping doesn't work a viable solution?

sstone1 (Tue, 02 May 2017 19:51:53 GMT):
On a related note, there's a discussion about whether or not it makes sense for the model to include a transaction ID since it's really under Composer control: https://github.com/hyperledger/composer/issues/488

sstone1 (Tue, 02 May 2017 19:53:49 GMT):
@pascallouis the changes went into v0.5.6

sstone1 (Tue, 02 May 2017 19:55:00 GMT):
@torresjeff `ping()` does not fix the problem. The problem is caused by the event hub, and events are only published on actual transactions. `ping()` is a read-only chaincode query that does not create a transaction.

pascallouis (Tue, 02 May 2017 19:55:06 GMT):
@sstone1 thanks for that, we got 'lucky' and were using 0.5.5

sstone1 (Tue, 02 May 2017 19:55:42 GMT):
@torresjeff you could (probably should) have multiple instances of your application running so when one crashes another is still running to take over

pascallouis (Tue, 02 May 2017 19:56:05 GMT):
Currently, we use an `OperationResult` object that we create when a transaction completes.

sstone1 (Tue, 02 May 2017 19:56:26 GMT):
And you store that in an OperationResult registry?

pascallouis (Tue, 02 May 2017 19:56:30 GMT):
Yes.

pascallouis (Tue, 02 May 2017 19:56:57 GMT):
Do you suggest fetching this, and if it already exists, aborting the transaction or doing a noop? i.e. implementing idempotency ourselved?

pascallouis (Tue, 02 May 2017 19:56:57 GMT):
Do you suggest fetching this, and if it already exists, aborting the transaction or doing a noop? i.e. implementing idempotency ourselves?

sstone1 (Tue, 02 May 2017 19:57:14 GMT):
It should fail when you call `registry.add(newOperationResult)`

sstone1 (Tue, 02 May 2017 19:58:30 GMT):
for a duplicate newOperationResult i mean

pascallouis (Tue, 02 May 2017 20:00:53 GMT):
My experience is that transactional boundaries are per registry... so if this fails but we do other things (like in our case, modify a Balance asset), we get in a partial state.

pascallouis (Tue, 02 May 2017 20:01:20 GMT):
Or am I mistaken? Doing it wrong?

sstone1 (Tue, 02 May 2017 20:02:48 GMT):
Mistaken - everything you do in a transaction processor function is contained in a single Fabric transaction that either commits or fails and rolls back all changes

pascallouis (Tue, 02 May 2017 20:03:46 GMT):
Will give it another try then.

pascallouis (Tue, 02 May 2017 20:04:33 GMT):
Thanks a lot @sstone1, it's hard to get this level of detail otherwise :)

pascallouis (Tue, 02 May 2017 20:05:53 GMT):
What do you think of this pattern then: - add operation result (fails if already there, protecting against double execution) - do the work - record the work in the operation result

pascallouis (Tue, 02 May 2017 20:08:01 GMT):
And having a historian component, especially with notifications, would be huge for our app.

sstone1 (Tue, 02 May 2017 20:08:49 GMT):
looks good to me, and np :)

sstone1 (Tue, 02 May 2017 20:09:29 GMT):
on the notification front - we're starting on events at the moment - you will soon be able to emit custom events from within a transaction processor function

pascallouis (Tue, 02 May 2017 20:11:28 GMT):
meanwhile, how do you suggest an external system 'feed of' all transactions occuring?

pascallouis (Tue, 02 May 2017 20:11:28 GMT):
meanwhile, how do you suggest an external system 'feed of' all transactions occurring?

pascallouis (Tue, 02 May 2017 20:12:20 GMT):
we have a need to replicate some state in a local system, and basically record the before/after state in the operation result, and then replicate that

sstone1 (Tue, 02 May 2017 20:12:20 GMT):
There's not many options I'm afraid. You could build an application using the Fabric SDKs to subscribe to block events (which contain a list of Fabric transaction IDs).

pascallouis (Tue, 02 May 2017 20:13:08 GMT):
.... or wait for that historian component?

torresjeff (Tue, 02 May 2017 20:16:11 GMT):
thanks @sstone1

sstone1 (Tue, 02 May 2017 20:16:21 GMT):
or wait for the historian component :)

torresjeff (Tue, 02 May 2017 20:24:37 GMT):
@sstone1 by the way, will calling `connect()` before every chaincode invoke get around the issue?

sstone1 (Tue, 02 May 2017 20:24:58 GMT):
it will, because it will recreate the event hub connection

torresjeff (Tue, 02 May 2017 20:25:19 GMT):
that takes plenty of time right?

torresjeff (Tue, 02 May 2017 20:29:28 GMT):
would you suggest getting all the registries on application startup? if i add an asset for, say an asset registry, am I able to get the new asset if i got the registry at application startup or do i have to call `getAssetRegistry()` again to be able to see the new asset?

sstone1 (Tue, 02 May 2017 20:42:07 GMT):
it's not going to be particulary efficient - but if you're submitting enough transactions for it to be a problem, the event hub timeout won't be a problem

sstone1 (Tue, 02 May 2017 20:42:15 GMT):
you only have to get the asset registry once

torresjeff (Tue, 02 May 2017 20:43:19 GMT):
@sstone1 thank you very much

pascallouis (Tue, 02 May 2017 21:31:50 GMT):
@sstone1 about that transactionality... I still see part of the work in my handler occurring, while another part fails

pascallouis (Tue, 02 May 2017 21:32:13 GMT):
namely some objects get modified, and yet, another part of the handler fails

pascallouis (Tue, 02 May 2017 21:32:50 GMT):
could it be because I'm doing `getAssetRegistry` calls within the handler? doing this twice, for two different assets

dselman (Tue, 02 May 2017 21:34:53 GMT):
@sstone1 could @cassolato wrap his code in a domain, and reconnect / retry? Or perhaps use the ```process.on('uncaughtException', function(err) { // handle the error safely console.log(err) })``` handler?

@torresjeff Sorry for the delay trying now

@tennenjl thanks! gotta check why it doesn't work for me

torresjeff (Tue, 02 May 2017 22:02:48 GMT):
can you try with the `carauction-network.bna`?

https://composer-playground.mybluemix.net

torresjeff (Tue, 02 May 2017 22:06:25 GMT):
authenticate with github and import the `carauction-network` sample

torresjeff (Tue, 02 May 2017 22:07:03 GMT):
export the sample and try to deploy it

ok

thanks @tennenjl , @dselman @sstone1 what could be the cause of this error?

torresjeff (Tue, 02 May 2017 22:17:37 GMT):
seems to happen only with `carauction-network`

torresjeff (Tue, 02 May 2017 22:18:10 GMT):
@tennenjl though from what @sstone1 said earlier, it may be the connection hub

Just noticed the global `query` chaincode function in some unit tests. Is this something that works in 0.6 or does it require the new database backends in Hyperledger 1.0?

dselman (Wed, 03 May 2017 06:36:09 GMT):
It is work in progress (just design), but will require HLFv1 with CouchDB.

pospi (Wed, 03 May 2017 08:34:02 GMT):
OK thanks for letting me know :)

pospi (Wed, 03 May 2017 08:42:38 GMT):
hrm. Are there any plans to support transaction relationships? I would like to be able to relate an asset to some transactions but the model parser tells me `Relationship transactions must be to an asset or participant`

abcoathup (Wed, 03 May 2017 09:19:03 GMT):
I am using hlfv1, I generated a REST API and attempted to submit a transaction (creating Assets was fine) using curl on the command line and got the following error: {"error":{"statusCode":500,"name":"Error","message":"SyntaxError: parse error (line 49)","code":2,"metadata":{"_internal_repr":{}},"stack":"Error: SyntaxError: parse error (line 49)\n at /home/tss/.nvm/versions/node/v6.9.5/lib/node_modules/composer-rest-server/node_modules/fabric-client/node_modules/grpc/src/node/src/client.js:434:17"}} I don't know if this is an issue with my transaction processing code (which works in playground) or with something else

sstone1 (Wed, 03 May 2017 09:21:50 GMT):
@abcoathup are you using HLF v1.0 ?

abcoathup (Wed, 03 May 2017 09:22:16 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=M5GyET5TmvFxsR2Ab) @sstone1 Simon, just changed to HLFV1

sstone1 (Wed, 03 May 2017 09:22:44 GMT):
have you got any `let`, `const`, or `() => { }` arrow functions in your transaction processor functions?

sstone1 (Wed, 03 May 2017 09:23:28 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=3LHhZgxHGMm2BMExf) @pascallouis do you see this behaviour in the playground or when running against a real HLF instance?

abcoathup (Wed, 03 May 2017 09:24:09 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=FXNbTCo5QXowwmtZZ) @sstone1 yes, I have let

sstone1 (Wed, 03 May 2017 09:25:30 GMT):
the Golang JavaScript interpreter we use on HLF only supports ES5, so doesn't support `let`, `const`, or arrow functions

abcoathup (Wed, 03 May 2017 09:26:15 GMT):

@dselman I wonder if we could identify ES6/ES7 features using Acorn?

sstone1 (Wed, 03 May 2017 09:27:14 GMT):
the docs have a related setting: >>> ecmaVersion: Indicates the ECMAScript version to parse. Must be either 3, 5, 6 (2015), 7 (2016), or 8 (2017). This influences support for strict mode, the set of reserved words, and support for new syntax features. Default is 7.

@AlexKim yes, I think that should work

sstone1 (Wed, 03 May 2017 18:29:08 GMT):
if you start another instance of `composer-ui` and point it at the same fabric, it should connect to the same business network

Did you have an existing Fabric running before you ran `npm install` or `npm test` ?

I think there's a bug in the getting started script that fails to work properly if you have existing Docker containers running

possible. i started running a local version of this, and had issues. I thought this was the "easier" way

sstone1 (Wed, 03 May 2017 19:05:39 GMT):
`docker ps -aq | xargs docker rm -f` will clean up all docker images, you can then re-run `npm install` and `npm test`

@sstone1 @AlexKim I would think that the only way for another user to access the same business network, is for that user to be added as a participant, and then an identity issued to that participant. Ref: An identity can be issued to a participant using either the API or the command line. Once an identity has been issued, the identity can then be used by the participant to interact with the business network in the context of that participant.

davidkel (Wed, 03 May 2017 20:03:44 GMT):
@jinvanstee Unfortunately it's not possible at this time to issue an identity on bluemix using the CLI. There is an issue raised about this at https://github.com/hyperledger/composer/issues/606

dselman (Wed, 03 May 2017 20:09:14 GMT):
@jinvanstee you only need to explicitly issue identities if you want to be able to identify your participants based on their Fabric credentials. If you are building a POC you could use a generic Fabric id/secret and submit transactions that contain a participant id. This will allow you to test all your logic (except ACLs).

jinvanstee (Wed, 03 May 2017 20:09:25 GMT):
is this only an issue with bluemix.. will it work on a local fabric, or fabric installed on LinuxONE

jinvanstee (Wed, 03 May 2017 20:09:51 GMT):
@davidkel

davidkel (Wed, 03 May 2017 20:14:48 GMT):
@jinvanstee It's down to how the membership services server is configured.

davidkel (Wed, 03 May 2017 20:16:03 GMT):
for example if you use the v0.6 docker images then their configuration has institution_a defined

jinvanstee (Wed, 03 May 2017 20:17:07 GMT):
i see @davidkel

cassolato (Wed, 03 May 2017 21:16:13 GMT):
@sstone1 some idea how to fix the event hub issue? using a different peer?

ZenX0904 (Thu, 04 May 2017 04:16:30 GMT):
Hi all, Anybody can provide me a link to start up fabric peer and membership service? The link here in the tutorial is dead https://hyperledger.github.io/composer/business-network/runtime-start.html

AlexKim (Thu, 04 May 2017 04:36:42 GMT):
@ZenX0904 are you looking for v0.6?

ZenX0904 (Thu, 04 May 2017 04:47:11 GMT):
@AlexKim Yes v0.6

ZenX0904 (Thu, 04 May 2017 04:47:24 GMT):
@AlexKim I'm running Ubuntu 16.04 LTS

AlexKim (Thu, 04 May 2017 05:05:07 GMT):
@ZenX0904 you can probably try this out

AlexKim (Thu, 04 May 2017 05:05:18 GMT):
@ZenX0904 https://github.com/IBM-Blockchain/fabric-images

AlexKim (Thu, 04 May 2017 05:06:09 GMT):
works with x86, ppc and s390x

ZenX0904 (Thu, 04 May 2017 05:07:01 GMT):
@AlexKim Great! Will try it out. Thanks!

AlexKim (Thu, 04 May 2017 05:07:19 GMT):
@ZenX0904 you're very welcome, good luck!

ZenX0904 (Thu, 04 May 2017 05:13:40 GMT):
@AlexKim Will I be able to deploy a business network to this? I'm following this tutorial currently https://hyperledger.github.io/composer/unstable/business-network/deploybusinessnetwork.html and it's not entirely clear with the steps... Do I need to create a connection profile? And what is my enrollment ID?

AlexKim (Thu, 04 May 2017 05:17:34 GMT):
@ZenX0904 yes it works with composer cli

AlexKim (Thu, 04 May 2017 05:18:35 GMT):
@ZenX0904 ID/Secret should be in the tutorials

AlexKim (Thu, 04 May 2017 05:19:15 GMT):
@ZenX0904 but if you want to test bna - you can install following on ubuntu - it's all inclusive including fabric(peer+membersvcs)

AlexKim (Thu, 04 May 2017 05:19:19 GMT):
@ZenX0904 https://hyperledger.github.io/composer/unstable/tutorials/getting-started-playground.html

ZenX0904 (Thu, 04 May 2017 05:22:21 GMT):
@AlexKim Yes I've just done that actually, installed composer playground on my local Ubuntu, because I'm really having a hard time figuring our the fabric network setup. Thanks for your help, guess I'll need to spend more time with the link you provided previously

AlexKim (Thu, 04 May 2017 05:22:48 GMT):
@ZenX0904 sure np

paul.sitoh (Thu, 04 May 2017 07:16:54 GMT):
Could you elaborate on the implications of deploying BNA to v1 as it is now?

davidkel (Thu, 04 May 2017 07:21:25 GMT):
@paul.sitoh we have experimental support in composer currently that allows to deploy to and interact with a hyperledger fabric runtime v1.0.0-alpha level. From a composer point of view there should be no difference between using a v0.6 vs a v1.0.0-alpha runtime. You need a different connection profile for connecting to a v1.0.0-alpha environment however.

paul.sitoh (Thu, 04 May 2017 07:29:14 GMT):
At this juncture I am not too concern about playground. Having it will not add value to most of my projects at this juncture. We can deal with command line for now. Main concern is how BNA deals with v1 concept of chaincode versioning. Chaincode instantiation. Channels, etc. How will I be able to migrate BNA deployed on fabric 1.0.0 to say 1.0.1 and not break because of things like versioning, etc. In other words, what does versioning mean in the context of BNA? What does chaincode instantation mean in BNA context?

paul.sitoh (Thu, 04 May 2017 07:37:08 GMT):
In Go chaincode, I can see if you do a peer deploy something happens. And instantiation of chaincode, means calling Init function. How does this work in composer BNA context?

dselman (Thu, 04 May 2017 08:54:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Qb6Xhfxc7b4smrMk7) @ZenX0904 run the Composer QuickStart -- it will start a simple v0.6 dev Fabric for you.

davidkel (Thu, 04 May 2017 10:15:40 GMT):
@paul.sitoh Composer needs to know the channel where the business network is to be deployed to or has been deployed to and that is stored in the connection profile. In HLF V1 there are 2 steps to getting chaincode executing. Step 1 is to install chaincode onto the peer. In the composer case the chaincode runtime is packaged and installed on the peer (it get's versioned with the version number of the composer runtime + the name of the business network archive). When the instantiate is called on the peer, composer passes the BNA to that runtime and as part of the init call the composer chaincode processes the Business Network Archive and initialises it.

gormand (Thu, 04 May 2017 10:58:22 GMT):
Hi @davidkel - Can you deploy more than one composer chaincode and BNA to the same channel?

davidkel (Thu, 04 May 2017 11:01:31 GMT):
Hi @gormand yes you can

gormand (Thu, 04 May 2017 11:01:50 GMT):
Thanks :slight_smile:

dselman (Thu, 04 May 2017 11:22:49 GMT):

paul.sitoh (Thu, 04 May 2017 11:44:27 GMT):
@davidkel one more question. How do we deal with endorsement policies with respect to composer?

davidkel (Thu, 04 May 2017 11:45:57 GMT):
@paul.sitoh composer doesn't do anything with endorsement policies. It's an area I really want to get a better understand of

jinvanstee (Thu, 04 May 2017 13:56:28 GMT):
Is there a composer CLI to add an asset? say for the car auction network, to add a car? is that considered a transaction? and I'd use the composer transaction submit command?

gormand (Thu, 04 May 2017 14:15:09 GMT):
Hi @davidkel , Does composer currently support multiple endorsers in v1? Is it possible to call multiple endorsers for endorsement, before the transaction is sent for ordering by the ordering-service?

davidkel (Thu, 04 May 2017 14:18:00 GMT):
Hi @gormand yes, you can send txn proposals to multiple peers for endorsement. Currently all are expected to respond and we don't perform any checks on the response before sending the txn to the ordering service

kletkeman (Thu, 04 May 2017 14:25:10 GMT):
@davidkel Presumably, composer will one day support endorsement policies that will be enforced, yes?

jinvanstee (Thu, 04 May 2017 14:30:38 GMT):
I suppose this is a futures question...since the composer playground is still only a playground. I know you can use the composer CLI and APIs to modify, add assets to, etc. an existing deployed network, will I be able to use the composer-ui to manage/modify an already deployed network?

jinvanstee (Thu, 04 May 2017 14:32:14 GMT):
BTW I just really want to thank you guys for answering questions..pretty much around the clock... I really want to showcase this tool at a client blockchain workshop on May 17th.

davidkel (Thu, 04 May 2017 14:35:29 GMT):
@kletkeman I am sure we will look to exploit facilities such as instantiate and endorsement policies in the future for composer

jeffgarratt (Thu, 04 May 2017 14:40:02 GMT):
@kletkeman the latest fabric master branch enforces endorsement policies already... so enforcement is no long an option. Exposure to and configuration of these policies (which are in general defaulted to reasonable settings) is what is forthcoming.

jeffgarratt (Thu, 04 May 2017 14:40:02 GMT):

jeffgarratt (Thu, 04 May 2017 14:41:03 GMT):
and by master, I mean fabric master :)

kletkeman (Thu, 04 May 2017 14:41:11 GMT):
@jeffgarratt Excellent. I was getting worried with so much basic wiring pushed out to client code and was hoping for a thicker SDK layer. Doing reasonable defaults inside Fabric itself is even better.

davidkel (Thu, 04 May 2017 14:43:41 GMT):
Hi @jeffgarratt I was actually trying to quantify what those defaults were. I asked a question ob #fabric-crypto regarding the default for endorsement policy but you might know the answer ? The docs state the default is `the default policy requires one signature from a member of the DEFAULT MSP` but I don't know what the default MSP is

jeffgarratt (Thu, 04 May 2017 14:44:38 GMT):
@davidkel @kletkeman the default policy may differ slightly by the mechanism you use to create (boostrap) the system.

jeffgarratt (Thu, 04 May 2017 14:44:38 GMT):
@davidkel @kletkeman the default policy may differ slightly by the mechanism you use to create (bootstrap) the system.

jeffgarratt (Thu, 04 May 2017 14:45:18 GMT):
and there is a default endorsement policy that is enabled if one is not provided on deployment

kletkeman (Thu, 04 May 2017 14:45:27 GMT):
Yes, as I recall, a fair bit of configuration info is stored in the genesis block

jeffgarratt (Thu, 04 May 2017 14:46:06 GMT):
@kletkeman correct... And this can be generalize to all information is stored in the config_update block (which the genesis is of course one of)

jeffgarratt (Thu, 04 May 2017 14:46:06 GMT):
@kletkeman correct... And this can be generalized to all information is stored in the config_update block (which the genesis is of course one of)

kletkeman (Thu, 04 May 2017 14:47:07 GMT):
@jeffgarratt Cool, thanks. Is the default endorsement all endorsers respond plus all R/W equivalent?

jeffgarratt (Thu, 04 May 2017 14:48:38 GMT):
I will assemble a more coherent answer to your question asap

kletkeman (Thu, 04 May 2017 14:48:58 GMT):
Thanks.

jeffgarratt (Thu, 04 May 2017 14:49:04 GMT):
as that differs per bootstrap mechanism (e2e vs behave)

jeffgarratt (Thu, 04 May 2017 14:49:04 GMT):
as that may possible differ per bootstrap mechanism (e2e vs behave)

jeffgarratt (Thu, 04 May 2017 14:49:24 GMT):
yw

jeffgarratt (Thu, 04 May 2017 14:49:48 GMT):
this is a point of clarification the community is actively working on (myself included)

jeffgarratt (Thu, 04 May 2017 14:50:36 GMT):
@davidkel and I owe this answer to you as well

kletkeman (Thu, 04 May 2017 14:51:02 GMT):
I'll have to go and look up the difference between e2e and behave as they apply to bootstrap ...

davidkel (Thu, 04 May 2017 14:51:16 GMT):
Thanks Jeff, that would be great. Would the same concepts also apply to instantiate policy ?

kletkeman (Thu, 04 May 2017 14:53:56 GMT):
Only e2e is mentioned along with bootstrap, behave is missing from the docs: http://hyperledger-fabric.readthedocs.io/en/latest/getting_started.html?highlight=bootstrap

bestbeforetoday (Thu, 04 May 2017 15:55:19 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=M6iQbpKivCfajFk6N) @jinvanstee No CLI to add an asset (yet). You can add assets using the JavaScript API, or Loopback-generated REST API. You could also write a transaction that caused an asset to be created and invoke that if it made sense for your business scenario. There is a GitHub issue to capture a (not yet implemented) requirement to bulk load assets, which I guess would likely be command-line driven: https://github.com/hyperledger/composer/issues/769

jinvanstee (Thu, 04 May 2017 15:58:04 GMT):
thanks @bestbeforetoday .. I was just looking at the APIs and they have everything I'm looking for .. argh I'm not a great JavaScript developer

bestbeforetoday (Thu, 04 May 2017 16:04:26 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=A7JGgomuqbt2QDGtF) @jinvanstee Once the Playground UI has functionality to configure different connection profiles, the UI will be able to view / add / modify resources in whatever network it is connected to. This should be coming real soon now

jinvanstee (Thu, 04 May 2017 16:07:15 GMT):
@bestbeforetoday That would be really great!! The issue I'm finding with the old composer-ui is that I can't use it to connect to an existing network because there's nowhere to specify the chaincode ID. It ends up just deploying another network to my fabric.

jinvanstee (Thu, 04 May 2017 16:07:43 GMT):

@dselman @bestbeforetoday I have an existing network on my blueMix fabric that I would like to connect to, using the unstable playground... I imported my connection profile .. where do I specify which chain I want to connect to? I have multiple chains on my fabric (V0.6). second question can I use an existing id/secret, or do I need to use a new one?

@jinvanstee you cannot use http://composer-playground-unstable.mybluemix.net to connect to a real Hyperledger Fabric instance, this is only supported locally... just fixing an issue which will remove connection profiles from the cloud hosted version.

ZenX0904 (Thu, 04 May 2017 19:07:09 GMT):
@dselman Thanks! That worked perfectly fine. What if I wanted to add more nodes?

sstone1 (Thu, 04 May 2017 19:08:45 GMT):
@ZenX0904 Composer won't do that for you, you'll need to configure and deploy a Fabric instance with the required number of nodes. Composer's getting started guide simply creates a minimal Fabric configuration that can be used to test out Composer functionality.

ZenX0904 (Thu, 04 May 2017 19:14:08 GMT):
@sstone1 Thanks!

jinvanstee (Thu, 04 May 2017 19:33:53 GMT):
So I've moved onto generating an Angular2 app using the fabric-composer generator, connecting to a running business network. I'm able to see all my assets, and add an asset, and see it committed as a block on the chain. Is there a way to generate the modules needed to view/add participants, and to submit and view transactions? :)

sstone1 (Thu, 04 May 2017 19:34:17 GMT):
Afraid not :( there is some pending work to add participants and transactions... hang on let me find the GitHub

ZenX0904 (Fri, 05 May 2017 08:20:14 GMT):
Hi, Can anyone guide me how to I add assets onto a composer network using the command line? I've added the participants but no idea how to do the same assets. Tried searching the documentations but no results. Thanks!

sstone1 (Fri, 05 May 2017 08:21:05 GMT):
@ZenX0904 there is not currently a CLI command to add an asset

ZenX0904 (Fri, 05 May 2017 08:21:47 GMT):
@sstone1 so right now it's only possible through the browser playground?

sstone1 (Fri, 05 May 2017 08:22:03 GMT):
or using the Node.js APIs in the `composer-client` module

sstone1 (Fri, 05 May 2017 08:22:13 GMT):
or using the REST APIs created by the `composer-rest-server` app

ZenX0904 (Fri, 05 May 2017 08:22:50 GMT):
ok I'll try out the Node.js approach. Thanks!

sstone1 (Fri, 05 May 2017 08:26:10 GMT):
np :)

sstone1 (Fri, 05 May 2017 08:27:08 GMT):
@here today we will be aiming to cut the v0.7.1 release of Composer which will add connection profile + identity support to the Playground, meaning you can locally install Playground and connect it to a real Fabric v0.6 or Fabric v1.0!

sstone1 (Fri, 05 May 2017 08:29:05 GMT):
Before we cut each release we go through this guide to test that the tutorials/getting started guide and playground are working as expected: https://github.com/hyperledger/composer/blob/master/contrib-notes/weekly-qa-validation.md

sstone1 (Fri, 05 May 2017 08:30:52 GMT):
We will also be removing the old UI, `composer-ui`, because the playground now includes all of the functionality that was present. You will still be able to install it from npm or Docker Hub, but it will no longer receive any updates.

davidkel (Fri, 05 May 2017 10:39:29 GMT):
@uber.twin can you give some details of your environment ? such as operating system, docker & docker-compose version ?

uber.twin (Fri, 05 May 2017 11:22:08 GMT):
@davidkel Ubuntu 16.04.2 LTS Docker version 17.03.1-ce docker-compose version 1.13.0

nvlasov (Fri, 05 May 2017 11:24:54 GMT):
@here Guys, is there any guide on how to pass errors from chaincode's transactions to the client, who requested it? I tried two ways to submit transaction: REST server and composer command line. If transaction was executed successfully, I'm getting an updated member/asset object in REST server and "Command completed successfully." message in the command line. If transaction was not successful (i.e. triggered error by "trow new Error("PANIC!!!")" ), both REST server and composer command line just hangs and does not return anything, as if it takes very long to execute transaction. Technically I can wait for some timeout, return an error that something went wrong and ask user to re-send transaction. But is there any way to pass error message from chaincode to the client?

uber.twin (Fri, 05 May 2017 11:26:58 GMT):
@davidkel the "hosts" file of my "peer0" container does not have a "orderer0" entry

jorgedr (Fri, 05 May 2017 11:27:09 GMT):
Hi @nvlasov are you using Fabric v0.6? My understanding is that there was a problem with v0.6 that causes failed transactions to hang. I Have experienced the same thing. This problems is supposed to be fixed in v1.0

nvlasov (Fri, 05 May 2017 11:29:54 GMT):
@jorgedr Yes, I'm on Fabric v0.6, but I see in the chaincode's log that it's actually handled exception correctly and sends error message to the log. The thing is that it does not return anything back to the client for Invoke transactions.

nvlasov (Fri, 05 May 2017 11:36:25 GMT):
So I was hoping Composer will do some magic and communicate chaincode's error message back. Which doesn't seems to happen. Is it a limitation of Fabric 0.6 protocol?

davidkel (Fri, 05 May 2017 11:57:46 GMT):
@uber.twin I had problems with docker-compose 1.12, not tried 1.13 but I know that 1.11 does work so might be worth downgrading to that version

uber.twin (Fri, 05 May 2017 13:30:29 GMT):
@davidkel it doesn't seem to help. I just checked the CLI peer logs in the Fabric v1 corresponding setup and it seems to contain the same kind of error

uber.twin (Fri, 05 May 2017 13:31:06 GMT):
but it doesn't mind it

uber.twin (Fri, 05 May 2017 13:31:37 GMT):
there it doesn't seem like a critical error

bestbeforetoday (Fri, 05 May 2017 13:39:41 GMT):
@uber.twin So even though you see some error messages, things work with Docker Compose 1.11 but fail with Docker Compose 1.13?

uber.twin (Fri, 05 May 2017 13:47:44 GMT):
no, the error appears, no matter which docker compose I use

uber.twin (Fri, 05 May 2017 13:48:59 GMT):
and it is manifesting in the Hyperledger Fabric tutorial also

uber.twin (Fri, 05 May 2017 13:49:22 GMT):
it just doesn't seem to be critical in the context of Hyperledger Fabric getting started tutorial

uber.twin (Fri, 05 May 2017 13:51:13 GMT):
in there, even though this error appears, the CLI peer can carry on all the operations(create and join a channel, install, instantiate and invoke the chaincode)

uber.twin (Fri, 05 May 2017 13:52:48 GMT):
while in Hyperledger Composer context, it causes the demo to halt

davidkel (Fri, 05 May 2017 14:06:14 GMT):
@uber.twin It sounds like a networking issue which is managed by docker compose. Can I confirm this is what you see when you start up the v1 alpha images ``` Creating network "hlfv1_default" with the default driver Creating ca_peerOrg1 Creating orderer0 Creating peer0 Creating peer1 ``` Note the network name that is created. It must be hlfv1_default

uber.twin (Fri, 05 May 2017 14:14:54 GMT):
@davidkel yes, precisely like that

davidkel (Fri, 05 May 2017 14:19:06 GMT):
@uber.twin how about `sudo netstat -nlp | grep 705` ?

davidkel (Fri, 05 May 2017 15:23:37 GMT):
@uber.twin not sure what the problem is with your docker containers whether they have some sort of problem doing namespace resolving or whether there is some sort of network blocking going on. If you have a firewall, can you try disabling it to see if it is affecting the network

sstone1 (Fri, 05 May 2017 18:13:04 GMT):
@here we've released Hyperledger Composer v0.7.1, read all about it on GitHub: https://github.com/hyperledger/composer/releases/tag/v0.7.1 :tada:

sstone1 (Fri, 05 May 2017 18:13:35 GMT):
It includes the feature you have all been waiting for - connection profiles and identity management in the playground - so you can use the playground to connect to a real Hyperledger Fabric instance!

sstone1 (Fri, 05 May 2017 18:13:47 GMT):
It supports Hyperledger Fabric v0.6 and v1.0 alpha.

@sstone1 Awesome!

AlexKim (Fri, 05 May 2017 19:03:48 GMT):
@sstone1 @dselman we'll test asap ! is there a way to point to a specific network id with it? or is it same as composer - ui?

dselman (Fri, 05 May 2017 20:21:30 GMT):
The connections are all driven via connection profiles -- so you can deploy a BNA, then export the connection profile and give it to someone else and connect.

@dselman great! thanks so much !!

Hi, I imported my `connection.json` file into the new composer playground locally, but i get an error: `Failed to connect: Error: ENOENT: no such file or directory, mkdir '/home/jeff/.composer-credentials/bluemix1'`, this is the same directory I've been using with the old-composer ui to store my certificates. Right now I have a file named `member.admin` in that folder, but composer playground apparently doesn't find the folder

torresjeff (Sat, 06 May 2017 03:02:58 GMT):
has anyone had a similar problem?

dselman (Sat, 06 May 2017 08:03:20 GMT):
@torresjeff because Playground is running inside a Docker container, that file path is relative to the storage connected to the Docker container. You should use `/home/composer/.composer-credentials` when running with Docker. If you are running Playground on the local machine (using `npm start`) then the file path will be your local disk.

tennenjl (Sat, 06 May 2017 13:58:49 GMT):
Hi there, we have an abstract transaction which is then extended by other abstract transactions which then are extended by concrete transactions. However, when we try to work with this using the playground, the playground throws an error - Error: No concrete extending type for myNameSpace.MyAbstractTransaction

Thanks @dselman

torresjeff (Sat, 06 May 2017 15:21:02 GMT):
@dselman is there any difference performance wise between the docker version and the npm version?

sstone1 (Sat, 06 May 2017 15:21:51 GMT):
@torresjeff nope, should be no difference between the two

torresjeff (Sat, 06 May 2017 15:22:03 GMT):
@sstone1 thanks!

torresjeff (Sat, 06 May 2017 15:22:23 GMT):
btw simon, is there an expected date where they fix the event hub connection issue?

torresjeff (Sat, 06 May 2017 15:26:31 GMT):
was this fixed in v1?

sstone1 (Sat, 06 May 2017 15:28:45 GMT):
It won't be fixed in v0.6. I asked the Fabric team the other day about v1.0, it's still not fixed but definitely on their radar.

torresjeff (Sat, 06 May 2017 15:29:18 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=LwKnxkdBNc9iRmhYv) @tennenjl sounds like a bug. Playground is not finding your concrete transactions. Can you please open an issue and attach your BNA and I will debug.

tennenjl (Sat, 06 May 2017 21:05:57 GMT):
@dselman Thanks. Will do. Thanks!

shsedghi (Sun, 07 May 2017 01:20:59 GMT):
@dselman I have created a tool that takes a JSON payload and creates a cto model (concept for now) has been tested with many payloads but may need feeed back from community to improve. it in IBM github now at https://github.ibm.com/ssedghi/json-to-cto, I can present it at a call and move it to a public one.

tennenjl (Sun, 07 May 2017 03:06:43 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=MSycxynghttXJ96k5) @dselman Actually, now that I have done some more digging, I don't think it is a bug, its a problem that sstone1 actually helped me with in the past, where I have an asset which contains an abstract transaction. Sorry for the false alarm!

tennenjl (Sun, 07 May 2017 03:16:32 GMT):
OK, so just so I understand, when we create an asset definition, can it contain an optional abstract transaction like an interface or can I only have an asset definition contain concrete types. For example, in my asset, I want it to contain an optional array of transactions, in this case it sounds like I can't have an array of the the abstract transaction type and instead have to create multiple array definitions for each concrete transaction type which extends the abstract transaction type?

dselman (Sun, 07 May 2017 08:22:42 GMT):
Assets should be able to contain abstract transactions. Can you send me your model?

@tennenjl thanks -- I have reproduced the bug.

dselman (Sun, 07 May 2017 20:44:56 GMT):
I think one of the issues is that NATransaction is abstract.

dselman (Sun, 07 May 2017 20:45:01 GMT):
``` abstract transaction NATransaction extends GeoTransaction { o SampleAsset myAsset } ```

dselman (Sun, 07 May 2017 20:45:28 GMT):
I.e. there is no concrete class that extends GeoTransaction that can be instantiated.

dselman (Sun, 07 May 2017 20:45:53 GMT):
I also think that `o SampleAsset myAsset` should be `--> SampleAsset myAsset`

dselman (Sun, 07 May 2017 20:46:59 GMT):
When I make these changes I am able to create an instance of SampleAsset and generate random data...

dselman (Sun, 07 May 2017 20:47:06 GMT):
``` { "$class": "org.acme.sample.SampleAsset", "assetId": "assetId:1738", "owner": "resource:org.acme.sample.SampleParticipant#participantId:8421", "value": "cause", "transactions": [ { "$class": "org.acme.sample.NATransaction", "myAsset": "resource:org.acme.sample.SampleAsset#assetId:7718", "transactionId": "transactionId:7827", "transactionLocation": { "$class": "org.acme.sample.GeoLocation", "latitude": 120.278, "longitude": 126.002 }, "timestamp": "2017-05-07T20:46:28.082Z" }, { "$class": "org.acme.sample.NATransaction", "myAsset": "resource:org.acme.sample.SampleAsset#assetId:7857", "transactionId": "transactionId:0029", "transactionLocation": { "$class": "org.acme.sample.GeoLocation", "latitude": 65.676, "longitude": 173.831 }, "timestamp": "2017-05-07T20:46:28.082Z" }, { "$class": "org.acme.sample.NATransaction", "myAsset": "resource:org.acme.sample.SampleAsset#assetId:6690", "transactionId": "transactionId:3801", "transactionLocation": { "$class": "org.acme.sample.GeoLocation", "latitude": 22.986, "longitude": 150.434 }, "timestamp": "2017-05-07T20:46:28.082Z" } ] } ```

``` not sure what the problem is with your docker containers whether they have some sort of problem doing namespace resolving or whether there is some sort of network blocking going on. If you have a firewall, can you try disabling it to see if it is affecting the network ```

dselman (Mon, 08 May 2017 15:34:48 GMT):
the `--` option if for the full name, the `-` option is the short name.

You can use either

uber.twin (Mon, 08 May 2017 15:36:50 GMT):

not -n

sstone1 (Mon, 08 May 2017 15:39:35 GMT):
@GururajL here is the one line script installer I've been working on. Would appreciate any feedback you might have! Before you run the command, make sure any running containers are removed by running: `docker ps -aq | xargs docker rm -f` You can then start the one line installer by running: `curl -O https://gist.githubusercontent.com/sstone1/1bf44bc8697f2c59bcdfc30b42c9d8c9/raw/4b75d8835b9f9efbd8c4810f610bc89f7b24f03e/setup.sh && bash setup.sh` If anyone else wants to try it great, but it probably only works on Mac :)

davidkel (Mon, 08 May 2017 15:53:14 GMT):
@vinitesh There are a couple of ways to get around the problem for now. You either need to remove all the \r\n text from the text before putting into the cert field on the UI, or you can import your current connection profile which you use for connection via the command line

dselman (Mon, 08 May 2017 15:54:16 GMT):
@vinitesh that would be a good StackOverflow question and answer... Can you post it please?

jje (Mon, 08 May 2017 15:54:19 GMT):
and an asset definition asset Product identified by GTIN{ o String GTIN o String ProductName o Boolean commissioned optional --> Manufacturer company } and then I create manufacturers GLN:1 and GLN:2. If I know create a product GTIN:3 { "$class": "net.biz.PropertyNetwork.Product", "GTIN": "GTIN:3", "ProductName": "wabvi", "commissioned": false, "company": "resource:net.biz.PropertyNetwork.Manufacturer#GLN:5038" } it happily accepts the manufacturer GLN:5038. There is apparently no relationship checking. Only when I try to do a transaction it actually comes back and says that GLN:5038 doesn't exist. I would have expected this check already at asset creation time. Is this intended behavior or how can I change this to do the relationship checking at asset creation time already?

dselman (Mon, 08 May 2017 15:55:37 GMT):
@jje no, there's no referential integrity in Composer -- however prior to processing transactions the runtime attempts to resolve relationships.

dselman (Mon, 08 May 2017 15:56:05 GMT):
You should write your business logic to tolerate relationships that fail to resolve.

jje (Mon, 08 May 2017 15:56:33 GMT):
OK, I understand, good to know. Thanks for the quick reply!

sstone1 (Mon, 08 May 2017 16:14:27 GMT):

FYI: as I just posted in composer-dev, I couldn't see this channel up until 5 min ago. I restarted rocketchat and now I can see composer. Not sure if it was the restart or maybe something else. I'm now able to see #composer (obviously :-)

torresjeff (Mon, 08 May 2017 16:55:09 GMT):
@dselman is there anything equivalent to AssetRegistry but for concepts?

dselman (Mon, 08 May 2017 16:55:17 GMT):
no

dselman (Mon, 08 May 2017 16:55:28 GMT):
you should wrap them in an asset

torresjeff (Mon, 08 May 2017 16:55:36 GMT):
ok thanks

sstone1 (Mon, 08 May 2017 16:57:44 GMT):
@stu2 there's a problem that needs a rocketchat server upgrade which is in hand :)

vinitesh (Mon, 08 May 2017 16:58:47 GMT):
Thanks @davidkel . Importing the connection profile takes me one step further. Now i am getting the following error 0|composer | HLFConnection :queryChainCode() Received 2 payloads(s) from querying the chaincode [{"code":2,"metadata":{"_internal_repr":{}}},{"code":2,"metadata":{"_internal_repr":{}}}] 0|composer | HLFConnection :queryChainCode() Error: failed to obtain cds for org.acme.biznet - transaction not found org.acme.biznet/ServicePartnerChannel 0|composer | HLFConnection :ping() Error: failed to obtain cds for org.acme.biznet - transaction not found org.acme.biznet/ServicePartnerChannel 0|composer | ConnectorServer :Error: failed to obtain cds for org.acme.biznet - transaction not found org.acme.biznet/ServicePartnerChannel() undefined 0|composer | ConnectorServer :connectionPing() <

vinitesh (Mon, 08 May 2017 16:59:54 GMT):
'ServicePartnerChannel' is name of the channel in blockchain service and 'org.acme.biznet' is no where in my network namespace

davidkel (Mon, 08 May 2017 17:01:12 GMT):
@vinitesh I know some fixes went in over the weekend I don't know if they resolve this problem but just to be sure, when did you pull the docker image ?

vinitesh (Mon, 08 May 2017 17:02:11 GMT):
@davidkel this morning

sstone1 (Mon, 08 May 2017 17:02:55 GMT):
@vinitesh you need to pull the unstable image to fix that problem

vinitesh (Mon, 08 May 2017 17:04:44 GMT):
@sstone1 what is the tag for that image?

GururajL (Mon, 08 May 2017 17:05:22 GMT):
@sstone1 , i hv some general questions, 1. Does one composer app correspond to one block chain/one channel on the network? 2. How to add peers dynamically to an existing channel/block chain?

torresjeff (Mon, 08 May 2017 17:06:03 GMT):
I imported my connection profile using my `connection.json` on my machine (running composer playground through npm), now I'm getting the following error: `Error: Error: Input parameter missing`

GururajL (Mon, 08 May 2017 17:06:26 GMT):
3. if one composer app corresponds to one channel, how to specify which channel to deploy this composer app on?

davidkel (Mon, 08 May 2017 17:06:53 GMT):
@vinitesh the tag name is 'unstable'

davidkel (Mon, 08 May 2017 17:08:59 GMT):
@GururajL You deploy a business network to a specifed channel. That channel is defined in a connection profile which you create to define your fabric I would suggest asking point 2 on the #fabric-questions channel

torresjeff (Mon, 08 May 2017 17:09:13 GMT):
I don't know if it's a bug or if its the intended behavior, but whenever i get an error in the playground I can no longer switch connection profile

torresjeff (Mon, 08 May 2017 17:09:32 GMT):
the icon of connection profiles swithces to `Get local version`

sstone1 (Mon, 08 May 2017 17:09:59 GMT):
@vinitesh the tag is unstable; `docker pull fabriccomposer/composer-playground:unstable`

Team has anyone seen 502 Gateway errors when running fabric client in Bluemix?

torresjeff (Mon, 08 May 2017 17:23:10 GMT):
@tennenjl probably due to the event hub issue?

tennenjl (Mon, 08 May 2017 17:24:02 GMT):
@torresjeff, Thanks I'm wondering if I can validate that

torresjeff (Mon, 08 May 2017 17:25:51 GMT):

torresjeff (Mon, 08 May 2017 18:50:24 GMT):
@tennenjl what was it?

torresjeff (Mon, 08 May 2017 18:52:12 GMT):
@tennenjl so have you been able to circumvent the event hub issue?

tennenjl (Mon, 08 May 2017 18:53:21 GMT):
@torresjeff We're still connecting and disconnecting for each api call.

torresjeff (Mon, 08 May 2017 18:53:53 GMT):
@tennenjl how long does it take on average to complete a transaction?

tennenjl (Mon, 08 May 2017 18:54:29 GMT):
@torresjeff a few seconds, haven't been doing any real testing

torresjeff (Mon, 08 May 2017 18:54:57 GMT):
@tennenjl one more question, sorry to bother you so much, if you restart your app you have to enroll with different credentials right?

torresjeff (Mon, 08 May 2017 18:55:10 GMT):
or are you saving the certificate in a database?

tennenjl (Mon, 08 May 2017 18:56:45 GMT):
@torresjeff Not bothering me at all, we're all here to help. We save the credentials in the project right now (since it's just a poc), but I need to look at the new wallet apis

torresjeff (Mon, 08 May 2017 18:57:42 GMT):
@tennenjl could you point me to documentation about the wallet?

can't seem to find anything about it in the jsdoc

torresjeff (Mon, 08 May 2017 18:58:06 GMT):
https://hyperledger.github.io/composer/jsdoc/index.html

sstone1 (Mon, 08 May 2017 18:58:23 GMT):
it's not particularly well documented

sstone1 (Mon, 08 May 2017 18:58:54 GMT):
@tennenjl is waiting for me to document it ;)

torresjeff (Mon, 08 May 2017 18:59:22 GMT):
@sstone1 ok, thanks!

torresjeff (Mon, 08 May 2017 18:59:32 GMT):
is the wallet something that is stored in the fabric instance as well?

tennenjl (Mon, 08 May 2017 18:59:51 GMT):
:laughing: but you can find source here I believe https://hyperledger.github.io/composer/jsdoc/composer-common_lib_wallet.js.html

torresjeff (Mon, 08 May 2017 19:00:49 GMT):
@tennenjl thanks!

sstone1 (Mon, 08 May 2017 19:01:03 GMT):
the wallet is purely client side and manages the persistence of identities (for fabric, that's enrolment certificates)

torresjeff (Mon, 08 May 2017 19:01:19 GMT):
lol throw throw throw

torresjeff (Mon, 08 May 2017 19:01:43 GMT):
@sstone1 ok, will be waiting for some documentation ;)

sstone1 (Mon, 08 May 2017 19:01:57 GMT):
how about a _possibly_ working example?

sstone1 (Mon, 08 May 2017 19:02:00 GMT):
https://github.com/sstone1/sample-bluemix-composer-app

sstone1 (Mon, 08 May 2017 19:02:34 GMT):
sorry it's bluemix specific - but in the `lib` folder you'll find a wallet implementation that stores identities in the bluemix object storage service

torresjeff (Mon, 08 May 2017 19:02:55 GMT):
@sstone1 that works, using bluemix anyway :)

sstone1 (Mon, 08 May 2017 19:03:09 GMT):
in `app.js` you'll see how to use the wallet in combination with the client APIs: ``` const wallet = new ObjectStorageWallet(container); return businessNetworkConnection.connect(connectionProfileName, businessNetworkIdentifier, userID, userSecret, { wallet: wallet }) ```

torresjeff (Mon, 08 May 2017 19:03:16 GMT):
thanks a lot

torresjeff (Mon, 08 May 2017 19:04:23 GMT):
@sstone1 do you think we could see a comparison of a composer app vs a pure hyperledger one? will someone be doing something like that?

torresjeff (Mon, 08 May 2017 19:04:53 GMT):
composer has helped me clear a lot of things up about hyperledger fabric

torresjeff (Mon, 08 May 2017 19:05:18 GMT):
but would still like to see how things are handled differently using the sdk for fabric

tennenjl (Mon, 08 May 2017 19:05:59 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=dj4NqtJ2W2emAz8QX) @sstone1 TY :-)

sstone1 (Mon, 08 May 2017 19:06:00 GMT):
i'm not aware of anyone doing that

sstone1 (Mon, 08 May 2017 19:06:16 GMT):
np @tennenjl sorry it took a while! give me a shout if you have any problems

torresjeff (Mon, 08 May 2017 19:21:53 GMT):
@sstone1 what exactly are you storing in the OBJECT_STORAGE_CONTAINER env variable?

sstone1 (Mon, 08 May 2017 19:22:10 GMT):
the name of the Object Storage Container ;)

sstone1 (Mon, 08 May 2017 19:22:35 GMT):
in this case, "Composer Wallet"

sstone1 (Mon, 08 May 2017 19:22:47 GMT):
Object Storage lets you partition the data into named containers

torresjeff (Mon, 08 May 2017 19:22:57 GMT):
oh ok

torresjeff (Mon, 08 May 2017 19:22:59 GMT):
thank you

sstone1 (Mon, 08 May 2017 19:23:00 GMT):
some of the env vars used are here: https://github.com/sstone1/sample-bluemix-composer-app/blob/master/manifest.yml

torresjeff (Mon, 08 May 2017 19:23:12 GMT):
perfect

torresjeff (Mon, 08 May 2017 19:23:19 GMT):

sstone1 (Mon, 08 May 2017 19:23:22 GMT):
np

torresjeff (Mon, 08 May 2017 19:24:03 GMT):
@sstone1 is there any difference in using COMPOSER_CONFIG: | or COMPOSER_CONFIG: > ?

sstone1 (Mon, 08 May 2017 19:24:56 GMT):
> replaces newlines with spaces, | preserves newlines

sstone1 (Mon, 08 May 2017 19:25:01 GMT):
either should be fine

torresjeff (Mon, 08 May 2017 19:25:27 GMT):
ok

torresjeff (Mon, 08 May 2017 19:27:00 GMT):
@sstone1 it's not clear to me what exactly is the wallet doing in this case, I still have to specify the user id and secret to connect to the network

torresjeff (Mon, 08 May 2017 19:27:24 GMT):
isn't the purpose of the wallet to be able to connect with the credentials that are already stored there?

sstone1 (Mon, 08 May 2017 19:29:09 GMT):
in this case i'm letting the app enroll first time round

sstone1 (Mon, 08 May 2017 19:29:18 GMT):
when it enrolls it asks the wallet to persist the certificate

sstone1 (Mon, 08 May 2017 19:29:29 GMT):
any subsequent attempts will use the certificate stored in the wallet

sstone1 (Mon, 08 May 2017 19:29:42 GMT):
if you prepopulate the wallet with the certificate, it will never use the enrollment secret

torresjeff (Mon, 08 May 2017 19:29:47 GMT):
ohhhh

torresjeff (Mon, 08 May 2017 19:29:49 GMT):
I see

sstone1 (Mon, 08 May 2017 19:29:55 GMT):
we have some work to do to make the enrolment secret, currently its required

sstone1 (Mon, 08 May 2017 19:29:55 GMT):
we have some work to do to make the enrolment secret optional, currently its required

sstone1 (Mon, 08 May 2017 19:30:05 GMT):
you can set the secret to be "notrequired" though and it'll work ;)

sstone1 (Mon, 08 May 2017 19:30:14 GMT):
(as long as you already have the certificate!!!)

torresjeff (Mon, 08 May 2017 19:30:24 GMT):
thanks for clearing that up

sstone1 (Mon, 08 May 2017 19:30:27 GMT):
np

torresjeff (Mon, 08 May 2017 19:31:54 GMT):
so if I have multiple certificates in my wallet, it will look for the one with the userId that I specified as an argument in `connect()`?

sstone1 (Mon, 08 May 2017 19:32:13 GMT):
correct

sstone1 (Mon, 08 May 2017 19:33:24 GMT):

yep

sstone1 (Mon, 08 May 2017 19:47:55 GMT):
also some pending work to clean that up

sstone1 (Mon, 08 May 2017 19:48:06 GMT):
i don't like anything about that property

torresjeff (Mon, 08 May 2017 19:48:12 GMT):
lol

sstone1 (Mon, 08 May 2017 19:49:26 GMT):
1) it requires a full path which makes portability between different machines way too difficult 2) "keyValStore" means nothing to anybody... "keyStore" might be better, but "wallet" seems to be the popular term in the Blockchain world

torresjeff (Mon, 08 May 2017 19:49:57 GMT):
yup, agree with you there

torresjeff (Mon, 08 May 2017 19:50:07 GMT):
it's a pain to change the path when deploying to bluemix

sstone1 (Mon, 08 May 2017 19:50:16 GMT):
:+1:

sstone1 (Mon, 08 May 2017 19:50:20 GMT):
i'd like to make it optional

sstone1 (Mon, 08 May 2017 19:50:28 GMT):
and it just uses the name of the connection profile as the "default" wallet

sstone1 (Mon, 08 May 2017 19:50:42 GMT):
which would automatically provide isolation between different connection profiles

sstone1 (Mon, 08 May 2017 19:51:06 GMT):
and i think that would suit most of our users

torresjeff (Mon, 08 May 2017 19:51:20 GMT):
yes i think so

torresjeff (Mon, 08 May 2017 19:51:26 GMT):
regarding the object storage

torresjeff (Mon, 08 May 2017 19:51:36 GMT):
if i copy my certificates that i have on my local machine

torresjeff (Mon, 08 May 2017 19:51:44 GMT):
they would also work on bluemix right?

sstone1 (Mon, 08 May 2017 19:51:51 GMT):
yeah they should do

torresjeff (Mon, 08 May 2017 19:55:12 GMT):
is there any way to see the contents of the file in object storage?

torresjeff (Mon, 08 May 2017 19:55:20 GMT):
i'd like to know if it was copied correctly

torresjeff (Mon, 08 May 2017 19:55:42 GMT):
but apparently you can't open it

sstone1 (Mon, 08 May 2017 19:59:53 GMT):
you can download it

torresjeff (Mon, 08 May 2017 20:00:39 GMT):
oops

torresjeff (Mon, 08 May 2017 20:00:57 GMT):
have you also considered the name you use to store the certificates?

torresjeff (Mon, 08 May 2017 20:01:05 GMT):
eg: `admin` instead of `member.admin`

torresjeff (Mon, 08 May 2017 20:01:14 GMT):
changing the name*

sstone1 (Mon, 08 May 2017 20:01:30 GMT):
the wallet APIs strip off the prefix `member.`

torresjeff (Mon, 08 May 2017 20:01:54 GMT):
so if I upload my file with the name `member.admin` it would work?

sstone1 (Mon, 08 May 2017 20:02:01 GMT):
no, needs to be `admin`

davidkel (Mon, 08 May 2017 20:58:26 GMT):
@vinitesh that is a bit odd that it installed the chaincode but then failed to instantiate it (at least that is what it sounds like) can you see any chaincode instances running with a name org.acme.biznet ? Also I wonder if there were any errors in the peer logs related to instantiation ?

abcoathup (Mon, 08 May 2017 23:13:59 GMT):

In a transaction I want to assign available assets to a participant (both creating a new asset and using available assets), what is the recommended way to advise the client application what specific asset has been assigned to the participant?

dselman (Tue, 09 May 2017 05:27:52 GMT):
Sounds like a good use case for emitting an event: https://github.com/hyperledger/composer/issues/66

dselman (Tue, 09 May 2017 05:28:24 GMT):
@14gracel and @sstone1 are actively working on this at the moment.

abcoathup (Tue, 09 May 2017 05:37:56 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=SaEGnjM2ybtwvX9R4) @dselman Until there are events, I might just create a log of issued assets and get the client to pass in an ID to use for the log, so then the client can look up the assigned asset. A bit clunky, but feels better than having the client look for an available asset to pass to the transaction

abcoathup (Tue, 09 May 2017 05:39:26 GMT):
What is the suggested ID to use for assets/participants? I am using GUIDs. (As an aside, anyone got a good GUID function for use in a transaction processor function? I am using var guid; guid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8); return v.toString(16); }); from: http://stackoverflow.com/questions/105034/create-guid-uuid-in-javascript )

dselman (Tue, 09 May 2017 05:41:18 GMT):
GUID generation inside a TP function would be a bad idea -- each peer would create a different GUID, which will result in consensus failure. The GUID should be created/assigned by the client and passed in on the transaction.

dselman (Tue, 09 May 2017 05:42:04 GMT):
On the client (if in Node.js) you can use the `uuid` module.

dselman (Tue, 09 May 2017 05:43:08 GMT):
Remember there are N copies of your code executing and they all need to have the same side-effects on the ledger.

abcoathup (Tue, 09 May 2017 05:46:18 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=7jJTiNDuYtLMizdTW) @dselman Oops, centralised thinking there. Was thinking to push as much logic into TP function. Should I calculate ID from asset registry instead (sequential integer)? Otherwise need client work out if they need to use an existing asset or create a new asset if none available

dselman (Tue, 09 May 2017 05:49:33 GMT):
sequential integer would work, but just be aware that the sequence number generation is a global lock. Blockchain basically uses optimistic concurrency, and will rollback transactions when there is an optimistic concurrency failure.

dselman (Tue, 09 May 2017 05:49:47 GMT):
(aka consensus failure)

abcoathup (Tue, 09 May 2017 05:58:24 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=e7BWb7oFoymZ3N93Z) @dselman Thanks, you have sold me on the client passing in a GUID to use if I need to create an asset.

When should I use a concept?

abcoathup (Tue, 09 May 2017 05:58:48 GMT):
When should I use a concept rather than an asset?

dselman (Tue, 09 May 2017 06:31:59 GMT):
assets have an id and can be stored/managed in a registry. Concepts do not -- they are typically complex data structures that are contained by an asset, participant or transaction. E.g. an Address would be a Concept. A Customer would be an asset.

abcoathup (Tue, 09 May 2017 07:48:57 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=WmALQYHf7Yurj2ktg) @dselman I did the following, though assume there is a quicker way to update to latest version: '$ docker ps -aq | xargs docker rm -f $ docker images -aq | xargs docker rmi -f $ npm install -g composer-cli $ git clone https://github.com/hyperledger/composer-sample-applications-hlfv1.git $ cd composer-sample-applications-hlfv1/packages/getting-started $ npm install $ docker run -d -p 8080:8080 fabriccomposer/composer-playground '

abcoathup (Tue, 09 May 2017 07:51:22 GMT):
How can you tell what version of Playground you have running? It has connection profiles so must be 7.1.

dselman (Tue, 09 May 2017 07:54:00 GMT):
We used to display the version number in the UI... I believe @EdMoffatt will be helping us bring it back!

vinitesh (Tue, 09 May 2017 08:56:12 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=pdaQT6CFw7o4Typbe) @davidkel I think its unable to install the chaincodde as i cannot see any instances in the Blockcahin service console. Also org.acme.biznet is not a part of my network namespace. In the blockchain service there is only one chaincode installed which i deployed a week earlier using composer-cli. During the connect process i can see the following in the Peer logs. 2017-05-09 08:43:57.724 UTC [msp] Validate -> INFO 1547d3f[0m MSP PeerOrg1 validating identity [31m2017-05-09 08:43:57.732 UTC [lccc] Invoke -> ERRO 1547d40[0m ChaincodeId: org.acme.biznet does not exist on channel: ServicePartnerChannel(err:chaincode not found org.acme.biznet)

davidkel (Tue, 09 May 2017 08:59:45 GMT):
I'll let @sstone1 or @dselman correct me here as I am not familiar enough with playground yet but it looks like as part of the switching to a different connection profile playground sets up a blank business network called org.acme.biznet and attempts to deploy that to the fabric. If that fails for any reason then it fails to switch to that connection profile (I could be wrong about this though).

sstone1 (Tue, 09 May 2017 09:30:54 GMT):
:+1: we only let you use the org.acme.biznet business network with playground

sstone1 (Tue, 09 May 2017 09:31:36 GMT):
that clearly needs to change though ;)

dselman (Tue, 09 May 2017 09:46:53 GMT):
It does. That is confusing. Do we have a story for that?

sstone1 (Tue, 09 May 2017 09:51:07 GMT):
I had a chat yesterday with @EdMoffatt who said he would raise one

davidkel (Tue, 09 May 2017 10:37:55 GMT):
@vinitesh Unfortunately that part of the log doesn't give any indication of what happened once the business network was installed and it tried to instantiate. It would have been earlier in the logs when you first tried the unstable version of playground.

vinitesh (Tue, 09 May 2017 12:00:55 GMT):
@davidkel In bluemix usually i get the logs of last 10 mins only , so the logs for the time i first tried with unstable version won't be available. But what i understand from @sstone1 comment is playground will only allow us to deploy org.acme.biznet.0.7.2-20170508150422 network regardless of whatever network is loaded in my browser. So by the error you think that the org.acme.biznet.0.7.2-20170508150422 network was deployed when i first tried with the unstable version of playground but its not able able to instantiate and later installations are failing beacause that network already exits on blockchain.

vinitesh (Tue, 09 May 2017 12:02:05 GMT):
So is there any way by which i can uninstall the org.acme.biznet.0.7.2-20170508150422 network from bluemix blockchain service. In the channel trail i can see that undeploy command is not yet supported by connector

davidkel (Tue, 09 May 2017 12:06:16 GMT):
@vinitesh unfortunately there isn't any way to remove it (undeploy if implemented wouldn't solve the problem either because currently hyperledger fabric provides no capability to remove chaincode).I'm currently putting a fix in to try to ignore already exists messages so that the instantiate will be tried. It's not ideal. An alternative for now would be to get a newer version of playground than the 20170508150422 tagged version which is what you have.That will install a chaincode package at a different version so will allow the install to go ahead

vinitesh (Tue, 09 May 2017 12:15:14 GMT):
@davidkel shall i take 0.7.2-20170509102910 tag or pull the unstable again

davidkel (Tue, 09 May 2017 12:16:18 GMT):
@vinitesh as they are all just unstable releases and unstable tag just points to the very latest unstable version you could try unstable or one tagged with a slightly newer date I don't think it will make much difference

vinitesh (Tue, 09 May 2017 12:16:45 GMT):
@davidkel ok thanks

paul.sitoh (Tue, 09 May 2017 12:28:58 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=PK64yPzmhbRcXSzG8) @dselman that issue is here: https://github.com/hyperledger/composer/issues/902 (got round to raising it today)

guyho (Tue, 09 May 2017 16:34:55 GMT):
Wondering on work-around for an issue. I’ve created a couple assets, then modified the model with additional optional attributes, deployed successfully. Now the asset registry complains of missing required fields, but won’t let me see the registry to modify or delete the assets. Likely a novice user issue. :/

torresjeff (Tue, 09 May 2017 16:40:57 GMT):
@dselman should composer throw an error if I try to add another asset with the same id? i'm currently not getting any

torresjeff (Tue, 09 May 2017 16:41:30 GMT):
sorry I'm currently trying to add another participant, using an already existing id

torresjeff (Tue, 09 May 2017 16:41:36 GMT):
but not getting any errors

dselman (Tue, 09 May 2017 16:41:43 GMT):
it should throw an error

dselman (Tue, 09 May 2017 16:41:55 GMT):
make sure you are using a participant registry

dselman (Tue, 09 May 2017 16:42:06 GMT):
and that the type is the same

torresjeff (Tue, 09 May 2017 16:42:55 GMT):
everything seems ok

dselman (Tue, 09 May 2017 16:42:56 GMT):
@guyho if you've only added optional attributes then runtime should not be complaining

EdMoffatt (Tue, 09 May 2017 16:43:00 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=JmDFfTiLTy76QuTcR) @guyho You've hit one of the open issues I'm afraid! I've detailed out what we intend to do about it in the latest comment on it here: https://github.com/hyperledger/composer/issues/601 . What Composer *should* do is to warn you if you're making a change that might invalidate your existing assets, then deal better with displaying invalidated ones. Right now, as you spotted, it's too easy for new users to trip up

EdMoffatt (Tue, 09 May 2017 16:43:28 GMT):
Ah, as Dan says, that's only if tha attributes you added are non-optional - sorry, miss-read your original post!

guyho (Tue, 09 May 2017 16:44:13 GMT):
@dselman Yes, they're marked as "o" so, that's what surprised me.

EdMoffatt (Tue, 09 May 2017 16:44:41 GMT):
Ah, that "o" is not declaring something as optional, that's the trick here :) Let me just whip up a quick example...

dselman (Tue, 09 May 2017 16:46:24 GMT):
Examples here: https://hyperledger.github.io/composer/reference/cto_language.html

EdMoffatt (Tue, 09 May 2017 16:48:03 GMT):
asset SampleAsset identified by assetId { o String assetId o String requiredValue o String optionalValue optional } There, the only optional value is the optionalValue. The "o" at the beginning is part of the modelling language

EdMoffatt (Tue, 09 May 2017 16:48:13 GMT):
Dan's link for full details :)

EdMoffatt (Tue, 09 May 2017 16:48:51 GMT):
Are you able to share a screenshot of your participant registry with both participants expanded, @torresjeff ?

torresjeff (Tue, 09 May 2017 16:53:45 GMT):
@EdMoffatt currently not using the playground, but creating the participant through the composer-client api

guyho (Tue, 09 May 2017 16:54:06 GMT):
Gotcha. I do find the example "optional" element in the docs. Was trying to understand what is this modeling language so I know what "o" represents. At first I thought it was a circle bullet point. Anyway, I reverted to old model, deployed, removed assets, updated model so I can move forward. Cheers!

torresjeff (Tue, 09 May 2017 16:55:25 GMT):
if for example i have the following: ``` connect(). then(() => { return clientRegistry.add(resource); }) .then((result) => { console.log("Client added successfully"); return res.json({"result": "success"}); }) .then(() => { return disconnect(); }) .catch(function (error) { console.error("Error adding client", error); return res.json({"error": error.message}); throw error; }); ```

torresjeff (Tue, 09 May 2017 16:55:35 GMT):
and i added a participant with an already existing id

dselman (Tue, 09 May 2017 16:55:38 GMT):
`o` is a `has a` containment

torresjeff (Tue, 09 May 2017 16:55:51 GMT):
then i would enter the `catch()` handler right?

dselman (Tue, 09 May 2017 16:56:20 GMT):
what is clientRegistry

dselman (Tue, 09 May 2017 16:56:21 GMT):
?

dselman (Tue, 09 May 2017 16:56:41 GMT):
after you connect you should call getParticipantRegistry(...)

dselman (Tue, 09 May 2017 16:57:04 GMT):
hang on... is that in a TP function?

torresjeff (Tue, 09 May 2017 16:57:09 GMT):
nope

dselman (Tue, 09 May 2017 16:57:10 GMT):
or client code?

torresjeff (Tue, 09 May 2017 16:57:11 GMT):
server side

torresjeff (Tue, 09 May 2017 16:57:13 GMT):
nodejs

torresjeff (Tue, 09 May 2017 16:57:23 GMT):
client yup

torresjeff (Tue, 09 May 2017 16:57:33 GMT):
i get all my registries when i start up my app

torresjeff (Tue, 09 May 2017 16:58:26 GMT):
I assigned `businessNetworkConnection.getParticipantRegistry('org.bancoomeva.acuerdo.Client')` to `clientRegistry`

dselman (Tue, 09 May 2017 16:58:27 GMT):
are you sure it is not a promise/async issue

dselman (Tue, 09 May 2017 16:58:31 GMT):
?

torresjeff (Tue, 09 May 2017 16:58:31 GMT):
when handling the promise

torresjeff (Tue, 09 May 2017 16:59:01 GMT):
would you suggest getting the participant registry every time i have to use it?

torresjeff (Tue, 09 May 2017 16:59:04 GMT):
like get a new one?

dselman (Tue, 09 May 2017 16:59:50 GMT):
you could get it once, but you need to ensure that the code that uses it doesn't run concurrently with the code that gets it... seen that bug several times

torresjeff (Tue, 09 May 2017 17:00:26 GMT):
my app only starts listening once i have gotten all my registries

dselman (Tue, 09 May 2017 17:00:59 GMT):
can you DM me the file in question?

torresjeff (Tue, 09 May 2017 17:01:07 GMT):

Anything that you'd like to see discussed @torresjeff ?

torresjeff (Tue, 09 May 2017 20:53:19 GMT):
@sstone1 that seems about right, really looking forward to the events progress ;)

sstone1 (Tue, 09 May 2017 20:54:52 GMT):
I'll give you a little preview; Liam has events going from the Blockchain (HLFv1) all the way to client applications using the `composer-client` Node.js API :ok_hand:

sstone1 (Tue, 09 May 2017 20:55:13 GMT):
Very exciting, we know lots of people are after it, and it opens up a lot of exciting integration possibilities

torresjeff (Tue, 09 May 2017 20:55:31 GMT):
:woo:

torresjeff (Tue, 09 May 2017 20:55:56 GMT):
is support for fabric v0.6 being considered?

sstone1 (Tue, 09 May 2017 20:56:20 GMT):
gonna chat about it tomorrow... hopefully won't take too much to backport the changes

torresjeff (Tue, 09 May 2017 20:56:33 GMT):
excellent

torresjeff (Tue, 09 May 2017 20:57:11 GMT):
@sstone1 will there be a video like this: https://www.youtube.com/watch?v=fdFUsrsv5iw

torresjeff (Tue, 09 May 2017 20:57:16 GMT):
for HLFv1?

torresjeff (Tue, 09 May 2017 20:58:14 GMT):
is some additional setup required for v1?

torresjeff (Tue, 09 May 2017 20:58:31 GMT):
haven't really tried v1 so wouldn't know if it's very similar/different

sstone1 (Tue, 09 May 2017 20:58:37 GMT):
Yes, I am keen to update that video. It needs an update to cover: Hyperledger Fabric v1.0 Rebrand from Fabric Composer to Hyperledger Composer Connection profile and identity support in the Playground, and removal of the old UI

torresjeff (Tue, 09 May 2017 20:58:53 GMT):
great

torresjeff (Tue, 09 May 2017 20:59:00 GMT):
looking forward to that as well

sstone1 (Tue, 09 May 2017 20:59:05 GMT):
v1 is a lot more powerful, but more work to configure

sstone1 (Tue, 09 May 2017 20:59:12 GMT):
we're trying to make it easier for first time users

sstone1 (Tue, 09 May 2017 20:59:27 GMT):
we have a v1 version of our getting started guide which sets up a simple v1 network

torresjeff (Tue, 09 May 2017 20:59:59 GMT):
i still haven't been able to get access to the limited beta on bluemix :'(

sstone1 (Tue, 09 May 2017 21:00:20 GMT):

Fantastic, thanks for the feedback @GoodFaith !

sstone1 (Tue, 09 May 2017 21:07:13 GMT):
@Sandeep currently this is not well documented

FYI, you don't need an access token unless you enable the security options

sstone1 (Tue, 09 May 2017 21:08:21 GMT):
even though the LoopBack UI shows it at the top

GoodFaith (Tue, 09 May 2017 21:14:30 GMT):
Sweet. Looking forward to it.

torresjeff (Tue, 09 May 2017 21:22:29 GMT):
@sstone1 I have a question, it's more about "good practices", would Blockchain completely replace databases?

torresjeff (Tue, 09 May 2017 21:22:48 GMT):
ie. in a bank, would you have all your clients in the ledger?

torresjeff (Tue, 09 May 2017 21:23:12 GMT):
and all their banking accounts, etc etc

sstone1 (Tue, 09 May 2017 21:29:01 GMT):
It really depends on the business network and the data: 1. Does the data actually need to be stored in the Blockchain and shared between participants? 2. Can the data be stored in the Blockchain and shared between participants? Do data protection rules prohibit it?

sstone1 (Tue, 09 May 2017 21:30:25 GMT):
You might also have significant amounts of existing systems and databases that you want to integrate with the Blockchain, it won't replace those overnight

torresjeff (Tue, 09 May 2017 21:30:45 GMT):
yup, that's where events come in

torresjeff (Tue, 09 May 2017 21:31:27 GMT):
so in the bank example, would it make sense to store all information about my clients in the ledger?

torresjeff (Tue, 09 May 2017 21:35:45 GMT):
or should i only store things i can share between participtans

torresjeff (Tue, 09 May 2017 21:36:28 GMT):
ie. store client data in a traditional database, and maybe store things like banking accounts in the blockchain?

torresjeff (Tue, 09 May 2017 21:36:58 GMT):
or just money transfers in the blockchain

Sandeep (Tue, 09 May 2017 21:37:37 GMT):
I am using sample applications hlfv1 project. I was able to create and deploy the bna file onto the hlfv1 network. Then I am started composer playground locally. To use the local hlfv1 network, what is the user id and secret I have to use on the composer playground?. I tried using user:admin and secret:adminpw for connecting to the hlfv1 profile and I am getting access denied error.

sanjay-saxena (Tue, 09 May 2017 21:38:14 GMT):
@sstone1 -- Is there a Getting Stated guide for building sample app using `Hyperledger Composer` based on `Hyperledger Fabric 1.0`?

sstone1 (Tue, 09 May 2017 21:40:30 GMT):
@torresjeff with human clients, you're probably storing PII/SPI somewhere which you have to be pretty careful about storing in a shared, immutable blockchain

sstone1 (Tue, 09 May 2017 21:41:10 GMT):
even if it's encrypted... one day it could be decrypted (due to increased CPU power, vulnerabilities, etc)

sstone1 (Tue, 09 May 2017 21:41:28 GMT):
so depends on how much you trust the other peers in the network ;)

sstone1 (Tue, 09 May 2017 21:42:02 GMT):
you might want to just store a minimal set of information like the account ID in the Blockchain, which is a link/reference to all of the data stored in a database elsewhere

@sanjay-saxena the quickstart runs against Fabric v1.0: https://hyperledger.github.io/composer/unstable/installing/quickstart.html

sstone1 (Tue, 09 May 2017 21:44:44 GMT):
All of the following docs (editing the business network, starting a REST API, generating an app) will work against HLF v1.0

sanjay-saxena (Tue, 09 May 2017 21:45:06 GMT):
@sstone1 -- Will that point to an `unstable` build of `Hyperledger Composer`?

sstone1 (Tue, 09 May 2017 21:45:09 GMT):
but you might need to supply the `-p hlfv1` argument to any commands to say that you want to use the HLF v1.0 connection profile

sstone1 (Tue, 09 May 2017 21:45:25 GMT):
no, it should use the latest good stable builds

sstone1 (Tue, 09 May 2017 21:45:38 GMT):

In a transaction I want to issue a type of asset to a participant e.g. a blue marble. Is best practice to get the transaction processing function to find an unassigned asset (e.g. free blue marble) or should the client find an unassigned asset and request it be assigned to the participant?

sstone1 (Wed, 10 May 2017 07:26:48 GMT):
@Sandeep your keyValStore property is set to `/home/sandy/.hfc-key-store` but you are running inside the Docker container. You need to use `/home/composer/.hfc-key-store` because `/home/sandy` does not exist inside the container.

Any ideas?

sstone1 (Wed, 10 May 2017 07:34:38 GMT):
@abcoathup you could do it in a transaction processor function, but you will need to make sure that the find function is deterministic and always comes up with the same answer. since we do not have complex query support yet, you will need to either use `getAll()` to get all the marbles, or a for loop with `get` to find the first free marble.

@vinitesh I have put a change in which will ignore this error and attempt to instantiate the already installed chaincode, but I don't think it would solve your problem. For some reason it appears that instantiation is failing for you. The only thing I can think of that could cause a timeout problem like that is the docker container being spun up to run the chaincode doesn't have enough memory and just dies. I am pretty sure that if the chaincode compilation fails or if the chaincode execution its a problem you should get an error message back. Only suggestion I have is to chase HSBN to try to find out what is happening to your chaincode containers and what memory allocation they have been given

when you use an unstable runtime (chaincode), you must use a matching unstable client

We have an application that was developed using traditional chaincode way. I am trying to migrate it to use composer. I cannot change the UI code. So, I am using composer rest server to modify the incoming calls from UI and convert it to use the composer rest API. Does that make sense?

not sure if this was asked and/or issue - but when using v0.7.1 local playground using two machines(x.x.x.133 - being playground app server, x.x.x.134 - being a web client connecting to 133), /tmp/keyValStore2 directory gets created but user(test_user3 in here)'s member.test_user3 key file can't be created nor able to connect/deploy to the fabric using composer running on 133. is this an issue?

stu2 (Thu, 11 May 2017 05:26:07 GMT):
I understand the hyperledger java SDK isn't fully baked yet. When it matures do you envision supporting java for implementing transaction logic within composer applications, or is composer likely to be node-only internally?

dselman (Thu, 11 May 2017 07:06:46 GMT):
@stu2 all I can say is that no one in the community has stepped up to add Java support, and it is not in the current plan.

dselman (Thu, 11 May 2017 13:27:08 GMT):
What composer and fabric version?

vinitesh (Thu, 11 May 2017 14:01:23 GMT):
@dselman Composer version is 0.7.1 and fabric x86_64-1.0.0-alpha

vinitesh (Thu, 11 May 2017 14:43:52 GMT):
@dselman just checked, for the unstable version of composer undeploy command is working

vinitesh (Thu, 11 May 2017 14:52:51 GMT):
As the undeploy command will only make the business etwork unavailable , any idea how can i cleanup my bluemix blockchain beta instance. Uninstalling existing networks and removing chaincode containers

davidkel (Thu, 11 May 2017 17:11:04 GMT):
@vinitesh Don't know if bluemix would have a solution for this sorry. I do know HLF doesn't have anything at the moment which is why all composer can do is make the business network unavailable.

dselman (Thu, 11 May 2017 17:13:03 GMT):
basically tear down the docker containers and restart

vinitesh (Thu, 11 May 2017 17:24:18 GMT):
@dselman ya if running in local i can kill the docker containers and rebuild but bluemix blockchain beta doesn't have this option

mohamoud.egal (Thu, 11 May 2017 17:29:12 GMT):
How can I start with a blank network on the Web playground?

@zArchitectBill Can you access this chan now?

zArchitectBill (Thu, 11 May 2017 18:03:23 GMT):
there we go!

zArchitectBill (Thu, 11 May 2017 18:03:50 GMT):
so here's what I just asked in the General channel: I know this is a really, really basic question, so excuse me for asking it: When I use the composer to create an "empty business network", I add a model file. When I try to change the namespace, it gives me an error `Error: The namespace cannot be changed and must be set to org.acme.model`. How can I change the namespace?? I can't edit the .bna file, as it's some sort of unique internal format that my text editor doesn't seem to understand

zArchitectBill (Thu, 11 May 2017 18:04:00 GMT):
related to Mohamoud's question

sstone1 (Thu, 11 May 2017 18:48:01 GMT):
@mohamoud.egal you can click Import, and select "Empty Business Network" from the list

sstone1 (Thu, 11 May 2017 18:49:11 GMT):
@zArchitectBill erm, I'm not sure I have a good answer

zArchitectBill (Thu, 11 May 2017 18:52:47 GMT):
So what I did was create an empty network and then I add a model file. But that added model file will not allow me to change the org

zArchitectBill (Thu, 11 May 2017 18:53:09 GMT):
it APPEARS that I might be able to get around this by bringing in an external .cto file

sstone1 (Thu, 11 May 2017 18:54:05 GMT):

I'm in the process of trying to import a .cto file but I have problems that are circumstances beyond your control - my text editor is giving me fits!

zArchitectBill (Thu, 11 May 2017 20:14:39 GMT):
So I just tried to add my own .cto file off my laptop. It acted like it was going to add it, but the file never shows up in the composer

zArchitectBill (Thu, 11 May 2017 20:25:07 GMT):
It detected the fact that there was a valid asset defined in the .cto file, so it appears to be of the proper format. But the add does nothing - the file doesn't show up in the Composer

dselman (Thu, 11 May 2017 20:52:54 GMT):
can you paste the file here? Or DM it to me?

stu2 (Thu, 11 May 2017 21:51:54 GMT):
In https://hyperledger.github.io/composer/reference/MeetTheModules.html it says to reference other APIs, for now plz contact the devs, only apis in composer-client and composer-admin are supported. If I had chaincode which needed to call out to an AWS service using the AWS Node SDK for instance, is this one of the scenarios where we should contact the dev team? Is the plan to allow chaincode to do more sophisticated operations including using libraries and invoking external services? I'm new to node.js btw, so apologies if this is an obvious question.

sstone1 (Thu, 11 May 2017 21:54:26 GMT):
@stu2 chaincode (or transaction processor functions in Composer terms) are executed in a JavaScript virtual machine written in Go, not Node.js. It is currently not possible to import Node.js modules from a transaction processor function or call out to an external service.

sstone1 (Thu, 11 May 2017 21:55:00 GMT):
We are very interested in adding Node.js chaincode support to Fabric, this is work we are planning on starting.

stu2 (Thu, 11 May 2017 21:58:32 GMT):
Using composer, is it possible to write chaincode logic in another language which does custom operations like this? If it were to be written in Go for instance. I'm guessing not, it sounds like composer logic executes currently in a custom sandbox. Is this type of usage pattern (in any language) something the team envisions tackling in the near term or long term (ballpark is fine).

sstone1 (Thu, 11 May 2017 21:59:10 GMT):
No, currently you can only develop JavaScript transaction processor functions.

sstone1 (Thu, 11 May 2017 21:59:26 GMT):
Once we have Node.js support in Fabric, we can exploit it and allow users to take advantage of npm modules.

sstone1 (Thu, 11 May 2017 21:59:51 GMT):
That's a while off (>3 months minimum) I would say though.

stu2 (Thu, 11 May 2017 22:00:20 GMT):
Thanks for the info

sstone1 (Thu, 11 May 2017 22:00:24 GMT):
np

sstone1 (Thu, 11 May 2017 22:01:02 GMT):
Can I ask about the scenario - are you able to provide more information on what the AWS service is being used for?

stu2 (Thu, 11 May 2017 22:05:07 GMT):
Absolutely. I'm putting together a writeup of the scenario today, I'd love to share it with the group. Nutshell, in clinical phase 1 trials there's a global challenge to identify definitively volunteers and ensure that they're not participating concurrently in multiple trials. For safety of the subject and for trial integrity. For a variety of reasons I believe this is a clear and fairly simple use case for a private blockchain leveraging some basic biometrics. I'd like to prototype it using AWS Rekognition, accepting a simple photo taken at the clinical site during registration, and doing a facial recog search. ...actually before I type in my whole writeup here why don't I stop, complete it and send it along to anyone interested tonight :-). Hyperledger seems like a strong fit, I'm not quite sure if Composer is yet at the point where it's ready yet.

sstone1 (Thu, 11 May 2017 22:15:42 GMT):
Cool! You might like to mention it in #requirements-wg - they are very interested in collecting information on use cases

stu2 (Thu, 11 May 2017 22:17:34 GMT):
Thanks for the tip! will do, very happy to share, and excited that your team is so outward-facing and transparent. The whole Hyperledger project is extremely exciting

sstone1 (Thu, 11 May 2017 22:21:17 GMT):
Great to have you onboard, and we're very happy to be part of Hyperledger :)

Hi -- I am trying to generate Angular2 app using `yo hyperledger-composer:angular` command. I have already started `Hyperledger Fabric 1.0` and `digitalproperty-network` is already deployed to the instance. However, the command to generate Angular2 app gets stuck. When I abort(Ctrl-C) the command, I see the following error message: ``` ^CError: Deployed chain-code (0.7.1) is incompatible with client (0.7.2-20170510135245) at queryChainCode.then (/usr/local/lib/node_modules/generator-hyperledger-composer/node_modules/composer-connector-hlfv1/lib/hlfconnection.js:498:27) ``` AFAIK, I have `Hyperledger Composer 0.7.1` installed on my machine. So, I am not sure where the 0.7.2 build from yesterday is being picked up.

might have been command line, my partner did that so I'm not sure, but it deploys to the web UI just fine

dselman (Fri, 12 May 2017 04:51:27 GMT):
I suggest you create the BNA yourself using `composer archive create -t dir -n .` and you check that you are using the right connection profile when you do the `composer network update` (using the -p argument). You will need the connection profile document from your colleague that deployed the network for that to work on v0.6.

I am trying to create a connection profile on fabric-composer. The Fabric composer running locally with docker image fabriccomposer/composer-playground And I have local fabric V1 (No Vagrant) network running on MacOS. How do I create a connection profile in composer. When I try to create connection profile it fails with Error: PEM encoded certificate is required. Apart from Peer / Orderer , I am not sure what are the values for keystore ,etc to be set in case of local n/w ? Can we also configure the composer connection profile with Bluemix Blockchain V1 service ? Please share your inputs.

dselman (Fri, 12 May 2017 05:11:52 GMT):
Simplest way on the Mac is to run @sstone1 magic script - which makes it a 1 liner... See https://chat.hyperledger.org/channel/composer?msg=SL4CL5rrYCjGPEShM

dselman (Fri, 12 May 2017 05:12:49 GMT):
This will start Playground and HLF v1 and define a connection profile so that Playground can connect to HLF v1.

@dselman -- I had tried uninstalling and installing `composer-cli`. However, I still the same issue with `yo hyperledger-composer:angular` command. Note that I am able to submit transactions and such. The problem seems to be with difference in the Composer versions that are in play. I have filed this ticket -- https://github.com/hyperledger/composer/issues/959.

berserkr (Fri, 12 May 2017 06:01:48 GMT):
when I create a PointType, I essentially need to get the Issuer of the PointType, think of this as a currency/token

berserkr (Fri, 12 May 2017 06:03:41 GMT):
my cto file has: `asset PointType identified by id { o String id o String name --> Issuer issuer }`

berserkr (Fri, 12 May 2017 06:04:18 GMT):
So basically, I am trying to get the Issuer reference, but when I get it, and try to create the PointType with said reference, I am getting an exception

ignore the '' in the registry

sstone1 (Fri, 12 May 2017 06:35:51 GMT):
you must use the factory to create new relationships (they are special objects)

berserkr (Fri, 12 May 2017 06:36:08 GMT):
the issuer is the relationship I am unable to create

berserkr (Fri, 12 May 2017 06:36:13 GMT):
I have the issuerId

sstone1 (Fri, 12 May 2017 06:36:13 GMT):

want to paste in the new code?

pointType.issuer = factory.newRelationship('org.acme.model.PointType', 'Issuer', issuerId);

berserkr (Fri, 12 May 2017 06:43:02 GMT):
at this point I pased the issuerId from the js at the top

berserkr (Fri, 12 May 2017 06:43:07 GMT):
no longer an object

sstone1 (Fri, 12 May 2017 06:43:26 GMT):
as per my example above, you don't need the PointType in the first argument

sstone1 (Fri, 12 May 2017 06:43:39 GMT):

davidkel (Fri, 12 May 2017 08:04:17 GMT):
@indira.kalagara I assume you are using docker images created from the fabric source rather than pulling down the alpha images from docker ?

indira.kalagara (Fri, 12 May 2017 08:04:38 GMT):
yeah...thats right

indira.kalagara (Fri, 12 May 2017 08:04:46 GMT):
not alphas images

davidkel (Fri, 12 May 2017 08:06:04 GMT):
@indira.kalagara Sorry composer doesn't work with anything beyond the alpha images due to breaking api changes made since the alpha release. When alpha2 is released by fabric then we will move to supporting that drop

indira.kalagara (Fri, 12 May 2017 08:07:01 GMT):
oh..Okie...we want to port it finally to Blockchain on blumeix...and hence I have pulled the latest images

indira.kalagara (Fri, 12 May 2017 08:07:37 GMT):
does composer-cli works with latest images ?

davidkel (Fri, 12 May 2017 08:08:09 GMT):
@indira.kalagara sorry no. non of composer will work with the latest images

davidkel (Fri, 12 May 2017 08:33:18 GMT):
@indira.kalagara have you had a problem trying composer through our getting started for example ? we've had no problems with using MacOS

sstone1 (Fri, 12 May 2017 08:33:21 GMT):
@SahilKapoor have you seen this tutorial? https://hyperledger.github.io/composer/tutorials/defining-a-business-network.html It walks through the car auction network, which is a much better sample then the marbles sample.

sstone1 (Fri, 12 May 2017 08:33:35 GMT):
Alternatively, you can use "Import" in the playground to import the marbles sample.

SahilKapoor (Fri, 12 May 2017 08:34:59 GMT):
@sstone1 I dint see this page last time I checked the documentation .. Thanks...

Hello, If I try and specify a path to a keystore directory other than .hfc-key-store I hit the following problem, reported as follows ``` Error: Private key missing from key store . In the default .hf-key-store pub file is getting created where as the the priv file is created in the new keystore. I saw a issue around this in jira https://jira.hyperledger.org/browse/FAB-2940 but not sure whether its link to composer or not

davidkel (Fri, 12 May 2017 09:21:39 GMT):
@vinitesh due to issues with the alpha version of the fabric sdk node, you can't specify any other keystore directory than .hfc-key-store in your home directory

davidkel (Fri, 12 May 2017 09:22:30 GMT):
@indira.kalagara I suggest trying out our getting started for hlf1 which uses the alpha images. We have had no problems running this on MacOS

sstone1 (Fri, 12 May 2017 09:25:23 GMT):
@here we've released Hyperledger Composer v0.7.2, read all about it on GitHub: https://github.com/hyperledger/composer/releases/tag/v0.7.2 🎉

vinitesh (Fri, 12 May 2017 09:26:21 GMT):
@davidkel any workaround for this as i need to deploy my node sdk client to bluemix and there i need to specify a different path to keystore

davidkel (Fri, 12 May 2017 10:16:53 GMT):
@vinitesh bluemix apps still have a concept of a home directory so it should be possible to specify the directory .hfc-key-store in that home directory

davidkel (Fri, 12 May 2017 10:18:37 GMT):
@vinitesh you can also specify the connection profile in an environment variable COMPOSER_CONFIG.

vinitesh (Fri, 12 May 2017 10:19:47 GMT):
connectionProfile is ok

davidkel (Fri, 12 May 2017 10:20:22 GMT):
There is also the wallet api mentioned previously in this chat [ ](https://chat.hyperledger.org/channel/composer?msg=dj4NqtJ2W2emAz8QX) and Simon's example https://github.com/sstone1/sample-bluemix-composer-app

vinitesh (Fri, 12 May 2017 10:20:53 GMT):
but when i give the give keystore value as /home/vcap/.hfc-key-store its still gives the same problem

vinitesh (Fri, 12 May 2017 10:23:39 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=duTJqm98sGYjQJM8T) @davidkel this is interesting , i will give it a try

davidkel (Fri, 12 May 2017 10:24:13 GMT):
@vinitesh thinking about it, you don't want to be using the file system for storing this information anyway. If your app crashes or goes down the file system will be wiped

vinitesh (Fri, 12 May 2017 10:26:23 GMT):
@davidkel ya that make sense but just for demo purpose , is /home/vcap/.hfc-ket-store correct path for keystore on bluemix app

vinitesh (Fri, 12 May 2017 10:26:23 GMT):
@davidkel ya that make sense, but just for demo purpose , is /home/vcap/.hfc-ket-store correct path for keystore on bluemix app

davidkel (Fri, 12 May 2017 10:29:09 GMT):
@vinitesh sorry I don't know. The fabric client uses the following code to determine the default ``` os = require('os') path.join(os.homedir(), '.hfc-key-store'); ``` so it will be whatever that call returns will be the one you need to use

vinitesh (Fri, 12 May 2017 10:30:47 GMT):

I ll try it over the weekend.

dselman (Fri, 12 May 2017 10:48:39 GMT):
No, you can stay on 0.7.1 if you wish... but upgrade is painless so I'd recommend moving up to 0.7.2

guyho (Fri, 12 May 2017 13:49:06 GMT):
Is process for updating composer playground to re-run docker pull, i.e., "docker pull hyperledger/fabric-baseimage:x86_64-0.1.0"?

jtonline (Fri, 12 May 2017 13:49:19 GMT):
@guyho there was an issue with some of the samples... https://github.com/hyperledger/composer/issues/964

jtonline (Fri, 12 May 2017 13:51:04 GMT):
...but that's 0.7.2 and should only be for three of the samples (the ones with no permissions.acl file)

FenglianXu (Fri, 12 May 2017 14:09:57 GMT):
@silliman You would need a separate READ operation

what is the right approach to updating composer playground, locally?

Jakeeyturner (Fri, 12 May 2017 15:14:20 GMT):
@jje The 'historian' hopes to be able to do this (once it's created). At the moment it's not possible to see the history of an asset after a transaction has interacted with it

vinitesh (Fri, 12 May 2017 15:32:17 GMT):
@davidkel @sstone1 @dselman Is there a plan to provide additional functionality for undeploy command in the future release like uninstalling the network and removing the chaincode containers?

sstone1 (Fri, 12 May 2017 15:32:37 GMT):
@vinitesh yes, when Fabric provides support for doing that

vinitesh (Fri, 12 May 2017 15:34:46 GMT):
@sstone1 any story around that?

davidkel (Fri, 12 May 2017 15:38:46 GMT):
@vinitesh The requirement is down to hyperledger fabric to provide the capability and then once they do we can exploit it. It should be something they are aware of and should know to provide but I have no idea when they might or where it might be tracked.

You can import/replace samples into Playground, edit them (they are saved in browser local storage) and then export them to an BNA file (archive).

zArchitectBill (Fri, 12 May 2017 17:33:14 GMT):
So I've been using a local copy of the Composer on Ubuntu 16.4, running in a Docker container. About an hour ago, my Composer UI changed - it no longer has a Connection icon in the upper right (the little globe), and now has a "Get local version" link. WHY?

zArchitectBill (Fri, 12 May 2017 17:34:08 GMT):
I deleted the composer Docker image and restarted and forced the Composer container to re-download. And it's still broken. And it's telling me my credentials are wrong. Things are totally hosed now. How can I reset it?

zArchitectBill (Fri, 12 May 2017 17:34:31 GMT):
I thought the local copy of the Composer would always have the Connection icon so I could connect to a remote fabric

zArchitectBill (Fri, 12 May 2017 17:34:40 GMT):
I had it working last night and this morning so it would connect to Bluemix

zArchitectBill (Fri, 12 May 2017 17:34:51 GMT):
but it just seemed to change itself

zArchitectBill (Fri, 12 May 2017 17:35:29 GMT):
I was connected to localhost:8080, so it wasn't (as far as I know) hitting the web version (which I know doesn't have connection feature)

zArchitectBill (Fri, 12 May 2017 17:36:54 GMT):
it sure would be nice to be able to delete an identity. All I can see is the ability to add one...

sanjay-saxena (Fri, 12 May 2017 17:51:29 GMT):
@dselman -- With 0.7.2, the generator issue is resolved. It would be good if the entire toolset is dependent on the same component versions to avoid this issue in the future. Or, if the backward compatibility of the chaincode across patches(the third digit in the version# -- major.minor.patch-build, 0.7.X) can be guaranteed.

dselman (Fri, 12 May 2017 17:53:59 GMT):
Glad to hear you're up and running. The entire toolset (well, everything under the `composer` repo) uses the same version number and advances in lock-step. So somehow you'd installed a mix of versions -- had you been playing with unstable releases? The unstable releases are published (and tagged as unstable) on every commit that passes our CI/CD pipeline, but you need to specific ask npm to install them using the `@unstable` tag.

sanjay-saxena (Fri, 12 May 2017 17:54:36 GMT):
Nope. I was just doing regular `npm install -g `.

dselman (Fri, 12 May 2017 17:55:23 GMT):
Very odd. Did you use the magic install script from @sstone1 ?

sanjay-saxena (Fri, 12 May 2017 17:56:10 GMT):
Nope. I am so new to `npm` that I did not know that one can be at the bleeding edge using `@unstable`.

dselman (Fri, 12 May 2017 17:56:47 GMT):
Ok, mystery how that got installed. Should not happen...

sanjay-saxena (Fri, 12 May 2017 17:57:16 GMT):

dselman (Fri, 12 May 2017 18:25:51 GMT):
did you check the ports in his connection profile?

dselman (Fri, 12 May 2017 18:26:34 GMT):
Most likely explanation is that connection profile is wrong.

jdockter (Fri, 12 May 2017 18:26:52 GMT):
ah okay let me look

davidkel (Fri, 12 May 2017 18:42:14 GMT):
I bet he is isn't specifying a profile so it is using defaultProfile so its trying to use a v0.6 against a running v1 system

jdockter (Fri, 12 May 2017 18:42:55 GMT):
ah crapper...yes that is it

jdockter (Fri, 12 May 2017 18:43:02 GMT):

@jdockter is that a technical term ? :-)

jorgedr (Sat, 13 May 2017 23:24:03 GMT):
Hey guys, I recently started to have issues deploying the .bna file for our business network. Sometimes a .bna file that has deployed before stop from working and I can no longer deploy it. The way we deploy our network is by undeploying the previous network and redeploying it again. Sometimes I can get a .bna file to deploy then the same file deployment fails. I made sure it is not that we are timing out (I increased the deployment timeout setting in the profile). Do you guys know what log files should I look into in order to find out why deployments are failing? I am using Fabric v0.6 in Bluemix. There are several log files that I can access from Bluemix, one being the peer log, the CA log and the actual chaincode logs.

dselman (Sun, 14 May 2017 08:01:30 GMT):
you should not run it with `sudo`. Did you run `npm install -g composer-cli` first, as indicated by the error?

SahilKapoor (Sun, 14 May 2017 08:01:43 GMT):
ya

[ ](https://chat.hyperledger.org/channel/composer?msg=rWE2b6TMTTNJqPCQc) @jorgedr if a deploy is failing, look in the peer logs. If an update is failing look in the chaincode logs.

SahilKapoor (Sun, 14 May 2017 08:04:00 GMT):
@dselman I installed composer using sudo

SahilKapoor (Sun, 14 May 2017 08:46:48 GMT):
one more question , The recommended minimum versions are: Docker: v1.12.3 Docker-compose: v1.10.0 npm: v4.6.0 node.js: v6.9.5

SahilKapoor (Sun, 14 May 2017 08:47:12 GMT):
But when we install node , npm version we get is 3.10

SahilKapoor (Sun, 14 May 2017 08:47:34 GMT):
so it necessary to update it to npm 4.6

SahilKapoor (Sun, 14 May 2017 08:47:54 GMT):
and what should ideally be composer -v

dselman (Sun, 14 May 2017 08:48:08 GMT):
yes, just an `npm update -g npm`

dselman (Sun, 14 May 2017 08:48:21 GMT):
but run the pre-req script

SahilKapoor (Sun, 14 May 2017 08:48:22 GMT):
ok

dselman (Sun, 14 May 2017 08:48:37 GMT):
we test that now as part of the system tests, in an empty VM

SahilKapoor (Sun, 14 May 2017 08:49:15 GMT):
Yes. Will keep you posted. Thanks for the help.

SahilKapoor (Sun, 14 May 2017 08:49:24 GMT):

if you start the Fabric using the getting-start-v1 repo (as described here https://hyperledger.github.io/composer/installing/quickstart.html) then the script will also create your connection profile

@ASMP when you say you started fabric using network_setup.sh does that mean you are using the e2e_cli command from the fabric repo and If so I assume you aren't using the 1.0.0-alpha images ? Composer can only interact with 1.0.0-alpha fabric

as per the documents

dselman (Sun, 14 May 2017 11:28:03 GMT):
then typed `npm install`

SahilKapoor (Sun, 14 May 2017 11:28:04 GMT):
yes

SahilKapoor (Sun, 14 May 2017 11:28:08 GMT):
yup

SahilKapoor (Sun, 14 May 2017 11:31:35 GMT):
I think issue is related to creating of a channel , as all peers ca ordering service are created

dselman (Sun, 14 May 2017 11:32:40 GMT):
strange that it can't find grpc though

dselman (Sun, 14 May 2017 11:32:57 GMT):
@davidkel any idea?

sstone1 (Sun, 14 May 2017 11:33:03 GMT):
it suggests that the native module build failed to work

dselman (Sun, 14 May 2017 11:33:26 GMT):
yes, but I would have thought that would have failed composer-cli as well?

sstone1 (Sun, 14 May 2017 11:33:27 GMT):
e.g. no g++/gcc/python etc

@SahilKapoor can you run `npm install grpc`

SahilKapoor (Sun, 14 May 2017 11:36:44 GMT):
Sure..

sstone1 (Sun, 14 May 2017 11:36:50 GMT):

Still the same error

SahilKapoor (Sun, 14 May 2017 11:40:03 GMT):
Is it because of 7.2 tag

SahilKapoor (Sun, 14 May 2017 11:40:23 GMT):

node-gyp requires python v2.x, and node-gyp builds native modules

SahilKapoor (Sun, 14 May 2017 11:51:38 GMT):
I thought python would be installed as a pre requisite

sstone1 (Sun, 14 May 2017 11:51:52 GMT):
it should have been installed by the prereqs script

sstone1 (Sun, 14 May 2017 11:52:35 GMT):
infact i'm surprised python is not installed by default on ubuntu

sstone1 (Sun, 14 May 2017 11:53:13 GMT):
`sudo apt-get install python` i guess!

sstone1 (Sun, 14 May 2017 11:53:29 GMT):
then make sure you can run `python -v` and it outputs `2.7.*`

sstone1 (Sun, 14 May 2017 11:53:39 GMT):
then `git clean -xdf` again and then run `npm install`

@tennenjl does that error happen immediately or after a period of time?

@sstone1 after a period of time

@stone1, we increased the deploy timeout value in the connection profile

Pasteis (Sun, 14 May 2017 18:07:05 GMT):
@sstone1 certain aspects of an asset model could be relevant for some audiences but not others (roles). Hence, I would like to have that fine grained control. Now, if not possible from model definition in composer. Do you know what part of loopback component that does the mapping from model fields to APIs?

sstone1 (Mon, 15 May 2017 06:15:44 GMT):
@tennenjl that probably means it's the event hub issue - the "Connection reset by peer" looks suspiciously like that

sstone1 (Mon, 15 May 2017 06:24:47 GMT):
@Pasteis just to check what you mean by relevant - do you mean that certain audiences/roles are not permitted to see certain properties, whilst others are? we have an unfinished piece of work for the ACL rules ( `permissions.acl` ) that allows you to secure assets at a per property level, allowing you to allow/deny access to particular fields (and that would flow through to the REST server). one problem with removing properties from the model is that if the property is required, nobody will be able to add/update instances of that model. if you want some users of the REST server to see the properties and some not, then the ACL rules is the way forwards.

jje (Mon, 15 May 2017 06:24:59 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=vQRFgYXfEz2pdfJNQ) @Jakeeyturner Do I understand this correctly that I can't read back the history of an asset? Let's assume my asset is a container, I cannot trace back the transactions associated with this container? If this is the case, how can I implement a traceability use case with composer?

sstone1 (Mon, 15 May 2017 06:25:38 GMT):
if you want to look into it from the loopback side of things, all Composer models use the `PersistedModel` base class which takes care of mapping from the model to REST APIs. i think that's all in the `loopback` module.

Doing a fresh follow-through of the Getting Started instructions... Got to a point where I run: composer archive create --sourceType dir --sourceName . Suggested output is: Description:Digital Property Network Name:digitalproperty-network Identifier:digitalproperty-network-0.0.22 What I actually see in console is: Description:Digital Property Network Name:digitalproperty-network Identifier:digitalproperty-network@0.0.8 Did the version number decrement with newer instructions?? I'd be ok to just dismiss it if I were seeing a higher version number that what's in the docs, but... (Also, the docs should probably not then tell you to do a command that depends on that Identifier without having something like in there to indicate you need to pay some sorta attention to the output before you run the next command. Anyone know what's goin' on here?

@tennenjl thats the event hub issue - the giveaway is the `events.js:160 throw er; // Unhandled 'error' event` at the end

tennenjl (Mon, 15 May 2017 14:30:38 GMT):
@sstone1 So, I have to ask, is there any sort of way to address the event hub issue (server side) or otherwise, or at this point do we need to move to v1? Thanks!

sstone1 (Mon, 15 May 2017 14:31:31 GMT):
no way at v0.6. if we disable the event hub, we can't tell if a call to the blockchain has passed, failed, is still running, or timed out

sstone1 (Mon, 15 May 2017 14:31:42 GMT):
which is why the event hub property is required

sstone1 (Mon, 15 May 2017 14:32:07 GMT):
the problem isn't fixed yet at v1.0

sstone1 (Mon, 15 May 2017 14:32:28 GMT):
and similar problems occur - we can't tell if/when the transaction has been committed to the blockchain without the event hub

davidkel (Mon, 15 May 2017 14:45:08 GMT):
@EdMoffatt your command would only work with a v0.6 fabric. Try ``` composer network update --archiveFile digitalproperty-network@0.0.8.bna -p hlfv1 --enrollId admin --enrollSecret adminpw ``` (note that it is likely you have already enrolled admin so) ``` composer network update -a digitalproperty-network@0.0.8.bna -p hlfv1 -i admin -s Q ```

@jtonline i'm considering doing ecdsa signature verification inside the chaincode. this would require at least a few crypto npm modules.

jtonline (Mon, 15 May 2017 15:52:02 GMT):
@chunhui that sounds like one of the things that has come up before. Rather than wait for some kind of built in API/support, you could perhaps give browserify a go. I imagine there are going to be some pitfalls but crypto-browserify does seem to have createVerify (rsa, ecdsa) implemented so it may be worth a try. If you do get something working, it would be fantastic to hear about it.

So i used "class :Factory" which is creating an instance but it is not lasting for long. I mean the transaction operation to add the details to existing asset is disappearing when i jump or click on other asset or transaction. Please Can any help on this?

tennenjl (Mon, 15 May 2017 19:04:51 GMT):
OK... We get our registry so the code looks similar to this getAssetRegistry(REGISTRY_ID); }) .then(function(myAssetReg) { // Push new asset into the main asset registry return myAssetReg.add(someAsset); }) .catch(function(error) { // We should log error once we know how to do that and then re-throw it throw error;

Pasteis (Mon, 15 May 2017 19:09:39 GMT):
@sstone1 re APIs: Yes, in some cases it could be a matter of who see what and what part of CRUD is available for whom. So controlling fields (resources) and operations on them. This is usual APIM use cases and I thought since you picked loopback for this one could leverage the fuller APIM capabilities

Pasteis (Mon, 15 May 2017 20:32:29 GMT):
The other point to controlling API is that this is your external interface and you may want to expose a certain style/dialect of REST, including different external field names that get mapped to other internal ones.

Basic Question: Is writing logic in JS in composer same as writing logic in chaincode?

davidkel (Tue, 16 May 2017 06:48:48 GMT):
@SahilKapoor it should work with hlfv1 alpha. You should follow the quick start for hlfv1 rather than hlf v0.6 then in the tutorial when you use the command line to deploy/interact with your local fabric you should specify the profile hlfv1 using the command line option `-p hlfv1` (hlfv1 profile is created for you when you follow the quick start) and the emrollment secret `adminpw`. When you start the rest server and generate the application make sure you specify `hlfv1` as the profile and `adminpw` as the enrollment secret

davidkel (Tue, 16 May 2017 06:54:09 GMT):
@ygnr The programming models between writing chaincode in go and composer transaction processors in javascript with composer are completely different

GururajL (Tue, 16 May 2017 07:13:00 GMT):
I have a couple of questions, 1. what is the endorsement policy used when composer deploys the chaincode? is there a way to specify? 2. what is the plan for supporting channels involving multiple organisations?

dselman (Tue, 16 May 2017 07:59:44 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=FP3BJyJfxj5NAieQj) @ygnr you are operating at a different level of abstraction, but the logic is executing inside the chaincode container and side-effects are stored in the world-state. So from Fabric's point of view, this is just "chaincode"...

uber.twin (Tue, 16 May 2017 11:25:35 GMT):
@dselman hi, as far as I understand, the user enrollment means obtaining certificates for an existing user, in the context of a client application, isn't it?

davidkel (Tue, 16 May 2017 11:28:23 GMT):
@GururajL Composer doesn't specify any endorsement policy so it will revert to whatever is the fabric default and currently there is no way to specify endorsement policy. Composer has no reliance on how a channel is configured in a fabric so should work on different channel configurations

uber.twin (Tue, 16 May 2017 11:32:07 GMT):
@dselman I see the "enrolling" is performed explicitly by the the create-channel.js administrative routine but not in a regular business scenario, like the landRegistry.js sample

uber.twin (Tue, 16 May 2017 11:33:32 GMT):
or maybe it is done transparently by the composer-cli runtime?

[ ](https://chat.hyperledger.org/channel/composer?msg=ihWrEFSTyx9frNKcp) @dselman @davidkel Can we put condition on value of a relationship in permission.acl rule?

sstone1 (Tue, 16 May 2017 11:52:52 GMT):
@vinitesh the ACL engine does not currently resolve relationships in a way that would allow you to do that

sstone1 (Tue, 16 May 2017 11:53:20 GMT):
it would be OK if you were just accessing `r.package.getIdentifier()` but the problem is because you are trying to access a relationship of a relationship

vinitesh (Tue, 16 May 2017 13:08:15 GMT):
@sstone1 ya r.package.getIdentifier()`works, but while defining our network model as relational we need to have a functionality to set permissions based on muti tier relationships otherwise for setting up permissions we cannot set our model as relational. Is there anything we can use as a workaround for this problem?

sstone1 (Tue, 16 May 2017 13:18:02 GMT):
afraid not, we need to add code to make this possible

sstone1 (Tue, 16 May 2017 13:18:14 GMT):
unless you duplicate the `--> Individual individual` relationship in the `CC` asset

karthikworks (Tue, 16 May 2017 13:49:40 GMT):
This maybe a very basic question but bit confused Is it possible to switch between identities from Angular like how it does on composer playground...?

sstone1 (Tue, 16 May 2017 14:04:21 GMT):
sure, can you raise a requirement in GitHub?

sstone1 (Tue, 16 May 2017 14:04:30 GMT):
@karthikworks no, it is not currently possible

vinitesh (Tue, 16 May 2017 14:06:50 GMT):
@sstone1 ya sure thanks

karthikworks (Tue, 16 May 2017 14:08:12 GMT):
@sstone1 how do we control the access of the users... say for example i have two users and have identity given to them... now i want to test the angular application with one of them (who does not have access to certain assets).. right now i am unable to see the access control happening... each time we run it runs as an admin..

sstone1 (Tue, 16 May 2017 14:11:37 GMT):
The identity used by the Angular application is controlled by the REST server that it uses to communicate with the deployed business network

sstone1 (Tue, 16 May 2017 14:12:08 GMT):
You will see in `package.json` (of the Angular application) a `composer-rest-server` command that specifies the admin user by default

sstone1 (Tue, 16 May 2017 14:12:17 GMT):
Well, the user the was used in the Angular generator

Yes, because participants are modelled and because ACL rules can use any attributes on the participant this is quite easy to do. E.g. you can restrict asset access by type of participant, or by using metadata on the participant instance (company name etc).

dselman (Tue, 16 May 2017 17:22:29 GMT):
The docs for ACLs include some examples of different types of conditions

dselman (Tue, 16 May 2017 17:25:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=mtqNFFw8XSGtuNyBh) @GrahamCharters is this a v0.6 server running locally? What is in your defaultProfile ?

dselman (Tue, 16 May 2017 17:27:17 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=NCBfHsNXawKFLYKwx) @aashishshrestah could you DM me your BNA file and test case please?

dselman (Tue, 16 May 2017 17:31:40 GMT):
@aashishshrestah I think it is because the elements in your array need to be concepts (created using factory.newConcept) not plain JS Objects.

dselman (Tue, 16 May 2017 17:32:24 GMT):
The factory decorates the JS Objects with meta-annotations.

dselman (Tue, 16 May 2017 17:32:24 GMT):
The factory decorates the JS Objects with metadata.

aashishshrestah (Tue, 16 May 2017 18:07:05 GMT):
Thanks @dselman

rmohta (Tue, 16 May 2017 18:31:11 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=pSiq7dn3jmYu6YeWi) @dselman Thanks. Would you say composer is ready for fabric v1.0?

dselman (Tue, 16 May 2017 18:55:32 GMT):
Yes, it works nicely with Alpha1 - we are working on support for Alpha2, which was released yesterday.

torresjeff (Tue, 16 May 2017 19:22:00 GMT):
@sstone1 is it possible to make ´composer-rest-server´ use a wallet (in bluemix)?

torresjeff (Tue, 16 May 2017 19:22:00 GMT):
@sstone1 is it possible to make `composer-rest-server` use a wallet (in bluemix)?

rjones (Tue, 16 May 2017 19:37:33 GMT):
Has left the channel.

sstone1 (Tue, 16 May 2017 19:38:32 GMT):
@torresjeff yes - I'll give the long answer just to explain - `composer-rest-server` is a prebuilt LoopBack application that we have added "boot scripts" to in order to configure the Composer integration.

sstone1 (Tue, 16 May 2017 19:39:01 GMT):
You can take a copy of `composer-rest-server` and edit the boot scripts to set a wallet implementation - it's not possible to do this via connection profiles etc at the moment.

sstone1 (Tue, 16 May 2017 19:40:15 GMT):
Alternatively - you can configure `composer-rest-server` with a LoopBack connector to use to persist the wallet, for example MongoDB

sstone1 (Tue, 16 May 2017 19:40:50 GMT):
That is slightly more difficult though as you need to install additional LoopBack connectors *and* configure the connector with the details of the database

sstone1 (Tue, 16 May 2017 19:41:09 GMT):
How are you running the REST server in Bluemix? Cloud Foundry application or Docker container?

torresjeff (Tue, 16 May 2017 19:41:30 GMT):
cf app

torresjeff (Tue, 16 May 2017 19:42:25 GMT):
setup a script in my package.json like so: `"start": "composer-rest-server -p bluemix1 -n biznet -i admin -s 032de32a06 -N always && node app.js"``

torresjeff (Tue, 16 May 2017 19:42:58 GMT):
but it's looking for the conncetion profile in the file system

sstone1 (Tue, 16 May 2017 19:43:13 GMT):
right, you can fix that with env var

sstone1 (Tue, 16 May 2017 19:44:10 GMT):
``` export COMPOSER_CONFIG=' { "connectionProfiles": { "hlfabric": { "name": "hlfabric", "description": "Hyperledger Fabric v1.0", "type": "hlfv1", "keyValStore": "/home/composer/.hfc-key-store", "deployWaitTime": 300, "invokeWaitTime": 30, "orderers": [ { "url": "grpc://orderer0:7050" } ], "channel": "mychannel", "mspID": "Org1MSP", "ca": "http://ca0:7054", "peers": [ { "requestURL": "grpc://peer0:7051", "eventURL": "grpc://peer0:7053" }, { "requestURL": "grpc://peer1:7051", "eventURL": "grpc://peer1:7053" } ] } }, "credentials": { "hlfabric": { "admin": "adminpw" } } }' ```

torresjeff (Tue, 16 May 2017 19:44:56 GMT):
should i specify that in the startup script?

torresjeff (Tue, 16 May 2017 19:45:41 GMT):
ecause i tried setting `COMPOSER_CONFIG` in my `manifest.yml` but it was looking for the path in `keyValStore`

torresjeff (Tue, 16 May 2017 19:45:41 GMT):
because i tried setting `COMPOSER_CONFIG` in my `manifest.yml` but it was looking for the path in `keyValStore`

sstone1 (Tue, 16 May 2017 19:46:03 GMT):
right, so COMPOSER_CONFIG won't fix that

sstone1 (Tue, 16 May 2017 19:46:16 GMT):
it just saves you creating the connection profile in the Cloud Foundry file system

sstone1 (Tue, 16 May 2017 19:47:15 GMT):
if you want to use a LoopBack connector to persist the wallet

sstone1 (Tue, 16 May 2017 19:47:36 GMT):
you need to install a LoopBack connector, e.g. add `loopback-connector-mongodb` to your package.json

sstone1 (Tue, 16 May 2017 19:47:59 GMT):
and then add the following environment variable: ``` export COMPOSER_DATASOURCES=' { "db": { "name": "db", "connector": "mongodb", "host": "mongo" } }' ```

sstone1 (Tue, 16 May 2017 19:48:18 GMT):
You might need some additional configuration in there to point it to the right MongoDB instance though

sstone1 (Tue, 16 May 2017 19:48:53 GMT):
If you want to persist your wallet using anything that's not supported by a LoopBack connector, then you need to edit the `composer-rest-server` boot scripts

DennisM330 (Tue, 16 May 2017 19:49:16 GMT):
I was able to import the Swagger.json from a composer-rest-server configured for my business network into API Connect by simply downloading the JSON from the explorer/swagger.json and configuring the API to perform invokes of the appropriate REST endpoint. Would it be possible to use Kubernetes in front of a set of composer-rest-servers in Docker containers for load balancing?

torresjeff (Tue, 16 May 2017 19:49:28 GMT):
@sstone1 perfect, thanks!

sstone1 (Tue, 16 May 2017 19:50:59 GMT):
@DennisM330 yes, I have run a highly available REST server using nginx and 4 x REST server instances - using Docker - but assuming you know how to do something similiar in Kubernetes it should be fine

sstone1 (Tue, 16 May 2017 19:51:16 GMT):
The only problem is persisting the wallet in a highly available data source

sstone1 (Tue, 16 May 2017 19:51:29 GMT):
^ see above for that ;)

DennisM330 (Tue, 16 May 2017 19:58:27 GMT):
@sstone1 Thanks, I saw that above. Investigating an architectural pattern where an API Gateway might possibly front-end the composer-rest-server instances to provide security on the API such as OAuth, JWT, etc and Analytics

sstone1 (Tue, 16 May 2017 20:02:22 GMT):
cool, we do have some functionality checked in (but undocumented) that allows you to configure the REST server with one or more Passport strategies for authenticating the user.

sstone1 (Tue, 16 May 2017 20:02:39 GMT):
that allows each authenticated user to have their own wallet for their own blockchain identities

sstone1 (Tue, 16 May 2017 20:36:23 GMT):
@here just a reminder that we have a call on Thursday at 9am UTC (10am UK, 2:30pm IST, 5pm CST). This is the first time we've run a call at this time so a good chance to get involved and find out what is going on in the world of Composer. If you have any items you'd like to see added to the agenda, please let me know. We can cover existing features, new features, bugs, plans, contributing - anything! Also, if you'd be willing to talk about your experiences of using Composer, we'd love to hear from you, just let me know! It only has to be a couple of minutes and no slides/prep needed!

dwakeman (Wed, 17 May 2017 00:36:58 GMT):
Hello, everybody. I see some comments above about running composer-rest-server as a cf app in bluemix. I am interested in doing this, but don't quite understand how to do it. Do I just create an app with a package.json with a script (as mentioned) and all the right dependencies? This is just for dev/testing/demo purposes, not production so I don't need HA or anything. I have used composer-cli locally to deploy a network to the blockchain (0.61) service in bluemix and I want to run my rest server there. Any advice/pointers are greatly appreciated!

GururajL (Wed, 17 May 2017 01:56:39 GMT):
@davidkel , thanks, when composer deploys the chaincode to a multi-org channel, i assume that composer deploys only to the peers of one org, since we can only specify peers, msp of only one org in connection profile. Please correct me if i am wrong. is there a provision to specify multiple MSPs and peers belonging to different org in the connection profile? either thru UI or thru docker compose file.

dselman (Wed, 17 May 2017 06:38:36 GMT):
You should install an Ubuntu VM and run inside that.

davidkel (Wed, 17 May 2017 06:50:41 GMT):
@GururajL I would have thought that the typical use case scenario would be that organisations would only deploy to their own peers and not to other organisation peers and as such each org would have it's own unique connection profile. Also with the alpha 2 release of fabric you now need to be an admin of peer in order to be able to install chaincode onto the peer. Our deploy does an install followed by instantiate so need to look at whether it is necessary to split these out in order to support a multiple org scenario or whether both orgs can perform install/instantiate and still achieve the required result or whether only the one org needs to perform the instantiate. We don't support instantiate policies at this time and rely on the default.

GururajL (Wed, 17 May 2017 06:54:46 GMT):
@davidkel , install, instantiate should be fine the way you propose, but when a peer on which composer deploys the chaincode, sends a proposal, whom does it address to? does this peer in org1 send the transaction proposal to the peers in org2 as well?

GururajL (Wed, 17 May 2017 06:59:02 GMT):
is there a provision to specify peers when invoking any transaction, either in the ui or in the api?

davidkel (Wed, 17 May 2017 06:59:41 GMT):
@GururajL The install/instantiate or transaction proposal will be sent to all the peers listed in your connection profile.

davidkel (Wed, 17 May 2017 06:59:41 GMT):
@GururajL The install/instantiate or transaction proposal will be sent to all the peers listed in your connection profile. What still needs to be considered of course is whether you need to send to other peers outside your organisation for endorsement

GururajL (Wed, 17 May 2017 07:02:21 GMT):
yup!, if there is a need to send the proposal to peers in other org, is there a way to achieve it right now?

GururajL (Wed, 17 May 2017 07:02:37 GMT):
if not, would like to know the plan

davidkel (Wed, 17 May 2017 07:06:16 GMT):
@GururajL It's something we will test now alpha 2 is out to see what is required. For example do you have to have access to other orgs MSP in order to be able to send a transaction proposal ? If that's the case then there is going to have to be a lot of trust between orgs as well as sharing of cryptographic material.

GururajL (Wed, 17 May 2017 07:08:23 GMT):
assuming, we can keep the installing and initiating the chain codes across organisations, outside the scope, i guess there shd be provision to atleast send the transaction proposal to the peers in other org.

GururajL (Wed, 17 May 2017 07:09:41 GMT):
peers will then simply need to setup tls to exchange messages and no need for additional crypto material

davidkel (Wed, 17 May 2017 07:14:42 GMT):
@GururajL So I don't know at this point what is required. but I could see having to have a connection profile for install or install/instantiate and another one for transactions.

davidkel (Wed, 17 May 2017 07:15:50 GMT):
@GururajL the mspid in the connection profile needs to match the mspid of your user that you will interact with

GururajL (Wed, 17 May 2017 07:19:09 GMT):
@davidkel , ok

davidkel (Wed, 17 May 2017 07:21:38 GMT):
@GururajL This is still an area that needs more thought and work so really appreciate the questions and suggestions on this that you have and welcome any more thoughts in this area you have.

GururajL (Wed, 17 May 2017 07:23:10 GMT):
@davidkel , sure, thx much, in general, i would like to understand how a typical smart contract use case between 2 orgs can be met using composer

Is Fabric still running? What do you see if you run "docker ps"

tom.appleyard (Wed, 17 May 2017 08:18:07 GMT):
is the syntax for transaction logic definitions ```transaction ChangeOwner identified by txId { o String txId --> Marble marble --> Collector newOwner }``` `function changeOwner` or `function onChangeOwner` - I’m seeing examples of both

tom.appleyard (Wed, 17 May 2017 08:18:42 GMT):
also, how do you delete things from composer?

sstone1 (Wed, 17 May 2017 08:21:33 GMT):
`onChangeOwner` was the old syntax

sstone1 (Wed, 17 May 2017 08:21:48 GMT):
`anynameyoulike` with appropriate JSDoc comments is the new syntax

sstone1 (Wed, 17 May 2017 08:24:32 GMT):
you don't delete things from playground until @nkl199 finishes https://github.com/hyperledger/composer/issues/386

tom.appleyard (Wed, 17 May 2017 08:25:55 GMT):
So I don't have any JSDoc comments so presumably it is able to find it based on name?

sstone1 (Wed, 17 May 2017 08:26:19 GMT):
yeah but only when you use the `onTXName` syntax

tom.appleyard (Wed, 17 May 2017 08:26:36 GMT):
which I'm not using :/

tom.appleyard (Wed, 17 May 2017 08:26:52 GMT):
oh wait no yes I am

tom.appleyard (Wed, 17 May 2017 08:28:54 GMT):
```/** * Close the bidding for a vehicle listing and choose the * highest bid that is over the asking price * @param {org.acme.vehicle.auction.CloseBidding} closeBidding - the closeBidding transaction * @transaction */ function closeBidding(closeBidding) {``` Take this for example

tom.appleyard (Wed, 17 May 2017 08:29:01 GMT):
which is the 'apropriate' bit

tom.appleyard (Wed, 17 May 2017 08:29:19 GMT):
in the sense of which part of the comment ties the function to the transaction

sstone1 (Wed, 17 May 2017 08:29:32 GMT):
``` * @param {org.acme.vehicle.auction.CloseBidding} closeBidding - the closeBidding transaction * @transaction ```

tom.appleyard (Wed, 17 May 2017 08:30:21 GMT):
If I change it to this: ```/** * @param {org.acme.vehicle.auction.CloseBidding} args - the closeBidding transaction * @transaction */ function closeBidding(args) {``` Will it still work?

sstone1 (Wed, 17 May 2017 08:30:34 GMT):
should do

sstone1 (Wed, 17 May 2017 08:30:36 GMT):
no promises

sstone1 (Wed, 17 May 2017 08:30:43 GMT):
you don't like code comments?

tom.appleyard (Wed, 17 May 2017 08:31:13 GMT):
I don't mind comments, I just think it looks cleaner to have the first argument called args

dselman (Wed, 17 May 2017 08:33:02 GMT):

hi @dstarina - I would start your fabric-ca, orderers, peers nodes ..eg. docker-compose -f docker-compose.yml up --no-recreate -d ie if you want to start the existing containers (preserving what's there since your reboot).given that you've deployed your GS business network.

(using Hyperledger v1)

mahoney1 (Wed, 17 May 2017 12:19:11 GMT):
hi @dstarina for the v1.0 "Getting Started" - you would use the following update command (including enrollSecret below) for the Hyperledger Fabric v1.0 environment - composer network update --archiveFile digitalproperty-network@0.0.8.bna -*p hlfv1 --enrollId admin --enrollSecret adminpw*

mahoney1 (Wed, 17 May 2017 12:21:10 GMT):
ie `composer network update --archiveFile digitalproperty-network@0.0.8.bna -p hlfv1 --enrollId admin --enrollSecret adminpw` apols (ie ignore * above emboldening didn't work).

dselman (Wed, 17 May 2017 12:25:35 GMT):
@dstarina you should follow the quick start -- i.e. run npm install to start the containers.

dselman (Wed, 17 May 2017 12:25:47 GMT):
https://hyperledger.github.io/composer/installing/quickstart.html

dstarina (Wed, 17 May 2017 12:45:29 GMT):
@dselman - you mean even after it has been installed, after restart, I should run the npm install command to start them again? (sorry, I'm new to npm)

dselman (Wed, 17 May 2017 13:24:05 GMT):
The npm install script for getting started installs the software and then starts Fabric. If you want to just start Fabric you can run npm startHLF. Open package.json and you'll find the npm shortcuts for a bunch of useful scripts.

can you also show us the output of `ps -ef | grep composer-rest-server` when it is running

karthikworks (Wed, 17 May 2017 13:53:16 GMT):
@sstone1 The issue got solved once we upgraded to fabric 1.0

karthikworks (Wed, 17 May 2017 13:53:33 GMT):
@sstone1 thank you :thumbsup:

mahoney1 (Wed, 17 May 2017 14:00:17 GMT):
@dstarina In V1, it is admin that was enrolled (registered) earlier so as I mentioned it is `composer network update --archiveFile digitalproperty-network@0.0.8.bna -p hlfv1 --enrollId admin --enrollSecret adminpw` - your message indicates auth failure. One other thing, you should not be running as root (couldn't tell from your previous output)

@aashishshrestah how did you install the composer rest server ? where there any errors during the install process ? I noticed that everything is installed in usr/lib which usually only root has write access to. I wouldn't recommend installing or trying to run the composer tools as root. Far better to use a normal user.

mohamoud.egal (Wed, 17 May 2017 20:21:00 GMT):
@davidkel npm install -g composer-rest-server

davidkel (Wed, 17 May 2017 20:22:28 GMT):
@mohamoud.egal what userid are you doing that under and were there any errors during the install process ?

mohamoud.egal (Wed, 17 May 2017 20:22:41 GMT):
admin

mohamoud.egal (Wed, 17 May 2017 20:22:51 GMT):
I'm actually deleting & restarting the service

davidkel (Wed, 17 May 2017 20:26:54 GMT):
@mohamoud.egal The error described for composer-rest-server implies a problem with the installation around grpc

davidkel (Wed, 17 May 2017 20:26:54 GMT):
@mohamoud.egal The error described for composer-rest-server implies a problem with the installation around grpc, so when you installed the rest server, were there any error messages output ? Also it looks like node has been installed by root. You would be better off installing node as a normal user to avoid issues where you don't have write access the the /usr directory

mohamoud.egal (Wed, 17 May 2017 20:31:02 GMT):
@davidkel that's a good point. I didn't have any errors with the server

davidkel (Wed, 17 May 2017 20:40:49 GMT):
@mohamoud.egal only thing I can suggest would be to uninstall node and re-install it as a normal user and see if you can then install and run the rest server.

davidkel (Wed, 17 May 2017 20:41:32 GMT):
@mohamoud.egal as for your problem with playground, when you filled in the v0.6 information for bluemix did you ensure you copied in the certificate information and certificate path ?

mohamoud.egal (Wed, 17 May 2017 20:54:26 GMT):
it worked I'm now connected to Bluemix

mohamoud.egal (Wed, 17 May 2017 20:55:00 GMT):
my bluemix service was the problem so I deleted it & now I'm using a new service to connect @davidkel

@mohamoud.egal The error output could indicate a problem connecting to the fabric. How about trying a cli command such as network ping with the same profile to see if that works. There could be some sort of network problem or service problem if that fails as well and you are sure the connection profile is correct

mohamoud.egal (Wed, 17 May 2017 21:40:55 GMT):
I think the connection profile is correct, but it won't let me change it.

davidkel (Wed, 17 May 2017 21:45:34 GMT):
@mohamoud.egal The connection profile should be stored in your home directory under the `.composer-connection-profiles` directory. Hopefully you can find the right connection.json file to take a look. The directory you find this in is the name of the connection profile so you can do a `composer network ping` command and use the -p option to specify that connection profile

@here may i ask a dummy question. what is the main usage of fabric composer?

Jakeeyturner (Thu, 18 May 2017 09:45:49 GMT):
@arner I'm assuming you're using Playground to create the connection profile?

Jakeeyturner (Thu, 18 May 2017 09:46:06 GMT):
(use)

Jakeeyturner (Thu, 18 May 2017 09:51:31 GMT):
@bh4rtp Hyperledger Composer has some docs here which might be worth looking through - https://hyperledger.github.io/composer/introduction/introduction.html

davidkel (Thu, 18 May 2017 09:53:35 GMT):
@arner what level of composer are you running ? `composer --version`

arner (Thu, 18 May 2017 09:55:05 GMT):
0.5.5

tom.appleyard (Thu, 18 May 2017 09:55:27 GMT):
what's the difference between `factory.newInstance` and `factory.newResource`

davidkel (Thu, 18 May 2017 09:59:25 GMT):
@arner the connection profile format has changed since that release. I would recommend moving up to the latest version. In that version the definition of the peer event urls were defined in a separate property called 'events', and that version is unlikely to work well with multiple peer definitions

arner (Thu, 18 May 2017 10:01:09 GMT):
Oh sorry I thought I was on the latest -_-. Thanks

Hey @bh4rtp - as it happens, we're working to script out a short video for the Hyperledger website that will introduce the Composer Project. Whilst you're still new to Composer and figuring out what it's supposed to be used for, you'd be *perfect* to give us some feedback :) I've rushed together a quick draft here - sorry about the dodgy recording quality! There's an audio version, and then the full transcript in the description if you'd prefer to read it... https://soundcloud.com/edmoffatt/hyperledger-composer-video-script-draft-2/s-WSatY Would also welcome feedback from anybody here - how do you feel this does at describing what the project is about and why somebody would want to use Composer? Anything in there that you find confusing, or questions you still have afterwards (that you would expect a brief intro video to have covered)?

how to reset the composer playground ?

jtonline (Thu, 18 May 2017 11:13:25 GMT):
@vivekraut you could try using `localstorage.clear()` in your browser console. Wanting to reset the playground seems to have come up a few times so it would be useful to know the background in case there's something that could be improved in the future

Hi, I have a novice question I'd like help. But first, today is first time I try Composer and went through the getting started with digital property and sample asset tutorials with no hiccups - congrats on smooth onboarding experience :) I would like to know about channels with Composer. I have a PoC to do with edge cases, I require one public network with 3 peers/participants, and a separate private channel between each participant. The reason is for privacy of ledger at each peer. Is there an example of Composer defined business network with more than 1 channel I can look at? Perhaps I have wrong idea, should it be two defined business networks running at same time, or is this design pattern not applicable in Composer (ie. restricted to a single channel) Thank you for help, it's my first day to look at Composer and I have tried searching around, your help will guide and save me a lot of time I don't have right now :)

dselman (Thu, 18 May 2017 14:49:35 GMT):
A composer business network definition is deployed to a channel (the channel id is in the connection profile). So, each channel is independent, and can have the same (or different) definition deployed.

rfu2k (Thu, 18 May 2017 14:52:01 GMT):
thank you @dselman sounds like what I want to do is possible, with one composer network per channel. I just need to be able to call across them from same application. Your answer gives me confidence to continue, thank you again :)

@jinvanstee - we're not planning a release today, since the Consensus conference is next week, and there'll be a hackathon over the weekend making heavy use of Composer. We're "playing it safe" and not cutting a release until those activities are out of the way :)

jtonline (Thu, 18 May 2017 16:23:07 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=6MsLkwfdiLuXb7Awe) @vivekraut did you try clearing local storage? That's where the playground stores its wallet. (I've just posted a related answer on stack overflow http://stackoverflow.com/a/44053007/4218664 but let me know if that doesn't work.)

davidkel (Thu, 18 May 2017 16:29:53 GMT):
@SahilKapoor you can use composer on a fabric v1-alpha set up to use couchdb. There is nothing you need to do on the composer side if your fabric setup uses couch db. We don't exploit any of the features of using couch db currently but that is coming soon when composer will provide rich query support

davidkel (Thu, 18 May 2017 16:46:56 GMT):
@Dpkkmr the error message says it cannot connect to the local fabric ca server. If you still have the problem then it would be worth using docker to check the logs of that server, also try using docker-compose to stop and start the services (make sure you use the --no-recreate on up first to ensure it doesn't remove the current containers and recreate them). to see if it solves the problem (maybe it is a docker network problem). also try using network ping to see if you can communicate with the other fabric services as well.

Hi, When trying to deploy a *.bna file I'm getting below mentioned exception : For testing purpose, I have used basic sample network files. Attached the trace file. It will be really helpful if some one can help me resolve this issue or suggest a way to deploy a *.bna file. For deploying I'm using this command : "composer network deploy --archiveFile basic-sample-network.bna --enrollId WebAppAdmin --enrollSecret DJY27pEnl16d" Is there any change in the command which I need to do for V1.0? Unfortunately deploy from web is also failing for V1.0 :( Thanks in advance!

I have installed Composer and then Playground on the same system. I'm trying to connect Playground to Fabric v1, I copied the connection profile from hlfv1 folder and used _admin_ user (pw: _adminpw_) to connect. Seems to be stuck while connecting.

Hi guys, the composer cli is timing out when I try to deploy a compose instance, I’m getting no more debug information so I’ll just set out my connection profile, the command and versions of the modules if thats cool :) *Connection profile:* ``` { "type": "hlf", "membershipServicesURL": "grpc://localhost:7054", "peerURL": "grpc://localhost:7051", "eventHubURL": "grpc://localhost:7053", "keyValStore": "/Users/georgeormrod/.composer-credentials", "deployWaitTime": "300", "invokeWaitTime": "100", "networks": { } } ``` *Composer version:* ``` composer-cli v0.7.2 composer-admin v0.7.2 composer-client v0.7.2 composer-common v0.7.2 composer-runtime-hlf v0.7.2 ``` Command I’m using: `composer network deploy -a network.zip -i WebAppAdmin -s DJY27pEnl16d` There doesn’t look like theres any errors in the peer just seems to run the deploy command then stop before timing out :/

rodders1991 (Fri, 19 May 2017 12:18:01 GMT):

Hi, I'm playing with the http://composer-playground.mybluemix.net/. I added participant and the asset, but when I try to make a new transaction I got the error `Error: Object with ID 'assetId:3256' in collection with ID 'Asset:org.acme.sample.SampleAsset' does not exist` The asset id is the same as the asset I've just created. Any idea?

dselman (Fri, 19 May 2017 13:37:33 GMT):
The asset id is `assetId:3256` in your example. I suspect you should remove the `assetId:` prefix

That looks like a Hyperledger Fabric v0.6 profile, is that what you're trying to connect to? Or v1.0 ?

[ ](https://chat.hyperledger.org/channel/composer?msg=2H2ez862nTJnDofFB) @dstarina not sure you've had a response - but you should be able to work with the current (Fabric v1) connection profile (as currently ID admin) - and flip between v1 connection profile or browser connection profile in Playground and shows active profile. Don't need to use another user , no.

After watching the Introduction video, I noticed that there was a UI that Simon generated with the angular app generator that while he says "won't win any UI awards" is a clean start. All that it generates now is the rest API which is a bit sloppy for demonstration purposes. Is there any way to get this other UI from the introduction?

Jakeeyturner (Fri, 19 May 2017 15:52:11 GMT):
@jarroyer If you go to the generated applications directory and run `npm start`, that'll start the REST API server and will webpack the front-end. So if you navigate to `http://localhost:4200` you'll see the front end.

Jakeeyturner (Fri, 19 May 2017 15:54:21 GMT):
@karthikworks Perhaps take a look here: http://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service Double check your ports are correct as well, as in that stackoverflow link, the ports are different to what you have configured in your connection profile :)

@Jakeeyturner I just get a blank page that says "Invalid Host header". The app is run on an AWS computer and I navigated (from a different computer) to :4200.

@SahilKapoor you didn't specify a profile to use for the network deploy command so it uses defaultProfile which is a hlf v0.6 profile. If you followed our getting started or one click install guides then as part of creating a development fabric runtime to work with, a profile called hlfv1 is also created to work with that runtime. You need to specify this profile for example `composer network deploy -p hlfv1 -a marbles-network.bna -i admin -s adminpw`

Connection.json is the one generated when deploying fabric v1 , right?

2. connection.json is the one generated when deploying fabric v1 , right?

dselman (Sat, 20 May 2017 09:46:18 GMT):
You need to follow the HLF v1 quick start: https://hyperledger.github.io/composer/installing/quickstart.html

dselman (Sat, 20 May 2017 09:46:28 GMT):
That will create the connection profile for you

SahilKapoor (Sat, 20 May 2017 09:51:21 GMT):
@dselman , that is done.. I was able to deploy the bna file as well.. So those things are already deployed in my ubuntu server. I was trying to create rest service from windows . I think create rest api should work from windows as the connection profile( C:\Users\Home\AppData\Roaming\npm\node_modules\composer-rest-server\server\config.js) contains the IP address of the server where fabric is installed. Let me try and paste the connectionprofile in windows and try again

SahilKapoor (Sat, 20 May 2017 09:51:53 GMT):
Is this doesn't work then I will go for creating rest service from ubuntu where fabric is installed

dselman (Sat, 20 May 2017 10:16:19 GMT):
You won't be able to run the rest server on Windows because grpc doesn't work -- which is the protocol the client uses to communicate with Fabric.

A question, how can i see all transactions ? If I can, filter can be applied to api like get all transaction for an asset id or for an userid? Can this be achieved in some other way like , java sdk for fabric or some cli commands or by composer somehow?

SahilKapoor (Sat, 20 May 2017 13:18:22 GMT):
So in marble example , transaction module only one api to perform transaction

SahilKapoor (Sat, 20 May 2017 13:18:22 GMT):

SahilKapoor (Sat, 20 May 2017 13:19:44 GMT):
Simplest approach is to persist all transactions at my end but then it does not serve the prupose.

dselman (Sat, 20 May 2017 13:29:10 GMT):
This code is not yet in a release (it should go out next Thurs). Too use it you will have to `npm install -g composer-rest-server@unstable` and also `npm install -g composer-cli@unstable`

dselman (Sat, 20 May 2017 13:29:57 GMT):
You will need to redeploy your network using the unstable composer-cli for the unstable composer-rest-server to be able to connect to it.

Hi, I struggle with filtering on the data model when using loopback Explorer. According to docs http://loopback.io/doc/en/lb2/Where-filter.html#operators there are number of operators but when I use something like {"where": {"keywords": {"inq": ["foo", "bar"]}}} I get 500 Err "invalid arg specified: [object Object]". Only a simple where clause works. My questions are, if anyone seen this before and aren't these operators supported with the models in composer? I'm using hlfv1.0.

sstone1 (Sun, 21 May 2017 17:04:18 GMT):
@Pasteis those are not currently supported. You can only query based on the ID of an asset at the moment.

sstone1 (Sun, 21 May 2017 17:04:54 GMT):
We are implementing support for complex query and exploting the Fabric v1.0 CouchDB support, and when that is available we can enable all of the LoopBack query functionality.

tennenjl (Mon, 22 May 2017 01:21:27 GMT):
Hi, I was curious on how the composer ACL capabilities work when it comes to restricting read access to an asset or a property of an asset. My understanding is that Composer supports this, but how would this work? if I have an asset which contains an array of it's transaction history and I want to restrict access to the transaction history to the owner of the asset (where the owner of the asset can change over time), would I be able to restrict access? Also when we work with composer, we are creating query operations where we are not altering an asset, are those treated like any other transaction?

Hello I found the composer project exciting and will like to contribute to it. I have setup the dev environment and was going through the code, i was able to link the dots till it reached the invoke Chaincode step. From there onwards i didn't make out much on how the actual runtime engine written in js mapped to the chaincode written in 'go'. Are there any design docs i can go through in order to better understand the implementation of composer?

@davidkel I have installed hyperledger/composer-playground via docker - how do I check the version?

davidkel (Mon, 22 May 2017 13:35:38 GMT):
@dstarina That's an excellent question and is actually not easy to do (although it should be) the following command will do it ``` docker exec composer-playground cat /usr/local/lib/node_modules/composer-playground/package.json | grep composer-playground@ ``` but I think I know the answer it will give :-) and as such the answer is the docker version of composer-playground cannot connect to hlfv1

dstarina (Mon, 22 May 2017 13:45:19 GMT):
@davidkel the command won't work, but since you already gave me the answer ... is the npm version the same?

davidkel (Mon, 22 May 2017 13:49:23 GMT):
@dstarina the command should work is you have the container created with the name composer-playground. If you do a `docker ps -a` what does it show ?

davidkel (Mon, 22 May 2017 13:50:00 GMT):
for example my output is ``` "raw": "composer-playground@0.7.2", "_from": "composer-playground@0.7.2", "_id": "composer-playground@0.7.2", "raw": "composer-playground@0.7.2", "_spec": "composer-playground@0.7.2", ```

@dstarina but it was setup through our quick start which doesn't enable TLS on that fabric runtime. The certificate information is needed only if TLS is enabled

Hi @jdockter what platform are you on, Windows, Linux or Mac? I know for sure it works on Windows, but it's possible that there is a problem on Linux or Mac? Also, can you confirm if it underlines "errors" in red (which is should ) to confirm if the problem is with Highlighting only or with Validation as well? Finally If you could raise me an issue I'll take a look...

[ ](https://chat.hyperledger.org/channel/composer?msg=hbbynGzHS52XWhDTt) @pranavkaushik you don't need to define registries -- a registry is automatically created for each modelled type

dselman (Mon, 22 May 2017 18:58:13 GMT):

Hi, i'm exploring the "security" feature of the REST server. Is there any documentation available about how this works? After enabling it, all my requests are rejected with error "AUTHORIZATION_REQUIRED"? how can i generate an access token? thanks!

jdockter (Mon, 22 May 2017 19:01:38 GMT):
@mgk Linux Ubuntu 14.04... no highlighting on any .acl file

mgk (Mon, 22 May 2017 19:02:14 GMT):
k, thanks for the confirmation. Does it validate the file though?

mgk (Mon, 22 May 2017 19:02:14 GMT):
k, thanks @jdockter for the confirmation. Does it validate the file though?

mgk (Mon, 22 May 2017 19:03:04 GMT):
for example, type "rulez" instead of "rule" to force a parse error - you should see an error in the errors pane?

dselman (Mon, 22 May 2017 19:03:06 GMT):

dselman (Mon, 22 May 2017 19:50:24 GMT):
@mgk yes

DennisM330 (Mon, 22 May 2017 19:54:04 GMT):
@deslman Thanks, trying to create a connection profile and include the certificate which needs to wrap in the file. Any good way to reformat the cert file when you download it?

mgk (Mon, 22 May 2017 19:57:44 GMT):
Thanks for the confirmation @dselman . So we can confirm that Windows and Mac are fine with ACL files, but there is a problem with the Highlighting on Ubuntu. @jdockter if you could please raise an issue for this on the composer-vscode-plugin repo I'll take a look, thanks...

abcoathup (Tue, 23 May 2017 06:01:53 GMT):
Thinking about security, not sure if there is some documentation covering this, or how much is about Fabric rather than Composer If assets and transactions have ACL's to prevent a competitor participant from viewing, what access can a competitor have to assets and transactions owned by another participant? Can they access the underlying Fabric ledger to view assets/transactions? Can they view the transaction processing function? Can they view the logs of the transaction processing function? How secure are ACLs? Thanks

davidkel (Tue, 23 May 2017 07:18:07 GMT):
@deepakvparmar the error you posted shows that there is a version of node installed and it is a very old version. Given it's location as well it looks like it is a version of node installed from the distribution package manager. Could you try issuing `sudo apt-get purge -y nodejs`

[ ](https://chat.hyperledger.org/channel/composer?msg=ngNBjpadA2JvuuXzD) @dselman Nope. I have tried it by shutting down rest api first then generate the application and also the other way where rest api is up and running before angular application is generated. Every time it hangs at that point .

pranavkaushik (Tue, 23 May 2017 07:41:14 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=jGuvf8pRobvYZspJ3) @davidkel if you look at this link http://hyperledger-fabric.readthedocs.io/en/latest/case_for_fabric.html?highlight=multiple%20channel, which says "One of Fabric’s key innovations is the ability to run multiple Channel s on each network. This is how a network can conduct both highly confidential bilateral transactions and multilateral, or even public, transactions in the same solution without everyone having a copy of every transaction or run the code in every agreement". Now my question is around whether composer supports defining which transactions should occur on what channels

davidkel (Tue, 23 May 2017 08:00:56 GMT):
@pranavkaushik With composer, business networks are deployed to a specific channel. When you transact with that business network you only interact on that channel.

[ ](https://chat.hyperledger.org/channel/composer?msg=LuZu6RZWRxsRgdSCo) @SahilKapoor I think that the Angular generator currently assumes that the composer-rest-server is generating routes with namespaces.

Hi, this is maybe more a general Fabric question, but what is the best way to see what transactions have been created by Composer on the underlying Fabric? I notice when I deployed my new bna file to Fabric, the peer reported 2 new transactions but I'm not sure how I can view these to see what has been done as part of the deployment. ``` 2017-05-23 08:38:57.595 UTC [kvledger] Commit -> INFO 04d Channel [mychannel]: Created block [9] with 1 transaction(s) 2017-05-23 08:38:58.577 UTC [kvledger] Commit -> INFO 04e Channel [mychannel]: Created block [10] with 1 transaction(s) ```

no worries. I believe that in v0.6 it would have been easier though https://fabric-sdk-node.github.io/Chain.html#queryTransaction__anchor does indicate that you can query for a specific transaction if you have the id

dselman (Tue, 23 May 2017 09:42:47 GMT):
Something like the HLF Blockchain Explorer would be best. I'm not sure that has been ported to HLF v1 yet.

@deepakvparmar there could be a couple of reasons for this, assuming you aren't using sudo to run npm (as this will cause problems). The other reasons are 1. The version of python installed is not v2. what get's output when you do `python -V` ? Also you need to have gcc and make installed as well

An user has been issued an Identity after that he tries to login with userID - and is able to login because the wallet contains his certificate. Now our question is can anyone with his userID login ?

@deepakvparmar could you check to see of grpc was built. You find it in the lib directory of the level of node you are using, so for example on my machine the node version I am using is installed at ``` /home/ubuntu/.nvm/versions/node/v6.9.5 ``` So the grpc binary would be in ``` /home/ubuntu/.nvm/versions/node/v6.9.5/lib/node_modules/composer-cli/node_modules/grpc/src/node/extension_binary ``` and is called grpc_node.node

@rfu2k Are you using the one-click install capabilities or are you managing the docker containers yourself ? Because that problem is the fact that playground cannot communicate with your fabric and it could be done to network isolation between docker containers.

thanks @davidkel i had an existing network (1.0 alpha) and used npm install of composer-playground and setup the connection profile, it was working about 4 hours ago, and past couple of days, no idea what has changed since.. trying not to reinstall everything again if there's something stupid ive done that's causing it and easier to reverse.. :)

rfu2k (Tue, 23 May 2017 15:31:51 GMT):
didn't have any luck fixing the error, deleted the containers and recreated the network and back up running again

@rfu2k I wonder if there was a problem with fabric, perhaps specific to running in a docker environment. I have seen other reports of something similar, but it was the initial alpha release. There is a new alpha2 release which we are working on and hope to release soon.

Can I run composer-rest-server as a cloud foundry app in Bluemix? I want to have my rest api server that is pointing to my Bluemix instance of blockchain to also be hosted as a bluemix app, rather than running it locally. Is it as simple as copying the /usr/local/lib/node_modules/composer-rest-server directory on my local machine and pushing it to bluemix with an appropriate manifest.yml file?

[ ](https://chat.hyperledger.org/channel/composer?msg=j3cWvjZQxmi3rNbi8) @sanjay-saxena no there's no API to return the number of items in a registry. I don't recommend doing what you propose because on HLF v1 under load you will get optimistic transaction failures as multiple peers will be getting the size of the registries and there is no global lock. So peer0 may get a different value from peer1, which will cause your transaction to rollback. You need to be able to deterministically get the next id from the incoming transaction, which usually means computing it on the client.

@deepakvparmar if everything is running inside the vagrant box there shouldn't be an issue are you trying to connect to something from outside the vagrant box ?

deepakvparmar (Wed, 24 May 2017 09:51:58 GMT):
@davidkel : Using TestXenial only, but modified Vagrantfile to add some more ports. In fact, I was getting same error for 4200 port without modifying Vagrantfile as well.

davidkel (Wed, 24 May 2017 09:55:59 GMT):
@deepakvparmar If you only want to connect out from the box then you don't need those ports exposed and you should be able to communicate with bluemix fine. If you need to connect in (eg you run the rest server and want to browse to it from your machine) then you need to expose the ports. I've no idea why it's not able to expose the ports but I do know that there are problems with Vagrant 1.9.4 so try an earlier version such as 1.9.1

deepakvparmar (Wed, 24 May 2017 09:58:34 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Gbygt7bvofgx4F7L9) @davidkel : I am having 1.9.3 Vagrant version. I have not faced this issue before as I could able to create Vagrantfile for trusty64 and forwarded ports in past.

@davidkel I'm on macOS Sierra 10.12.4, though it's a corporate image so may have had it's networking nobbled/gubbins interfered with. Also it is Fabric 1.0 alpha I'm using, looking forward to the alpha2 release of Composer :)

davidkel (Wed, 24 May 2017 10:31:35 GMT):
@rfu2k Thanks for that. Docker on Mac is more complex as what it actually does is run a virtual machine with Alpine linux in a open source hypervisor implementation ported from netbsd, so there is a good chance this is related to this hypervisor environment so likely to be a docker issue.

@Fanarito composer currently supports alpha1 only. Looking at the yeasy docker file it relies on testchainid which although appears to still work, isn't guaranteed and in fact the fabric team want to remove it. Can you provide more details on why you had problems with the running of the composer-sample-applications-hlfv1 ?

I want to build a hierarchical data model which looks like this: N Items (indexed by SGTIN numbers) -> packed into a Case (indexed by SSCC) M Cases (indexed by SSCC numbers) -> packed into a Pallet etc. Key is that I need to track items through their life cycle even if they are packed in cases or pallets, hence I need the references. The way I have implemented it so far is as follows: CTO file: ``` … abstract asset TransportAsset identified by SSCC { o String SSCC o AssetStatus status o String location optional } asset Case extends TransportAsset { o AddItemToCase[] items optional } … transaction AddItemToCase identified by transactionId { o String transactionId o String sgtin --> Case case0 } ``` The resulting items embedded in the case are shown below. My question is if this is the correct approach to establish hierarchies or if there is another concept. If so, is there any example available? get command: http://fabriccomposer.jje.zc2.ibm.com:3000/api/net.biz.PropertyNetwork.Case Reply: ``` [ { "$class": "net.biz.PropertyNetwork.Case", "items": [ { "$class": "net.biz.PropertyNetwork.AddItemToCase", "transactionId": "b8d3b8c2-56b9-4bef-8afe-070778464941", "sgtin": "7680336987654.1", "case0": "resource:net.biz.PropertyNetwork.Case#200.3", "timestamp": "2017-05-24T12:26:25.604Z" }, { "$class": "net.biz.PropertyNetwork.AddItemToCase", "transactionId": "f06b1975-2e83-4738-a0e0-dc375acffdb0", "sgtin": "7680336987654.2", "case0": "resource:net.biz.PropertyNetwork.Case#200.3", "timestamp": "2017-05-24T12:26:28.476Z" }, { "$class": "net.biz.PropertyNetwork.AddItemToCase", "transactionId": "e1c73eb0-504a-4fcf-99cb-e7357b4f6b56", "sgtin": "7680336987654.3", "case0": "resource:net.biz.PropertyNetwork.Case#200.3", "timestamp": "2017-05-24T12:26:31.419Z" }, { "$class": "net.biz.PropertyNetwork.AddItemToCase", "transactionId": "68e5363e-1b70-4605-b037-56cf5fd400f6", "sgtin": "7680336987654.4", "case0": "resource:net.biz.PropertyNetwork.Case#200.3", "timestamp": "2017-05-24T12:26:34.277Z" } ], "SSCC": "200.3", "status": "PACKED" }, { "$class": "net.biz.PropertyNetwork.Case", "SSCC": "200.2", "status": "COMMISSIONED" }, { "$class": "net.biz.PropertyNetwork.Case", "SSCC": "200.1", "status": "COMMISSIONED" } ] ```

@nkl199 , thanks for the pointer. However I didn't really see the concept of a hierarchy there. Also, is there a good description available for the "concepts"?

JennFoley (Wed, 24 May 2017 13:57:29 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=5wXg6JoJmXFYDW42Y) @davidkel Thanks! That helps!

nkl199 (Wed, 24 May 2017 14:05:27 GMT):
HI @jje, a concept is essentially a class that has no id. Whereas Assets, participants etc require an identifier, concepts do not. If you are not considering the lifecycle of the items, then it would be of use to you... however if you are considering the lifecycle of items and crates, then you will need to consider both items and crates as assets.

jje (Wed, 24 May 2017 14:08:05 GMT):
@nkl199: Thanks for the clarification, in this case I need to use assets...

nkl199 (Wed, 24 May 2017 14:22:48 GMT):
@jje whilst it would depend on exactly what you wish to determine wrt items/crates, the animal-tracking sample might be more useful - in that one a business (Asset) has a relationship to an array of animals (assets)

jje (Wed, 24 May 2017 14:27:56 GMT):
@nkl199 : I have seen this and that is certainly closest to what I have in mind since animals are transferred to the receiver... I was however wondering if there is a more direct map of an example to what I have in mind since there are many examples (in logistics, supply chain, tracking of assemblies in planes, etc.) where these hierarchical asset relations exist.

nkl199 (Wed, 24 May 2017 14:33:47 GMT):
I don't believe there are (yet) it would certainly make a good sample - the current ones are all more concrete and consequently applied to a specific realm

nkl199 (Wed, 24 May 2017 14:34:45 GMT):
would you find the samples more useful if they were slightly more open ended, or perhaps even more granular?

nkl199 (Wed, 24 May 2017 14:47:37 GMT):
is this a reference to a participant within a transaction?

Fanarito (Wed, 24 May 2017 14:47:59 GMT):
yes

nkl199 (Wed, 24 May 2017 14:48:25 GMT):
that is allowed - and is in the vehicle lifecycle sample

Hi, I am currently struggling with writing model/lib files for my network. The idea is to have network with 2 user types (Regulator, who can see everything and Owner, who can see some properties of all registered assets and can register his own assets). The assets should only be registered by and to the Owner and should not be changed later. So I have something like this and I know that js-file is not fully correct. Anyone who could help? (hlfv1, composer-playground Mac, all running smoothly). Thanks!

DrTES (Thu, 25 May 2017 00:47:03 GMT):
Yes, I did look at quite some of the models. What is puzzling me is that there is a string in cto "o String newValue", which then is being processed in js-file and the state of the asset is being update on the blockchain (as far as I understand). I dont have this in my network - the Owner needs to register an asset ( i can do that with "create new asset") and have a proof registering it without being able to change the record anymore ( I assume I should do "submit Transaction" for that).

tennenjl (Thu, 25 May 2017 00:50:52 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Lz7pyJN8GwcLcNSHz) @dselman Thanks. We were looking at a use case where ownership of some reference data is going to get transferred from one org in a network to another org in a network, where we may need endorsement signature from a peer from each org. I still am not completely clear on how the default endorsement policy works, but It seemed as if only required a single signature, which might not be sufficient for many use cases. I've posted a question on the fabric-questions channel to get confirmation. Thanks again.

tennenjl (Thu, 25 May 2017 01:01:28 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=iXfBwP4yjNecXrZHG) @jeffgarratt Hi Jeff, I was wondering if we ever determined what the default behavior was for the endorsement policy. The way I read the docs, that @davidkel referenced it seemed like only one signature was required, I posted this question on fabric-questions, but I saw the thread here and decided to ask. Thanks!

As per the transaction flow that is done on the fabric given here, http://hyperledger-fabric.readthedocs.io/en/latest/txflow.html there are 6 steps that happen before the transaction gets committed to the ledger. There is endorsing, validation and execution of the transaction that takes place. How does all these steps map to the composer when i submit a transaction? I know there are default peers and orderers that get created when a network is deployed but i am unable to figure out how each step maps to the actual fabric transaction flow. Any insights will help.

rfu2k (Thu, 25 May 2017 08:30:42 GMT):
@davidkel one example of an endorsement that is being requested on a project I'm associated with, is a participant owned peer requiring endorsement of a transaction of an independent peer. The independent peer would kind of act as a 3rd party notary Thinking of an example off top of my head - if you have a car auction, with private encrypted bids, you may want to run a separate channel with the seller peer and auction peer (unencrypt bids client side, and pass the bids unencrypted to the contract and keep the data out of the common ledger). If you can invoke transaction to choose best bid, and have it endorsed by the auction peer it may act as a kind of proof that same result was calculated on both the seller and independent broker

@ibmamnt I have updated the issue with links to the Fabric issues that are the root cause. I don't think there's anything we can do about this at the Composer level. An application using base Fabric would show the same symptoms.

ibmamnt (Thu, 25 May 2017 08:43:39 GMT):
@dselman Thanks ! I have updated the comment too. Basically there is a work around for now, and personally dev team consider the possible work around, since this is show stopper class defect, and can not release product into the production. (Note that Bluemix does not provide test service for v1.0 except HSBC beta which can be expensive after GA for just testing).

davidkel (Thu, 25 May 2017 08:49:22 GMT):
@ibmamnt I don't think there is anything composer can do about the grpc timeout. It has to be handled by the fabric node sdk. I see you have raised a jira relating to it. I would highly recommend changing it's status from high to highest and also try to see if they will do anything for the v0.6 implementation

ibmamnt (Thu, 25 May 2017 08:56:06 GMT):
@davidkel I understood. For now, we are working around the problem by simulated "keep alive". That is, try to connect to Fabric within 3 minutes from application side by "ping" function which invokes "ping" query function inside chaincode.

@rama_rahul composer won't be able to support that fabric environment. Composer will only work with the alpha1 release of hyperledger fabric at the moment.

@rama_rahul in your previous screen shots it looks like you were targetting v0.6 fabric with both the results of the ps and the composer commands you were trying

Hi, I'm trying out a REST (post) call to create a Vehicle in the Vehicle Lifecycle Network sample. The Swagger describes the following for the input: { "$class": "org.vda.Vehicle", "vin": "string", "vehicleDetails": { "$class": "org.vda.VehicleDetails", "make": "string", ... I provided the following: { "$class": "org.vda.Vehicle", "vin": "1234", "vehicleDetails": { "$class": "org.vda.VehicleDetails", "make": "Fiat", ... I got back a 200 OK with this response: { "$class": "org.vda.Vehicle", "vin": [ null, null ], "vehicleDetails": { "$class": "org.vda.VehicleDetails", "make": "Fiat", ... For some reason the vin appears to be an array of nulls. That doesn't seem right to me. Is this what is expected? When I do a get to retrieve the vehicle everything looks fine and the vin is filled out correctly.

davidkel (Thu, 25 May 2017 12:37:33 GMT):
@rama_rahul so maybe the reason the v0.6 fabric (which you were following via the quickstart) failed to start correctly was you had other stuff running and there was a port conflict ?

@rama_rahul I recommend you uninstall node and re-install node under a general userid. don't install it as root and start again. It's far easier than trying to make it work the way you have installed it.

SanketPanchamia (Thu, 25 May 2017 13:32:42 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=6GEeJkgrTw2wPfPen) @jorgedr You can check the composer sample applications.

davidkel (Thu, 25 May 2017 13:39:40 GMT):
@ianco so couple of things if you don't specify a connection profile a v0.6 one is created and used called defaultProfile which causes the errors you are seeing. If you follow the quickstart then we suitable hlfv1 profile is created for you which will map to the fabric runtime we setup. When you say built from source and you say alpha do you mean alpha 1 or alpha 2 ? composer doesn't work with alpha2 at the moment

ianco (Thu, 25 May 2017 13:41:57 GMT):
@davidkel thanks for the quick reply! I'll confirm the connection profile (I thought I did the quick start but may have missed a step) and I'll also check the version I'm running (probably alpha 2 ...)

tennenjl (Thu, 25 May 2017 14:30:09 GMT):
@davidkel Think I just got the answers from @jeffgarratt regarding default endorsement policies... The thread is in the #fabric-questions channel

davidkel (Thu, 25 May 2017 14:34:27 GMT):
@tennenjl So that hasn't really cleared things up for me. We really need more detailed documentation regarding how validating of endorsements are done. I'm also intrigued about what he meant that peers don't correlate 1-1 with MSPs

jeffgarratt (Thu, 25 May 2017 14:36:25 GMT):
@davidkel my mud was not clear :)

tennenjl (Thu, 25 May 2017 14:36:59 GMT):
@davidkel If I understood it correctly, then depending on the org the peer is associated with, it can have its own msp, so there isn't a 1-1 between peer and MSP

tennenjl (Thu, 25 May 2017 14:37:09 GMT):
will defer to @jeffgarratt

jeffgarratt (Thu, 25 May 2017 14:37:28 GMT):
@tennenjl correct. But all 4 peers in a scenario could belong to the same MSP

jeffgarratt (Thu, 25 May 2017 14:37:43 GMT):
it is probably clearly to always include the tuple of (peer,org)

jeffgarratt (Thu, 25 May 2017 14:38:01 GMT):
though a peer by config belongs to a single org wrt to signing

jeffgarratt (Thu, 25 May 2017 14:38:36 GMT):
I was referring to how @tennenjl was utilizing the word peer wrt to endorsements, when it is clearer to refer to principals

davidkel (Thu, 25 May 2017 14:38:39 GMT):
@jeffgarratt My understanding is that a peer will have a single msp definition is it possible for a peer to have multiple ?

jeffgarratt (Thu, 25 May 2017 14:38:44 GMT):
well, precise, maybe not clearer

jeffgarratt (Thu, 25 May 2017 14:39:06 GMT):
correct, it has a single MSP identity wrt to signing

jeffgarratt (Thu, 25 May 2017 14:39:28 GMT):
though theoretically their cert could have been signed by multiple MSPs

jeffgarratt (Thu, 25 May 2017 14:39:56 GMT):
see the possible nuance wrt to MSP

jeffgarratt (Thu, 25 May 2017 14:40:24 GMT):
this is where PKI concepts can be a bit confusing and complicated

jeffgarratt (Thu, 25 May 2017 14:40:53 GMT):
my assumption is that @davidkel needs a more precise understanding of endorsement with respect to deployment of the composer chaincode

jeffgarratt (Thu, 25 May 2017 14:41:42 GMT):
and perhaps the internal machinations of 0.6 may overlap to some degree with the endorsement policies of v1

davidkel (Thu, 25 May 2017 14:41:48 GMT):
@jeffgarratt so with respect to validation in order for a peer to validate doesn't it need access to crypto material from other msps in order to validate endorsements if that endorsement was signed by another msp (unless of course that peers msp identity has commonality with the other msps that facilitate it being able to validate with requiring extra crypto material ?)

jeffgarratt (Thu, 25 May 2017 14:42:12 GMT):
Correct, the localMspConfig includes CAs

jeffgarratt (Thu, 25 May 2017 14:42:23 GMT):
as well as the MSPConfig for the channel

jeffgarratt (Thu, 25 May 2017 14:43:55 GMT):
so you would have to consider multiple layers. The first being the install and the instantiate of the composer chaincode.

davidkel (Thu, 25 May 2017 14:43:56 GMT):
@jeffgarratt ok, so the peer has access to MSP material when it joins the channel

jeffgarratt (Thu, 25 May 2017 14:44:13 GMT):
correct, in the MSPConfig of the ApplicationGroup

jeffgarratt (Thu, 25 May 2017 14:44:13 GMT):
correct, in the MSPConfigs of the ApplicationGroup

jeffgarratt (Thu, 25 May 2017 14:44:42 GMT):
those were chosen and configured on channel definition

jeffgarratt (Thu, 25 May 2017 14:44:55 GMT):

rfu2k (Thu, 25 May 2017 15:10:32 GMT):
@nehalshah50 do you need something in particular? I have been contemplating the idea of 'attaching' a doc to assets by storing a IPFS hash to the document as a string in the asset instance, just a field with the key of 'attachment' or whatever, like any other field. I guess you wouldn't want to attach actual files or large entities to the ledger but a pointer to the real thing.

nehalshah50 (Thu, 25 May 2017 15:27:54 GMT):
@rfu2k Basically there could be many use cases like Letter of Credit where you would need to upload / download attachments for any changes to attachments should also be done through a new transaction. What I am thinking /suggesting is that Composer should support a special data type called 'Attachment' so that way it know that this value of such datatype requires system to allow upload/download of files. Files itself can be stored somewhere in fabric may be outside of the block. But its hash needs to be tracked within block as key/value pair or something. Watch one blockchain based demo here for the Letter of Credit usecase. https://www.youtube.com/watch?v=5wkkIaemSw4

dselman (Thu, 25 May 2017 19:33:12 GMT):
@dwakeman is that the right enrollment id and secret for your bluemix instance?

dwakeman (Thu, 25 May 2017 19:33:34 GMT):
Yes. got them out of the Service Credentials in the dashboard

dselman (Thu, 25 May 2017 19:33:38 GMT):
(start with the simple stuff first!) ;-)

dwakeman (Thu, 25 May 2017 19:33:47 GMT):
I've tried both admin and WebAppAdmin

dwakeman (Thu, 25 May 2017 19:34:32 GMT):
I had a number of issues building my docker container, so I am worried that perhaps I don't have the right prereqs or something.

dselman (Thu, 25 May 2017 19:34:48 GMT):
did you put the BMX certs into your connection profile?

dwakeman (Thu, 25 May 2017 19:34:54 GMT):
yes

dwakeman (Thu, 25 May 2017 19:35:12 GMT):
i copied the connection.json from my mac into my ubuntu container

sanjay-saxena (Thu, 25 May 2017 19:35:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=HdPJ2aYjSsGpoHhhP) @nkl199 -- Does 0.7.3 support Hyperledger Fabric 1.0.0-alpha2?

dselman (Thu, 25 May 2017 19:35:54 GMT):
@sanjay-saxena no -- it is still on Alpha1

sanjay-saxena (Thu, 25 May 2017 19:36:19 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=qDMA8YWjzbs7xcvv7) @dselman -- thx!

dselman (Thu, 25 May 2017 19:36:22 GMT):
we are working on the port to Alpha2 -- we deal with the Fabric API breakage so you don't have to... ;-)

dselman (Thu, 25 May 2017 19:36:59 GMT):
@dwakeman so exactly the same connection profile works on Mac and doesn't work on Ubuntu?

dselman (Thu, 25 May 2017 19:37:07 GMT):
That's a new one on me...

dwakeman (Thu, 25 May 2017 19:37:11 GMT):
yes

dwakeman (Thu, 25 May 2017 19:38:02 GMT):
lucky me that I found a new way to break something.

dwakeman (Thu, 25 May 2017 19:38:09 GMT):
:sunglasses:

dselman (Thu, 25 May 2017 19:38:29 GMT):
location of the certs dir?

dselman (Thu, 25 May 2017 19:38:46 GMT):
did you modify that in your connection profile

dselman (Thu, 25 May 2017 19:39:07 GMT):
You are on v0.6?

dwakeman (Thu, 25 May 2017 19:39:51 GMT):
I got that from my service credentials. /certs/peer/cert.pem. yes on v0.6. Does that directory need to exist in my docker container?

dwakeman (Thu, 25 May 2017 19:43:37 GMT):
I put the BMX certs in the connection.json. "certificate" and "certificate2" I don't have that directory.

dwakeman (Thu, 25 May 2017 19:45:03 GMT):
My container does run as root, so I changed the keyValStore to "/root/.composer-credentials". Should I switch to a non-root user?

nehalshah50 (Thu, 25 May 2017 19:57:14 GMT):
Does anyone know why the playground doesn't allow to save a new script file? Every time I create a new script file and then try to save the script file disappears. Also why it does not allow to define you own namespace?

nkl199 (Thu, 25 May 2017 20:12:20 GMT):
@nehalshah50 i'm having a look at this one now

dselman (Thu, 25 May 2017 20:21:18 GMT):
@nehalshah50 are you on the (latest) 0.7.3?

dselman (Thu, 25 May 2017 20:24:13 GMT):
@dwakeman the fact that is works on Mac but not on Linux is very odd.

dselman (Thu, 25 May 2017 20:25:08 GMT):
@dwakeman this path would have to exist on the client side: ` "keyValStore": "/home/composer/.composer-credentials", `

nkl199 (Thu, 25 May 2017 20:25:25 GMT):
i'm on linux and can confirm. and export retains all the files as per the playground

dwakeman (Thu, 25 May 2017 20:26:04 GMT):
@dselman does it have to be the user `composer`? it is running as root and I have it set to `/root/.composer-credentials`

dselman (Thu, 25 May 2017 20:26:13 GMT):
@nehalshah50 it won't save (actually deploy is the right word...) the business network if it has errors.

dselman (Thu, 25 May 2017 20:26:52 GMT):
as long as the directory exists and the process running the composer client can access it, then it should work

dwakeman (Thu, 25 May 2017 20:27:51 GMT):
ok. I only have composer-cli and composer-rest-server installed. is that all I need? I just want this container to be my rest server.

dselman (Thu, 25 May 2017 20:29:24 GMT):
does the connection profile have the "networks" property, with your network listed?

dwakeman (Thu, 25 May 2017 20:29:41 GMT):
yes, and I verified that the id is correct

dselman (Thu, 25 May 2017 20:30:19 GMT):
can you try `export DEBUG=*` and then run `composer-rest-server` it might output something useful...

dwakeman (Thu, 25 May 2017 20:31:17 GMT):
the trace log shows that it is picking up the connection profile and has all the right data from it, so I know it has access to it. I guess I will keep poking around and try a few things, including the debug. Thanks!

dselman (Thu, 25 May 2017 20:31:49 GMT):
looks for certificate or auth failures when it tries to connect. these would come from the Fabric Node-SDK

dselman (Thu, 25 May 2017 20:31:59 GMT):
maybe there are some clues in there

dselman (Thu, 25 May 2017 20:32:50 GMT):
it could be some ssl library issue??

dselman (Thu, 25 May 2017 20:33:06 GMT):
You are on Ubuntu 16?

dwakeman (Thu, 25 May 2017 20:33:28 GMT):
no, 14.0.4

dselman (Thu, 25 May 2017 20:34:30 GMT):
it's all up to date?

dselman (Thu, 25 May 2017 20:34:56 GMT):
Node version good?

dwakeman (Thu, 25 May 2017 20:35:38 GMT):
hmm... I see this in the debug, so it can't generate the cert..... ``` hfc [MemberServicesImpl.enroll] failed to create cert pair: err={"code":2,"metadata":{"_internal_repr":{}}} +10s hfc [memberServices.enroll] err=Error: Identity or token does not match., enrollment=undefined +1ms strong-globalize ~~~ lang = en a2487abefef4259c2131d96cdb8543b1 ["Error: Identity or token does not match."] /usr/local/lib/node_modules/composer-rest-server/node_modules/strong-globalize/lib/globalize.js +2ms strong-globalize *** a2487abefef4259c2131d96cdb8543b1 not found for en.

dwakeman (Thu, 25 May 2017 20:36:29 GMT):
I will update everything just to be sure. thx for the help!

dselman (Thu, 25 May 2017 20:36:41 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=j9x4f55mZH9axfdAp) @nkl199 [ ](https://chat.hyperledger.org/channel/composer?msg=Lm5XfP6iNnQLAZ7qk) @dselman Following what I was doing.

dselman (Thu, 25 May 2017 20:46:37 GMT):
@dwakeman can you try copying the certificate for the admin user from your Mac box to your Linux box. Drop it into the ~/.composer-credentials dir

nehalshah50 (Thu, 25 May 2017 20:48:03 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=F8MiJHCmwom4x462F) @nehalshah50 I started by importing blank template..Added the model file then tried adding new script file...i copied code into it and tried to click deploy and the script file would disappear. Finally I got around by reusing existing template (ex. car-auction) and changing code.

dselman (Thu, 25 May 2017 20:49:01 GMT):
@dwakeman it needs to go in your keyValStore dir

dwakeman (Thu, 25 May 2017 20:53:51 GMT):
@dselman u mean the member.WebAppAdmin file in .composer-credentials?

dwakeman (Thu, 25 May 2017 20:56:58 GMT):
@dselman that gives a different error about the TCert..... `hfc Failed getting a new TCert [Error: signature does not verify] +10s`

dselman (Thu, 25 May 2017 20:57:51 GMT):
no, you were trying to connect as `admin` in the trace above

dwakeman (Thu, 25 May 2017 20:58:09 GMT):
this time I ran it with WebAppAdmin

dselman (Thu, 25 May 2017 20:58:33 GMT):
Use the same user as the one that works on the Mac, and copy that cert to Linux

dwakeman (Thu, 25 May 2017 20:58:38 GMT):
but i did see some other missing value: ``` hfc Failed getting a new TCert [Error: signature does not verify] +10s strong-globalize ~~~ lang = en a2487abefef4259c2131d96cdb8543b1 ["Error: Error: signature does not verify"] /usr/local/lib/node_modules/composer-rest-server/node_modules/strong-globalize/lib/globalize.js +4ms strong-globalize *** a2487abefef4259c2131d96cdb8543b1 not found for en. Fall back to: "Connection fails: Error: Error: signature does not verify It will be retried for the next request." *** Error: E_MISSING_MESSAGE: Missing required message content `a2487abefef4259c2131d96cdb8543b1`. +1ms Connection fails: Error: Error: signature does not verify It will be retried for the next request.```

dwakeman (Thu, 25 May 2017 20:59:06 GMT):
ah, sorry. On my mac I used WebAppAdmin. My bad. forgot that I've been switching users back and forth trying stuff.

dwakeman (Thu, 25 May 2017 20:59:55 GMT):
and that is the cert I copied to linux.

dselman (Thu, 25 May 2017 21:00:54 GMT):
So, let's recap...

dselman (Thu, 25 May 2017 21:01:04 GMT):
1. It runs fine on the Mac using WebAppAdmin

dselman (Thu, 25 May 2017 21:01:25 GMT):
2. You copy the WebAppAdmin cert to Linux, putting it in the keyValStore dir

dselman (Thu, 25 May 2017 21:01:35 GMT):
3. It fails with the error above...

dwakeman (Thu, 25 May 2017 21:01:56 GMT):
yes. I assume by cert you mean the file named member.WebAppAdmin

dselman (Thu, 25 May 2017 21:02:16 GMT):
The connection profile is identical except for the keyValStore location on both machines

dselman (Thu, 25 May 2017 21:02:21 GMT):
yes

dselman (Thu, 25 May 2017 21:02:52 GMT):
Node versions are the same

dwakeman (Thu, 25 May 2017 21:03:19 GMT):
yes to connection profile.

dwakeman (Thu, 25 May 2017 21:03:48 GMT):
no to node.... v6.10.2 on mac, v6.9.5 on linux

dwakeman (Thu, 25 May 2017 21:04:28 GMT):
could my instance be out of TCerts? ``` hfc shouldGetTCerts: yes, we have no tcerts +1ms crypto keypair: +62ms crypto ecdsa signature: Signature { r: , s: , recoveryParam: 1 } +9ms hfc Failed getting a new TCert [Error: signature does not verify] +10s```

dselman (Thu, 25 May 2017 21:05:30 GMT):
I don't think so -- it downloads them in batches, it looks like it tries to get another batch and the certs don't match

dselman (Thu, 25 May 2017 21:05:58 GMT):
can you humour me and try running in Linux, but as a non root user?

dwakeman (Thu, 25 May 2017 21:06:12 GMT):
sure

dselman (Thu, 25 May 2017 21:06:19 GMT):
I've seen npm modules that don't like running as root

dwakeman (Thu, 25 May 2017 21:07:50 GMT):
that means I have to copy .composer-connection-profiles and .composer-credentials to the new user's home directory, right?

dwakeman (Thu, 25 May 2017 21:13:17 GMT):
Got the same error. I think I am going to build a new container. I may have messed this one up with all my hacking. I'll report back tomorrow if it still doesn't work. Thx @dselman !

dselman (Thu, 25 May 2017 21:13:46 GMT):
good luck!

dwakeman (Fri, 26 May 2017 02:15:09 GMT):
@dselman Reporting back on my earlier issue with my docker container not connecting to fabric. I built a new ubuntu container and made sure to run updates and upgrades, so now it is 16.04. Still got the same error, tried a number of things. Turns out that I can't seem to use admin or WebAppAdmin, but I CAN use one of the other users! I tried it with user_type1_0 and it worked! it also seemed to create a member.user_type1_0 file for the cert in /home/composer/.composer-credentials. I tried the original attempt with WebAppAdmin and the cert present and not present and it failed, so I am still a bit stumped as to what's tripping it up, or where it's finding something it doesn't like. At the moment, though I will revel in the triumph of getting composer-rest-server running in a docker container to connect to my Bluemix instance of fabric! Thanks again for your help earlier.

torresjeff (Fri, 26 May 2017 02:19:48 GMT):
@dselman @sstone1 any news on the event hub timeout fix for hlf v0.6?

dwakeman (Fri, 26 May 2017 03:21:57 GMT):
@dselman okay, amending my last comment. I did get my container to work with an enrollID I hadn't used before, but when I deleted that container and created a new one, I got the same error when using that same enrollId. I tried a different one and it worked. I haven't figured out all the security yet, but it would appear as though composer is generating some sort of key based on the "hardware" address (or something unique to my mac or a docker container), and and then Blockchain is storing that key in the blockchain or somewhere. If it does that, and then I come along later and use the same enrollId with a different machine/container, it generates a different key. When it sends that key to Blockchain, it gets compared to the one "on file" and they don't match. I'm not sure that makes any sense but I am not copying anything but my connection profile into the container, so the mismatch must be coming from a value that gets generated in the client and a value that was previously stored in blockchain for the same user.

sstone1 (Fri, 26 May 2017 03:44:42 GMT):
@torresjeff there is nothing the composer team can do about the event hub timeout fix. at this point, the fabric team are highly unlikely to fix v0.6. i know they are looking at fixing it for v1.0 though.

torresjeff (Fri, 26 May 2017 03:57:33 GMT):
@sstone1 in theory, i shouldn't get any errors if i re-create the connection for every request right?

torresjeff (Fri, 26 May 2017 03:58:04 GMT):
even when i do that i get the `Connection reset by peer` error

torresjeff (Fri, 26 May 2017 04:26:15 GMT):
also, is it posible with the events functionality in composer 0.7.3 to know when the event hub times out?

@dselman : Where i can find evenHubURL to configure connection.json file for fabric 0.6?

@deepakvparmar connection profiles for v0.6 are described here https://hyperledger.github.io/composer/reference/connectionprofile.html eventHubURL is required and is on a port 2 above that of the peer url if you are using the v0.6 docker images

@deepakvparmar bluemix should provide the ability to show the service credentials. And how to map those details is described here https://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service for v0.6

dselman (Fri, 26 May 2017 09:14:46 GMT):
@dwakeman so my understanding of how this is *supposed* to work is as follows. You can generate a new enrollment id using Fabric APIs (we wrap these APIs for the Composer issue/revoke identity commands). Fabric creates an enrollment _secret_ for the enrollment id, which can be used *one time* to download the cert for the enrollment id from the certificate authority (it is *not* a password). Once you have the cert that is used to authenticate to Fabric and the enrollment secret is ignored. The default Docker images contain the enrollment ids and secrets for a bunch of default users. I'm using Bluemix does something different in this regard. So, I'm still surprised that you were not able to move the cert from the Mac to your Ubuntu machine and use it to authenticate.

HI there, just checking back on my ACL Questions So if I have a simple model definition which looks like this: namespace org.ibm.test participant User identified by email { o String email } asset Asset identified by assetId { o String assetId o String value } Where I have created a participant jeff@mail.com just wondering what ACL I would need to create to allow jeff@mail.com to create an asset. I thought that rule JeffCreateAsset { description: "Jeff can Create Assets" participant: "org.ibm.test.User#jeff@mail.com" operation: CREATE resource: "org.ibm.test.Asset" action: ALLOW }

[ ](https://chat.hyperledger.org/channel/composer?msg=Cz73t5Qeia92GghCL) @dselman question on your comment...and I might be confusing topics...for v1 in all the local development we do thus far have used id admin and password of adminpw...are you saying we don't really need to use adminpw after we get our certificate established? Maybe I'm missing something at a Composer level that it's needed.

My manager has asked me a question that got me thinking about Composer and 'concept' of smart contract, I'd like your feedback (anyone). With smart contract between different participants on network you operate, you can share the contract with them, and they can inspect and see what is involved to get to the result. To build a trust between you. With Composer, the Business Network becomes chaincode in itself so in real world does that mean you would share the composer cto and JS files with other participants for their inspection?

jdockter (Fri, 26 May 2017 13:17:19 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=nqE94biywjwnzHT7i) @rfu2k It's my understanding participants would in most cases have their own peer in the network, that peer would be apart of a channel, each peer in the channel would have the composer cto model and transaction logic

rfu2k (Fri, 26 May 2017 13:23:06 GMT):
@jdockter thanks for reply. The channel would have the deployed bna, and participants would have access to make calls against the transactions etc but I guess they would need access to the source code perhaps via a git repo shared with them. I'm curious how in real world it's handled, I've never deployed such an application in production and curious how the interactions between participants are handled in such a way :) btw my understanding is that rather than participants most likely having a peer, it's more the other way around, with a peer handling multiple participants. From discussion with Fabric performance testers it seems it has focused on low number of peers (4) that would serve access to the business network to many participants, perhaps over the REST API with ACL enabled.

dwakeman (Fri, 26 May 2017 13:24:50 GMT):
@dselman so I think there are really two different issues going on here. 1) when I copy a cert from my mac to ubuntu docker container, I get an error that says "signature does not verify". 2) when I don't have any certs in my .composer-credentials directory, I get an error that says "identity or token does not match", but ONLY for a user that I have previously used successfully to connect to fabric. If I use a user that has never been used, it works. I will gladly write something up on Stack Overflow so we can move the conversation there. Thanks!

dwakeman (Fri, 26 May 2017 14:54:15 GMT):
@DennisM330 your connection profile should have a section called networks. Here is mine: ``` "networks": { "pharma-network": "69ec9e74035743235f1245a75a4b7482fc4b900be369d75619b0af321d6c0b7b" }``` I'm not sure where to get the names of the samples, but the id field is the chaincode ID, which you can get from the dashboard on the network tab.

dwakeman (Fri, 26 May 2017 14:55:31 GMT):
I suspect the name can be anything you want, as long as it matches the name you specify with composer. But don't quote me on that, I haven't actually tested it. :slight_smile:

@tennenjl @DennisM330 seems to work without that file, maybe there's default behavior

rfu2k (Fri, 26 May 2017 15:46:32 GMT):
@guyho you can't add it direct from composer, there was an issue to be raised for that, just create the file in your directory

dwakeman (Fri, 26 May 2017 15:46:33 GMT):
@guyho I noticed that too. I was able to work around it by exporting my bna file, unzipping it, adding the acl flie, then using composer archive to create a new bna file that I imported back into playground.

@dwakeman, Great news on the Docker image. One issue that is documented is the component-rest-server occasionally terminates when the network connection to the peer is reset

guyho (Fri, 26 May 2017 15:50:38 GMT):
@tennenjl meaning you exported bna, unzipped, added an acl file, then reimported it?

rfu2k (Fri, 26 May 2017 15:51:34 GMT):
if you have the folder and code, there's no need to export it every time if just changing the ACL. Edit it local and archive it back up, redeploy into playground

tennenjl (Fri, 26 May 2017 15:51:48 GMT):
@guyho, no, I exported my .bna file and then imported it directly into sandbox, where it recognizes my ACL file

dwakeman (Fri, 26 May 2017 15:52:18 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=tofqt9xRfMKF9SZ5c) @jdockter Absolutely. I'm still working out some kinks, but hopefully early next week I will have a dockerfile that I can share. The big issue so far is one that I've posted above, regarding certs and the inability to "re-use" the same enrollment id from more than one machine. I have a workaround for the moment, just need to clean up and parameterize my dockerfile. Oh, and I should probably test my containers.:sunglasses:

rfu2k (Fri, 26 May 2017 15:57:39 GMT):
my question is with Composer-Rest-Server, what does enabling security actually do? I thought maybe it applies ACL but seems just to lock everything down to 401 including calls from the admin user. I'm currently looking through the Git repo to try understand it, if anyone can let me know and save me some time

rfu2k (Fri, 26 May 2017 16:29:48 GMT):
something I'm not sure about with ACL handling is that the asset is checked before the permission of the participant to carry out the act is checked. I ran a transaction operation against an asset with a participant who is denied the operation. I get the following message: Error: Object with ID 'listingId:3857' in collection with ID 'Asset:net.biz.ryanexample.JobListing' does not exist If I use an existing asset ID, I get the permission denied error message returned: Error: Participant 'net.biz.ryanexample.Company#random' does not have 'CREATE' access to resource 'net.biz.ryanexample.DoSomething#...' But if I was an attacker, I'd know that there is an asset at that listingId if I don't get the resource access error back first. I don't know in the real world how worrisome that is, seems I'd expect the access resource returned all the time for a participant who can't do the operation - no matter if the asset is there or not.

Is there a concern that if I was an attacker, I'd know that there is an asset at that listingId if I don't get the resource access error back first? I don't know in the real world how worrisome that is, seems I'd expect the access restriction returned all the time for a participant who can't do the operation - no matter if the asset is there or not.

sachikoy (Fri, 26 May 2017 16:48:53 GMT):
Hi, I have a question. Is it possible to return an event from a composer application? If not, how can we return an error when processing a transaction?

sstone1 (Fri, 26 May 2017 17:16:56 GMT):
@rfu2k I've promised multiple people over the last week that I'd get REST security documented by next week, so look out for that. basically it allows you to enable authentication of REST clients, and allows those clients to supply their own Blockchain identities.

sstone1 (Fri, 26 May 2017 17:17:45 GMT):
Also that security problem is probably a bug and we should look into it, can you raise an issue on GitHub?

sstone1 (Fri, 26 May 2017 17:22:32 GMT):
@dwakeman whats the difference between your Docker container and the hyperledger/composer-rest-server one?

sstone1 (Fri, 26 May 2017 17:23:34 GMT):
The "official" one works in both Docker and Kubernetes, you just need to know the magic env vars to configure it 😉

dwakeman (Fri, 26 May 2017 17:23:42 GMT):
@sstone1 I didn't know there already was one. I will gladly use it!

dwakeman (Fri, 26 May 2017 17:23:54 GMT):
is it in dockerhub?

sstone1 (Fri, 26 May 2017 17:24:35 GMT):
Yeah, it is published by the builds.

dwakeman (Fri, 26 May 2017 17:25:32 GMT):
Ah, yes, I see. I enjoyed the exercise of building another image, but I will most gladly use the official one. Thanks!

sstone1 (Fri, 26 May 2017 17:25:35 GMT):
Expect a doc on how to deploy a highly available REST server (or something along those lines) as well as the security stuff

dwakeman (Fri, 26 May 2017 17:26:24 GMT):
I assume there are ENV variable for the network name, enrollment id and secret, connection profile, namespaces and security

I may have asked this is the past but going to circle back around for sanity...in our model were trying to determine the pros and cons of one asset with many two concepts vs three assets that provide a relationship to each other.

jdockter (Fri, 26 May 2017 18:00:50 GMT):
With one asset I have this: pro - simplicity to add and update, either via Loopback integration or REST. Also could provide easier analytics and complex query support down the road con - only a single identified by key to lookup the asset, for now

jdockter (Fri, 26 May 2017 18:00:59 GMT):
With three assets I have this: pro - each asset is it's own registry and thus can use identified by values to quickly lookup those assets individually con - harder to maintain code to create and update linked assets over three different registries

[ ](https://chat.hyperledger.org/channel/composer?msg=nqE94biywjwnzHT7i) @rfu2k the business network definition (source) is published to the ledger. We would like to add a new `composer` cli command to download the BNA from a running Fabric. You can already do that via API.

dselman (Fri, 26 May 2017 18:02:38 GMT):
But, I agree that there is probably also a shared git repo that all the members (maintainers) of the network have access to, and this is where they review and approve changes to the models and logic.

uchi (Fri, 26 May 2017 18:04:50 GMT):
Hi, I was setting up a hlfv1 business network on Mac following this tutorial (https://github.com/hyperledger/composer/wiki/Tutorial-2) in the wiki but the tutorial does not work for hlfv1. I was able to adapt it to work for hlfv1 and I created a new wiki page in a new repo with the steps to follow to create a hlfv1 solution.

dselman (Fri, 26 May 2017 18:05:55 GMT):
@uchi 5 I'd love to see that -- I will be updating the tutorial next week and moving it into the official docs

uchi (Fri, 26 May 2017 18:08:53 GMT):
I was wondering if it's possible to update the wiki with the tutorial for setting up a hlfv1 solution. I have opened an issue< https://github.com/hyperledger/composer/issues/1101, for this. Issue goes into more details and points to the commit on my repo with the fix. This is my first attempt so contribute to any project so I apologize if I am not doing anything right. This is the tutorial (https://github.com/uchibeke/composer-wiki/blob/master/Composer-Solution-For-v1.md) I created by modifying the existing tutorial

dwakeman (Fri, 26 May 2017 19:07:07 GMT):
Okay for any interested parties who were following my earlier threads on composer-rest-server, I thought I would report back. Thanks to @sstone1 I learned that we have an official docker image for it. I pulled the image but it took a few tricks to get it to work. The server uses environment variables to find your connection profile name, network name, enrollment id and enrollment secret. I put them in a file called fabricvars.list, which looks like this: ```COMPOSER_CONNECTION_PROFILE=bmxHackathon COMPOSER_BUSINESS_NETWORK=pharma-network COMPOSER_ENROLLMENT_ID=user_type2_0 COMPOSER_ENROLLMENT_SECRET=c949379c3f``` I then ran this command to create and run my container: `docker run -p 3000:3000 --env-file ./fabricvars.list hyperledger/composer-rest-server`

dwakeman (Fri, 26 May 2017 19:09:06 GMT):
That failed, though, because my connection profile wasn't there yet. So I used docker exec to attach to the container and create the /home/composer/.composer-connection-profiles directory. Then I created the /home/composer/.composer-connection-profiles/bmxHackathon directory. I disconnected and then used docker cp to copy my connection.json to the bmxHackathon directory. Then I stopped and started the container and it worked!

dwakeman (Fri, 26 May 2017 19:10:44 GMT):
@dselman I still have the same issue with the certs, though. I've gotten this far by continuing to roll through the sample users that got enrolled with the bluemix blockchain service, but eventually I will run out of users.

dselman (Fri, 26 May 2017 19:12:38 GMT):
That is not good. It sounds like a Fabric issue to me. Did you try posting to #fabric to see whether anyone else has had issues moving certs around.

dwakeman (Fri, 26 May 2017 19:13:17 GMT):
no, but I did post the issue on stack overflow. I will post on fabric.

dselman (Fri, 26 May 2017 19:13:45 GMT):
@dwakeman we also have an option to load a connection profile from an ENV var... So you can bake it

guyho (Fri, 26 May 2017 20:23:50 GMT):
In Composer Playground... Are there any more examples than "bond-network" that show a function that creates an asset? Curious if there's advantage to having a transaction/function create an asset (like "bond-network") or just use the +Create New Asset. If no function then how would an API be exposed to create them?

sstone1 (Fri, 26 May 2017 21:22:18 GMT):
@guyho you need a transaction if you have additional business logic around just adding an asset to an asset registry. otherwise you can use the CRUD operations in the client APIs (AssetRegistry.add) or the POST /AssetType operation in the REST API

davidkel (Sat, 27 May 2017 08:12:59 GMT):
@RameshKunhiraman you can't create channels using composer. Composer is expecting an already existing channel to deploy to. Composer provide any way to create endorsement policies and so the default endorsement policy will be used.

SahilKapoor (Sat, 27 May 2017 11:21:04 GMT):
In Composer 0.7.3, events can only be subscribed via composer client but is there any address which java can use to subscribe them.

SahilKapoor (Sat, 27 May 2017 11:21:04 GMT):
In Composer 0.7.3, 1. Events can only be subscribed via composer client but is there any address which java can use to subscribe them. 2. If developing composer client app on windows, would it work i.e will it be able to connect to fabric? If so, I only need to copy profile in of the folders? 3. Getting started app is enough to get started or should we generate it via yo?

sstone1 (Sat, 27 May 2017 11:40:55 GMT):
@SahilKapoor the Composer chaincode publishes events with an event ID of `composer` - if you can figure out how to use the Fabric Java SDK to subscribe to them, give it a go. The event ID is "internal" and so subject to change in the future.

sstone1 (Sat, 27 May 2017 11:41:22 GMT):
I think Composer installs on Windows but will not deploy due to a bug in the Fabric SDK. You will need to copy in the connection profile.

sstone1 (Sat, 27 May 2017 11:43:21 GMT):
https://hyperledger.github.io/composer/unstable/integrating/enabling-rest-authentication.html for anyone that wants to find out about securing the REST APIs generated by the Composer REST server (I've forgotten who I promised this to).

davidoevans (Sat, 27 May 2017 12:35:20 GMT):
In the sample application on the playground, I can create multiple Identities against a single participantId. Can someone clarify if that is logical and if so, why?

sstone1 (Sat, 27 May 2017 12:49:51 GMT):
Yes, that is logical. As a participant, I may want several identities to use across different systems - for example my laptop, my desktop, a remote web server - and I may want to revoke/refresh those identities independently.

davidoevans (Sat, 27 May 2017 12:53:07 GMT):
so the participantId is what is recorded int the state database/blockchain...and the identity is what's used for authentication and access control?

davidoevans (Sat, 27 May 2017 12:53:40 GMT):
...and someone could have multiple points they want to authenticate from?

sstone1 (Sat, 27 May 2017 12:54:02 GMT):
the participants (and their ID) are recorded in the world state, and so is the mapping from identity (enrollment certificate in Fabric terms) to participant ID

davidoevans (Sat, 27 May 2017 12:54:27 GMT):
are those separate ledgers?

davidoevans (Sat, 27 May 2017 12:54:47 GMT):
...to keep identity separated from transactions?

davidoevans (Sat, 27 May 2017 12:55:37 GMT):
(or perhaps separate channels)

davidoevans (Sat, 27 May 2017 12:55:48 GMT):
which implies separate ledgers

sstone1 (Sat, 27 May 2017 12:55:50 GMT):
no, a single ledger in a single channel.

davidoevans (Sat, 27 May 2017 13:01:48 GMT):
at a business level - if i'm a car dealer that works at multiple dealerships, could I have a single participant id but and multiple identities I would use to authenticate on a Composer-based CarSales system?

sstone1 (Sat, 27 May 2017 13:03:14 GMT):
yes. you can either distribute a single identity across all of the dealerships, or use multiple identities mapped to the same participant ID.

davidoevans (Sat, 27 May 2017 13:05:28 GMT):
would the modelling difference be defined by associating a dealership as a property of a participant or an identity?

sstone1 (Sat, 27 May 2017 13:07:41 GMT):
identities are not modelled. the car dealer participant might have an array of relationships to dealerships that they are authorized to work at?

sstone1 (Sat, 27 May 2017 13:09:04 GMT):
identities are simply a badge/pass that lets you into the network, and each identity is mapped to a participant in the network

sstone1 (Sat, 27 May 2017 13:09:16 GMT):
the ACL rules define what a participant can do

davidoevans (Sat, 27 May 2017 13:10:19 GMT):
ah...thank you...this is very helpful

davidoevans (Sat, 27 May 2017 13:10:58 GMT):
is there a docker image of composer playground i can install locally over fabric v1.0 yet?

sstone1 (Sat, 27 May 2017 13:12:30 GMT):
you can download and run playground locally using docker: `docker run -d -p 8080:8080 hyperledger/composer-playground`

sstone1 (Sat, 27 May 2017 13:12:38 GMT):
once running, you can add a connection profile to fabric v1.0

sstone1 (Sat, 27 May 2017 13:12:56 GMT):
there is no docker compose script as fabric v1.0 is a _bit_ more complicated to set up

sstone1 (Sat, 27 May 2017 13:13:11 GMT):
but if you enjoy `curl | bash` style installers you can do it that way... hang on

sstone1 (Sat, 27 May 2017 13:13:35 GMT):
`curl -sSL http://hyperledger.github.io/composer/install-hlfv1.sh | bash`

davidoevans (Sat, 27 May 2017 13:14:22 GMT):
cool...will try that a bit later and i'm sure will be back with more questions. thanks again.

sstone1 (Sat, 27 May 2017 13:14:25 GMT):
np

davidkel (Sat, 27 May 2017 13:51:51 GMT):
@davidoevans if you plan to try to run the playground docker container against a local fabric environment it's a bit more complex to do. The curl|bash installer mentioned by simon solves that problem but does install everything. If you already have a local fabric v1-alpha you want to work with then this stackoverflow article will provide more info. https://stackoverflow.com/questions/44117260/docker-version-of-composer-playground-is-not-able-to-connect-to-local-hlf-1-0-0

davidoevans (Sat, 27 May 2017 14:14:54 GMT):
thanks @davidkel i had a local fabric installed but that was about it so i was fine to tear it down and use the all-in-one hlfv1 curl package @sstone1 provided. the install and startup worked great so will try playing with that to model a business network and interact with it. thank you both.

@sstone1 thank you for the REST API write up. Can i ask you a question about it with security arg set to false, I understand the rest server takes the identity of the user id/pass provided to it at start up. Am I correct in saying that the enrollment certificate for that user from Fabric CA is brought down into the wallet and used to sign calls into the network? (From reading the doc, I'm confused if the certfificate in the wallet mechanism was always there or is 'new' with the security arg set to true. But i guess it must always work like this, else it would be passing the user/secret every call?).

sstone1 (Sat, 27 May 2017 18:12:17 GMT):
You're correct, an enrolment certificate is always bought down from the CA to sign calls into the network. With security = false, the enrolment certificate for the ID is always used. With security = true, an enrolment certificate for the logged in user is always used.

sstone1 (Sat, 27 May 2017 18:12:59 GMT):
Perhaps I should have called the option "multiuser" rather than "security" as security = false gives the wrong impression.

@bejavu Mac is supported and you will encounter a lot of problems trying to use windows. Can you describe how you have set up your environment on mac, such as node/npm levels, docker and docker-compose versions. Also which version of hyperledger fabric are you trying with v0.6 or v1.0.0-alpha ? If you want to get started without a real fabric you can install composer-playground as follows:

[ ](https://chat.hyperledger.org/channel/composer?msg=oyTN5cff72uFrXcy6) @jdockter the format is per strategy but I think a lot of the fields are common, especially the OAuth based ones. For example, here's one for Facebook: ``` "facebook": { "provider": "facebook", "module": "passport-facebook", "clientID": "INSERT_CLIENT_ID_HERE", "clientSecret": "INSERT_CLIENT_SECRET_HERE", "authPath": "/auth/facebook", "callbackURL": "/auth/facebook/callback", "successRedirect": "/", "failureRedirect": "/" } ```

sstone1 (Sun, 28 May 2017 20:04:44 GMT):
@dstarina that error means that you're using a v0.6 connection profile with v1.0 fabric, or a v1.0 connection profile with a v0.6 fabric

dstarina (Sun, 28 May 2017 20:11:19 GMT):
@sstone1 in ~/.composer-connection-profiles/ i have two folders, defaultProfile/ and hlfv1/ - where do I tell composer which of the two to use?

sstone1 (Sun, 28 May 2017 20:11:31 GMT):
how are you doing the deploy?

sstone1 (Sun, 28 May 2017 20:11:41 GMT):
if using the composer CLI, you should add the argument `-p hlfv1`

dstarina (Sun, 28 May 2017 20:14:08 GMT):
I used the quickstart. Not sure if defaultProfile existed before or was created when I tried to connect with playground

sstone1 (Sun, 28 May 2017 20:15:28 GMT):
defaultProfile gets created by the CLI when you don't specify a `-p` option

sstone1 (Sun, 28 May 2017 20:15:38 GMT):
it's a bit weird, so we're going to remove that

davidkel (Mon, 29 May 2017 07:23:52 GMT):
@bejavu based on your excerpt for the docker setup it looks like you are trying to start a fabric v0.6 environment, so using -p hlfv1 is not going to work. Composer network list needs to get the chaincode id from the connection profile you are using to talk to digitalproperty-network business network. However if you haven't deployed digitalproperty-network using the command line then defaultProfile won't have been updated with that information and so won't be able to perform the list. If you deployed using playground you can export the connection profile and hopefully that connection profile contains the data to correlate the chaincode id with a business network. Note that this is not an issue if you use a v1.0.0-alpha fabric rather than a 0.6 one.

@bejavu there are various ways of getting setup depending on what you are trying to do. You could try the quickstart which sets up hlfv1 and does some basic validation by running a sample. https://hyperledger.github.io/composer/installing/quickstart.html Check you have the required pre-reqs

davidkel (Mon, 29 May 2017 08:10:01 GMT):
@bejavu or you could try the installer which will setup hlfv1 alpha and playground as docker containers and connect them together. curl -sSL http://hyperledger.github.io/composer/install-hlfv1.sh | bash

davidkel (Mon, 29 May 2017 08:12:36 GMT):
@Dpkkmr The log you posted doesn't provide an details of the actual error. But worth checking you have all the required pre-reqs, plus how much memory do you have ? it needs to be at least 2Gb (may be more, need to look into it further)

I enter a peer (docker exec -it peer1 bash) and run the following command taken from online documentation `peer channel create -c mynewchannel -o orderer:7050` But i get this error: `panic: Setting up the MSP manager failed, err KeyMaterial not found in SigningIdentityInfo ```

Hi I am not sure this is the right channel, I need to build an application that uses blockchain to tracke and transfer digital assets between users - so I need to be able to provide some kind og system that can fulfil that - I am thinking to encrypt the assets and provide the key to the given user - so can I use the hyperledger-ca system for that? - so I can keep private keys and so on?

davidkel (Mon, 29 May 2017 09:06:32 GMT):
@bejavu The hlfv1 fabric runtime is run through docker compose which sets up a docker network. If you then tried to use the docker image of composer-playground you need to ensure you connect it to the same network and then define an appropriate connection profile in order to work with that fabric. The script does this all for you.

davidkel (Mon, 29 May 2017 09:09:41 GMT):
@FelixNielsen sounds like composer is going to satisfy what you want to do. Have a look at our website for information and tutorials https://hyperledger.github.io/composer/

davidkel (Mon, 29 May 2017 09:12:03 GMT):
@deepakvparmar That is usually a connectivity problem. Double check your profile `defaultProfile` contains the correct grpcs:// urls

davidkel (Mon, 29 May 2017 09:16:45 GMT):
@rfu2k unfortunately creating a channel is not as simple as just issuing a single command. If that came from the hyperledger fabric documentation than it needs to be improved, but I couldn't find where you might have got this from.

@deepakvparmar handshake failure could indicate problems with the certificate and/or certificatepath entries in your profile

rfu2k (Mon, 29 May 2017 09:31:56 GMT):
@davidkel I think I got it from here, from the Fabric install and instantiate docs on Github ``` Create and join channel from the remote CLI From your second terminal, lets create a channel by the name of "myc": peer channel create -c myc -o orderer:5005 This will generate a genesis block - myc.block - and place it into the same directory from which you issued your peer channel create command. Now, from the same directory, direct both peers to join channel - myc - by passing in the genesis block - myc.block - with a peer channel join command {..snip..} ```

davidkel (Mon, 29 May 2017 09:36:55 GMT):
@rfu2k I think that is really old and I don't think it's valid for alpha1 (the level composer currently works with) or the recent alpha2 drop either.

davidkel (Mon, 29 May 2017 09:40:13 GMT):
@deepakvparmar given that you are getting different errors, your certificatePath is correct and I assume you have all the certificates in your certificate entry (there should be more than one begin certificate/end certificate combination in there). Then maybe the problem isn't your end but the bluemix end ?

Need help creating channels - latest Fabric setup docs point to alpha2 images and install documentation, which isn't compatible with Composer. Trying to look back in Git history for alpha1 instructions, if anyone can help in meantime point to what is required to create a channel with the Composer quick start alpha1 images that I have already installed and setup to work with.

davidkel (Mon, 29 May 2017 10:31:51 GMT):
@Dpkkmr That timeout message comes from the fabric runtime itself and not a composer controlled timeout. It might be worth trying 4Gb to see if it makes a difference.

davidkel (Mon, 29 May 2017 10:34:43 GMT):
@rfu2k I think you are going to have to ask on one of the other fabric channels. For example you will need a version of configtxgen that is compatible with alpha1, and I don't know if they have an pre-built ones for that version (don't know if the latest prebuilt one is compatible with alpha1). In which case you would need to get the alpha1 source and built it yourself

rfu2k (Mon, 29 May 2017 10:45:12 GMT):
@davidkel thanks David. Already tried on Fabric channel, a week or so back, and was told that I seemed to have a mismatch of images downloaded from the composer quick start link. My head is melted with the whole channel creation, I just can't get my head around it. With Fabric the instructions seem to be here's how to download a network that is scripted for setup, after that it's an unknown jungle of experimentation. I think I'll have to wait til Composer is alpha2 ready, then skip the Composer quick start and just set up a Fabric network, get e2e working, then join Composer to the existing Fabric network. Sadly that's unlikely to happen before demo'ing channel privacy tomorrow.. gahh

davidoevans (Mon, 29 May 2017 14:38:07 GMT):
I'm trying to think through how to provide secure access to participants that are integrating through various 3rd party applications. Those 3rd parties have existing applications developed in .NET and Java.

davidoevans (Mon, 29 May 2017 14:42:07 GMT):
Option 1 seems to be to expose a secured REST API as per @sstone1 's recent notes. However, I believe we'd still need to come up with a solution for those clients to receive event notifications since the composer-client.BusinessNetworkConnection.on(event) subscription capabilities are only available within the Javascript client. Correct?

sstone1 (Mon, 29 May 2017 14:42:52 GMT):
Correct, though expect webhook or websocket support to be making its way to the REST server soon ;)

davidoevans (Mon, 29 May 2017 14:43:14 GMT):
ooohhh...sexy. how soon?

sstone1 (Mon, 29 May 2017 14:44:38 GMT):
Not sure. Event support only just made its way in.

sstone1 (Mon, 29 May 2017 14:45:14 GMT):
Option 2 might be for you to write a Node.js app that listens to events and forwards them to the 3rd party applications - either using HTTP, or some kind of message queue system?

davidoevans (Mon, 29 May 2017 14:47:58 GMT):
So in Option 2, the Node.js app would use composer-client...what's the underlying protocol composer-client is using and how are those being secured?

davidoevans (Mon, 29 May 2017 14:48:44 GMT):
grpcs?

sstone1 (Mon, 29 May 2017 14:49:00 GMT):
It uses the Fabric SDK (fabric-client for v1 or hfc for v0.6), which in turn uses gRPC to communicate with the remote Fabric

sstone1 (Mon, 29 May 2017 14:49:16 GMT):
Yes - you can configure that communication to be secured with TLS, and use grpcs

bejavu (Mon, 29 May 2017 14:49:51 GMT):
@davidkel is there a way to auto increase indexes in the chaincode while creating an asset \ participant? As far as I can see its should be hard-coded since we cant import \ require anything...

@bejavu not a direct answer to your question, but I got around it by generating a uuid and using that as the assets id

sstone1 (Tue, 30 May 2017 06:19:15 GMT):
@deepakvparmar the first error is caused by one of several reasons: 1) your enroll secret does not match the one provided by the bluemix service; note that it changes every time you recreate the bluemix service. 2) you have already enrolled with that enroll secret; note that enroll secrets can only be used once on one machine. 3) you have an old certificate in your key value store directory which is from a previous instance of the bluemix service.

sstone1 (Tue, 30 May 2017 06:20:10 GMT):
the second error is a known problem caused by a fabric bug; this is the "event hub bug" and it is not going to be fixed in v0.6, and we are pushing for a fix to be made to v1.0. essentially the cloud networking layer ends up killing the idle event hub connection after a period of inactivity and the fabric SDK cannot handle this.

sstone1 (Tue, 30 May 2017 06:37:46 GMT):
@alfa from your fabric configuration or administrator. if you set it up locally following the composer getting started guide, the default on fabric v0.6 is admin / Xurw3yU9zI0l and the default on fabric v1.0 is admin / adminpw

[ ](https://chat.hyperledger.org/channel/composer?msg=DmcdZEgvLMRvfcF2r) @sstone1 k get it now. and could I update this and set my own eid & esecret.?

sstone1 (Tue, 30 May 2017 06:41:45 GMT):
composer will use whatever fabric configuration you set up, so yes - if you change the default enrollment secrets you can use it with composer. you can also issue new enrollment ids/secrets to participants you create in a composer business network.

sstone1 (Tue, 30 May 2017 06:42:37 GMT):
@SanketPanchamia composer takes care of all of that flow for you. when you submit a transaction, it sends a proposal to the peers for endorsement, then sends the endorsements to the ordering service, and then waits for the transaction to be committed before returning control to the calling application/user.

SanketPanchamia (Tue, 30 May 2017 06:44:25 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=tcFsGhjEyCCqhSxT5) @sstone1 So I assume there is a default endorsing peer that for now i cannot change. Is there capability in the composer to define endorsement policies?

sstone1 (Tue, 30 May 2017 06:44:44 GMT):
the endorsing peers and the ordering service are configured by you in the connection profile

sstone1 (Tue, 30 May 2017 06:44:59 GMT):
currently you cannot define endorsement policies, this is something we are looking into

sstone1 (Tue, 30 May 2017 06:45:08 GMT):
it will use the "default" endorsement policy

SanketPanchamia (Tue, 30 May 2017 06:45:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=kJkTAvsPutcb6wj95) @sstone1 Ok that makes sense. Thanks

SanketPanchamia (Tue, 30 May 2017 06:46:14 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=inm3S8twpHywzLokS) @sstone1 What exactly is the "default" endorsement policy? I know the transactions can be access-restricted using the ACL file.

sstone1 (Tue, 30 May 2017 06:48:44 GMT):
it's whatever fabric does by default when it is not supplied with a custom endorsement policy ;)

sstone1 (Tue, 30 May 2017 06:48:54 GMT):
i'll defer that one to @davidkel who might know the details

abcoathup (Tue, 30 May 2017 07:26:04 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Gwqipoh2Kfsqoywjy) @abcoathup Looks like it can, but in playground, need to fully qualify the participant

sstone1 (Tue, 30 May 2017 07:46:11 GMT):
@abcoathup as a property or a relationship?

sstone1 (Tue, 30 May 2017 07:46:32 GMT):
you can model a relationship to an abstract participant, e.g. `--> AbstractParticipant participant`

sstone1 (Tue, 30 May 2017 07:46:53 GMT):
but you need to supply a relationship value that points to an actual participant when submitting the transaction

davidkel (Tue, 30 May 2017 08:09:24 GMT):
fabric defines the default endorsement policy on this page http://hyperledger-fabric.readthedocs.io/en/latest/endorsement-policies.html

dselman (Tue, 30 May 2017 15:22:17 GMT):
@clueless99 there's nothing built in for that. Beware logic that is not deterministic and that may give different results on different peers. E.g. time based logic should be relative to the timestamp of the incoming transaction, not use the system clock.

clueless99 (Tue, 30 May 2017 15:25:33 GMT):
@dselman so the transaction contains a timestamp by default or I need the issuer of the transaction to give one? (in the latter case they could 'cheat' the lease by requesting it form the future)

clueless99 (Tue, 30 May 2017 15:31:26 GMT):
Hmm I may be modeling this wrong actually rather than a single item that's leased based on a time lock multiple leases related to items and datetime stamped would fix that

@dklesev have you tried to deploy basic-sample-network ? If so was there an error or timeout ?

let me see

dklesev (Tue, 30 May 2017 15:59:12 GMT):
ok, have no working solution

dklesev (Tue, 30 May 2017 16:01:04 GMT):
steps before: `curl -sSL http://hyperledger.github.io/composer/install-hlfv1.sh | bash` created asset, participant and a transaction `composer-rest-server -p hlfv1 -n basic-sample-network -i admin -s adminpw -N always`

mohamoud.egal (Tue, 30 May 2017 16:22:18 GMT):
I got a question from someone who watched a Composer demo on developerWorks that I need help answering.

mohamoud.egal (Tue, 30 May 2017 16:22:32 GMT):
"Hi Mohamoud, Thanks for the tutorial. I do understand the technical aspects of the block chain. But what I am unable to understand is that the use cases that it’s trying to solve. Lets say in the case of Bitcoin if there is a double spending attack(basically 1 person trying to spend 1 coin to two participants at the same time) block chain can prevent that. But lets say in the health care industry if you would go about using block chain? Basically my question here is if there are multiple entities involved in a transaction and would like to have an access to a data block to complete a transaction then the new entity need not build any new integration points rather just request access for the secured network (through chain code) and then based on the approving bodies can view the required data ? Will that be a valid use case for block chain?"

mohamoud.egal (Tue, 30 May 2017 16:22:49 GMT):
This is where the question & demo can be found https://developer.ibm.com/tv/blockchain-demo-hyperledger-composer/

dwakeman (Tue, 30 May 2017 16:44:02 GMT):
@mohamoud.egal I posted a comment to the question. It's awaiting moderation.

dklesev (Tue, 30 May 2017 16:51:08 GMT):
@mohamoud.egal though I don't really get your point (or what the author of the question actually needs) with blockchain you can bind the data with the time and get immutability, provenance. with the use of smart contracts you can bind actions to state conditions, f.e. "transfer asset A to party B only if party C has paid" there are multiple use-cases when you think of blockchain, especially with smart contracts. f.e. provenance, automation (with conditions), data security guarantee, identities, IoT and many more (look at the vehicle manufacturing example) especially for health industry you can design generic processes f.e. to prevent drug counterfeiting (because anything can be faked, so you have to prevent such a thing on a process/data level) data access control: with composer you can define ACLs which restrict the actions available (asset, participant, transaction related). with endorsement rules you define when a transaction got validated (by somebody). additionally you can encrypt the data (look here for ideas https://github.com/hyperledger/composer/issues/1043) but you have to do the key-exchange on application level I hope my answer is helpful

DennisM330 (Tue, 30 May 2017 17:11:14 GMT):
I placed a cloud foundry app up in Bluemix I called testComposer to use with my Blockchain in Bluemix. It is essentially the composer-rest-server. I used the API Connect toolkit to create a new loopback app, installed the composer-connector and prereqs, and changed where the connector finds the profile and credentials directories to simply look in the current Node server directory. I am using API Connect in Bluemix to invoke the appropriate operation within the testComposer CF app which is configured with a profile to invoke my Blockchain

dklesev (Tue, 30 May 2017 17:36:08 GMT):
and of course if you need trust in some business conditions

dklesev (Tue, 30 May 2017 17:36:08 GMT):
and of course if you need trust (guaranteed) in some business conditions

DennisM330 (Tue, 30 May 2017 18:37:18 GMT):
Would like the fix to the hfc (Hyperledger Fabric Client) Node.js module when it becomes available that will correctly handle the connection timeout error and reconnect as required

dselman (Tue, 30 May 2017 18:45:24 GMT):
We are tracking 3 Fabric issues related to that. They are linked from here: https://github.com/hyperledger/composer/issues/1080

dselman (Tue, 30 May 2017 18:45:50 GMT):
Please advocate for those fixes using the #fabric and #fabric-sdk-node channels

dselman (Tue, 30 May 2017 18:46:02 GMT):
2 are marked as "in progress"

dklesev (Tue, 30 May 2017 18:52:49 GMT):
solved my issue. used FQN (org.acme.biznet) instead of name (basic-sample-network)

dselman (Tue, 30 May 2017 19:04:13 GMT):
:thumbsup:

dselman (Tue, 30 May 2017 19:04:50 GMT):
When the playground deploys it hardcodes the network name to be org.acme.biznet... We need to remove that.

https://github.com/hyperledger/composer/issues/902

DennisM330 (Tue, 30 May 2017 19:11:16 GMT):
@delman - Will advocate for those fixes for sure. By having my testComposer in Bluemix I can easily integrate with other services in Bluemix like API Connect and MobileFirst

dselman (Tue, 30 May 2017 19:18:08 GMT):
Makes total sense

davidoevans (Tue, 30 May 2017 20:27:09 GMT):
how frequently is the `curl -sSL http://hyperledger.github.io/composer/install-hlfv1.sh | bash` command updated? (I just ran into the org.acme.biznet issue as well) thx

sstone1 (Tue, 30 May 2017 20:33:49 GMT):
it's updated by every release, e.g. weekly

sstone1 (Tue, 30 May 2017 20:33:55 GMT):
the org.acme.biznet issue is not fixed

sstone1 (Tue, 30 May 2017 20:33:58 GMT):
it's a big piece of work

sstone1 (Tue, 30 May 2017 20:51:28 GMT):
@here the next Composer meeting is to be held at 9am UTC (10am UK, 2:30pm IST, 5pm CST) on the 1st Jun 2017. If you have any items for the agenda - anything you'd like to discuss, or the team to talk about - then please let me know ASAP. Alternatively, if you would like to spend a couple of minutes talking about your experiences with Composer, we'd love to hear from you!

jdockter (Tue, 30 May 2017 20:56:44 GMT):
@sstone1 is there still a generator for skeletal tests? I see the command `composer generator tests` but that doesn't do anything

jdockter (Tue, 30 May 2017 20:57:18 GMT):
nm...I found the link

sstone1 (Tue, 30 May 2017 20:57:28 GMT):
I think we got rid of it because it was a bit rubbish and not all that useful

jdockter (Tue, 30 May 2017 20:57:39 GMT):
oh

jdockter (Tue, 30 May 2017 20:57:43 GMT):
what about this, https://hyperledger.github.io/composer/reference/composer.generator.tests.html

sstone1 (Tue, 30 May 2017 20:57:53 GMT):
And instead added a `yo` generator for a skeleton business network definition that includes a set of sample mocha tests and the framework to run them

sstone1 (Tue, 30 May 2017 20:58:03 GMT):
needs deleting ;)

jdockter (Tue, 30 May 2017 20:59:52 GMT):
I see this for yo ```jdockter@ubuntu:~/github/customs/network$ yo hyperledger-composer Welcome to the Hyperledger Composer Skeleton Application Generator ? Please select the type of Application: (Use arrow keys) ❯ CLI Application Angular 2 Application Skeleton Business Network ```

sstone1 (Tue, 30 May 2017 21:00:35 GMT):
bottom one

jdockter (Tue, 30 May 2017 21:03:50 GMT):
mmm, not seeing anything for tests

jdockter (Tue, 30 May 2017 21:04:56 GMT):
I can just copy from CarAuction or one of the other examples

sstone1 (Tue, 30 May 2017 21:05:36 GMT):
it should automatically generate a test folder in the new business network definition

jdockter (Tue, 30 May 2017 21:07:35 GMT):
yup test folder is there but no .js file...question on the CarAuction.js...all these run with the BrowserFS so assuming all these types of tests are in memory ...what I don't understand is the before function where all the adminConnection and businessNetworkConnection is established if I'm not connecting to a real Fabric...can those ID and secret values be anything?

jdockter (Tue, 30 May 2017 21:08:11 GMT):
for example...``` before(() => { BrowserFS.initialize(new BrowserFS.FileSystem.InMemory()); const adminConnection = new AdminConnection({ fs: bfs_fs }); return adminConnection.createProfile('defaultProfile', { type: 'embedded' }) .then(() => { return adminConnection.connect('defaultProfile', 'admin', 'Xurw3yU9zI0l'); }) .then(() => { return BusinessNetworkDefinition.fromDirectory(path.resolve(__dirname, '..')); }) .then((businessNetworkDefinition) => { return adminConnection.deploy(businessNetworkDefinition); }) .then(() => { businessNetworkConnection = new BusinessNetworkConnection({ fs: bfs_fs }); return businessNetworkConnection.connect('defaultProfile', 'carauction-network', 'admin', 'Xurw3yU9zI0l'); }); });```

sstone1 (Tue, 30 May 2017 21:10:51 GMT):
OK, that's a bug then :( what version of the generator do you have installed?

sstone1 (Tue, 30 May 2017 21:11:04 GMT):
yeah the ID/secret can be admin / anything

sstone1 (Tue, 30 May 2017 21:11:50 GMT):
perhaps you'd like a sneak peek at a new testing format coming to a Composer release near you: https://github.com/sstone1/composer-sample-networks/blob/master/packages/basic-sample-network/features/sample.feature

jdockter (Tue, 30 May 2017 21:13:29 GMT):
well..that is interesting :)

sstone1 (Tue, 30 May 2017 21:15:56 GMT):
interesting good or interesting bad? ;)

jdockter (Tue, 30 May 2017 21:16:57 GMT):
interesting good...you just whip that up on vacation or what :)

sstone1 (Tue, 30 May 2017 21:18:41 GMT):
had a lot of it kicking around in a branch for a while... needed something to do when stuck in the airport over the weekend

jdockter (Tue, 30 May 2017 21:19:02 GMT):
:joy:

jdockter (Tue, 30 May 2017 21:21:25 GMT):
is this something you have planned for a specific playback...just wondering if I need to consider this anytime soon or just stick with the examples you guys already provide with mocha?

sstone1 (Tue, 30 May 2017 21:21:41 GMT):
it should be released this friday

sstone1 (Tue, 30 May 2017 21:21:59 GMT):
as part of 0.7.4

jdockter (Tue, 30 May 2017 21:23:16 GMT):
well alright alright...so what do I need to learn on this syntax? I see in commit it says Cucumber

sstone1 (Tue, 30 May 2017 21:23:59 GMT):
out of interest, how much mocha testing have you (or anyone else - feel free to chip in) done of business networks? i always wondered if it was too cumbersome for anyone to put in the effort...

sstone1 (Tue, 30 May 2017 21:24:27 GMT):
the language is called Gherkin, you can find some information here: https://cucumber.io/docs/reference#gherkin

sstone1 (Tue, 30 May 2017 21:24:46 GMT):
the "steps" for business networks needed to be doc'ed somewhere

sstone1 (Tue, 30 May 2017 21:24:53 GMT):
i'll probably bust out a wiki page for that

jdockter (Tue, 30 May 2017 21:25:27 GMT):
I was literally just starting to create some for our current sprint...so other than that just some examples

jdockter (Tue, 30 May 2017 21:26:08 GMT):
it seemed pretty straight forward, but it's all new to me

jdockter (Tue, 30 May 2017 21:26:46 GMT):
Just want something that we can easily plug into CI process...when we get that going

jdockter (Tue, 30 May 2017 21:35:00 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=HdthoZxmCj5mJetZF) @sstone1 missed your questions...I'm at ```jdockter@ubuntu:~/github/mytest$ npm list -g generator-hyperledger-composer /home/jdockter/.nvm/versions/node/v6.9.5/lib └── generator-hyperledger-composer@0.7.3 ```

dselman (Tue, 30 May 2017 21:43:25 GMT):
@jdockter a couple of the sample networks have unit tests. The easiest option with 0.7.3 is to copy that code

jdockter (Tue, 30 May 2017 21:44:12 GMT):
@dselman yup got it, thanks

dselman (Tue, 30 May 2017 21:44:21 GMT):
The unit tests tend to run against the `embedded` runtime (i.e. the JS runtime running in Node.js) -- however you can switch to use a hlf or hlfv1 runtime by simply changing the connection profile name

dselman (Tue, 30 May 2017 21:45:02 GMT):
The also use a virtualized disk so that the connection profile that is dynamically created doesn't pollute other tests

dselman (Tue, 30 May 2017 21:45:43 GMT):
I would strongly recommend everyone to create unit tests for their business logic in TP functions.

dselman (Tue, 30 May 2017 21:46:37 GMT):
it catches myriad of issues!

jdockter (Tue, 30 May 2017 22:00:33 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=TT2EqkQ8oTFky54EY) @dselman think I had missed that in the past...so just change this one line from ` type: 'embedded'` to ` type: 'hlfv1'` ...or is there more?

dselman (Tue, 30 May 2017 22:01:39 GMT):
if you use the AdminConnection to create your profile, then it has to be a complete profile -- but if you already have a profile on disk you can skip all that... One sec.

jdockter (Tue, 30 May 2017 22:01:56 GMT):
ok

dselman (Tue, 30 May 2017 22:02:03 GMT):
e.g.

dselman (Tue, 30 May 2017 22:02:10 GMT):
``` before(() => { // BrowserFS.initialize(new BrowserFS.FileSystem.InMemory()); const adminConnection = new AdminConnection(); return adminConnection.connect('hlfv1', 'admin', 'adminpw') .then(() => { return BusinessNetworkDefinition.fromDirectory(path.resolve(__dirname, '..')); }) .then((businessNetworkDefinition) => { return adminConnection.deploy(businessNetworkDefinition); // return true; }) .then(() => { businessNetworkConnection = new BusinessNetworkConnection(); return businessNetworkConnection.connect('hlfv1', 'my-network', 'admin', 'adminpw'); }) .then(() => { businessNetworkConnection.on('event', (event) => { console.log( '****** received the event ' + JSON.stringify(businessNetworkConnection.getBusinessNetwork().getSerializer().toJSON(event))); }); }); }); ```

dselman (Tue, 30 May 2017 22:02:24 GMT):
This will connect to my local profile called `hlfv1` and run the test against that

jdockter (Tue, 30 May 2017 22:03:00 GMT):
got it, thanks!

dselman (Tue, 30 May 2017 22:04:02 GMT):
We really need a section in the docs for testing... :-/

dselman (Tue, 30 May 2017 22:04:19 GMT):
We have so much cool functionality...

dselman (Tue, 30 May 2017 22:05:25 GMT):
And don't get me started on the ability to integrate with Travis CI or Circle to automate the build, test, deploy...

dselman (Tue, 30 May 2017 22:05:33 GMT):
:-)

sstone1 (Tue, 30 May 2017 22:06:43 GMT):

@dklesev there is a block-explorer channel but it's a bit of a ghost town, it would be nice if the project was updated to run against 1.0. I'd like an easy way to look at the underlying transactions.

@rama_rahul what version of HLF V1 are you trying to work with ? could you post the output to `docker ps`

davidkel (Wed, 31 May 2017 07:29:10 GMT):
@alfa part of the npm install process is to create the connection profile which when you run npm test complains it cannot find. So it looks like npm install did not run successfully. One of the requirements is you have to run npm install in the getting-started directory. If you don't then the command will run but not do what is required.

@alfa can you run the command createProfile.sh in the scripts directory and check that the file `/home/mahendra/.composer-connection-profiles/hlfv1/connection.json` is created

alfa (Wed, 31 May 2017 07:40:10 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=C2QZSGrrY4HLQCjZQ) @davidkel yeap, after running createProfile.sh. it is created

davidkel (Wed, 31 May 2017 07:45:58 GMT):
@alfa in the package.json of getting-started is this line ``` "postinstall": "scripts/download-hyperledger.sh && scripts/createProfile.sh && npm run startHLF && npm run deployNetwork" ``` and these are the steps that npm install will follow to setup and deploy the sample network. For whatever reason this has not worked for you, you could try completing the steps manually. You will also see in the package.json file what commands npm run startHLF and npm run deployNetwork will invoke as you should see entries for `startHLF` and `deployNetwork` in the file as well.

Since Composer is still in alpha stage, what's your opinion on using it in production? And - if I wanted to go beyond a demo environment - is it possible to set up a multi-node network (meaning, multiple nodes on separate machines) with composer or should I expect problems?

davidkel (Wed, 31 May 2017 10:03:59 GMT):
@AccentSandy The first error is because you already have certificates for those users in your KeyValStore and you have either got them from a local installation of fabric or you have got them from bluemix in the past but have created a new service and this will make them invalid for your current bluemix environment. It's highly recommended that you don't share the same KeyValStore directory when communicating with different running fabrics.

@akshay111meher have the asset relate to an account `--> Account owner` then in the `onMyFooTransaction` script alter the owner and update the registry... you should be able to see this in the car auction example that's loadable in the online playground

clueless99 (Wed, 31 May 2017 11:49:58 GMT):
you can get the performer of the transaction via `getCurrentParticipan` : https://hyperledger.github.io/composer/jsdoc/module-composer-runtime.html#getCurrentParticipant__anchor ... (Which isn't covered in the examples)

sstone1 (Wed, 31 May 2017 12:19:23 GMT):
you should speak to @mbwhite as he is pulling out these fabric setup scripts into a separate repo, and we should make them compatible with both x86-64 and s390x - it would be great if you could help with that?

Fanarito (Wed, 31 May 2017 13:10:58 GMT):
@clueless99 you could use a simple hash function like this one ```function hash(str) { var hash = 0; if (str.length == 0) return hash; for (var i = 0; i < str.length; i++) { char = str.charCodeAt(i); hash = ((hash << 5) - hash) + char; hash = hash & hash; } return hash; } ``` haven't tested it but it should work

@sstone1 Dumb / newbie question warning :-) . I am using the same VirtualBox VM for my fabric build. I try to build the local version of composer on it . I got the lerna bootstrap successfully done . When I run the lerna test the tests fails with a CHROME not found . ( I am running Ubuntu Server as the OS on VirtualBox ). Is there some way that I can get around this ? like phantomjs etc.

sstone1 (Wed, 31 May 2017 13:20:47 GMT):
@hariharanatarajan are you trying to develop on composer, or just use composer? if you're trying to use composer, why don't you just install it from npm or docker?

sstone1 (Wed, 31 May 2017 13:21:28 GMT):
if you're trying to develop on composer we have some scripts in the build for installing a headless chrome i can point you at

sstone1 (Wed, 31 May 2017 13:22:11 GMT):
also FYI composer only works with fabric alpha 1 at the moment so it may not work with your local fabric build

hariharanatarajan (Wed, 31 May 2017 13:23:12 GMT):
@sstone1 potentially looking at development . I already figured that the example application failed with the local fabric build :-) . Will appreciate the pointers to the script

davidoevans (Wed, 31 May 2017 13:24:31 GMT):
When running the all-in-one hlfv1 using the curl command @sstone1 provided, if I export the hlfabric profile it provides a connection.json file. However, when I go to import an updated profile, it does not accept a .json file and says it expects either .js file type.

[ ](https://chat.hyperledger.org/channel/composer?msg=eZKcepRMvscEJs4YG) @AccentSandy I had the same problem as your error 1, and wrote stack overflow question asking about it, but I haven't seen a response. What I learned in my own testing is that I think the way the authentication works is somehow specific to the hardware address. I got this error when I tried to run composer-rest-server on a machine that was different than the one on which i used composer cli to deploy my bna file. The only solution I have found so far is to use a different enrollment ID that has never been used before on your bluemix instance of blockchain service. I am planning to do some follow up testing later today or tomorrow to see if the same issue exists in v1.0 running in docker images on my mac. I am not sure if your scenario and mine are the same, but maybe my workaround will also work for you. I ended up using enrollment id "user_type1_0", but I see that your error 2 may have come from already trying that.

In the chained `.then(...).then(...)` promises that make up the return value of a transaction function what do I need to do the stop the transaction? I've tried throwing an Error but the playground reports an unhanded rejection and peforms the transaction anyway.

@sstone1 - I just removed all my containers and ran `curl -sSL http://hyperledger.github.io/composer/install-hlfv1.sh | bash`. Everything was working great when i did this on weekend but now I'm getting error `TypeError: Invalid argument type to path.join: object` when playground starts or when I try to do anything in playground. Did something change to make that unstable or is there something left in my environment that is causing that?

davidoevans (Wed, 31 May 2017 15:03:00 GMT):
ignore my last message, i just ran `docker run -d -p 8080:8080 hyperledger/composer-playground` and it still had my previous settings which by default were trying to use the `hlfabric` profile which was not working...i was then able to switch back to `Web Browser` profile and everything working. i take it that composer-playground docker was exporting volume settings locally.

@dwakeman Unfortunately it's something that the hyperledger fabric team need to answer regarding moving the ecert to another machine. I would definitely be interested to know if you have a problem with V1 as the material is stored in what should be a far more portable format.

Still haven't managed to crack it ... Could some one point at how I rollback a transaction from within a `getAssetRegistry('foo.bar').then(function(reg) {/*check something then bail out of transaction*/ });`

Fanarito (Wed, 31 May 2017 15:40:07 GMT):
@clueless99 can you not raise an error inside of the promise, and catch it with a `.catch(dostuff(data))`?

clueless99 (Wed, 31 May 2017 15:41:46 GMT):
I've been trying that do I need to do anything in the catch to bail out of the transaction? I thought the transaction needs to raise in order to roll back (sorry my js-fu is not so strong)

clueless99 (Wed, 31 May 2017 15:41:46 GMT):
I've been trying that but do I need to do anything in the catch to bail out of the transaction? I thought the transaction needs to raise in order to roll back (sorry my js-fu is not so strong)

Fanarito (Wed, 31 May 2017 15:43:20 GMT):
in the playground, if you throw an error like this `throw new Error('error encountered');` it should stop the transaction

Fanarito (Wed, 31 May 2017 15:44:18 GMT):
it does not rollback any data that was registered previously in the transaction though

clueless99 (Wed, 31 May 2017 15:45:21 GMT):
ahhh right so a `then(/*insert foo*/).then(/*try insert bar and fail*/)` will never rollback the foo?

Fanarito (Wed, 31 May 2017 15:45:57 GMT):
nope, unless you remove it in the catch statement

clueless99 (Wed, 31 May 2017 15:46:17 GMT):
Ah ha, right so it is working, I just misunderstood rollbacks

clueless99 (Wed, 31 May 2017 15:46:29 GMT):
Thanks again @Fanarito

clueless99 (Wed, 31 May 2017 15:47:01 GMT):
Would nesting them fix my problem?

clueless99 (Wed, 31 May 2017 15:48:44 GMT):
Yup looks like it did :) ... I'm seeing an `Unhandled rejection` in the console, is that expected?

Fanarito (Wed, 31 May 2017 15:53:13 GMT):
`Unhandled rejection` just means that the promise did not handle the rejection

Fanarito (Wed, 31 May 2017 15:55:01 GMT):
javascript expects every promise to to handle rejections, i.e. for every `.then` there should be an accompanying `.catch`

clueless99 (Wed, 31 May 2017 15:57:46 GMT):
Cool, catching and logging fixed it up :)

jje (Wed, 31 May 2017 17:44:25 GMT):
I can deploy the business network with a bna file and run chaincode. If I try to update the same network with the same bna file the update keeps failing (it used to work just fine for many days). I have already restarted the peer etc to have a clean system... The error message is 'Error handling message: [e7e4c30d-9485-459a-b1b2-11a8a5c52d1d]Chaincode handler FSM cannot handle message (ERROR) with payload size (33) while in state: ready'

davidkel (Wed, 31 May 2017 18:26:24 GMT):
@hariharanatarajan my vagrant environments can be found at https://github.com/davidkel/composerVagrant for development you can chose Dev or DevXenial. DevXenial is the only one that provides windows support. They all aim to link a src directory with the host so that you can edit, use git etc on the host and run/test in the vagrant box. But because of Vagrant/VirtualBox limitations DevXenial makes the virtual box filesystem the primary and exposes it to the host except Dev which does it the other way round for the Mac (which I prefer). I've not done a great deal of testing but hopefully you won't hit too many issues

dselman (Wed, 31 May 2017 19:02:11 GMT):
@jje @davidkel could this be related to the size of the network? I know that grpc has some size restrictions for RPC payloads.

dselman (Wed, 31 May 2017 19:04:53 GMT):
@jje this issue with same error message is related to enabling security (0.6). What fabric version are you on: https://github.com/hyperledger-archives/fabric/issues/882

jje (Wed, 31 May 2017 19:12:20 GMT):
@dselman : I'm still using fabric 0.6. Regarding size, the deploy works fine, why should it then fail at update?

dselman (Wed, 31 May 2017 19:13:59 GMT):
If you can consistently reproduce it, could you please create an issue and attach the BNA?

mohamoud.egal (Wed, 31 May 2017 20:29:55 GMT):
@dwakeman @dklesev thanks to you both for your responses

davidkel (Wed, 31 May 2017 20:45:53 GMT):
@jje I wonder if there is anything in the peer or chaincode logs that could give an indication https://stackoverflow.com/questions/42695751/how-do-i-see-the-logs-for-fabric-composer provides details for 0.6. A timeout on 0.6 can be an error which can't be reported back so all that can be done is to timeout the request

jje (Wed, 31 May 2017 20:48:27 GMT):
I'm not sure. I'm currently trying to switch to v1 if it is indeed related to v06 and I need to move to v1 anyway.

davidkel (Wed, 31 May 2017 20:49:37 GMT):
@jje with v1 it should report errors back so be interested to hear how things go

@sstone1 : If you can also share document on composer language for writing model, participant and script, then it would be great, which will help us what are features are available and how we can use it.

aeisma (Thu, 01 Jun 2017 07:01:19 GMT):
I would like to be able to query the history of IoT events tracked for an asset, for large numbers of assets and events. Take for example location tracking of an asset, and query where it has been on a particular date. In the current Composer model, the next location update overwrites the previous one. Keeping the location history in an array field is not scaleable. In https://github.com/ibm-watson-iot/blockchain-samples/tree/master/contracts/platform this is done by adding the transaction timestamp to the composite key user to store the asset state. A GetStateByRange query is used to efficiently retrieve state history.

sstone1 (Thu, 01 Jun 2017 07:01:19 GMT):
that is all covered in the reference guide of the docs: https://hyperledger.github.io/composer/reference/cto_language.html

aeisma (Thu, 01 Jun 2017 07:19:47 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Tvx5phuDGba3fzv5B) @sstone1 I am aware of the ideas around a transaction historian, but I am talking about efficiently accessing the time series history of an asset. The way it is explained for the historian, it is about deltas from the perspective of the transaction, possibly limited in depth. I am referring to retrieving the full history of the state of a particular asset between two timestamps.

sstone1 (Thu, 01 Jun 2017 07:22:09 GMT):
the other option would be to model a "location event" as an asset, and use the upcoming complex query support to select all "location events" for asset X between timestamps t1 and t2

FelixNielsen (Thu, 01 Jun 2017 08:13:44 GMT):
is there any support for binary datatypes or an option to store binary data with in composer?

FelixNielsen (Thu, 01 Jun 2017 08:13:59 GMT):
like a pdf, picture etc.'

dselman (Thu, 01 Jun 2017 08:28:21 GMT):
No, not at present. I'd recommend storing these off-chain -- storing a URL to the data.

FelixNielsen (Thu, 01 Jun 2017 08:29:52 GMT):
got it :)

FelixNielsen (Thu, 01 Jun 2017 08:51:34 GMT):
@dselman how far is the analytics going - it was going to be improved quite a bit

dselman (Thu, 01 Jun 2017 08:52:45 GMT):
We can now emit business events to external systems, so you can send data from the blockchain to your analytics engines and run analytics off chain.

dselman (Thu, 01 Jun 2017 08:53:16 GMT):
This could be batch analytics using something like Hadoop or streaming analytics using Spark

FelixNielsen (Thu, 01 Jun 2017 08:53:30 GMT):
thx

dselman (Thu, 01 Jun 2017 08:54:29 GMT):
we are working on complex query support at the moment. This will allow you to run some analytical queries inside CouchDB

FelixNielsen (Thu, 01 Jun 2017 08:55:32 GMT):
@dselman can 2FA be integrated with composer authentication?

dselman (Thu, 01 Jun 2017 08:56:29 GMT):
If it is supported by passport.js (and everything is!), then yes. The user would auth against the composer-rest-server (which manages their HLF cert) and then can access the Fabric.

dselman (Thu, 01 Jun 2017 08:57:18 GMT):
@sstone1 added some great docs on how to configure composer-rest-server auth this week.

FelixNielsen (Thu, 01 Jun 2017 08:57:38 GMT):

FelixNielsen (Thu, 01 Jun 2017 08:57:51 GMT):
I will check passport.js out

aeisma (Thu, 01 Jun 2017 08:58:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=bbmtp2RZyuqMJ4hqi) @sstone1 This idea crossed my mind, you'd have to make the timestamp part of the id, I guess. However, rich query is database-native and only available if supported, right? I would prefer to have this at the model level, generically available.

@FelixNielsen yes -- the composer-rest-server uses this for auth

rfu2k (Thu, 01 Jun 2017 09:03:40 GMT):
@dselman since you mentionn the rest api, I'm curious about Composer with the introduction of organizations at the Fabric layer. Seemed one of the cool things about Composer was how you could hit a channel with participant identified via the rest server. As it's shared ledger, it didn't really matter in some cases which peer handled the request. So a small number of peers could facilitate a large number of participants. With peers now going to be dedicated to specific orgs from alpha2, I wonder if that flexibility will become lost. Curious to see where it goes.

FelixNielsen (Thu, 01 Jun 2017 09:03:41 GMT):
awsome :)

dselman (Thu, 01 Jun 2017 09:05:30 GMT):
@rfu2k our expert on Alpha2 is @davidkel -- he is working hard on the port right now. That would be a good topic for the community call next week.

Hi How can I get the history of transactions by composer

rfu2k (Thu, 01 Jun 2017 09:43:40 GMT):
@xuzhao103389 which method are you connecting to your business network? If it's over REST, there's a /system/transactions endpoint you can call to GET all transactions in the transactions registry.

xuzhao103389 (Thu, 01 Jun 2017 09:45:08 GMT):
so if I set up the rest server, then I will see the /system/transactions endpoint?

xuzhao103389 (Thu, 01 Jun 2017 09:45:17 GMT):
now I am not using rest server

xuzhao103389 (Thu, 01 Jun 2017 09:46:50 GMT):
in my user case, there is 1 asset, and multiple transaction working on this asset, can I get all the transaction history based on this asset?

rfu2k (Thu, 01 Jun 2017 09:47:22 GMT):
@xuzhao103389 sure if you'd like to use REST and you run the composer-rest-server, for quick test you can open up the created explorer link and scroll down to almost the very bottom you'll see the system endpoint. Open up and you'll see the GET call for system/transactions I'm sure there will also be similar method if you are using node API (just I haven't used it, someone else can advise on that). Also you can view the transaction registry from inside Composer Playground if you have used that.

xuzhao103389 (Thu, 01 Jun 2017 09:47:57 GMT):
thanks a million :) @rfu2k

xuzhao103389 (Thu, 01 Jun 2017 09:48:03 GMT):
I will try to find out

rfu2k (Thu, 01 Jun 2017 09:48:44 GMT):
@xuzhao103389 ah but just seen your follow up, you'll GET all transactions using this method but I don't see a way to filter by asset if that's important. You might have to first get the whole list of transactions returned, then filter yourself on your end. But if you have only 1 asset I guess they'll all be related, just by design of your application. If you had a few assets, you'd get all transactions for the few assets returned and you might need filter that. Let us know what you learn, hope it goes well and suits your needs :)

So how do you generate indexes for object in the code?

bejavu (Thu, 01 Jun 2017 11:41:53 GMT):
The problem is that I cannot get an object id for an asset \ participant in the system that I know is finalized. If I user an asset for that in the system the Index will be depend on the order of the transaction

@bejavu sorry I don't understand what you are trying to do. Perhaps a code snippet would help?

rfu2k (Thu, 01 Jun 2017 12:28:16 GMT):
@bejavu do you mean index like in a database that you'd call to get the next number to assign, maybe there is a index counter of assets, and when you create a new asset you can get the next number from the index and assign it to the asset id?

Has joined the channel.

bejavu (Thu, 01 Jun 2017 12:43:17 GMT):
@rfu2k, @dselman Yes, like a DB index for an object. If I use a special counter asset, the Order of the transactions that decided by that decided by the orderer determines the value of the id. the validatior peer can

dselman (Thu, 01 Jun 2017 12:44:24 GMT):
I think it would help everyone if you backed away from the implementation and described the problem you are trying to solve.

bejavu (Thu, 01 Jun 2017 12:49:58 GMT):
@dselman still far from the implementation, just trying to understand the system and better understand the relations between the entities. If I am an issuer of an asset, lets say USD, I want the Id of that asset. I dont want to "hard code" that asset id, I want to get some identifier from the system, like in a simple db. If I use a special object\asset for it, I will get the id only after a transaction (lets say an initial issue transaction) has been ordered, and not before.

Fanarito (Thu, 01 Jun 2017 12:51:51 GMT):
@bejavu you could use a function to generate a uuid for the asset, then you have the id of the object as soon as you generate the id

Fanarito (Thu, 01 Jun 2017 12:51:51 GMT):
@bejavu you could use a function to generate a uuid for the asset, then you have the id of the asset as soon as you generate the id

@bejavu disregard -- you could use a function to generate a uuid for the asset, then you have the id of the asset as soon as you generate the id

dselman (Thu, 01 Jun 2017 12:58:04 GMT):
@bejavu the behavior of the transaction processor functions must be deterministic across all peers -- so you cannot generate UUIDs inside your TP functions. This leaves you with 2 options. 1/ generate the assets IDs on the client, with the new asset id submitted as part of the incoming transaction. 2/ Use a counter than lives on the blockchain. 2/ is not really possible because there is no global lock / synchronization between the peers, so if you are processing 2 transactions in parallel they will likely get different values for your global counter, and one of the transactions will be rolled back due to a consensus failure.

dselman (Thu, 01 Jun 2017 12:58:55 GMT):
So, there are some additional constraints you need to be aware of compared to a traditional centralized database.

dselman (Thu, 01 Jun 2017 13:00:02 GMT):
@bejavu this might make a good Stackoverflow Q & A. Can you move it there please and tag with `hyperledger-composer` ?

[ ](https://chat.hyperledger.org/channel/composer?msg=B6xJeSYSGWDRXhdJc) @AccentSandy I'm not sure I have an opinion on whether to use 0.61 or 1.0. I see that the docker-compose file for playground does pull the 0.61 images, so that makes sense why you have them, and the documentation states that as well. If you want to use the v1.0 alpha you can follow the quickstart instructions: https://hyperledger.github.io/composer/installing/quickstart.html That's how I got v1.0 to run locally. Composer playground works with both. In the quickstart instructions there are two different links to the gitub repository for the samples application, one for v0.61 and another for v1.0. I will let others comment on whether you should use one version of the other.

AccentSandy (Thu, 01 Jun 2017 13:20:49 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=gD2EKdpNFfnsu5h8K) @dwakeman Thanks. That's the link i am following now. I have got rid of all old fabric images and currently in the process of pulling the 1.0 alpha image. Hope this fixes the deployment issue that we were facing earlier. Thanks for your help.

@dselman hi, I am trying the composer-rest-server and I am not sure exactly how is the "find" with filter operation supposed to work.

uber.twin (Thu, 01 Jun 2017 13:40:48 GMT):
For instance when I try a filter similar to {"status":"complete"}, I get all instances, regardless of the value of their "status" field. It's like no filter is specified at all.

uber.twin (Thu, 01 Jun 2017 13:41:55 GMT):
the generated URL looks like this: http://localhost:3000/api/my.Participant?filter=%7B%22status%22%3A%22complete%22%7D

uber.twin (Thu, 01 Jun 2017 13:43:48 GMT):
it invariably returns all my.Participant instances, no matter what's the value of the "status" field

@nehalshah50 do you get the same problem if you connect to your local playground in an incognito window ?

nehalshah50 (Thu, 01 Jun 2017 18:42:09 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=zquDqefs8TbkhXxkw) @davidkel First time I installed it all worked fine then I tried adding new connection profile through UI and used /Users/[userid]/.composer-credentials for the keyvalueStore and it didn't like it. After that it would never start up again. So I uninstalled using 'npm uninstall' and reinstalled the local playground again. And since then it doesn't want to work

davidkel (Thu, 01 Jun 2017 18:43:31 GMT):
@nehalshah50 One of the problems is that a lot of information is stored in the browser's local storage. If you run it in an incognito window then that session will not have any old playground local storage that could cause problems

why wouldn't you be using `composer network archive` from the source?

@nehalshah50 yes, once you have connected to the fabric connection profile, the business network will get deployed to that local fabric.

nehalshah50 (Thu, 01 Jun 2017 19:23:43 GMT):
Can one fabric instance run multiple network?

sstone1 (Thu, 01 Jun 2017 19:24:52 GMT):
you can deploy multiple Composer business networks to a single Fabric instance

sstone1 (Thu, 01 Jun 2017 19:24:57 GMT):
but you have to use the Composer CLI for this

sstone1 (Thu, 01 Jun 2017 19:25:12 GMT):
Playground only supports one business network per Fabric connection profile, and it must be called org.acme.biznet

sstone1 (Thu, 01 Jun 2017 19:25:20 GMT):

nehalshah50 (Thu, 01 Jun 2017 19:58:18 GMT):
Few days back when I was playing in the online playground I found an issue. If the data model has a enum type defined in one of the data object it fails to check against enumerated values while values are being set through transactions or other means. It allows to set any values outside of available enum values. For example if Asset has one of the attribute of type enum and once the bad values is set then playground doesn't allow to go back to the asset in UI. Let me know if you need more info

davidkel (Fri, 02 Jun 2017 12:17:36 GMT):
@rama_rahul that looks like a docker registry problem to me, maybe you can't contact the docker hub services for some reason.

davidkel (Fri, 02 Jun 2017 12:18:45 GMT):
@hariharanatarajan Sorry, I don't understand the question, could you provide more details of what you are trying to do and what error you might be getting

rama_rahul (Fri, 02 Jun 2017 12:18:45 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=3DKAYncbpdTdk9qrq) @davidkel I tried to run the command again then it started without any error. Still don't understand why.

davidkel (Fri, 02 Jun 2017 12:19:15 GMT):
@rama_rahul either a problem with the docker registry service is a network problem

davidkel (Fri, 02 Jun 2017 12:19:15 GMT):

rama_rahul (Fri, 02 Jun 2017 12:19:57 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=BsKwdbdGDMKoQ86H7) @davidkel Anyway its working fine now. No issues :)

Fanarito (Fri, 02 Jun 2017 12:26:49 GMT):
using the composer-rest-server I am able to create and update assets that have invalid foreign keys, is this by design? and also, the PUT/POST/DELETE request are not recorded as transactions is that also by design?

Fanarito (Fri, 02 Jun 2017 12:26:49 GMT):

JennFoley (Fri, 02 Jun 2017 12:52:00 GMT):
I have an asset that has a relationship to a participant. In the transaction logic how do I find all assets related to the participant? There doesn't seem to be any API to resolve relationships and I'm on the many end of a 1:many relationship so the relationship isn't declared on the participant. E.g. How do I find all cars owned by a person if I currently have an instance of the person and the cars' asset registry?

Fanarito (Fri, 02 Jun 2017 12:56:30 GMT):
@JennFoley I don't think it has been implemented yet since querying is not implemented yet. The samples use an array of relationships on the 1 end, to facilitate this

dklesev (Fri, 02 Jun 2017 12:57:57 GMT):
@JennFoley I have a similar problem, but we have to wait until querying is implemented

JennFoley (Fri, 02 Jun 2017 12:58:47 GMT):
@dklesev @Fanarito that was a bit of my fear.

Fanarito (Fri, 02 Jun 2017 12:59:38 GMT):
but I think I read somewhere that querying might sneak in next week.

JennFoley (Fri, 02 Jun 2017 13:02:09 GMT):
@Fanarito I remember seeing something like that from @sstone1 . . . . too bad I need something today. Will modify my code and then reevaluate when the query is in there and see how different the impact would be

dklesev (Fri, 02 Jun 2017 13:04:34 GMT):
@JennFoley you can query on peer level I guess, so our problem is related to composer

dklesev (Fri, 02 Jun 2017 13:04:49 GMT):
https://hyperledger-fabric.readthedocs.io/en/latest/getting_started.html#using-couchdb

dklesev (Fri, 02 Jun 2017 13:04:53 GMT):
maybe it helps

dklesev (Fri, 02 Jun 2017 13:05:48 GMT):
there are even JS queries defined in the animaltracking demo for composer

dklesev (Fri, 02 Jun 2017 13:05:48 GMT):
https://github.com/hyperledger/composer-sample-networks/blob/master/packages/animaltracking-network/lib/mozart.cto.js

dklesev (Fri, 02 Jun 2017 13:10:03 GMT):
if you find out how one can use the animaltracking queries, let me know :D

davidkel (Fri, 02 Jun 2017 13:17:06 GMT):
@dklesev @JennFoley Complex query support in composer will require couchdb to be enabled in the fabric you are running. It won't be able to work with leveldb which is the default if couchdb is not enabled. Our current local dev fabric environment doesn't have couchdb enabled, it would be updated when complex query support is released

dklesev (Fri, 02 Jun 2017 13:19:38 GMT):
@davidkel but one can use complex queries without composer but with couchDB enabled? I mean the cli and peer directly

davidkel (Fri, 02 Jun 2017 13:21:24 GMT):
@dklesev Not tried that with the alpha1 images so don't know if it works

davidkel (Fri, 02 Jun 2017 13:38:14 GMT):
@JennFoley Sorry, no. Some attempts were made to use the cli on alpha1 but not much progress was made, so effort was switched to doing it through the fabric shim and then get it exposed in composer

@akshay111meher from the logs it looks like you fabric has been restarted from scratch and as such is a clean fabric with no business networks deployed

clueless99 (Fri, 02 Jun 2017 13:42:31 GMT):
@akshay111meher (I'm well out of my depth answering this ... I'm a total newbie) but are you on the latest version? This Jira ticket re: a similar problem was closed due to only impacting v 0.6 https://jira.hyperledger.org/browse/FAB-710

davidkel (Fri, 02 Jun 2017 13:45:57 GMT):
@Fanarito It looks like there is no validation to check relationships during those operations, it might be a performance tradeoff reason. CRUD operations for assets/participants are a different concept to transactions from a composer point of view so are not kept in the transaction registry. There are of course still stored on the blockchain.

Fanarito (Fri, 02 Jun 2017 13:47:19 GMT):
@davidkel but will the CRUD operation history be accessible in the same way transactions are when the historian comes out?

akshay111meher (Fri, 02 Jun 2017 13:47:30 GMT):

@akshay111meher Can you provide details of the steps you have done and error messages you get back as the log of the peer only shows it starting up and performing some sort of action and digitalproperty-network not being installed. Also it might be worth seeing what the logs in the chaincode containers say. Those are the ones starting `dev-`

@hariharanatarajan Not sure what screen you are looking at. I assume you have created a v1 profile and pressed use profile and have been presented with the above ? Also connecting docker playground to a local fabric also running in docker is not straight forward as they will be network isolated from each other.

I checked the logic.js file and content is same as given in the instructions.

Fanarito (Fri, 02 Jun 2017 15:15:43 GMT):
@nehalshah50 you are missing the license header in some file. You can either add the license header to the file or remove the license check in `package.json`

nehalshah50 (Fri, 02 Jun 2017 15:17:47 GMT):
I checked the file it complains and it has the license header stuff in it. But not sure why it fails

nehalshah50 (Fri, 02 Jun 2017 15:19:53 GMT):
I am following this guide https://hyperledger.github.io/composer/tutorials/developer-guide.html

davidkel (Fri, 02 Jun 2017 15:22:20 GMT):
@nehalshah50 The problem is the licence checker is pedantic about spacing (don't get me started on indentation rules :-) ) personally I would just disable license checking is it has no use in helping you getting started. To do that you need to change package.json In the scripts section there is a line `"licchk": "license-check",` and change it to `"licchk": "echo license-check",` (ie insert the word echo)

@hariharanatarajan It will be whatever has been defined in the ca you have configured. I don't know what that would be as it is however you set it up

nehalshah50 (Fri, 02 Jun 2017 15:26:13 GMT):
Sure. I will. I commented the lincense-check. Now the next error on 'npm test' is following : Commodity Trading 1) "before all" hook 0 passing (2s) 1 failing 1) Commodity Trading "before all" hook: Error: Timeout of 2000ms exceeded.

After disabling the license check It worked fine. Thanks

does someone else get problems with the setup-script? install-hlfv1.sh

Fanarito (Fri, 02 Jun 2017 15:39:57 GMT):
@dklesev They updated the install scripts, https://hyperledger.github.io/composer/getting-started/development-tools.html here is the tutorial for the new ones

dklesev (Fri, 02 Jun 2017 15:48:41 GMT):
sure, but the one-line install should work without problems

Fanarito (Fri, 02 Jun 2017 15:54:19 GMT):
oh right for the composer playground

[ ](https://chat.hyperledger.org/channel/composer?msg=sGYpAqQ4igfoCW89D) @davidkel .the error may be due to event hub getting disconnected from fabric.. I understood that... Issue which I am also getting is that... When a transaction is being acted upon , it is not updating the asset... I tried doing assetRegistry.update(resource) , it is still not updating the resource....

jdockter (Fri, 02 Jun 2017 17:15:09 GMT):
@sstone1 in the vehicle lifecycle network you have a setup.js which loads a number of assets and participants...is there a way to just read in a json structure without having to dummy up the json in the .js? I've seen it done on unit tests but is it possible in the lib js files?

jdockter (Fri, 02 Jun 2017 17:17:28 GMT):
the asset I have is made up of many concepts so it would seem like I would need to factory.newConcept() those parts of the asset, but maybe there is a way around that

sstone1 (Fri, 02 Jun 2017 17:58:29 GMT):
@jdockter only if you embed the JSON into the .js file

sstone1 (Fri, 02 Jun 2017 17:58:40 GMT):
there's currently no way to reference another file, .js or .json

sstone1 (Fri, 02 Jun 2017 17:59:44 GMT):
[ ](https://chat.hyperledger.org/channel/composer-dev?msg=3pPYoq8r4368q4Hno) @theophoric what OS, versions of node/npm are you using? what errors do you get?

jdockter (Fri, 02 Jun 2017 17:59:46 GMT):
@sstone1 okay figured you probably would have done it if it was possible, thanks

davidoevans (Fri, 02 Jun 2017 18:26:10 GMT):
if i have 2 different orgs defined in my Fabric Network, does it make sense that they each have a CA associated with them and only an authorized user from each org would be able to issue identities within their respective organization? if so, how would you configure that in network profile for Composer?

davidkel (Fri, 02 Jun 2017 18:57:40 GMT):
@davidoevans So I could imagine a situation where 2 organisations participating in a business network would have their own ca and I woudn't think that they would want or in fact be allowed to access the other organisations ca. So a participant in a business network would only need to declare their own ca for identities.

davidoevans (Fri, 02 Jun 2017 19:03:09 GMT):
thanks @davidkel - so what would need to be configured in Composer's connection profile to such a fabric network to support that? I ask because the sample connection that comes with Composer looks flat: ``` "mspID": "Org1MSP", "ca": "http://ca0:7054", ```

davidkel (Fri, 02 Jun 2017 19:12:52 GMT):
@davidoevans The connection profile defines the servers you want to connect to. You would include all the peers in the fabric that you need to interact with, the orderer(s) used in the fabric and then the ca relevant to your single organisation, along with your organisations MSP id.

sstone1 (Fri, 02 Jun 2017 19:13:17 GMT):
totally unsurprised about the node 8 support problems... we rely on a bunch of native modules that will need upgrading for the latest native APIs... thanks for reporting though!

I have a stupid question. What's my Fabric Username? Trying to make a rest api.

sstone1 (Fri, 02 Jun 2017 19:27:47 GMT):
it's your enrollment ID + secret

sstone1 (Fri, 02 Jun 2017 19:27:58 GMT):
so admin / adminpw on HLFv1

sstone1 (Fri, 02 Jun 2017 19:28:12 GMT):
or admin / Xurw3yU9zI0l on HLFv0.6

mattalhonte (Fri, 02 Jun 2017 19:28:25 GMT):
so literally "admin / adminpw"?

sstone1 (Fri, 02 Jun 2017 19:28:37 GMT):
no, the ID is admin, the secret (the next question) is adminpw

mattalhonte (Fri, 02 Jun 2017 19:28:45 GMT):
aha, thanks!

What should the Business Network Identifier be? My .bna file didn't work.

sstone1 (Fri, 02 Jun 2017 19:39:16 GMT):
how did you set up composer?

have you seen this tutorial btw? https://hyperledger.github.io/composer/tutorials/developer-guide.html

mattalhonte (Fri, 02 Jun 2017 19:39:58 GMT):
the composer.sh script

mattalhonte (Fri, 02 Jun 2017 19:43:10 GMT):
it says "Discovering types from business network definition ... Connection fails: Error: failed to obtain cds for

sstone1 (Fri, 02 Jun 2017 19:46:24 GMT):
org.acme.biznet is the business network definition name when installing usijng the composer.sh script

mattalhonte (Fri, 02 Jun 2017 19:46:56 GMT):
Even if that's not the .bna file that was used?

mattalhonte (Fri, 02 Jun 2017 19:47:28 GMT):
oh, ha, guess so!

dklesev (Fri, 02 Jun 2017 19:49:50 GMT):
@davidkel I'm on a linux machine. After getting updated script version with curl I see this: https://chat.hyperledger.org/channel/composer?msg=6Znn25BhpnhxwyQrr

dklesev (Fri, 02 Jun 2017 19:50:10 GMT):

nehalshah50 (Fri, 02 Jun 2017 20:25:07 GMT):
After deploying network I see always two docker containers created dev-peer0-my-network-0.7.4 and dev-peer1-my-network-0.7.4. Just for curiosity...why there are only two and what do they do? run the chain code?

mattalhonte (Fri, 02 Jun 2017 20:25:11 GMT):
Is there a way to query the REST API from the command line? I'm working with a remote machine and I can't use the browser interface

sstone1 (Fri, 02 Jun 2017 20:28:36 GMT):
`curl http://remoteip:3000/api/system/ping`

sstone1 (Fri, 02 Jun 2017 20:28:49 GMT):
but if you can do that you can point your browser to `http://remoteip:3000/explorer/` ;)

sstone1 (Fri, 02 Jun 2017 20:29:08 GMT):
oh - unless you mean `curl` on the remote machine

sstone1 (Fri, 02 Jun 2017 20:29:18 GMT):
in which case just use `localhost` in place of remoteip

sstone1 (Fri, 02 Jun 2017 20:29:38 GMT):
@nehalshah50 each peer gets its own copy of the chaincode

nehalshah50 (Fri, 02 Jun 2017 20:30:57 GMT):
each peer container corresponds to each participant in network?

nehalshah50 (Fri, 02 Jun 2017 20:32:59 GMT):
or every participant when they deploy the network on their side they will have two peer container ?

nehalshah50 (Fri, 02 Jun 2017 20:35:38 GMT):
then there are two peer containers for fabric as well....I am just trying to understand how this is all fitting together

nehalshah50 (Fri, 02 Jun 2017 20:36:12 GMT):
if there is a good arch document you can point to regarding this then that would be great

dklesev (Fri, 02 Jun 2017 20:37:48 GMT):
@nehalshah50 https://hyperledger-fabric.readthedocs.io/en/latest/

mattalhonte (Fri, 02 Jun 2017 20:38:12 GMT):
Hrm, interestingly, http://remoteip:8080/editor works, but http://remoteip:3000/explorer/` doesn't.

sstone1 (Fri, 02 Jun 2017 20:39:39 GMT):
@nehalshah50 it is important to differentiate between the participants or users of a business network (people who are authorized to submit transactions) vs the members who are running peer nodes and managing the underlying fabric network

sstone1 (Fri, 02 Jun 2017 20:39:55 GMT):
in some cases participants in the business network are members who run peer nodes, but not all of them do

nehalshah50 (Fri, 02 Jun 2017 20:43:18 GMT):
So in sample apps when we submit transaction from playground or through other means the transaction goes to both dev-peer nodes first...gets validated there and then gets sent to fabric peer nodes?

davidkel (Fri, 02 Jun 2017 20:44:20 GMT):
@dklesev I can't recreate the problems that you are getting with the latest installer, I have tried on a clean linux vagrant box. Is there any more details you can provide ? do you think there might be a port clash or a linux level issue ?

dklesev (Fri, 02 Jun 2017 20:45:24 GMT):
@davidkel hmm, don't know maybe I find the time to inspect it later on, will write you if I find the problem

davidkel (Sat, 03 Jun 2017 07:34:05 GMT):
@dklesev that's good to know, what version were you on before ? We have just updated our dependencies to docker 17.03 but it wasn't done because of a specific known issue.

dklesev (Sat, 03 Jun 2017 12:36:55 GMT):
@davidkel sorry, can't say anymore, but it met last requirements before update

I thought that only one chaincode per channel is deployable? I deployed a BNA with composer over cli and then composer-playground seems to deploy the hardcoded `org.acme.biznet` cc so I get two different cc containers: ``` 95fc0d7d4cf5 dev-peer0-org.acme.biznet-0.7.3 "chaincode -peer.a..." 13 hours ago Up 13 hours dev-peer0-org.acme.biznet-0.7.3 1d10b8bbf697 dev-peer1-org.acme.biznet-0.7.3 "chaincode -peer.a..." 13 hours ago Up 13 hours dev-peer1-org.acme.biznet-0.7.3 b9349e104430 dev-peer1-chemical-barrels-0.7.3 "chaincode -peer.a..." 13 hours ago Up 13 hours dev-peer1-chemical-barrels-0.7.3 fda8c1bdf162 dev-peer0-chemical-barrels-0.7.3 "chaincode -peer.a..." 13 hours ago Up 13 hours dev-peer0-chemical-barrels-0.7.3 ```

MeenakshiSingh (Sun, 04 Jun 2017 14:18:55 GMT):
how does composer take care of endorsements and private channels?

davidkel (Sun, 04 Jun 2017 18:11:02 GMT):
@MeenakshiSingh Composer deploys business networks to an already defined Fabric channel. It doesn't define an instantiation or endorsement policy, meaning that the fabric's default policies are used.

torresjeff (Sun, 04 Jun 2017 18:29:50 GMT):
@davidkel hey, i just got access to the bluemix limited beta for hlf v1.0, and I was wondering is there a tutorial on how to setup a composer connection profile for hlf v1.0 on bluemix?

torresjeff (Sun, 04 Jun 2017 18:42:41 GMT):
i have doubts regarding the `MSP ID`, on my service credentials i see there are multiples MSPs, including MSPs for orderers, ca, and peers

torresjeff (Sun, 04 Jun 2017 18:42:44 GMT):
which one should i use?

torresjeff (Sun, 04 Jun 2017 18:46:09 GMT):
I also see a `Hostname` text field when trying to add a certificate, what should i put on it?

davidkel (Sun, 04 Jun 2017 19:13:22 GMT):
@torresjeff There isn't one as far as I know, sorry. hostname isn't something I would expect anyone outside to development to use. It allows you to override the expected hostname in the cert. Think I will raise an issue to hide that field as it really is an advanced option. When you choose an MSP Id, you need to chose one that matches the ca you are going to use. If you imagine you are part of an organisation that has a ca and a peer in your organisation then they would have the same mspid and so that would be the mspid you want want in your connection profile.

torresjeff (Sun, 04 Jun 2017 19:17:10 GMT):
@davidkel thanks!

davidkel (Sun, 04 Jun 2017 19:24:01 GMT):
@torresjeff so specifically don't use the orderer msp :-)

torresjeff (Sun, 04 Jun 2017 19:24:10 GMT):
yup, got it

torresjeff (Sun, 04 Jun 2017 19:24:19 GMT):
thank you very much!

davidkel (Sun, 04 Jun 2017 19:25:02 GMT):
yw

torresjeff (Sun, 04 Jun 2017 19:26:02 GMT):
@davidkel btw, what is the job of the orderer?

torresjeff (Sun, 04 Jun 2017 19:26:14 GMT):
it didn't exist in hlfv0.6 right?

davidkel (Sun, 04 Jun 2017 19:30:02 GMT):
The v1.0 architecture is very different to v0.6. The Hyperledger docs should provide details on the new architecture

torresjeff (Sun, 04 Jun 2017 19:39:41 GMT):
@davidkel trying to connect to my blockchain service on bluemix but i get this error: `Error: Private key missing from key store. Can not establish the signing identity for user WebAppAdmin`

davidkel (Sun, 04 Jun 2017 19:41:30 GMT):
You need to chose an enrollementid made available from the ca you are going to use.

torresjeff (Sun, 04 Jun 2017 19:41:47 GMT):
hmm i did

davidkel (Sun, 04 Jun 2017 19:42:26 GMT):
I haven't heard of WebAppAdmin being an enrollmentid that was available from the bluemix ca's

torresjeff (Sun, 04 Jun 2017 19:42:50 GMT):
tried with admin too

torresjeff (Sun, 04 Jun 2017 19:42:53 GMT):
but get the same error

torresjeff (Sun, 04 Jun 2017 19:45:48 GMT):
@davidkel i can choose any orderer right?

torresjeff (Sun, 04 Jun 2017 19:48:48 GMT):
hmm i cant event connecto my hlf v1 fabric running locally

torresjeff (Sun, 04 Jun 2017 19:49:27 GMT):
when i try to connect from the playground i get `Error: EACCES`

davidkel (Sun, 04 Jun 2017 19:49:52 GMT):
Most likely you keyValStore is not valid

torresjeff (Sun, 04 Jun 2017 19:51:16 GMT):
oh, by default it just puts the path to the container keyValStore

davidkel (Sun, 04 Jun 2017 19:55:51 GMT):
keyValStore must be a valid path and it must be .hfc-key-store, so if you are running playground as a docker container it has to be /home/composer/.hfc-key-store. If you are running it locally and not as a container it has to be /.hfc-key-store

torresjeff (Sun, 04 Jun 2017 19:57:31 GMT):
@davidkel so is it no longer `.composer-credentials`?

torresjeff (Sun, 04 Jun 2017 19:57:42 GMT):
does the path matter?

davidkel (Sun, 04 Jun 2017 19:58:37 GMT):
Yes it does. it must be as described, sorry it was a limitation of the alpha1 fabric

torresjeff (Sun, 04 Jun 2017 19:59:48 GMT):
@davidkel does it have to be in the root of `.hfc-key-store`?

torresjeff (Sun, 04 Jun 2017 20:00:00 GMT):
or can i specify a directory inside `.hfc-key-store`

davidkel (Sun, 04 Jun 2017 20:00:23 GMT):
nope, it has to be .hfc-key-store, not a subdirectory

torresjeff (Sun, 04 Jun 2017 20:00:38 GMT):
what happens if i have multiple profiles?

torresjeff (Sun, 04 Jun 2017 20:01:03 GMT):
wouldnt it override my credentials?

davidkel (Sun, 04 Jun 2017 20:01:20 GMT):
If the same name then yes it will

torresjeff (Sun, 04 Jun 2017 20:01:48 GMT):
i mean the user

torresjeff (Sun, 04 Jun 2017 20:01:59 GMT):
it creates a file for each enrollmentId correct?

torresjeff (Sun, 04 Jun 2017 20:02:12 GMT):
eg: i have an admin id in hlfv1 running on my docker container

torresjeff (Sun, 04 Jun 2017 20:02:18 GMT):
but also have an admin id in bluemix

davidkel (Sun, 04 Jun 2017 20:02:53 GMT):
Yes, plus a private and public key file as well

torresjeff (Sun, 04 Jun 2017 20:03:42 GMT):
what would i do if i want to have both at the same time?

davidkel (Sun, 04 Jun 2017 20:04:55 GMT):
run 2 containers and publish on different ports ?

torresjeff (Sun, 04 Jun 2017 20:09:34 GMT):
the thing is im running composer-playground on top of my os (downloaded it through npm)

torresjeff (Sun, 04 Jun 2017 20:09:43 GMT):
im not running the playground on containers

davidkel (Sun, 04 Jun 2017 20:14:49 GMT):
ah, ok. Unfortunately there isn't anything I can suggest at this time. Actually thinking about it as well if you did follow the container way of 2 containers publishing to different ports you would probably have to run 2 different browsers or the same browser but one of them in incognito mode.

torresjeff (Sun, 04 Jun 2017 20:15:50 GMT):
oh ok

torresjeff (Sun, 04 Jun 2017 20:15:53 GMT):
thanks!

torresjeff (Sun, 04 Jun 2017 20:16:29 GMT):
has the composer team considered a fix for this?

davidkel (Sun, 04 Jun 2017 20:19:07 GMT):
Not something we can fix. It's an issue with the fabric node sdk itself.

torresjeff (Sun, 04 Jun 2017 21:16:30 GMT):
has anytone gotten this error `Failed to connect: Error: Failed to deserialize creator identity, err MSP Org1MSP is unknown`?

davidkel (Sun, 04 Jun 2017 21:30:43 GMT):
@torresjeff What is the MSP or the ca/peer's you are using. The connection profile needs to match those

davidkel (Sun, 04 Jun 2017 21:30:43 GMT):
@torresjeff What is the MSP of the ca/peer's you are using. The connection profile needs to match those

torresjeff (Sun, 04 Jun 2017 21:31:06 GMT):

torresjeff (Sun, 04 Jun 2017 21:31:22 GMT):
the one that uses fabric v1 running on docker

davidkel (Sun, 04 Jun 2017 21:33:54 GMT):
The MSP id that the connection profile defaults to is going to match the config used by a development fabric setup and isn't likely to match a service providers. What MSP id is given for the peers in bluemix ?

deepakvparmar (Mon, 05 Jun 2017 11:27:17 GMT):
Is my understanding correct? - We can use "composer-client" and "composer-admin" , which are internally using JavaScript SDK to communicate fabric network - If we are developing our own web application using "composer-client" and "composer-admin", then we dont need to use/initialize composer-rest-server??

@rama_rahul The license check feature is pedantic, unfortunately the docs of the code I think you have cut and paste from were missing a single space in the license block comment. The updated version can be found at https://hyperledger.github.io/composer/unstable/tutorials/developer-guide.html or as license check isn't going to be important to you for getting started, you can easily disable it. In the package.json file find the scripts section and In the scripts section there is a line `"licchk": "license-check",` and change it to `"licchk": "echo license-check",` (ie insert the word echo)

@sstone1 @davidkel @dselman , If I'm leaving up Composer Playground and Composer Rest Server for a long time -- days or weeks -- without traffic for others to develop with then do I need to do something to help keep it up?

caroline-church (Mon, 05 Jun 2017 15:28:52 GMT):
ok so this means that you can't communicate with the peer, it might be worth trying bringing the image down and up again. We've seen problems before if the machine suspends and the docker image doesn't come back up properly

@dselman @davidkel : Do we need composer-rest-server if we are developing web application using 'composer-client' and 'composer-admin'? I would like to understand what is best way of designing application , whether to use composer-rest-server or developing web application using 'composer-client' and 'composer-admin'.

davidkel (Mon, 05 Jun 2017 16:46:43 GMT):
@deepakvparmar You can develop client applications using those libraries, they don't depend on composer-rest-server

deepakvparmar (Mon, 05 Jun 2017 16:50:12 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=ZnytahT84rDdHqjgw) @davidkel : Thank you david. so , composer-rest-server is utility module to test network quickly? How if we develop application which will directly interact composer-rest-server only? What's your opinion about which way is more preferable?

theophoric (Mon, 05 Jun 2017 16:55:45 GMT):
One difference seems to be that the interface exposed by composer-rest-server for e.g. "get collection" includes a `filter` parameter which is missing from `client.getAll()`

sstone1 (Mon, 05 Jun 2017 17:21:07 GMT):
@theophoric you will find that the `filter` parameter is not that useful at the moment, because we are currently working on adding complex query support - once that is introduced, both the client APIs and the REST APIs will be extended with methods for invoking complex queries (using CouchDB)

sstone1 (Mon, 05 Jun 2017 17:22:04 GMT):
@deepakvparmar it is not a utility module, the REST server is designed for production usage. use `composer-rest-server` if you want a REST API, and use `composer-client` if you want a Node.js API - easy ;)

davidoevans (Mon, 05 Jun 2017 17:37:35 GMT):
I just started the default fabric using `./network_setup.sh up` from the Fabric getting started docs. What should my profile connection settings be to use that fabric from Composer playground?

dselman (Mon, 05 Jun 2017 18:02:49 GMT):
Please follow this install: https://hyperledger.github.io/composer/getting-started/using-playground-locally.html

tennenjl (Mon, 05 Jun 2017 18:06:18 GMT):
Quick question regarding a change to relationships found here: https://github.com/hyperledger/composer/issues/696 For our older code, when the value of the relationship id was returned, I don't believe it was fully qualified with the namespace, and the type, now it looks like it is returning resource:namespace.type#id Just wanted to validate that changed and also wanted to check if there was an API call I should be using to just get the id. Thanks!

dselman (Mon, 05 Jun 2017 18:08:16 GMT):
Correct -- the code used to assume that the type returned was the type defined by the model (bad assumption, because it can be any derived type).

dselman (Mon, 05 Jun 2017 18:10:49 GMT):
You can get the Id by calling getIdentifier()

dselman (Mon, 05 Jun 2017 18:11:21 GMT):
getFullyQualifiedIdentifier() will return the type#id

tennenjl (Mon, 05 Jun 2017 18:11:48 GMT):
@dselman Thanks!

davidoevans (Mon, 05 Jun 2017 18:27:18 GMT):
@dselman - i have the composer playground installed locally as per your link...and i'm now using the hlfabric connection profile. Are those the same default settings that would correspond to the default fabric install? i'm trying to create my own fabric and understand how to map the right settings to a composer profile.

dselman (Mon, 05 Jun 2017 18:49:04 GMT):
If you want to go further, I suggest following the Developer Install next: https://hyperledger.github.io/composer/getting-started/development-tools.html

dselman (Mon, 05 Jun 2017 18:49:17 GMT):
This will get you a local Fabric, with the local Composer tools

dselman (Mon, 05 Jun 2017 18:50:50 GMT):
Your connection profile will be created by the createComposerProfile.sh script in your hom dir

dselman (Mon, 05 Jun 2017 18:51:08 GMT):
As described here: https://hyperledger.github.io/composer/reference/connectionprofile.html

opiepj (Mon, 05 Jun 2017 19:20:44 GMT):
@dselman @sstone1 Hey quick question, If I've updated my network models... how do I update my typescript interface on the client application? Is there an auto update command or do I just have to write it out?

travin (Mon, 05 Jun 2017 19:54:06 GMT):

travin (Mon, 05 Jun 2017 19:54:26 GMT):
Hi Hyperledger Composer team. I'm from the White Paper WG and we're looking for someone to write the overview section about Composer as well as perhaps include a highlighted feature for that section. If you're interested, or know someone I should contact, please send me a private message about it.

davidoevans (Mon, 05 Jun 2017 20:01:04 GMT):
thanks @dselman - i've followed those steps...i then ran `docker run -d -p 8080:8080 hyperledger/composer-playground` and went to localhost:8080/profile where was able to import the connection.js that was generated. However, when I go to use the connection profile, it's just hung indicating 'Please wait: establishing connection...'. Is there somewhere I can check logs to see what it might be stuck on?

davidkel (Mon, 05 Jun 2017 20:26:25 GMT):
@davidoevans what level of fabric are you trying to connect to ? Is it running locally through docker ?

davidoevans (Mon, 05 Jun 2017 20:26:50 GMT):
it is running locally through docker

davidkel (Mon, 05 Jun 2017 20:27:09 GMT):
and the version of fabric ?

davidoevans (Mon, 05 Jun 2017 20:28:00 GMT):
v1.0.0-alpha (setup as per instructions dselman gave)

davidkel (Mon, 05 Jun 2017 20:28:54 GMT):
ok, suggest you have a read of this https://stackoverflow.com/questions/44117260/docker-version-of-composer-playground-is-not-able-to-connect-to-local-hlf-1-0-0 trying to just run the docker image version of playground to connect to a local fabric isn't so straight forward

sstone1 (Mon, 05 Jun 2017 20:29:44 GMT):
@travin I can take care of the white paper section - will PM you

davidoevans (Mon, 05 Jun 2017 20:30:03 GMT):
will take a look...thx @davidkel

opiepj (Mon, 05 Jun 2017 20:33:57 GMT):
@Jakeeyturner @sstone1 For the Angular generator, how are the typescript interfaces created?

sstone1 (Mon, 05 Jun 2017 20:36:45 GMT):
@opiepj they use the `TypescriptVisitor` class

sstone1 (Mon, 05 Jun 2017 20:36:46 GMT):

opiepj (Mon, 05 Jun 2017 20:37:26 GMT):
How do these get updated ?

opiepj (Mon, 05 Jun 2017 20:37:43 GMT):
If you change the network model definitions is there a way to update your client interfaces?

opiepj (Mon, 05 Jun 2017 20:37:56 GMT):
If so that would be really cool to mention in the tutorial

davidoevans (Mon, 05 Jun 2017 20:39:33 GMT):
@davidkel - that was quite helpful...thx again. now I need to clear the settings my local playground is using since even after restarting it on different docker network, it is still trying to connect to the old profile and I can't do anything...do you know where those settings are?

davidkel (Mon, 05 Jun 2017 20:41:41 GMT):
@davidoevans The information is kept in local storage in your browser. Depending on the brower there are different ways to clear local storage. The way I get around this is to run in an Incognito window if I don't want to clear my browser cache

sstone1 (Mon, 05 Jun 2017 20:41:54 GMT):
you can just re-run the generator, but that will overwrite any generated angular components - i don't think there's a way to just regen the typescript files

sstone1 (Mon, 05 Jun 2017 20:42:38 GMT):
@Jakeeyturner would know for sure

opiepj (Mon, 05 Jun 2017 20:43:37 GMT):
@sstone1 sounds like a feature I can build out ;)

sstone1 (Mon, 05 Jun 2017 20:43:50 GMT):
i like the sound of that ;)

sstone1 (Mon, 05 Jun 2017 20:44:06 GMT):
fancy adding participants and transactions whilst you're at it? :P

davidoevans (Mon, 05 Jun 2017 20:46:37 GMT):
that worked...thanks again @davidkel

opiepj (Mon, 05 Jun 2017 20:46:51 GMT):
@sstone1 participants and transactions whilst ?

davidkel (Mon, 05 Jun 2017 20:46:59 GMT):
@davidoevans that's good. Glad to help

opiepj (Mon, 05 Jun 2017 20:52:01 GMT):
@sstone1 okay I'll take a look

sstone1 (Mon, 05 Jun 2017 20:52:10 GMT):
:+1: thanks man!

sstone1 (Mon, 05 Jun 2017 20:52:32 GMT):
give @Jakeeyturner a shout if you need a hand with anything

opiepj (Mon, 05 Jun 2017 20:53:03 GMT):
What branch you want this on?

opiepj (Mon, 05 Jun 2017 20:54:26 GMT):
@sstone1 also can I remove Tether and Bootstrap? I can include a UI component library instead

sstone1 (Mon, 05 Jun 2017 20:55:24 GMT):
we do everything on `master`

sstone1 (Mon, 05 Jun 2017 20:55:59 GMT):
@winslet is our UI designer - worth a chat with him on the UI front maybe?

sstone1 (Mon, 05 Jun 2017 20:56:17 GMT):
i try to avoid doing UI stuff at all costs, not my forte ;)

opiepj (Mon, 05 Jun 2017 21:03:11 GMT):
@sstone1 I'll check with them as well

opiepj (Mon, 05 Jun 2017 21:03:36 GMT):
@sstone1 if this were to be a cli ability do you want this in the composer-cli or composer-client? I don't believe that is a cli

opiepj (Mon, 05 Jun 2017 21:04:31 GMT):
Actually nvm, makes sense for it to be part of yeoman as a subcommand

sstone1 (Mon, 05 Jun 2017 21:04:53 GMT):
ok cool - i think yeoman makes sense

sstone1 (Mon, 05 Jun 2017 21:05:03 GMT):
i was going to say there is this command i didn't know about

sstone1 (Mon, 05 Jun 2017 21:05:03 GMT):
there's currently this command

sstone1 (Mon, 05 Jun 2017 21:05:03 GMT):
https://github.com/hyperledger/composer/blob/master/packages/composer-cli/lib/cmds/generator/createCodeCommand.js

sstone1 (Mon, 05 Jun 2017 21:05:32 GMT):
it's possible you can today run `composer generator create --archiveFile digitialPropertyNetwork.bna --format Typescript --outputDir ./dev/go-app`

opiepj (Mon, 05 Jun 2017 21:08:00 GMT):
hmm didn't work for me

opiepj (Mon, 05 Jun 2017 21:08:56 GMT):
Error: Unrecognised type: object, value: BusinessNetworkDefinition {

sstone1 (Mon, 05 Jun 2017 21:16:54 GMT):
from the command itself?

opiepj (Mon, 05 Jun 2017 21:27:13 GMT):
yes

opiepj (Mon, 05 Jun 2017 21:27:25 GMT):
v7.4

opiepj (Mon, 05 Jun 2017 21:27:29 GMT):
0.7.4

opiepj (Mon, 05 Jun 2017 21:36:12 GMT):
@sstone1 Also this is really weird. So I'm creating multiple model files. When building out the transaction logic composer cannot find the assets in my namespace. When I condense all my models into one file it works...

Namespaces are all aligned

dselman (Mon, 05 Jun 2017 21:53:50 GMT):
A model file must have a unique namespace

opiepj (Mon, 05 Jun 2017 21:55:27 GMT):
Ah

opiepj (Mon, 05 Jun 2017 21:57:13 GMT):
Should it throw an error if you are using the same namespace twice?

dselman (Mon, 05 Jun 2017 21:58:02 GMT):
Yes -- that's a bug I think. I think because we store the model files in the model manager by namespace it probably just silently overwrites them

opiepj (Mon, 05 Jun 2017 22:00:14 GMT):
Okay that fixed my problem thank you!

dselman (Mon, 05 Jun 2017 22:02:49 GMT):
:thumbsup:

dselman (Mon, 05 Jun 2017 22:03:09 GMT):
Could you please create an issue to throw an exception if you add a duplicate ns to the model manager?

Sure

Hi, I have a specific question: My project team is trying to find a solution. Hyperledger Fabric Composer may pose a risk to our model, In particular, our models can include an Array of items, but we were wondering if it’s possible to use Dictionaries in the composer code instead of Arrays? If so, how can we do this?

opiepj (Mon, 05 Jun 2017 22:45:38 GMT):
@Jingleh You could build out a BST I suppose. I don't think that CTO supports maps

Can you please also share your views on following questions: 1) if We are using composer-rest-server, then will have to manage two server side components. 1) running composer-rest-server 2) running application which will send request to composer-rest-server to communicate to network. Isn't it overhead? what additional advantages we are getting by using composer-rest-server? in fact, probably client will have to authenticate two times i guess. 2) If we are using JavaScript SDK, then will have to manage only one server side application, right? 3) When i generated angularjs application using yo generator, its also asking me information of composer-rest-server, but I am not planning to use composer-rest-server and want to use 'composer-client' and 'composer-server' only.

I have the problem that I can't see any useful debug output after changing from V0.6 to v1.0. Before I could monitor the chaincode outputs via `docker attach`, now it barely shows any debug output. I have also modified the docker-compose.yaml file to set the peers into debug mode, doesn't seem to help. Any advice how to debug the chaincode properly?

davidkel (Tue, 06 Jun 2017 11:10:08 GMT):
@jje in the docker-compose.yml file, for the peer definitions you need to add `CORE_CHAINCODE_LOGLEVEL=DEBUG` to the environment section

Now for deploying my network (.bna) does each member have to deploy the .bna to its peers with its specific connection profile using SPChannel or any one member will deploy to its peers and it will available to peers corresponding to all other members on SPChannel

davidkel (Tue, 06 Jun 2017 11:45:01 GMT):
@vinitesh Every endorsing peer will need to have the business network installed. So each member should create a connection profile for deployment

[ ](https://chat.hyperledger.org/channel/composer?msg=CTiyuHhtLNb7JK55a) @dselman Per you response to the SO question ( https://stackoverflow.com/questions/44382503/overhead-to-using-composer-rest-server-over-javascript-node-sdk) and arch diagram...just so I'm clear would you consider the Client Tier using web browser something like an Angular app? Would would you see in the App Tier for technology? I've always had the picture in my head that the web browser would be going directly to the REST server so just want to make sure I'm not missing something technically.

vinitesh (Tue, 06 Jun 2017 11:55:52 GMT):
@davidkel In composer deploy command after installing it will also instantiate the genric chaincode . So what will happen if member1 has instantiated the grneric chaincode on the channel and member2 while deploying again try to instantiate the genric chaincode on the same channel?

davidkel (Tue, 06 Jun 2017 11:59:30 GMT):
@vinitesh The deploy command will return an error saying 'chaincode exists', but the chaincode will have been installed onto the peer. What should happen is when an invokechaincode is made to that peer, it will bring up the chaincode container to simulate the request for endorsement purposes. What I can't say is whether that works for alpha1 or not. I've been working with alpha2 and newer versions and have shown that to be the behaviour, but that is what should happen.

dselman (Tue, 06 Jun 2017 12:18:48 GMT):
@jdockter Yes, I'm thinking the Node.js / Apache process that is hosting the static/dynamic files for the Angular app.

caroline-church (Tue, 06 Jun 2017 12:21:44 GMT):
Hi @rama_rahul are either the member or company relationships in your model? If so when the transaction is submitted we will try and resolve the relationships, If they don't exist we will throw that error (i think the error needs improving)

selvaraman (Tue, 06 Jun 2017 12:22:27 GMT):
Has joined the channel.

jdockter (Tue, 06 Jun 2017 12:25:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=aQ3ZzunQSj46hrJt3) @dselman okay and what about the App Tier connected to the event hub? I haven't spent enough time on the new event capabilities but would that be a separate Node.js app running to catch emitted events sent from the busn network?

sstone1 (Tue, 06 Jun 2017 12:27:25 GMT):
@jdockter correct, yes it would be - until we can add web hook/websocket support to the REST server to remove the need for the Node.js app

sstone1 (Tue, 06 Jun 2017 12:27:46 GMT):
-or- you can use the cool new Node-RED capabilities to listen for events and send them into other systems

vinitesh (Tue, 06 Jun 2017 12:28:00 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=obDBqA8cBhGTvmZG5) you are right. Even in alpha1 during deployment for peer2 it gave me error that chaincode already exits but when i ping the network for peer2 , it brings up chaincode container for peer2:)

FelixNielsen (Tue, 06 Jun 2017 14:07:54 GMT):
when I run the composer locally and changed default ACL from ALLOW to DENY - I can still update asset via transactions? - is this intended/normal

caroline-church (Tue, 06 Jun 2017 14:13:46 GMT):
Can you show me your ACL file

caroline-church (Tue, 06 Jun 2017 14:13:46 GMT):
Hi @FelixNielsen Can you show me your ACL file please

jje (Tue, 06 Jun 2017 14:35:58 GMT):
@davidkel: I have now enabled the debug level as you describe, it outputs shim and composer debug info nicely, however my chaincode output comes out only *sporadically* (I output to 'stdout' and do a 'tee' like 'docker attach dev-peer1-property-network-0.7.3 | tee log_jje1.log'. So it is still hard to debug my own chaincode (javascript code). Any suggestion?

davidkel (Tue, 06 Jun 2017 14:37:40 GMT):
@jje for v1 I don't believe console.log works. I think it has been mentioned be that `print` should work

davidkel (Tue, 06 Jun 2017 14:37:40 GMT):
@jje for v1 I don't believe console.log works. I think it has been mentioned before that `print` should work

Hi all, Can someone please specify the path of .hfc-key-store on linux environment? Thanks

Fanarito (Tue, 06 Jun 2017 14:41:28 GMT):
@AccentSandy it should be in your home directory

hariharanatarajan (Tue, 06 Jun 2017 14:43:07 GMT):
@davidkel @sstone1 how do I debug connector issues . I tried a docker log -f confident_eulter and do not see any errors / movement . I have started the Fabric by hand and composer by hand . I have ensured that both of them are in the same network by using docker network inspect . When I use a browser and connect to localhost:8080 I see a message saying connecting and then no activity .

AccentSandy (Tue, 06 Jun 2017 14:44:04 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=bMPsRMn2QpYhLmTCx) Thanks @Fanarito. I have looked it into the home directory but it doesn't appear to be there. I am logged in as root user if that help to setup the hyperledger instance.

caroline-church (Tue, 06 Jun 2017 14:45:39 GMT):
Hi @hariharanatarajan which version of composer are you using

hariharanatarajan (Tue, 06 Jun 2017 14:48:23 GMT):
(https://chat.hyperledger.org/channel/composer?msg=wzdDog4oEmbmzCP6R) @caroline-church I pulled from the hub . This is what my docker images show . hyperledger/composer-playground latest 1f4a2a107534 11 days ago 335MB . The name of container was confident_euler if it gives any clue

DennisM330 (Tue, 06 Jun 2017 14:48:29 GMT):
@dselman I got the Composer

caroline-church (Tue, 06 Jun 2017 14:50:14 GMT):
@hariharanatarajan does the message say it is deploying the sample?

@dselman I got the composer rest server running in Bluemix as a CF app connecting to my Blockchain network in Bluemix. Curious on best way to make the connection profile and rest rest server parameters configurable in Bluemix.

nope . Trying it for the first time

hariharanatarajan (Tue, 06 Jun 2017 14:55:01 GMT):
I am sure I have something wrong . I am trying to figure out where would the logs show . I figured out there should be on the same docker network ..and have included that

caroline-church (Tue, 06 Jun 2017 14:57:35 GMT):
can you send me your connection profile please

caroline-church (Tue, 06 Jun 2017 14:57:54 GMT):
Does playground work ok in web mode?

hariharanatarajan (Tue, 06 Jun 2017 14:58:43 GMT):
yes it does

jje (Tue, 06 Jun 2017 14:58:55 GMT):
@davidkel This works, thanks a lot!

hariharanatarajan (Tue, 06 Jun 2017 14:59:29 GMT):
I have managed to deploy a sample of the animal trading with 1 transaction , 2 assets , 4 owners etc

caroline-church (Tue, 06 Jun 2017 15:00:02 GMT):
Was this a deploy to web mode or to a fabric?

hariharanatarajan (Tue, 06 Jun 2017 15:03:29 GMT):
this is the sequence I did if that helps : Started playground using the command ``` 1) docker run -d -p 8080:8080 hyperledger/composer-playground ``` 2) I was able to define assets and deploy in the web browser mode ``` 3) Now I wanted to define a connection . Gave the parameters and clicked on use this ``` 4) I stopped the container and created a docker-compose file so that the playground will be on the same network as the fabric ``` 4) I start using docker-compose -f xxx up -d and then this happens ..

caroline-church (Tue, 06 Jun 2017 15:04:23 GMT):
can you show me what you put in the connection profile properties, and can you show me the docker-compose file

FelixNielsen (Tue, 06 Jun 2017 15:05:02 GMT):
@caroline-church /** * Sample access control list. */ rule Default { description: "Allow all participants access to all resources" participant: "ANY" operation: ALL resource: "org.acme.sample" action: DENY }

caroline-church (Tue, 06 Jun 2017 15:07:07 GMT):
@FelixNielsen if you use the admin id then the access control enforcement is disabled. This is because the admin id isn't bound to a participant

caroline-church (Tue, 06 Jun 2017 15:07:17 GMT):
this is something we are looking to fix

FelixNielsen (Tue, 06 Jun 2017 15:07:32 GMT):
@caroline-church alright thanks!

hariharanatarajan (Tue, 06 Jun 2017 15:09:28 GMT):
` version: '2' services: playground: image: hyperledger/composer-playground environment: - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2ecli_default ports: - "8080:8080" container_name: confident_euler1 ` is the docker-compose file .. I did not have the properties file . I guess it must have picked it from the last version I did before stopping and restarting

caroline-church (Tue, 06 Jun 2017 15:11:14 GMT):
You can export the connection profile from the browser

hariharanatarajan (Tue, 06 Jun 2017 15:18:23 GMT):
I am unable to . Let me do one thing . I will clear it up and start the playground from scratch and report any errors

caroline-church (Tue, 06 Jun 2017 15:18:31 GMT):
ok

hariharanatarajan (Tue, 06 Jun 2017 15:21:19 GMT):
Hi would you know how do go back to a clean container . I tried docker stop confident_euler followed by docker rm confident_euler and then did a docker-compose up -d and the connection is still retained ?

caroline-church (Tue, 06 Jun 2017 15:22:23 GMT):
try `docker-compose kill && docker-compose down`

caroline-church (Tue, 06 Jun 2017 15:22:23 GMT):
try `docker-compose kill && docker-compose down` to tear it down

hariharanatarajan (Tue, 06 Jun 2017 15:24:05 GMT):
Tried . Does not seem to help

hariharanatarajan (Tue, 06 Jun 2017 15:24:34 GMT):
The moment my browser connects I get a message saying "using FabConnection profile "

caroline-church (Tue, 06 Jun 2017 15:25:33 GMT):
ok maybe try following these instructions. It will download the docker images for fabric and playground and then create a connection profile for you

caroline-church (Tue, 06 Jun 2017 15:27:46 GMT):
https://hyperledger.github.io/composer/getting-started/using-playground-locally.html

hariharanatarajan (Tue, 06 Jun 2017 15:33:09 GMT):
ok . I did this because I have a local version of Fabric that I build and hence wanted to use that ..

caroline-church (Tue, 06 Jun 2017 15:35:01 GMT):
ok how about if you clear your browser local storage. Then refresh the browser. This will put you back into web mode

caroline-church (Tue, 06 Jun 2017 15:36:04 GMT):
before that what version of fabric are you using?

hariharanatarajan (Tue, 06 Jun 2017 15:44:59 GMT):
ok . tried that . . This is the connection profile `{ "name": "HariConnection", "description": "A description for a V1 Profile", "type": "hlfv1", "orderers": [ { "url": "grpc://orderer.example.com:7050", "cert": "", "hostnameOverride": "" } ], "channel": "harichan", "mspID": "Org1MSP", "ca": "http://ca_peerOrg1:7054", "peers": [ { "requestURL": "grpc://peer1.org1.example.com:7051", "eventURL": "grpc://peer0.org2.example.com:7053", "cert": "", "hostnameOverride": "" } ], "keyValStore": "/tmp/keyValStore", "deployWaitTime": 300, "invokeWaitTime": 30 }`

hariharanatarajan (Tue, 06 Jun 2017 15:45:35 GMT):
and I get the same results . The moment I hit the connect it just keeps spinning

caroline-church (Tue, 06 Jun 2017 15:46:27 GMT):
on the `requestURL` are you using that exact value or have you changed it for showing it to me.

hariharanatarajan (Tue, 06 Jun 2017 15:47:07 GMT):
this is what I am running

jdockter (Tue, 06 Jun 2017 15:47:39 GMT):
When using the playground if I replace my current busn network with a new BNA do I revoke any identifies I have previously created?

hariharanatarajan (Tue, 06 Jun 2017 15:47:43 GMT):
I am using the e2e_cli from the hyperledger fabric code base ..

hariharanatarajan (Tue, 06 Jun 2017 15:48:45 GMT):
I have one basic question . For the identity I used the private key of the user1 that was generated by the cryptoconfig utility

jdockter (Tue, 06 Jun 2017 15:48:47 GMT):
My wallet shows them but when I go to use them they are 'invalid or may have been revoked'

hariharanatarajan (Tue, 06 Jun 2017 15:49:18 GMT):
So I picked up the private key as is ( i.e.) copy paste including the begin end etc..

caroline-church (Tue, 06 Jun 2017 15:49:23 GMT):
is that definitely what your peer is called?

caroline-church (Tue, 06 Jun 2017 15:49:59 GMT):
the `keyValStore` should be set to `/home/composer/.hfc-key-store`

hariharanatarajan (Tue, 06 Jun 2017 15:50:16 GMT):

caroline-church (Tue, 06 Jun 2017 15:51:01 GMT):
the `keyValStore` is definately wrong though

caroline-church (Tue, 06 Jun 2017 15:51:01 GMT):
the `keyValStore` is definately wrong though and should be `/home/composer/.hfc-key-store`

hariharanatarajan (Tue, 06 Jun 2017 15:51:43 GMT):
Can u also let me know the Identity ? Am I doing it wrong ?

jdockter (Tue, 06 Jun 2017 15:51:48 GMT):
@sstone1 doesn't seem like I can do anything with these identities now they are revoked in the wallet, is that correct?

caroline-church (Tue, 06 Jun 2017 15:52:11 GMT):
@jdockter thats because the participants that the identity is associated with don't exist on the new business network

caroline-church (Tue, 06 Jun 2017 15:52:58 GMT):
the default identity on aplpha1 is `admin` and `adminpw`

guyho (Tue, 06 Jun 2017 15:53:09 GMT):
Are there any examples of complex transactions, i.e., creation of an asset also creates relationship to an existing asset?

guyho (Tue, 06 Jun 2017 15:53:09 GMT):
Are there any examples of complex transactions, i.e., creation of an asset also creates relationship to an existing asset? I'm thinking this somehow relates to the newRelationship function in composer-runtime.

jdockter (Tue, 06 Jun 2017 15:53:30 GMT):
@caroline-church I did an Import/Replace, but my Wallet still shows the IDs that I had created and can't seem to do anything with them now

jdockter (Tue, 06 Jun 2017 15:53:52 GMT):
yes admin / adminpw works

caroline-church (Tue, 06 Jun 2017 15:54:32 GMT):
@jdockter thats becuase the wallet is per connection profile so will still be there

caroline-church (Tue, 06 Jun 2017 15:55:01 GMT):
@hariharanatarajan try running ` docker exec -ti CONTAINER_ID_OF_PLAYGROUND sh` and the `ping `

jdockter (Tue, 06 Jun 2017 15:56:23 GMT):
@caroline-church okay...so on each Import/Replace I need to reissue identities? and there is no way via the playground to remove or reissue the same identity?

caroline-church (Tue, 06 Jun 2017 15:56:43 GMT):
@guyho the vehicle lifecycle sample network has example of this. If you look in the setup script it shows how to do it

guyho (Tue, 06 Jun 2017 15:57:09 GMT):
@caroline-church cool! thanks for the pointer.

caroline-church (Tue, 06 Jun 2017 15:57:12 GMT):
@jdockter no you can't revoke identites in playground yet. There is a story for it

jdockter (Tue, 06 Jun 2017 15:58:15 GMT):
@caroline-church if I installed the playground via npm would I be able to manage this via the cli?

hariharanatarajan (Tue, 06 Jun 2017 15:58:51 GMT):
```~ $ /bin/ping peer1.org1.example.com PING peer1.org1.example.com (172.20.0.8): 56 data bytes ping: permission denied (are you root?) ~ $ sudo su sh: sudo: not found ```

hariharanatarajan (Tue, 06 Jun 2017 16:02:23 GMT):
My docker network inspect shows all the containers to be in the same network .

caroline-church (Tue, 06 Jun 2017 16:03:50 GMT):
@jdockter you can don't need to install playground via npm you can still use the cli

jdockter (Tue, 06 Jun 2017 16:05:12 GMT):
@caroline-church not sure I follow your comment

caroline-church (Tue, 06 Jun 2017 16:05:31 GMT):
@hariharanatarajan can you do that for all the things in your network

hariharanatarajan (Tue, 06 Jun 2017 16:05:36 GMT):
I thought I will try the reverse (i.e.) get into the peer1.org1.example.com and ping the composer but I get ```Linux 2ddf5a7f7773 4.4.0-78-generic #99-Ubuntu SMP Thu Apr 27 15:29:09 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ping not found``` hard luck :-(

caroline-church (Tue, 06 Jun 2017 16:06:28 GMT):
@jdockter you can use the cli regardless of how you installed playground. And yes you can use the cli to issue and revoke identities

hariharanatarajan (Tue, 06 Jun 2017 16:08:32 GMT):

hariharanatarajan (Tue, 06 Jun 2017 16:09:18 GMT):
I suspect I am using the wrong values for the identity

jdockter (Tue, 06 Jun 2017 16:09:28 GMT):
@caroline-church when I issued the identities I did not see them in my local .hfc-key-store so I figured they were in the docker container ...so are you saying that from outside the container I should be able to connect with those identities?

caroline-church (Tue, 06 Jun 2017 16:09:55 GMT):
@hariharanatarajan did you try updating the `keyValStore`?

caroline-church (Tue, 06 Jun 2017 16:10:03 GMT):
what values did you use for the identity?

hariharanatarajan (Tue, 06 Jun 2017 16:13:12 GMT):
This is the userId User1@org1.example.com and the I used the private key found in the file under msp

hariharanatarajan (Tue, 06 Jun 2017 16:14:39 GMT):
@caroline-church thanks for all the help . I need to go . Will update this thread with the results I get tomorrow . thanks once again

caroline-church (Tue, 06 Jun 2017 16:15:40 GMT):
@jdockter to remove the identities from your wallet in playground you would need to clear your local storage but you still wouldn't be able to use those ids as the exist on the fabric (you would need to delete your fabric)

jdockter (Tue, 06 Jun 2017 16:19:56 GMT):
@caroline-church delete my .hfc-key-store or the Fabric containers, ie CA, orderer, peers, etc.?

caroline-church (Tue, 06 Jun 2017 16:20:35 GMT):
@jdockter the fabric containers

jdockter (Tue, 06 Jun 2017 16:25:02 GMT):
@caroline-church so doesn't the update cli command key all the identities in place?

jdockter (Tue, 06 Jun 2017 16:27:21 GMT):
I must be missing something...are these the steps to have my identities ...1) deploy my BNA to Fabric ...2) Issue identities for my participants in BNA...3) make changes to BNA ..4) restart Fabric containers ...5) deploy BNA again....6) issue identities again ?

caroline-church (Tue, 06 Jun 2017 16:29:04 GMT):
I'm not really sure what you are trying to achieve

caroline-church (Tue, 06 Jun 2017 16:29:04 GMT):
@jdockter I'm not really sure what you are trying to achieve

jdockter (Tue, 06 Jun 2017 16:30:08 GMT):
@caroline-church I want to issue identities for participants AND make changes to me business network many times over

jdockter (Tue, 06 Jun 2017 16:30:08 GMT):
@caroline-church I want to issue identities for participants AND make changes to my business network many times over

caroline-church (Tue, 06 Jun 2017 16:33:33 GMT):
this should be ok if you are just making changes it will only be a problem if you import a business network as this will do a deploy rather than an update

jdockter (Tue, 06 Jun 2017 16:42:51 GMT):
ah okay...so the Deploy button is doing an `composer network update` and the Import/Replace is doing a 'composer network deploy` ?

okay

davidkel (Tue, 06 Jun 2017 16:46:05 GMT):
@caroline-church what happens on hlfv1 if you try to replace a business network with another one of the same ?

davidkel (Tue, 06 Jun 2017 16:46:05 GMT):
@caroline-church what happens on hlfv1 if you try to replace a business network with another one of the same, eg for example you update it through the import/replace ?

caroline-church (Tue, 06 Jun 2017 16:48:07 GMT):
@davidkel if you do it through playground it always uses the business network name `org.acme.biznet` so it does a reset to delete everything then does a deploy

davidkel (Tue, 06 Jun 2017 16:49:46 GMT):
@caroline-church I would expect the deploy to fail if it used the same business network as it will have been deployed already

jdockter (Tue, 06 Jun 2017 16:50:43 GMT):
@caroline-church okay so setup playground via npm rather than docker container and now I see identities in hfc-key-store that I issued via the playground...so will just use CLI to update org.acme.biznet from my local

caroline-church (Tue, 06 Jun 2017 16:51:07 GMT):
@davidkel try it and see what happens

caroline-church (Tue, 06 Jun 2017 16:52:51 GMT):
@jdockter you can still use the playground to update your business network, just don't do an import after you have issued the identities always just click the deploy button

jdockter (Tue, 06 Jun 2017 16:56:20 GMT):
@caroline-church was trying to keep my code in VSCode...maybe this won't work

caroline-church (Tue, 06 Jun 2017 16:57:23 GMT):
@jdockter ahh ok, so when you deploy do a `composer network update` rather than a `composer network deploy`

jdockter (Tue, 06 Jun 2017 16:59:29 GMT):
@caroline-church well it doesn't seem to like my bna name on the update

caroline-church (Tue, 06 Jun 2017 17:01:05 GMT):
what does it say

jdockter (Tue, 06 Jun 2017 17:01:34 GMT):
```jdockter@ubuntu:~/github/customs/network$ composer network update -p hlfv1 -a customs-network@0.0.1.bna -i admin -s adminpw Deploying business network from archive: customs-network@0.0.1.bna Business network definition: Identifier: customs-network@0.0.1 Description: Customs Network Error: failed to obtain cds for customs-network - transaction not found customs-network/mychannel Command failed ```

caroline-church (Tue, 06 Jun 2017 17:04:43 GMT):
@jdockter Is that business network deployed, if so did you deploy it through the playground? if you did then the business network name will be `org.acme.biznet`

jdockter (Tue, 06 Jun 2017 17:06:07 GMT):
@caroline-church yup it was...but the update needs the archive file right? so would I have to rename my archive?

jdockter (Tue, 06 Jun 2017 17:09:48 GMT):
this did not work either...```jdockter@ubuntu:~/github/customs/network$ composer network update -p hlfv1 -a org.acme.network@0.0.1.bna -i admin -s adminpw Deploying business network from archive: org.acme.network@0.0.1.bna Business network definition: Identifier: org.acme.network@0.0.1 Description: Customs Network Error: failed to obtain cds for org.acme.network - transaction not found org.acme.network/mychannel Command failed ```

jdockter (Tue, 06 Jun 2017 17:09:59 GMT):
whoops

jdockter (Tue, 06 Jun 2017 17:10:14 GMT):
that should be biznet

jdockter (Tue, 06 Jun 2017 17:10:43 GMT):
better :)

@dselman OK, but how do I create them from the transaction list shown above

jdockter (Tue, 06 Jun 2017 17:49:58 GMT):
for example I want participant A to have CREATE access to resource B or C...so the if would be on the resource parameter to say B or C

jje (Tue, 06 Jun 2017 17:50:02 GMT):
@dselman Is there any example I could look at?

dselman (Tue, 06 Jun 2017 17:56:08 GMT):
You can read each case out of its asset registry using a 'get' and then push the result onto the end of your case array.

dselman (Tue, 06 Jun 2017 17:57:22 GMT):
You will have to be careful to aggregate all your promises however, and return a Promise.all(promises)

jje (Tue, 06 Jun 2017 17:58:07 GMT):
OK, will try, thanks for now!

torresjeff (Tue, 06 Jun 2017 18:00:21 GMT):
@dselman do the github issues have any specific tag for anyone who wants to contribute? outside of the composer team?

tennenjl (Tue, 06 Jun 2017 18:41:01 GMT):
@jdockter Did you see the docs here: https://hyperledger.github.io/composer/reference/acl_language.html

tennenjl (Tue, 06 Jun 2017 18:41:49 GMT):
@jdocter rule SampleConditionalRule { description: "Description of the ACL rule" participant(m): "org.acme.SampleParticipant" operation: ALL resource(v): "org.acme.SampeAsset" condition: (v.owner.getIdentifier() == m.getIdentifier()) action: ALLOW }

jdockter (Tue, 06 Jun 2017 18:46:11 GMT):
@tennenjl yes...maybe I'm understanding something incorrectly, but I thought we could have a 'if' statement in the resource field...don't really need a condition...so resource: if ( "org.acme.SampeAssetA" or "org.acme.SampeAssetB")

jdockter (Tue, 06 Jun 2017 18:47:31 GMT):
I want one rule that allows one participant to CREATE several different resources

tennenjl (Tue, 06 Jun 2017 18:49:33 GMT):
@jdocter, ah I don't know. I would either have created separate rules for each resource or have the resources in the same class

davidkel (Tue, 06 Jun 2017 18:50:47 GMT):
@tmfukuda If it works with a 1 peer setup but not a 4 peer setup, how about a 2 peer setup ? Maybe worth trying on another channel where fabric developers hang out to see if they know of any issues or setup requirements for environments with more than 1 peer ?

jdockter (Tue, 06 Jun 2017 18:54:00 GMT):
@tennenjl resources in the same class?

tennenjl (Tue, 06 Jun 2017 18:54:44 GMT):
@jdocter, yes. According to the docs - Resource defines the things that the ACL rule applies to. This can be a property on a class, an entire class or all classes within a namespace. It can also be an instance of a class.

tennenjl (Tue, 06 Jun 2017 18:58:17 GMT):
@jdocter, I haven't tried this, but perhaps if you had a super type (e.g. animals) and then had asset types that extended the animals type, then perhaps you could do something that way?

dselman (Tue, 06 Jun 2017 19:01:11 GMT):
@jdockter you can call resource.getFullyQualifiedType() to get the FQN of the type of the resource. You can then use that in your condition statement.

dselman (Tue, 06 Jun 2017 19:02:26 GMT):
You could also use resource.instanceOf(fqn) if you want to do a type check that takes into account the inheritance hierarchy.

jdockter (Tue, 06 Jun 2017 19:44:06 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=P5FZEBBr3M8KYLBur) @dselman @tennenjl the scenario I have is one resource is a transaction and the other is an asset...so I want the participant to be able to create, via REST CRUD, and also create, via transaction. Maybe it's better to only allow the transaction which eventually will have more business logic in validating the data. Right now it just seemed like I had to write separate rules for each resource.

sstone1 (Tue, 06 Jun 2017 20:14:06 GMT):
@vni

sstone1 (Tue, 06 Jun 2017 20:14:22 GMT):
@vinitesh no, you cannot do that today

sstone1 (Tue, 06 Jun 2017 20:15:07 GMT):
@StephaneMery no, you cannot do that today - we are working on adding a `Transaction` base class (as part of core system types) that you might be able to use in the future though.

StephaneMery (Tue, 06 Jun 2017 20:21:53 GMT):
yep, make sense. Same thing for Asset and Participant I assume. Another need that will probably come soon is the ability to implement n-ary relations as map. Arrays are not the most efficient data structure to store large collections

@tennenjl don't remove the \n\r when editing the connection.json file, I need to look at what works and what doesn't in more detail but it appears for now that if you remove the \r then it doesn't work. I've not had a need to make use of the trusted roots option when working with service provided CAs as yet or my own local env when using tls.

here it refers to them as mantainers of the network

dselman (Wed, 07 Jun 2017 08:12:26 GMT):
@GrahamCharters can you create an issue please and attach BNA, logs etc and we will take a look

dselman (Wed, 07 Jun 2017 08:15:05 GMT):
@Pere-Lluis Composer doesn't deal with the structure/topology of the underlying HLF. You use HLF tools to manage the peers in the network etc. Please use the #fabric channel and docs.

Pere-Lluis (Wed, 07 Jun 2017 08:15:37 GMT):
oh thank you dselman!

Pere-Lluis (Wed, 07 Jun 2017 08:16:26 GMT):
but just one doubt, I can set the nodes through HLF and then deploy the bna with composer right?

caroline-church (Wed, 07 Jun 2017 08:19:07 GMT):
@Pere-Lluis yes

Pere-Lluis (Wed, 07 Jun 2017 08:19:33 GMT):
Thank you very much to both of you!

dselman (Wed, 07 Jun 2017 08:35:42 GMT):
@GrahamCharters you might also want to check the unit test for `describe('#privateVehicleTransfer', function() {` -- that transaction type is being tested.

GrahamCharters (Wed, 07 Jun 2017 08:42:38 GMT):
@dselman - thanks. It's difficult for me to tell from the test case whether or not I'm doing something wrong. I really need an example of the json I should be sending. I'm trying it out through the API Explorer.

Hello, I am currently trying to generate the business network archive as per the instructions on this page: https://hyperledger.github.io/composer/tutorials/developer-guide.html However when I carry out the following step, I do not get the expected result. To check that the structure of the files is valid, you can now generate a Business Network Archive (BNA) file for your business network definition. The BNA file is the deployable unit -- a file that can be deployed to the Composer runtime for execution. Switch back to the terminal and type: npm install Expected result: creation of .bna file in list folder. Actual output: harjots-air:~ harjotrahi$ npm install npm notice created a lockfile as package-lock.json. You should commit this file. npm WARN harjotrahi No description npm WARN harjotrahi No repository field. npm WARN harjotrahi No license field. added 263 packages in 13.242s Has anyone seen this before?

caroline-church (Wed, 07 Jun 2017 08:51:24 GMT):
Can you show what your package.json looks like

dselman (Wed, 07 Jun 2017 08:51:26 GMT):
@harj91 I suspect you missed this step: `(Note: Remove the 'deploy' line after 'test' - as we will not be publishing this network to the npm package manager).`

harj91 (Wed, 07 Jun 2017 09:05:14 GMT):
@dselman the deploy line is not in my package.json file - here is what it looks like atm:

harj91 (Wed, 07 Jun 2017 09:05:14 GMT):

dselman (Wed, 07 Jun 2017 09:06:17 GMT):
Did you complete the Development Tools install? What version of npm and Node do you have?

dselman (Wed, 07 Jun 2017 09:07:12 GMT):
Did you check whether the BNA file was created in the /dist folder?

dselman (Wed, 07 Jun 2017 09:07:27 GMT):
Those look like warnings...

Jakeeyturner (Wed, 07 Jun 2017 09:08:36 GMT):
Would the prepublish script even execute if npm install is called?

Vipul_Bajaj (Wed, 07 Jun 2017 09:10:57 GMT):
I have a use case in which there is an asset which is owned by two participants and there are other participants too. Now ,I want that only those two participants should be able to update anything in the assets through transactions and if any other participant tries to update data should not be able to do that.

dselman (Wed, 07 Jun 2017 09:11:19 GMT):
@Jakeeyturner short answer is yes... except apparently on npm5?

harj91 (Wed, 07 Jun 2017 09:11:22 GMT):
i have node version 6.10.3 and npm version 5.0.3. as far as I can see the BNA file has not been created

caroline-church (Wed, 07 Jun 2017 09:11:39 GMT):
@harj91 try using node version 4

caroline-church (Wed, 07 Jun 2017 09:12:10 GMT):
@Vipul_Bajaj you need to create an acl file

caroline-church (Wed, 07 Jun 2017 09:12:10 GMT):
@Vipul_Bajaj you need to create an acl file this allows you to specify rules on who can do things with the business network

Vipul_Bajaj (Wed, 07 Jun 2017 09:12:26 GMT):
@caroline-church I tried but no effect

caroline-church (Wed, 07 Jun 2017 09:12:57 GMT):
@Vipul_Bajaj can you show me the acl file you have created

dselman (Wed, 07 Jun 2017 09:13:23 GMT):
@harj91 so, it seems that the behavior of npm prepublish has changed in npm5... :-/

dselman (Wed, 07 Jun 2017 09:13:26 GMT):
IMPORTANT: As of npm@5, prepublish will only be run for npm publish. This will make its behavior identical to prepublishOnly, so npm@6 or later may drop support for the use of prepublishOnly, and then maybe we can all forget this embarrassing thing ever happened.

dselman (Wed, 07 Jun 2017 09:13:50 GMT):
On npm4 it also runs on `npm install` (for a local package)

caroline-church (Wed, 07 Jun 2017 09:13:50 GMT):
@Vipul_Bajaj Also are you using the admin user, if so acl rules aren't applied as they aren't associated with a participant

dselman (Wed, 07 Jun 2017 09:14:30 GMT):
@harj91 so, please use npm4

Vipul_Bajaj (Wed, 07 Jun 2017 09:15:50 GMT):
This is the acl file I have created.rule r1{ description: "Allow the owner of a vehicle total access" participant(m): "org.blockchainv1.participant1" operation: ALL resource(v): "org.blockchainv1.Record" condition: (v.participant1.getIdentifier() == m.getIdentifier()) action: ALLOW } rule R2{ description: "Allow the owner of a vehicle total access" participant(m): "org.blockchainv1.Participant1" operation: ALL resource(v): "org.blockchainv1.Record" condition: (v.participant1.getIdentifier() == m.getIdentifier()) action: ALLOW }

@caroline-church how to change the user in composer playground

caroline-church (Wed, 07 Jun 2017 09:17:22 GMT):
In the header bar if you click on where it says admin it allows you to create new identities and switch between them

Vipul_Bajaj (Wed, 07 Jun 2017 09:17:40 GMT):
@caroline-church thanks

Vipul_Bajaj (Wed, 07 Jun 2017 09:17:56 GMT):
@caroline-church Is my acl file correct

caroline-church (Wed, 07 Jun 2017 09:17:58 GMT):
also on the acl rules in the first rule you have the participant with a lower case p but on rule 2 you have participant with an uppercase p

Vipul_Bajaj (Wed, 07 Jun 2017 09:18:23 GMT):
@caroline-church ok

indira.kalagara (Wed, 07 Jun 2017 09:21:05 GMT):

Hi, We tried this https://hyperledger.github.io/composer/integrating/deploying-the-rest-server.html we are getting error when trying to follow the steps given.. Error: Private key missing from key store. Can not establish the signing identity for user admin

caroline-church (Wed, 07 Jun 2017 09:35:29 GMT):
Hi @karthikworks what did you set the `COMPOSER_ENROLLMENT_ID` and `COMPOSER_ENROLLMENT_SECRET` environment variables to?

karthikworks (Wed, 07 Jun 2017 09:36:00 GMT):
Hi @caroline-church its admin and adminpw

FelixNielsen (Wed, 07 Jun 2017 09:36:37 GMT):
when I try to create a new user / participant -> I get this error : Invalid fully qualified participant identifier - what is the format for each field user/participant

caroline-church (Wed, 07 Jun 2017 09:37:55 GMT):
Hi @FelixNielsen Can you show me how the participant is modelled and how you are trying to create it

karthikworks (Wed, 07 Jun 2017 09:38:03 GMT):

carauction-network -> abstract participant User identified by email { o String email o String firstName o String lastName }

FelixNielsen (Wed, 07 Jun 2017 09:38:58 GMT):
(I guess)

FelixNielsen (Wed, 07 Jun 2017 09:39:07 GMT):
demo network

dselman (Wed, 07 Jun 2017 09:40:11 GMT):
@FelixNielsen that participant is declared as abstract -- you won't be able to create an instance of it.

FelixNielsen (Wed, 07 Jun 2017 09:40:33 GMT):
so I can't test ACL with the demos?

dselman (Wed, 07 Jun 2017 09:41:17 GMT):
You can, but you'll need to create with a non-asbtract participant type. I.e something that extends User but that is not abstract.

dselman (Wed, 07 Jun 2017 09:41:17 GMT):
You can, but you'll need to create a non-abstract participant type. I.e something that extends User but that is not abstract.

caroline-church (Wed, 07 Jun 2017 09:42:14 GMT):
@FelixNielsen so in the case of using the carauction network you need to create a member or auctioneer

FelixNielsen (Wed, 07 Jun 2017 09:45:51 GMT):
Sorry I don't quite understand it - how can I create identites and test "login" and ACLs

Vipul_Bajaj (Wed, 07 Jun 2017 09:49:08 GMT):
How can I delete identities in playground

caroline-church (Wed, 07 Jun 2017 09:49:38 GMT):
@Vipul_Bajaj you can't yet delete identities in playground there is a user story for it

caroline-church (Wed, 07 Jun 2017 09:50:45 GMT):
@FelixNielsen to create identities in playground you need to go to the identities page (click on where it says admin in the header bar) then you can issue idenities

FelixNielsen (Wed, 07 Jun 2017 09:51:20 GMT):
yes but what is the format for the two fields?

caroline-church (Wed, 07 Jun 2017 09:52:33 GMT):
oh, the userId can be any string of characters, and the participant needs to be the fully qualified participant, there is auto complete on that field so if you start typing the participant id it will auto complete

FelixNielsen (Wed, 07 Jun 2017 09:52:48 GMT):
thx let me try

when I run the command composer network deploy -a my-network.bna -p hlfv1 -i admin -s adminpw

Pere-Lluis (Wed, 07 Jun 2017 09:58:34 GMT):
I get the following error

Pere-Lluis (Wed, 07 Jun 2017 09:58:46 GMT):
events.js:160 throw er; // Unhandled 'error' event ^ Error: Connect Failed at ClientDuplexStream._emitStatusIfDone (/usr/lib/node_modules/composer-cli/node_modules/fabric-client/node_modules/grpc/src/node/src/client.js:201:19) at ClientDuplexStream._readsDone (/usr/lib/node_modules/composer-cli/node_modules/fabric-client/node_modules/grpc/src/node/src/client.js:169:8)

Pere-Lluis (Wed, 07 Jun 2017 09:59:12 GMT):
the network is the one given as example in: http://hyperledger-fabric.readthedocs.io/en/latest/getting_started.html

Pere-Lluis (Wed, 07 Jun 2017 09:59:35 GMT):
and I have created the ComposerProfile

Pere-Lluis (Wed, 07 Jun 2017 10:00:25 GMT):
It works well when I use the network generated by startfabric.sh given in the Composer tutorial

dselman (Wed, 07 Jun 2017 10:01:15 GMT):
@Pere-Lluis those Fabric instructions are for Alpha2 -- Composer only supports HLF Alpha1 at the moment.

Pere-Lluis (Wed, 07 Jun 2017 10:02:02 GMT):
So there's no way of deploying a bna on Alpha2 yet?

dselman (Wed, 07 Jun 2017 10:02:43 GMT):
We are tracking HLF progress as closely as we can but due to API changes it required some time for us to validate a new HLF release. We hope to support Alpha3 (which will be released by the HLF team this week) for our release next week. Fingers crossed!

dselman (Wed, 07 Jun 2017 10:02:58 GMT):
@Pere-Lluis no

Pere-Lluis (Wed, 07 Jun 2017 10:03:09 GMT):
Of course, I don't say it as a complain

Pere-Lluis (Wed, 07 Jun 2017 10:03:19 GMT):
thanks for all development

karthikworks (Wed, 07 Jun 2017 10:03:26 GMT):
@caroline-church /home/composer/.hfc-key-store is the keyValStore we have mentioned...

dselman (Wed, 07 Jun 2017 10:03:30 GMT):
No offense taken! :-)

dselman (Wed, 07 Jun 2017 10:04:32 GMT):
@Pere-Lluis the good news for Composer users is that their BNAs work unchanged across 0.6, Alpha1 and whatever is next...

dselman (Wed, 07 Jun 2017 10:12:41 GMT):
The licchk checks that all the source files have the header specified in header.txt. You've probably got a typo somewhere.

I have not updated either of them. I am running node v6.8.1 and npm v5.0.3 if that helps

@here -- it is much easer for us to answer your in depth questions if you create StackOverflow entries tagged with `hyperledger-composer` -- it allows you to attach logs etc and it naturally "threaded", and answers/questions are much less likely to be missed.

looks like i need to upgrade node and npm

harj91 (Wed, 07 Jun 2017 11:47:29 GMT):
@dselman thanks - i tried that originally and it led to this error

harj91 (Wed, 07 Jun 2017 11:48:03 GMT):
with latest versions of node and npm the original error still apparent: Error: Failed to load connector module "composer-connector-embedded" for connection profile "defaultProfile" at connectionProfileStore.load.then.e (node_modules/composer-common/lib/connectionprofilemanager.js:148:27)

caroline-church (Wed, 07 Jun 2017 12:03:06 GMT):
@harj91 you need to be on node v6 and npm v4

hariharanatarajan (Wed, 07 Jun 2017 12:05:08 GMT):
@caroline-church Is there a piece of code that creates the $HOME/.hfc-key-store

Vipul_Bajaj (Wed, 07 Jun 2017 12:05:16 GMT):
Can we provide dynamic access to some participants if required.

caroline-church (Wed, 07 Jun 2017 12:06:46 GMT):
@hariharanatarajan the key-store gets created when you first enroll with an identity

caroline-church (Wed, 07 Jun 2017 12:07:04 GMT):
@Vipul_Bajaj I'm not sure i understand what you mean

harj91 (Wed, 07 Jun 2017 12:07:45 GMT):
@caroline-church thanks ill give it a go

Vipul_Bajaj (Wed, 07 Jun 2017 12:10:19 GMT):
Like I own a record that's an asset. Now I want to share some info with some other participant of the network and want to give a partial access to fields of the record. So is it possible in composer

karthikworks (Wed, 07 Jun 2017 12:12:34 GMT):

caroline-church (Wed, 07 Jun 2017 12:27:04 GMT):
@Vipul_Bajaj the acl language only allows you to either let a participant read all of an asset or none of an asset

caroline-church (Wed, 07 Jun 2017 12:29:02 GMT):
@karthikworks Can you do a docker ps please

FelixNielsen (Wed, 07 Jun 2017 12:29:55 GMT):
@caroline-church so it is not possible to define ACL where some of the fields in an asset are hidden? - like "private" keys for encrypting digital assets (binary files)

caroline-church (Wed, 07 Jun 2017 12:31:10 GMT):
no

harj91 (Wed, 07 Jun 2017 12:31:37 GMT):
@caroline-church still being given error: Error: Failed to load connector module "composer-connector-embedded" for connection profile "defaultProfile" at connectionProfileStore.load.then.e (node_modules/composer-common/lib/connectionprofilemanager.js:148:27) regardless of node and npm versions

FelixNielsen (Wed, 07 Jun 2017 12:35:44 GMT):
@caroline-church oki, but we could make another object and link to that from a given asset correct?

caroline-church (Wed, 07 Jun 2017 12:36:02 GMT):
@FelixNielsen yes

FelixNielsen (Wed, 07 Jun 2017 12:36:06 GMT):
thx!

caroline-church (Wed, 07 Jun 2017 12:37:03 GMT):
@harj91 and you didn't install using sudo? and you didn't get any errors when you installed?

hariharanatarajan (Wed, 07 Jun 2017 12:37:29 GMT):
@caroline-church I am looking at the format of the files in the crypto-config bundled with the playground install and what is present in my fabric .. Will that matter ?

sstone1 (Wed, 07 Jun 2017 12:39:32 GMT):
@hariharanatarajan we are not Fabric maintainers, if you have Fabric questions please ask them in #fabric - Composer will work with any Fabric at either v0.6 or v1.0-alpha1

hariharanatarajan (Wed, 07 Jun 2017 12:41:20 GMT):
@sstone1 Agreed . I am trying to find the value of what I should give for the AddIdentity and I am stuck there . I am assuming this should be value of the cacerts in the Orderer ? Or is it something else ?

sstone1 (Wed, 07 Jun 2017 12:42:23 GMT):
admin / adminpw is the default identity in Fabric v1.0 that allows you to deploy chaincode

sstone1 (Wed, 07 Jun 2017 12:42:23 GMT):
admin / adminpw is the default identity in Fabric v1.0-alpha1 that allows you to deploy chaincode

sstone1 (Wed, 07 Jun 2017 12:42:50 GMT):
User ID = admin, User Secret = adminpw

harj91 (Wed, 07 Jun 2017 12:43:51 GMT):
@caroline-church not sure, i am going to reinstall from the beginning

caroline-church (Wed, 07 Jun 2017 12:44:01 GMT):
@harj91 ok

hariharanatarajan (Wed, 07 Jun 2017 12:50:23 GMT):

harj91 (Wed, 07 Jun 2017 13:04:36 GMT):
@caroline-church thanks

caroline-church (Wed, 07 Jun 2017 13:04:40 GMT):
just don't install compoer as sudo

harj91 (Wed, 07 Jun 2017 13:30:03 GMT):
ok reinstalled composer without sudo, now when running npm test i get the following: Sample 1) "before each" hook for "Alice can read all of the assets" 0 passing (2s) 1 failing 1) Sample "before each" hook for "Alice can read all of the assets": Error: No chaincode ID found for business network 'basic-sample-network' at testIdentity.then (node_modules/composer-connector-embedded/lib/embeddedconnection.js:163:27)

have you deployed the business network

harj91 (Wed, 07 Jun 2017 13:35:34 GMT):
my mistake i had not updated the test/sample.js file

harj91 (Wed, 07 Jun 2017 13:35:38 GMT):
the npm test has passed now, thank you!

caroline-church (Wed, 07 Jun 2017 13:36:14 GMT):
cool, glad it now works for you :)

hariharanatarajan (Wed, 07 Jun 2017 13:51:36 GMT):
How do I make my browser / docker container forget the connections and start again ? ( short of doing a clear cache all ). I tried doing a docker-compose kill / stop . I also did a docker rmi image name and did a pull again . But the connection name seems to be remembered . I tried with a new browser ( Microsft Edge ) but that did not work at all . Any tips ?

caroline-church (Wed, 07 Jun 2017 13:53:46 GMT):
@hariharanatarajan from within playground you can click on a connection profile and delete it.

caroline-church (Wed, 07 Jun 2017 13:55:27 GMT):
@hariharanatarajan if the connection profile that you are connecting to has problems connecting and you cannot get to the connection profiles page you can clear your local storage by opening the developer console and in the console type `localStorage.clear()`

hariharanatarajan (Wed, 07 Jun 2017 13:56:59 GMT):
Thanks that's what I was looking for . The connection profile was not showing up

hariharanatarajan (Wed, 07 Jun 2017 14:01:05 GMT):
But sadly I am still stuck . I used this connection profile ```{ "name": "HariMozProfile", "description": "A description for a V1 Profile", "type": "hlfv1", "orderers": [ { "url": "grpc://orderer.example.com:7050", "cert": "", "hostnameOverride": "" } ], "channel": "harichan", "mspID": "Org1MSP", "ca": "http://ca_peerOrg1:7054", "peers": [ { "requestURL": "grpc://peer0.org1.example.com:7051", "eventURL": "grpc://peer1.org1.example.com:7053", "cert": "", "hostnameOverride": "" } ], "keyValStore": "/home/composer/.hfc-key-store", "deployWaitTime": 300, "invokeWaitTime": 30 }``` and I used an identity of admin and adminpw as the secret .. I don't see any activity in any logs

hariharanatarajan (Wed, 07 Jun 2017 14:04:22 GMT):
I opened the console in Mozilla and I see an undefined error in main.xxxxx:1043987 The previous message said loaded connection profile

tennenjl (Wed, 07 Jun 2017 14:04:36 GMT):
@hariharanatarajan Check your keyValStore

tennenjl (Wed, 07 Jun 2017 14:05:00 GMT):
it should point to your home dir

tennenjl (Wed, 07 Jun 2017 14:05:16 GMT):
which is likely diff than /home/composer

tennenjl (Wed, 07 Jun 2017 14:05:37 GMT):
so should be /.hfc-key-store

hariharanatarajan (Wed, 07 Jun 2017 14:05:52 GMT):
@tennenjl I am running playground as a docker container . So I don't know

hariharanatarajan (Wed, 07 Jun 2017 14:11:04 GMT):
@caroline-church Sadly localStorage.clear() does not work . Gives me undefined

hariharanatarajan (Wed, 07 Jun 2017 14:11:41 GMT):
@sstone1 @caroline-church can I deploy my app through APIs if possible ( without using browser ... ) .. Just checking

caroline-church (Wed, 07 Jun 2017 14:17:42 GMT):
@hariharanatarajan thats what it is supposed to do, if you know refresh the browser it should connect in web mode

caroline-church (Wed, 07 Jun 2017 14:18:22 GMT):
@hariharanatarajan yes you can deploy through the command line using `composer network deploy` command

hariharanatarajan (Wed, 07 Jun 2017 14:20:05 GMT):
Thanks @caroline-church . Would this mean I need to install the npm for API access ? Is it possible that I can do this from the docker image ?

caroline-church (Wed, 07 Jun 2017 14:21:10 GMT):
@hariharanatarajan you just do `npm install -g composer-cli` this needs to be on your local machine

caroline-church (Wed, 07 Jun 2017 14:21:46 GMT):
all the command lets you specify the connection profile and userid and secret

reginbald (Wed, 07 Jun 2017 14:24:43 GMT):
Hi has anyone gotten this error before?

reginbald (Wed, 07 Jun 2017 14:24:43 GMT):

can you paste what your model looks like

hariharanatarajan (Wed, 07 Jun 2017 14:29:42 GMT):
@caroline-church local machine/host running the docker container I guess ?

caroline-church (Wed, 07 Jun 2017 14:30:56 GMT):
@hariharanatarajan can you try a `composer network ping`

reginbald (Wed, 07 Jun 2017 14:33:30 GMT):
got it to work, the --sourceName argument had a spelling mistake :)

hariharanatarajan (Wed, 07 Jun 2017 14:34:52 GMT):
One question . I know this is not the Fabric channel but would help to know where should I look for logs ( which container ) in the fabric side

caroline-church (Wed, 07 Jun 2017 14:35:28 GMT):
@hariharanatarajan you don't need the version number in the network name

caroline-church (Wed, 07 Jun 2017 14:36:14 GMT):
if you do a docker ps and look for the id of the peer then do docker log

caroline-church (Wed, 07 Jun 2017 14:36:19 GMT):
that will show you the logs

hariharanatarajan (Wed, 07 Jun 2017 14:40:24 GMT):
ok . Even without the version number I get a slightly different stack trace ```ubuntu@hyperledger-devenv:37eb1a9:/opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli$ composer network ping -n animaltracking-network -p HariChromeProfile -i admin -s adminpw events.js:160 throw er; // Unhandled 'error' event ^ Error at ClientDuplexStream._emitStatusIfDone (/usr/local/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:189:19) at ClientDuplexStream._readsDone (/usr/local/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:158:8) at readCallback (/usr/local/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:217:12) ```

caroline-church (Wed, 07 Jun 2017 14:41:20 GMT):

hariharanatarajan (Wed, 07 Jun 2017 14:42:20 GMT):
if I do a ping ..

hariharanatarajan (Wed, 07 Jun 2017 14:42:29 GMT):
I mean composer ping

caroline-church (Wed, 07 Jun 2017 14:43:12 GMT):
ahh ok so that network isn't deployed at all so the ping is never gonig to work (sorry thats my fault)

caroline-church (Wed, 07 Jun 2017 14:43:33 GMT):
have you changed anything in the business network that you are trying to deploy

caroline-church (Wed, 07 Jun 2017 14:43:57 GMT):
can you deploy business networks from the playground?

hariharanatarajan (Wed, 07 Jun 2017 14:48:47 GMT):
From the playground ``` I get a javascript error seen in the console (in mozilla ).``` . ```In chrome the connection just hangs and no error ``` . ```Edge has error . Very pecular behavior . Not supported I guess``` . ``` Hence was looking for cli support ```

caroline-church (Wed, 07 Jun 2017 14:51:22 GMT):
@hariharanatarajan if you want to use the cli then you need to change your connection profile to use localhost

hariharanatarajan (Wed, 07 Jun 2017 14:52:47 GMT):
Oops .. that may not be possible and will not work for sure .. Just curious to see where the error is . so that we can figure out something . As of now I see no errors in console / no movement in the docker logs anywhere ..

caroline-church (Wed, 07 Jun 2017 15:10:56 GMT):
why cant you set localhost in your connection profile

Fanarito (Wed, 07 Jun 2017 15:52:09 GMT):
has anyone successfully setup passport basic auth on the rest api?

caroline-church (Wed, 07 Jun 2017 15:53:14 GMT):
Hi @Fanarito are you seeing problems?

Fanarito (Wed, 07 Jun 2017 15:54:32 GMT):
```{ "basic": { "provider": "basic", "module": "passport-http" } }``` this is the composer provider object. and I am getting this error ``` TypeError: AuthStrategy is not a constructor at PassportConfigurator.configureProvider (/usr/lib/node_modules/composer-rest-server/node_modules/loopback-component-passport/lib/passport-configurator.js:259:18) at Promise.then (/usr/lib/node_modules/composer-rest-server/server/server.js:120:38) at process._tickCallback (internal/process/next_tick.js:109:7) ```

caroline-church (Wed, 07 Jun 2017 15:59:19 GMT):
@Fanarito can you run the command `set | grep cpmposer`

Fanarito (Wed, 07 Jun 2017 16:01:36 GMT):
`set | grep -i composer` returns `Binary file (standard input) matches`

Fanarito (Wed, 07 Jun 2017 16:02:34 GMT):
`echo $COMPOSER_PROVIDERS` returns ```{ "basic": { "provider": "basic", "module": "passport-http" } }```

caroline-church (Wed, 07 Jun 2017 16:11:08 GMT):
can you use the rest server without authentication?

Fanarito (Wed, 07 Jun 2017 16:11:21 GMT):
@caroline-church yup

Fanarito (Wed, 07 Jun 2017 16:13:19 GMT):
`composer-rest-server -p defaultProfile -n animal-network -i admin -s adminpw -S true` this is the command I use to run the server

caroline-church (Wed, 07 Jun 2017 16:21:48 GMT):
@Fanarito i think it might be your configuration that is wrong, we have only tested a couple of passport strategies and it might require alot of investigation and testing on your part. Why don't you try using the github passport in these instructions https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html to get you going and then maybe change to your preferred passport later

caroline-church (Wed, 07 Jun 2017 16:23:01 GMT):
@Fanarito THis is the example we followed for the rest server https://github.com/strongloop/loopback-example-passport it might give you more info

Fanarito (Wed, 07 Jun 2017 16:40:14 GMT):
@caroline-church alright, thanks for the help.

gauthampamu (Wed, 07 Jun 2017 19:24:06 GMT):
I have some questions on securing the REST endpoint. https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html It explains that you can add identities to the Wallet but it is not clear how it will provide private wallet for each client. Its explains how you can add identities to the wallet but it is not clear how or when you would add the identity. Is this article just explaining how to add security so that only authenticated users in the case of the article with github users to process the request and you are changing the identity used by the rest endpoint after it is started by using the REST API to change the default identity.

@gauthampamu each authenticated user gets their own private wallet. only an authenticated user can access a wallet, and an authenticated user can only access their wallet.

sstone1 (Wed, 07 Jun 2017 19:33:52 GMT):
in order for an authenticated user to make a request to the blockchain, they must add an identity to their wallet.

gauthampamu (Wed, 07 Jun 2017 19:34:09 GMT):
ok

gauthampamu (Wed, 07 Jun 2017 19:34:38 GMT):
Because they use it..they have to add the identity to the wallet.

gauthampamu (Wed, 07 Jun 2017 19:34:48 GMT):
I meant before they use it.. .

sstone1 (Wed, 07 Jun 2017 19:34:52 GMT):
correct

sstone1 (Wed, 07 Jun 2017 19:35:46 GMT):
all of the identities (enrollment ID, secret, certificate) are stored in the wallet by the REST server; that data is persisted in the specified data source (the docs use mongo as an example)

gauthampamu (Wed, 07 Jun 2017 19:37:46 GMT):
If you are using the REST endpoint from the nodejs application. How would you authenticate with it, can you pass the credentials. Lets say the web application is configured with oauth and it using the bluemix sso service.

gauthampamu (Wed, 07 Jun 2017 19:39:34 GMT):
It would be helpful if you can share a sample web application that connects to the secure REST endpoint. Slight variation of the existing sample. https://hyperledger.github.io/composer/applications/subscribing-to-events.html

gauthampamu (Wed, 07 Jun 2017 19:39:45 GMT):
I meant....

gauthampamu (Wed, 07 Jun 2017 19:40:05 GMT):
https://hyperledger.github.io/composer/tutorials/developer-guide.html

sstone1 (Wed, 07 Jun 2017 19:42:32 GMT):
yeah, we don't have one of those yet... am thinking about it

sstone1 (Wed, 07 Jun 2017 19:42:36 GMT):
there is an API key

sstone1 (Wed, 07 Jun 2017 19:42:38 GMT):
you can't see it

sstone1 (Wed, 07 Jun 2017 19:42:54 GMT):
but when you go through the OAuth flow it creates one and sticks it into a cookie in your web browser

sstone1 (Wed, 07 Jun 2017 19:43:03 GMT):
we need to expose that and make it discoverable

sstone1 (Wed, 07 Jun 2017 19:43:31 GMT):
you can then use it to make REST calls... http://localhost:3000/api/Cars?auth_token=VERY_LONG_ID

sstone1 (Wed, 07 Jun 2017 19:44:04 GMT):
however if you're building a web application, you can just do the OAuth stuff in the browser and then call the REST API from the web browser

sstone1 (Wed, 07 Jun 2017 19:44:13 GMT):
but understand people will want/need that middle tier Node.js app

gauthampamu (Wed, 07 Jun 2017 19:47:04 GMT):
Also to the current rest endpoint server, it is possible to add additional API to that list.

sstone1 (Wed, 07 Jun 2017 19:56:33 GMT):
not with the Composer REST server

sstone1 (Wed, 07 Jun 2017 19:56:44 GMT):
the Composer REST server is just a LoopBack application though

sstone1 (Wed, 07 Jun 2017 19:57:03 GMT):
you can take the Composer LoopBack connector and boot scripts and put them into your own LoopBack application, and add additional APIs into that

torresjeff (Wed, 07 Jun 2017 20:24:10 GMT):
@sstone1 will this example work with HLFv1 on Bluemix? https://github.com/sstone1/sample-bluemix-composer-app

torresjeff (Wed, 07 Jun 2017 20:24:46 GMT):
tried using the object storage service (it worked fine with v0.6), but now I'm getting this error: `Error: Private key missing from key store. Can not establish the signing identity for user admin`

torresjeff (Wed, 07 Jun 2017 20:25:15 GMT):
i uploaded the three files composer generates when trying to deploy a network (-priv, -pub and admin)

sstone1 (Wed, 07 Jun 2017 20:25:21 GMT):
judging by the manifest i think i only tried it on a v0.6

sstone1 (Wed, 07 Jun 2017 20:25:31 GMT):
you uploaded the files into the object store service?

torresjeff (Wed, 07 Jun 2017 20:25:35 GMT):
yeah

sstone1 (Wed, 07 Jun 2017 20:25:58 GMT):
i know someone was having a problem with HLFv1 and the persistent wallet (MongoDB)... i haven't yet investigated it

torresjeff (Wed, 07 Jun 2017 20:26:38 GMT):
is there a temporary solution for this?

sstone1 (Wed, 07 Jun 2017 20:28:40 GMT):
nope

sstone1 (Wed, 07 Jun 2017 20:28:43 GMT):
not that i know of

torresjeff (Wed, 07 Jun 2017 20:31:51 GMT):
@sstone1 question regarding hlfv1, unlike v0.6 now the CAs are not limited to issuing the certificates only once?

sstone1 (Wed, 07 Jun 2017 20:33:38 GMT):
i think the number of times the cert can be issued is controllable

sstone1 (Wed, 07 Jun 2017 20:33:47 GMT):
for the admin cert, it seems to be "unlimited"

sstone1 (Wed, 07 Jun 2017 20:34:10 GMT):
but the admin cert is changing in alpha2/alpha3/beta1 - there's no more enrolment process for it, you have to get the cert files from your fabric administrator

opiepj (Wed, 07 Jun 2017 20:34:58 GMT):
Maybe a dumb question, but what's the point of using enums in our model if my APIs enforce me to return strings anyways

dselman (Wed, 07 Jun 2017 20:34:59 GMT):
(out of band)...

dselman (Wed, 07 Jun 2017 20:35:33 GMT):
@opiepj the validator will check that the string value corresponds to one of your enums.

torresjeff (Wed, 07 Jun 2017 20:35:49 GMT):
ok, thanks!

opiepj (Wed, 07 Jun 2017 20:36:08 GMT):
Can it accept integers as well?

opiepj (Wed, 07 Jun 2017 20:36:13 GMT):
that reflect the enum

dselman (Wed, 07 Jun 2017 20:36:16 GMT):
no

opiepj (Wed, 07 Jun 2017 20:36:34 GMT):
since I'm building out my forms to the specs of the generated interfaces

dselman (Wed, 07 Jun 2017 20:39:07 GMT):
If you are building forms from the model I'd strongly encourage you to use the visitor pattern (we have lots of example model visitors) rather than for loops to build your forms. This will make the form generation more robust to new types in the future.

opiepj (Wed, 07 Jun 2017 20:39:52 GMT):
Do you have a link?

dselman (Wed, 07 Jun 2017 20:40:06 GMT):
yes, one sec

opiepj (Wed, 07 Jun 2017 20:42:20 GMT):

dselman (Wed, 07 Jun 2017 20:42:22 GMT):
How to visit: https://github.com/hyperledger/composer/blob/master/packages/composer-cli/lib/cmds/generator/lib/createCode.js

opiepj (Wed, 07 Jun 2017 20:43:00 GMT):
ah

dselman (Wed, 07 Jun 2017 20:43:45 GMT):
Most (all?) model elements are visitable... so you can call `accept` on a BusinessNetworkDefintion, a ModelManager, a ClassDeclaration etc.

opiepj (Wed, 07 Jun 2017 20:44:15 GMT):
Okay so if I run this class it will generate my models based on my .bna

opiepj (Wed, 07 Jun 2017 20:44:16 GMT):
?

dselman (Wed, 07 Jun 2017 20:45:27 GMT):
You could implement an HTMLFormVisitor which generates HTML markup by visiting the model elements (you just implement the visitor). You would store the markup you generate in the `parameters` for the visitor.

opiepj (Wed, 07 Jun 2017 20:45:29 GMT):
All I'm seeing is `new TypescriptVisitor();`

dselman (Wed, 07 Jun 2017 20:46:00 GMT):
Yes, we have visitors for type script, UML, Go, JSON schema, etc. etc.

dselman (Wed, 07 Jun 2017 20:47:25 GMT):
... we should move this to #composer-dev

torresjeff (Wed, 07 Jun 2017 21:02:19 GMT):
@sstone1 @dselman what is the new container that gets created when deploying a business network

torresjeff (Wed, 07 Jun 2017 21:02:24 GMT):
would that be a channel?

sstone1 (Wed, 07 Jun 2017 21:02:42 GMT):
it's the chaincode

torresjeff (Wed, 07 Jun 2017 21:02:44 GMT):
i can't seem to stop it

torresjeff (Wed, 07 Jun 2017 21:03:07 GMT):
that didn't happen with hlfv0.6 right?

sstone1 (Wed, 07 Jun 2017 21:06:49 GMT):
if you stop it

sstone1 (Wed, 07 Jun 2017 21:06:55 GMT):
and then call the chaincode

sstone1 (Wed, 07 Jun 2017 21:07:00 GMT):
i think the peer will start it again

gauthampamu (Wed, 07 Jun 2017 21:26:29 GMT):
@sstone1 How is the ACL implemented in the composer runtime. Is it done as it is implemented in the golang code in carlease sample application.

sstone1 (Wed, 07 Jun 2017 21:29:52 GMT):
it uses encrypted attributes in v0.6 and the common name in the ecert in v1.0 to identify the current user, and we use that to look up a participant in a participant registry

sstone1 (Wed, 07 Jun 2017 21:30:01 GMT):
that participant is the "current participant"

sstone1 (Wed, 07 Jun 2017 21:30:09 GMT):
all ACLs act on the "current participant"

AccentSandy (Wed, 07 Jun 2017 22:01:42 GMT):

jdockter (Wed, 07 Jun 2017 23:18:29 GMT):
@here wondering what the community has done or development team @sstone1 @dselman @caroline-church @davidkel around the initial creation of participant instances and issuing of corresponding identities for a deployed business network...is the expectation there will be some sort of bootstrapped config or transaction that will preload participants...or will that be the responsibility of an admin / regulator to do this AFTER the network is deployed...or something all together different??? The docs talk about an existing participant (https://hyperledger.github.io/composer/managing/participantsandidentities.html) but how did that existing participant get loaded into the network? SO question posted as well - https://stackoverflow.com/questions/44424240/preloading-participant-instances-and-issuing-corresponding-identities

mattalhonte (Thu, 08 Jun 2017 03:44:22 GMT):
Made an Angular app, it can't find the REST server for some reason. Just says "Error: Could not connect to REST server. Please check your configuration details". I can query it from my browser and curl, though

rama_rahul (Thu, 08 Jun 2017 05:10:03 GMT):
For example if I want any transaction to occur automatically without me submitting it (i.e if we take car-auction instance, I want to closebidding after 4 days of starting it). Is it possible in composer?

dselman (Thu, 08 Jun 2017 05:43:23 GMT):
@jdockter we are tracking that requirement under this issue: https://github.com/hyperledger/composer/issues/670

dselman (Thu, 08 Jun 2017 05:43:53 GMT):
We've not made much progress on that yet, but it is clearly necessary.

dselman (Thu, 08 Jun 2017 05:45:21 GMT):
If you have requirements, or thoughts on how to be implement, please add to the issue

dselman (Thu, 08 Jun 2017 05:48:42 GMT):
@rama_rahul blockchains and time-based logic are uncomfortable bed-fellows, due to the need for determinism. However, it would be possible/easy to use an external "cron" process (Node-RED and OpenWhisk both have time-based triggers) to automatically submit a transaction to Composer.

rama_rahul (Thu, 08 Jun 2017 05:57:34 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=eFeekCXpBodKE4m86) @dselman Can you send a link for getting started with this?

dselman (Thu, 08 Jun 2017 05:58:45 GMT):
The easiest way to prototype this would be to use the Node-RED node that @caroline-church created: https://www.npmjs.com/package/node-red-contrib-composer

dselman (Thu, 08 Jun 2017 05:59:06 GMT):
Install Node-RED: https://nodered.org

dselman (Thu, 08 Jun 2017 06:00:08 GMT):
Then add the Composer Node and create a flow that includes an injection node: http://nodered.org/docs/getting-started/first-flow

dselman (Thu, 08 Jun 2017 06:00:35 GMT):
The injection node can create the JSON for a transaction, passing it to the Composer node for submission to Composer.

dselman (Thu, 08 Jun 2017 06:01:35 GMT):
Please share your results -- I'm sure lots of people would be interested to see that.

deepakvparmar (Thu, 08 Jun 2017 06:07:35 GMT):
@dselman : By default, composer-rest-server is providing CRUD REST API for Asset and Participants. If I would like to fetch selective Asset and Participants, then do i need to write Transaction or is there any way we can add REST API into composer-rest-server itself?

dselman (Thu, 08 Jun 2017 06:08:03 GMT):
What do you mean by selective?

deepakvparmar (Thu, 08 Jun 2017 06:09:01 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=bHeJLML4yb6Z5NWaL) @dselman : For example, I would like to fetch Asset based on other query parameter such as asset type or asset status. Currently, I can only fetch asset by assetId only.

dselman (Thu, 08 Jun 2017 06:10:01 GMT):
We are working on adding support for complex (content-based) queries. It requires using HLF v1 with CouchDB for the world-state storage.

dselman (Thu, 08 Jun 2017 06:10:14 GMT):
Ultimately those queries will be exposed over REST

dselman (Thu, 08 Jun 2017 06:11:02 GMT):
So, I don't think you'll be able to run those queries efficiently without the underlying support for complex queries.

akshay111meher (Thu, 08 Jun 2017 06:14:07 GMT):
@davidkel @clueless99 @sstone1 thanks for the help... solved the issue with composer-transactions... We basically had to annotate each transaction in the .js file... which i was unaware of... also by declaring the transactions seperately in each .js file, this is solved.... another which we encoutering is in the transaction, i am trying to get the identifier, it is returning null.. basically,, var currentParticipant = getCurrentParticipant(); var identifier = currentParticipant.getFullyQualifiedIdentifier(); this gives a error saying *cannot read property 'getFullyQualifiedIdentifier' of null*

dselman (Thu, 08 Jun 2017 06:16:25 GMT):
`getCurrentParticipant()` will only be non-null if an identity has been issued (associated) with the certificate that you use to submit the transaction. My guess is that you are using a generic Fabric cert (admin?) for which no Composer participant association exists. https://hyperledger.github.io/composer/unstable/reference/composer.identity.issue.html

[ ](https://chat.hyperledger.org/channel/composer?msg=hAMgj6nYAQD49ra4K) @dselman : Thank You dan. I think, I have only one option for now to fetch world-state data based on content query is to fetch all asset or participants and then filter out required data?

dselman (Thu, 08 Jun 2017 06:16:43 GMT):
Correct

dselman (Thu, 08 Jun 2017 06:17:42 GMT):
We're working as fast as we can to get complex queries in, as this is clearly unacceptable for production applications.

dselman (Thu, 08 Jun 2017 06:26:05 GMT):
You simply create a new business network connection logging in using maeid1 as the userid - if you use this connection to submit a transaction it will use the ECert that was issues by the call to issueIdentity. This ECert has metadata on it that associates it with net.biz.digitalPropertyNetwork.Person#mae

dselman (Thu, 08 Jun 2017 06:26:48 GMT):
you can test this using `composer network ping`

dselman (Thu, 08 Jun 2017 07:32:34 GMT):
correct

dselman (Thu, 08 Jun 2017 07:33:17 GMT):
seems like your connection profile or runtime is not configured correctly. How did you create them?

davidkel (Thu, 08 Jun 2017 07:44:43 GMT):
@akshay111meher issue identity doesn't create the files in the keystore, that will only occur when you enroll that newly created identity. However it looks like the enrollment failed due to authorisation failure. You could try looking in the logs of the ca to see what error it output, but I suspect it won't give anything useful. Could you recheck your secret just to make sure it's correct

There's no point moving onto code until: 1. composer network ping works with your admin id. 2/ You can issue an identity correctly with the command line. 3/ You can ping with your new id correctly

Along with other stuff to get it running. The network runs fine and I've just written a function in `logic.js` to transfer ownership of an asset in the network. My question is about peer validation. Is there a specific way I have to write (in the `logic.js` file) peer validation for the transactions I've made. Or is it done automatically by the network? My connection profile specifies two peers, as is the default for a hlfv1 connection profile I believe. So do I have to write any specific code to validate with both these peers or is it handled in the background? I hope thats clear!

dselman (Thu, 08 Jun 2017 09:34:44 GMT):
It is automatic -- the Fabric will take care of ensuring that both peers run your logic and will check that the side-effects are the same on both peers (consensus). If the side-effects are the same, then the transaction is committed.

AlexJYoungman (Thu, 08 Jun 2017 09:35:39 GMT):
@dselman Awesome thanks! I wondered why I couldn't find any examples anywhere

AlexJYoungman (Thu, 08 Jun 2017 09:40:06 GMT):
Is there any way to view the peer validation? Such as a command line output or log file? (Working for stakeholders who will ideally want to see some proof the validation is taking place)

deepakvparmar (Thu, 08 Jun 2017 09:42:55 GMT):
@dselman : Just replied to your comment on SO as : True, but I had only created participant and haven't issued identity. then how come CA is giving error that user is already registered? If user is already registered, then how can i get secret for the registered user then?

Hi @caroline-church I have lowered the npm version to 3.10.10 as its recommended in the documentation and i am following the installation guide mentioned here https://hyperledger.github.io/composer/getting-started/development-tools.html I am trying to setup the hyper ledger instance and deploy the prototype network but getting same error. Error: Failed to load connector module "composer-connector-hlfv1" for connection profile "hlfv1" Command failed I have also looked on stack overflow answer listed here regarding the same issue https://stackoverflow.com/questions/44374331/hyperledger-composer-failed-to-load-connector-module-composer-connector-hlfv1 but the solution suggesting uninstallation and reinstallation of docker didn’t work either. Can you please guide me in the right direction? Thanks

Hi @Fanarito Can you show me your acl rules and your model file

genecyber (Thu, 08 Jun 2017 15:28:12 GMT):
I'm having fabric rest fall over and would love to understand testing, or patterns, or others who have worked around this type of issue

jwende (Thu, 08 Jun 2017 15:29:19 GMT):
@davidkel I run the linux image in VmWare workstation and I updated the base image using the script from the composer help page

sstone1 (Thu, 08 Jun 2017 15:34:02 GMT):
@genecyber @pascallouis we haven't done a whole lot of performance testing yet... it's still early days on that front

sstone1 (Thu, 08 Jun 2017 15:34:07 GMT):
this error however is familiar `Error: started twice without stopping`

sstone1 (Thu, 08 Jun 2017 15:34:20 GMT):
it's a bug in the Node.js SDK for Fabric v0.6

sstone1 (Thu, 08 Jun 2017 15:34:26 GMT):
i believe it is fixed for Fabric v1.0

genecyber (Thu, 08 Jun 2017 15:34:34 GMT):
ok good to know thanks

genecyber (Thu, 08 Jun 2017 15:35:00 GMT):
sounds like a race

genecyber (Thu, 08 Jun 2017 15:35:40 GMT):
If I wanted to bypass the REST interface and talk directly to fabric, how difficult would it be to set up?

davidkel (Thu, 08 Jun 2017 15:35:50 GMT):
@jwende I'm at a loss to the problem, all I can suggest is rebooting the vm and trying again.

jwende (Thu, 08 Jun 2017 15:36:18 GMT):
@davidkel thx - will try

jwende (Thu, 08 Jun 2017 15:36:32 GMT):
even if it not a windows system :-D

sstone1 (Thu, 08 Jun 2017 15:36:41 GMT):
@genecyber not sure what you mean; the Composer REST server uses the Composer Node.js APIs, which in turn use the Fabric Node.js APIs to communicate with the Fabric over gRPC

JohnWhitton (Thu, 08 Jun 2017 15:47:53 GMT):
@sstone1 and team, is there a composer call again today - I'm sorry I didn't save the link for the call in

@jwende I'm out of ideas sorry. It sounds like a docker networking problem, and I haven't encountered it before where everything looks as though it has set up correctly. I also run 16.04 but in virtualbox. I haven't tried vmware virtualisation

sstone1 (Thu, 08 Jun 2017 15:54:26 GMT):

@torresjeff we are working on v2 of that (called vehicle-lifecycle-demo) -- hope to release that into Open Source for the release next Thurs.

vinitesh (Thu, 08 Jun 2017 17:07:09 GMT):
We are creating 2 channels (C1 and C2). On C1 we have 3 members(A,B and D) and on C2 we have 2 members (A and D). member A should have access to all assets in C1 and C2. I have deployed network on both C1 and C2 .There is one asset type on the Network. T1 asset instance is created on C1 and should then be available on C2 for certain changes . Q1) how does T1 get manifested in C2 without being created again ?

@lbennett Composer TP functions are restricted to using ES5 JavaScript, which does not have `const`.

Does the latest version of Composer support creation of multiple channels? If so, can someone point to some document on the same? Thanks in advance

davidkel (Fri, 09 Jun 2017 10:20:38 GMT):
@SanketPanchamia Composer doesn't provide any operational facilities for fabric and no plan to do so, it expects the fabric to be set up and configured already as required. You might want to try the hyperledger fabric documentation to look at how to set up your own specific fabric environment.

What is the relationship between assets created in a composer network to the assets in fabric chaincode?

davidkel (Fri, 09 Jun 2017 11:23:48 GMT):
@MeenakshiSingh can you provide some info about your environment please. OS version, node version, npm version, docker version, amount of memory your machine has ?

Fanarito (Fri, 09 Jun 2017 13:24:44 GMT):
there seems to be a bug in either the composer rest connector or the composer client registry. When I try to resolve relationships using the rest api it resolves relationships that are not arrays fine, but when it tries to resolve relationships that are arrays it returns the string `"[object Object]"`

Fanarito (Fri, 09 Jun 2017 13:26:12 GMT):
the weird thing is though, that it only returns `"[object Object]"` on top level relationships, it works fine when there are multiple levels of relationships

MeenakshiSingh (Fri, 09 Jun 2017 13:34:29 GMT):
@davidkel Yes..sure. My OS is Ubuntu 16.04 LTS, node version: 6.10.3 npm version: 3.10.0 Docker version 17.03.1-ce, build c6d412e and I am running this on a t2 micro instance on AWS (1 vCPU and 1GiB memory)

davidkel (Fri, 09 Jun 2017 13:43:40 GMT):
@MeenakshiSingh sorry, you need more memory you need 4Gb to run composer and a local hyperledger fabric

MeenakshiSingh (Fri, 09 Jun 2017 13:44:54 GMT):

When running "npm test" on the tutorial part "Write Unit Tests", I come across the error (mentioned previously) of "The keyword 'const' is reserved". I looked into the ECMA version and it is 2015. Threads on StackOverflow say to run ECMA version 6. I have tried to replace that value to 6, 7, and 8 as well as 2015, 2016, and 2017. And I still get that error.

Hi, I am looking at the REST POST (Add new Entity) operation response content and it looks like the following:

uber.twin (Fri, 09 Jun 2017 14:59:47 GMT):
``{ "$class": "my.Party", "identifier": [ null, null ], "status": "Active", }``

uber.twin (Fri, 09 Jun 2017 14:59:47 GMT):
```{ "$class": "my.Party", "identifier": [ null, null ], "status": "Active", }```

what would be the reason to have a an array with null values ([null,null]) associated with the identifier field?

uber.twin (Fri, 09 Jun 2017 15:01:28 GMT):
the "identifier" field is a String type

@mlau7 or change the eslint rule to allow `const`

given that this is a unit test (which won't run on Fabric) that will work

dselman (Fri, 09 Jun 2017 15:57:33 GMT):

davidkel (Fri, 09 Jun 2017 17:06:43 GMT):
@dwakeman there is a timeout in fabric such that if the chaincode doesn't respond in a certain amount of time it fails. Deploying a business network requires chaincode to run an initialisation process. This taking longer than the peer allows for could be the problem although given you are trying to do this in a kubenetes environment it could be something else. There is an environment variable that can control the timeout 'CORE_CHAINCODE_EXECUTETIMEOUT' in milliseconds which you could set. The default if it isn't set is 30000ms

The magic happens in the `composer-runtime-hlfv1` package

@dselman running docker toolbox -- and the containers are listening on the specified ports

davidkel (Fri, 09 Jun 2017 18:50:46 GMT):
@theophoric docker toolbox is the legacy docker implementation for mac, they also have docker for mac which may work better. I believe that's what other people use, but not sure.

dwakeman (Fri, 09 Jun 2017 20:46:53 GMT):
@davidkel Thanks for the info about the timeout environment variable. I updated my kube config file for org1peer1 to include that variable, but it didn't seem to make any difference. I captured the logs from org1peer1, starting right before I submitted the composer network deploy command, and ending right after it timed out. I will upload it. In looking through it, I could swear that all of the [chaincode] entries make it look like things worked, but the command still hangs, and times out later. in the logs there is something about "context canceled". Ideas? I am using composer 0.7.5 and fabric alpha1. My log file is called biznetworkdeployfailed.log. Thx!

davidkel (Fri, 09 Jun 2017 21:02:06 GMT):
@dwakeman guess you set the timeout for 5 minutes ? should have started by then, so not sure what the problem is but for whatever reason the chaincode container maybe isn't communicating back to the peer

dwakeman (Fri, 09 Jun 2017 21:03:36 GMT):
yep, 5 min. I was digging through the entire peer log and found this: `[36m2017-06-09 19:56:01.678 UTC [chaincode] NewChaincodeSupport -> DEBU 01c[0m Setting execute timeout value to 300000 ms`

dwakeman (Fri, 09 Jun 2017 21:04:32 GMT):
perhaps I will install playground locally and see if the problem occurs there.

davidkel (Fri, 09 Jun 2017 21:06:42 GMT):
@dwakeman just out of interest are you using minikube ? Something I was going to play with sometime just never had the time

dwakeman (Fri, 09 Jun 2017 21:08:23 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Qm9QACQByPWu4i42a) @davidkel I have minikube installed on my mac, but no, this is in bluemix. I see this in the log: ```[36m2017-06-09 20:16:32.581 UTC [ccprovider] NewCCContext -> DEBU 1020[0m NewCCCC (chain=channel1,chaincode=pharma-network,version=0.7.5,txid=6c24bd3d2f9394f226b15af2d9072746443356edab83f403ed5832dfc689d926,syscc=false,proposal=0xc421acbd10,canname=pharma-network:0.7.5 [36m2017-06-09 20:16:32.600 UTC [chaincode] launchAndWaitForRegister -> DEBU 1024[0m start container: pharma-network:0.7.5(networkid:nid1,peerid:jdoe) CORE_CHAINCODE_ID_NAME=pharma-network:0.7.5``` I'm guessing that means it launches the chaincode container and waits for it to callback to the peer to register. When that doesn't happen in the timeout period the deploy command fails. Is that relatively close?

davidkel (Fri, 09 Jun 2017 21:10:11 GMT):
@dwakeman another cause of that is that the chaincode container dies unexpectedly. For example if it runs out of memory. You would need to get someone in bluemix to help you if determine if that is the case.

Guys, if anyone is interested, I've tried to deploy vehicle-lifecycle-network sample to Bluemix's v.0.6 service and it didn't work. Considering that just before that I successfully deployed basic-sample-network sample, it seems like there is a problem with deploying large networks. Suspect timeouts to be the cause.

davidkel (Sat, 10 Jun 2017 07:28:22 GMT):
@nvlasov Looks like it got changed recently, many thanks I will raise an issue for the docs to get it changed.

You can use `yo` to generate an Angular app from a business network definition. The generated code calls the `composer-rest-server`.

@StephaneMery Support for setting grpc message sizes is coming when we support the beta fabric drop (which hopefully will be this coming week), although you won't be able to set these using playground directly, you will be able to set them directly in the connection profile and you should be able to import that into playground if necessary

dselman (Sun, 11 Jun 2017 15:42:56 GMT):
No, you should not need to update the scripts. Composer 0.7.5 supports Alpha1. You could try `export DEBUG=*` and rerunning, it may give you more detail. What do you see if you run `docker ps -a`?

You probably just need to reinstall `node-red-contrib-composer` -- its `package.json` is set to pickup the latest version of `composer-client`

@sachaLiguori That's one I have never seen before. Looks like docker itself had a problem. I do know there is a 17.03.1 version of docker `Docker version 17.03.1-ce, build c6d412e` if you aren't at that level try upgrading

@sachaLiguori well it's definitely a problem with docker. a quick search shows that other people have had similar problems but no obvious cause or resolution.

@sachaLiguori Sorry can't offer any more suggestions. It's a problem with docker and in order to perhaps understand more you would need to actually debug docker itself.

what updates are necessary in order to get the changes?

@uber.twin I got that exact same message in Composer 0.7.5 versus it not being a problem in 0.7.4- by simply doing the *npm install* from the composer-sample-application-hlfv1 github repo... now this package has moved from hyperledger to hyperledger-archives on GitHub and I don't see it in the 'official' docs now so I don't know if it is supported any longer. But I am very interested in a workaround- don't have a solution yet- in fact was just about to post here to inquire about it when your message appeared

silliman (Mon, 12 Jun 2017 14:37:24 GMT):
@uber.twin I have to run to an appointment and so will be out of pocket for a couple hours but will check in and happy to provide more details when I get back...but your stack trace is exactly what I got when running the npm install instead the packages/getting-started directory from composer-sample-applications-hlfv1 ... worked fine in Composer 0.7.4 (and earlier)

uber.twin (Mon, 12 Jun 2017 14:46:18 GMT):
@silliman alright, thank you. I am also developing in the context of the composer-sample-applications-hlfv1 environment. Didn't do any kind of update to it, I only updated the global composer-cli and composer-rest-server packages

I'd like to call everyone's attention to https://jira.hyperledger.org/browse/FAB-4563, it's not an issue of immediate concern *in my opinion* but if anyone thinks we are making the wrong assumptions for the current SDK's stateful design, please speak up.

@CT123 have you run `npm install` in the getting-started directory ? The test file default.js has tried to load a node module called `chai` but node cannot find it anywhere in it's node path. npm is the tool that is used to download node modules and it looks in the file 'package.json' in the getting-started directory which will declare the dependency on 'chai'

sstone1 (Mon, 12 Jun 2017 20:24:48 GMT):
Yeah, if you cleared up your Fabric environment you should configure it as per: https://hyperledger.github.io/composer/installing/development-tools.html

sstone1 (Mon, 12 Jun 2017 20:25:33 GMT):
@dwakeman it's probably looking for the `hyperledger/fabric-ccenv` image

dwakeman (Mon, 12 Jun 2017 20:31:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=F4MPRoDsseX5Yq839) @sstone1 Thx! Is that specified somewhere in a config file I would have control over, or is it buried in the code? I would have expected it to pull the image if it wasn't already available. I did see some sort of error report about a bug that might be related to this.

sstone1 (Mon, 12 Jun 2017 20:31:43 GMT):
It's a Fabric thing - the Fabric controls which base image is used for building chaincode containers

sstone1 (Mon, 12 Jun 2017 20:32:05 GMT):
It's done using Docker tags - the ccenv image must match the tag of the peer image

sstone1 (Mon, 12 Jun 2017 20:32:36 GMT):
e.g. here's alpha1: ``` hyperledger/fabric-peer x86_64-1.0.0-alpha 784c5d41ac1d 2 months ago 184 MB hyperledger/fabric-ccenv x86_64-1.0.0-alpha 91792014b61f 2 months ago 1.29 GB ``` and here's alpha2: ``` hyperledger/fabric-ccenv x86_64-1.0.0-alpha2 c984ae2a1936 4 weeks ago 1.29 GB hyperledger/fabric-peer x86_64-1.0.0-alpha2 23b4aedef57f 4 weeks ago 185 MB ```

dwakeman (Mon, 12 Jun 2017 20:33:50 GMT):
ok. It works locally on my machine, but not in minikube, where I am playing around with kubernetes. I must have done something wrong in there. Okay, thx for the info!

Tigermisu (Mon, 12 Jun 2017 20:38:36 GMT):

you need to write a Node.js client application using the `composer-client` module from npm

davidkel (Mon, 12 Jun 2017 21:33:57 GMT):
@CT123 Just noticed that node and npm were installed in /usr/local/bin. This will cause problems as node modules will try to install into directories that only root has write access to which means you have to use sudo and npm doesn't behave well by default under sudo. You should install node under your standard login user, rather than installing it using sudo.

sorry if this is a repeat...can we limit what resources are exposed via the REST server and thus to what is generated as a swagger document?

Any reason on why the `yo hyperledger-composer` command gets stuck attempting to connect? ``` ? Do you want to generate a new REST API or connect to an existing REST API?: G enerate a new REST API ? What port number should the generated REST server run on?: 3000 ? Should namespaces be used in the generated REST API: Never use namespaces About to connect to a running business network ``` It's been there for a while.

dwakeman (Tue, 13 Jun 2017 03:03:00 GMT):
question about writing a node.js app to connect to fabric..... In the documentation it looks like you specify the name of a connection profile that would presumably be found in the .composer-connection-profiles directory on the machine running the node.js app. Can I skip that and just provide the JSON that is in connection.json directly in my node.js app, as opposed to relying on a file on the filesystem?

dselman (Tue, 13 Jun 2017 07:02:04 GMT):
No, but you can configure Node to use an in-memory file system -- that is what the unit tests do. E.g. https://github.com/hyperledger/composer-sample-networks/blob/master/packages/bond-network/test/Bond.js

dselman (Tue, 13 Jun 2017 07:02:27 GMT):
You can also set an environment variable that contains your connection profile.

dselman (Tue, 13 Jun 2017 07:05:25 GMT):

Is there any way to persist network data? So when I run the Fabric on Docker and deploy a network and make changes (create assets etc) and then stop the fabric running I lose all the data that was stored. Obviously this isn't ideal for use on a server, if theres any outages we would lose all our information. (apologies if this is the wrong channel)

dselman (Tue, 13 Jun 2017 09:29:42 GMT):
That is an operational concern and falls outside the scope of Composer -- at least as it stands. Fabric is replicating data across peer and storing it on disk, so it is crash-fault-tolerant.

@sstone1 Creating and managing Fabric networks, its something doable ?

sstone1 (Tue, 13 Jun 2017 11:23:51 GMT):
Yes, but it is not a Composer problem, it is a Fabric problem. You need to use the Fabric documentation and tools to create and manage a Fabric network.

@Binay1 you first need to deploy a Fabric Blockchain network across the network of computers. You can then deploy the Composer application to that Fabric Blockchain network. Composer does not include any tools for deploying Fabric Blockchain networks - for that, you need to consult the Fabric documentation.

I suspect, based on our private conversation yesterday, that there are env varables or other setup steps necessary for beta that aren't in the docker-compose.yml and scripts in composer-sample-applications-hlfv1, and never will be, so that now is the time to switch to composer-sample-applications along with the fabric setup that is in the composer-tools repo? Am I right?

dwakeman (Tue, 13 Jun 2017 17:41:58 GMT):
@hariharanatarajan if you are talking about changing the namespace to something other than `org.acme.sample`, and renaming the files to match, then you can export the archive from the playground, rename it to a zip file, extract it to a folder and use vscode to do all of that. When you're done, use the composer archive command to recreate a BNA file that you can import back into composer playground. There may be a better way, but that's what I've done with my demos.

torresjeff (Tue, 13 Jun 2017 18:22:41 GMT):

@torresjeff not yet, but the historian will add this functionality

sstone1 (Tue, 13 Jun 2017 18:32:01 GMT):
until then - you need to add a `participant` property and set it using `getCurrentParticipant()`

torresjeff (Tue, 13 Jun 2017 18:32:30 GMT):
so should i call `getCurrentParticipant()` from the TP function?

Is there a way I could 'log' a value to console produced by a transaction in the Composer Playground, or otherwise see the result of a function called inside the transaction?

Tigermisu (Tue, 13 Jun 2017 22:22:16 GMT):
Also, I have a question regarding the inner working of a blockchain. If I have a function that returns a random number `Math.random()` , how is it that this function returns the same number in every peer that executes it? (It is my understanding that every peer much reach consensus) Same about other contextual functions, i.e. `new Date().getTime()`

dklesev (Tue, 13 Jun 2017 22:51:09 GMT):
@Tigermisu just use console.log('this will be printed to console') if you use random values you will unlikely get consensus between your peers. better solution is to use random values outside of transaction logic (because every transaction has to be deterministic)

Tigermisu (Tue, 13 Jun 2017 22:54:19 GMT):
Oh, I see. I thought it was handled internally somehow.

Has anybody worked with the node red nodes to subscribe to events emitted from my transaction processor functions? I tried to add an event definition to Marbles, and updated the TradeMarble transaction to emit the event. I have a node red flow that says it is connected to my fabric instance running locally. I also have composer-rest-server up and running, and am using that to execute the TradeMarble transaction. Everything seems to be working, i.e. I see the owner of the marble change after I execute the transaction, but I get nothing in my node red flow. I have the composer in node wired to a debug node. I expect to see debug statements, but I get nothing. I have composer 0.7.5 installed and I am using hlfv1 alpha1. ```event MarbleTradedEvent identified by eventId { o String eventId o String marbleId o String marbleSize o String marbleColor }``` ``` function tradeMarble(tradeMarble) { tradeMarble.marble.owner = tradeMarble.newOwner; var factory = getFactory(); var marbleTraded = factory.newEvent('org.hyperledger_composer.marbles', 'MarbleTradedEvent'); emit(marbleTraded); return getAssetRegistry('org.hyperledger_composer.marbles.Marble') .then(function (assetRegistry) { return assetRegistry.update(tradeMarble.marble); }); }``` Anybody have a working example?

@dwakeman -- I know @caroline-church has demoed that. She may have a flow she can share.

dselman (Wed, 14 Jun 2017 08:34:48 GMT):
@hariharanatarajan we don't have any tooling to automatically refactor/rename model elements at present.

dselman (Wed, 14 Jun 2017 08:35:12 GMT):
The error messages should guide you - if they do not, then we have an issue. ;-)

caroline-church (Wed, 14 Jun 2017 08:36:48 GMT):
Hi @dwakeman i assume you are using node red locally and not on bluemix? do you have more than one business network running could the node-red node be connected to a different business network than you have marbles deployed to? Have you tried submitting the transaction from the node-red flow to check if that works?

rama_rahul (Wed, 14 Jun 2017 09:35:50 GMT):

hey there!

Pere-Lluis (Wed, 14 Jun 2017 11:08:44 GMT):
Does anybody know how to a asset registry in a logic.js?

Pere-Lluis (Wed, 14 Jun 2017 11:09:20 GMT):
I'm trying to check if one asset exists there but I don't find how to access the elements in the registry

caroline-church (Wed, 14 Jun 2017 11:09:44 GMT):
`getAssetRegistry('org.acme.sample.SampleAsset')`

caroline-church (Wed, 14 Jun 2017 11:10:21 GMT):
that returns a promise

caroline-church (Wed, 14 Jun 2017 11:10:42 GMT):
so then you can do `assetRegistry.get('assetId`)`

Pere-Lluis (Wed, 14 Jun 2017 11:10:50 GMT):
so if I want to do a .forEach asset in that registry?

Pere-Lluis (Wed, 14 Jun 2017 11:11:03 GMT):
how should I do it?

caroline-church (Wed, 14 Jun 2017 11:11:46 GMT):
oh you can do `assetRegistry.getAll()`

Pere-Lluis (Wed, 14 Jun 2017 11:13:08 GMT):
okey so it should look like this getAssetRegistry('org.basetis.bonusetis.split') assetRegistry.getAll().forEach(function(split){ if(split.owner.$identifier==receiver.$identifier){ existeix=true } })

Pere-Lluis (Wed, 14 Jun 2017 11:13:19 GMT):
thanks

Pere-Lluis (Wed, 14 Jun 2017 11:13:28 GMT):
I'll try now

Pere-Lluis (Wed, 14 Jun 2017 11:13:33 GMT):
thank you very much!

caroline-church (Wed, 14 Jun 2017 11:13:46 GMT):
yeah something like that

Pere-Lluis (Wed, 14 Jun 2017 11:16:16 GMT):
I'm sorry to keep bothering but I can't get it to work

Pere-Lluis (Wed, 14 Jun 2017 11:16:34 GMT):
when I try the getAll()

Pere-Lluis (Wed, 14 Jun 2017 11:17:04 GMT):
should I do it over getAssetRegistry('org.acme.sample.SampleAsset') ?

Pere-Lluis (Wed, 14 Jun 2017 11:33:14 GMT):
Okey I got it doing:

Pere-Lluis (Wed, 14 Jun 2017 11:33:18 GMT):
return getAssetRegistry('org.basetis.bonusetis.split') .then(function (assetRegistry) { // Update the asset in the asset registry. return assetRegistry.getAll() .then(function(splits){ splits.forEach(function(split){ if(split.owner.$identifier==receiver.$identifier){ existeix=true } }) }) })

but if you know a more straightforward way, let me know

caroline-church (Wed, 14 Jun 2017 12:14:47 GMT):
instead of going through them all you could just try a get on the one you want to see if exists

[ ](https://chat.hyperledger.org/channel/composer?msg=mPibhyvpmsLcnQjSJ) @caroline-church I do have two networks deployed, but I specified the one I wanted on the node. Node red is running locally. I will try to submit a transaction from node red and see if that works. Thanks!

dwakeman (Wed, 14 Jun 2017 13:17:45 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=RhXudKuMtJyawpRET) @hariharanatarajan ah, okay. Technically you can do that in playground, as it does allow you to edit all of that, but you're correct, an IDE like VS Code or ATOM would have more sophisticated refactoring support that would make it easier. You can do that too, just like I described, and when you are all done with everything you can use the `composer archive create` command to create a new bna file to import into playground.

@caroline-church I tried using the composer-out node to submit a transaction, and that didn't throw an error I could find, but it also didn't work. I used the same JSON I submitted in the rest api explorer as the msg.payload, and verified that I was using a value for newOwner that is different than the current owner of the marble. The owner value does not change.

caroline-church (Wed, 14 Jun 2017 13:45:09 GMT):
@dwakeman can you create assets or retrieve assets?

caroline-church (Wed, 14 Jun 2017 13:46:02 GMT):

the last one is me trying to retrieve a marble. that's the most descriptive error I've gotten so far.

caroline-church (Wed, 14 Jun 2017 14:02:20 GMT):
ahh so in this case you have the namespace wrong, so whatever you have set for the `$class` property isn't right

dwakeman (Wed, 14 Jun 2017 14:08:39 GMT):
yes, it is.. I grabbed it from the composer-rest-server api explorer

dwakeman (Wed, 14 Jun 2017 14:09:09 GMT):
so perhaps it's not connecting to the right business network?

dwakeman (Wed, 14 Jun 2017 14:12:49 GMT):
This is the code in my Function node to set the msg.payload: ```var marble = { "$class": "org.hyperledger_composer.marbles.Marble", "id": "smred1" } msg.payload = marble; return msg;```

Hi is anyone aware of a threat model for Fabric/Composer? I've asked in #Fabric in regards to v1 (as channels are important to my use case), would something similar exist for Composer? As part of the blockchain technology evaluation for my company I have been tasked to produce a threat model for the different platforms we are considering (Fabric being one). I have a meeting with security management this week to start this review off, and would appreciate if there's anything already out there that might help me save some time and effort putting one together.

CT123 (Wed, 14 Jun 2017 16:15:03 GMT):
@davidkel -- quick update - and thanks for your suggestions and comments. Appears I was able to get playground to run locally or at least the npm install exited with success -- see below. Steps included stopping and restarting docker; flushing npm-debug.log and then simply re-running npm install. As an aside, my system runs 'traditional' root, not sudo. When you install npm in my environment (macos running Sierra) it gives you the option to make it available to the entire system or to just an individual user. In my case it won't matter but in general when I install I install apps I do so for every user so there is a single instance that I can test against with different users. Again, npm installs systemwide in /usr/local/bin and every user has access to that directory, etc. Also -- I was finally able to get composer playground to launch from a browser instance after trying for a couple of weeks -- the key -- you need to let users know that playground will not run in 'private browsing' mode. Which candidly is an issue. Once I opened a non-private or standard browser window I was able to get the online version of playground running. Someone may want to document that.

Hey everyone, I just watched the car demo of the Hyperledger Composer project. It was a great example except I am confused how different parties sign transactions on the blockchain. When they created a new user in the video, it provided a user secret for that user, is this essentially the private key that would be used to sign transactions?

if I have an AdminParticipant, how can I define an ACL rule that only they can create a UserParticipant?

[ ](https://chat.hyperledger.org/channel/composer?msg=JQSsqyYvXZy6FSP58) @caroline-church Quick update.... I undeployed my other two networks, and restarted my node-red server. Now I can execute transactions, get assets and receive events! Not sure if it was the restart of node-red or the fact that I got rid of the other networks, but happy that it works. One more question. All I am getting back is this: ```"Resource {id=org.hyperledger_composer.marbles.MarbleTradedEvent#aff296d0-e637-4822-9533-3a3ee05e5c71#0}"``` My event has several attributes that I populate before emitting the event. I expected to see them in the JSON I got back from the subscription. Is that correct?

hi everyone, just a reminder that our Community call is 9am UTC (10am UK, 2:30pm IST, 5pm CST) tomorrow(Thursday) - would love to hear about the things you like/don't like /your experiences with Composer ! Meeting details are here: https://github.com/hyperledger/composer/wiki/Meeting-15th-June-2017 (presently looking at discussing Query support, HLF v1 beta support, Vehicle Lifecycle demo status) - cheers - have a nice day/evening etc, Paul

caroline-church (Thu, 15 Jun 2017 07:08:52 GMT):
Hi @dwakeman glad you got it to work, to see all the attributes you need to upgrade the version of node-red-contrib-composer, the working version should be 0.0.2, it was a bug in 0.0.1. The easiest way i found to update the nodes is to `cd ~/.node-red` and do an `npm install node-red-contrib-composer`

Hi @annbnn you should ask this in the #fabric channel this doesn't seem to be a composer issue

one more question.... Any word on if/when it will work with Node Red on Bluemix?

caroline-church (Thu, 15 Jun 2017 14:14:03 GMT):
hopefully it will do soon, it needs work around the connection profiles, feel free to raise an issue on github for it, and maybe even add the function yourself

okay, will do!

dwakeman (Thu, 15 Jun 2017 14:23:53 GMT):
is it node-red-contrib-composer or node-red-contrib-fabric-composer? I found the latter in github under ibm-early-programs, but not sure that's the right repo.

yes

as of now or it'll be updated?

Jakeeyturner (Thu, 15 Jun 2017 14:44:56 GMT):
digitalproperty will be @uber.twin. The new vehicle-lifecycle demo won't be compatible immediately, as it needs to be updated to work with beta-1.0.0

caroline-church (Thu, 15 Jun 2017 15:02:28 GMT):
@davidoevans when you create an identity you can specify whether that new identity can issue identities themselves

@davidoevans when you issue an identity you can specify whether that new identity can issue identities themselves

davidoevans (Thu, 15 Jun 2017 15:02:59 GMT):
so the only extra thing is how to specify which identities they can create

see https://hyperledger.github.io/composer/unstable/reference/composer.identity.issue.html

@jaguarg then to deploy a network (so long as you have downloaded the fabric-dev-server from composer-tools and run createComposerProfile.sh) using the command `composer network deploy -a -p hlfv1 -i PeerAdmin -s anything` (the secret isn't used, but at the moment the cli tools still mandate it)

the deploy command is : `composer network deploy -a ./mytest.bna -i PeerAdmin -s anythingwilldo`

davidkel (Thu, 15 Jun 2017 15:51:36 GMT):
@jaguarg you must specify the hlfv1 connection profile, which is missing from the deploy command. Try this command `composer network deploy -a ./mytest.bna -i PeerAdmin -s anythingwilldo -p hlfv1`

Hey guys, is there a way in composer to pass back a payload on a transaction ? Basically I would like to make it so that when I call a transaction I get passed back some sort of data that was not stored in the ledger.

MeenakshiSingh (Thu, 15 Jun 2017 16:51:22 GMT):
In a 0.6 fabric setup with peers running on 4 remote nodes, are these ```- CORE_PBFT_GENERAL_BATCHSIZE=1 - CORE_PBFT_GENERAL_K=2 - CORE_PBFT_GENERAL_MODE=batch - CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN=pbft # noops, pbft - CORE_NOOPS_BLOCK_TIMEOUT=2s - CORE_NOOPS_BLOCK_WAIT=2s

@davidkel I am having exact same issues as described above by @jaguarg. I have all the same outputs (running the 1.0-beta fabric and also have installed the latest composer version 0.8.0) and am specifying the connection profile but still getting an error

emlorc01 (Thu, 15 Jun 2017 17:49:02 GMT):
Error: event message must be properly signed by an identity from the same organization as the peer: [failed deserializing event creator: [Expected MSP ID Org1MSP, received ]]

dselman (Thu, 15 Jun 2017 17:56:06 GMT):
@jorgedr no, not yet. That is this issue: https://github.com/hyperledger/composer/issues/998

dselman (Thu, 15 Jun 2017 17:57:47 GMT):
@emlorc01 mmmm, this smells like a configuration bug... We have system tests that emit events and they passed, so there's some sort of config issue here. We will investigate.

dselman (Thu, 15 Jun 2017 17:58:27 GMT):
Fabric has been progressively tightening up the security and adding more and more certs...

emlorc01 (Thu, 15 Jun 2017 17:58:40 GMT):
@dselman ok. please let me know if there is any details I need to provide because I have been spending quite a lot of hours trying to fix this one with no luck

dselman (Thu, 15 Jun 2017 18:01:39 GMT):
@davidkel -- it looks like this is coming from validateEventMessage in https://github.com/hyperledger/fabric/blob/master/events/producer/handler.go#L150

dselman (Thu, 15 Jun 2017 18:02:13 GMT):
You should have more details in the logs

dselman (Thu, 15 Jun 2017 18:02:46 GMT):
@emlorc01 Can you retrieve the logs (using docker logs) from the chaincode container and peer?

dselman (Thu, 15 Jun 2017 18:05:36 GMT):
@emlorc01 what participant/identity are you processing the transaction as?

emlorc01 (Thu, 15 Jun 2017 18:06:08 GMT):
@dselman I was just trying to use the PeerAdmin identity

emlorc01 (Thu, 15 Jun 2017 18:06:27 GMT):
@dselman composer network deploy -a ./my-network.bna -i PeerAdmin -s abc

emlorc01 (Thu, 15 Jun 2017 18:13:21 GMT):
I'm trying to get the docker logs command to output to a file so I can attach here but it is not working

dselman (Thu, 15 Jun 2017 18:32:09 GMT):
You get this when you deploy a network?

dselman (Thu, 15 Jun 2017 18:33:06 GMT):
For the deploy you need to use PeerAdmin. Is this using the one-line install script we provided to stand up the Fabric?

emlorc01 (Thu, 15 Jun 2017 18:33:36 GMT):
I tried to use PeerAdmin the first time, then I switched when you asked me to try the admin/adminpw combination

emlorc01 (Thu, 15 Jun 2017 18:34:01 GMT):
to stand up the fabric I followed instructions at https://hyperledger.github.io/composer/installing/development-tools.html

dselman (Thu, 15 Jun 2017 18:34:08 GMT):
Sorry, I thought you where trying to emit an event from a TP function, I didn't realize this was during a deploy

emlorc01 (Thu, 15 Jun 2017 18:34:35 GMT):
ah ok. yes I was working my way through the Developer tutorial and was going fine until I get to the part where I deploy my sample network to the fabric instance

andreaslbauer (Thu, 15 Jun 2017 18:34:54 GMT):
For what it's worth - I get the same exact error in the same scenario, working through the dev tutorial step by step.

dselman (Thu, 15 Jun 2017 18:35:23 GMT):
So, you followed this install: https://hyperledger.github.io/composer/installing/using-playground-locally.html

emlorc01 (Thu, 15 Jun 2017 18:35:55 GMT):
no I did the one below that

dselman (Thu, 15 Jun 2017 18:35:55 GMT):
Let me try on my system... One sec

emlorc01 (Thu, 15 Jun 2017 18:36:06 GMT):
the one called "installing a developer environment"

andreaslbauer (Thu, 15 Jun 2017 18:36:06 GMT):
This one for me: https://hyperledger.github.io/composer/tutorials/developer-guide.html

andreaslbauer (Thu, 15 Jun 2017 18:36:43 GMT):
I deployed the bna successfully to the hosted and local playgrounds.

andreaslbauer (Thu, 15 Jun 2017 18:43:02 GMT):
A few more bits of information for my scenario (I think emlorc01 has the same): use FABRIC_VERSION=hlfv1, all steps building and unit test and deploy to sand box work fine, it is the deploy to local fabric that fails with this error

emlorc01 (Thu, 15 Jun 2017 18:43:22 GMT):
yes. same for me

davidkel (Thu, 15 Jun 2017 18:45:11 GMT):
@emlorc01 you aren't specifying the connection profile in your command. You need to specify `composer network deploy -a ./my-network.bna -i PeerAdmin -s abc -p hlfv1` you need to ensure you have run the `createComposerProfile.sh` script as this creates the hlfv1 profile and sets up the PeerAdmin userid

davidkel (Thu, 15 Jun 2017 18:46:55 GMT):
@theophoric you haven't specified a profile, therefore it will create and use a default profile which only works with hlf v0.6. If you followed the tutorials then the hlfv1 profile will have been created for you. so for your command do the following `composer network deploy -a fitchain-composer@0.0.1.bna -i admin -s adminpw -p hlfv1`

emlorc01 (Thu, 15 Jun 2017 18:47:38 GMT):
oh! it worked now

theophoric (Thu, 15 Jun 2017 18:47:51 GMT):
yup.. good catch thanks

emlorc01 (Thu, 15 Jun 2017 18:48:09 GMT):
oh dear I feel silly for forgetting that, I did run the script to set up the profile but apparently missed it in the deploy command

emlorc01 (Thu, 15 Jun 2017 18:49:36 GMT):
thanks very much @davidkel & @dselman !

davidkel (Thu, 15 Jun 2017 18:49:42 GMT):
@emlorc01 no worries, glad you are up and running

jaguarg (Thu, 15 Jun 2017 19:09:57 GMT):

davidkel (Thu, 15 Jun 2017 19:17:31 GMT):
@dselman don't think hyperledger fabric 1.0 will be doing anything about this

davidkel (Thu, 15 Jun 2017 19:17:31 GMT):
@dselman don't think hyperledger fabric 1.0 will be doing anything about this, hopefully post 1.0 things will improve

dselman (Thu, 15 Jun 2017 19:44:03 GMT):
Shout out to @tobiashunter for his great job updating the graphics (which have turned into videos!) for the Developer Tutorial. Very slick! https://hyperledger.github.io/composer/tutorials/developer-guide.html

andreaslbauer (Thu, 15 Jun 2017 19:51:12 GMT):
I still get the error on deployment. Here is the command I am using, it does have the generated profile name specified with -p: composer network deploy -a my-network.bna -i PeerAdmin -s randomString -p hlfv1. Probably I am missing something very simple.

davidkel (Thu, 15 Jun 2017 19:56:37 GMT):
@andreaslbauer can you provide the error just to make sure it is the same, then could you do a docker ps and post the results ?

andreaslbauer (Thu, 15 Jun 2017 19:58:03 GMT):
I think I found something. Let me try something and I will let you know whether I figured it out.

andreaslbauer (Thu, 15 Jun 2017 20:02:40 GMT):
and this is probably what needs to be specified with -s when deploying. How do I set it?

davidkel (Thu, 15 Jun 2017 20:07:21 GMT):
@andreaslbauer PeerAdmin is just a label for the crypto material that should already be your KeyValStore so no enrollmentSecret is required. Can you confirm you have composer v0.8.0 ?

andreaslbauer (Thu, 15 Jun 2017 20:13:25 GMT):
composer -v reports v0.7.5

davidkel (Thu, 15 Jun 2017 20:14:07 GMT):
@andreaslbauer ah, that's the problem only v0.8.0 will work with hyperledger fabric 1.0 beta

andreaslbauer (Thu, 15 Jun 2017 20:15:10 GMT):
Got it. Thank you so much!

Mattasher (Thu, 15 Jun 2017 20:52:57 GMT):
@dselman To make sure I'm understanding the system, this compiles down to code that runs on Fabric and gives us a guarantee that when the transaction is run on the latest "live" data based on the derived state from all committed transactions up to that moment (including whatever happens first based on the ordering service for that block).

dselman (Thu, 15 Jun 2017 20:54:17 GMT):
Yes. The transactional model is identical, irrespective of whether you use Composer or base Fabric.

sstone1 (Fri, 16 Jun 2017 08:23:02 GMT):
because it's a major version bump you will also need to deploy the business network again.

sstone1 (Fri, 16 Jun 2017 08:23:29 GMT):
@deepakvparmar and for your next question - Composer provides a layer of abstraction on top of a Blockchain platform. Currently 90% of the code in Composer has no idea that it is working with Hyperledger Fabric - it's been designed from the start to be portable.

sstone1 (Fri, 16 Jun 2017 08:23:52 GMT):
As long as a Blockchain platform supports the ability to execute JavaScript (and Sawtooth does) then we should be able to port the Composer code to run on it.

sstone1 (Fri, 16 Jun 2017 08:25:09 GMT):
It is a matter of porting the 10% of Composer code that is dependent on the Blockchain platform. There are two bits to this: 1) the connectors, which allow the Composer client to send requests to the Blockchain and 2) the runtime containers, which let the Composer runtime use the underlying Blockchain APIs (think GetState()/PutState() in Fabric).

@sstone1 @dselman : Is there any way in hyperledger composer that we can fetch smart contract into golang code after deploying bna file using composer?

sstone1 (Fri, 16 Jun 2017 09:11:06 GMT):
@deepakvparmar there is no Go code being generated when you deploy a business network. The only Go code is the generic Composer runtime which understands and executes your business network definition.

sstone1 (Fri, 16 Jun 2017 09:12:23 GMT):
Generic Composer runtime === our chaincode/smart contract which is used for all deployed business networks.

mbwhite (Fri, 16 Jun 2017 09:12:24 GMT):
@djarillo With that error I believe you are using the lastest Hypleder Composer version but with an older alpha probably level of Hyperledger Fabric

Our Composer runtime and your busines network definition get deployed to the Fabric. Our Composer runtime

sstone1 (Fri, 16 Jun 2017 09:13:28 GMT):
is the chaincode and your business network definition is stored in the world state.

@djarillo ... could you run `composer -v` and `docker ps` please so we can see what exact version you've got running.

sstone1 (Fri, 16 Jun 2017 09:18:53 GMT):
@deepakvparmar you'll still see standard Fabric chaincode and blocks in the Hyperledger Explorer - it's just a standard Fabric chaincode under the covers!

sstone1 (Fri, 16 Jun 2017 09:19:14 GMT):
Each business network deploys its own copy of the Composer runtime chaincode.

djarillo (Fri, 16 Jun 2017 09:19:21 GMT):
@mbwhite The versions... composer-cli v0.7.5 composer-admin v0.7.5 composer-client v0.7.5 composer-common v0.7.5 composer-runtime-hlfv1 v0.7.5 hyperledger/fabric-peer:x86_64-1.0.0-beta

I have also created an abstract asset Customer and an asset Person (extends Customer). Customer contains field "o Address customerAddress". When creating a new Person in composer, of course at first (when dynamically checking the syntax) I get the error: "Error: Cannot instantiate Abstract Type Address in namespace com.ibm.si.electricitymarket". I change the class Address to SlovenianAddress and dynamic syntax checker does not detect any more errors and "Create New" button gets enabled. However, when clicking "Create New", I get this error again: "Error: Error: Cannot instantiate Abstract Type Address in namespace com.ibm.si.electricitymarket". Any idea?

dselman (Fri, 16 Jun 2017 12:10:56 GMT):
Just to be clear for everyone... the BNA file (business network archive) is completely independent of Fabric version. I.e a BNA file you created with version 0.7 of Composer and tested with version 0.6 of Fabric should work unchanged with Composer 0.8 and Fabric v1-beta1. HOWEVER -- you will need to install the v0.8 composer-cli and HLF runtime and redeploy the network when you upgrade.

FelixNielsen (Fri, 16 Jun 2017 12:18:23 GMT):
just curious - what about backup of the composer state db and the hyperledger? - if a restore is needed? is that even possible

davidkel (Fri, 16 Jun 2017 12:22:16 GMT):
@FelixNielsen Composer will be using whatever is provided by the hyperledger fabric system it uses. I would suggest asking on the #fabric or #fabric-questions channel about operational aspects of fabric such as disaster recovery

mattalhonte (Fri, 16 Jun 2017 19:53:32 GMT):
Which is doubly lame because it was totally working a few days ago :/

davidkel (Fri, 16 Jun 2017 20:05:05 GMT):
@mattalhonte do you mean rest suddenly stopped working and nothing has been changed or you have made changes and it's stopped working ?

mattalhonte (Fri, 16 Jun 2017 20:05:34 GMT):
I don't recall making any changes. I did stop it and start it back up.

davidkel (Fri, 16 Jun 2017 20:06:45 GMT):
@just the rest server ? The error you describe looks as though you are trying to working with a totally clean fabric which has no business network deployed

davidkel (Fri, 16 Jun 2017 20:06:45 GMT):

mattalhonte (Fri, 16 Jun 2017 20:09:03 GMT):
Since then, I tried cleaning Fabric. I did ```docker kill $(docker ps -q) docker rm $(docker ps -aq) docker rmi $(docker images dev-* -q) ./stopFabric.sh ./teardownFabric.sh ./downloadFabric.sh ./startFabric.sh ./createComposerProfile.sh```

mattalhonte (Fri, 16 Jun 2017 20:09:11 GMT):
But it wasn't working before then either

mattalhonte (Fri, 16 Jun 2017 20:10:37 GMT):
did that make things worse maybe?

mattalhonte (Fri, 16 Jun 2017 20:14:27 GMT):
oh, whoops

mattalhonte (Fri, 16 Jun 2017 20:16:18 GMT):
I see now. Had to redeploy the network.

mattalhonte (Fri, 16 Jun 2017 20:16:33 GMT):
No clue why it broke before, but working now. Thanks! :)

@mattalhonte phew, glad you are back and working. :-)

Anyone upgraded to Fabric 1.0 Beta?

mattalhonte (Fri, 16 Jun 2017 20:26:09 GMT):
Oh, also, for Angular apps - trying to get it to display Transactions as well as assets. I notice a lot of commented-out code referring to Transactions - how hard would it be to jury-rig something that displayed Transactions too?

klorenz (Fri, 16 Jun 2017 21:46:33 GMT):

@mattalhonte re transactions, I added transactions to the demo app, it's in my github repo here https://github.com/ianco/fabric-app

ianco (Fri, 16 Jun 2017 22:07:55 GMT):
it's just a call to another web service

@ianco if you can generalize that we'd love to see the Yeoman templates updated to generate components to view and submit transactions.

@jdockter they are in a separate `vehicle-lifecycle-models` package here: https://github.com/hyperledger/composer-sample-models/tree/master/packages/vehicle-lifecycle-model/models

sstone1 (Sat, 17 Jun 2017 07:47:08 GMT):
@Binay1 if you are using HLFv1 beta 1 (Composer v0.8.0) then you need to deploy a business network using a peer admin user ID - when you use the `fabric-dev-servers` provided by Composer this is the `PeerAdmin` ID

sstone1 (Sat, 17 Jun 2017 07:47:22 GMT):
`admin` does not have permission to install chaincode onto a peer

davidkel (Sat, 17 Jun 2017 08:00:51 GMT):
I have created some stackoverflow items of the common problems being hit when moving to composer v0.8.0. If anyone is having problems deploying business networks with stackoverflow may have the answer

stormli (Sat, 17 Jun 2017 12:03:53 GMT):
Hi everyone, Here is Storm from IBM z/OS Connect dev team. I have setup hyperledger composer sample vehicle lifecycle. and try to call the restful API provided by this sample. But when I review the swagger of this restful API. I met some issue. I talked to Jake Turner. He suggested me post questions here. Can someone have a look? Thanks. 1. basePath: /api, relativePath: /ScrapVehicle, method: POST. It refer to #/definitions/VehicleTransaction. but there is no definition in this swagger. 2. path /system/transactions/{id} GET I think this operation is used to get transaction by ID. The response defined in swagger is "responses": { "200": { "description": "Request was successful", "schema": { "type": "object" } } it doesn't contain detail format of transaction. I am wondering why detailed format is not provided. Without these detail information, how consumer knows how to format the response?

dselman (Sat, 17 Jun 2017 12:29:50 GMT):
Which version of Composer are you using?

dselman (Sat, 17 Jun 2017 12:29:55 GMT):
`composer --version`

stormli (Sat, 17 Jun 2017 12:51:55 GMT):
I don't know. someone set up it for me. should be the latest version. Let me ask. If you can access IBM network. here is the swagger of our composer server. http://winlnxnz.hursley.ibm.com:44444/explorer/ maybe you can recognize version from this swagger?

stormli (Sat, 17 Jun 2017 13:00:16 GMT):
http://winlnxnz.hursley.ibm.com:44444/explorer/swagger.json Here is the swagger I am looking at. #/definitions/org_vda_VehicleTransaction is the definition can't be found in swagger.

dstarina (Sat, 17 Jun 2017 13:39:19 GMT):
@dselman Does Composer support multiple channels?

davidkel (Sat, 17 Jun 2017 13:46:15 GMT):
@dstarina Channels are an isolation concept which have their own blockchains, how would you want to use multiple channels ?

dstarina (Sat, 17 Jun 2017 13:50:25 GMT):
@davidkel Sorry, I guess I misunderstook the concept of a channel. So it is not possible to share an asset between different channels? What I really want to know is, how can we insure privacy on the blockchain - when having different competitors using the same blockchain, we don't want them to be able to reverse-enginer blockchain and somehow be able to read the data about their competitors from the blockchain and/or world state database

davidkel (Sat, 17 Jun 2017 13:57:46 GMT):
@dstarina No you can't share assets directly, but it is possible to connect external systems to composer so you might be able to use those mechanisms. As for your other question, that is an excellent question and would be good to ask the fabric guys their opinion on this.

dstarina (Sat, 17 Jun 2017 14:00:50 GMT):
@davidkel Will do, thank you

@davidkel which files do we need to use with `composer identity import` ?

sstone1 (Sat, 17 Jun 2017 14:34:55 GMT):
from the crypto-config directory i mean

davidkel (Sat, 17 Jun 2017 14:50:51 GMT):
@sstone1 you need the file in the keystore and the file from the signer cert

sstone1 (Sat, 17 Jun 2017 14:51:49 GMT):
ta!

davidkel (Sat, 17 Jun 2017 14:52:49 GMT):
@sstone1 the example on this page shows the directory structure if cryptogen was used https://hyperledger.github.io/composer/reference/composer.identity.import.html

rohilsurana (Sun, 18 Jun 2017 11:34:06 GMT):
Hi, I have been trying of creating a token system using composer but I am unable to understand. for example - for a transfer of tokens, how I can reduce ones asset and increase someone elses at the same time. If I give them the permission to edit there asset they can use the API to increase the value of it?

sstone1 (Sun, 18 Jun 2017 14:33:05 GMT):
@rohilsurana you can specify that an ACL rule only applies in the scope of a transaction, for example: ``` rule R1 { description: "Test R1" participant(p): "org.acme.sample.SampleParticipant" operation: UPDATE resource(a): "org.acme.sample.SampleAsset" transaction: "org.acme.sample.SampleTransaction" condition: (p.getIdentifier() === a.owner.getIdentifier()) action: ALLOW } ``` this rule only allows a SampleParticipant to update a SampleAsset if they own that SampleAsset, and only if a SampleTransaction is executing

rohilsurana (Sun, 18 Jun 2017 15:18:42 GMT):
@sstone1 thanks!! :D

dselman (Sun, 18 Jun 2017 16:13:48 GMT):

One thing - these connection profiles... Why is there a difference between the Service Credential json and connection profiles? I would ideally just want to export all configs I need right from server and dump it for client to pickup

Pasteis (Sun, 18 Jun 2017 18:27:15 GMT):
Simon has a very good explanation on how to connect to bluemix here... https://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service/42354002#42354002

Pasteis (Sun, 18 Jun 2017 18:28:39 GMT):
but ideally... this could be a straight json dump - or am I missing something around connection profiles, i.e is it used for other thing ?

sstone1 (Mon, 19 Jun 2017 01:59:08 GMT):
@Pasteis connection profiles are designed such that Composer can connect to a variety of different Blockchain platforms. There's a lot of redundant information in the service credential JSON that Composer cannot use, and the service credential documents are difficult for anyone to manually write when connecting to their own Hyperledger Fabric instances. On an IBM note, we are looking at extending Bluemix with the option to download a Composer connection profile.

mbwhite (Mon, 19 Jun 2017 08:41:38 GMT):
@wael Hypeledger Fabric, uses a GRPC protocol - and for the NodeJS GRPC module that Composer uses this relies on native code being complied. This error is indicative that some thing has not compiled correctly during the phase.

mbwhite (Mon, 19 Jun 2017 08:42:03 GMT):
What platform are running on? Mac/ Linux, or a LinuxVM .

No

mbwhite (Mon, 19 Jun 2017 09:02:15 GMT):
ok, that might explain this ; that is needed for Mac to compile the native code modules. Note that after you've installed it a npm rebuild would be required to make sure the modules are rebuilt.

davidkel (Mon, 19 Jun 2017 11:46:52 GMT):
@xuzhao103389 You can only deploy to a peer using a Peer Admin identity. You need to import a Peer Admin user identity into the composer connection profile keyValStore before you can deploy to that peer. See https://hyperledger.github.io/composer/reference/composer.identity.import.html on importing identities. Also I see you have 2 peers. If they are of the same organisation and have the same admin user then you can deploy to both at the same time, otherwise you are going to have to have 2 connection profiles plus you would need to import the identity of the second peer into the 2nd connection profile KeyValStore (I would highly recommend not using the same directory for both profiles)

davidkel (Mon, 19 Jun 2017 11:49:01 GMT):
@stormli In answer to your 2nd question, the reason it is defined as object is because there is a single transaction registry for all transactions not 1 per transaction definition. When a request for a transaction id is made it could be 1 of however many types of transaction that have been defined, so the only possible swagger definition can be to return a type of object

davidkel (Mon, 19 Jun 2017 12:10:41 GMT):
@stormli regarding your first question this is a know issue. Please see https://github.com/hyperledger/composer/issues/1055

@xuzhao103389 you need to import the crypto material from the hyperledger fabric environment. SO however you have run hyperledger fabric 1.0.0-beta the peers will point to it's MSP configuration and you will find the users that peer will recognise within that MSP configuration directory structure

xuzhao103389 (Mon, 19 Jun 2017 12:43:43 GMT):
so do I have to dowload the fabrc source code? @davidkel

davidkel (Mon, 19 Jun 2017 12:44:43 GMT):
@xuzhao103389 I don't know how you have set up your fabric beta environment. In order to run the fabric beta you must have the MSP definitions for the peer.

xuzhao103389 (Mon, 19 Jun 2017 12:47:00 GMT):
I remember the composer should be independent from fabric right? @davidkel , I thought what I need to do is using the fabric beta images

davidkel (Mon, 19 Jun 2017 12:52:13 GMT):
@xuzhao103389 I don't know how you have setup and run your fabric beta server, did you follow the composer guides and use dev server on composer-tools or have you been setting up your own fabric beta using the hyperledger fabric getting started guide ?>

xuzhao103389 (Mon, 19 Jun 2017 12:55:35 GMT):
@davidkel so I have a running env for composer-sample-applications-hlfv1/, today I upgraded composer to V0.8, and then I downloaded the examples from https://github.com/hyperledger/composer-sample-networks

xuzhao103389 (Mon, 19 Jun 2017 12:55:52 GMT):
after that, I find the issues

davidkel (Mon, 19 Jun 2017 12:58:11 GMT):
@xuzhao103389 composer-sample-applications-hlfv1 has been archived. It was based on hyperledger fabric alpha1. Composer v0.8.0 can only work with hyperledger fabric 1.0 beta. We have changed how you can obtain a fabric v1 development server. More info can be found at https://hyperledger.github.io/composer/installing/development-tools.html if you want to continue using hyperledger fabric alpha1 then you must stay with composer v0.7.5

xuzhao103389 (Mon, 19 Jun 2017 12:58:36 GMT):
thanks

hey - has anyone seen the following error message before after running the composer-rest-server command in terminal and inputting values to the questions asked: Error: event message must be properly signed by an identity from the same organization as the peer: [failed deserializing event creator: [Expected MSP ID Org1MSP, received ]]

elisabetta (Mon, 19 Jun 2017 13:11:10 GMT):
@harj91: I got the same message when I was trying to use a composer version which didn't support hyperledger beta (which was the blockchain runtime version I was running)

elisabetta (Mon, 19 Jun 2017 13:13:16 GMT):
not sure whether composer supports hyperledger v1.0 beta version yet. In my case, I had to go back to alpha version and everything worked fine.

elisabetta (Mon, 19 Jun 2017 13:19:34 GMT):
@harj91: I'm just reading above that new composer v0.8.0 only supports beta. So, if you have that version installed then it must be something else

Jakeeyturner (Mon, 19 Jun 2017 13:27:43 GMT):
Once you've deployed the business network using PeerAdmin, you can connect and use the network as you would normally. E.g. with username: admin password: adminpw

Jakeeyturner (Mon, 19 Jun 2017 13:27:56 GMT):
It's only at the deployment stage that you need to use PeerAdmin

harj91 (Mon, 19 Jun 2017 13:31:03 GMT):
@Jakeeyturner even when i use admin and adminpw, the same error message is given

davidkel (Mon, 19 Jun 2017 13:34:36 GMT):
@harj91 what version of composer-rest-server are you running, bet it isn't 0.8.0

wael (Mon, 19 Jun 2017 13:37:14 GMT):
@mbwhite I have installed xcode and rebuild npm as you told me , but still the same problem . I can create new profile with adminconnection.createProfile(..) , but whenever I want to connect the profile created it outputs : Error: Failed to load connector module "composer-connector-hlfv1" for connection profile "testprofile"

wael (Mon, 19 Jun 2017 13:37:29 GMT):
also tried with hlf 0.6 , same error

@harj91 that only tells me what version the cli is, sorry.

davidkel (Mon, 19 Jun 2017 13:50:41 GMT):
@harj91 try the command `npm list -g --depth=0 | grep composer-rest-server`

@davidkel ah thanks, you're right its ├── composer-rest-server@0.7.5. how can i update this to 0.8.0?

davidkel (Mon, 19 Jun 2017 14:00:20 GMT):
@harj91 easiest why is to do npm uninstall -g composer-rest-server then npm install -g composer-rest-server

davidkel (Mon, 19 Jun 2017 14:00:20 GMT):

I am confused here

xuzhao103389 (Mon, 19 Jun 2017 14:57:41 GMT):
Choose which version of Fabric to use. For v0.6 this needs to be set explicitly as follows. export FABRIC_VERSION=hlfv0.6 Hyperledger Fabric v1.0-alpha is the default, but to 'unset' the v0.6, or to be explicit in using v1 use this command export FABRIC_VERSION=hlfv1

xuzhao103389 (Mon, 19 Jun 2017 14:57:56 GMT):
is that still for alpha?

@xuzhao103389 With composer v0.8, references to hlfv1 will only mean beta. Support for alpha was dropped in Composer v0.8

Composer and Fabric on Linux Red-Hat: Recently I installed VSCode, Composer and Fabric on Ubuntu 16.04. A client asks if we can install on Red-Hat. They have several reasons to ask, however, the most important one is that the have standardized all on Red-Hat. Automated image creations etc. Well, is Red-Hat supported? In the dev-guide I noticed Ubuntu 14.x and 16.04. Please advice.

@xuzhao103389 when you type `composer -v` what response do you get ? It's just if the command doesn't exist that isn't the error you would get. It might be you have another totally unrelated command called 'composer' on your machine that is being picked up ?

davidkel (Mon, 19 Jun 2017 17:20:59 GMT):
@larsf no reason why hyperledger composer couldn't run on Red Hat so long as you can satisfy the pre-reqs. If you have any specific problems then you can raise issues or ask on RocketChat

@dselman DO you know any workarounds for issue https://github.com/hyperledger/composer/issues/1007

davidoevans (Mon, 19 Jun 2017 18:47:49 GMT):
I was able to create a participant using `composer` command line utility. However, when I try to issue an identity I get `Error: fabric-ca request register failed with errors [[{"code":400,"message":"Authorization failure"}]]`. In both cases, I was using the default uid/pw admin/adminpw.

davidoevans (Mon, 19 Jun 2017 18:48:45 GMT):
so I get my question is...what user is authorized to create identities by default or how do I create one?

davidoevans (Mon, 19 Jun 2017 18:50:12 GMT):
I'm using Composer v0.8 with Fabric-1.0.0-beta

Hi. I was able to finish the developer tutorial successfully and get my business network deployed to local instance of hyperledger fabric. Today I am trying to do the same again and suddenly I am getting an error I have not seen before. The error is pasted below

dselman (Mon, 19 Jun 2017 20:00:37 GMT):
Please search on StackOverflow using the hyperledger-composer tag. You will find many references to Bluemix. Composer can currently be deployed to Bluemix HLF 0.6 instances. There is not yet an IBM cloud offering that supports HLF v1beta1 (though it is in the works).

@davidkel

davidkel (Mon, 19 Jun 2017 21:10:43 GMT):
@emlorc01 what happens if you issue the command `nc localhost 7051` ? does it hang or does it return immediately ?

davidkel (Mon, 19 Jun 2017 21:12:08 GMT):
@davidoevans What is most likely is that you have at some point restarted the hyperledger fabric containers but you have an old enrollment of admin still in your keyValStore. This old enrollment is not valid for use with the CA any more which is why the issue identity fails when you try it with the userid 'admin'

davidoevans (Mon, 19 Jun 2017 21:14:11 GMT):
@davidkel if that's the case, should i not have gotten a similar error when issuing `composer participant add -p hlfv1 -n 'healthchain-network' -i admin -s adminpw ..` command?

davidoevans (Mon, 19 Jun 2017 21:14:37 GMT):
...or is that composer command not hitting fabric-ca?

davidkel (Mon, 19 Jun 2017 21:14:51 GMT):
@davidoevans that composer command doesn't contact the fabric-ca

davidoevans (Mon, 19 Jun 2017 21:15:45 GMT):
right...so do i need to teardownFabric and run everything from scratch?

davidkel (Mon, 19 Jun 2017 21:18:33 GMT):
@davidoevans that's one way, but if you do, you must delete the contents of the keyValStore directory (which is likely to be ~/.hfc-key-store) and then you will need to run createComposerProfile.sh as well. That will put the crypto material and userid definition for PeerAdmin into the KeyValStore for you.

davidoevans (Mon, 19 Jun 2017 21:21:39 GMT):
Thanks again @davidkel . Would it make sense to have a `ca-admin` id that is distinct from a `composer-admin` id?

davidoevans (Mon, 19 Jun 2017 21:28:45 GMT):
@davidkel that worked! thanks

davidkel (Mon, 19 Jun 2017 21:28:54 GMT):
@davidoevans There is an issue to look at what are called system acl's, see https://github.com/hyperledger/composer/issues/722 which I think covers what you are thinking

emlorc01 (Mon, 19 Jun 2017 21:42:44 GMT):
@davidkel when running nc localhost 7051 it hangs for a while, does not return

emlorc01 (Mon, 19 Jun 2017 21:43:06 GMT):
how do i replace the old enrollment with an updated one

davidkel (Mon, 19 Jun 2017 21:46:28 GMT):
@emlorc01 it hanging is what I would expect to happen. There are 2 ways, the easiest being to remove the ~/.hfc-key-store contents and run createComposerProfile.sh to effectively copy in the credentials for PeerAdmin back into that directory.

emlorc01 (Mon, 19 Jun 2017 21:50:31 GMT):
do i need to delete all the contents? there are are a priv and pub key in there

emlorc01 (Mon, 19 Jun 2017 21:50:35 GMT):
or just delete PeerAdmin

davidkel (Mon, 19 Jun 2017 21:58:25 GMT):
@emlorc01 You would delete all the contents and then run createComposerProfile.sh to re-add PeerAdmin back in

mattalhonte (Mon, 19 Jun 2017 23:50:18 GMT):

I edited my Model and made a new .bna file. The REST server registered the change (I added a new field), but when I go to the Angular app it doesn't reflect the new content. Anyone know why?

sstone1 (Tue, 20 Jun 2017 01:22:11 GMT):
@mattalhonte you need to re-run the Angular generator to generate updated components

mattalhonte (Tue, 20 Jun 2017 01:22:34 GMT):
Ah, k, thanks!

@dselman ok,i will try and push the docs

@mattalhonte what's with the `> >` at the start of each continuation line?

i can't see anything else wrong though, it looks OK to me

sstone1 (Tue, 20 Jun 2017 03:42:13 GMT):
@rohilsurana why do you need a workaround for that issue?

sstone1 (Tue, 20 Jun 2017 03:42:26 GMT):
it's not really a bug or defect, it's a user story to enable other functionality

rohilsurana (Tue, 20 Jun 2017 03:42:52 GMT):
@sstone1 sorry wrong link - https://github.com/hyperledger/composer/issues/1007

ah, that makes more sense :)

sstone1 (Tue, 20 Jun 2017 03:43:29 GMT):
there is no workaround at the moment

rohilsurana (Tue, 20 Jun 2017 03:43:51 GMT):
ok can I fail a transaction from transaction processor function?

sstone1 (Tue, 20 Jun 2017 03:43:52 GMT):
you can only access the identifier from a relationship

sstone1 (Tue, 20 Jun 2017 03:43:57 GMT):
yeah, just throw an error

mattalhonte (Tue, 20 Jun 2017 03:44:02 GMT):
It works now. Though before I copied and pasted what Explorer outputted.

sstone1 (Tue, 20 Jun 2017 03:44:08 GMT):
`throw new Error('abort transaction');`

sstone1 (Tue, 20 Jun 2017 03:44:19 GMT):
you can change the error text to whatever you like

rohilsurana (Tue, 20 Jun 2017 03:45:12 GMT):
That's perfect. Does the rest server process these errors and forward them?

sstone1 (Tue, 20 Jun 2017 03:45:29 GMT):
which version of Fabric are you using?

sstone1 (Tue, 20 Jun 2017 03:45:43 GMT):
for Fabric v1.0, you should get the error text from the Composer REST server.

sstone1 (Tue, 20 Jun 2017 03:45:46 GMT):
but not for Fabric v0.6.

rohilsurana (Tue, 20 Jun 2017 03:46:09 GMT):
yes I am using Fabric 1.0

rohilsurana (Tue, 20 Jun 2017 03:46:22 GMT):
also will the transaction be registred ?

sstone1 (Tue, 20 Jun 2017 03:46:37 GMT):
no, failed transactions cannot record anything on the Blockchain

sstone1 (Tue, 20 Jun 2017 03:46:46 GMT):
although you will see it in the Fabric logs

rohilsurana (Tue, 20 Jun 2017 03:48:22 GMT):
Ok I guess that doesn't matter to me right now. Thank for all the help.

sstone1 (Tue, 20 Jun 2017 03:48:47 GMT):

if you mean the dependency composer-connector-embedded : "latest" , so yes , and I did npm install to the network

If you've correctly installed v0.8 it should work (automation checks it).

@xuzhao103389 could you post your `docker ps` and `cat ~/.composer-connection-profiles/hlfv1/connection.json`. Was it working before and now has stopped working ? A connect failed implies something wrong either with the fabric itself or some docker network problem

davidkel (Tue, 20 Jun 2017 09:45:43 GMT):
@jaguarg I guess it has been working and has now stopped working with a `connect failed` ?

@xuzhao103389 you can see if there is a problem with the peer by running `docker logs peer0.org1.example.com` but I am wondering if there is some sort of docker network issue.

davidkel (Tue, 20 Jun 2017 09:54:49 GMT):
@jaguarg how much memory have you allocated to your vagrant environment ?

davidkel (Tue, 20 Jun 2017 09:58:26 GMT):
@Vipul_Bajaj Failure to load the connector sometimes means that the dependencies failed to build or you don't have enough memory. First thing to try is to uninstall and reinstall composer-cli and watch for any errors downloading dependencies or building native libraries which may fail.

xuanyue202 (Tue, 20 Jun 2017 12:20:07 GMT):
Hi, I think there is no inconsistency on Relationship between the doc and the actual implementation.

xuanyue202 (Tue, 20 Jun 2017 12:20:21 GMT):
In the doc, it reads "Relationships must be resolved to retrieve an instance of the object being referenced. The act of resolution may result in null, if the object no longer exists or the information in the relationship is invalid.", which looks good

xuanyue202 (Tue, 20 Jun 2017 12:22:40 GMT):
However, in the playground, if an invalid relationships in a Relationship of a Relationship as a transaction field, for example, will results in an failure of the transaction execution.

xuanyue202 (Tue, 20 Jun 2017 12:24:19 GMT):

Message Attachments

xuanyue202 (Tue, 20 Jun 2017 12:25:17 GMT):
for example, either missing owner, or any SampleAsset in assets array, will results in an exception during the transaction execution.

xuanyue202 (Tue, 20 Jun 2017 12:27:51 GMT):
since "Relationships are unidirectional and deletes do not cascade", this will make the Relationship management very hard. I think to leave the deleted relationships as null, just as stated in the doc, is a better solution.

dselman (Tue, 20 Jun 2017 12:30:53 GMT):
The runtime will resolve relationships in incoming transactions

dselman (Tue, 20 Jun 2017 12:31:35 GMT):
we could however leave them as null if they fail to resolve, rather than throwing an exception

dselman (Tue, 20 Jun 2017 12:31:36 GMT):
?

emlorc01 (Tue, 20 Jun 2017 12:35:42 GMT):
Error: error trying deploy. Error: error trying install chaincode. Error: Connect Failed Command failed

emlorc01 (Tue, 20 Jun 2017 12:36:08 GMT):
Also I tried again to run nc localhost 7051 again and it still hangs same as the first time

davidkel (Tue, 20 Jun 2017 12:37:41 GMT):
@emlorc01 so the only way I have been able to create that error is if I change my connection profile so the peer url info are pointing to the wrong ports. I have also seen docker networking get confused such that comms to docker containers stopped working and a reboot was required. If you do `sudo netstat -nlp` (assuming you are linux) what do you get ?

@emlorc01 could you set the following env `export GRPC_VERBOSITY=DEBUG` and try your deploy again

xuanyue202 (Tue, 20 Jun 2017 12:43:44 GMT):
I am not sure. But just use to take the sample as an example. 1. Create a sample asset and reference to a non-exist participant; 2. Submit a transaction specifying the created asset as argument. 3. an exception is thrown

davidkel (Tue, 20 Jun 2017 12:51:00 GMT):
@emlorc01 You are the 2nd person to show that localhost is trying to go via some sort of proxy which I don't understand.

davidkel (Tue, 20 Jun 2017 12:58:46 GMT):
@emlorc01 and we have now know the answer. localhost in your connection profile is causing a problem try replacing it with your specific ip address of your machine

emlorc01 (Tue, 20 Jun 2017 13:02:00 GMT):
ok great. yes i was just now setting no_proxy variable to localhost but that didnt seem to fix it.

emlorc01 (Tue, 20 Jun 2017 13:02:12 GMT):
to change the connection profile should i change it in the createComposerProfile.sh before running that script? or elsewhere?

emlorc01 (Tue, 20 Jun 2017 13:03:14 GMT):
or here composer-

emlorc01 (Tue, 20 Jun 2017 13:03:30 GMT):
~/.composer-connection-profiles/hlfv1/connection.json

davidkel (Tue, 20 Jun 2017 13:06:21 GMT):
@emlorc01 it needs to be changed in ~/.composer-connection-profiles/hlfv1/connection.json and you could change it in createConposerProfile.sh so that if you run that again in the future it will create hlfv1 again with your required info

emlorc01 (Tue, 20 Jun 2017 13:07:01 GMT):
ok it succeeded! awesome. thanks for the help!

emlorc01 (Tue, 20 Jun 2017 13:07:13 GMT):
i wonder what is reason that it wont recognize localhost, but changing all instances of localhost to my actual IP did the trick

davidkel (Tue, 20 Jun 2017 13:08:47 GMT):
Good question, be interested to know your exact environment you are in including whether you are running specific company images of operating systems

emlorc01 (Tue, 20 Jun 2017 13:11:42 GMT):
i'm honestly not sure, i will have to ask the guy who provisioned this server for me. it is ubuntu 16.04 but if i find out anything about the specific image i will let you know.

I click Import/Replace, pick the car auction network, and click Deploy. I then get an error of "Error: No connection found with ID d5c507d8-b9c9-455e-addd-c40e4ced2133". Am I doing something wrong? Or is this an instance of "In Hyperledger Fabric Beta peers now enforce the concepts of admins and members." seen in the "Installing and running Hyperledger Composer Playground locally" documentation? Thanks for any help or guidance. Update: OK, I thought I would try the "composer identity import" command from the tutorial, with appropriate paths, but I don't have the composer executable installed, which I guess makes sense since I'm running online! I then went back to the Test tab in the online composer, but now get "Error: No connection found with ID cb902121-36e6-43f4-93bd-add9cb2c3b15". So I guess I'm now really stuck. Any ideas? Thanks.

[ ](https://chat.hyperledger.org/channel/composer?msg=FGj7bL7wHrvsv7qKT) @Vipul_Bajaj if you followed the developer tutorial, the Docker network name is `composer_default`.

sstone1 (Tue, 20 Jun 2017 21:22:50 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=iWxNe8heZs2JgaQub) @Vipul_Bajaj `Dockerfile` is the name of the file, and it is a standard name that the `docker build` command looks for in order to build a new Docker image. The name `myorg/my-composer-rest-server` is the name that the tutorial gives to the custom Docker image that you are building as part of the tutorial.

sstone1 (Tue, 20 Jun 2017 21:24:05 GMT):
@gkd720 the error `Error: No connection found with ID d5c507d8-b9c9-455e-addd-c40e4ced2133` means that the backend part of the Composer Playground crashed and lost your connection to the Fabric; you can try refreshing the page which will force a reconnect, but if the problem persists please can you collect the output from Composer Playground? If you are using Docker then you will need to use `docker logs`.

sstone1 (Wed, 21 Jun 2017 01:44:57 GMT):
@davidoevans it looks like you are using an old version of the `composer-client` library to talk to a Fabric v1.0 beta

sstone1 (Wed, 21 Jun 2017 01:45:24 GMT):
can you check the level of the `composer-client` library? If you run a `npm ls --depth=0` in your Node.js application you should see it.

you are correct ``` ├── composer-admin@0.7.4 ├── composer-cli@0.7.4 ├── composer-client@0.7.4 ├── composer-connector-embedded@0.7.4 ├── composer-cucumber-steps@0.7.5 ```

Binay1 (Wed, 21 Jun 2017 02:20:58 GMT):
How do I deploy my composer application from the dev tutorial (https://hyperledger.github.io/composer/tutorials/developer-guide.html) on a cluster ? Just a few tweaks in the docker-compose.yml file or something else ?

sstone1 (Wed, 21 Jun 2017 02:27:36 GMT):
@Binay1 you need to deploy Hyperledger Fabric to the cluster, and then you can deploy a Composer business network to that Hyperledger Fabric instance.

sstone1 (Wed, 21 Jun 2017 02:28:23 GMT):
For questions on deploying Fabric to a cluster, ask in #fabric - there is some work being done on building Kubernetes configuration files for Fabric which might be of interest. Otherwise you will need to use a Docker technology like Docker Swarm.

Binay1 (Wed, 21 Jun 2017 02:35:07 GMT):
@sstone1 Thank you

i read the chat about ACL rule. and wonder the rule is implemented by fabric or composer?

sstone1 (Wed, 21 Jun 2017 02:37:53 GMT):
The ACL rules on assets and participants are implemented in Composer

sstone1 (Wed, 21 Jun 2017 02:38:21 GMT):
The ACL rules protect access to data stored in the world state

bh4rtp (Wed, 21 Jun 2017 02:40:19 GMT):
thanks. does this mean composer function more than building up the network but also access control and other things?

sstone1 (Wed, 21 Jun 2017 02:41:19 GMT):
yes - Composer lets you define the structure of the data in the network, define who can access which assets, and define your business logic

bh4rtp (Wed, 21 Jun 2017 02:42:38 GMT):
that is interesting. i have been suggesting fabric should add access control and find this implementation in composer.

sstone1 (Wed, 21 Jun 2017 02:43:05 GMT):
smart contracts usually control access to the data that they manage

bh4rtp (Wed, 21 Jun 2017 02:43:43 GMT):
yes. thanks.

bh4rtp (Wed, 21 Jun 2017 02:49:24 GMT):
@sstone1 as for ACL rules, it is very useful to make the fabric network secure. would you please inform us more details about it? i think it is implemented through chaincode by getCreator, isn't it?

Hi, I'd like to add an Insurer participant to the Vehicle Lifecycle sample. I'm happy to have a go at contributing the code/models. I don't have much (any) experience of writing Composer models/code so would appreciate some guidance. I've raised https://github.com/hyperledger/composer/issues/1341 to cover the work, and added a comment with my thoughts on what's required in terms of model changes, including a couple of questions. Any comments would be very welcome. Thanks.

I'm not sure if it's necessary to maintain the bidirectional relationships between Company and Locations or if it would be enough to simply have a reference to Company from a Location and would that support getting a list of locations for a given company.

@davidoevans makes sense to me. Having the bidirectional relationship may make it easier to code against -- otherwise you will need to run a complex query everytime you want to find all locations for a company.

@Vipul_Bajaj either stop what is already using port 3000 or use a different port (i.e. `-p 3001:3000`)

davidoevans (Wed, 21 Jun 2017 13:58:42 GMT):
@Vipul_Bajaj the rest server uses port 3000 by default...and it seems whatever else you were running was also trying to use port 3000. if that's correct, you just need to make sure one of those processes is using a different port.

torresjeff (Wed, 21 Jun 2017 14:29:30 GMT):
When issuing an identity to a participant, can it have special characters?

JennFoley (Wed, 21 Jun 2017 14:59:31 GMT):
Two questions after playing with the new Composer Playground running on Bluemix. 1) When I uploaded a .bna file from the older version of Composer, it mentioned needing to not have any caps in the filename. Any chance that could be handled in code (so people don't have to use an editor and guess where all the name is.)? 2) When going to import a file, it now asks to authenticate with GitHub to get the samples, could it ever authenticate with our own repository on GitHub to get files and export to GitHub?

JennFoley (Wed, 21 Jun 2017 15:03:48 GMT):
Also, this might be a silly question, if I modify a sample to make my own code in the Playground, how can I edit the README.md? Text Editor?

rjrutkow (Wed, 21 Jun 2017 15:41:16 GMT):
Hi, has anyone successfully created a connection profile for connecting to a blockchain v1.0 Beta service yet on a cloud platform (like bluemix)? I tried reading the docs on the composer website but the differences between connection profiles for v1.0 alpha and v1.0 beta are unclear

dselman (Wed, 21 Jun 2017 15:42:04 GMT):
@JennFoley 1. Not sure I understand -- but this restriction comes from Fabric. In version 0.8 of Composer we now enforce this restriction.

dselman (Wed, 21 Jun 2017 15:42:39 GMT):
2. This a GitHub API restriction. We are considering moving the samples off GitHub to workaround this.

dselman (Wed, 21 Jun 2017 15:43:03 GMT):
3. Yes, you have to edit the README externally and then upload.

JennFoley (Wed, 21 Jun 2017 15:44:32 GMT):
Hi @dselman, 1. Basically on the Import/Replace when it must do some kind of check for capital letters, could it not also do something like change to lowercase (programmatically) instead of giving the error message?

dselman (Wed, 21 Jun 2017 15:45:19 GMT):
We considered this, but it creates more confusion later, when you want to connect to the network, list it, connect etc.

JennFoley (Wed, 21 Jun 2017 15:45:39 GMT):
ah, okay.

dselman (Wed, 21 Jun 2017 15:45:46 GMT):
We felt it was better to impose some short term pain to align with Fabric... Sorry!

JennFoley (Wed, 21 Jun 2017 15:46:24 GMT):
lol. No worries. I am hoping things are still early enough, this won't be a widespread problem with endusers

Hi, is the composer-atom-plugin available for unbuntu? I've managed to install it in Atom on Windows, but it's not showing up when I search in Atom on Ubuntu.

rjrutkow (Wed, 21 Jun 2017 15:56:12 GMT):
Are there any documents available for walking through the deployment steps on composer for v1.0 Beta?

dselman (Wed, 21 Jun 2017 16:15:20 GMT):
@GrahamCharters I don't know why it would not be, but I've not tried personally. The VSCode extension is much more powerful (does a full parse of the model files, not just syntax highlighting).

GrahamCharters (Wed, 21 Jun 2017 16:17:09 GMT):
Thanks, @dselman . I'm gonna try the command line approach and if that doesn't work, I may give VSCode a try.

dselman (Wed, 21 Jun 2017 16:17:30 GMT):
It's very nice, once you get used to it.

GrahamCharters (Wed, 21 Jun 2017 16:18:53 GMT):
Command line worked. I may still try VSCode as your sales pitch is compelling ;)

dselman (Wed, 21 Jun 2017 16:22:16 GMT):
If you create a lot of model files, it catches a lot of problems early.

IBM does not yet host HLF v1-beta1 in the cloud.

You will have to wait for the IBM cloud to support it.

wael (Thu, 22 Jun 2017 06:29:57 GMT):
you can try it also at playground

davidkel (Thu, 22 Jun 2017 07:25:03 GMT):
@lbennett I suspect you are using the alpha1 release of the Hyperledger Fabric rather than the beta release. If you do `docker ps` you can see what version it is. Composer v0.8.0 is only compatible with hyperledger fabric 1.0 beta release.

Pere-Lluis (Thu, 22 Jun 2017 07:32:00 GMT):
@davidkel Yes I know, I'm running the new beta of Fabric. Should I be using something else?

Pere-Lluis (Thu, 22 Jun 2017 07:32:39 GMT):
beta, not the alpha

davidkel (Thu, 22 Jun 2017 07:34:24 GMT):
@Pere-Lluis The version of the createComposerProfile.sh you posted was from the alpha version of the dev server package which is why I asked

Pere-Lluis (Thu, 22 Jun 2017 07:35:00 GMT):
yeah, you're right I see it to, but the docker files were from the beta

Pere-Lluis (Thu, 22 Jun 2017 07:35:25 GMT):
I took the createComposerProfile from a past version, do you know where I can get the newest one?

Pere-Lluis (Thu, 22 Jun 2017 07:35:25 GMT):
but that's from composer right?

davidkel (Thu, 22 Jun 2017 07:36:53 GMT):
I would recommend downloading the latest fabric-dev-server using curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.tar.gz

davidkel (Thu, 22 Jun 2017 07:37:38 GMT):
this will have setup scripts to make it easier to work with Hyperledger fabric beta as they have introduced a new security model.

davidkel (Thu, 22 Jun 2017 07:38:59 GMT):
more info can be found at https://hyperledger.github.io/composer/installing/development-tools.html Around the middle of the page (and ignore the mistake at the top still referring to alpha :-) )

Pere-Lluis (Thu, 22 Jun 2017 07:39:38 GMT):
I mean that's from composer with premade crypto files and channel artifacts right?

Pere-Lluis (Thu, 22 Jun 2017 07:39:54 GMT):
if you want to create your own nodes etcetera are u able with this?

https://hyperledger.github.io/composer/installing/development-tools.html

davidkel (Thu, 22 Jun 2017 07:53:21 GMT):
@Pere-Lluis if you are going to go down the path of trying to set up your own fabric, then we will work with that setup, but you are going to have to use composer identity import to import the peer admin crypto material into your profile KeyValStore directory, before you can deploy to that peer. How you then choose to define your fabric and generate the required crypto material is up to you. Cryptogen is a dev/test tool provided by Hyperledger fabric but would not be used in production

Pere-Lluis (Thu, 22 Jun 2017 07:54:09 GMT):
oh I see, so you think is too ambicious to try to make your own?

Pere-Lluis (Thu, 22 Jun 2017 07:54:33 GMT):

do you have any tips on what to follow? Cause all tutorials I see for Fabric are based on a given example with just two peers, and I'm struggling trying to set my own peers and nodes in different terminals

Pere-Lluis (Thu, 22 Jun 2017 07:56:56 GMT):
and by the way, thank you for the help, without it I would be lost (although I must say the Composer docs are very well explained)

davidkel (Thu, 22 Jun 2017 07:58:43 GMT):
@Pere-Lluis I wouldn't say too ambitious but certainly not trivial and I think that there is still more work needed by fabric on the documentation front to help people understand the requirements needed for creating a deployment of a production fabric environment

davidkel (Thu, 22 Jun 2017 08:00:28 GMT):
@Pere-Lluis I'm still trying to get to grips with it all too :-) Some of the ways I gather information is to review past posts on the #fabric, #fabric-questions and other channels as lots of useful information does get put there

davidkel (Thu, 22 Jun 2017 08:01:48 GMT):
@Pere-Lluis Thanks for the complement about our documentation as a lot of good work went in to try to make it as helpful as possible.

Pere-Lluis (Thu, 22 Jun 2017 08:06:27 GMT):

Pere-Lluis (Thu, 22 Jun 2017 08:09:09 GMT):
so, in order to get things right, what would u recommend I use for a 200 users network, is there any fabric premade instance I could use?

Pere-Lluis (Thu, 22 Jun 2017 08:09:51 GMT):
Or should I try to modify the existing one ( like the one u shared of dev-tools )

davidkel (Thu, 22 Jun 2017 08:15:44 GMT):
@Pere-Lluis Ours is really only meant as a development environment and nothing more. I not really in a position to provide guidance on how to set up a production fabric you would need to try other channels to see if you can get help there. Alternatively you could look at service providers such as IBM bluemix to provide the necessary infrastructure.

Pere-Lluis (Thu, 22 Jun 2017 08:16:16 GMT):
sure, thanks

Pere-Lluis (Thu, 22 Jun 2017 08:16:41 GMT):
Yeah, I check IBM but they were a bit back in versions

Pere-Lluis (Thu, 22 Jun 2017 08:17:05 GMT):

thanks @davidkel it was a composer profile problem

Pere-Lluis (Thu, 22 Jun 2017 08:19:12 GMT):
solved, worked like a charm

sstone1 (Thu, 22 Jun 2017 08:25:16 GMT):
@rohilsurana you should be issuing Blockchain identities to each user of the REST API. Each Blockchain identity should be issued to a participant instance, stored in a participant registry, that represents that user. Composer looks up the participant instance using the Blockchain identity when you submit transactions using the REST API, and uses the participant instance to perform ACL checks.

sstone1 (Thu, 22 Jun 2017 08:25:35 GMT):
You can also get "the current participant" from a transaction processor function using `getCurrentParticipant()`

rohilsurana (Thu, 22 Jun 2017 08:27:19 GMT):
@sstone1 Ok, but thats for the backend, I was thinking of showing the username and display picture on the frontend.

sstone1 (Thu, 22 Jun 2017 08:27:46 GMT):
oh! that i don't have answer for

sstone1 (Thu, 22 Jun 2017 08:27:55 GMT):
we don't expose the user information from passport

sstone1 (Thu, 22 Jun 2017 08:28:32 GMT):
you could always use the `/api/system/ping` which returns the current participant instance ID, and then you can get the participant instance from the participant registry

sstone1 (Thu, 22 Jun 2017 08:28:45 GMT):
so you could find the org.acme.Person that is logged in and show their name

rohilsurana (Thu, 22 Jun 2017 08:29:56 GMT):
That will be the default one set at the moment? I guess I will go with this approach.

sstone1 (Thu, 22 Jun 2017 08:44:04 GMT):
it will be `null` when you add the Blockchain identity `admin` or `PeerAdmin` to your wallet

sstone1 (Thu, 22 Jun 2017 08:44:27 GMT):
it will only be set when you use a Blockchain identity that you have issued using `composer identity issue` (or the relevant APIs)

hey, me again! Has anyone succeeding in Outh with Google?

stormli (Thu, 22 Jun 2017 09:14:49 GMT):
@davidkel Thanks for your explanation about why the response of GET transaction by ID is defined as an object without any properties. if I understand correctly, there are many kinds of transaction which has different definition. for each GET by id. it may return different kind of transaction. So there is no way to define a structure in swagger for it. right? after user get this response, I am wondering how consumer knows the type of the transaction? and where they can get definition to parse the response?

stormli (Thu, 22 Jun 2017 09:18:08 GMT):
anyone else know the answer of this question? thanks.

did that happen to you ?

Pere-Lluis (Thu, 22 Jun 2017 09:28:34 GMT):
I'm using passport-google-oauth

rohilsurana (Thu, 22 Jun 2017 09:28:48 GMT):
That is because you haven;t enabled the API from developer console

dselman (Thu, 22 Jun 2017 09:29:02 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=6ci2wY6bTmHaEdPy4) @stormli You can use the $class property on the returned object to get it's type, and from there you'll know the properties

hi, can I implement custom 'query' function on composer? in my understanding, transaction procressor is 'invoke' and cannot return data　 synchronously. how i add query logic after getting Assets?

rama_rahul (Thu, 22 Jun 2017 09:34:19 GMT):
I am developing an application and am following this link : https://hyperledger.github.io/composer/tutorials/developer-guide.html . I did everything according to this link but when I am submitting a transaction in the rest server it is showing error response code 500. It was being submitted properly in the playground but if I try to submit it through the rest server it is giving error. Mostly where is the problem?

Pere-Lluis (Thu, 22 Jun 2017 09:34:43 GMT):
@rohilsurana I think i0ve done that

Pere-Lluis (Thu, 22 Jun 2017 09:34:49 GMT):
to obtain the keys right?

Pere-Lluis (Thu, 22 Jun 2017 09:37:55 GMT):
but still same problem

Pere-Lluis (Thu, 22 Jun 2017 09:40:24 GMT):
@rohilsurana you mean the google+ api right? There's no Google+ login Api

stormli (Thu, 22 Jun 2017 10:06:11 GMT):
@dselman Do you mean there will be a $class string in response, then user could find a definition in swagger that can map to that $class?

stormli (Thu, 22 Jun 2017 10:06:49 GMT):
eg org.vda.VehicleTransferLogEntry is a class of transaction?

rohilsurana (Thu, 22 Jun 2017 10:09:47 GMT):
@Pere-Lluis also have you added scope: ["profile"] in the providers JSON

@stormli I mean that if you GET transaction with ID xyz you will received a JSON response. That response will contain a top-level $class attribute, which is the fully qualified name of the Composer modelled type.

How can we use passport-oauth-client-password strategy with Composer REST server

dselman (Thu, 22 Jun 2017 10:35:55 GMT):
@stormli I'm curious to know what you plan to do on the client side...

dselman (Thu, 22 Jun 2017 10:38:49 GMT):
@Vipul_Bajaj various people (e.g @Pere-Lluis) have been able to use the Composer REST Server with passport.js auth. I think I've seen LDAP, Twitter, GitHub and Google ids being used... Given that there are 300+ passport plugins we can't provide support on all of them. If you get stuck using a given passport implementation probably the best bet is to use the passport support forums. We are pretty confident at this stage that the Composer usage of passport is correct... Of course any issues/questions that DO look specific to Composer should go to StackOverflow.

Pere-Lluis (Thu, 22 Jun 2017 10:42:57 GMT):
@Vipul_Bajaj also if you have a more specific question you can ask me directly if you want

Pere-Lluis (Thu, 22 Jun 2017 10:43:48 GMT):
By the way, after setting the Oauth, if you want it to associate that user with a Blockchain identity/participant it has to have been added beforehand right?

Pere-Lluis (Thu, 22 Jun 2017 10:44:18 GMT):
and you have to manually associate that account to the user by the wallet giiving the userid and secret?

Pere-Lluis (Thu, 22 Jun 2017 10:45:10 GMT):
I ask in case there's a way that once you OAuth authenticate, a participant and blockchain profile with that account can be issued authomatically?

zgalvin111 (Thu, 22 Jun 2017 10:48:04 GMT):
How do you write a function in composer that requires two parties to confirm a transaction? So a transaction cannot go through without the confirmation of both parties?

Pere-Lluis (Thu, 22 Jun 2017 11:00:50 GMT):
I will reformulate the question since it's a bit confusing:

dselman (Thu, 22 Jun 2017 11:01:20 GMT):
@zgalvin111 this is a pretty big question.. probably best to post to StackOverflow

Pere-Lluis (Thu, 22 Jun 2017 11:01:40 GMT):
Can you issue a Participant in the RestAPI in order to create a user/trader for it automatically for a user that has OAuth login?

Pere-Lluis (Thu, 22 Jun 2017 11:01:54 GMT):
or does it have to be previously issued?

zgalvin111 (Thu, 22 Jun 2017 11:03:08 GMT):
@dselman Ok, thank you. Also, what is the best way to take a business network developed in playground to a test network?

Pere-Lluis (Thu, 22 Jun 2017 11:10:42 GMT):
@zgalvin111 try to start a Fabric instance with this https://hyperledger.github.io/composer/installing/development-tools.html

Pere-Lluis (Thu, 22 Jun 2017 11:10:50 GMT):
and then deploy your .bna

Pere-Lluis (Thu, 22 Jun 2017 11:11:17 GMT):
https://hyperledger.github.io/composer/business-network/bnd-deploy.html

Pere-Lluis (Thu, 22 Jun 2017 11:13:16 GMT):
To sum up, is it possible to have "First, you must issue a Blockchain identity to a participant in the business network. This example will assume that you have issued the Blockchain identity alice1 to the participant org.acme.mynetwork.Trader#alice@email.com, and the secret is suchs3cret." this part done automaticaly every time a new user logins with Oauth?

zgalvin111 (Thu, 22 Jun 2017 11:14:05 GMT):
@Pere-Lluis Awesome! Can you do that on Windows? Windows wasn't one of the platforms that was listed as required

Pere-Lluis (Thu, 22 Jun 2017 11:14:33 GMT):
well everything works through docker so should be alright

Pere-Lluis (Thu, 22 Jun 2017 11:14:43 GMT):
can't promise anything do, I'm with Linux

Pere-Lluis (Thu, 22 Jun 2017 11:14:55 GMT):
it's probably advisable to use a Virtual Machine with linux

Regarding the whole conversation about identity above, could you give me a short update on the current status of integration of the rest server with passport or a good pattern to combine loopback / passport logins with the composer loopback component?

sstone1 (Thu, 22 Jun 2017 12:05:36 GMT):
@Pere-Lluis there is no way to do what you describe above - automatically issue identities for users when they log in to the Composer REST server. There's two steps that would need to be added - automatically adding a participant and mapping the users OAuth profile data (or whatever) into the participant data - and then issuing the new participant with an identity to use.

sstone1 (Thu, 22 Jun 2017 12:05:46 GMT):
... at the moment that is ...

@zgalvin111 Composer doesn't do anything with channels. When to deploy a business network your connection profile specifies the channel you want to deploy it to.

@davidkel the `SyntaxError: Unexpected token (19:16)` is probably the bit I should have posted here. I wasn't sure what it was referencing until I pasted the js into the playground and it spat out the same error

zgalvin111 (Thu, 22 Jun 2017 14:36:18 GMT):
@davidkel Ok, so if you wanted to effectively have different channels in composer, you would have to create multiple BNA's or permission your network in such a way that it works. Am I understanding it right?

davidkel (Thu, 22 Jun 2017 14:38:33 GMT):
@zgalvin111 You would configure your fabric with whatever channels you needed. Channels have their own ledger and world state and are not shared across channels.

@zgalvin111 You would configure your fabric with whatever channels you needed. Channels have their own ledger and world state and are not shared

davidkel (Thu, 22 Jun 2017 14:40:09 GMT):
@zgalvin111 So when you deploy a business network to a channel you are providing that business network with the ledger and world state it will use

zgalvin111 (Thu, 22 Jun 2017 14:41:49 GMT):
Right. Ok, just so I understand, each business network requires one ledger and world state? You couldn't have multiple business networks on one ledger. Right?

davidkel (Thu, 22 Jun 2017 14:44:24 GMT):
You can have multiple business networks deployed to the same channel so they will share the ledger and world state. I don't think anyone has investigated whether it's possible to access data from another business network

zgalvin111 (Thu, 22 Jun 2017 14:49:16 GMT):
Yeah, I would assume that is somewhat of a security risk but I have no idea.

JohnWhitton (Thu, 22 Jun 2017 14:59:51 GMT):

@sstone1 I tried refreshing by just rerunning `composer.sh` and that did the trick. I may have waited too long after playing with the sampleAsset/sampleParticipant example, and maybe lost the connection to the fabric like you mentioned. I'll noe step through the car auction example. Thanks. @davidkel Fortunately it looked like something simple. Thanks. *Update* I retried things, and was able to import/deploy the car auction network 0.0.9. But clicking the Test tab got an error (couldn't find connectionID or something like that). So I reran `composer.sh`, imported car auction, and clicked Test. I am now able to make new members, vehicles, etc. So it looks like there is some kind of short timeout occurring, like maybe a minute or two. Is this expected? What are the timeout values? Can I extend? (I guess I don't work too quick!) Thanks.

we are really having a hard time trying to deploy Composer into Bluemix 0.6 or Bluemix 1.0 For Bluemix 0.6 we are using the following connection profile https://github.com/plucena/hyperledger/blob/master/composer/connection.json and most of times we get connection errors such as those ones bellow: events.js:160 throw er; // Unhandled 'error' event ^ Error: {"created":"@1498151112.701000182","description":"EOF","file":"../src/core/lib/iomgr/tcp_posix.c","file_line":235,"grpc_status":14} at ClientDuplexStream._emitStatusIfDone (/usr/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:189:19) at ClientDuplexStream._receiveStatus (/usr/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:169:8) at /usr/lib/node_modules/composer-cli/node_modules/grpc/src/node/src/client.js:634:14 We believe that connecting composer to Bluemix is an essential step, but I didn't get much help from the Rocket.chat community. @Yao were you able to have a successful deploy on Bluemix for 0.6 or 1.0 ?

davidkel (Thu, 22 Jun 2017 17:31:45 GMT):
@lbennett also check stack overflow as hopefully some of the common pitfalls are there under the `hyperledger-composer` tag

lbennett (Thu, 22 Jun 2017 17:32:11 GMT):
thank you!

davidkel (Thu, 22 Jun 2017 17:33:04 GMT):
@Percival Lucena you could be hitting the event drop problem that bluemix has

silliman (Thu, 22 Jun 2017 17:50:22 GMT):
will the 'breaking changes' coming with Composer 0.9.x break everybody who is using 0.8.x or just if you have used certain functions/features that have changed. I guess what I'm asking is, if I am using, e.g., the digitalproperty-app from composer-sample-applications, will I still be able to use in 0.9.x what I've currently git clone'd now?

JennFoley (Thu, 22 Jun 2017 18:05:58 GMT):
also, (sorta goes with @silliman's question) because of the change to Composer 0.8.x where I had to conform to the fabric naming standard for the project, is it to be expected that on redeploy, I would lose all of my existing data in blockchain?

sstone1 (Thu, 22 Jun 2017 19:03:38 GMT):
@silliman the breaking changes will break most people I suspect. model file and ACL file changes will be required everywhere, including to the sample applications.

sstone1 (Thu, 22 Jun 2017 19:03:54 GMT):
the biggest pain will be the removal of TX IDs and timestamps from the model files.

sstone1 (Thu, 22 Jun 2017 19:04:19 GMT):
it's less likely people will be using events (since it is newer), but the event IDs and timestamps will also need to be removed

sstone1 (Thu, 22 Jun 2017 19:04:29 GMT):
and then ACL files which use namespaces will also change

sstone1 (Thu, 22 Jun 2017 19:04:46 GMT):
i doubt that many people have used the `queryNative` function yet, but it'll be disappearing as well

silliman (Thu, 22 Jun 2017 19:04:53 GMT):
will you be synching the updates via npm with the GitHub updates for the sample applications?

sstone1 (Thu, 22 Jun 2017 19:36:07 GMT):
yeah

sstone1 (Thu, 22 Jun 2017 19:37:41 GMT):
@JennFoley yeah - we use the business network name for the chaincode ID, so you would have had a new chaincode ID created. data is lost when you create a new chaincode ID.

sstone1 (Thu, 22 Jun 2017 19:38:04 GMT):
we also do not support chaincode upgrade at the moment, which is required to upgrade the chaincode version of Composer - that's something we're considering.

sstone1 (Thu, 22 Jun 2017 19:38:19 GMT):
but you can do a business network update which will replace the BNA on the Blockchain side and keep all of your data

jmcnevin (Thu, 22 Jun 2017 19:41:26 GMT):
is there somewhere where I can get an overview of what happens when you deploy a BNA?

sstone1 (Thu, 22 Jun 2017 19:45:28 GMT):
I'm not sure we have any docs on that yet

sstone1 (Thu, 22 Jun 2017 19:45:37 GMT):
let me look... I'm sure we did some slides for it a while ago

sstone1 (Thu, 22 Jun 2017 19:48:09 GMT):
@jmcnevin if you write it up as a SO question (using the `hyperledger-composer` tag we can get it answered for you

sstone1 (Thu, 22 Jun 2017 19:48:19 GMT):
the slides we have on this are incomplete and seriously out of date

sstone1 (Thu, 22 Jun 2017 19:48:25 GMT):
an area we need to improve the docs for

silliman (Thu, 22 Jun 2017 19:48:52 GMT):
@sstone1 Hi Simon, do you think that if I qualified my global installs of composer-cli, composer-rest-server, composer-playgrond, generator-hyperledger-composer to specify @0.8.1, and made my own fork of composer-sample-applications from GitHub now, that I could stay in business for a little while against 0.8.1. I guess a lot of that depends on how the composer-related dependencies are specified in the packages.json files.

jmcnevin (Thu, 22 Jun 2017 19:49:08 GMT):
@sstone1 will do :)

sstone1 (Thu, 22 Jun 2017 19:50:12 GMT):
@silliman you should be fine with that - the dependencies are such that if you install cli@0.8.1, then you'll get 0.8.* of the dependencies

sstone1 (Thu, 22 Jun 2017 19:50:19 GMT):
it won't pull in 0.9.* dependencies

sstone1 (Thu, 22 Jun 2017 19:50:37 GMT):
the sample apps repo won't change... it will be the sample networks repo that will

sstone1 (Thu, 22 Jun 2017 19:50:44 GMT):
which is where the playground sample import loads them from

silliman (Thu, 22 Jun 2017 19:52:40 GMT):
@sstone1 hmm so I am not cloning sample-networks.....just sample-applications.. would this mean that the composer playground at 0.8.x will stay smart enough to get the right sample-networks after 0.9.x comes out?

sstone1 (Thu, 22 Jun 2017 19:53:01 GMT):
no - it pulls the sample networks straight from github

sstone1 (Thu, 22 Jun 2017 19:53:05 GMT):
which is broken!!!

sstone1 (Thu, 22 Jun 2017 19:53:09 GMT):
we need to fix that

sstone1 (Thu, 22 Jun 2017 19:53:27 GMT):
you may just need to export the ones you care about as BNA files and import them from disk

silliman (Thu, 22 Jun 2017 19:53:48 GMT):
is broken now? or do you mean broken against 0.9.x code

sstone1 (Thu, 22 Jun 2017 19:54:08 GMT):
i mean the system where playground pulls from github is broken

sstone1 (Thu, 22 Jun 2017 19:54:16 GMT):
and we should do something better that doesn't cause this problem

silliman (Thu, 22 Jun 2017 19:54:36 GMT):
is that the old GitHub Rate Limit exceeded thing or something else?

sstone1 (Thu, 22 Jun 2017 20:19:27 GMT):
it's more that we'd like to remove the need for GitHub authentication at all

sstone1 (Thu, 22 Jun 2017 20:19:46 GMT):
it's not great that you need a GitHub ID to import samples before you've even written a line of code with Composer

CT123 (Thu, 22 Jun 2017 21:17:02 GMT):
Was working with playground online using car auction and the "old" overview from the tutorial is missing - the docs in the test suite do not match the test code. For example, readme.md staes:"Switch to the Test tab, then click on the User participant registry, then click on the Create Participant button to create a new instance of a user." But there is NO "user" in test - only "member" and "auctioneer". Also, a couple of lines down readme states, "You now need to issue an identity card for this participant. Click the green ID card icon to the right of your participant. " But there is no 'greed id card icon' in the current .10 test suite. Can someone please advise or point me to the original car auction docs as I'm trying to model a new test suite against what I was using just a day ago. Thanks in advance!

dselman (Thu, 22 Jun 2017 21:20:27 GMT):
Sorry, the README is out of date -- we need to update that. The new tutorial is here: https://hyperledger.github.io/composer/tutorials/playground-guide.html

CT123 (Thu, 22 Jun 2017 21:25:50 GMT):
@dselman thanks but I need the *old* tutorial not the new one, the new one is a commodity trading network - I need the docs for the car auction network.... thanks.

CT123 (Thu, 22 Jun 2017 22:07:08 GMT):
@dselman update - pulled what I needed out of google webcache for the git -- thanks for responding!

MeenakshiSingh (Fri, 23 Jun 2017 00:05:16 GMT):
Hi...can we do fabric specific configurations like setting the consensus protocol or number of transactions which a block can contain through composer in a dev setup

rama_rahul (Fri, 23 Jun 2017 05:44:44 GMT):
Hi, I previously had composer version as 0.7.4. Since I was getting error while deploying my network I tried to upgrade it to 0.8.0 or above. For that I ran prereqs-ubuntu.sh given in this link : https://hyperledger.github.io/composer/installing/development-tools.html . But instead of upgrading now my composer version became 0.7.3. Someone please tell me how to upgrade it to 0.8.0

davidkel (Fri, 23 Jun 2017 06:19:11 GMT):
@rama_rahul to upgrade composer-cli, recommended way is to do `npm uninstall -g composer-cli && npm install -g composer-cli`. Do similar action for the composer rest server. If you have docker images you can pull the latest images. V0.8.0 will require the latest fabric-dev-server. The pre-reqs-ubuntu.sh is only a simple script to install certain prereq tools such as docker, docker-compose onto a ubuntu system it doesn't do anything with composer. Please ensure you have docker version 17.03 or later as it is now mandatory

davidkel (Fri, 23 Jun 2017 06:45:08 GMT):
@rama_rahul first do `npm uninstall -g composer-cli` and check you don't have any other versions installed by trying to run `composer -v` again. It's possible you still have old versions installed and you need to locate them and uninstall them as well.

sstone1 (Fri, 23 Jun 2017 06:58:17 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=hXSFWQigcSuDfKsFL) @MeenakshiSingh Composer is not a Fabric configuration/management tool; it includes a sample Fabric dev setup for getting going quickly with Composer, but it will deploy to any instance of Fabric that you configure.

Pere-Lluis (Fri, 23 Jun 2017 08:10:23 GMT):
I have a bit of a conceptual question

Pere-Lluis (Fri, 23 Jun 2017 08:11:17 GMT):
When you sue the development environment, and you deploy your chaincode on fabric, you can interact with it using with the RestAPI

Pere-Lluis (Fri, 23 Jun 2017 08:11:38 GMT):
provided a connection profile, that it's tied to the peers etcetera

Pere-Lluis (Fri, 23 Jun 2017 08:12:17 GMT):
but when your run local playground, aren't you doing the same? You provide a connection profile to it and it uses the fabric you have instanciated

Pere-Lluis (Fri, 23 Jun 2017 08:12:55 GMT):
So, I have deployed the chaincode on the dev-servers, and started the rest api

Pere-Lluis (Fri, 23 Jun 2017 08:13:08 GMT):
and at the same time, I'm running local playground

Pere-Lluis (Fri, 23 Jun 2017 08:13:50 GMT):
are they somehow related? Can you connect to the deployed chaincode through playground instead of though the restAPI?

Pere-Lluis (Fri, 23 Jun 2017 08:14:35 GMT):
or viceversa?

sstone1 (Fri, 23 Jun 2017 08:16:18 GMT):
you should be able to use multiple Composer clients (playground, REST API, etc) to connect to the same business network running on the same Fabric

sstone1 (Fri, 23 Jun 2017 08:16:38 GMT):
_however_ playground can only work a business network called `org-acme-biznet`

sstone1 (Fri, 23 Jun 2017 08:16:57 GMT):
so if you deploy a business network with a different name using the CLI or the APIs, rather than playground, playground won't be able to communicate with it

sstone1 (Fri, 23 Jun 2017 08:19:09 GMT):
we have some work lined up to fix that - that is the "cards" designs that Ed talked about yesterday on the call

Pere-Lluis (Fri, 23 Jun 2017 08:21:08 GMT):
yeah I just realized it was the name that confussed me

Pere-Lluis (Fri, 23 Jun 2017 08:21:18 GMT):
this gives cards much more sense

Pere-Lluis (Fri, 23 Jun 2017 08:21:41 GMT):
I see the chaincodes name is unchanged (as org...)

Pere-Lluis (Fri, 23 Jun 2017 08:21:48 GMT):
but it has my chaincode

Pere-Lluis (Fri, 23 Jun 2017 08:22:08 GMT):
so I'm running two equal chaincodes on the same network

Pere-Lluis (Fri, 23 Jun 2017 08:22:19 GMT):
thanks!

Pere-Lluis (Fri, 23 Jun 2017 08:25:43 GMT):
So when you connect to playground, you will always be able to interact as Admin there? In a sense that if someone else goes to playgrounds addres they will be using same wallet there or is it local?

Pere-Lluis (Fri, 23 Jun 2017 08:26:15 GMT):
(If you think this questions belong better to Stack Overflow, say so and I will post them there)

sstone1 (Fri, 23 Jun 2017 08:29:09 GMT):
that one needs a bit of explaining, so lets make that a SO one

Pere-Lluis (Fri, 23 Jun 2017 08:30:36 GMT):

dselman (Fri, 23 Jun 2017 09:42:16 GMT):
Yes, I've seen that as well -- there's a bug in there somewhere, maybe timing related Fabric is still coming up when Playground tries to deploy) or related to the state of local storage. If anyone can reproduce consistently I'd love to learn more.

Hi, any advice highly appreciated: We have Composer 0.8 and Fabric 1, and all the other pre-reqs up to date running on Ubuntu 16.04 in VMWare (on Win 10). We moved the image from a computer to another (copying the VMDK ++ files) and started Ubuntu on the target. So far working fine. However, whan running composer network deploy (we are now testing with the training network called "my-network", the composer network deploy fails with a "Connection Failed" error. No further details. I have tried several things link removing the docker containers (not the image), and turned off IPv6. Still the same problem. Also I have inspected the .composer-connection-profiles/hlfv1/connection.json file, it looks ok to me and are exactly the same as on the source ubuntu. So, why is this happening. When I started VMWare for the first time I selected "I moved it". Please anybody advice.

larsf (Fri, 23 Jun 2017 10:56:45 GMT):
Oh, I forgot to mention that the target ubuntu is placed in a red-zone, so no internet access.

larsf (Fri, 23 Jun 2017 10:57:00 GMT):
Can that be the reason to the problem?

davidkel (Fri, 23 Jun 2017 11:24:24 GMT):
@deepakvparmar if you are using the fabric-dev-server from composer-tools then you need to deploy with the pre-loaded userid of `PeerAdmin` (secret isn't important so put anything you like for the -s option)

Hello, question about receiving events that are emitted from a transaction processor function. I have a function defined to emit an event, and I am using the node-red flows to subscribe to events. When I execute my function, I actually receive the emitted event multiple times. Is that an expected behavior? If so, why? Thanks!

I'm trying to setup a composer development environment in ubuntu VM. But I keep getting the error Display ":0.0" not found whenever i Start code (VSCOde). I've tried setting the DISPLAY to localhost, my VM IP address, 127.0.0.1, but to no avail. Any suggestions on how to set it?

davidkel (Fri, 23 Jun 2017 14:22:23 GMT):
@dwakeman how many times do you receive the same event ? does it match any multiple of your environment ?

dwakeman (Fri, 23 Jun 2017 14:23:23 GMT):
Actually, I think it was my mistake. I had two different node-red flows trying to connect to two different fabric environments. When I got rid of one of the flows and restarted node-red it seemed to return back to normal.

mahoney1 (Fri, 23 Jun 2017 14:28:59 GMT):
@ShobhanaSundararaman hmm..in Ubuntu - I just installed it. I can launch from the Search (type VS.,..icon appears...launch) - or from command line in a terminal using 'code' where my DISPLAY var was set to :0 - I would try the first suggestion I made..did this as a non-root user.

@jeffgarratt that's an odd one. One thing I need to recheck but I thought that the queryInstantiatedChaincodes which is what is being called here required Peer Admin authority I know it gets called when we try to deploy as we check to see if the chaincode has already been instantiated and so don't attempt it again. There could have been other times it get's driven from playground but I've not seen it.

@MeenakshiSingh you can edit the config in the `fabric-dev-servers` if you like, but we provide no tooling or docs for helping you do that - that is and always be Fabric configuration - you need to use the Fabric docs and ask questions in the #fabric channel

@rohilsurana that is not possible at the moment. we might be able to do something as part of the new Composer query language to allow you to run a query like `SELECT org.acme.Asset WHERE (owner == _$currentParticipant)`

@rama_rahul run `composer -v`. if it does not say v0.8.x, then run `npm uninstall -g composer-cli && npm install -g composer-cli`

[ ](https://chat.hyperledger.org/channel/composer?msg=R5Z87FpvMTQiFZr5W) @mahoney1 Having no luck yet with the loopback-connector-composer. Following the guide, all works fine until I'm starting the server. In the docker logs of my ca, peer and 'chaincode' container I can see that my loopback application is connecting to them, and there are no errors there. But the last line I see when I start the loopback application is "Browse your REST API at http://0.0.0.0:3000/explorer". No comments about the loopback connector or having found model definitions. Also the ui at http://0.0.0.0:3000/explorer shows an empty swagger page without any endpoints.

im trying to connect a loopback server to an deployed composer network using the loopback-connector-composer

rikmoedt (Sat, 24 Jun 2017 16:05:03 GMT):
eventually the goal is to have one loopback server that can connect to multiple deployed networks

rikmoedt (Sat, 24 Jun 2017 16:06:12 GMT):
still figuring out what the right approach is. using the loopback connector, or code more ourselves using the composer-client npm package

sstone1 (Sat, 24 Jun 2017 16:07:05 GMT):
OK, well the lack of models suggests that you're not driving the LoopBack discovery process

sstone1 (Sat, 24 Jun 2017 16:07:38 GMT):
see the 2 composer-*.js boot scripts in here:

sstone1 (Sat, 24 Jun 2017 16:07:39 GMT):
https://github.com/hyperledger/composer/tree/master/packages/composer-rest-server/server/boot

sstone1 (Sat, 24 Jun 2017 16:07:49 GMT):
they drive the LoopBack discovery process and add all the models to LoopBack

sstone1 (Sat, 24 Jun 2017 16:08:02 GMT):
although the runtime one is only for the wallet + identity stuff

rikmoedt (Sat, 24 Jun 2017 16:12:31 GMT):
allright, il take a look at that. what approach would you suggest for the following process: on the loopback side we want to have one model called "trade". When the api is called to create a new trade, depending on the parties involved in that trade a different composer network need to be invoked. So the model is not directly one-on-one tied to a composer network but to a different one depending on the content of the trade. Is auto generating the models with the loopback discovery process still the right approach, or do we need to go in another direction

sstone1 (Sat, 24 Jun 2017 19:42:09 GMT):
@rikmoedt there are no labs that cover using the LoopBack connector in a LoopBack application; the only resources for this is the code is in the `composer-rest-server` (which is a normal LoopBack application) project linked to above.

SahilKapoor (Sun, 25 Jun 2017 19:11:05 GMT):
In Hyperledger Fabric Beta peers now enforce the concepts of admins and members. Admin user's identities and crypto material must be available to the peer at deployment. *To make that identity and its crypto material available, your must import it to your local keyValStore directory before deploying the business network.* To import the identity, use the composer identity import command. When importing an identity, you do not assign it a secret, however the composer network deploy command requires a secret. If you are using an imported identity, you can enter any value for the secret.

@wael The problem is usually down to one of the some dependent module for the connector hasn't been installed correctly. This can happen for a number of reasons. Version of node/npm being used. you did npm install using sudo or were the root user, you machine doesn't have enough memory (we recommend 4Gb min). You don't have python v2 installed or it isn't the default level of python when invoking the command python. These are the most common ones. Sometimes it can be resolved by clearing out your node_modules directory and redownloading using npm install.

I have deployed my .bna file onto a running Fabric v1 and brought it up on Composer REST server, however when I try to add an asset that has attributes that should be an empty array by default, it throws an error 422. ``` { "error": { "statusCode": 422, "name": "ValidationError", "message": "The `ibm_wsc_immunichain_Childform` instance is not valid.

mahoney1 (Mon, 26 Jun 2017 15:36:35 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=DG74xzw2iznyjQpkq) @jaguarg you can follow the example strategy at https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html to guide you and edit the COMPOSER_PROVIDERS env variable section to add your passport-local strategy. The NPM module is https://www.npmjs.com/package/passport-local and the steps to configure the strategy are shown there.

gkd720 (Mon, 26 Jun 2017 18:22:15 GMT):
I'm starting to go through the "Developer Tutorial for creating a HyperLedger Composer solution". I have all the prerequisites met. I started installing development tools from my home directory, and am doing the line: `npm install -g composer-cli`. I see some warnings about a few things being deprecated, and I'm assuming that's OK. But, I do get some access errors: `npm ERR! path ../lib/node_modules/composer-cli/cli.js npm ERR! code EACCES npm ERR! errno -13 npm ERR! syscall symlink npm ERR! Error: EACCES: permission denied, symlink '../lib/node_modules/composer-cli/cli.js' -> '/usr/local/bin/composer' npm ERR! at Error (native) npm ERR! { Error: EACCES: permission denied, symlink '../lib/node_modules/composer-cli/cli.js' -> '/usr/local/bin/composer' npm ERR! at Error (native) npm ERR! cause: npm ERR! { Error: EACCES: permission denied, symlink '../lib/node_modules/composer-cli/cli.js' -> '/usr/local/bin/composer' npm ERR! at Error (native) npm ERR! errno: -13, npm ERR! code: 'EACCES', npm ERR! syscall: 'symlink', npm ERR! path: '../lib/node_modules/composer-cli/cli.js', npm ERR! dest: '/usr/local/bin/composer' }, npm ERR! errno: -13, npm ERR! code: 'EACCES', npm ERR! syscall: 'symlink', npm ERR! path: '../lib/node_modules/composer-cli/cli.js', npm ERR! dest: '/usr/local/bin/composer' }` And it suggests rerunning as root. So I did. But now I get and unending stream of what looks like the same error: `gyp WARN EACCES user "root" does not have permission to access the dev dir "/Users/gkd/.node-gyp/6.10.3" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/local/lib/node_modules/composer-cli/node_modules/grpc/.node-gyp" gyp WARN EACCES user "root" does not have permission to access the dev dir "/usr/local/lib/node_modules/composer-cli/node_modules/grpc/.node-gyp/6.10.3" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/local/lib/node_modules/composer-cli/node_modules/grpc/.node-gyp"` So I'm not sure how to proceed. Any thoughts? Thanks.

@gks720 instead of running npm install of composer-cli as root, I recommend changing your npm prefix to a directory you have access to. The original problem is your non-root user probably cannot update /usr/local/bin. E.g. here is what I do to set the npm prefix to my home directory, ... *npm config set prefix /home/bcuser at which point global binaries are placed in /home/bcuser/bin (actually usually just links to /home/bcuser/lib/....) which is in my PATH, and the modules are placed in /home/bcuser/lib ... this way you can do all the global installs as non-root per the Composer team's recommendation

davidkel (Tue, 27 Jun 2017 06:42:38 GMT):
@rama_rahul You cannot use admin/adminpw to deploy a network as it won't have the authority to install chaincode onto the peer. If you are using he fabric-dev-server package then it will put an appropriate id into your KeyValStore called PeerAdmin which you should use. It doesn't have a secret but you need to specify something which can be anything. If you have created your own fabric then you need to look at composer identity import command to import a peer admin cert into your keyvalstore

@gauthampamu The sample applications repository can be found at https://github.com/hyperledger/composer-sample-applications and has been updated and all the samples will run on hyperledger fabric v1.0.

[ ](https://chat.hyperledger.org/channel/composer?msg=uNG6zwHLL7aukkeR2) @chtn2109 Composer deploys to Fabric - so you use standard Fabric tools and utilities to manage your peers. Please refer to the Fabric docs for details.

chtn2109 (Tue, 27 Jun 2017 07:39:57 GMT):

chtn2109 (Tue, 27 Jun 2017 07:46:33 GMT):
@dselman One more thing that Is Participants in composer is a form of peers in hyperledger fabric??

dselman (Tue, 27 Jun 2017 07:48:59 GMT):
No, Participants and peers are different concepts. A Peer is typically run by an entity (a company) that has such a large stake in the running of the business network that they want their own copy of the ledger and are prepared to pay (IT cost) for the infrastructure to run a peer node. A Participant on the other hand is just someone who _participates_ in the business network and has credentials to access the network. They could simply be an end-user (a farmer, a deliver driver) etc.

dselman (Tue, 27 Jun 2017 07:49:47 GMT):
That would be a good Q&A to put on StackOverflow - can you do that please?

uber.twin (Tue, 27 Jun 2017 08:34:04 GMT):
@dselman Suppose the access mode is by REST API. Then, typically, the running of the REST server will be the responsibility of the Participant, right?

uber.twin (Tue, 27 Jun 2017 08:34:04 GMT):
@dselman Suppose the access mode is by REST API. Then, typically, the running of the REST server will be the responsibility of the Participant, right? but that would seem a little bit excessive for an end-user application platform.

chtn2109 (Tue, 27 Jun 2017 08:44:37 GMT):
Thanks @dselman Sure, I'll put it on SO, but one more question coming on my head, if a company is a peer, who is responsible for run a peer node with it's own copy of ledger (database) so why company should use blockchain instead of simple client server (centrallly database) approach?

dselman (Tue, 27 Jun 2017 08:51:51 GMT):
That's a pretty general "why blockchain" question... there are a range of factors but a big one is trust. The IBM site does a good job of explaining it (other sources are available!): https://www.ibm.com/developerworks/cloud/library/cl-blockchain-basics-intro-bluemix-trs/

chtn2109 (Tue, 27 Jun 2017 08:59:40 GMT):
@dselman that's not I mean to say, After implementing composer tutorial, I felt that it is something like central database like implementation because only one peer node is there which interact with blockchain for store and retrieval of assets and participant and transactions, though composer-rest-client any application interact VIA API's, so where is the role of other peers, what are they? & where they reside on a business network & How could we create new Peers?

dselman (Tue, 27 Jun 2017 09:02:05 GMT):
That is not correct -- Composer stores all its data on the blockchain (via transactions and world-state) and it is subject to the same consensus mechanisms as any other chaincode running on Fabric. I.e. each peer processes all transactions and has its own copy of the ledger. If any of the peers try to "cheat" and update the ledger differently to the other peers they will be found out and their transactions will roll back. Simplified explanation - refer to the Fabric docs for all the options etc.

chtn2109 (Tue, 27 Jun 2017 09:09:11 GMT):
@dselman for example a logistic company implements the blockchain, so there different departments like customer care, accounts, shipping & others, each department have a peer node so that every peer has an updated information and each can interact with theblockchain as well? is that a correct philosophy for peers?

@dselman Is there a way to implement chaincode via hyperledger-composer?

sstone1 (Tue, 27 Jun 2017 09:41:54 GMT):
@chtn2109 the business network definition you build in Composer is the chaincode (or smart contract if you prefer). the business network definition gets deployed to the Blockchain (Fabric) and becomes a running chaincode, at which point you start interacting with it. you can implement your business logic using JavaScript by writing transaction processor functions; these get executed on the Blockchain by the peer nodes when you submit transactions.

@sstone1 I need to integrate a couple of dozens of banks. It is very likely each of them will want their own peer and than a corresponding composer-rest-server for access; On top of it, a web application for each of them, talking to their respective composer-rest-server instance, providing end-user functonality. Would you think this scenario is feasible?

if you have multiple organisations locally, each one will have their own peer

sstone1 (Tue, 27 Jun 2017 10:38:50 GMT):
you can define a Composer connection profile for each organisation (with the URLs of that organisations peers)

sstone1 (Tue, 27 Jun 2017 10:38:59 GMT):
then you start a REST server for each Composer connection profile

why does each bank need it's own peer in that situation? because they don't trust the other banks, and they want to endorse transactions and take part in consensus?

[ ](https://chat.hyperledger.org/channel/composer?msg=kQ8fm5T4hQLQSuwbM) @jaguarg thanks for posting your version info. Could you also provide your python version please (python --version). The problem you describe usually means either that the node package didn't build properly when you did an npm install -g composer-cli.or potentially not enough memory (seen this on Stack Overflow). - how much memory do you have ?

sstone1 (Tue, 27 Jun 2017 10:55:01 GMT):
the REST server is easy for clients to use, but it comes with a price - it must be trusted by the client - it needs the private key(s) of the clients to sign and submit transactions to the Blockchain. that is why I believe in 99% of configurations, each "non trusting participant" will want their own instance of the REST server.

since a rest server stands for a participant, would it make sense for multiple banks to use the same connection profile?

uber.twin (Tue, 27 Jun 2017 10:57:08 GMT):
right, they'll need a dedicated rest server

chtn2109 (Tue, 27 Jun 2017 10:59:42 GMT):
@sstone1 how can we achive that each peer node connected through a single blockchain locally?

uber.twin (Tue, 27 Jun 2017 11:01:05 GMT):
@sstone1 so then, there would be local rest servers, on the bank's premises, and a shared location used for running the peers in close proximity?

sstone1 (Tue, 27 Jun 2017 11:02:23 GMT):
@chtn2109 that is a Fabric configuration question, you need to ask in #fabric or read the Fabric docs; Composer is not a Blockchain platform, Composer does not have peer nodes - it deploys down to a Blockchain platform such as Fabric and runs on Fabrics peer nodes.

sstone1 (Tue, 27 Jun 2017 11:02:45 GMT):
We include a sample, very basic Fabric configuration for an easy getting started experience

sstone1 (Tue, 27 Jun 2017 11:03:32 GMT):
That sort of sounds right - I'm not sure why the peers and REST server have to be in different places though

sstone1 (Tue, 27 Jun 2017 11:03:39 GMT):
(that's for @uber.twin)

sstone1 (Tue, 27 Jun 2017 11:03:58 GMT):
the bank could run both their peer nodes and their REST servers in the cloud somewhere, and so could all the other banks

uber.twin (Tue, 27 Jun 2017 11:10:56 GMT):
@sstone1 apart of the topology conosiderations, would a network of 30-50 peers be performing acceptaby in terms of performance?

@jmcnevin do it on the client side and include the id in the incoming transaction. Anything based on a counter will not scale, anything based on UUID or random generation will fail consensus across peers.

Wow. I made it to the end of "Developer Tutorial for creating a Hyperledger Composer solution". Everything worked as expected. I'll probably try my own "business model" next. But, in the Angular app created from `yo hyperledger-composer`, I see it can't make a new Participant (yet). Looking into "yeoman", I don't suspect the effort is trivial, but are there still plans to provide this? And submit transactions? Thanks.

I'd check with the team, but thought there was a default endorsement policy for a channel and in fabric there was the capability to define an endorsement policy for a chaincode. However using composer I think it will just use the default endorsement policy for the channel

Hi, I created a sample model and generated the .bna file. I deployed the bna file into my fabric using the command "composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString". Then created REST api using the command "composer-rest-server -p hlfv1 -n my-network -i admin -s adminpw -N never". I was able to view the assets and participants in the API Explorer. Then I made changes to my mode file (.cto) and re-generated the .bna file. It was successful as I was able to import the new file into the playground and view my changes. But when I deploy the new file into the fabric and give the REST API (composer-rest-server -p hlfv1 -n my-network -i admin -s adminpw -N never), the changes are not getting refelected in the REST API explorer. Is there something that I'm missing in deploying to the fabric network and generating new API?

mbwhite (Wed, 28 Jun 2017 11:14:01 GMT):
@ShobhanaSundararaman was the fabric still running when you deployed the new bna file? If so then rather than do a `composer deploy` do a `composer update`

@ShobhanaSundararaman The fabric is a simple development environment provided. If you want to create your own fabric then you need to go to http://hyperledger-fabric.readthedocs.io/en/latest/ to find out how to do this. Technically I believe it is possible to modify a channel to do things like add new organisations as well. Again to create new channels you need to refer to the hyperledger fabric documentation.

@gen_el so it really is some sort of network problem trying to communicate with the fabric. `docker ps` will show the docker containers running as well as the ports they are listening on. It might be worth specifying your the explicit IP address rather than localhost in you connection profile.

Can i use a connection profile without "ca"? @davidkel

davidkel (Wed, 28 Jun 2017 13:19:59 GMT):

so which process will handle events? Can any peer node play that role?

davidkel (Wed, 28 Jun 2017 13:29:05 GMT):
@gen_el I wouldn't use 0.0.0.0 as the ip address. I would use the explicit IP address of your machine. Each peer node has 2 end points that we need to connect to. A Request endpoint and an Event End point. We do this for all peers listed in the connection profile

@dselman @sstone1 @caroline-church .. looking at EPIC 55 (https://github.com/hyperledger/composer/issues/55) for the Historian ...a request came up on our project to show the delta of what changed on an asset...so if participant A update fields B and C on Monday and then participant B updated fields B and C on Wed.to new values, either participants could see the history of change to fields B and C...will that be possible via the APIs of the Historian?

Is it possible to install specific versions composer cli tools and playground locally? For example, if I create a script now for Composer .8, can I specity that someone in the commands?

gen_el (Wed, 28 Jun 2017 13:50:04 GMT):
I checked, those ports are open. @davidkel

gen_el (Wed, 28 Jun 2017 13:50:06 GMT):

davidkel (Wed, 28 Jun 2017 13:56:20 GMT):
@JennFoley Yes you can, for example to install composer-cli 0.7.5 you can use the command `npm install -g composer@0.7.5`

and got that error , any suggestions ?

mbwhite (Wed, 28 Jun 2017 14:07:49 GMT):
The new Fabric beta requires the deploy to have `-i PeerAdmin -s anything`

mbwhite (Wed, 28 Jun 2017 14:07:53 GMT):
try that

@mbwhite

davidkel (Wed, 28 Jun 2017 14:12:15 GMT):
@wael it cannot talk to your fabric. if you think you have the connection profile correctly set up correctly try changing the addresses in you connection profile from `localhost` to your machine's explicit ip address

davidkel (Wed, 28 Jun 2017 14:12:15 GMT):

wael (Wed, 28 Jun 2017 14:17:18 GMT):
@davidkel where should I check the connection profile ?

davidkel (Wed, 28 Jun 2017 14:24:26 GMT):
@wael details about connection profiles are here https://hyperledger.github.io/composer/reference/connectionprofile.html

wael (Wed, 28 Jun 2017 14:25:38 GMT):
@davidkel so I have done everything right , and changed local host to my machine's explicit ip , and also the same error got

gen_el (Wed, 28 Jun 2017 14:28:28 GMT):
Issue still persist @davidkel

gen_el (Wed, 28 Jun 2017 14:29:28 GMT):
I have changed TLS_ENABLED=false for CA, PEER and ORDERER

gen_el (Wed, 28 Jun 2017 14:29:42 GMT):
I used my actual system IP

gen_el (Wed, 28 Jun 2017 14:30:23 GMT):
I got a different error, more like @wael

gen_el (Wed, 28 Jun 2017 14:30:32 GMT):
Bottom line issues persist

davidkel (Wed, 28 Jun 2017 14:30:46 GMT):
@wael `export GRPC_TRACE=all` can provide some basic debug info about connection failures

gen_el (Wed, 28 Jun 2017 14:31:17 GMT):
i need to know how to create a connection profile including the keyValStore

davidkel (Wed, 28 Jun 2017 14:31:33 GMT):
@gen_el https://hyperledger.github.io/composer/reference/connectionprofile.html

gen_el (Wed, 28 Jun 2017 14:34:04 GMT):
I have gone through it

davidkel (Wed, 28 Jun 2017 14:38:59 GMT):
@gen_el We do have a standalone development fabric you can use as described in https://hyperledger.github.io/composer/installing/development-tools.html which might be a better place to get started. I don't know why you cannot connect to your fabric if you believe you have defined the connection profile correctly

gen_el (Wed, 28 Jun 2017 14:39:35 GMT):
At what point is the .hfc-key-store generated @davidkel

davidkel (Wed, 28 Jun 2017 14:42:30 GMT):
@gen_el this is the location where your certificates required to communicate with fabric are stored. As you will need to import your peer admin certs into the directory specified by keyValStore. However your connection failures meant you aren't even getting that far. To import your Peer Admin certs see the command https://hyperledger.github.io/composer/reference/composer.identity.import.html

gen_el (Wed, 28 Jun 2017 14:47:32 GMT):
Ok. Thanks @davidkel I will review the development network used in the composer tutorial and compare.

gen_el (Wed, 28 Jun 2017 16:42:17 GMT):
@davidkel Solved! As i suspected, the problem was the peer admin identity. Once i imported them into the keyvalstore, composer was able to deploy the .bna file.

gkd720 (Wed, 28 Jun 2017 18:07:26 GMT):
If I didn't want to create an app using "yo", but just try to manually write some javascript code, is this sane? What might I model it after? I looked at files in/below ~/composer/my-network/my-app, but I couldn't find any "*.js" files that looked related. How is the angular app code invoked, and where is the "main" program? Or does it have to be a node.js program? Any pointers on how to write an app manually? Is this even sane? Thanks.[ ](https://chat.hyperledger.org/channel/composer?msg=JbKbQTGtgnZ29izLF) @dselman

sstone1 (Wed, 28 Jun 2017 18:25:36 GMT):
@gkd720 you can write any application you want, using either the Composer client APIs from a Node.js program or the REST APIs provided by the Composer REST server

sstone1 (Wed, 28 Jun 2017 18:25:59 GMT):
The generated application that Yo builds is simply an Angular app that interacts with the REST APIs provided by the Composer REST server

davidkel (Wed, 28 Jun 2017 21:20:45 GMT):
@JohnWhitton Can you check that the level of fabric you are trying to interact with is still alpha1 ? I am assuming that this is a local fabric you are running.

JohnWhitton (Wed, 28 Jun 2017 21:21:12 GMT):
Hey @davidkel we are deploying this on GCP

davidkel (Wed, 28 Jun 2017 21:22:09 GMT):
@JohnWhitton Sorry I don't know what GCP is

JohnWhitton (Wed, 28 Jun 2017 21:22:57 GMT):
@davidkel Google Cloud Platform Here is what we use to download fabric ``` # Pull and tag the latest Hyperledger Fabric base image. docker pull hyperledger/fabric-peer:x86_64-1.0.0-alpha docker pull hyperledger/fabric-ca:x86_64-1.0.0-alpha docker pull hyperledger/fabric-ccenv:x86_64-1.0.0-alpha docker pull hyperledger/fabric-orderer:x86_64-1.0.0-alpha docker pull hyperledger/fabric-couchdb:x86_64-1.0.0-alpha ```

JohnWhitton (Wed, 28 Jun 2017 21:25:26 GMT):
Basically where I'm at is I have this downloaded and running locally and I've deployed all the containers to GCP But when I go to create a channel I'm running into an issue So my thought is that it's a configuration error on my end (e.g. I made a mistake in my connection.json or config.json)

davidkel (Wed, 28 Jun 2017 21:26:32 GMT):
@JohnWhitton I would check the logs of the orderer to see if there is any info indicating what went wrog

davidkel (Wed, 28 Jun 2017 21:32:19 GMT):
@JohnWhitton yeah likely there genesis block isn't accurate ot the transaction to create the channel isn't quite right. Unfortunately you probably need to ask on the other fabric channels for specifics of orderer problems. But fabric has moved on quite a bit since the alpha so they may suggest trying newer versions

@JohnWhitton looks like it was taken from either our systest suite. No New version as we moved away from using the node sdk for creating and joining channels. Our latest code base has moved on further now to beta1 which now handles new fabric security implementations

@JohnWhitton Our fabric runtime is a simple runtime meant for development purposes only. I would suggest reading the hyperledger fabric document website to get more information about setting up a bespoke fabric environment.

can anyone point me at an example of the `composer identity issue` command? I'm trying to setup a participant for an identity I've imported using `composer identity import`

I think I probably also need to understand `composer participant add` in order to do this..?

@mahoney1 hm, I can't get it working. I'm trying to create an admin participant so that my app can get an admin-level connection. I've successfully imported the `Admin@org1.example.com` identity using `composer identity import` with `-u PeerAdmin`. Now that I have that, I want to give this identity a participant. I've done `composer participant add` successfully, and now have a participant `net.test.AdminMember#PeerAdmin` to match. When I try the final step, `composer identity issue -p test_hl1 -n net-test -i PeerAdmin -s Xurw3yU9zI0l -u PeerAdmin -a net.test.AdminMember#PeerAdmin --issuer`, the CA is rejecting it: ``` ca.dev.everledger.io | {"id":"PeerAdmin","type":"client","affiliation":"org1","max_enrollments":0,"attrs":[{"name":"hf.Registrar.Roles","value":"client"}],"caName":"ca.dev.everledger.io"} ca.dev.everledger.io | 2017/06/29 07:02:02 [DEBUG] Directing traffic to CA ca.dev.everledger.io ca.dev.everledger.io | 2017/06/29 07:02:02 [DEBUG] Checking for revocation/expiration of certificate owned by 'Admin@org1.example.com' ca.dev.everledger.io | 2017/06/29 07:02:02 [DEBUG] DB: Get certificate by serial (d64e88683fa3fe169accb8428595edf6) and aki (27bc2ddffdebf9c4618a3c2cdffba1c72691514a9613ca02fe1ce8172b9651e1) ca.dev.everledger.io | 2017/06/29 07:02:02 [ERROR] No certificates found for provided serial and aki ``` any ideas?

pospi (Thu, 29 Jun 2017 07:03:12 GMT):
is there some restriction that you can't assign the identity used to make the request to a participant, perhaps?

JohnWhitton (Thu, 29 Jun 2017 07:05:56 GMT):
Been a long day, I'll leave this message here and grab some sleep and see if some pearls of wisdom are available on the morrow. If you see my comments above, I've spent the last couple of days trying to deploy a fabric rest server on Google Cloud Platform. This involves creating a CA, Orderer, a couple of peers and then deploying a business network on top Here are the latest logs, any advice as to what I'm missing in my config is appreciated (it runs fine locally)

Also if it's a versioning issue let me know (currently using composer 0.7.0)

pospi (Thu, 29 Jun 2017 07:07:56 GMT):
@JohnWhitton it probably is, Composer 0.8 had lots of compatibility fixes for fabric 1.0.0-beta in it

davidkel (Thu, 29 Jun 2017 07:14:00 GMT):
@pospi you can't issue an identity for an imported identity (as part of the issue identity command is to interact with the ca server to create a new enrollment id and secret) and I don't think you want to do so for PeerAdmin either. That id is really a fabric level id not a business network id and is required only for the deploy stage. Once deployed you should work with other ids.

davidkel (Thu, 29 Jun 2017 07:22:14 GMT):
@pvrbharg The failure is because the directory specified in your hlfv1 profile under keyValStore cannot be created or accessed. Most likely you have specified a directory such as /home/fred/.hfc-key-store but the user fred doesn't exist so the directory /home/fred doesn't exist. One solution would be just to create the directory path yourself.

pospi (Thu, 29 Jun 2017 07:44:39 GMT):
OK thanks @davidkel I'll try making a new separate identity then

pospi (Thu, 29 Jun 2017 07:50:36 GMT):
hmm, same error @davidkel @mahoney1 - the command I'm trying now is the same as before except that I'm using a different newUserId & participantId: `composer identity issue -p test_hl1 -n net-test -i PeerAdmin -s Xurw3yU9zI0l -u ClientAdmin -a net.test.AdminMember#ClientAdmin --issuer`. I would have assumed that the imported admin identity would still be the one used to run the command, or is this not the case?

davidkel (Thu, 29 Jun 2017 07:59:12 GMT):
@pospi the id you need to use is `-i admin -s adminpw` this is the userid is understood by the ca server and also has the authority to issue new identities. In HLF V1 the CA is now a completely separate entity to the system that runs the fabric

davidkel (Thu, 29 Jun 2017 07:59:12 GMT):

that gives me `Error: error trying login and get user Context. Error: error trying to enroll user. Error: Error: Invalid results returned ::FORBIDDEN`... does it depend on the generated crypto assets?

davidkel (Thu, 29 Jun 2017 08:01:06 GMT):
@pospi how did you start the ca server in your environment ?

pospi (Thu, 29 Jun 2017 08:01:14 GMT):

pospi (Thu, 29 Jun 2017 08:02:03 GMT):
but maybe I need to go back and regenerate my crypto assets, as I generated them with an early version when the beta first came out and I'm unsure whether those binaries were actually up to date at the time...

pospi (Thu, 29 Jun 2017 08:02:54 GMT):

Does Composer allow logic for query/invoke across different chaincodes? Example a peer which is on two channels with two chaincodes in each channel

davidkel (Thu, 29 Jun 2017 08:05:42 GMT):
@pospi the ca server is started for example ` command: sh -c 'fabric-ca-server start --ca.certfile /etc/hyperledger/fabric-ca-server-config/org1.example.com-cert.pem --ca.keyfile /etc/hyperledger/fabric-ca-server-config/a22daf356b2aab5792ea53e35f66fccef1d7f1aa2b3a2b92dbfbf96a448ea26a_sk -b admin:adminpw -d' ` the certfile and the keyfile should represent the organisation that the peer is part of so in the above example the material comes from the org1.example.com organisation

davidkel (Thu, 29 Jun 2017 08:05:42 GMT):
@pospi the ca server is started for example ``` command: sh -c 'fabric-ca-server start --ca.certfile /etc/hyperledger/fabric-ca-server-config/org1.example.com-cert.pem --ca.keyfile /etc/hyperledger/fabric-ca-server-config/a22daf356b2aab5792ea53e35f66fccef1d7f1aa2b3a2b92dbfbf96a448ea26a_sk -b admin:adminpw -d' ``` the certfile and the keyfile should represent the organisation that the peer is part of so in the above example the material comes from the org1.example.com organisation

That should mean it will issue ids which are seen as part of the same organisation

pospi (Thu, 29 Jun 2017 08:06:47 GMT):
ahhhhh OK I think I have it then. I only have a CA for the orderer running, need another one for the peer org?

davidkel (Thu, 29 Jun 2017 08:07:37 GMT):
@pospi if you want to issue identities for that organisation then you need the ca for that organisation

davidkel (Thu, 29 Jun 2017 08:08:32 GMT):
@JonathanTan not sure I understand the question, could you provide an example of what you are trying to do within the context of a business network ?

JonathanTan (Thu, 29 Jun 2017 08:09:55 GMT):
@davidkel for example, bank A has channel 1 and channel 2, channel 1 has chaincode 1 and channel 2 has chaincode 2

JonathanTan (Thu, 29 Jun 2017 08:10:49 GMT):
as Bank A , we want from chaincode 1 to query/invoke chaincode 2 functions

JonathanTan (Thu, 29 Jun 2017 08:11:23 GMT):
use case is that chaincode 1 is in channel 1 between Bank A and Bank B

JonathanTan (Thu, 29 Jun 2017 08:11:37 GMT):
chaincode 2 is in channel 2 between Bank A and Bank C

JonathanTan (Thu, 29 Jun 2017 08:12:02 GMT):
Bank A has a account balance in chaincode 1's state/chain

JonathanTan (Thu, 29 Jun 2017 08:12:23 GMT):
and now wants to transfer $$ to it's account in chaincode 2's statechain

JonathanTan (Thu, 29 Jun 2017 08:13:32 GMT):
chaincode 1 and 2 could be the same Logic/contract deployed in different channels

davidkel (Thu, 29 Jun 2017 08:18:06 GMT):
@JonathanTan No composer doesn't currently have any direct way to communicate with other business networks as yet. Business networks can emit events to external systems so you could create an intermediary client application to do something for you. If you feel this is a requirement feel free to submit an issue for consideration.

dselman (Thu, 29 Jun 2017 08:18:53 GMT):
@JonathanTan we call this feature "links" for Composer -- it is in the backlog but not yet implemented.

@dselman hi, after doing a network undeploy, the deploy operation doesn't seem to work. I need to tear down the containers and restart them to be able to do a successful deploy again so, is the network deploy-undeploy suppose to work with the composer 0.8 and fabric v1 beta images?

sstone1 (Thu, 29 Jun 2017 08:25:23 GMT):
@uber.twin Fabric does not support chaincode undeploy/stop, so we cannot do anything about that

sstone1 (Thu, 29 Jun 2017 08:25:42 GMT):
If you want chaincode undeploy/stop in Composer, you need to get the Fabric team to add it first :)

uber.twin (Thu, 29 Jun 2017 08:27:42 GMT):
@sstone1 is this a fabric V1 issue? because it used to work the fabric 0.6

sstone1 (Thu, 29 Jun 2017 08:28:18 GMT):
Fabric v0.6 had "random" hashed chaincode IDs

sstone1 (Thu, 29 Jun 2017 08:28:38 GMT):
When we did an undeploy at v0.6, we simply forgot about the chaincode ID for a business network, and then deployed a new one (which had a new chaincode ID)

sstone1 (Thu, 29 Jun 2017 08:28:45 GMT):
The v0.6 chaincode was still running though

sstone1 (Thu, 29 Jun 2017 08:28:56 GMT):
In Fabric v1.0, we can use the business network name as the chaincode ID

sstone1 (Thu, 29 Jun 2017 08:29:08 GMT):
however there is no way to get rid of the chaincode

pospi (Thu, 29 Jun 2017 08:29:26 GMT):
_sigh_ @davidkel nup, it's all broken. I have changed my connection profile to point to the peer's CA instead of the order org's one. I use the imported `PeerAdmin` to create the participant, because the `admin/adminpw` credentials don't seem to work for that. I'm then trying to use `admin/adminpw` for the `identity issue` command but it gives the same `event message must be properly signed by an identity from the same organization as the peer` error as before. I think I'm going to have to comb over my configuration for the nth time, I have no idea if the peer is incorrectly bound to the orderer CA or something, but this seems likely

pospi (Thu, 29 Jun 2017 08:31:21 GMT):
there are so many moving parts here you're basically insane if you try to do anything other than run a totally unmodified stock dev configuration. wish I had done this the easy way and not bothered to try to understand how things work

uber.twin (Thu, 29 Jun 2017 08:36:01 GMT):
@sstone1 alright, thank you for clarifying it. for the future though, do you think it'll be possible to update the chaincode and keep the asset, participant and transaction repositories?

dselman (Thu, 29 Jun 2017 08:37:12 GMT):
yes

sstone1 (Thu, 29 Jun 2017 08:44:14 GMT):
@uber.twin yes - the current thinking is to introduce an "upgrade" command which will upgrade the level of Composer. Note that today you can use "update" to update the business network definition without losing your assets, participants, and transactions.

Hey, has anyone tried to connect local playground to HSBN on bluemix (fabric v1)? It looks like that not working now. I am receiving "404 not found" from CA on "enroll user" operation

davidkel (Thu, 29 Jun 2017 09:16:17 GMT):
@pospi I will have to use the PeerAdmin for deploy actions. For all business network interactions you should use ids made available from the ca. admin is a ca userid and if you start the ca in the manner I posted then that is the only userid you have to start with from the ca . Also it won't have any peer or channel authority (unless you constuct a fabric that explicitly works that way which won't be trivial). A CA is not bound to a peer or orderer, it is a Certificate Authority and you provide crypto material from a specific organisation so that it can issue crypto material that represents that organisation and associated MSPId.

pospi (Thu, 29 Jun 2017 09:17:19 GMT):
hmm, OK... but I have tried using the credentials given in the CA startup command to create a new participant and those don't work- so it seems that creating a participant and issuing an identity to it must be done by different users?

germanhs (Thu, 29 Jun 2017 10:55:57 GMT):
Can you store the cookies from the passport strategies on the other server (related to my previous question).. Because it seems the passport node module sets the cookie but on the rest server thats the problem so i cant access from my application server

mahoney1 (Thu, 29 Jun 2017 11:02:15 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=9GxJYZZegcipiJMNg) @wael hi there, what version of python ('python --version') do you have installed and what version of docker please?

wael (Thu, 29 Jun 2017 11:03:00 GMT):
@mahoney1 Python 2.7.13

wael (Thu, 29 Jun 2017 11:03:20 GMT):
Docker version 17.03.1-ce, build c6d412e

sstone1 (Thu, 29 Jun 2017 11:11:04 GMT):
@germanhs cookies are per server; the auth token *needs* to be associated with the rest server. if this is in a web browser, then when your application on otherserver calls the rest server, the cookies associated with the rest server will be ued.

mahoney1 (Thu, 29 Jun 2017 11:18:16 GMT):
thanks @wael - your versions posted seem fine. I am assuming your Fabric is running local given your localhost connection profile resolution? The problem is usually down to one of the dependent modules for the connector hasn't been installed correctly. This can happen for a number of reasons. Can you confirm you didn't do an npm install -g composer-cli as root or as sudo user ? Also, if you've not already confirmed, how many Gbs memory in your environment?

sachaLiguori (Thu, 29 Jun 2017 11:21:24 GMT):
@davidkel yes I've followed this tutorial but what is the default peerAdmin's Enrollment secret ?

wael (Thu, 29 Jun 2017 11:22:57 GMT):
@mahoney1 what do you mean by install composer-cli as root ? sudo I didn't use

davidkel (Thu, 29 Jun 2017 11:24:59 GMT):
@sachaLiguori it doesn't have a secret as it is already enrolled. However you still have to provide something for the secret so just put in anything you like

wael (Thu, 29 Jun 2017 11:28:31 GMT):
@mahoney1 I have 16GB memory

mahoney1 (Thu, 29 Jun 2017 11:46:48 GMT):
thanks @wael - so have you previously created a hlfv1 profile for this Fabric environment or deployed a business network or tested (eg. using composer network ping -n my-network -p hlfv1 -i admin -s adminpw) . Just curious if you have currently/previously been able to connect to Fabric from the CLI in your dev environment.

wael (Thu, 29 Jun 2017 11:48:24 GMT):
@mahoney1 yes I have been able to connect Fabric from the CLI

wael (Thu, 29 Jun 2017 11:49:07 GMT):
@mahoney1 what do you mean by install composer-cli as root ? sudo I didn't use

wael (Thu, 29 Jun 2017 11:49:28 GMT):
I tried to run my business network also with type embedded it works

mahoney1 (Thu, 29 Jun 2017 11:49:52 GMT):
ok and can you connect currently to your localhost environment as a matter of interest ? 'root' was a question as to whether you might have been using 'root' user on Linux, but clearly you're not using this, so you can ignore

wael (Thu, 29 Jun 2017 11:51:01 GMT):
excuse me I didn't understand what you asked

@sstone1 hi, when performing a rest GET operation for transactions, is there a way to filter by transaction class?

sstone1 (Thu, 29 Jun 2017 12:31:47 GMT):
@uber.twin no, not at the moment

sstone1 (Thu, 29 Jun 2017 12:32:27 GMT):
the new query functionality coming in todays release should allow you to do it from the node.js APIs

sstone1 (Thu, 29 Jun 2017 12:32:33 GMT):
but its not exposed in the REST APIs yet

uber.twin (Thu, 29 Jun 2017 12:34:33 GMT):
it seems strange because they appear to be stored in dedicated registries, isn't it?

sstone1 (Thu, 29 Jun 2017 12:34:56 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=CdS7A5H4HJXLeHiCR) @wael this is the same issue as before concerning dependent modules for composer-connector-hlfv1 - embedded connection does not test the Fabric. Are you running with Fabric v1.0 beta and did you use this setup https://hyperledger.github.io/composer/installing/development-tools.html to get your Dev environment up and running. If not, would recommend ensuring you pull this Fabric / composer level. Otherwise would suggest doing npm uninstall -g composer-cli then npm install -g composer-cli 2>&1 | tee -a build.log to capture everything to a logfile - and see if the dependent modules are installed.

wael (Thu, 29 Jun 2017 13:42:41 GMT):

Hi, while using factory.newResource() how can I generate the resource identifier automatically?

dselman (Thu, 29 Jun 2017 20:32:41 GMT):
You can't -- it should be generated on the client and passed in on the transaction. Any other mechanism either doesn't scale, or will have consensus issues (or both).

sstone1 (Thu, 29 Jun 2017 20:33:22 GMT):

davidkel (Thu, 29 Jun 2017 21:51:57 GMT):
@theophoric It's a problem with fabric not reporting the fact that the transaction is signed by a user who isn't authorised to install chaincode on the peer. If you are using our development fabric environment from composer-tools then it will preenroll a certificate from the peer that is authorised to install chaincode onto it. It get's registered as `PeerAdmin`. As it's preenrolled there is no secret but unfortunately you still have to supply one ` composer network deploy -a -p hlfv1 -i PeerAdmin -s anything`

Ok I am back and read your answer @sstone1 but somehow it doesnt work thats why I try to duplicate the token from restserver to appserver and then hand it over in the header of every request (tested in Postman that works)

germanhs (Fri, 30 Jun 2017 02:19:22 GMT):
The problem: restserver/auth/passport --> I login and authentificate --> restserver/auth/callback sets the cookie and creates a wallet and stuff --> successRedirect to my appserver (HTML5 Application). But now in this application when I send a request ($.ajax POST / GET) I always get the authorization error while on the restserver I can send requests with the swagger UI without getting an error. Please help me :(

germanhs (Fri, 30 Jun 2017 02:20:48 GMT):
So what I did was debugging this process found the cookie set on the callback page then copied it into postman as header of my request and then it works. Do I really need to duplicate it and if yes how? If no, what am I doing wrong then?

germanhs (Fri, 30 Jun 2017 02:25:38 GMT):
The server etc is public so if somebody has time to check it I would hand over the URL in a PM. Thanks in advance

Okay for other people having the same problem. For crossorigin access you need to specify in your ajax request that you want to use the credentials cookie from the other (rest) server: Just add this to the AJAX Request: xhrFields: { withCredentials: true }

Guys and girls.... It's really hard to follow your questions here. They are multipart, you supply additional information and they are interleaved. Differences in timezone also mean that some questions quickly get lost. I would *really* encourage you to ask questions on StackOverflow. You can format code, attach documents, up vote answers, offer a bounty for answers, search for existing answers etc.

@SethiSaab So is this one time move of data or would you want to have this as an going process? i.e. shadow active directory.

mbwhite (Fri, 30 Jun 2017 14:51:40 GMT):
Either way - really what you will need to do are (1) Model in composer the structure of the employees data (2) Write an application to move the data - or use something like Node-REDs integration capabilities - to keep the data in sync.

mbwhite (Fri, 30 Jun 2017 14:52:07 GMT):
Or indeed look into the Loopback Framework - that might be a good starting point if Loopback has an Active Directory connector

mbwhite (Fri, 30 Jun 2017 14:58:13 GMT):
I would recommend going to the Composer webpage and learning about how that works - there are some good tutorials on there. That will give you a feeling for what it can do. Keep in mind that Hyperledger Fabric is the core blockchain technology on which Hyperledger Composer sits to make your life as a developer a lot easier.

Hi all, I am able to view my business network on Composer REST server and add assets, participants, and transactions. However, I'm unable to get the filter to work properly. Whenever I make GET calls with a filter, it returns all the assets to me rather than just the one that matches the identifier. Is there a fix for this? I'm attaching a screenshot. Thanks!

@kvnlee the filter is not implemented yet - you can only filter by ID. we will be looking to map LoopBacks filter expressions to the new Composer query language in v0.9.0 to support this at a future date :)

kvnlee (Fri, 30 Jun 2017 15:06:02 GMT):
Thanks @sstone1 , so I am making a web app right now in Django, does that mean if a user wanted to get a specific asset a I would have to filter the response on the web app end?

sstone1 (Fri, 30 Jun 2017 15:06:55 GMT):
@kvnlee if you want to get a specific asset you can use the `/api/ibm.wsc.immunichain.Childform/{id}` API

kvnlee (Fri, 30 Jun 2017 15:08:14 GMT):
Right, but if I wanted to get a specific asset based on a different id (a foreign key, I suppose), I would have to filter it on the web app end

kvnlee (Fri, 30 Jun 2017 15:09:01 GMT):
It doesn't seem to fare well scalability-wise, so I'm looking forward to the update!

uber.twin (Fri, 30 Jun 2017 15:12:09 GMT):
@sstone1 hi, could you confirm that the businessNetworkConnection.connect() doesn't care about the password value i.e. any pasword is valid?

davidkel (Fri, 30 Jun 2017 15:19:32 GMT):
@uber.twin it's not a password, it's an enrollment secret. It will be used if the enrollment id provided has not yet been enrolled. Once enrolled your wallet will have the certificate representing that id and thus the secret is not required.

davidkel (Fri, 30 Jun 2017 15:28:41 GMT):
@uber.twin enrollment is the action of connecting to the ca server to download the crypto material (certificate) for the enrollment id into your wallet. A CA Server can for example decide that enrollment is a 1 time action. Once you have enrolled and obtained the certificate you cannot do so again.

I am a bit confused with all of the new identity stuff in composer 0.8.x and Fabric beta/rc1..... I see conflicting info in the new docs, and am hoping somebody can straighten me out. I have a new environment that is not the fabric-dev-server, and I am getting "not authorized" messages with composer. Do I need to issue a new identity to use with composer-cli, or import one? I tried importing one from the fabric-tools directory, as described in the docs, but I am getting an `x509 untrusted cert` type message. I'm guessing that's because somebody grabbed those identities from the peer CA for the fabric dev server. In my case, do I need to issue a new identity? If I do, do I need to also import it using composer cli to get the wallet in my keyvalstore?

arner (Fri, 30 Jun 2017 18:53:30 GMT):
To do the access control I need to get a model from another registry, so putting the logic in a transaction seemed like the right thing to do

dselman (Fri, 30 Jun 2017 18:53:34 GMT):
Including Dutch! ;-)

arner (Fri, 30 Jun 2017 18:53:44 GMT):

dselman (Fri, 30 Jun 2017 18:54:28 GMT):
Do you mean "get an asset from another registry"?

dselman (Fri, 30 Jun 2017 18:54:51 GMT):
Are you implementing procedural access control using `getCurrentParticipant()`?

arner (Fri, 30 Jun 2017 18:56:16 GMT):
To get the PersonalDetails an Access asset related to the PersonalDetails has to exist with granted = true as a field.

dselman (Fri, 30 Jun 2017 19:02:01 GMT):
I would put the logic in a helper function that you can call from your TP function.

Ok, but how can I make sure that this is called when I do a query for the PersonalDetails?

dselman (Fri, 30 Jun 2017 19:07:50 GMT):
Ok... back up a bit. Describe at the business level what you are trying to implement.

arner (Fri, 30 Jun 2017 19:09:39 GMT):
A civilian has personal details. A third party can request access to those details. In another transaction, the civilian can grant access to a certain field or type of info from his or her personal details (a nice example would be, 'is this person over 18').

dselman (Fri, 30 Jun 2017 19:11:45 GMT):
grant access to a specific participant, or in general?

arner (Fri, 30 Jun 2017 19:13:00 GMT):
The civilian (=participant) would grant access to the third party (=participant) to his personal details (=asset), preferably even to a certain field of this asset

dselman (Fri, 30 Jun 2017 19:14:10 GMT):

dwakeman (Fri, 30 Jun 2017 20:04:30 GMT):
I have a valid bna file that I have deployed many times to multiple versions of fabric, but the new composer playground refuses to import it, claiming that one of my transactions has "more than one field with name (transactionId)". Anybody know why?

jdockter (Fri, 30 Jun 2017 20:06:38 GMT):
@dwakeman looks like the 0.9 release had changes to transactionId and eventId being used, see the release notes here, https://github.com/hyperledger/composer/releases/tag/v0.9.0

dwakeman (Fri, 30 Jun 2017 20:08:38 GMT):
Interesting. I removed them all and then it complained that they were missing.

dwakeman (Fri, 30 Jun 2017 20:16:28 GMT):
When I try to run npm install to build the archive, I get this error: ```> pharma-network@0.6.2 prepublish /Users/dwakeman/git/pharma-network > mkdirp ./dist && composer archive create --sourceType dir --sourceName . -a ./dist/pharma-network.bna Creating Business Network Archive Looking for package.json of Business Network Definition Input directory: /Users/dwakeman/git/pharma-network /Users/dwakeman/git/pharma-network/node_modules/composer-cli/node_modules/yargs/yargs.js:1079 else throw err ^ IllegalModelException: Class ApproveMedication is not declared as abstract.

dwakeman (Fri, 30 Jun 2017 20:17:43 GMT):
do I need to explicitly state that my transaction `extends org.hyperledger.composer.system.Transaction`?

dwakeman (Fri, 30 Jun 2017 20:19:15 GMT):
or is there something I need to update in my package.json?

davidkel (Fri, 30 Jun 2017 21:27:31 GMT):
@dwakeman I would say that given this wide spread api change, you need to check that all you composer references are in sync. So if you are using playground 0.9.0 make sure that the cli, rest server as also at that level and any client applications also reference the latest level in package.json. If not then one part is going to have no problems while others will report issues.

dwakeman (Fri, 30 Jun 2017 21:28:31 GMT):
I am using playground in bluemix, and my composer is at this level: ```composer-cli v0.9.0 composer-admin v0.9.0 composer-client v0.9.0 composer-common v0.9.0 composer-runtime-hlf v0.9.0 composer-runtime-hlfv1 v0.9.0```

dwakeman (Fri, 30 Jun 2017 21:29:12 GMT):
I followed the developer tutorial earlier in the week so I have that setup. And I think I know what the issue is.......

dwakeman (Fri, 30 Jun 2017 21:31:49 GMT):
dang, nope. I had the engine in the package.json set to "^0.7.4" but changing it to "0.9.0" didn't fix it.

dwakeman (Fri, 30 Jun 2017 21:32:22 GMT):
i am just trying to do npm install which runs composer archive create

davidkel (Fri, 30 Jun 2017 21:33:45 GMT):
@dwakeman hmm, I was going to suggest that maybe it's worth deleting your node_modules directory and redo npm install to ensure, but if the problem is using the composer cli that obviously won't help

dwakeman (Fri, 30 Jun 2017 21:34:00 GMT):
actually, I will try that....

davidkel (Fri, 30 Jun 2017 21:35:01 GMT):
@dwakeman thinking about it, it might help :-)

dwakeman (Fri, 30 Jun 2017 21:36:45 GMT):
BRILLIANT!!!

dwakeman (Fri, 30 Jun 2017 21:37:30 GMT):
that was it! I keep forgetting that there is code in there that is specific to my business network. Might be something good to add as a tip in the docs.

davidkel (Fri, 30 Jun 2017 21:38:29 GMT):
@dwakeman could you raise it on Stack Overflow ? I think that would be a good place to put it

dwakeman (Fri, 30 Jun 2017 22:08:06 GMT):
@davidkel question posted and answered, but one other thought occurred to me. I already had my project in github and was using vscode to edit it, so i had no problem making edits to the model to meet the new API requirements. What happens to people who just use playground and export/import bna files? They're going to be stuck because they can't import the bna file to make the edits. They can still rename the bna file to a zip file, unzip it, fix the code and use `composer archive create` to build it again, but that's a bit of work. Couldn't the playground still let you import it, even though it's not valid for deployment?

dselman (Fri, 30 Jun 2017 23:47:33 GMT):
@SahilKapoor are you using the Swagger UI to test that POST request?

dselman (Fri, 30 Jun 2017 23:50:02 GMT):
I suspect you need to replace your `.` with `_` in your POST request

Vipul_Bajaj (Sat, 01 Jul 2017 05:10:03 GMT):
Can anyone help me out with this? https://chat.hyperledger.org/channel/composer?msg=7vcwLLwGTpkgaLDNB

davidkel (Sat, 01 Jul 2017 07:26:13 GMT):
@Vipul_Bajaj you could try `export DEBUG=composer:* ` then rerun the rest server and pipe the console output to a file (or use `tee` ) and see if there is any hint to the problem in the log output

dselman (Sat, 01 Jul 2017 10:11:31 GMT):
Have you unit tested this logic outside of Fabric?

dselman (Sat, 01 Jul 2017 10:12:53 GMT):
Note that relationships are not currently resolved by the ACL engine, so `r.worksID.agent.getIdentifier()` looks suspiciously like you are trying to traverse a relationship

To test, try replacing this with (true) and see it it works

sstone1 (Sat, 01 Jul 2017 11:19:36 GMT):
@baoyangc you should not use `new Date` from within a transaction processor function; it will make your business logic non-deterministic. if this code is run by multiple endorsing peers running on different machines, then each peer will come up with a different date/time. if you need to use the date/time, then you should pass it in from the client side.

baoyangc (Sat, 01 Jul 2017 11:25:34 GMT):
the type of buyer and seller is the same. so the buyer should be write as:resource:org.bqj.BanquanjiaUser#chai2

sstone1 (Sat, 01 Jul 2017 11:29:32 GMT):
the error should be that the `org.bqj` namespace doesn't exist

This usually means that composer failed to install correctly, usually because you are using an unsupported version of npm/node or OS.

dselman (Sun, 02 Jul 2017 08:20:40 GMT):
best thing is to rerun `npm uninstall -g composer-cli` followed by `npm install -g composer-cli` carefully checking that the install didn't raise any errors

@iconisaa I could be wrong based on font being used but it looks to me like you are specifying profile 'h1fv1' when you should be using `hlfv1` (ie you have replaced the 'el' with a 'one' which means it isn't the correct profile name)

is there exist an example of an nodejs application, that runs adminConnection.connect(..) with hlfv1 module connector, (not CLI Command) ?

dselman (Sun, 02 Jul 2017 09:12:17 GMT):
Lots of the unit tests for business networks use the AdminConnection. They zip up the BNA and deploy it before running the unit test. E.g. https://github.com/hyperledger/composer-sample-networks/blob/master/packages/perishable-network/test/perishable.js

wael (Sun, 02 Jul 2017 09:43:47 GMT):
@dselman right, the unit tests uses adminConnection and it works for embedded just like what I did, but when I try to deploy to hlfv1 it doesn't work..

wael (Sun, 02 Jul 2017 09:44:15 GMT):
I tried to many

dselman (Sun, 02 Jul 2017 09:44:35 GMT):
It should. Just reference a connection profile that exists (e.g. `hlfv1` and use the right credentials (e.g. `PeerAdmin`).

dselman (Sun, 02 Jul 2017 09:45:00 GMT):
Can you paste your code?

dselman (Sun, 02 Jul 2017 09:45:19 GMT):
The CLI just wraps this API...

wael (Sun, 02 Jul 2017 09:45:54 GMT):
@dselman yes I tried this also have the same problem, also re install composer-cli, re-install npm , and installing python 2.7 , ..

dselman (Sun, 02 Jul 2017 09:46:27 GMT):
can you create a question on StackOverflow please and attach as much info as you can

wael (Sun, 02 Jul 2017 09:47:47 GMT):
const admin = { type: "hlfv1", orderers: [{ url: "grpc://localhost:7050" }], ca: "http://localhost:7054", peers: [{ requestURL: "grpc://localhost:7051", eventURL: "grpc://localhost:7053" }, { requestURL: "grpc://localhost:7056", eventURL: "grpc://localhost:7058" } ], keyValStore: "/Users/waels/.hfc-key-store", channel: "mychannel", mspID: "Org1MSP", deployWaitTime: "300", invokeWaitTime: "100" } const adminConnection = new AdminConnection(); adminConnection.createProfile('hlfv1', admin).then(() => { adminConnection.getAllProfiles() }) .then(() => { adminConnection.connect('hlfv1', 'PeerAdmin', 'adminpw').then(() => {}, function(err) { console.log(err); }) });

@wael Your application has no dependency on composer-cli so unfortunately uninstalling and installing composer-cli isn't going to help. Have you tried deleting the node_modules directory where your application is and re-running npm install to re-install the dependencies for your application ?

wael (Sun, 02 Jul 2017 12:03:37 GMT):
@davidkel I have npm install in the directory of my network which my package.json in that directory is this

davidkel (Sun, 02 Jul 2017 12:04:07 GMT):
@wael but have you tried deleting the node_modules directory first ?

wael (Sun, 02 Jul 2017 12:04:17 GMT):
yes offcourse

wael (Sun, 02 Jul 2017 12:04:35 GMT):
but it's not related to my business network yet ..

wael (Sun, 02 Jul 2017 12:04:45 GMT):
I am just want to connect adminConnection to the profile

wael (Sun, 02 Jul 2017 12:04:57 GMT):
then I will deploy the business network

wael (Sun, 02 Jul 2017 12:05:31 GMT):
I am working on the client side , there I make the adminConnection , and then connect to the business network\

davidkel (Sun, 02 Jul 2017 12:05:38 GMT):
@wael and you still get `unable to load composer-connector-hlfv1` ?

wael (Sun, 02 Jul 2017 12:05:51 GMT):
yes

davidkel (Sun, 02 Jul 2017 12:06:16 GMT):
@wael but the composer-cli works without a problem ?

wael (Sun, 02 Jul 2017 12:06:52 GMT):
my package.json at the client where I do the adminConnection is : "dependencies": { "request": "^2.81.0", "q": "^1.5.0", "cli-table": "^0.3.1", "composer-cli": "^0.9.0-0", "composer-client": "^0.9.0-0", "fabric-ca-client": "1.0.0-alpha.1", "fabric-client": "1.0.0-alpha.1", "homedir": "^0.6.0", "config": "^1.24.0", "digitalproperty-network": "^0.1.0-0", "jsonfile": "^2.4.0", "lodash": "^4.17.4", "prettyjson": "^1.2.1", "sprintf-js": "^1.0.3", "winston": "^2.3.0", "yargs": "^6.5.0" }, "devDependencies": { "mocha": "^3.2.0", "sinon": "^2.1.0", "supertest": "^3.0.0", "browserfs": "^1.2.0", "chai": "^3.5.0", "chai-as-promised": "^6.0.0", "composer-admin": "latest", "composer-cli": "latest", "composer-client": "latest", "composer-connector-embedded": "latest", "composer-connector-hlfv1": "latest" }

wael (Sun, 02 Jul 2017 12:07:12 GMT):
the composer-cli works fine , and when I use the CLI is works also ..

davidkel (Sun, 02 Jul 2017 12:08:12 GMT):
@wael I would suggest taking out 'composer-cli' and 'composer-connector-hlfv1' from your package.json, deleting node_modules and doing an npm install again

wael (Sun, 02 Jul 2017 12:08:41 GMT):
and then taking them back ?

davidkel (Sun, 02 Jul 2017 12:09:53 GMT):
@wael your application will never depend on 'composer-cli' as it is a command line tool, not an api. 'composer-connector-hlfv1' is referenced by composer-admin so will be pulled in automatically

wael (Sun, 02 Jul 2017 12:10:53 GMT):
so you suggest to run with "devDependencies": { "mocha": "^3.2.0", "sinon": "^2.1.0", "supertest": "^3.0.0", "browserfs": "^1.2.0", "chai": "^3.5.0", "chai-as-promised": "^6.0.0", "composer-admin": "latest", "composer-client": "latest", "composer-connector-embedded": "latest" } ?

davidkel (Sun, 02 Jul 2017 12:15:02 GMT):
``` dependencies": { "request": "^2.81.0", "q": "^1.5.0", "cli-table": "^0.3.1", "composer-client": "0.7.5", "composer-admin": "0.7.5", "homedir": "^0.6.0", "config": "^1.24.0", "digitalproperty-network": "^0.1.0-0", "jsonfile": "^2.4.0", "lodash": "^4.17.4", "prettyjson": "^1.2.1", "sprintf-js": "^1.0.3", "winston": "^2.3.0", "yargs": "^6.5.0" }, "devDependencies": { "mocha": "^3.2.0", "sinon": "^2.1.0", "supertest": "^3.0.0", "browserfs": "^1.2.0", "chai": "^3.5.0", "chai-as-promised": "^6.0.0" } ``` ok, had a more detailed look at your package.json and recommend you do this, especially as it appears you want to talk to hlfv1 1.0.0-alpha1 you must use 0.7.5 version of composer

wael (Sun, 02 Jul 2017 12:15:48 GMT):
my composer version 0.9.0

wael (Sun, 02 Jul 2017 12:16:05 GMT):
I will try with these dependencies

davidkel (Sun, 02 Jul 2017 12:16:26 GMT):
@wael What version of hyperledger fabric are you trying to work with ?

wael (Sun, 02 Jul 2017 12:17:28 GMT):
which command check fabric version ?

davidkel (Sun, 02 Jul 2017 12:17:36 GMT):
@wael docker ps

wael (Sun, 02 Jul 2017 12:17:56 GMT):

wael (Sun, 02 Jul 2017 12:18:18 GMT):
x86_64-1.0.0-alpha ****

wael (Sun, 02 Jul 2017 12:18:28 GMT):
beta I was using for couchdb

davidkel (Sun, 02 Jul 2017 12:18:42 GMT):
ok, then use this one ``` dependencies": { "request": "^2.81.0", "q": "^1.5.0", "cli-table": "^0.3.1", "composer-client": "0.9.0", "composer-admin": "0.9.0", "homedir": "^0.6.0", "config": "^1.24.0", "digitalproperty-network": "^0.1.0-0", "jsonfile": "^2.4.0", "lodash": "^4.17.4", "prettyjson": "^1.2.1", "sprintf-js": "^1.0.3", "winston": "^2.3.0", "yargs": "^6.5.0" }, "devDependencies": { "mocha": "^3.2.0", "sinon": "^2.1.0", "supertest": "^3.0.0", "browserfs": "^1.2.0", "chai": "^3.5.0", "chai-as-promised": "^6.0.0" } ``` ie use composer 0.9.0 modules

wael (Sun, 02 Jul 2017 12:24:56 GMT):
@davidkel unfortunately, the same

davidkel (Sun, 02 Jul 2017 12:25:42 GMT):
@wael just to confirm that you did delete node_modules directory completely first ?

wael (Sun, 02 Jul 2017 12:25:52 GMT):
yes offcourse

wael (Sun, 02 Jul 2017 12:28:17 GMT):
I use the docker-compose for my angular2 application, and when I reach the client side where I had put this package.json to connect the adminConnection it gives me that error.

Hi there, If we specify multiple peers in our connection.json, when the client invokes a transaction, does it attempt to connect to a single endorsement peer or multiple peers and if one or more peers are not available, does the connection attempt to connect to a different peer). If I am coding my client code, I am wondering if I need to add any sort of retry logic if one of the peers is not available or is this handled by the Composer code? Thanks!

hey is it possible to retrieve the chaincode once the bna is deployed?

Pere-Lluis (Mon, 03 Jul 2017 10:40:00 GMT):
kind of getting chaincode from a .bna

sstone1 (Mon, 03 Jul 2017 11:10:56 GMT):
@Pere-Lluis there is no chaincode generated when you deploy a BNA

sstone1 (Mon, 03 Jul 2017 11:11:23 GMT):
e.g. Composer does not compile your BNA into a chaincode and deploy that

sstone1 (Mon, 03 Jul 2017 11:11:35 GMT):
the BNA gets deployed along with a generic piece of chaincode we call the Composer runtime

Pere-Lluis (Mon, 03 Jul 2017 11:12:41 GMT):
oh okey, so fabric-sdk won't work with the deployed bna

Pere-Lluis (Mon, 03 Jul 2017 11:12:58 GMT):
like trying transactions using it

sstone1 (Mon, 03 Jul 2017 11:13:17 GMT):
no - you can still use the fabric-sdk to make calls to the deployed BNA - it's still a normal running chaincode from the Fabric point of view

sstone1 (Mon, 03 Jul 2017 11:13:34 GMT):
but you need to understand our chaincode interface which is not documented - it's all in the code

sstone1 (Mon, 03 Jul 2017 11:13:41 GMT):
this is why we provide the Composer client API

sstone1 (Mon, 03 Jul 2017 11:13:45 GMT):
why can't you use that?

mahoney1 (Mon, 03 Jul 2017 11:46:57 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=28KMws24uk2euTsFN) @rama_rahul the sample Angular app is a skeleton app that you can modify as a project to start adding transactions from it.. Your Angular app can use RESTful APIs to connect to the Composer REST server where the APis are already published for your business network (assets, participants, transactions etc), in this case the Commodity Trading sample network. REST APIs provides a useful layer of language-neutral abstraction.

@ShobhanaSundararaman would suggest to use the docs for guidance https://hyperledger.github.io/composer/unstable/tutorials/developer-guide.html and copying latest snippets from to recreate your sample environment (this tutorial reflects the fact that your composer modules need to be at the latest which is v0.9.0 - sounds like you have this build).

davidkel (Mon, 03 Jul 2017 12:29:50 GMT):
@tennenjl no, there isn't any retry logic, composer does check the response from the peer is valid and also that all the responses from all the peers agree (although that might have to change once we support endorsement policies)

dselman (Mon, 03 Jul 2017 12:30:32 GMT):
@arner @mahoney1 this is a bug in Playground (fixed already in unstable). To workaround you should build the BNA locally (using npm install / test) and then import the BNA file. Playground doesn't like the .eslintrc.yml in the scripts dir.

[ ](https://chat.hyperledger.org/channel/composer?msg=H3uzJ8wTLn2evjSkN) @SahilKapoor You need to update the composer version to v0.9.0. command: npm install -g composer-cli Ref: https://hyperledger.github.io/composer/installing/development-tools.html

SahilKapoor (Mon, 03 Jul 2017 12:44:15 GMT):
It is 0.9

SahilKapoor (Mon, 03 Jul 2017 12:44:15 GMT):
It is 0.9 and I think absatract transaction and asset were introduced in v0.9. If it wasn't 0.9 then I think it would not had thrown this error.

dselman (Mon, 03 Jul 2017 12:45:42 GMT):
@arner you can use unstable if you want to test the fix: https://composer-playground-unstable.mybluemix.net/ It should import the pii-network.

geoms (Mon, 03 Jul 2017 13:04:06 GMT):
@SahilKapoor Its working for me after upgrading to v0.9.0 in another sample project - "my network".

geoms (Mon, 03 Jul 2017 13:05:24 GMT):
As per the release note https://github.com/hyperledger/composer/releases/tag/v0.9.0

geoms (Mon, 03 Jul 2017 13:05:33 GMT):
you need check below points

geoms (Mon, 03 Jul 2017 13:05:34 GMT):
The impact of this change is that any user defined transactions and/or events that have a 'transactionId' or 'eventId' or 'timestamp' will need to be removed. the network archive will need to be updated as a result ACLs might need to be updated if the current ACLs do not specifically include an allow for any type.

mahoney1 (Mon, 03 Jul 2017 13:21:07 GMT):
@SahilKapoor - I've imported the vehicle lifecycle business network definition into playground and that model (ie models/org.acme.vehicle.lifecycle.manufacturer.cto) is checking out OK, no errors. Have you a local playground installed and at v0.9.0? As for the vehicle-lifecycle.bna - you can download file to test here (.bna file) -> https://github.com/hyperledger/composer-sample-applications/tree/master/packages/vehicle-lifecycle

[ ](https://chat.hyperledger.org/channel/composer?msg=3KoAZnJZMuxcZH6CD) @baoyangc looks like your current composer runtime (v.9.0) is running against an earlier deployed chaincode. You will need to teardown the docker Fabric containers and deploy the business network you're working with

[ ](https://chat.hyperledger.org/channel/composer?msg=8bajAyx9btzQQNX7H) @benjaminverhaegen per the example, you select 'Skeleton Business Network' , then your model file (eg. org.acme.biznet.cto) is created in the subdirectory 'models' - to create an archive for deploying its `composer archive create --sourceType dir --sourceName . -a my-network.bna`

baoyangc (Mon, 03 Jul 2017 17:01:49 GMT):
after run composer-rest-server , we got an http server with rest api. through this api, wo can do delete,put operation on an asset. we also can do transaction to change an property of an asset. so when i change a property of an asset with PUT request, does this have difference with do transaction to change a property of this asset

baoyangc (Mon, 03 Jul 2017 17:03:07 GMT):
i think all write operation on state db are an transaction

baoyangc (Mon, 03 Jul 2017 17:03:16 GMT):
isn't it?

[ ](https://chat.hyperledger.org/channel/composer?msg=dhYk869DLiwmKxCDu) @baoyangc yes, ultimately that REST operation results in a blockchain transaction, composer generates the necessary chaincode to be executed on the Hyperledger Fabric blockchain to change the world state.

do i just define function init() in logic.js?

davidkel (Mon, 03 Jul 2017 17:42:55 GMT):
@gen_el there is no init facility. Can you provide some more information about why you think you might need one ?

gen_el (Mon, 03 Jul 2017 18:12:03 GMT):
@davidkel I am deploying a chain code on a channel strictly for 2 organisations for control reasons. However, for the chain code to work it requires some state data that will be inserted at deployment time. This data will vary from channel to channel.

gen_el (Mon, 03 Jul 2017 18:13:47 GMT):
@davidkel So how do i get this state data in at any other time except instantiation of the chain code. This data will be pulled from a central configuration mgmt server.

Hi guys, trying to connect onto a business network through `ca` but I’m getting the following error: ``` Fatal server error: { Error: error trying login and get user Context. Error: error trying to enroll user. Error: Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 127.0.0.1:8054] ``` Does this mean that I can’t connect to the `ca` service all together or is it refusing connection based on authentication? Heres is my `connection.json` for reference: ``` { "type": "hlfv1", "orderers": [ { "url": "grpc://localhost:7050" } ], "ca": { "url": "http://localhost:8054", "name": "ca.org1.example.com" }, "peers": [ { "requestURL": "grpc://localhost:7051", "eventURL": "grpc://localhost:7053" } ], "keyValStore": "/root/.composer-connection-profiles/test_bpapiv1/credentials", "channel": "mychannel", "mspID": "Org1MSP", "timeout": "300" } ```

[ ](https://chat.hyperledger.org/channel/composer?msg=FSa5KHAdAQCffGDJa) @rodders1991 it means nothing is listening on localhost:8054 - is this the port your CA server is listening on? Normally in such a sample connection.json, it is "http://localhost:7054" but you will know better -) - (Also, FYI composer modules should be installed as a non-root user).

davidkel (Mon, 03 Jul 2017 21:15:18 GMT):
@gen_el One possible approach could be to model an init transaction which can only be called once. You could then create a client application that deploys the business network and then drives the transaction, passing in the data you want.

Quick question, when we deploy the bna it gets deployed on one peer

Pere-Lluis (Tue, 04 Jul 2017 07:58:13 GMT):
and a docker with it is created

Pere-Lluis (Tue, 04 Jul 2017 07:58:20 GMT):
how can we deploy it to the other peers?

davidkel (Tue, 04 Jul 2017 07:58:40 GMT):
@wael release notes can be found here https://github.com/hyperledger/composer/releases/tag/v0.9.0 note that there are breaking changes

Pere-Lluis (Tue, 04 Jul 2017 07:58:44 GMT):
I tried changing the globals and deploying again but didn't work

Pere-Lluis (Tue, 04 Jul 2017 07:59:11 GMT):
(I have already joined the channel with the rest)

davidkel (Tue, 04 Jul 2017 08:00:52 GMT):
@Pere-Lluis when you deploy it will deploy to the list of peers in your connection profile. A connection profile can contain more than 1 peer definition

Pere-Lluis (Tue, 04 Jul 2017 08:01:21 GMT):
oh okey thanks

Pere-Lluis (Tue, 04 Jul 2017 08:03:39 GMT):
humm should I do it for different MSP ID one at a time?

davidkel (Tue, 04 Jul 2017 08:05:12 GMT):
@karthikworks what version of the composer rest server are you running ? to find out use `npm list -g --depth=0 | grep composer-rest-server`

davidkel (Tue, 04 Jul 2017 08:05:47 GMT):
@Pere-Lluis yes, in a real world example you would only ever deploy to your own organisation's peers

Pere-Lluis (Tue, 04 Jul 2017 08:06:06 GMT):
makes sense, thanks!

Pere-Lluis (Tue, 04 Jul 2017 08:09:49 GMT):
I think that belongs to #fabric or #fabric-questions

Pere-Lluis (Tue, 04 Jul 2017 08:10:31 GMT):
oh u mean the startFabric from composer tutorial right? @VimalkumarNair

VimalkumarNair (Tue, 04 Jul 2017 08:11:31 GMT):
@Pere-Lluis yes i am following the composer tutorial..

Pere-Lluis (Tue, 04 Jul 2017 08:11:52 GMT):
try with sudo, it solved it for some people

Pere-Lluis (Tue, 04 Jul 2017 08:12:31 GMT):
@davidkel I added the peers but somehow they are not getting the bna deployed

Pere-Lluis (Tue, 04 Jul 2017 08:12:37 GMT):
is there anything else needed?

davidkel (Tue, 04 Jul 2017 08:13:22 GMT):
@Pere-Lluis did the command complete successfully ?

Pere-Lluis (Tue, 04 Jul 2017 08:13:29 GMT):
yes

wael (Tue, 04 Jul 2017 08:13:46 GMT):
@davidkel I read them , there isn't another changes right ?

Pere-Lluis (Tue, 04 Jul 2017 08:14:11 GMT):
@davidkel maybe I have to start over, but it should work even if it's already deployed in one of them right?

davidkel (Tue, 04 Jul 2017 08:14:38 GMT):
@Pere-Lluis I assume the command completed successfully then ?

VimalkumarNair (Tue, 04 Jul 2017 08:14:49 GMT):
@Pere-Lluis Its working for me....thanks:slight_smile:

Pere-Lluis (Tue, 04 Jul 2017 08:15:04 GMT):
@davidkel yep, the usual, command succeded

Pere-Lluis (Tue, 04 Jul 2017 08:15:06 GMT):
and the tick

davidkel (Tue, 04 Jul 2017 08:15:26 GMT):
@Pere-Lluis then the bna has been deployed successfully to those peers.

Pere-Lluis (Tue, 04 Jul 2017 08:15:43 GMT):
even if a docker hasn't been created?

Pere-Lluis (Tue, 04 Jul 2017 08:15:58 GMT):
with the dev-peer1...etc?

davidkel (Tue, 04 Jul 2017 08:16:10 GMT):
@Pere-Lluis yes, when you send a request to those peers, the docker container is then started

Pere-Lluis (Tue, 04 Jul 2017 08:16:39 GMT):
okey, I'll try thanks @davidkel

davidkel (Tue, 04 Jul 2017 08:18:21 GMT):
@wael no other changes that I am aware of, check your cto & transaction logic are valid though as it may be the cause. If it isn't valid and it was the cause then please raise an issue to describe as maybe composer isn't outputting an appropriate error

Pere-Lluis (Tue, 04 Jul 2017 08:19:45 GMT):
@VimalkumarNair You are welcomne!

Pere-Lluis (Tue, 04 Jul 2017 08:20:17 GMT):

mattalhonte (Tue, 04 Jul 2017 09:19:37 GMT):
@jaguarg You have to add them with a request o the REST API, then they'll show up and you'll be able to have them to transactions.

davidkel (Tue, 04 Jul 2017 09:31:18 GMT):
@jpuentea The error means you cannot connect to your fabric. Is it running ? If it is are you running on a provisioned local machine ?

davidkel (Tue, 04 Jul 2017 09:33:30 GMT):
@karthikworks That error can happen is you are running old versions of composer. If you aren't and it looks like you aren't then the userid you have chosen isn't valid to connect to the peer or one of the peers you have defined in your connection profile

uber.twin (Tue, 04 Jul 2017 09:45:09 GMT):
@davidkel hi, are there any ACL capabilities for controlling the access for the bizNetworkConnection.issueIdentity() operation?

sstone1 (Tue, 04 Jul 2017 09:51:31 GMT):
@uber.twin not yet, this is work planned to happen soon under https://github.com/hyperledger/composer/issues/722

sstone1 (Tue, 04 Jul 2017 09:51:47 GMT):
note that the fabric CA has controls over who can issue identities which do apply in the mean time

uber.twin (Tue, 04 Jul 2017 09:53:57 GMT):
ok, I will look into that

uber.twin (Tue, 04 Jul 2017 09:54:20 GMT):
@sstone1 I was asking because I tried to incorporate an apparently inoffensive rule, as bellow ``` rule PartyGuard { description: "ACL" participant: "my.Party" operation: ALL resource: "my.Party" action: ALLOW } ```

uber.twin (Tue, 04 Jul 2017 09:54:59 GMT):
now, my PeerAdmin participant can't call .issueIdentity()

uber.twin (Tue, 04 Jul 2017 09:55:31 GMT):
this is the error message : Error: fabric-ca request register failed with errors [[{"code":400,"message":"Authorization failure"}]]

uber.twin (Tue, 04 Jul 2017 09:57:02 GMT):
any type of asset creation works as before

sstone1 (Tue, 04 Jul 2017 09:57:08 GMT):
PeerAdmin cannot use the CA to issue identities

sstone1 (Tue, 04 Jul 2017 09:57:29 GMT):
you must use the `admin` / `adminpw` ID with the CA to issue identities

Pere-Lluis (Tue, 04 Jul 2017 09:58:58 GMT):
I got the local playground problem where it shows the whale saying Get local Version again

Pere-Lluis (Tue, 04 Jul 2017 09:59:27 GMT):

Hey guys the update of the ACL syntax hit me. Could you please help me with the following problem?: When I use the old syntax the modelbinding validator throws an error (couldnt find namespace ...) so I changed the ACL file to fit the new syntax. However when using the new syntax I get the following error when running composer network deploy: ParseException: Expected identifier but "*" found. Line 20 column 46 Is there some update command I am missing?

germanhs (Tue, 04 Jul 2017 10:04:06 GMT):
Because the validator seems to be updated but not my composer network deploy command.

uber.twin (Tue, 04 Jul 2017 10:10:30 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Hasqs9C2CTaFmGFwa) @sstone1 right, I just verified it. noticed the "admin" party can't deploy a network though(PeerAdmin can) Is there a complete description of the roles assigned for these two participants?

sstone1 (Tue, 04 Jul 2017 10:11:41 GMT):
those are not really participants - they are Fabric IDs with permissions to perform Fabric operations

sstone1 (Tue, 04 Jul 2017 10:11:58 GMT):
PeerAdmin is the administrator of a peer, who is authorized to install and possibly instantiate chaincode

sstone1 (Tue, 04 Jul 2017 10:12:13 GMT):
admin is the default user for a Fabric CA, who is authorized to invoke chaincode

sstone1 (Tue, 04 Jul 2017 10:14:26 GMT):
@Pere-Lluis the error shows that the Fabric CA is not running at `ca.example.com`. is it running? can you see it in the output of `docker ps`?

Pere-Lluis (Tue, 04 Jul 2017 10:14:34 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=kiJ4qGmvTCtCbrrST) @Pere-Lluis It looks like it's using a hlfabric when it should be hlvf1, but I can't acces to the profiles since it says I'm not running it locally

Pere-Lluis (Tue, 04 Jul 2017 10:14:42 GMT):
it's running diferent CA

Pere-Lluis (Tue, 04 Jul 2017 10:15:00 GMT):
ca_peerOrg1

Pere-Lluis (Tue, 04 Jul 2017 10:15:05 GMT):
and ca_peerOrg2

sstone1 (Tue, 04 Jul 2017 10:15:13 GMT):
@germanhs run `composer -v` and see what version is printed out. if it's an old one, uninstall first `npm uninstall -g composer-cli` and then install it again `npm install -g composer-cli`

Pere-Lluis (Tue, 04 Jul 2017 10:18:58 GMT):
It still looks for a ca.example.com, is it necessary to be a CA with that name running ffor playground?

Pere-Lluis (Tue, 04 Jul 2017 10:22:09 GMT):
can we change the connection profile it's using by default? maybe that's the problem

Pere-Lluis (Tue, 04 Jul 2017 10:33:24 GMT):

The transaction model only has the fields: txId, serialnum, productname. there isnt even a field named transactionId,

sstone1 (Tue, 04 Jul 2017 10:40:33 GMT):
@Pere-Lluis you may just need to clear your browser local storage, which should wipe any old connection profiles you have in the browser

sstone1 (Tue, 04 Jul 2017 10:40:42 GMT):
@germanhs how are you creating this transaction?

germanhs (Tue, 04 Jul 2017 10:41:18 GMT):
@sstone1 via command line

germanhs (Tue, 04 Jul 2017 10:41:43 GMT):
its a bash script which generates test data after deploying the network. It worked before but now I got this error.

germanhs (Tue, 04 Jul 2017 10:42:01 GMT):
So no browser storage as this script runs on the ubuntu VM of the rest server

transaction CreateTuna identified by txId { o String txId o String serialnumber default = "0001" o String productName }

sstone1 (Tue, 04 Jul 2017 10:43:52 GMT):
right - you need to remove the `identified by txId` and the `o String txId` if you are using v0.9.0

germanhs (Tue, 04 Jul 2017 10:44:17 GMT):
ah okay but only for transactions?

baoyangc (Tue, 04 Jul 2017 10:58:39 GMT):
but when i make ping with chaiAdmin, it response me that "role" is null

baoyangc (Tue, 04 Jul 2017 11:01:43 GMT):
the command line response is ``` composer network ping -p hlfv1 -n 'banquanjia' -i chai2Admin -s ePZuyomuRRPQ The connection to the network was successfully tested: banquanjia version: 0.9.0 participant: Command succeeded```

baoyangc (Tue, 04 Jul 2017 11:02:14 GMT):
`composer identity issue -p hlfv1 -n 'banquanjia' -i admin -s 'adminpw' -u chai2Admin -a "org.bqj.cn.BanquanjiaAdmin#chai2Admin"`

sstone1 (Tue, 04 Jul 2017 11:02:46 GMT):
@baoyangc not at the moment; we're working on removing that limitation

baoyangc (Tue, 04 Jul 2017 11:03:14 GMT):
what's the limitation?

Pere-Lluis (Tue, 04 Jul 2017 11:05:45 GMT):
@sstone1 to sum up, I don't know if this is expected behavior, but if you have a wrong connection profile in local storage and it tries to connect and fails, the composer playground shows the Get Local Version instead of the globe, and then it doens't let you change the profile unless you clear storage

Pere-Lluis (Tue, 04 Jul 2017 11:06:03 GMT):
it's not a big deal, but maybe confusing for beginners like me

sstone1 (Tue, 04 Jul 2017 11:06:41 GMT):
yeah, it's not ideal - can you raise an issue on GitHub for it? you should be able to repair the connection profile in order to connect

sstone1 (Tue, 04 Jul 2017 11:07:04 GMT):
@baoyangc any IDs with `admin` in (case insensitive) get treated as a "superuser"

sstone1 (Tue, 04 Jul 2017 11:07:19 GMT):
it will be fixed under: https://github.com/hyperledger/composer/issues/722

@Pere-Lluis that error states that you have connected to a ca, but the name you have specified in the connection profile is not known to that ca server. You need to make sure the name you give in the connection profile is the name registered with that ca. The names registered with the CA are part of the CA configuration you specified

Pere-Lluis (Tue, 04 Jul 2017 12:03:08 GMT):
@davidkel Thanks david, but the name has to be the same everywhere right?

Pere-Lluis (Tue, 04 Jul 2017 12:03:22 GMT):
the connection profile has the same name as the container

Pere-Lluis (Tue, 04 Jul 2017 12:03:40 GMT):
or is it another name it references to?

davidkel (Tue, 04 Jul 2017 12:04:09 GMT):
The container name is not the name registered to the CA. Your CA configuration will have defined 1 or more names for that CA Server

Pere-Lluis (Tue, 04 Jul 2017 12:04:12 GMT):
@VimalkumarNair I had a similar problem and it was due to not having properly started the channel

Pere-Lluis (Tue, 04 Jul 2017 12:04:39 GMT):
Oh okey, and where is that CA configuration defined?

Pere-Lluis (Tue, 04 Jul 2017 12:05:12 GMT):
in the yaml?

davidkel (Tue, 04 Jul 2017 12:05:37 GMT):
That really depends on how you run the CA. Environment variables can define CA configuration as well as a specific CA yaml file

Pere-Lluis (Tue, 04 Jul 2017 12:05:39 GMT):
like this: - FABRIC_CA_SERVER_CA_NAME=ca-org1 ?

davidkel (Tue, 04 Jul 2017 12:06:06 GMT):
Yep, thats an environment variable for the CA

Pere-Lluis (Tue, 04 Jul 2017 12:06:08 GMT):
I think it's there, thank you, I confused the name of the server with the conainers

Pere-Lluis (Tue, 04 Jul 2017 12:06:15 GMT):
will try now, thank you

Pere-Lluis (Tue, 04 Jul 2017 12:07:31 GMT):

hi guys, just started exploring composer. i understand that that composer-rest-server uses the loopback framework to expose rest APIs automatically. in loopback framework we can publish customized APIs (via remote methods) and/or add additional logic to existing methods by using remote hooks. may i know how we do this in the context of composer-rest-server?

@sstone1 : while running ./startFabric.sh, errors are thrown asking to add few URLs in the composer folder to docker preferences. Docker preferences already have /Users added and all these URLs are present in /users folder. Earlier steps worked fine. Can you please suggest? Only difference is the git version.. i am using the latest one and not 2.9 as suggested in installation process.

@sstone1 @davidkel hi, is there a dedicate method for cleaning up a registry?

uber.twin (Tue, 04 Jul 2017 13:29:28 GMT):
something like the code bellow, times out

uber.twin (Tue, 04 Jul 2017 13:29:28 GMT):
something like the code below, times out

uber.twin (Tue, 04 Jul 2017 13:29:32 GMT):
```return registry.resolveAll() .then((objects) => { return registry.removeAll(objects); });```

jellevdp (Tue, 04 Jul 2017 13:51:19 GMT):
Hi - I'm struggling a bit with querying chaincode that I have created with composer and could use some help or a good example (on the github all the query examples seem to be deleted?). I'm running HL v0.6 and have a very simple smart contract with just one type of asset with one attribute called value that I want to store. Going over the docs only shows queries in a HLFv1 runtime. What is the right way to do this with composer & HL v0.6 ? Are there any examples available?

jellevdp (Tue, 04 Jul 2017 13:52:32 GMT):
and.. without using the composer REST server

sstone1 (Tue, 04 Jul 2017 13:57:58 GMT):
@uber.twin you don't want to use `resolveAll`, try `getAll` instead

sstone1 (Tue, 04 Jul 2017 13:58:51 GMT):
@jellevdp no, you can only query assets by their ID when using Composer with Fabric v0.6. The complex query functionality requires a backend data store that supports queries, in Fabric v1.0 this is CouchDB.

sstone1 (Tue, 04 Jul 2017 13:59:05 GMT):
your only other option is to do a `getAll` and do the filtering client side

uber.twin (Tue, 04 Jul 2017 14:00:14 GMT):
@sstone1 you are right, when using getAll, it doesn't time out

uber.twin (Tue, 04 Jul 2017 14:00:21 GMT):
thank you

sstone1 (Tue, 04 Jul 2017 14:00:25 GMT):
np

jellevdp (Tue, 04 Jul 2017 14:00:41 GMT):
@sstone1 this would be in the logic.js file like so: ``` function getAllAssets(tx) { return getAssetRegistry('io.unchain.demo.Asset') .then(function (assetRegistry) { return assetRegistry.getAll(); }) } ```

Pere-Lluis (Tue, 04 Jul 2017 14:01:12 GMT):
I'm still struggling with playground in Local Version trying to connect to a running Connection Profile. It asks me for an identity when I try to use the profile, but no matter which one (admin:adminpw, PeerAdmin:password or one I created with a Participant) I use, it doesn't work

Pere-Lluis (Tue, 04 Jul 2017 14:01:56 GMT):
It gives me a: Error: error trying login and get user Context. Error: error trying to enroll user. Error: Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 127.0.0.1:7054]

sstone1 (Tue, 04 Jul 2017 14:02:50 GMT):
@jellevdp yes, that's it. is that in a transaction processor function though? transaction processor functions cannot return data back to the client.

sstone1 (Tue, 04 Jul 2017 14:03:10 GMT):
or are you using the result from elsewhere in the transaction processor function?

sstone1 (Tue, 04 Jul 2017 14:03:58 GMT):
@Pere-Lluis aren't you using Playground in a Docker container? in which case `localhost` is the Playground Docker container, not your host machine - you need to use the hostname/IP address of the Fabric CA Docker container that the Playground Docker container can access

jellevdp (Tue, 04 Jul 2017 14:04:36 GMT):
but then, how would I call this transaction with a regular hfc client ?

sstone1 (Tue, 04 Jul 2017 14:05:22 GMT):
you can do, but you're just making things hard for yourself - use the `composer-client` library to interact with the deployed business network

Pere-Lluis (Tue, 04 Jul 2017 14:07:45 GMT):
@sstone1 You mean using 127.0.0.1 instead of localhost?

sstone1 (Tue, 04 Jul 2017 14:08:06 GMT):
127.0.0.1 and localhost are the same thing

sstone1 (Tue, 04 Jul 2017 14:08:16 GMT):
you need to find the hostname/IP address of the Fabric CA Docker container

Pere-Lluis (Tue, 04 Jul 2017 14:08:41 GMT):
okey... Sorry my docker knowledge is limited

Pere-Lluis (Tue, 04 Jul 2017 14:08:53 GMT):
I'll try to look for it, thanks

jellevdp (Tue, 04 Jul 2017 14:08:59 GMT):
@sstone1 sry - connection is a bit messed up so some message come through and others not. That's what I was wondering.. whether the transactions defined there could actually return data. I understand that there are easier ways of doing this with composer, but in the architecture we're working with (for a demo) we only use composer to deploy the chaincode and do invocations and queries with an hfc client. I'm considering now to use the fabric-boilerplate instead to and do a query transaction the 'old fashioned way'. Thanks for the help though Simon.

jellevdp (Tue, 04 Jul 2017 14:10:41 GMT):
does make me wonder how far you're seeing composer go in terms of functionality - because in my mind it's perfect for creating the chaincode and defining the business network, but now it's also taking on functionality that requires it to run in between the client and blockchain at all times?

sstone1 (Tue, 04 Jul 2017 14:11:45 GMT):
The Composer client is a wrapper around the Fabric SDK that makes it a lot easier to consume and reduces the workload for the client application developer

sstone1 (Tue, 04 Jul 2017 14:12:14 GMT):
The Composer REST API builds on the Composer client to make it easy for anyone with a REST client to interact with a business network

sstone1 (Tue, 04 Jul 2017 14:12:30 GMT):
Our aim is to make the building of the whole Blockchain solution simpler and faster, not just the small bit in the middle

uber.twin (Tue, 04 Jul 2017 14:12:45 GMT):

alright, thank you

Pere-Lluis (Tue, 04 Jul 2017 14:18:20 GMT):
does it mean the admin is not correct? Isn't admin:adminpw an Admin?

Pere-Lluis (Tue, 04 Jul 2017 14:18:42 GMT):
(By the way thanks again, it worked changing the IP)

sstone1 (Tue, 04 Jul 2017 14:28:28 GMT):
great!

sstone1 (Tue, 04 Jul 2017 14:28:36 GMT):
admin:adminpw is not a peer admin or a channel admin

sstone1 (Tue, 04 Jul 2017 14:29:12 GMT):
i'm not really sure what kind of admin they are "officially" - but they are the first user defined in the CA, and they have the power to create other users on the CA

davidkel (Tue, 04 Jul 2017 14:36:00 GMT):
@uber.twin I would say that you have restarted your ca server but have left the credentials for admin obtained from the previous run of the ca server in your keyValStore. Depending on how the ca server is configured every restart of the server creates the admin id from scratch giving it a new certificate and keystore. This is how our dev server is configured and I am guessing that is how your ca server is configured

baoyangc (Tue, 04 Jul 2017 14:37:38 GMT):
admin:adminpw is configured when the fabric-ca is started

baoyangc (Tue, 04 Jul 2017 14:38:21 GMT):
`fabric-ca-server start --ca.certfile /etc/hyperledger/fabric-ca-server-config/org1.example.com-cert.pem --ca.keyfile /etc/hyperledger/fabric-ca-server-config/a22daf356b2aab5792ea53e35f66fccef1d7f1aa2b3a2b92dbfbf96a448ea26a_sk -b admin:adminpw -d`

uber.twin (Tue, 04 Jul 2017 14:41:58 GMT):
@davidkel you are right, I guess that's what happened. After I cleared my .hfc-key-store folder and ran the createComposerProfile, it worked again. however, It seems strage that I could use "admin" to populate registries but not to issue identities

Pere-Lluis (Tue, 04 Jul 2017 14:44:19 GMT):
@baoyangc @sstone1 yeah, I saw that admin:adminpw is defined in the CA, but then I have no idea what should I use to be able to get Playground working

davidkel (Tue, 04 Jul 2017 14:44:33 GMT):
@uber.twin In the real world CA's would not regen their bootstrap ids on restart :-)

Pere-Lluis (Tue, 04 Jul 2017 14:46:12 GMT):
cause I get this when using the running connection profile:

i recommend just use composer-rest-server with github oauth

Pere-Lluis (Tue, 04 Jul 2017 14:48:12 GMT):
I know I can use the restAPI, but I wanted to see if I could get local Playground working with my running Fabric with deployed bna

Pere-Lluis (Tue, 04 Jul 2017 14:48:46 GMT):
yes, that's what I use

Pere-Lluis (Tue, 04 Jul 2017 14:48:54 GMT):
with google oauth

Pere-Lluis (Tue, 04 Jul 2017 14:48:58 GMT):
thanks anyway

Pere-Lluis (Tue, 04 Jul 2017 14:49:46 GMT):
maybe I should leave it and try again when the new version of playground comes

Pere-Lluis (Tue, 04 Jul 2017 14:50:01 GMT):
with the changes on profiels and stuff

davidkel (Tue, 04 Jul 2017 14:58:39 GMT):
@Pere-Lluis This error happens because you have started Playground but you haven't cleaned out your local storage and so whatever identity you have switched to it has remembered. Unfortunately when playground starts it attempts to check the fabric to see if it needs to deploy but to do that requires a different identity to the one it is currently trying with

Pere-Lluis (Tue, 04 Jul 2017 15:02:12 GMT):
@davidkel Okey, but it asks me for a identity before giving me that error

Pere-Lluis (Tue, 04 Jul 2017 15:03:17 GMT):
and gives me a different error whether I type an existing one or a non existing one so it is using the current identity

Pere-Lluis (Tue, 04 Jul 2017 15:03:27 GMT):
but it's alright, I'll move on for now

davidkel (Tue, 04 Jul 2017 15:06:33 GMT):
@Pere-Lluis You need to use the id that you used to deploy a business network, but if you are running playground in a docker container then you won't have that id imported into the container filesystem

Pere-Lluis (Tue, 04 Jul 2017 15:07:21 GMT):

hi everyone!

Pere-Lluis (Tue, 04 Jul 2017 15:07:40 GMT):
But that's the way of running it right?

Pere-Lluis (Tue, 04 Jul 2017 15:07:50 GMT):
anyway I have a more conceptual question, when you use the composer-rest-server, to which peer is it making the calls? Any in the connection profile?

Pere-Lluis (Tue, 04 Jul 2017 15:07:56 GMT):
hi there!

MohammedAhmed (Tue, 04 Jul 2017 15:08:24 GMT):

Pere-Lluis (Tue, 04 Jul 2017 15:09:13 GMT):
well, I'm sure you could, but that's a too generic question

Pere-Lluis (Tue, 04 Jul 2017 15:09:34 GMT):
maybe try in #fabric or #general ?

MohammedAhmed (Tue, 04 Jul 2017 15:09:55 GMT):
maybe it looks like a cryptocurrency I just want to manage users access and transactions thats all

Pere-Lluis (Tue, 04 Jul 2017 15:10:36 GMT):

can you help where I can find more info about licencing to uses fabric ?

Pere-Lluis (Tue, 04 Jul 2017 15:12:41 GMT):
oh, I have no idea about that, but since it's an open source project I'm sure you can use it

Pere-Lluis (Tue, 04 Jul 2017 15:13:14 GMT):
but then again I think you will find more answers in #general

Pere-Lluis (Tue, 04 Jul 2017 15:13:22 GMT):
about that

MohammedAhmed (Tue, 04 Jul 2017 15:13:39 GMT):
thanks pere :)

Pere-Lluis (Tue, 04 Jul 2017 15:13:45 GMT):
or #fabric, I'm not sure

davidkel (Tue, 04 Jul 2017 15:16:22 GMT):
@Pere-Lluis Requests are sent to all peers defined in the connection profile, that applies to all composer services including the rest server

gen_el (Tue, 04 Jul 2017 15:20:19 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=bX92injHzCKnM74AB) @davidkel I guess that should do. Thanks

Pere-Lluis (Tue, 04 Jul 2017 15:24:21 GMT):
@davidkel and the Key Value Store Directory is stored in the Docker file in Local Playground?

davidkel (Tue, 04 Jul 2017 15:26:02 GMT):
@Pere-Lluis Yes the KeyValStore directory will be in the Container filesystem

Pere-Lluis (Tue, 04 Jul 2017 15:26:31 GMT):
I think that was my problem, it didn't have the proper keys there

Pere-Lluis (Tue, 04 Jul 2017 15:26:37 GMT):
I'll check tomorrow, thanks!

Hihi~I would like to install the Composer development environment to build up my own website, and I'm using win10 64bit. But I checked the prerequisites, windows is not on the operating system list?

jellevdp (Tue, 04 Jul 2017 17:28:07 GMT):
Hi - is there a specific reason why composer-client can not add a connection profile to the profile store (only admin)?

dselman (Tue, 04 Jul 2017 21:30:03 GMT):
@JunLi_June looks like you are trying to run on Windows -- this is not a supported platform (check the docs).

JunLi_June (Tue, 04 Jul 2017 21:36:07 GMT):
@dselman yes, i already realised about that, and read the issue on Github~ In this situation, could you please give me some suggestions, if I do need to run on Windows, and I need to implement a website for with smart contract, which project or tool I can use? btw, this website is only for study purpose, not for any actual projects.

dselman (Tue, 04 Jul 2017 21:37:14 GMT):
Last time I checked Hyperledger Fabric itself doesn't run natively on Fabric, so the easiest thing to do is to install a Linux VM on your Windows machine and use that for development.

Hi guys

how to save a pdf file with Hyperledger Composer?

dselman (Tue, 04 Jul 2017 21:38:16 GMT):
Store the data off chain and store a URL to the PDF along with a checksum on the chain.

dselman (Tue, 04 Jul 2017 21:38:59 GMT):
E.g. store it in Cloudant, IPFS or similar.

dselman (Tue, 04 Jul 2017 21:39:24 GMT):
We would like to make this easier but don't have concrete plans around that yet.

@sstone1 ok

@JonathanTan there's a fix for `console.log` and Fabric v1.0 going in to 0.9.1 tomorrow. in the mean time you can use `print` instead of `console.log`

sstone1 (Wed, 05 Jul 2017 07:52:04 GMT):
@chenxuan yes that should work fine

sstone1 (Wed, 05 Jul 2017 07:52:47 GMT):
work is happening at the moment to add query files to playground, but not sure what you mean by playground not supporting 0.9.0? we did publish a new version of playground along with the rest of the code.

@KevinBai Composer does work with Fabric rc1, but currently installs the beta, however this weeks release 0.9.1 will move all of the scripts over to rc1

Pere-Lluis (Wed, 05 Jul 2017 08:12:56 GMT):
Hi there

Pere-Lluis (Wed, 05 Jul 2017 08:13:39 GMT):
I added my .hfc-key-store to the docker composer-playground

Pere-Lluis (Wed, 05 Jul 2017 08:14:05 GMT):
but I'm getting a Error: error trying login and get user Context. Error: EACCES: permission denied, open '/home/composer/.hfc-key-store/c00305b28997cd8b9da0a9683c3310974f92287541e5bd4ef847c0b6a40eb0dc-pub'

Pere-Lluis (Wed, 05 Jul 2017 08:15:20 GMT):
I tried to change the files permision in the container but it doens't let me

Pere-Lluis (Wed, 05 Jul 2017 08:29:36 GMT):
I changed the permissions before loading the docker and it worked, now it's connected to my peers, but instead of connecting to the existing chaincode, it has created a new one dev-peer0.org1.example.com-org-acme-biznet-0.9.0

Pere-Lluis (Wed, 05 Jul 2017 08:30:45 GMT):
so I wonder, it's possible to deploy more than one bna to the same channel (as I seem to have) and how do I set playground to work to an existing deployed chaincode in the channel, since the connection profiles will be the same

Pere-Lluis (Wed, 05 Jul 2017 08:31:44 GMT):
It is not like this is a practical real work example that would happen, I'm just curious about this stuff in order to understand how it works

sstone1 (Wed, 05 Jul 2017 08:33:51 GMT):
@Pere-Lluis are you mounting the credentials into the Docker container using volume mounts? the permissions you need for that got me stuck the other day

sstone1 (Wed, 05 Jul 2017 08:34:12 GMT):
playground can currently only work with a business network called `org-acme-biznet` - it will not connect to any other business networks with different names

sstone1 (Wed, 05 Jul 2017 08:34:26 GMT):
we are working on fixing this - that is part of the major rework being done around ID cards

Pere-Lluis (Wed, 05 Jul 2017 08:46:55 GMT):
You're right, you mentioned it on themeeting

Pere-Lluis (Wed, 05 Jul 2017 08:47:16 GMT):
yeah, I'm using a yml file where I set a

Pere-Lluis (Wed, 05 Jul 2017 08:47:35 GMT):
composer: container_name: composer image: hyperledger/composer-playground volumes: - /home/pere-lluis/.hfc-key-store:/home/composer/.hfc-key-store

Pere-Lluis (Wed, 05 Jul 2017 08:48:03 GMT):
I just changed to 777 tthe files on /home/pere-lluis/.hfc-key-store and it worked once added to the docker

Pere-Lluis (Wed, 05 Jul 2017 08:48:39 GMT):
Not an elegant solution, but worked for now, it is connected to the fabric using the right credentials

Pere-Lluis (Wed, 05 Jul 2017 08:51:51 GMT):
also I'm going forward since I have my bna pretty stable and working, what do you recommend if I want to use it in an existing website (which I would have to adapt) where users are login thought Google? I'm really new to all this API stuff, so I'm not sure which direction to follow. If I want each user of the website (that logs in with Google) to be one participant on the chain? Is suing the RestAPI with Google Oauth the way to interact with the website?

Pere-Lluis (Wed, 05 Jul 2017 08:52:10 GMT):
do you have any tips @sstone1 ?

smallX (Wed, 05 Jul 2017 08:53:48 GMT):
hi guys, how to get height of blockchain by composer?

sstone1 (Wed, 05 Jul 2017 09:00:12 GMT):
@Pere-Lluis yeah, using the REST server in combination with the Passport strategy for Google OAuth is the way to go. Each user who authenticates to the REST server using Passport gets their own wallet, where they can put Blockchain identities/certs that the REST server uses to communicate with the Blockchain. Composer maps Blockchain identities/certs to participants.

sstone1 (Wed, 05 Jul 2017 09:01:12 GMT):
@smallX there is no Composer API for that.

Pere-Lluis (Wed, 05 Jul 2017 09:05:12 GMT):
@sstone1 cool, thanks.

Pere-Lluis (Wed, 05 Jul 2017 09:05:32 GMT):
also, there is a problem with the pii-network in github I think

Pere-Lluis (Wed, 05 Jul 2017 09:05:41 GMT):
trying to deploy it gives a SyntaxError: The keyword 'extends' is reserved (4:0)

Pere-Lluis (Wed, 05 Jul 2017 09:06:04 GMT):
even in https://composer-playground.mybluemix.net

Pere-Lluis (Wed, 05 Jul 2017 09:07:05 GMT):
should I add an issue @sstone1 or are you already aware of it?

Pere-Lluis (Wed, 05 Jul 2017 09:09:18 GMT):
Also... why is there NEM stuff in the files of the pii-network?

arner (Wed, 05 Jul 2017 09:12:44 GMT):
@Pere-Lluis this is a known issue and will be solved in the next release of playground :) [so I heard from @dselman, I'm not part of the team]

Pere-Lluis (Wed, 05 Jul 2017 09:14:28 GMT):
@arner okey, just wanted to warn about it, I think someone stored stuff that doesn't belong there xD

sstone1 (Wed, 05 Jul 2017 09:18:29 GMT):
Yeah, Playground is incorrectly importing an `.eslintrc.yml` file as a JavaScript script file, which causes that error

sstone1 (Wed, 05 Jul 2017 09:19:05 GMT):
Playground 0.9.1 is dropping the import from GitHub, and adding in import from npm - no authentication needed to use the samples, and it also works off of the published and tested BNA files which avoid this problem.

smallX (Wed, 05 Jul 2017 09:19:06 GMT):
will we complete it about the API for height of blockchain in the future ?

sstone1 (Wed, 05 Jul 2017 09:20:35 GMT):
it's not in the plans at the moment - can you explain more about why you need it and what you would use the API for, and why the Fabric API is not sufficient?

Include the output of `docker ps -a` + 'node -v` + `docker -v` - and the output of `composer --version` please. From what I've seen its possible (in your environment) that the node modules are at mismatched levels... ie the backend Fabric vs your Composer levels. Have you uninstalled previous Composer versions first and then installed (preferably) the latest Composer (0.9.0) before running the Developer tutorial and to match your environment (assuming its at Fabric v1 beta) ? thanks!

ShobhanaSundararaman (Wed, 05 Jul 2017 11:34:49 GMT):

@davidkel are there any new APIs in v1.0 for revoking/deleting Fabric CA identities that we should look at utilising?

'Hello, I am writing a rest client using composer node sdk. In the very basic method i am creating a businessconnection object and trying connect., there after i am also disconnecting connection but somehow event listners are not getting removed. On the 11th call to the method i am getting warning Warning: Possible EventEmitter memory leak detected. 11 exit listeners added. Use emitter.setMaxListeners() to increase limit'

vinitesh (Wed, 05 Jul 2017 12:16:24 GMT):
following is the code snippet

vinitesh (Wed, 05 Jul 2017 12:16:25 GMT):
app.post('/loginTest', (req, res) => { var bizNetworkConnection = new BusinessNetworkConnection(); bizNetworkConnection.connect("hlfv1", "org.acme.biznet", "admin", "adminpw") .then(function (result) { console.log("connection success ") console.log("user " + bizNetworkConnection.securityContext.getUser()) bizNetworkConnection.disconnect().then(function () { console.log("user2 "+bizNetworkConnection.securityContext) bizNetworkConnection=null res.json({ status: "result" }); }) // }).catch(function (error) { console.log("111111" + error); bizNetworkConnection.disconnect().then(function () { res.send(error); }); }) })

uber.twin (Wed, 05 Jul 2017 12:16:43 GMT):
@sstone1 so then there is no such thing as a completely symmetrical operation of "issueIdentity"?

davidkel (Wed, 05 Jul 2017 12:16:59 GMT):
@sstone1 there is a revoke api and a reenroll api we could exploit

sstone1 (Wed, 05 Jul 2017 12:18:20 GMT):
@uber.twin correct, but only because we didn't have those APIs in v0.6 - @davidkel probably worth raising a yser story to investigate that at some point

mahoney1 (Wed, 05 Jul 2017 12:24:45 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=iBD4kWGXNzPBXNc97) @vinitesh in your sample have you tried setting listeners eg. require('events').EventEmitter.defaultMaxListeners = 15; for example?

vinitesh (Wed, 05 Jul 2017 12:28:50 GMT):
@mahoney1 thats not gonna help i think, Actual problem is even after disconnecting, event listners are not been removed

Hi, is it necessary to write test cases for generating .bna file and further deploying? I am trying to create a demo and test case is not necessary as of now.

Pere-Lluis (Wed, 05 Jul 2017 14:57:00 GMT):
test codes are not necessary, just a tool in order to set an automatic testing system

Pere-Lluis (Wed, 05 Jul 2017 14:58:20 GMT):
@coder-ajay for your .bna the only "needed" as of a basic .bna files are the permissions as a .acl, the .cto to define your "variables" in the chain and at least one .js in your lib for the transactions

coder-ajay (Wed, 05 Jul 2017 14:59:36 GMT):
ok. so is it fine if I keep the test/sample.js file empty?

coder-ajay (Wed, 05 Jul 2017 14:59:50 GMT):
just to avoid any possible error.

coder-ajay (Wed, 05 Jul 2017 15:01:29 GMT):
or can it be simply ignored?

Pere-Lluis (Wed, 05 Jul 2017 15:02:33 GMT):
you can even delete it

coder-ajay (Wed, 05 Jul 2017 15:04:09 GMT):
Ok. Thanks @Pere-Lluis

Pere-Lluis (Wed, 05 Jul 2017 15:26:29 GMT):
And another question about permissions, I have tried to put a permission making reference to the owner of the asset in the transaction, but I think that you can only refer to properties of the transaction itself, am I wrong?

Pere-Lluis (Wed, 05 Jul 2017 15:27:02 GMT):
Because I have:

Pere-Lluis (Wed, 05 Jul 2017 15:27:37 GMT):
rule closeApportionmentTransactions { description: "Allow all participants to submit transactions" participant(p): "org.basetis.bonusetis.user" operation: CREATE resource(a): "org.basetis.bonusetis.close" condition: (a.asset.owner.getIdentifier() === p.getIdentifier()) action: ALLOW }

Pere-Lluis (Wed, 05 Jul 2017 15:28:47 GMT):
and it gives me a can't read property getIdentifier of undefined

Pere-Lluis (Wed, 05 Jul 2017 15:29:23 GMT):
(the transaction close has a relationship with an asset)

Pere-Lluis (Wed, 05 Jul 2017 15:32:58 GMT):
So I think it's not a code problem but the fact that properties of variables of the transaction cannot be read in the acl or something like that, can anyone confirm?

how to set loglevel for composer-rest-server

dwakeman (Wed, 05 Jul 2017 15:55:37 GMT):

I haven't used it with composer-rest-server, but for composer-cli I have set an environment variable before I run the command: `export DEBUG=composer:*` Then, when you run composer-rest-server it should produce more verbose output.

transaction close { --> apportionment asset }

Pere-Lluis (Wed, 05 Jul 2017 15:57:48 GMT):
and the asset is:

Pere-Lluis (Wed, 05 Jul 2017 15:58:01 GMT):
asset apportionment identified by bonusIDuserID{ o String bonusIDuserID default= "bonusID:1userID:1" --> user owner o Integer percentatge default=100 range=[0,100] --> Bonus bonus o Integer close }

Pere-Lluis (Wed, 05 Jul 2017 15:59:10 GMT):
@mahoney1 so the idea is that only if the current participant is the owner of the apportionment, he would be able to do the transaction close

Pere-Lluis (Wed, 05 Jul 2017 15:59:30 GMT):
Right now I have done it by code in the .js

dwakeman (Wed, 05 Jul 2017 17:19:34 GMT):
There is a new command called `composer identity import` that is now part of composer, and I think it's supposed to import key files and create a wallet in my KeyValStore, right? If I am using the docker images from Hyperledger, where do I get the files containing the public and private keys? Or am I not understanding how this is supposed to work?

Sij (Wed, 05 Jul 2017 17:58:35 GMT):
Has joined the channel.

davidkel (Wed, 05 Jul 2017 18:59:02 GMT):
@dwakeman you are correct, that is the purpose of composer identity import in that it will create identities from existing crypto material. The hyperledger fabric images are nothing more than pre-canned binaries. To create a fabric you need MSP providers as well as a set of configuration definitions to configure your running fabric and the policies that govern it. If you download the composer fabric dev server this is a complete definition of a fabric albeit a simple one for development purposes. In there it has MSP definitions which are based on PKI. For example the crypto material that defines who has admin authority for a peer is contained in there and you would import that crypto material and give it an identity. You can then use that identity to be able to install chaincode on that peer.

davidkel (Thu, 06 Jul 2017 07:13:40 GMT):
@raheelz when you deployed your business network you used version 0.8.1 but now you have upgraded your cli and dependencies for your application to 0.9.0. Due to breaking api changes in 0.9.0 you would need to make changes to your business network and redeploy to get both your client side and deployed chaincode side to matching 0.9.0 levels. Alternatively you could downgrade your cli and application dependencies to 0.8.1 for now but probably better to do the former

gen_el (Thu, 06 Jul 2017 09:44:30 GMT):
So a participant 1 on *channel A* may have assets Q, R, T

gen_el (Thu, 06 Jul 2017 09:45:01 GMT):
another participant 2 on same *channel A* may have assets V, W

gen_el (Thu, 06 Jul 2017 09:45:43 GMT):
now on *channel B* _participant 1_ has assets G, H,

gen_el (Thu, 06 Jul 2017 09:47:14 GMT):
on same *channel B* participant 2 has assets I, J, K

dselman (Thu, 06 Jul 2017 09:50:00 GMT):
that I get, but why does the business network need to know its channel name

gen_el (Thu, 06 Jul 2017 09:50:44 GMT):
@dselman so when i run a query, on chain code on *channel A* to retrieve all assets, i will not see assets managed on channel B. Right?

each channel is its own ledger

coder-ajay (Thu, 06 Jul 2017 11:42:31 GMT):
e.g i changed asset name Commodity to Vehicle in all relevant files?

coder-ajay (Thu, 06 Jul 2017 11:44:18 GMT):
do I have to run code for .bna file again and upload it on playground?

ulysses (Thu, 06 Jul 2017 12:39:50 GMT):

ulysses (Thu, 06 Jul 2017 12:44:25 GMT):
@coder-ajay Yep. executed both startFabric and createComposerProfile scripts

sstone1 (Thu, 06 Jul 2017 12:44:46 GMT):
@ulysses can you run `composer -v` and paste the input in here

sstone1 (Thu, 06 Jul 2017 12:44:46 GMT):

sstone1 (Thu, 06 Jul 2017 12:48:38 GMT):
you need to re-run the Yeoman generator to generate new Angular components

coder-ajay (Thu, 06 Jul 2017 12:49:33 GMT):
i think i did ... let me try again

davidkel (Thu, 06 Jul 2017 12:50:15 GMT):
@ulysses The second instance failure message is because you are using the wrong identity to try to deploy. Try again with -i PeerAdmin (so long as you are using the fabric downloaded as documented through our guides)

ulysses (Thu, 06 Jul 2017 12:55:48 GMT):
@davidkel thanks. Second instance passed. Still getting the same error on the first instance, though.

davidkel (Thu, 06 Jul 2017 12:57:35 GMT):
@ulysses could you uninstall and re-install composer-cli by running `npm uninstall -g composer-cli && npm install -g composer-cli`. I have never seen that error before and connect see what would generate that error

ulysses (Thu, 06 Jul 2017 13:09:01 GMT):
@davidkel reinstalling the cli did not work. Meanwhile, on the second instance, I'm getting connection failure from the composer-rest-server ? Enter your Fabric Connection Profile Name: hlfv1 ?

coder-ajay (Thu, 06 Jul 2017 13:09:10 GMT):
@sstone1 re-running Yeoman generator is not working ... basically localhost:3000/explorer does not show any change ... all the tabs and keys in post section are same as for my-network.. am i missing any step?

davidkel (Thu, 06 Jul 2017 13:12:08 GMT):
@ulysses definitely uninstall the composer-rest-server and re-install it, that looks like a message from a very old version of composer. Also for the rest server, you should use admin/adminpw not PeerAdmin. PeerAdmin although it would work in the beginning, it isn't the right id to be using you will want to use an id that comes from the CA Server.

davidkel (Thu, 06 Jul 2017 13:13:12 GMT):
@ulysses No idea of the problem with your first instance, can only assume that you might have old versions of composer lying around interferring somehow

sstone1 (Thu, 06 Jul 2017 13:13:46 GMT):
@here we've released Hyperledger Composer v0.9.1, with some awesome new features, read all about it on GitHub: https://github.com/hyperledger/composer/releases/tag/v0.9.1 🎉

sstone1 (Thu, 06 Jul 2017 13:14:05 GMT):
@coder-ajay oh, sorry, http://localhost:3000/explorer is the REST API server

sstone1 (Thu, 06 Jul 2017 13:14:23 GMT):
is the REST server running when you run `npm start`, or are you running it separately?

sstone1 (Thu, 06 Jul 2017 13:14:29 GMT):
I mean the `composer-rest-server`

coder-ajay (Thu, 06 Jul 2017 13:15:17 GMT):
i run composer-rest-server first ... localhost:3000/explorer didnt show any change.

coder-ajay (Thu, 06 Jul 2017 13:15:22 GMT):
after that I run npm start

ulysses (Thu, 06 Jul 2017 13:15:49 GMT):
@davidkel the first instance is running on a newly provisioned machine with a fresh install.

coder-ajay (Thu, 06 Jul 2017 13:16:30 GMT):
i did required changes in .cto and lib>sample.js file

coder-ajay (Thu, 06 Jul 2017 13:19:18 GMT):
@sstone1 : how to change the value in explorer > commodity > commodity create > post > parameters > example value? its showing old my-network values. Can i simply add new values in the 'value' text box?

sstone1 (Thu, 06 Jul 2017 13:20:38 GMT):
by old values do you mean the old structure of the class?

coder-ajay (Thu, 06 Jul 2017 13:21:17 GMT):
yes .. currently its showing "$class": "org.acme.cpa.Commodity", "tradingSymbol": "string", "description": "string", "mainExchange": "string", "quantity": 0, "owner": "string" i dont need tradingSymbol or mainExchange in my demo

sstone1 (Thu, 06 Jul 2017 13:21:30 GMT):
how did you deploy the updated BNA file to the Blockchain? where did you run `composer network deploy` or `composer network update` ?

mahoney1 (Thu, 06 Jul 2017 13:24:55 GMT):
@here - reminder that our Community call later today is at 4pm UTC (5pm UK, 12pm ET, 9am PT) - would love to hear about the things you are building with Composer, what you like/don't like ;come talk to us (and other community members) in person !! Meeting details and agenda items are here: https://github.com/hyperledger/composer/wiki/Meeting-6th-July-2017 cheers Paul

coder-ajay (Thu, 06 Jul 2017 13:28:42 GMT):
@sstone1 : i run the 'composer network deploy' in dist folder where .bna file is present

sstone1 (Thu, 06 Jul 2017 13:29:29 GMT):
did you rebuild the .bna file using `composer archive create` ?

VamsiKrishnak (Thu, 06 Jul 2017 13:29:50 GMT):
@sstone1 I am using http://hyperledger-fabric-doc.readthedocs.io/en/latest/getting_started.html for Hyperledger Fabric setup in Ubuntu VM. Asper tutorial two organisation with two peers have been created. I wanted to add new organization or new peer in already existing Organisation dynamically. Kindly help me know the steps to add dynamically

sstone1 (Thu, 06 Jul 2017 13:30:12 GMT):
@VamsiKrishnak that is a Fabric question, you need to ask it in the #fabric channel

VamsiKrishnak (Thu, 06 Jul 2017 13:30:34 GMT):
ok sure, thank you

coder-ajay (Thu, 06 Jul 2017 13:33:15 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=755fzJKh2BFD4eJn2) @sstone1 : i think i missed this step. Do i have to run this command in the project folder? is this the syntax 'composer archive create' ?

ulysses (Thu, 06 Jul 2017 13:33:19 GMT):
@davidkel reinstall of composer-rest-server still ends up showing the same error: ? Enter your Fabric Connection Profile Name: hlfv1 ? Enter your Business Network Identifier : my-network ? Enter your Fabric username : admin ? Enter your secret: adminpw ? Specify if you want namespaces in the generated REST API: never use namespaces Discovering types from business network definition ...

sstone1 (Thu, 06 Jul 2017 13:34:08 GMT):
@coder-ajay are you following this tutorial

sstone1 (Thu, 06 Jul 2017 13:34:09 GMT):
https://hyperledger.github.io/composer/tutorials/developer-guide.html

sstone1 (Thu, 06 Jul 2017 13:34:19 GMT):
see the steps under "Generate the Business Network Archive"

sstone1 (Thu, 06 Jul 2017 13:34:31 GMT):
namely `npm install` or `npm run prepublish` in the business network directory

sstone1 (Thu, 06 Jul 2017 13:34:39 GMT):
that packages the model files, script files, etc into the BNA file

baoyangc (Thu, 06 Jul 2017 13:35:20 GMT):
`Connection fails: Error: The events array has not been specified in the connection profile It will be retried for the next request.`

baoyangc (Thu, 06 Jul 2017 13:35:48 GMT):
@ulysses

coder-ajay (Thu, 06 Jul 2017 13:35:55 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=d4TWsFLxbsGK4chGb) @sstone1 : i run 'npm install' ... to make sure that the .bna file is correctly created, I uploaded it on the playground and cross verified the changes on playground.

ulysses (Thu, 06 Jul 2017 13:39:48 GMT):
@baoyangc should there be an events array in the connection profile? I'm using the defaults here.

baoyangc (Thu, 06 Jul 2017 13:41:31 GMT):
use the default? the defaults should be ok

sstone1 (Thu, 06 Jul 2017 13:42:47 GMT):
@coder-ajay OK, so what is the output from the `composer network deploy` command? can you paste in the command you used and the output from the command?

ulysses (Thu, 06 Jul 2017 13:44:14 GMT):
@baoyangc the default doesnt have any events arry specs.

baoyangc (Thu, 06 Jul 2017 13:45:00 GMT):
```{ "type": "hlfv1", "orderers": [ { "url": "grpc://localhost:7050" } ], "ca": { "url": "http://localhost:7054", "name": "ca.example.com" }, "peers": [ { "requestURL": "grpc://localhost:7051", "eventURL": "grpc://localhost:7053" } ], "keyValStore": "/Users/baoyangc/.hfc-key-store", "channel": "mychannel", "mspID": "Org1MSP", "timeout": "300" }```

baoyangc (Thu, 06 Jul 2017 13:45:13 GMT):
this is my connection.json

coder-ajay (Thu, 06 Jul 2017 13:46:05 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=5rhb4noyTsz7FjHbP) @sstone1 composer network deploy -a cpa.bna -p hlfv1 -i PeerAdmin -s randomString Deploying business network from archive: cpa.bna Business network definition: Identifier: cpa@0.0.1 Description: CPA application ✔ Deploying business network definition. This may take a minute... Command succeeded

ulysses (Thu, 06 Jul 2017 13:52:00 GMT):
@baoyangc thats how my connection.json looks as well

davidkel (Thu, 06 Jul 2017 14:01:09 GMT):
@ulysses you have the right connection profile, it's the level of composer code that is very old. Don't know how you are in that situation but that error definitely comes from old composer code which doesn't exist anymore

sstone1 (Thu, 06 Jul 2017 14:01:33 GMT):
@coder-ajay have you got the command line for the Composer REST server?

ulysses (Thu, 06 Jul 2017 14:04:05 GMT):
@davidkel I did an npm uninstall and install but am still stuck with the same error. Meanwhile, the first instance is still stuck on bna deployment

mahoney1 (Thu, 06 Jul 2017 14:04:18 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=gMhhomdBLcujg3NBC) @coder-ajay so you successfully deployed the new network via npm install ; I assume you then ran composer-rest-server ; completed the dialog prompts - and the next thing to try is to clear your browser cache and reload the REST API Explorer

coder-ajay (Thu, 06 Jul 2017 14:05:16 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=3R9nkbnYGfn8WobPQ) @mahoney1 : ok let me try clearing browser cashe

Pere-Lluis (Thu, 06 Jul 2017 14:06:48 GMT):
@sstone1 maybe you can answer this, it possible to get an automatic transaction depending on a variable? I have a "closing date" for a contract, and I would like to change an asset if the date is reached.

sstone1 (Thu, 06 Jul 2017 14:10:16 GMT):
@Pere-Lluis there is no cron/scheduler/timer in Fabric v1.0 for us to implement that functionality

sstone1 (Thu, 06 Jul 2017 14:10:32 GMT):
You would need to set up the timer externally and get that external process to submit a transaction

uber.twin (Thu, 06 Jul 2017 14:10:41 GMT):
@sstone1 Hi, the Fabric setup guide states that "By default, we are using a consensus plugin called NOOPS, which doesn’t really do consensus" I presume this holds true for the environment deployed through the "composer-tools" repo, right?

davidkel (Thu, 06 Jul 2017 14:10:51 GMT):
@ulysses for your composer rest server, I can see from the error shown above that it is definitely using old code. I see you are using nvm, so can you `npm uninstall -g composer-rest-server` and check that in the directory `/home/ulysses/.nvm/versions/node/v6.9.5/lib/node_modules/` that there is no directory composer-rest-server anymore. Then check by typing composer-rest-server to show that the command cannot be executed. Once done, could you install composer-rest-server again using `npm install -g composer-rest-server` and try again

coder-ajay (Thu, 06 Jul 2017 14:11:43 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=3R9nkbnYGfn8WobPQ) @mahoney1 : Cache clear is not working ... on the playground, assets are getting created, but submit transaction is not working because of something I have missed. Can that be the reason of explorer not getting refreshed with new keys?

sstone1 (Thu, 06 Jul 2017 14:12:06 GMT):
@uber.twin correct, the fabric-dev-server configuration that we provide is a 1x peer 1x orderer 1x CA configuration that uses the noops plugin for consensus.

Pere-Lluis (Thu, 06 Jul 2017 14:12:08 GMT):
@sstone1 okey, what I thought, kind of the temperature example in the perishable network

Pere-Lluis (Thu, 06 Jul 2017 14:12:13 GMT):
thank you

sstone1 (Thu, 06 Jul 2017 14:12:26 GMT):
np

Pere-Lluis (Thu, 06 Jul 2017 14:13:36 GMT):
@sstone1 and before I try it... can u start a transaction within a transaction?

sstone1 (Thu, 06 Jul 2017 14:14:23 GMT):
you can call another transaction processor function from a transaction processor function

sstone1 (Thu, 06 Jul 2017 14:14:27 GMT):
e.g. one JS function calling another

sstone1 (Thu, 06 Jul 2017 14:14:35 GMT):
but no new transaction record is created for it

sstone1 (Thu, 06 Jul 2017 14:14:52 GMT):
we'd like to have the ability to trigger transactions from events that are emitted by a transaction processor function

sstone1 (Thu, 06 Jul 2017 14:15:07 GMT):
for a more decoupled approach

Pere-Lluis (Thu, 06 Jul 2017 14:18:37 GMT):
cool, it's okey for now, just wondering

uber.twin (Thu, 06 Jul 2017 14:19:20 GMT):
@sstone1But are there any plans to have an end to end guide for building a production ready, commercial grade Fabric/ Composer platform? With all security features enabled and a real consensus in place?

uber.twin (Thu, 06 Jul 2017 14:19:20 GMT):
@sstone1 But are there any plans to have an end to end guide for building a production ready, commercial grade Fabric/ Composer platform? With all security features enabled and a real consensus in place?

Pere-Lluis (Thu, 06 Jul 2017 14:19:27 GMT):
by the way is there a backlog?

sstone1 (Thu, 06 Jul 2017 14:20:18 GMT):
@Pere-Lluis all our work is tracked as GitHub issues: https://github.com/hyperledger/composer/issues

sstone1 (Thu, 06 Jul 2017 14:20:53 GMT):
we have a master issue that records everything for a "v1.0" (though it is unlikely to be called v1.0)

sstone1 (Thu, 06 Jul 2017 14:20:55 GMT):
https://github.com/hyperledger/composer/issues/1390

Pere-Lluis (Thu, 06 Jul 2017 14:21:33 GMT):
@sstone1 Thank you, I'll take a look

sstone1 (Thu, 06 Jul 2017 14:22:23 GMT):
@uber.twin a lot of that guide would be the Fabric documentation describing how to set up a proper production network. once they have that kind of documentation then we can explain how to deploy Composer to that Fabric, and how to deploy additional components like the REST server.

ulysses (Thu, 06 Jul 2017 14:24:28 GMT):
@davidkel that worked! Still not sure about the first instance.

davidkel (Thu, 06 Jul 2017 14:28:26 GMT):
@ulysses The error comes from grpc by the looks of things. Can you describe your 1st instance setup. Operating System, Memory, Disk space, Virtual or Real ?

davidkel (Thu, 06 Jul 2017 14:28:44 GMT):
Also check your level of node and npm on that machine as well

Pere-Lluis (Thu, 06 Jul 2017 14:35:40 GMT):
@sstone1 That's the feeling I get trying to think of a real world implementation, that Fabric still lacks a more user-friendly approach to provide documentation in order to create one. I guess it's understandable as it is in development, in that sense I feel more comfortable working with composer.

sstone1 (Thu, 06 Jul 2017 14:37:26 GMT):
Agreed. There is a team now focusing on at least the documentation improved for Fabric - you can see that work being discussed in #fabric-documentation and I think they have regular calls, if you wanted to get involved.

sstone1 (Thu, 06 Jul 2017 14:37:26 GMT):

Pere-Lluis (Thu, 06 Jul 2017 14:38:46 GMT):
oh, cool, maybe I will once I get more comfortable with it

sstone1 (Thu, 06 Jul 2017 14:39:01 GMT):
As an example, this is one of the new pages that they've built: https://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html

sstone1 (Thu, 06 Jul 2017 14:39:09 GMT):
And it's infinitely better than what was there before ;)

Pere-Lluis (Thu, 06 Jul 2017 14:39:22 GMT):
I will work full time from now, so I will get more time to try to help to

Pere-Lluis (Thu, 06 Jul 2017 14:40:12 GMT):
yeah, I saw that example and thought the same

Pere-Lluis (Thu, 06 Jul 2017 14:40:54 GMT):
I don't want to seem like complaining, I totally understand there's to much work at the time to think about documentation

Pere-Lluis (Thu, 06 Jul 2017 14:41:25 GMT):
but it's a classic for developers, it happens to me to, to forget documentation

ulysses (Thu, 06 Jul 2017 14:45:05 GMT):
@davidkel It's ubuntu 16.04, (1 vCPU, 3.75 GB memory), 20 gb disk, VM hosted on cloud

ulysses (Thu, 06 Jul 2017 14:46:19 GMT):
on a similar vm, I'm running a nodejs app using hlfv1-rc

dwakeman (Thu, 06 Jul 2017 14:49:32 GMT):
is the fabric-tools.zip file corrupt in the 0.9.1 release? I keep trying to download it using this command: ```curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.zip``` but I can't unzip the file that it downloads.

sstone1 (Thu, 06 Jul 2017 14:50:44 GMT):
works for me @dwakeman

sstone1 (Thu, 06 Jul 2017 14:50:58 GMT):
can you edit it in a text editor and see if it contains an HTTP error or something daft?

dwakeman (Thu, 06 Jul 2017 14:51:06 GMT):
hmmm... okay. I must be having a moron moment.

davidkel (Thu, 06 Jul 2017 14:53:56 GMT):
@ulysses 3.75Gb is below the minimum we recommend. Also what level of node and npm on that machine ?

dwakeman (Thu, 06 Jul 2017 14:55:30 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=ySaYa7WfCKwnaeH5N) @sstone1 must have been something wrong with the transfer. I did it several times and got the same result, but this time the file is bigger, and it extracted properly. Thanks for checking it!

ulysses (Thu, 06 Jul 2017 14:56:09 GMT):
node v6.11.0 npm 4.1.0

ulysses (Thu, 06 Jul 2017 14:56:09 GMT):
@davidkel node v6.11.0 npm v4.1.0

davidkel (Thu, 06 Jul 2017 15:01:11 GMT):
@ulysses I have no idea what the issue is, it's a grpc error and composer doesn't use grpc directly it uses the fabric-node-sdk which uses grpc. If you have tried clearing everything out and starting again and still have the problem then all I can think of is that 3.75Gb really isn't enough. I assume it is a 64bit instance of Ubuntu and not 32bit (If that even still exists for 16.04).

ulysses (Thu, 06 Jul 2017 15:03:47 GMT):
@davidkel it's a 64 bit instance. I'll try reprovisioning a VM with more RAM and see if it works

@sstone1 @mahoney1 : any other clue on why the explorer is not refreshing after changes in the asset, participant and transaction structure? After uploading on playground, the submit transaction is throwing error which I need to look into. Can this be the reason for explorer not getting updated?

I couldn't join the meeting but I have question regarding the ACL. Is it possible to allow participants only to issue transactions, but then allow those transactions to create or modify assets belonging to that participant or others?

Pere-Lluis (Thu, 06 Jul 2017 17:31:45 GMT):
okey, nervermind, found it in the documentation

[ ](https://chat.hyperledger.org/channel/composer?msg=ssMwC5WM2JGubdXu6) @coder-ajay I think I may have a clue - the prepublish earlier is premised on doing a mkdir && but the dir already exists (so theory is the .bna is unchanged because the archive isn't recreated). So try this: (ie your local environment). 1. run the command (ie from your project folder) `composer archive create --sourceType dir --sourceName . -a ./dist/my-network.bna` from your project folder and 2. (from the 'dist' subdir) run the command `composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s adminpw` 3. stop and restart your REST server `composer-rest-server` then finally 4. Go to your browser and 4. http://localhost:3000/explorer - should be good to go. Replace the 'BNA' filename with your own above if not the same etc etc.

gauthampamu (Thu, 06 Jul 2017 20:25:00 GMT):
@sstone1 Do you have a working sample of Composer that uses Fabric with Kafka and Zookeepers. Fabric sample just uses fabric with solo orderer which is not really how you would use in production/pilot environment. So I wanted to try composer with kafka network configuration.

sstone1 (Thu, 06 Jul 2017 20:25:52 GMT):
@gauthampamu no, we don't - there's nothing in Composer that cares what ordering service you use, so if you set up a Fabric with Kafka then Composer will deploy to it just fine.

gauthampamu (Thu, 06 Jul 2017 20:31:14 GMT):
If there are five organizations in the network and each organization has one peer or two peers. If you are building the application for organization A so when you are defining the connection profile, do you have to provide the hostnames of all the peers in the network, or is it sufficient to just provide the peer of your organization.

sstone1 (Thu, 06 Jul 2017 20:53:25 GMT):
when you are submitting Fabric v1.0 transactions, you must submit the transaction to all peers in the network that need to endorse that transaction

sstone1 (Thu, 06 Jul 2017 20:53:37 GMT):
so your Composer connection profile needs to have all peers required to meet the endorsement policy

`VALID_ENDORSEMENT_POLICY_STRING = '{"identities":[{ "role": { "name": "member", "mspId": "Org1MSP" }}], "policy": {"1-of": [{"signed-by":0}]}}';` i see this in the source code. so in cli, if i want to config policy, the command should like "composer network deploy -o '{"identities":[{ "role": { "name": "member", "mspId": "Org1MSP" }}], "policy": {"1-of": [{"signed-by":0}]}}'

Hi. I am using the trade-network from composer-sample-networks, and I have altered the trading.cto file with my own class names (Commodity, Trader, Trade etc.) but I have not changed the namespace. I also changed the functions in lib/logic.js to a function that previously have worked for me when I used composer 0.8.1. The namespace reference for the function in the logic.js file has been set to reffer to my own Trade class in the .cto. When I try to create the .bna file with npm install I get this error message: TypeNotFoundException: Type Commodity is not defined in namespace org.acme.trading at ModelManager.getType (/home/bcadmin/trade-network/node_modules/composer-common/lib/modelmanager.js:380:19) at Select.validate (/home/bcadmin/trade-network/node_modules/composer-common/lib/query/select.js:124:45) at Query.validate (/home/bcadmin/trade-network/node_modules/composer-common/lib/query/query.js:119:21) at queries.forEach (/home/bcadmin/trade-network/node_modules/composer-common/lib/query/queryfile.js:102:19) at Array.forEach (native) at QueryFile.validate (/home/bcadmin/trade-network/node_modules/composer-common/lib/query/queryfile.js:101:22) at QueryManager.setQueryFile (/home/bcadmin/trade-network/node_modules/composer-common/lib/querymanager.js:70:19) at Function.fromDirectory (/home/bcadmin/trade-network/node_modules/composer-common/lib/businessnetworkdefinition.js:543:51) at Function.handler (/home/bcadmin/trade-network/node_modules/composer-cli/lib/cmds/archive/lib/create.js:80:42) at Object.module.exports.handler (/home/bcadmin/trade-network/node_modules/composer-cli/lib/cmds/archive/createCommand.js:31:30) What am I missing here?

RudiDahle (Fri, 07 Jul 2017 08:00:56 GMT):
Side note. I just tried to change my asset name back to Commodity. Now "npm install" runs without any errors. Why can't I rename Commodity to something else?

sstone1 (Fri, 07 Jul 2017 08:02:04 GMT):
looks like Commodity is referenced somewhere else

sstone1 (Fri, 07 Jul 2017 08:02:12 GMT):
in a `queries.qry` file judging by the error

RudiDahle (Fri, 07 Jul 2017 08:04:04 GMT):
I was thinking it might be something like that. But I hav epreviously done the same thing in the my-network tutorial (this was in composer 0.8.1), and I could rename Commodity to whatever as long as I referenced to the new name in my .js functions

RudiDahle (Fri, 07 Jul 2017 08:04:30 GMT):
Which worked fine

Pere-Lluis (Fri, 07 Jul 2017 08:26:50 GMT):

@chenxuan the command is unable to communicate with your locally running fabric. Have you started it ? Also for network deploy you cannot use the 'admin' id to deploy. If you are using the fabric dev server we provide then you must use the id 'PeerAdmin' to deploy. There is no secret for it but you do need to provide a secret for now

[ ](https://chat.hyperledger.org/channel/composer?msg=49gNr7pehHM3HeY5P) @elrond aside from the resolution of --> Banka banka (which may be elsewhere defined in your model file) it looks good. If you don't have a local playground installed, you can if you wish, validate your model in http://composer-playground.mybluemix.net/editor - it will highlight any exceptions (assuming you've not validated it already). One thing to note: the error above says 'failed to find namespace net.croz ' - in your model file the namespace is defined as namespace net.croz.blockchain - can you check the js files if you're using a shortened reference, @param maybe?

[ ](https://chat.hyperledger.org/channel/composer?msg=8WMcrLqpcYYdREeL9) @levinkwong is this the first time you installed or you had a previous install? it would seem like v0.9.1 was there previously, so only CLI was 'downgraded' to v0.9.0. You should do `npm uninstall -g composer-cli` - then verify with `composer -v` that it is removed. Then perform the `npm install -g composer-cli@0.9.0` if you wish to install that version - then once again composer -v and see that the versions are as they should be.

Velibor (Fri, 07 Jul 2017 10:38:59 GMT):
Hi to all, does anyone know how to update composer, my current -v is 0.8.1?

[ ](https://chat.hyperledger.org/channel/composer?msg=qCiTMQ9utLhC2RukW) @Velibor hi, yes you need to unininstall with `npm uninstall -g composer-cli` and then perform `npm install -g composer-cli` and this will get you the latest Composer version (v0.9.1). (Also, if you have composer-rest-server or generator-hyperledger-composer installed backlevel you would have to uninstall and install to latest)

[ ](https://chat.hyperledger.org/channel/composer?msg=8WMcrLqpcYYdREeL9) @levinkwong it turns out that there is a Github issue relating to version inconsistency when installing earlier composer versions https://github.com/hyperledger/composer/issues/651 (item 2) - so doing `npm install -g composer-cli@0.9.0` will still give you the same version mix (as you had posted before). Until that Github issue is resolved, the alternative solution is to get the docker image eg. `docker pull hyperledger/composer-cli:0.9.0` and `docker run hyperledger/composer:0.9.0` and do your development inside the docker image

[ ](https://chat.hyperledger.org/channel/composer?msg=8WMcrLqpcYYdREeL9) @levinkwong it turns out that there is a Github issue relating to version inconsistency when installing earlier composer versions https://github.com/hyperledger/composer/issues/651 (item 2) - so doing `npm install -g composer-cli@0.9.0` will still give you the same version mix (as you had posted before). Until that Github issue is resolved, the alternative solution is to get the docker image eg. `docker pull hyperledger/composer-cli:0.9.0` and `docker run hyperledger/composer-cli:0.9.0` and do your development inside the docker image

@Pere-Lluis look in the docker-compose.yml file (in the hlfv1 directory) of the fabric dev server. In the environment section add `- CORE_CHAINCODE_EXECUTETIMEOUT=90s` to set the fabric execution timeout to 90 secs. eg ``` peer0.org1.example.com: container_name: peer0.org1.example.com image: hyperledger/fabric-peer:x86_64-1.0.0-rc1 environment: - CORE_LOGGING_PEER=debug - CORE_CHAINCODE_LOGGING_LEVEL=DEBUG

mahoney1 (Fri, 07 Jul 2017 12:49:47 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=2cDXPHLPL6PNmY9EP) @coder-ajay it is definitely better to use `composer archive create` as in `composer archive create --sourceType dir --sourceName . -a ./dist/my-network.bna` - as its a composer task. The npm install (in the tutorial at least) will do the archive create the first time you install the app. Beyond that, its good to get in the habit of running the composer command line to archive, deploy etc.

@mahoney1 I'm getting an error on Playground using a transaction that used to work

Pere-Lluis (Fri, 07 Jul 2017 15:50:31 GMT):
`ReferenceError: asset is not defined`

Pere-Lluis (Fri, 07 Jul 2017 15:51:09 GMT):
but there's no variable named asset in the transaction code

davidkel (Fri, 07 Jul 2017 15:51:35 GMT):
@Pere-Lluis if you don't mind sharing the .bna file then that would be useful too. Many thanks for doing that

Pere-Lluis (Fri, 07 Jul 2017 15:53:57 GMT):
I tried to debug and the transaction is working properly, the error was:

@davidkel okey, I'll add it now

@davidkel done

Pere-Lluis (Fri, 07 Jul 2017 15:58:06 GMT):
@mahoney1 it's working now... I don't know what was going wrong

Pere-Lluis (Fri, 07 Jul 2017 15:58:27 GMT):
I just deployed the bna again

Pere-Lluis (Fri, 07 Jul 2017 15:58:30 GMT):
anyway, thanks

davidkel (Fri, 07 Jul 2017 16:19:53 GMT):
@JennFoley Looks like you clicked "Add a file" to try to import a .bna file, you need to click import/replace instead

geoms (Fri, 07 Jul 2017 16:25:04 GMT):
I want have multiple nodes(peers) in composer environment . Is is possible to add an additional peer in hyperledger fabric through composer?

geoms (Fri, 07 Jul 2017 16:26:27 GMT):
I see in docker-compose.yml file there is a default peer peer0.org1.example.com

geoms (Fri, 07 Jul 2017 16:27:45 GMT):
When i tried to add another peer here. But not succeeded.

geoms (Fri, 07 Jul 2017 16:28:03 GMT):
Not sure, this is the right method to add another peer.

geoms (Fri, 07 Jul 2017 16:28:38 GMT):
I explored, Connection Profiles(https://hyperledger.github.io/composer/reference/connectionprofile.html).

geoms (Fri, 07 Jul 2017 16:29:55 GMT):
It seems, this will help to connect to a runtime, which already up and running. Means its doesn't add a new node(peer)

geoms (Fri, 07 Jul 2017 16:30:22 GMT):
Please help me on this

JennFoley (Fri, 07 Jul 2017 16:55:43 GMT):
@davidkel I didn't (tried a few times), but I figured out some things might have been cached and was able to modify my code in an old version of Composer Playground to remove TransactionID and be able to import to the new version. Any chance when you add code to the Playground that it doesn't deploy but lets one upload first to then make changes before deployment?

Hi, i would like to know when I am defining the ACL in a composer app

DannyWong (Fri, 07 Jul 2017 17:01:49 GMT):
which layer will the ACL translated into?

DannyWong (Fri, 07 Jul 2017 17:01:58 GMT):
the express middleware?

DannyWong (Fri, 07 Jul 2017 17:02:31 GMT):
or at chaincode level before calling the JavaScript tx processor script?

mahoney1 (Fri, 07 Jul 2017 17:28:53 GMT):

geoms (Fri, 07 Jul 2017 17:38:15 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=tWbQALnMZQa9ZuSDz) @mahoney1 Thanks. That means, the environment provides by 'Fabric composer' is for single organisation and one peer in the organisation ?

[ ](https://chat.hyperledger.org/channel/composer?msg=R9RGK37qk39xXdu52) @DannyWong The ACL rules protect access to data stored in the world state The ACL rules on assets and participants are implemented in Composer. Composer's Access Control Engine prevents transaction processor functions written in Javascript from accessing the data in the ledger, based on the type of access requested, the current participant, and the transaction being processed

[ ](https://chat.hyperledger.org/channel/composer?msg=eXCxcNrLqrdvJXLDw) @Dpkkmr can you raise this exact issue on Stack overflow please - and include the JSON for the transactions and responses as you had done here earlier, basically anything that helps with diagnosing the issue you see with a 2nd POST through the REST APIs exposed for that business network. By the way, and perhaps unrelated, we don't advocate that composer is installed using npm as root as it can cause issues - rather its install as a non-root user., I just noted this on the screenshot above. Thank you..

davidkel (Fri, 07 Jul 2017 18:50:00 GMT):
@geoms Not at all. Hyperledger composer will work with a variety of different topologies of hyperledger fabric. It's goal is not to provide any operational hyperledger fabric capabilities but work with a predefined hyperledger fabric topology. We provide a simple hyperledger fabric environment for development purposes only to assist in getting people started with hyperledger composer and hyperledger fabric.

@davidkel Hi! How do i get the return value of a submitTransaction() call?

CT123 (Fri, 07 Jul 2017 21:51:25 GMT):
Quick Q on running local version of composer: the docs on how to install and start are fine -- but I would like to simply restart the current version of HL composer I have locally. With docker already running is there a simple command to just restart composer? Running on a mac if that helps. Thanks in advance.

CT123 (Fri, 07 Jul 2017 22:54:24 GMT):
May have answered my own question -- composer.sh in the local install dir seems to do the trick

DannyWong (Sat, 08 Jul 2017 03:14:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=ntsxzTs5qJW7PrnzA) @mahoney1 Concept level I totally understood. I want to know more that 1) the ACL logic is translated into the NodeJS Express (the app that generated by composer); or into some go chaincode; or into some JavaScript and execute in the Duktape JavaScript VM that spin up by the Composer.go executor 2) The ACL rules (after translated) where are they stored? in some state? or directly translate as code We need to know more... as the ACL if just translated to middleware level... it means that someone can build another middleware with pure Fabric SDK then retrieve everything.

DannyWong (Sat, 08 Jul 2017 03:41:14 GMT):
Guys, just read the Composer v1 Grand Plan. The remaining stories are very exciting https://github.com/hyperledger/composer/issues/1390

davidkel (Sat, 08 Jul 2017 07:57:23 GMT):
@gen_el you can't get a return value from a submitted transaction and it wouldn't make sense to do so. You can however emit events from transaction processors see https://hyperledger.github.io/composer/business-network/publishing-events.html

dselman (Sat, 08 Jul 2017 11:56:45 GMT):
@DannyWong the ACL rules are interpreted by the Composer system chaincode ("middleware"). Conceptually this is no different to writing procedural Go code that does access control. I.e. if someone has physical access to the peer node, or can modify/redeploy the chaincode/business network definition, then all privacy protections are void.

dselman (Sat, 08 Jul 2017 18:25:28 GMT):

dselman (Sun, 09 Jul 2017 09:56:40 GMT):
Not sure. Perhaps you had deployed the network with an earlier version of composer-cli? Or you had a typo in the name of the network? Or the docker image for the network was stopped / crashed?

coder-ajay (Sun, 09 Jul 2017 09:58:10 GMT):
i believe the last option .. which of the above commands helped to restart it?

dselman (Sun, 09 Jul 2017 09:58:38 GMT):
the `composer network deploy` would spin up a new chaincode container

dselman (Sun, 09 Jul 2017 09:58:58 GMT):
if you see it again, run a `docker ps -a` and check the status of the containers

coder-ajay (Sun, 09 Jul 2017 10:00:38 GMT):
they are showing 'up with some minutes

dselman (Sun, 09 Jul 2017 10:00:51 GMT):
That's good. They are running. :-)

coder-ajay (Sun, 09 Jul 2017 10:01:15 GMT):
so if i face this again, i should run this command to check if the dockers are running... right?

dselman (Sun, 09 Jul 2017 10:01:27 GMT):
You can use `docker logs` to view the logs from each of the containers. The chaincode container (the one with `vehicle-lifecycle-demo` in the name is where your code is running).

rerun the ./startFabric.sh script to restart everything and then run `composer network deploy` to deploy your network

The rest server probably times out after some if machine is inactive. Followed below steps and things seem to be working for now... 1. Run: ``` docker kill $(docker ps -q) docker rm $(docker ps -aq) docker rmi $(docker images dev-* -q) ``` Killing existing containers seems to be most important step. Else, the error persists. 2. Run: ` npm install ` 3. _cd dist_ > run ` composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString ` (with correct .bna file name) 4. Run: ` composer-rest-server ` These steps are helping most of the time.

mahoney1 (Mon, 10 Jul 2017 07:22:37 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=ihNTziknrCBCSRWiZ) @coder-ajay it is related in the sense that the chaincode docker container with name `vehicle-lifecycle-network`is removed (hence the REST server complaining on startup where you specify the '-n' parameter) and that was created when the business network was deployed initially. So given you've deployed 'my-network' you'll see a container for that in `docker ps -a` output

coder-ajay (Mon, 10 Jul 2017 07:25:24 GMT):
Okay. Thanks @mahoney1 . Things seem to going good as of now.

dselman (Mon, 10 Jul 2017 07:26:43 GMT):
@coder-ajay where you able to get any logs from the vehicle-lifecycle container?

coder-ajay (Mon, 10 Jul 2017 07:28:20 GMT):
@dselman ... i run ` docker logs ` ... but its asking for parameters. I am missing something.

hi, in the context of a Fabric network, is it possible to use the same Couchdb container for multiple peers or each peer claims its own Couchdb container?

dselman (Mon, 10 Jul 2017 07:35:10 GMT):
Each peer has its own CouchDB. The peers can operate independently.

dselman (Mon, 10 Jul 2017 07:36:13 GMT):
@coder-ajay to grab logs you do `docker logs `. You can get the containerId from the `docker ps -a` command.

@mahoney1 referring to the namespace problem, "aside from the resolution of --> Banka banka (which may be elsewhere defined in your model file) it looks good. If you don't have a local playground installed, you can if you wish, validate your model in http://composer-playground.mybluemix.net/editor - it will highlight any exceptions (assuming you've not validated it already). One thing to note: the error above says 'failed to find namespace net.croz ' - in your model file the namespace is defined as namespace net.croz.blockchain - can you check the js files if you're using a shortened reference, @param maybe?

@wael did you run `composer identity import` to import the PeerAdmin certificate?

PeerAdmin is not a user defined on the Fabric CA and so it cannot "enrol" - you must get and import the certificates manually

[ ](https://chat.hyperledger.org/channel/composer?msg=zKvH44D7ya54EEkbx) @wael in addition to @sstone1 post ; with the default Composer dev Fabric setup, you use PeerAdmin to deploy the network ; you use 'admin' thereafyter to interact with it - eg. operations like 'connect', 'ping' etc https://hyperledger.github.io/composer/business-network/bnd-deploy.html

mahoney1 (Mon, 10 Jul 2017 13:53:38 GMT):

sstone1 (Mon, 10 Jul 2017 13:59:54 GMT):
@wael you should import it before you attempt to use the PeerAdmin identity to deploy the network. the admin identity is not a peer administrator nor a channel administrator and does not have the fabric permissions required to deploy chaincode.

@elrond - in your .bna file, your permissions.acl file needs to be corrected, you're missing the '.*' like so - ```rule Default { description: "Allow all participants access to all resources" participant: "ANY" operation: ALL resource: "net.croz.blockchain.**" action: ALLOW }``` Then recreate the archive using `composer archive create --sourceType dir --sourceName . -a ./dist/my-network.bna` ie your bna filename etc etc and try to deploy that.

@here We have an external process (chokidar file watcher) which needs to integrated on node server (in this case composer rest server). What is the best way to approach this ?. Do you think it okay to add code on rest server to handle this ?.

@Sandeep it seems a bit strange to integrate a file watcher into the REST server? can you explain what you are using the file watcher for?

Sandeep (Mon, 10 Jul 2017 18:05:41 GMT):
@sstone1 We have a some files that come from SAP that needs to be sent to blockchain. When SAP places these files on a share drive, the node server should pick up and put them on blockchain. Does that make sense ?

Sandeep (Mon, 10 Jul 2017 18:05:41 GMT):
@sstone1 We have files that come from SAP that needs to be saved to blockchain. When SAP places these files on a share drive, the node server should pick up and put them on ledger. Does that make sense ?

Sandeep (Mon, 10 Jul 2017 18:11:42 GMT):
@sstone1 In addition to that, we have a scenario where the approval request from the UI needs to be digitally signed by the user's private key before storing it on the ledger. To implement any of these external process, We are thinking about what would the best approach be.

@Sandeep yeah - the integration with SAP makes sense

sstone1 (Mon, 10 Jul 2017 18:45:18 GMT):
but i do not think you want to put that integration process (files -> REST server) into the REST server - i think you should manage it as an external process

RobertGarrett (Mon, 10 Jul 2017 18:47:27 GMT):
if anyone has any experience with the node-red hyperledger composer nodes (with composer v0.9.1) I would be super thankful for any expertise/opinions on this issue! https://stackoverflow.com/questions/45016176/unexpected-output-with-node-red-contrib-composer-nodes-in-composer-v0-9-x?answertab=oldest#tab-top

Sandeep (Mon, 10 Jul 2017 19:03:18 GMT):
@sstone1 . Thanks. One more question. Is there any REST endpoint we can use to issue an identity to a participant ?. I can only see the CLI command to issue identity. We have a UI screen where an admin needs to issue an identity to a participant on the network.

sstone1 (Mon, 10 Jul 2017 19:03:39 GMT):

@mahoney1 I finally was able to deploy to bluemix fabric. One question do you know if composer-rest-server will work using a profile pointing to bluemix?

anarancio (Mon, 10 Jul 2017 20:23:16 GMT):
seems it works but you have to use a different user than the one you used to make the deploy (at least with the same user didn't worked for me)

mahoney1 (Mon, 10 Jul 2017 20:53:24 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=gRzkkD3o34GESHB6a) @anarancio it should do - this doc gives you an idea (including ENV variables) for deploying it in a production level. In particular, the info about what connection profile it uses.

mahoney1 (Mon, 10 Jul 2017 22:32:23 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=iPWadDDAzk3RJ5YER) @DennisM330 cool. Randomstring does nothing, its just fulfilling the -s param (PeerAdmin is pre-enrolled so there's no secret per se)

DennisM330 (Tue, 11 Jul 2017 00:07:13 GMT):
Is there a way aside from developer a client, to look at events emitted a result of a transaction? I have an a event defined in the composer model and updated one of my transactions to emit the event. The invocation of the transaction via the composer-rest-server succeeds. Doing a docker logs on the chaincode peer shows 2017-07-11 00:01:10.656 UTC [Composer] Debug -> DEBU 2422 Emitting event from EventService.transactionCommit []

DennisM330 (Tue, 11 Jul 2017 02:04:47 GMT):

dselman (Tue, 11 Jul 2017 07:10:49 GMT):
Fabric does not yet support undeploying chaincode (stopping/removing the chaincode container). Use `composer network update` to update the contents of an existing network, or increment the version number of the network in package.json and use `deploy`

baoyangc (Tue, 11 Jul 2017 07:46:00 GMT):
we want use it as an http server

dselman (Tue, 11 Jul 2017 07:46:07 GMT):
The arguments are printed at startup (after you complete the forms)

baoyangc (Tue, 11 Jul 2017 07:46:08 GMT):
but without oauth login

baoyangc (Tue, 11 Jul 2017 07:46:45 GMT):
yes i know the command:` composer-rest-server -p hlfv1 -n banquanjia -i PeerAdmin -s abcd -N never`

dselman (Tue, 11 Jul 2017 07:46:48 GMT):
``` Options: -p, --connectionProfileName The connection profile name [string] -n, --businessNetworkName The business network identifier [string] -i, --enrollId The enrollment ID of the user [string] -s, --enrollSecret The enrollment secret of the user [string] -N, --namespaces Use namespaces if conflicting types exist [string] [choices: "always", "required", "never"] [default: "always"] -P, --port The port to serve the REST API on [number] -S, --security Enable security for the REST API [boolean] [default: false] -h, --help Show help [boolean] ```

dselman (Tue, 11 Jul 2017 07:47:08 GMT):
So `-S false` would do it

baoyangc (Tue, 11 Jul 2017 07:47:51 GMT):
yes . i see.

coder-ajay (Tue, 11 Jul 2017 07:48:41 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=L2CQYGtjrHbQedAf3) @mahoney1 ok. How is data maintained in real world data managed? Is this done with some database and services?

baoyangc (Tue, 11 Jul 2017 07:49:49 GMT):
in -S false mode, how composer-rest-server know which participant is creating an asset or make transaction

baoyangc (Tue, 11 Jul 2017 07:50:09 GMT):
is there a login method in this mode

baoyangc (Tue, 11 Jul 2017 07:50:11 GMT):
?

dselman (Tue, 11 Jul 2017 07:52:33 GMT):
Using the `-i` enrollment id

dselman (Tue, 11 Jul 2017 07:52:44 GMT):
All transactions will be processed using that id

baoyangc (Tue, 11 Jul 2017 07:53:36 GMT):
i mean make transaction with http API of composer-rest-server

baoyangc (Tue, 11 Jul 2017 07:53:53 GMT):
not in command line

dselman (Tue, 11 Jul 2017 07:54:13 GMT):
Yes -- that is the id that will be used

dselman (Tue, 11 Jul 2017 07:54:24 GMT):
What else could it be? :-)

baoyangc (Tue, 11 Jul 2017 07:54:48 GMT):
i see, composer-rest-server -i enrollId

baoyangc (Tue, 11 Jul 2017 07:54:56 GMT):
you mean this enrollId?

dselman (Tue, 11 Jul 2017 07:55:03 GMT):
yes

baoyangc (Tue, 11 Jul 2017 07:55:05 GMT):
got it

baoyangc (Tue, 11 Jul 2017 07:57:17 GMT):
this enrollId could be connected with an participantId.

baoyangc (Tue, 11 Jul 2017 07:57:50 GMT):
all operation is done by this participantId

dselman (Tue, 11 Jul 2017 07:59:06 GMT):
yes

dselman (Tue, 11 Jul 2017 07:59:17 GMT):
using `composer identity issue`

shidosan (Tue, 11 Jul 2017 08:10:50 GMT):
Hello to all community members. I have a beginner level question. I am planning to write a PoC app on Hyperledger Composer and was thinking what would be a setup to connect to local Hyperledger Fabric as 2 different kind of participants to test the PoC? Any help is appreciated.

dselman (Tue, 11 Jul 2017 08:14:17 GMT):
For POC you can use the Fabric development server installed by Composer. You can then create 2 participants and issue them identities (certificates). https://hyperledger.github.io/composer/managing/participantsandidentities.html

shidosan (Tue, 11 Jul 2017 08:30:16 GMT):
@dselman Thank you very much! The documentation is more about creating and managing identities for participants. It does not say anything about connecting to the network as a newly created participant.

dselman (Tue, 11 Jul 2017 08:34:22 GMT):
issuing an identity for a participant creates an enrollment id that can be used to connect

shidosan (Tue, 11 Jul 2017 08:53:57 GMT):
@dselman Oh, I got it, you can then use the enrollment id and secret to connect to BN using either composer REST API or composer-client via Node app. Thank you very much again! I hope one day I can be as helpful as you in this community :)

dselman (Tue, 11 Jul 2017 08:55:01 GMT):

github authentification not working, im not getting the 401 error, its letting me pass through normally?

levinkwong (Tue, 11 Jul 2017 10:12:32 GMT):
Hi guys, I have the following *Person* and *VIP* participant and have a *setupTransaction* to create a participant: ``` participant Person identified by personId { o String personId o DateTime dateOfBirth } participant VIP extends Person { } transaction Setup { } function setupTransactionProcessor(setupTransaction) { var factory = getFactory(); var NS = 'com.app'; var harry= factory.newResource(NS, 'VIP', "Harry"); return getParticipantRegistry(NS + '.VIP') .then(function(vipRegistry) { return vipRegistry.add(harry); }) } ``` After I submit a setup transaction, it returns success. But when I `composer network list`, it shows error ``` error trying to query chaincode. Error: chaincode error (status: 500, message: Error: Instance com.app.VIP#Harry missing required field dateOfBirth) ``` I can understand the error but *WHY* the setupTransaction do not throws error at that moment? Is it related to the `extends`?

baoyangc (Tue, 11 Jul 2017 10:25:19 GMT):

levinkwong (Tue, 11 Jul 2017 11:01:37 GMT):
@mahoney1 Does that mean since the 'getter' was not executed when I add my VIP object, it is ok. But when I try to list the objects, the composer tries to 'get' the value from that object, then it returns error because it is empty.

coder-ajay (Tue, 11 Jul 2017 11:02:03 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Dr8Gg5L8XuoNxk9vX) @mahoney1 Ok. Thanks for the links.

mahoney1 (Tue, 11 Jul 2017 11:08:23 GMT):
the network is ultimately deployed (via your HLF connection) to the endorsing peers in your Fabric runtime and there is an example of multi-org peers using a multi-org channel here -> http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html.

mahoney1 (Tue, 11 Jul 2017 11:18:35 GMT):

levinkwong (Tue, 11 Jul 2017 11:20:22 GMT):
@mahoney1 But my asset is created with the current schema

levinkwong (Tue, 11 Jul 2017 11:21:00 GMT):
with a missing mandatory field

[ ](https://chat.hyperledger.org/channel/composer?msg=QmThMQxuWv3ASGsgC) @levinkwong right, so the required field was already in the schema for the deployed network prior to you submitting the txn ; it does seem strange, will look into this.

levinkwong (Tue, 11 Jul 2017 11:35:39 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=zJrkirpoqZTcXBmr7) @mahoney1 albeit with a different network (basic sample network) - we could not replicate your error in v0.9.1 when trying to submit a transaction from client code or using playground, and thus composer network list - the only time we see it is if an object was added before, the schema was changed to make the property required - then composer network list 'complains' about the instance). Could you raise a Stack Overflow ticket please and attach everything including your network, thank you

@levinkwong the data should have been validated before it was persisted. We may have a bug... I will look into how you were able to persist invalid data

dselman (Tue, 11 Jul 2017 12:36:43 GMT):
@levinkwong ... you need to add a `harry.dateOfBirth = new Date()` or something when you create your asset

@levinkwong ... you need to add a `harry.dateOfBirth = new Date()` or something when you create your participant

Now, navigate to the REST API explorer at http://localhost:3000/explorer/. If security has been successfully enabled, any attempts to call one of the business network REST API operations using the REST API explorer should be rejected with an HTTP 401 Authorization Required message i am not getting the error message, although it is connected to the auth service because visiting the link "http://localhost:3000/auth/github" asks me for authorization

elrond (Tue, 11 Jul 2017 12:38:29 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=GEGNm2BzKoCY4H724) @uber.twin under ~/.composer-credentials your enrollment certificate would be imported into the local composer KeyValStore. The Admin's crypto material (eg., PeerAdmin) needs to be available to deploy a business network (the Developer tools install page on our docs site discusses pulling down the fabric-dev-servers scripts which does the PeerAdmin import as part of the setup . hlfv1 refers to a profile subdirectory under .composer-connection-profiles.

mahoney1 (Tue, 11 Jul 2017 16:16:02 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Az7XpmyJQn4Z6GgrH) @jmcnevin hi there - is there an implementation reason why you would want to change location - am interested to know, that's all as the credentials dir is also in the users directory. But you could in theory use COMPOSER_CONFIG environment variable eg. ```Connection profiles are also loaded from the COMPOSER_CONFIG environment variable. This should be a JSON string with a root connectionProfiles key, with a set of connection profiles indexed by name. Eg. you can add this to a Docker compose YAML file - note the example below is a v0.6 connection profile, but you get the picture: environment: COMPOSER_CONFIG: > { "connectionProfiles": { "hlfabric": { "type": "hlf", "keyValStore": "/home/composer/.composer-credentials", "membershipServicesURL": "grpc://membersrvc:7054", "peerURL": "grpc://vp0:7051", "eventHubURL": "grpc://vp0:7053", "deployWaitTime": 300, "invokeWaitTime": 30 } }, "credentials": { "hlfabric": { "admin": "Xurw3yU9zI0l" } } }```

[ ](https://chat.hyperledger.org/channel/composer?msg=3xnsNmjJovb5qon44) @shidosan think you need to specify the resource you're denying eg `participant: "com.acme.network.Admin#bob@example.com"

Joseph (Tue, 11 Jul 2017 17:08:18 GMT):
Before I upgraded to the latest composer version v0.9.1, I would test my network assumptions by putting the BNA on composer playground local, but recently, I noticed that it started allowing transactions / assets to be submitted for participants that are not explicitly defined beforehand. Is this working as designed?

sstone1 (Tue, 11 Jul 2017 17:17:32 GMT):
do you mean participants that are referenced in the JSON input for the transaction?

sstone1 (Tue, 11 Jul 2017 17:18:07 GMT):
e.g. your JSON includes: `"participant": "resource:org.acme.Participant#FRED"`

Joseph (Tue, 11 Jul 2017 17:19:05 GMT):
Yep! exactly...

Joseph (Tue, 11 Jul 2017 17:24:59 GMT):
More details: So the asset I have is a loan between two people, a borrower and a lender. And so in the cto file, my loan asset references (-->) these two participants.

Joseph (Tue, 11 Jul 2017 17:25:25 GMT):
So I submit this in playground "create asset"

Joseph (Tue, 11 Jul 2017 17:25:33 GMT):
{ "$class": "com.innovate.iloanate.Loan", "loanID": "loanID:0003", "loanStatus": "LOAN_CREATED", "loanRequestDate": "", "loanDuration": "", "loanAmount": 0, "borrower": "resource:com.innovate.iloanate.Borrower#memberId:8896", "lender": "resource:com.innovate.iloanate.Lender#memberId:1081" }

Joseph (Tue, 11 Jul 2017 17:26:05 GMT):
And it let it go through even though neither that borrower or lender has been defined...

sstone1 (Tue, 11 Jul 2017 17:26:13 GMT):
so, that is expected

sstone1 (Tue, 11 Jul 2017 17:26:23 GMT):
we're doing a lot of work on cleaning up our security model at the moment

sstone1 (Tue, 11 Jul 2017 17:26:48 GMT):
part of this is being able to cope with things that you do have access to, where those things relate to other things that you do not have access to

sstone1 (Tue, 11 Jul 2017 17:27:37 GMT):
before we tried to resolve the entire asset/participant graph and threw an error if any part of it could not be accessed (either due to it not existing or not having access)

Joseph (Tue, 11 Jul 2017 17:28:03 GMT):
oh so that's why before this would not have worked for me...

sstone1 (Tue, 11 Jul 2017 17:29:23 GMT):
yeah

sstone1 (Tue, 11 Jul 2017 17:29:37 GMT):
so now, any relationships that cannot be resolved are replaced with `InvalidRelationship` objects

sstone1 (Tue, 11 Jul 2017 17:30:02 GMT):
we're missing a good way to "check" to see if a relationship is valid or not

sstone1 (Tue, 11 Jul 2017 17:30:13 GMT):
but if you try and access any properties of an `InvalidRelationship`

sstone1 (Tue, 11 Jul 2017 17:30:26 GMT):
for example: `loan.borrower.socialSecurityNumber`

sstone1 (Tue, 11 Jul 2017 17:30:30 GMT):
then an error will be thrown

sstone1 (Tue, 11 Jul 2017 17:30:53 GMT):
`loan.borrower.memberId` is OK though, as we know the identifier

sstone1 (Tue, 11 Jul 2017 17:31:10 GMT):
we really need a `isValid(loan.borrower)` to test relationships point to real things

Joseph (Tue, 11 Jul 2017 17:39:30 GMT):
Yes!

Joseph (Tue, 11 Jul 2017 17:40:57 GMT):
@sstone1 Could I define a rule in permissions.acl that would prevent this from happening?

sstone1 (Tue, 11 Jul 2017 17:45:01 GMT):
you could do - just try accessing a property of the relationship

sstone1 (Tue, 11 Jul 2017 17:46:20 GMT):
``` rule R7 { description: "The owner of a vehicle can update the vehicle" participant(p): "systest.accesscontrols.SampleParticipant" operation: UPDATE resource(loan): "systest.accesscontrols.Loan" condition: (loan.borrower.socialSecurityNumber && otherConditions) action: ALLOW } ```

sstone1 (Tue, 11 Jul 2017 17:46:28 GMT):
i'll look at adding the `isValid`

sstone1 (Tue, 11 Jul 2017 17:46:43 GMT):
you should just be able to have `condition: (isValid(loan.borrower))`

Joseph (Tue, 11 Jul 2017 17:48:08 GMT):
Cool! Thank you :)

Joseph (Tue, 11 Jul 2017 18:25:45 GMT):
Does anyone have a running example of using the queries.qry file that they can share?

Joseph (Tue, 11 Jul 2017 18:34:12 GMT):

Joseph (Tue, 11 Jul 2017 19:02:13 GMT):
Awesome @dselman! So just took a look at the example. Question: So do I need to define a transaction for each query?

dselman (Tue, 11 Jul 2017 19:02:53 GMT):
No - if you look at the unit test you can see it is calling queries from the client side

DennisM330 (Tue, 11 Jul 2017 19:02:55 GMT):
Is there a way in the Node Red Hyperledger Composer In node to retrieve the payload of an event? I tried to load msg.payload but that gets an Undefined in the Debug tab.

dselman (Tue, 11 Jul 2017 19:04:43 GMT):
It looks like the full JSON for the event should be displayed:

dselman (Tue, 11 Jul 2017 19:04:48 GMT):
``` node.log('received event ' + JSON.stringify(deserializedEvent)); node.send(deserializedEvent); ```

dselman (Tue, 11 Jul 2017 19:05:05 GMT):

There was a study that noted that in version 0.6 hyperledger fabric's scalability was called into question as they found a limit to only 16 nodes. I know they intended on addressing this problem in version 1.0 but does anyone have any insight on whether that was accomplished. Here is the link to that article I am referencing (see part 4: Performance Benchmarking) ttps://arxiv.org/pdf/1703.04057.pdf

@fh48 this is a syntax error in one of your files. Probably using a `-` in an identifier. Opening the files in VSCode with the Composer extension may help you find this.

@reggiefelias you would have to webpack the crypto library so it can be included as a .js file inside the business network archive.

[ ](https://chat.hyperledger.org/channel/composer?msg=ejoBHBmrjohXX2G2k) @seungchan not exactly, there's no real fabric application, we usually deploy chaincode or smart contracts into Fabric (these are usually coded in Go), so Composer helps to develop these chaincode/smart contracts using the Composer Business Network Definition (composer modelling/javascript) , composer also has a rest-server to quickly spin up a RESTful API server (based on Loopback) and also generate a basic Angular front-end

shidosan (Wed, 12 Jul 2017 09:13:39 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=mteZ5KxutS4jruAD4) @JonathanTan Sure, I don't see why not. I suppose you could call composer-rest-server APIs once they are generated using third party libraries to build up your application.

Hello, using fabric-client, how can I get a list of all transactions (even the creation of assets etc...) of the blockchain? bizNetworkConnection.getTransactionRegistry() only returns the transactions that have been call explicitly. I can get the transactions when I create a Participant or an Asset

[ ](https://chat.hyperledger.org/channel/composer?msg=nnfg4eLpSaq2GhNmb) @dselman I understand that part (from the connection.json). What I don't understand is how NodeRed knows how to get to my Composer if it's on another server. Which it is in this case. NodeRed is running on a laptop and Composer is on a z server. Can you not use these nodes in that case?

caroline-church (Wed, 12 Jul 2017 13:43:34 GMT):
Hi @JennFoley The name of the connection profile that you use on your node must be one which is on the machine that you are running the node red nodes from so in your case your laptop. In that connection profile the urls that you specify for the location of the peers etc this would point to the server

JennFoley (Wed, 12 Jul 2017 13:46:00 GMT):
Hi @caroline-church. Thanks! Does that mean I would: 1) Copy my connection.json to the server and modify it to not say localhost but instead the remote server IP OR 2) Have to install Composer local to NodeRed

@JennFoley neither, so when you install the composer node red nodes that depends on composer so will pull in the required npm packages.

Hi, Composer community, we are implementing business use cases using blockchain, and we find composer convenient for our needs. However, we are implementing some new privacy techniques, for which we are poking at the chaincode level. We are doing it fine by directly writing our own chaincode without using fabric-composer and deploying on the default 4 peer configuration of hlfv1. For more complex business use cases, we thought of leveraging the composer to generate the chaincode and datamodel, and then poke our stuff on the chaincode. When I do `composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString`, I am not able to figure out how the chaincode is deployed, where the code is, and whether it too abstract or readable enough. Thank You.

Hi, Composer community, we are implementing business use cases using blockchain, and we find composer convenient for our needs. However, we are implementing some new privacy techniques, for which we are poking at the chaincode level. Before using composer, we were writing our own chaincode (with the privacy sauce) and deploying on the default 4 peer configuration of hlfv1. For more complex business use cases, we thought of leveraging the composer to generate the chaincode and datamodel, and then poke our stuff on the chaincode. Otherwise, we need to manually write chaincode / docker-compose files for each use-case, and its a pain. When I do `composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString`, I am not able to figure out how the chaincode is deployed, where the code is, and whether it too abstract or readable enough. What approach do you recommend? Thank You.

kletkeman (Wed, 12 Jul 2017 14:57:46 GMT):
Question: If I want to write a generic component that routes messages to the blockchain and if I want to support HLComposer as one of the possible chaincode targets, would I have to deploy an instance of the REST server per BNA? Or would one instance be able to service many BNAs? @dselman @sstone1 Note that one aspect of my question has to do with the end to end flow control requirement imposed by Fabric v1 to avoid late failures on key collissions.

@ThomasBouquet Figuring they allow it, but you'd need a different docker-compose.yml file. Some come with the fabric. Then when you do network deploy, it'll deploy across all of the peers

For queries, can I do a SELECT that is almost like a JOIN. For example, I have a relationship between a Part asset and a Supplier participant. I want to select all Part Numbers and then JOIN with the Suppliers where Supplier ID = $Param. A part number has a relationship to a Supplier. A supplier has a Supplier ID. I may want to subquery that with Suppliers in the State of New York for example

Does the Composer shield you from all the details of working with the SDK such as working with RW Sets and the Ordering Service if you look at the 7 steps of a transaction? If so, are there scenarios when I might need to drop down to the using the SDK?

sstone1 (Wed, 12 Jul 2017 21:41:01 GMT):
@DennisM330 no JOINs yet. we know people want to be able to query over relationships, but this is difficult as CouchDB does not support JOINs.

Also, I'm curious in the Compose Playground, if you have multiple bna's deployed that create different business network ID's (intentional because they're different), could you access them from the Composer Playground? Currently, I can only access one but there is nothing in the start up or connection profile that specify which one it should use. I also haven't restarted it since I deployed the newest BNA.

Hi all! I've been messing around with Hyperledger Fabric for a couple weeks now, and I just recently started to look into Fabric Composer. From what I understand, Composer is intended to help make Fabric application development easier for developers. Is this true, and are there other benefits to using it? With that in mind, are there any downsides to using Composer versus doing all of the development manually (in terms of flexibility, performance, etc.)? I'm trying to help my team decide which direction to take.

amaclean (Thu, 13 Jul 2017 09:04:42 GMT):
@harj91 Your client composer version is a different version than when the chaincode was deployed. I had a similar problem, revert back to 0.8.0 with "npm install -g composer-cli@0.8.0". It should then work, otherwise you can undeploy your network, update composer followed by re-archiving and re-deploy your network (but you can expect a few errors to fix in your network definition).

amaclean (Thu, 13 Jul 2017 09:07:27 GMT):
@pancake weird error, I'm running 0.9.1 and -a parameter works for me.

@pancake there is no Composer 1.5, where did you install Composer from?

sstone1 (Thu, 13 Jul 2017 09:08:27 GMT):
it looks like you have a completely different product installed :)

sstone1 (Thu, 13 Jul 2017 09:12:32 GMT):
@tallharish Composer does *not* generate chaincode. there is a generic chaincode (10% Go, 90% JavaScript) that understands business network definitions. can you talk more about these privacy features that you're adding, and why Composer access control lists do not solve the problem? are these encryption features?

pancake (Thu, 13 Jul 2017 09:13:30 GMT):
Oh, this composer does not mean `php composer` right?:joy:

I've got a problem trying to getParticipantRegistry by following the docs. The error is "networkDefinition.getParticipantRegistry is not a function". Is this expected, or is the code faulty?

amaclean (Thu, 13 Jul 2017 09:19:29 GMT):
```const BusinessNetworkConnection = require('composer-client').BusinessNetworkConnection; var networkConnection = new BusinessNetworkConnection(); networkConnection.connect('hlfv1', 'academic-network', 'PeerAdmin', 'adminpw') .then(function (networkDefinition) { return networkDefinition.getParticipantRegistry('academicnet.Registrar'); }) .then(function (registrarRegistry) { return registrarRegistry.getAll(); }) .then(function (registryParticipants) { console.log(registryParticipants); }) .catch(function (error) { console.log(error.message); });```

[ ](https://chat.hyperledger.org/channel/composer?msg=rnmXK23W3FxqqaCvi) @harj91 Your client composer version is a different version - you should undeploy your network with `composer network undeploy` then with v0.9.1 composer level re-archive your network `composer network archive` and then re-deploy your network (ts possible you may have to fix a few errors in your network definition, test it in Composer playground https://composer-playground.mybluemix.net/)

mahoney1 (Thu, 13 Jul 2017 09:43:56 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=feX6nyTHXhRWzgeL4) @amaclean some observations - you would normally return NetworkConnection eg. businessNetworkConnection.getParticipantRegistry() not networkDefinition - see 'Write Unit Tests' here for an example -> https://hyperledger.github.io/composer/tutorials/developer-guide.html also 2) is your registry academicnet or academic.net and 3) networkConnection.connect () should not use PeerAdmin - that's for network deploys only - try 'admin' for example.

[ ](https://chat.hyperledger.org/channel/composer?msg=qrJ5DMzv9f99TPccj) @baoyangc would have to see your composer network deploy command - possibly an error in comms with the Orderer - can you include a `docker ps -a` - also the docker logs for the chaincode container would be good.

Hi, I am trying to extend the Composer environment to add additional Organisations and Peers. I could add it and the network is up and running. When I try to deploy the *.bna file, in the network composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString I am getting below error. Error: error trying deploy. Error: error trying install chaincode. Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com") Command failed I can see PeerAdmin under fabric-tools/fabric-scripts/hlfv1/composer/creds folder. Which is not matching with my modification. Looks like I need to create a new Enrolment Id & Secret. How can I create a new Enrolment Id & Secret in Composer environment?

[ ](https://chat.hyperledger.org/channel/composer?msg=NchYkA7GX3shgDxdz) @camdenT hi camden T and welcome - yes "Hyperledger Composer" to give it its correct name is intended to make life easier developing blockchain use cases, whether app development as you say or integrating with existing systems. Its toolset includes a modeling playground for modeling the business network and testing it, with or without a running Fabric in situ. It also includes generators to accelerate developing use cases. Finally, the modeling language and framework enables to you think about developing for longer-term production use cases (eg. applications and integration challenges) and not be sidetracked or derailed in your app dev quest with the complications of understanding network infrastructure or how to engage with a Fabric blockchain itself.

[ ](https://chat.hyperledger.org/channel/composer?msg=wfug5mdaLyrzr5L57) @geoms its very strange, as PeerAdmin is pre-enrolled. Can you do a teardown of your docker dev images, and startFabric.sh then createComposerProfile.sh - something is not right here. I would regenerate the archive file to deploy the network once your network is up

Can Java be used with hyperledger composer to integrate with the hyperledger fabric I know you could use a Java application to issue HTTP requests to the composer-rest-server but I am guessing you cannot use Java directly and need to use the Composer JavaScript APIs. Asking on behalf of some Java developers who were asking me

DennisM330 (Thu, 13 Jul 2017 12:53:47 GMT):
The other option would be to use the Hyperledger Fabric Java SDK, correct?

[ ](https://chat.hyperledger.org/channel/composer?msg=MaB3LLgzoyzpei269) @geoms hi there thanks for the docker ps -a - so you're running with composer v0.9.1 and you need to *x86_64-1.0.0-rc1* Hyperledger Fabric v1.0 RC1.for v0.9.1 - and you are using older Fabric images x86_64-1.0.0 that syncs with an earlier release of composer - so 1) pull down the new fabric-dev-scripts (see here for info https://hyperledger.github.io/composer/installing/development-tools.html ) 2) perform a teardown.sh 3) remove your old docker *images* 4) downloadFabric,sh (from within fabric-tools of your new scripts 5) startFabric.sh 6) createComposerProfile.sh (for the new env) - your network archive bna should be already 'good' to try deploying with PeerAdmin after.

@mahoney1 I provided the user admin and secret adminpw. I'm guessing it has something to do with my authentication or implementation. So the SecurityContext is not an issue when you successfully connected to the deployed network? Maybe it's because I have not explicitly configured any credentials.

Hi all, I am working on a web app for a business use case network on Hyperledger Fabric. I have my business network deployed and can access it using Composer REST Server. It is running on a Linux on Z image. I have another server for the web app making REST calls to the Composer REST Server, and it works well. I was wondering if there is a way to SSL enable the REST Server, and if so, how can I do it? I will attach a diagram of my setup. Thanks!

@sstone1 @mahoney1 hi, I am not sure I understand how the ACL rules are effective at enforcing the access restriction. Isn't it true that each organization has it's own "admin" user which is omnipotent over the whole network? I guess there could be one entity holding all "admin" users which will create Participants for each organization and than distribute the corresponding identities to org level users?

None of the admin users will be allowed in unless their certificates are bound to a participant.

mahoney1 (Thu, 13 Jul 2017 17:21:43 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=zWDoYQKbXe33xFgcc) @uber.twin So for ACLs, currently Composer disables ACL enforcement when a certificate with a Common Name (CN) with the word 'admin' in it is used to submit transactions to the Blockchain. This behaviour is a hangover from Hyperledger Fabric v0.6, and we are making changes to remove this "feature". This applies to `admin`, `PeerAdmin`, `WebAppAdmin`, etc. The idea being that once all those changes (see issues below) go in, when you deploy a business network you will have to define at least one bootstrap participant who is issued or bound to a Blockchain identity (certificate). After deployment, you will have to use a Blockchain identity for a bootstrap participant to interact with the deployed business work.

[ ](https://chat.hyperledger.org/channel/composer?msg=46zTPt9izCouotF6D) @JGraft you should generate the ID client side (using UUIDs for example) and pass that into the Composer APIs. the only safe, deterministic way to "generate" an ID on the Blockchain side in a Composer transaction processor function is to use the transaction ID.

```# turn off security for the peer AdminPrincipal: Role.MEMBER``` this appears in the configtx.yaml . why we need set this?

baoyangc (Fri, 14 Jul 2017 08:45:31 GMT):
the scripts in ` fabric-dev-server ` can't create an fabric network with TLS enabled.

mahoney1 (Fri, 14 Jul 2017 08:45:48 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=jxW4sfmNCgwrWqw7Y) @seungchan yes big difference - that doc link refers a YAML for configuring up a Hyperledger Fabric blockchain network. A Composer *Business* Network Definition defines the structure of the resources (using a domain specific language that use concepts that describe real business networks) that will be stored on the ledger, such as assets, participants, or indeed processed as/by transactions. Once you define your BND (to define the domain data model for the business network itself) developers can capture _smart contracts_ as executable transaction processor functions (written in JavaScript). This Composer business network definition gets deployed *onto* the underlying runtime Hyperledger Fabric blockchain network.

ThomasBouquet (Fri, 14 Jul 2017 08:45:49 GMT):
@baoyangc Thank you ! When we connect to the composer is it only with one organisation as we have to specify multiple connection.json files ?

ThomasBouquet (Fri, 14 Jul 2017 08:46:47 GMT):
@baoyangc what is TLS ?

baoyangc (Fri, 14 Jul 2017 08:47:36 GMT):

baoyangc (Fri, 14 Jul 2017 08:47:40 GMT):

did you success deploy bna to the fabric ? I tried several days ,but failed.

mahoney1 (Fri, 14 Jul 2017 08:53:51 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=q5HSk3AZFeXYTsy3s) @baoyangc correct, it sets up a default Fabric (dev) environment (non-TLS)

mahoney1 (Fri, 14 Jul 2017 08:53:51 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=q5HSk3AZFeXYTsy3s) @baoyangc correct, it sets up a default Fabric (dev) environment (non-TLS) - see more in Hyperledger Fabric Samples on configtx.yaml here -> https://media.readthedocs.org/pdf/hyperledger-fabric/latest/hyperledger-fabric.pdf on your Fabric question relating to configtx.yaml -> AdminPrincipal dictates the type of principal used for an organization's Admins policy. Today, only the values of Role.ADMIN and Role.MEMBER are accepted, which, oddly enough, indicates a principal of role type ADMIN and role type MEMBER respectively.

baoyangc (Fri, 14 Jul 2017 08:55:31 GMT):
in TLS environment , do we need to set another value for `AdminPrincipal`?

davidkel (Fri, 14 Jul 2017 08:56:54 GMT):
@baoyangc The fabric development server was designed to be a simple entry point to using a real fabric. So we explicitly disabled any need for Admin roles where we could and also explicitly did not use TLS to keep things as simple as possble. Note that the AdminPrincipal setting is not relevant to TLS whatsoever.

ThomasBouquet (Fri, 14 Jul 2017 08:57:55 GMT):
@baoyangc For 3 organisations, i need to create connection1.json, connection2.json and connection3.json ?

davidkel (Fri, 14 Jul 2017 08:57:59 GMT):
@baoyangc If you want to create a more complex fabric runtime setup then I would suggest following the fabric documentation rather than using our development server as a template as it isn't our intention to show how to build fabric setups

baoyangc (Fri, 14 Jul 2017 09:01:46 GMT):
can `composer identity import ` be used in TLS enabled environment?

baoyangc (Fri, 14 Jul 2017 09:01:49 GMT):
@davidkel

davidkel (Fri, 14 Jul 2017 09:03:00 GMT):
@ThomasBouquet The connection profile defines how you from your organisation would interact with a single business network which could have been deployed to a consortium of multiple organisations. This is why a connection profile has an MSPid as it represents your organisations MSPid. You can define peers from other organisations in your connection profile when you want to submit a transaction and you need endorsements from those organisations. The important difference is deployment of a business network. Individual organisations would be expected to deploy the business network to the Peers for which they are allowed to do so (People in one organisation would not be allowed to deploy a business network to other organisation peers) so the likelyhood is that you would have a connection profile for deploy and another for submitting transactions.

davidkel (Fri, 14 Jul 2017 09:03:28 GMT):
@baoyangc yes because it doesn't have anything to do with TLS setup of a fabric

coder-ajay (Fri, 14 Jul 2017 09:12:56 GMT):
Hi, in the vehicle-lifestyle-network, i couldn't see .cto file where assets, participants or business network definition are mentioned. Is this as expected?

ThomasBouquet (Fri, 14 Jul 2017 09:15:32 GMT):
@davidkel Hi, thank you for your answer. As far as I understand for each organisation I have to deployed two connection profiles, one for deploying and one for transaction. What is the difference between the two connection profiles and how can I deploy a business network for deploying a consortium of multiple organisations ?

[ ](https://chat.hyperledger.org/channel/composer?msg=2YS2LyBTzcXYPs3uP) @mahoney1 thank you.. sorry, It takes time for me to understand.. I have two questions. 1. Does the organization in crypto-config.yaml refer to a set of peers or orderers that belongs to a channel? 2. is The unit of the MSP (Membership Service Provider) an Organization or a Participant?

seungchan (Fri, 14 Jul 2017 09:16:21 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=2YS2LyBTzcXYPs3uP) @mahoney1 thank you.. sorry, It takes time for me to understand.. I have three questions. 1. I have seen that Composer provides transaction definitions and transaction processor functions. What is different from the chain code? 2. Does the organization in crypto-config.yaml refer to a set of peers or orderers that belong to a channel? 3. Is the unit of the MSP an Organization or a Participant?

davidkel (Fri, 14 Jul 2017 09:21:16 GMT):
@ThomasBouquet basically each organisation will need to get the business network onto their peers so each organisation will have a connection profile (containing their peers) to do this. Then each organisation will have their own connection profile to submit transactions to peers across organisations depending on their defined endorsement policy (that connection profile will have the peers to submit transactions to)

ThomasBouquet (Fri, 14 Jul 2017 09:31:14 GMT):
@davidkel Ok and to deploy the business network I only write : user@ubuntu $ composer network deploy -a my-network.bna -p connection1 -i PeerAdmin -s adminpw

ThomasBouquet (Fri, 14 Jul 2017 09:31:23 GMT):
For each organisation ?

elrond (Fri, 14 Jul 2017 09:37:16 GMT):
is it possible in the subscribing to events in the composer e.g "businessNetworkConnection.on('event', (event) => { // event: { "$class": "org.namespace.BasicEvent", "eventId": "0000-0000-0000-000000#0" } console.log(event); });" is the example in the documentation. is it possible to make another peer listen to events from another peer in the network? say peer on executes a function in which it emits an event called "specialEvent", could for instance peer2 subscribe to listening to the "specialEvent" and based on such, execute or do something else?

davidkel (Fri, 14 Jul 2017 09:38:51 GMT):
@ThomasBouquet It will be something like that, but in the real would a person from 1 organisation won't be deploying to another organisation's environment. If you are trying to do it yourself say in a test environment then it is going to be a lot more complex due to security around who can put chaincode onto a peer and trying to manage this from a single machine. PeerAdmin isn't a userid, it is purely a label referencing cryptographic material you have imported into your keyValStore of your connection profile which has meaning to a single Peer or set of Peers within the same organisation, depending of course on how you have defined you fabric topology. I would highly recommend understanding a fabric topology first by reviewing the hyperledger fabric documentation and getting help on the other fabric channels

ThomasBouquet (Fri, 14 Jul 2017 09:41:32 GMT):

mahoney1 (Fri, 14 Jul 2017 10:07:01 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=EMQXEzyEZd5J5ECqu) @elrond So, when transactions call the `emit` function to emit an event, the events are not emitted immediately, instead, the events are added into the output of the transaction ; the transaction then gets added into a block and committed. When a peer receives a new committed block, it emits all of the events in that block to all connected clients. *All* peers in a defined channel receive all the new blocks - so - all peers get all the events. Hope this helps.

[ ](https://chat.hyperledger.org/channel/composer?msg=qv9YTxZoeoci2rzBN) @VinodPai I resent your .bna network file back to you - you need to look at a number of things including relationships to be defined, but at least you can see from the sample I sent - and you can submit transactions. The Modeling language is here - https://hyperledger.github.io/composer/reference/cto_language.html. A fundamental problem in your Transaction Processor was the transaction identifier being passed. cheers

I'm struggling on importing a namespace from one model file to another. For example, I have A, that has a transaction that involves a field from B. I have A.cto and B.cto in the same models directory, but I cannot simply import org.B into org.A. Any advice on how to proceed? I've tried googling around and I haven't found anything, and the documentation only stated that you can import.

@trygvevang remove any previously imported Peer admin certificates from your keyValStore directory defined in your connection profile, then use `composer identity import` to import each peers admin certificate (if they are different) into your keyValStore. Then you can deploy to each peer as required using appropriate identities you have imported that have admin rights on the peers.

@dstarina that install process installs a fabric development server and playground as a docker image, then starts containers of those images up. It doesn't affect composer-cli for example. So if you are running `composer -v` to determine the version then it won't change that

@ThomasBouquet If your fabric uses TLS then you will need to provide the appropriate certificate information. Whoever sets up the fabric will provide those certificates

davidkel (Mon, 17 Jul 2017 09:42:24 GMT):
@ThomasBouquet composer identity import should be used to import peer and channel admin crypto material into your profile keyValStore so that you are able to deploy business networks. Again whoever set up your fabric should provide that information to you. At the moment we can only support deploy where Peer Admins are also channel admins, but we are looking to being able to support environments where this isn't the case in the very near future.

[ ](https://chat.hyperledger.org/channel/composer?msg=G3s8K8uwkjxhNPWkE) @ThomasBouquet "Failed to load connector module composer-connector-hlfv1" is usually an install issue. Can you confirm your npm / node / versions , that you did the install as non-root and using a supported OS version. The supported versions are as shown under 'Before you Begin" section @ https://hyperledger.github.io/composer/installing/development-tools.html . Next step would be to run `npm uninstall -g composer-cli` followed by `npm install -g composer-cli` and ensure you have the corresponding latest Hyperledger Fabric v1.0 GA docker images (suggest to remove earlier 'beta' images and containers if they exist to avoid confusion, using docker rmi command for images fyi) - and check that there are no install issues./

You should also need to uninstall any other composer modules that were previously installed here -> https://hyperledger.github.io/composer/installing/development-tools.html and install them again once npm v3.10.5 is in place.

Hi, regarding Yeoman. I had two transactions for which ` yo hyperledger-composer ` created two folders. Later I deleted one of the transactions, but ` yo hyperledger-composer ` didn't remove it from the app folder and throw error on ' npm run '. I manually deleted the folder for 2nd transaction and it worked well. Is there a better to remove ng2 files for the transaction no longer needed?

When the ng2 app is generated, asset variable names are displayed as table headings. E.g. String networkID or enum OPTION1. Is there a way by which the heading be displayed as *Network ID* or *Option 1* ... How to handle the casing and spacing?

[ ](https://chat.hyperledger.org/channel/composer?msg=cMwrAiFRRxS8sNZq7) @coder-ajay please refer to the tutorial links or check out the {asset} subdirectory your generated NG2 app has created - eg. under /src/app - where an HTML is generated with elements etc etc. The rest of your question on spacing related to CSS styling most likely - the generator only creates a default file for you (understandably, its a skeleton app)..

theophoric (Mon, 17 Jul 2017 16:30:02 GMT):
I'm getting back into a project after a few weeks -- getting this error when building the archive file: `IllegalModelException: Transaction should not specify an identifying field`. Docs and vscode extension still specify or expect transactions types to have an "identified by" statement

theophoric (Mon, 17 Jul 2017 16:30:23 GMT):
e.g. ``` transaction IssueTokens identified by transactionID { o String transactionID // this can be tied to a gateway transaction o Long amount // # of tokens } ```

ansonlau3 (Mon, 17 Jul 2017 16:36:47 GMT):
@mahoney1 just confirmation world state db means Ledger ?

davidkel (Mon, 17 Jul 2017 16:39:52 GMT):
@ansonlau3 The world state DB is an upto date view on the current state of the ledger.

@davidkel thanks :pray:

@theophoric what level of the vscode extension do you have ? Could you post where the docs still show transactions using identified by ?

@theophoric no, you don't need to explicitly import it, not unless something has changed between 0.9.1 and 0.9.2. Do you get the same problem if you try the online playground ?

No -- works fine with online version

On the development guide is said to ```curl -O https://raw.githubusercontent.com/hyperledger/composer-sample-applications/master/packages/getting-started/scripts/prereqs-ubuntu.sh``` I'm getting file not found from this command

@raheelz Transactions are atomic by definition. Unless everything goes perfectly, the read/write set that is generated during endorsement never gets committed and everything you did was effectively rolled back.

Update -- I'm running composer v0.9.2 and running Safari Version 10.1.1 (12603.2.4) -- if I run in 'private browsing mode' I get the errors described above / earlier. However if I launch http://localhost:8080/editor in "regular" or non-private mode, it appears to run correctly, e.g. when composer.sh launches localhost editor in non-private mode it immediately brings up basic-sample-network 0.1.0 and will successfully deploy the car auction network, for example.

CT123 (Mon, 17 Jul 2017 20:12:42 GMT):
Net-net documentation needs to reflect that for users running against Safari they must be in non-private broswing mode for a local composer implementation to run correctly

CT123 (Mon, 17 Jul 2017 21:36:14 GMT):
@sstone1 - thanks will add a note to git -- if memory serves believe @davidkel mentioned a while back that running in Chrome (may have been firefox) in 'incognito' mode seemed to work for him so perhaps this is a Safari issue? Will add the notes anyway - thanks

davidkel (Mon, 17 Jul 2017 21:37:37 GMT):
@CT123 it is a safari restriction (and probably firefox as well)

@bart.cant@gmail.com you get this message because playground remembers your last identity you were using. Unfortunately the last identity you used isn't PeerAdmin and so doesn't have authority to get the list of instantiated chaincodes. If playground lets you, you need to switch identities to PeerAdmin or you have going to have to clear local storage.

@baoyangc that error implies that the fabric-client node module dependency hasn't installed correctly. Suggest you uninstall composer-cli and re-install it

davidkel (Tue, 18 Jul 2017 08:25:00 GMT):
@baoyangc something must have changed somewhere in your setup. The only time I have seen this error is if the following line in the fabric-client EventHub.js file hasn't worked. ``` var _events = grpc.load(__dirname + '/protos/peer/events.proto').protos; ``` fabric-client is a dependency for composer-cli which would have been pulled down when you installed the cli

[ ](https://chat.hyperledger.org/channel/composer?msg=MyKdSvyDG5C6wJG7d) @biksen no - your reasoning is fine. It is not mandatory no - docker is used where you have docker containers 'stood up' :-) So your Composer connection profile defined in Playground would connect to a 'remote' Fabric, but the error you are seeing is related to a problem with your environment (in the sense that Composer did not installed properly (so that particular module did not build properly) - can you provide your composer -v output - also npm -v, node -v versions and also `docker ps -a`.. Difficult to know without this information but it points to an install issue if that module is not loading

I execute `composer network deploy ` on org4, and success

baoyangc (Tue, 18 Jul 2017 10:54:02 GMT):
when I execute that on other orgs. It failed

davidkel (Tue, 18 Jul 2017 10:55:57 GMT):
@baoyangc that's correct about deploy, although it should check to see if the chaincode is already instantiated on the channel and not attempt to instantiate again. You can check the file system of peer2 to see if the chaincode has been installed, but if you have got as far as instantiation then deploy assumes it either installed or was installed already. Can you try sending a request to peer2 to see if the chaincode container starts

baoyangc (Tue, 18 Jul 2017 10:57:09 GMT):
yes, in peer2,and peer0, the chaincode is instantiated

baoyangc (Tue, 18 Jul 2017 10:59:18 GMT):
sorry , in peer2, it's not instantiated

baoyangc (Tue, 18 Jul 2017 11:00:52 GMT):
you mean i shoud make an transaction

baoyangc (Tue, 18 Jul 2017 11:01:05 GMT):
i see.

davidkel (Tue, 18 Jul 2017 11:01:31 GMT):
@baoyangc if you send a request specifically to peer2 does it start the chaincode container ? This is a feature of hyperledger fabric in that it only starts the container when required.

baoyangc (Tue, 18 Jul 2017 11:02:28 GMT):
how to make that?

baoyangc (Tue, 18 Jul 2017 11:03:34 GMT):
with Fabric node SDK?

baoyangc (Tue, 18 Jul 2017 11:03:59 GMT):
or to call RestAPI of composer-rest-server?

davidkel (Tue, 18 Jul 2017 11:04:52 GMT):
@baoyangc you could create an asset or run a transaction. The composer command line has ways to do it or you could use composer-rest-server

baoyangc (Tue, 18 Jul 2017 11:04:55 GMT):
I think i shoud instantiate chaincode with peer chaincode instantatied in the `cli` container

davidkel (Tue, 18 Jul 2017 11:05:34 GMT):
@baoyangc You only need to instantiate once.

davidkel (Tue, 18 Jul 2017 11:05:34 GMT):
@baoyangc You only need to instantiate once. You don't have to instantiate on every peer.

baoyangc (Tue, 18 Jul 2017 11:06:14 GMT):
instantiate chaincode for other orgs, not for this one

davidkel (Tue, 18 Jul 2017 11:06:47 GMT):
@baoyangc instantiate is a channel wide transaction. It only needs to be done once for the channel.

It's a configuration on the peer. it's defined by environment variable for example `CORE_CHAINCODE_EXECUTETIMEOUT=90s` sets the timeout to 90 seconds. The default is 30 seconds. However did the chaincode container start at all ?

@baoyangc note that there is a restriction currently for connection profiles to hlfv1. Although you can add multiple orderers to a connection profile, only the first one will receive the request. This is a limitation of the hyperledger fabric node sdk.

kletkeman (Wed, 19 Jul 2017 03:05:55 GMT):
@sstone1 I was reading Blockchain Explored and something struck me that *might* be an interesting security optimization. It seems to me that not deploying transactions would make sense for any peer that does not have endorsement intent. So exclusive committers would have queries on them and no execution capability. By only deploying transactions to the endorsers, those can be locked up in a bullet proof environment and all other peers can be trusted to be impervious to transaction based attacks on blockchain content. Just curious if such a thing makes any sense given the spread responsibilities for consensus etc?

fabric with composer but with "first network"

caroline-church (Wed, 19 Jul 2017 08:17:47 GMT):
if you follow these instructions it will create you a running fabric and connection profile. If you then download the sample-networks from https://github.com/hyperledger/composer-sample-networks you can then deploy the marbles network which is like the first network but written using composer rather than go code

davidkel (Wed, 19 Jul 2017 08:26:18 GMT):
@ThomasBouquet You will need to modify the byfn docker containers to include starting a fabric-ca yourself. You can see how we do it for our composer fabric development server and how we set the connection profile to use that server and apply that to your changes.

When I create an asset I would like this to be recorded on the blockchain. The creation is not a part of a transaction, how can I record this to the blockchain? I've looked at events in the .cto-file, but it seems to me that events are emited by a transaction, is this correct?

[ ](https://chat.hyperledger.org/channel/composer?msg=W92t79oS7pAy4A7kJ) @wael 1) getCurrentParticipant() - see here for example of getting who the participant is (identity of the caller submitting the txn) -> https://hyperledger.github.io/composer/managing/current-participant.html 2) every participant submitting a txn via transaction processor functions are automatically invoked by the runtime when transactions are submitted to the Fabric peers in essence, subject to endorsement and endorsement policy etc http://hyperledger-fabric.readthedocs.io/en/latest/txflow.html 3) Configuring more peers is a Fabric question ; permissions.acl is a Composer concept and definition ; ACL rules (within the context of the Composer business network definition) determine which users/roles are permitted to create, read, update or delete elements in a business network's domain model. You don't control 'peers' in permissions.acl

@wael we have an issue open to extend the metadata collected by the transaction registry (historian) to capture things like the current participant id.

[ ](https://chat.hyperledger.org/channel/composer?msg=ENPnhDP3NtL5odMWX) @RudiDahle In Composer, the asset is recorded on a connected blockchain, (in this case, Hyperledger Fabric). It is a blockchain transaction, in effect "this asset was created on ddmmyy by xyz". The current state of assets and participants are stored in the blockchain state database https://hyperledger.github.io/composer/introduction/key-concepts.html The definition (of say assets or indeed participants) in a model .CTO file are exactly that : modeled definitions. In Composer, the state of assets and participants in the business network (ie already recorded on the blockchain) can be modified by the processing of business transactions through Transaction Processor functions or business logic. Events emitted 'out ' of' Transaction Processor functions are usually for the purpose of notifying or publishing to external applications, that are looking for or are responsible for taking action based on those 'threads' - ie. if this event happens, I want to do something in my application. - the events are ALSO modeled (ie event definition) . - https://hyperledger.github.io/composer/business-network/publishing-events.html

[ ](https://chat.hyperledger.org/channel/composer?msg=8JzmevfJv5K4ukeuA) @ThomasBouquet assuming you mean file connection.json ? If you've tried to deploy with the -i PeerAdmin parameter - then it sounds like your keyValStore doesn't have the correct PeerAdmin credentials /certificate (assuming you used the Dev setup previously from previous threads). If so (or you haven't imported other IDs), I suggest to clear it from your $HOME/.composer-credentials and having downloaded/extracted the latest fabric-dev-servers.zip to *say) fabric-tools, then (from that tools directory) simply run createComposerProfile.sh (the script will recreate the composer credentials and the composer connection profile together). Then try to deploy again eg ```composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString```

Hi Team! This is the first time I am using hyperledger chat. But an instant Q&A tool like this looks really awesome.

mna2016 (Wed, 19 Jul 2017 11:09:59 GMT):
I have 2 questions 1) I am following a tutorial of hyperledger compower. The screenshot of the browser Ui does not exactly match with the screen I am seeing(I am accesing on a windows 10 laptop). The top status bar does not show the profile icon. Instead it shows "admin" link. How do I change a profile 2) I have a blockchain service residing on IBM bluemix. I would like that blockchain to be used via the hyperledger composer playground. I assume I have to use a profile to connect to IBM bluemix blockchain. I need the sample profile template\file that I can import into hyperledger playground.

[ ](https://chat.hyperledger.org/channel/composer?msg=5MeK5rxYSB5fz37uv) @mna2016 hi there and welcome online :-) on 1) the online playground is for testing / deploying your business network definition - install the local playground to then be able to define a connection profile - eg. to connect to your running Hyperledger Fabric blockchain in Bluemix. 2) Yes. Once you get setup and installed locally, you can check this the answer and description here -> https://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service/ for a definition of the profile for Bluemix. You will need your own unique enrolment ID and enrolment secret to use out on Bluemix ie from the credentials page;

Simplest way to restart is to go to your 'fabric-tools' directory and run ./startFabric,sh - it will stand up new containers. then do a `docker ps -a` to check they are running.

It seems that the docker playground deploys using the identifier `org-acme-biznet` -- I would like to use a different identifier (e.g. `my-composer-app`) so that my client app and the playground can both interact with the same deployment.

@baoyangc if you restarted your ca server, then any admin certificate you previously enrolled probably isn't valid, you should clear out the credentials and re-enroll. If you want credentials to persist across ca restarts then you need to find out more about how to configure the ca server

ScottMorris (Wed, 19 Jul 2017 20:08:04 GMT):
Hi there, I'm trying to figure out how to change the business network that the playground connects too. Is this possible? It kinda looks like it from the composer documentation.

dselman (Wed, 19 Jul 2017 20:40:24 GMT):
@ScottMorris not yet possible, we are working on that right now. Playground is currently hardcoded to connect to org-acme-biznet

dselman (Wed, 19 Jul 2017 20:40:51 GMT):
So, if you name your network org-acme-biznet, then Playground will connect to it

davidkel (Wed, 19 Jul 2017 21:12:28 GMT):
@baoyangc in order to make a request to the fabric-ca you need to use an identity understood by the fabric-ca. 'admin' is an id your configuration has defined as the bootstrap id. However you have an old admin identity and certificate in your keyValStore directory and won't match the one in your fabric-ca because whenever your fabric-ca is restarted it creates a new admin identity with new certificates.

ScottMorris (Wed, 19 Jul 2017 21:16:43 GMT):

germanhs (Thu, 20 Jul 2017 03:17:26 GMT):
baoyangc you use them on the same host?

germanhs (Thu, 20 Jul 2017 03:18:44 GMT):
because when one identity can only be used by one host or with the rest server one user.

baoyangc (Thu, 20 Jul 2017 03:45:21 GMT):
@germanhs did you enable github OAuth?

KevinBai (Thu, 20 Jul 2017 04:22:57 GMT):
how to renew the creds/* keys?

germanhs (Thu, 20 Jul 2017 04:25:24 GMT):
@baoyangc I did try out the github passport yes. You need 1 Identity to start the rest server and 1 identity in your wallet after authentificating. and then you can send as many requests as you want with this Identity but you cant use it in the command line anymore. And the rest server account cant be used by the github account.

germanhs (Thu, 20 Jul 2017 04:26:22 GMT):
What I did is starting 2 Servers on 2 different ports (one running with the admin account secured and one unsecured rest server that uses an Identity from a participant with read only access)

germanhs (Thu, 20 Jul 2017 04:26:59 GMT):
So that everybody can read the data without authentificating but needs to authentificate and add an identity to do something else

baoyangc (Thu, 20 Jul 2017 05:06:48 GMT):
but the admin can do that

davidkel (Thu, 20 Jul 2017 06:02:02 GMT):
@baoyangc issue identity uses the ca server to create the identity crypto material. When communicating with the ca server you have to use an identity associated with crypto material that the ca server recognises. That's why admin works and PeerAdmin doesn't

[ ](https://chat.hyperledger.org/channel/composer?msg=oieAKkC9poQ65cFxM) @KevinBai In Playground? its likely you get this message because playground remembers your last identity you were using. Unfortunately the last identity you used doesn't have authority to get the list of instantiated chaincodes. If playground lets you, you need to switch identities to PeerAdmin or - you have to clear local storage.

It points at composer-cli not installing properly. Did you install as root or non-root ? What is your npm version

ThomasBouquet (Thu, 20 Jul 2017 14:08:13 GMT):
@davidkel So I read line by line the file ca.example.com-cert.pem and add it to connection.json

davidkel (Thu, 20 Jul 2017 14:09:18 GMT):
@ThomasBouquet as you are putting the embedded cert into a json document, the cert MUST contain escaped newline definitions. The PEM specification requires that each line in the pem file not exceed a certain number of characters, so by not including the new lines the pem text isn't valid

ThomasBouquet (Thu, 20 Jul 2017 14:11:09 GMT):
So I need to include /n right ?

davidkel (Thu, 20 Jul 2017 14:11:27 GMT):

@davidkel I can't, I have created a script wich ask the user, how many organisations he wants and after for each organisation, how many peers he want. My script needs to fill automatically the connection profile

[ ](https://chat.hyperledger.org/channel/composer?msg=XyWg99ePkoKcRkCoh) @wael hi, we've just released version 0.10.0 and looks like you've installed the latest Composer version ; if so, then your business network definition needs to be deployed to be compatible with your current runtime - suggest to stop and docker rm ie the 'old' network (eg this is a dev setup). then using composer network deploy command, deploy your business network definition ( .bna file ) using your existing credentials pertaining to your runtime Fabric.

mahoney1 (Thu, 20 Jul 2017 14:36:45 GMT):

@elrond, just seen your previous trace post ; have you done an `npm install` ? - missing node modules suggests you haven't done this..

silliman (Thu, 20 Jul 2017 14:49:22 GMT):
my understanding was the *composer-sample-applications* GitHub repo was updated to support Composer 0.10.0. I just now cloned this repo and have observed that in the *package.json* file for *packages/digitalproperty-app* it is calling for ^0.9.0-0 as a dependency for the composer-* packages. Should I infer that *digitalproperty-app* was not updated to be compatible with Composer 0.10.0 or was this just an oversight in not updating the *package.json* for it?

elrond (Thu, 20 Jul 2017 15:03:56 GMT):

corazza (Thu, 20 Jul 2017 15:13:01 GMT):
anyway, regarding the issue @elrond asked about (cc @mahoney1): the steps to resolve it were: 1. `rm -rf node_modules` 2. revert `package.json`--there were some unexpected external changes to that file by some other node module (specific versions for dependencies instead of `latest`) 3. `npm install` Then, the tests and so on worked as well.

silliman (Thu, 20 Jul 2017 15:42:28 GMT):
@mahoney1 e.g. I did a global install of composer-cli and composer --version returns 0.10.0 for all the components but then after doing npm install in *digitalproperty-apps* it does a composer --version as part of postinall and then it returns v0.9.2 for all of the components

mbwhite (Thu, 20 Jul 2017 15:44:02 GMT):
@silliman it's probably worth clearing out the `node_modules` directory in the digitalproperty-app = if there's an old copy of the composer modules there then NPM won't update them.. IF they still match the version specified

silliman (Thu, 20 Jul 2017 15:45:39 GMT):
@mbwhite this was from a fresh system... I think the problem is that this is in package.json "composer-cli":"^0.9.0-0", "composer-client":"^0.9.0-0",

mbwhite (Thu, 20 Jul 2017 15:48:00 GMT):
that wouldn't be working they way I would have expected those numbers to be resolved.

mbwhite (Thu, 20 Jul 2017 15:48:12 GMT):
I've fresh Ubuntu vm here .. just trying it

mbwhite (Thu, 20 Jul 2017 15:51:03 GMT):
you're right... is installed 0.9.2..

baoyangc (Thu, 20 Jul 2017 15:51:25 GMT):
why this release is 0.10.0? when will be 0.11.0 or 1.0.0?

silliman (Thu, 20 Jul 2017 15:54:23 GMT):
@mbwhite I know I could just try taking those two dependencies out and see if it plays well with 0.10.0, I was just being lazy and thought I'd ask here first if 0.9.0-0 was left in their for a specific reason :-)

mbwhite (Thu, 20 Jul 2017 15:55:06 GMT):
@silliman no - it was based on the faulty assumption that the ^0.9.0-0 would select the 0.10.0 version...

mbwhite (Thu, 20 Jul 2017 15:55:38 GMT):
@baoyangc due to the nature of the changes it required the jump.

silliman (Thu, 20 Jul 2017 15:55:58 GMT):
i believe it will change up to the most right-most non-zero digit with the ^ (not 100% sure)

silliman (Thu, 20 Jul 2017 15:56:17 GMT):
so sounds like I could take those two out and let 'er rip against 0.10.0 then

baoyangc (Thu, 20 Jul 2017 15:57:21 GMT):
before v1.0.0, you don't make sure there is no break changes?

sstone1 (Thu, 20 Jul 2017 16:10:01 GMT):
@baoyangc we are following the rules for semantic versioning - when we make breaking changes we have to increase the middle version.

sstone1 (Thu, 20 Jul 2017 16:10:46 GMT):
and we will keep following those rules - so when we publish a v1.0.0 we will only publish compatible changes in v1.x.y

dselman (Thu, 20 Jul 2017 17:03:43 GMT):
You can use emit to return information to the caller

dselman (Thu, 20 Jul 2017 17:04:20 GMT):
No, you cannot require npm modules (TP functions are executed in a non-Node.js environment). We are working with the Fabric team on support for native Node.js execution.

@mahoney1 @dselman I am wondering if the historian in Fabric v1 will be exposed through the composer REST server, or is there a separate historian being worked on? I've found this confusing in the past. (Note: from what I heard on our interlock today, the historian is complete and exposed through the SDK. The functionality sounds quite complete -- list of assey key states with txid, read tx and get r/w set, etc.)

In composer developer sample, what should we use for the userid and password

https://hyperledger.github.io/composer/tutorials/developer-guide.html

gauthampamu (Thu, 20 Jul 2017 17:42:10 GMT):
So far, we've created our business network definition, written a unit test and interactively tested the solution in the Playground. Now it is time to deploy to a real blockchain! We are going to deploy the BNA (suffix .bna) file to Hyperledger Fabric v1.0; this blockchain environment was set up earlier in this guide. Switch to the terminal, change directory to the dist folder containing the my-network.bna file and type: Copy cd dist composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString

gauthampamu (Thu, 20 Jul 2017 17:42:34 GMT):
Instructions suggest PeerAdmin and password is randomString ? Is this correct...

mahoney1 (Thu, 20 Jul 2017 17:46:13 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=Q8kivvdG2LKHAJPF8) @gauthampamu yes, correct, its random. PeerAdmin isn't a userid, it is purely a label referencing cryptographic material you have imported into your keyValStore defined in your connection profile (as part of the Dev tutorial set up that is).

gauthampamu (Thu, 20 Jul 2017 17:47:22 GMT):
Which script imports into the keystore...

gauthampamu (Thu, 20 Jul 2017 17:47:29 GMT):
the command composer network deploy or curl -sSL https://hyperledger.github.io/composer/install-hlfv1.sh | bash

@davidkel Can you explain what this script actually does install-hlfv1.sh. There is payload in the script, what the purpose of the payload. Also I see that there is creds folder with three files in composer, how is this file generated in this sample. Is it generated using a nodejs application and you just packaged the files created by the nodejs application when store the credentials. ~/composer-data/fabric-dev-servers/fabric-scripts/hlfv1/composer/creds

ScottMorris (Thu, 20 Jul 2017 21:55:16 GMT):
I'm looking at deploying a bna onto one of the sample networks created in the hyperledger fabric samples. based on the discussions that are above, i think I need to setup the composer to deploy the bna. I'm not sure how to get the credentials for the users in the sample network to deploy with once i've setup the composer. Do i have to generate new credentials or do they live on the peers? thx

dwakeman (Thu, 20 Jul 2017 22:09:10 GMT):
I have made some changes to my business network that were significant enough that I decided to use `composer network undeploy` to remove it, then `composer network deploy` to redeploy it. That succeeds, but now my composer-rest-server fails with this error: ```Connection fails: Error: error trying to ping. Error: error trying to query chaincode. Error: chaincode error (status: 500, message: Error: The business network has been undeployed)``` I restarted my composer-rest-server after I did the redploy. Am I not allowed to redeploy a network with the same name? I did it in this case to get rid of some assets that had bad values in them and there were too many of them to do it one at a time with the rest api.

dwakeman (Thu, 20 Jul 2017 22:16:46 GMT):
Never mind. I see a post from a couple of weeks ago stating that Fabric does not yet support this scenario.

baoyangc (Fri, 21 Jul 2017 05:34:40 GMT):
I did that followed the guid `https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html`

davidkel (Fri, 21 Jul 2017 05:35:26 GMT):
@ScottMorris I would first recommend using v0.10.0 of composer as we now support an install/start mechanism which is the new way to deploying composer onto a fabric. You will need to use the `composer identity import` command to import each different peer admin user (and the directory you posted is where you get the admin user for org1) into a composer keyValStore directory. Most fabric examples I have seen make all admins of peers channel admins as well, but if they didn't you would need to import that as well. Once done you would install the runtime on each endorsing peer using `composer runtime install` then you would start a business network using the `composer network start` command. These commands are documented on our website.

davidkel (Fri, 21 Jul 2017 05:51:37 GMT):
@baoyangc when you ran the composer ping command it will look for the identity chai22 in your keyValStore. If it isn't there, it then contacts the CA Server to enroll that user and retrieve the crypto material for that user and store it in the keyValStore as the identity chai22. The error returned is from the CA Server saying that chai22 isn't known to the user or the secret specified is not correct. If you killed your CA Server container and started a new one then you will have lost any issued identities

baoyangc (Fri, 21 Jul 2017 05:53:15 GMT):
really? how about `GET /system/ping`

baoyangc (Fri, 21 Jul 2017 05:54:23 GMT):

davidkel (Fri, 21 Jul 2017 06:00:19 GMT):
@baoyangc the CA server either has no identity defined called chai22 or the secret is wrong

davidkel (Fri, 21 Jul 2017 06:07:14 GMT):
@baoyangc so as you see from the above, the CA server knew about `chai`.

baoyangc (Fri, 21 Jul 2017 06:07:44 GMT):
why not registered?

baoyangc (Fri, 21 Jul 2017 06:08:32 GMT):
would i need bind an public.key?

baoyangc (Fri, 21 Jul 2017 06:12:21 GMT):
I think that the `composer identity issue ` has register chai to the CA

baoyangc (Fri, 21 Jul 2017 06:12:34 GMT):
so chai should be registered

baoyangc (Fri, 21 Jul 2017 06:13:24 GMT):

as you know, we cann't use genrsa

davidkel (Fri, 21 Jul 2017 06:16:29 GMT):
@baoyangc chai has been enrolled from the ca and it's crypto material will now be in your keyValStore. The problem you are seeing is a response from the new Identity Manager that was released in 0.10.0 and is part of the composer runtime running in the fabric. Not sure why you are getting this error though

baoyangc (Fri, 21 Jul 2017 06:18:29 GMT):
thanks, maybe I should bind the public.key

davidkel (Fri, 21 Jul 2017 06:21:41 GMT):
@baoyangc No I don't think that will help at this point. I assume you have read the release notes about the breaking changes introduced in this release and especially around system ACLs and updated your BNA accordingly ? https://github.com/hyperledger/composer/releases

baoyangc (Fri, 21 Jul 2017 06:23:12 GMT):
must add the `systemACL` into permission.acl?

davidkel (Fri, 21 Jul 2017 06:26:49 GMT):
If you haven't defined any system ACLs then this will be the problem

Hey all, after reading the "installing a developer environment" article, I'm a bit confused as to when I should be using the following scripts: ./downloadFabric.sh ./startFabric.sh ./createComposerProfile.sh ./stopFabric.sh ./teardownFabric.sh At what point in the development process do you run them? The developer tutorial doesn't make any direct comment about these scripts, it just references the developer environment install guide. When going through the developer tutorial, I receive the following error in the "Deploy to the running Hyperledger Fabric" section. The only script I ran beforehand is the ./downloadFabric.sh . (is this error happening because I didn't use the other scripts?)

camdenT (Fri, 21 Jul 2017 07:24:52 GMT):
@dselman so at what point do you need to startFabric and createComposerProfile? right before you want to deploy your bna file? And when would you do a "stop" versus a "teardown"? Does the "1st time on new fabric" mean that you have to run createComposerProfile if you're starting up after a teardown?

Hi. Any way to tell Yeoman which version oh Composer to use? I got an error when creating an angular site with yo (also genereated a new REST api), so I had to install new version of composer. Which was fine, but wouldn't be great for production environment.

mahoney1 (Fri, 21 Jul 2017 07:45:01 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=2keg5LCW9JEQGDZep) @camdenT having 'downloaded' Fabric (you've done that), you run 'startFabric' script - then as a first time user - yes, you run createComposerProfile to create a connection profile (so that you can connect to the Fabric runtime from Composer) and it imports the PeerAdmin certificate. So at that point you can run the Composer network deploy command to deploy the business network definition (.bna file). Teardown only comes once you've need to look to recreate an environment

camdenT (Fri, 21 Jul 2017 08:09:12 GMT):
@mahoney1 If I understand correctly, after the first time, I will really only need to use the start and stop commands? I won't really have a need for teardown?

[ ](https://chat.hyperledger.org/channel/composer?msg=WZgcXQcNyGJD62h97) @ascatox correct - Importing is effectively loading the business network definition (eg model, script files, ACLs) into Playground (eg with a view to modifying/testing/validating it) ; whereas `composer network deploy` is deploying the business network definition to a Hyperledger Fabric runtime (v1.0 for example). This can be from Playground or from an archive file on disk.

[ ](https://chat.hyperledger.org/channel/composer?msg=AenoKDGFJFByCnScQ) @ShobhanaSundararaman right, so its environmental ... Ideally, when you install composer modules globally (eg. composer-cli) you should install using a designated, non-root user. If there are issues (eg, on Ubuntu with permissions to write/update node directories located in system directories like /usr/local or /usr/lib as you wrote of) - the solution is perform the npm install to a *directory you have access to* - rather than resort to root or sudo access, as this is not good practice. Here is what to do to set the npm prefix to a given directory, ... "npm config set prefix /home/myuser/" In this case, global binaries are placed in /home/myuser/bin which is in your PATH, and the modules are placed in /home/myuser/lib ... This is a method to do all the 'global' installs as non-root

Hi is there any composer feature (or roadmap) to query the history DB of Fabric via Composer?

DannyWong (Fri, 21 Jul 2017 16:02:58 GMT):
as i know even the nodeJS SDK seems has not implemented this feature yet (seems only the Go SDK implemented)

DannyWong (Fri, 21 Jul 2017 16:05:10 GMT):
sorry, seems Go SDK also not implemented

dselman (Fri, 21 Jul 2017 16:07:19 GMT):
Which `shim` method are your referring to?

DannyWong (Fri, 21 Jul 2017 16:10:07 GMT):
fabric/core/ledger/kvledger/history/historydb/historyleveldb/historyleveldb_query_executer.go

dselman (Fri, 21 Jul 2017 16:12:37 GMT):
How is that exposed to chaincode? Is it available?

DannyWong (Fri, 21 Jul 2017 16:13:35 GMT):
or chaincode.go `func (stub *ChaincodeStub) GetHistoryForKey(key string) (HistoryQueryIteratorInterface, error) {`

dselman (Fri, 21 Jul 2017 16:13:52 GMT):
Ah, yes -- GetHistoryForKey.

DannyWong (Fri, 21 Jul 2017 16:18:30 GMT):
so... if SDK/Composer can support this (or even add query) on it.... it will be super nice.

DannyWong (Fri, 21 Jul 2017 16:19:15 GMT):
although most of the time we will work with the "state", however, what makes Fabric special is the historyDB that makes the change readable...

dselman (Fri, 21 Jul 2017 16:19:56 GMT):
We've nothing in the immediate plan to expose that via Composer. It would be good to get some use cases to drive it.

dselman (Fri, 21 Jul 2017 16:20:04 GMT):
``` // KeyModification -- QueryResult for history query. Holds a transaction ID, value, // timestamp, and delete marker which resulted from a history query. message KeyModification { string tx_id = 1; bytes value = 2; google.protobuf.Timestamp timestamp = 3; bool is_delete = 4; } ```

dselman (Fri, 21 Jul 2017 16:20:45 GMT):
We'd have to think about how a Composer user wanted to consume that

dselman (Fri, 21 Jul 2017 16:22:40 GMT):
keys in Composer are assets or participants, and you can query the transaction registry (soon to become the Historian)

paul.sitoh (Fri, 21 Jul 2017 16:22:58 GMT):
@DannyWong i think i have seen it in blockdecoder. Travelling now. So can't access. Check there.

paul.sitoh (Fri, 21 Jul 2017 16:23:47 GMT):
Not 100per cent

dselman (Fri, 21 Jul 2017 16:27:21 GMT):
I.e. is it more natural to say "find all transactions that update the state of asset x with conditions a, b, c" or to say "give me all transaction for asset x"

hi guys, one a question

javiercuicapuza (Fri, 21 Jul 2017 16:53:02 GMT):
how yo deploy a bna file in ibm bluemix

javiercuicapuza (Fri, 21 Jul 2017 16:53:10 GMT):
are there a tutorial?

javiercuicapuza (Fri, 21 Jul 2017 16:54:27 GMT):
and how to setting the membership, peer, certificate

anarancio (Fri, 21 Jul 2017 17:01:08 GMT):
@javiercuicapuza first you have to create a profile pointing to your bluemix installation (there is a good response of @sstone1 about each field here: https://stackoverflow.com/questions/42309207/fabric-composer-integration-with-bluemix-blockchain-service)

anarancio (Fri, 21 Jul 2017 17:01:33 GMT):
after you create the profile you can deploy it using the CLI

anarancio (Fri, 21 Jul 2017 17:01:41 GMT):
composer network deploy command

anarancio (Fri, 21 Jul 2017 17:02:20 GMT):
composer network deploy -p -a -i -s

anarancio (Fri, 21 Jul 2017 17:02:47 GMT):
and after some minutes that should deploy your bna on bluemix

javiercuicapuza (Fri, 21 Jul 2017 17:10:50 GMT):
and is possible to execute the following command: composer-rest-server -p hlfv1 -n basic-sample-network -i admin -s adminpw -N never ?

Trying to do a local Composer install on Mac following these instructions: https://hyperledger.github.io/composer/unstable/installing/development-tools.html but this does not result in a running, local composer container. Followed these instructions, https://hyperledger.github.io/composer/unstable/installing/using-playground-locally.html, but can never seem to get a browser connection to the Composer container that results. Anyone done this and documented it?

dselman (Fri, 21 Jul 2017 17:49:17 GMT):
Hey Greg. Any reason you are using the `unstable` docs?

dselman (Fri, 21 Jul 2017 17:49:37 GMT):
Many of the team use/test on Macs. What are you seeing? Got any error messages?

anarancio (Fri, 21 Jul 2017 17:53:07 GMT):
@javiercuicapuza right, after you deploy your bna you should be able to run composer-rest-server but off course you have to do it with the bluemix profile

javiercuicapuza (Fri, 21 Jul 2017 17:56:12 GMT):

@javiercuicapuza Thank you for responding Javier. My goal is to install Composer locally on a Mac. When I follow the instructions to install locally using curl, the process completes successfully and I even see the fabric and composer containers running fine. When I go to connect to localhost:8080, my browser (tried Mozilla and Chrome) cannot find the endpoint.

GregSessions (Fri, 21 Jul 2017 18:23:59 GMT):
@javiercuicapuza what process did you use to install Composer locally?

anarancio (Fri, 21 Jul 2017 18:28:25 GMT):
@GregSessions I used https://hyperledger.github.io/composer/installing/using-playground-locally.html to install composer on my Mac environment

anarancio (Fri, 21 Jul 2017 18:28:38 GMT):
after that I installed the CLI and composer-rest-server

GregSessions (Fri, 21 Jul 2017 18:38:00 GMT):
@javiercuicapuza Thanks Javier. That's what I did. I'll try again and look more carefully for any errors.

Hi Everyone! I'm new to composer. I'm building a business network. I have 2 Assets let's say is A and B, A has an array of relationships to B. I have already created a transaction that affects some properties of B and has some business logic. Now I need to define a transaction that affects A and also has to perform the same operation defined in the first transaction on every B that belongs to that A. My questions are: Is there a way to submit a new instance of the first transaction from the function of the second transaction? If not, what is the best practice to reuse code between transactions. Thanks in advance for your help. Best Regards

GregSessions (Fri, 21 Jul 2017 20:02:53 GMT):
@javiercuicapuza @anarancio Thank you both for helping me. I don't know exactly what the root of the problem was, but I re-installed Docker and all is well. I think I just messed things up during my install. Learning.

JGraft (Sat, 22 Jul 2017 21:39:58 GMT):
Trying to better understand how a user would interface with transaction history. If we had a Car asset and a Purchase transaction, is there meant to be a function that would let a user query the Purchase transactions for a specific car? In the composer-rest-server and the node.js client examples, I saw functions for querying an asset registry and but not the transaction history of that asset?

JunLi_June (Sat, 22 Jul 2017 22:33:05 GMT):
@vandan101 I got similar error. To figured it out, I double checked my composer-cli version and modified the associated data in the package.json file, then it worked, maybe you can try

dselman (Sun, 23 Jul 2017 05:27:41 GMT):
Looks like you need to install Python (used by some npm module for native compilation).

dselman (Sun, 23 Jul 2017 05:29:39 GMT):
@JGraft we are working on expanding the transaction registry to capture more metadata, including the assets that are updated, created, modified during transaction processing. We are calling this the Historian. https://github.com/hyperledger/composer/issues?q=is%3Aissue+is%3Aopen+historian+label%3Ahistorian

dselman (Sun, 23 Jul 2017 05:30:46 GMT):
Until the Historian comes online what you can do is add a collection of transactions to your asset model. When a transaction is processed that updates an asset you store the transaction in the asset.

dselman (Sun, 23 Jul 2017 05:32:04 GMT):

I have been using the trade-network example and made a few changes to it. I've added multiple types of participants, and several types of assets. I set up the participants like this: ``` abstract participant Actor identified by aId { o String aId o String name } participant Supervisor extends Actor { } participant Worker extends Actor { } ``` But when I try to do a transaction of an asset from one participant to another I get this error: ``` "error trying invoke chaincode. Error: chaincode error (status: 500, message: Error: Object with ID 'Participant:org.acme.move.Actor' in collection with ID '$sysregistries' does not exist)" ``` Why is it trying to look for an Actor when this doesn't even exist in the database? And how may I best solve this?

@baoyangc what version of the composer-rest-server do you have installed? `npm ls -g --depth=0` should tell you

RudiDahle (Mon, 24 Jul 2017 06:35:01 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=hqWz6EjuuYjp64gDX) @huizar_mx By TP function are you refering to the transaction logic? If so, here it is: ``` * @param {org.acme.move.Transfer} transfer - the transfer to be processed * @transaction */ function transferCase(transfer) { transfer.case.owner = transfer.newOwner; return getAssetRegistry('org.acme.move.Case') .then(function (assetRegistry) { return assetRegistry.update(transfer.case); }); ```

baoyangc (Mon, 24 Jul 2017 06:37:13 GMT):

sstone1 (Mon, 24 Jul 2017 06:38:30 GMT):
is that all the output from npm? i would have expected to see a `composer-rest-server` entry without the `├── ` bit at the front

sstone1 (Mon, 24 Jul 2017 06:39:09 GMT):
in any case, that looks wrong - you should have `0.10.0` of everything

Hi, everyone! I am having trouble running .bna file developed a week ago on Composer online playground. Specifically, it's throwing an error that Identity does not have access to one of the example networks when I am switching to a different user. Last week I did not not have such a problem. Has there been an update to Online Composer Playground? What should I do to fix the problem? Any help is appreciated.

geoms (Mon, 24 Jul 2017 06:41:34 GMT):
Hi, I am trying to use the *Events* from composer. I am able to generate the events. How to consume the events in an Angular based web app ? It seems only NodeJS app can consume the events.

sstone1 (Mon, 24 Jul 2017 06:45:31 GMT):
@baoyangc I suspect if you look in `/usr/local/lib/node_modules/composer-cli/node_modules` you will find `0.10.0` versions of all those modules

sstone1 (Mon, 24 Jul 2017 06:45:48 GMT):
the `npm ls -g --depth=0` command should only show things that you have explicitly installed using `npm install -g`

sstone1 (Mon, 24 Jul 2017 06:46:34 GMT):
@shidosan please read the release notes, particularly those around breaking changes and system ACLs: https://github.com/hyperledger/composer/releases/tag/v0.10.0

sstone1 (Mon, 24 Jul 2017 06:47:21 GMT):
@geoms the REST server does not currently support event publication, this is a feature we are keen to add: https://github.com/hyperledger/composer/issues/1177

baoyangc (Mon, 24 Jul 2017 06:47:33 GMT):
got it, thanks

sstone1 (Mon, 24 Jul 2017 06:48:19 GMT):
in the mean time you need to use the Node.js client APIs, or use the Node-RED nodes. Node-RED is an open source integration program, and you can use it to receive Composer events and publish them to a WebSocket.

geoms (Mon, 24 Jul 2017 07:08:09 GMT):
@sstone1 Thanks!

dselman (Mon, 24 Jul 2017 07:33:22 GMT):
@RudiDahle most likely explanation is that you are submitting a trade transaction which has a relationship to you abstract Actor type, rather than your concrete Supervisor or Worker.

RudiDahle (Mon, 24 Jul 2017 07:34:55 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=yoHdniaAqgBvwr86m) @dselman I'll look into that, and I'll try to redefine my transaction class and logic. thank you

RudiDahle (Mon, 24 Jul 2017 08:14:42 GMT):
I tried to make the transaction relate to only the worker. But still the same error. Could it be that the Case also has a relationship to the abstract Actor? How should I define this to make it work? ``` abstract participant Actor identified by aId { o String aId o String name } participant Supervisor extends Actor { } participant Worker extends Actor { } ``` And the Case definition: ``` asset Case identified by caseNo { o String caseNo o DateTime timeStamp optional --> Actor owner } ```

sstone1 (Mon, 24 Jul 2017 08:15:57 GMT):
@RudiDahle how did you submit the transaction? using the REST server?

RudiDahle (Mon, 24 Jul 2017 08:16:07 GMT):
Transaction: ``` transaction Transfer { --> Case case --> Worker newOwner } ```

RudiDahle (Mon, 24 Jul 2017 08:16:25 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=SXmR9c2iTCAGfmChx) @sstone1 Yes, I submitted it using the REST server

sstone1 (Mon, 24 Jul 2017 08:16:30 GMT):
please can you provide the JSON request body ?

RudiDahle (Mon, 24 Jul 2017 08:16:46 GMT):
For the transaction?

sstone1 (Mon, 24 Jul 2017 08:16:49 GMT):
yeah

RudiDahle (Mon, 24 Jul 2017 08:18:16 GMT):
``` { "$class": "org.acme.move.Transfer", "case": "1", "newOwner": "002", "transactionId": "", "timestamp": "2017-07-24T08:09:21.862Z" } ```

sstone1 (Mon, 24 Jul 2017 08:26:43 GMT):
`newOwner` needs to be in URI format

sstone1 (Mon, 24 Jul 2017 08:27:04 GMT):
try: `resource:org.acme.move.Supervisor#002`

sstone1 (Mon, 24 Jul 2017 08:27:39 GMT):
@dselman maybe we should ban the old formats at the next semver breaking chance we get? or at least throw errors if you provide just the ID for an abstract type?

pospi (Mon, 24 Jul 2017 09:02:24 GMT):
question: do queries work yet, or am I doing something wrong here: ``` query testQueryByField { description: "Search TestAssets, matching on testField" statement: SELECT net.test.boilerplate.TestAsset WHERE (testField == _$searchString) } ``` As far as I can tell from the source code, `==` should be the correct operator, but the query compiler is giving me `Error: Unrecognised type: object, value: {"type":"AssignmentExpression","operator":"=","left":{"type":"Identifier","name":"value"},"right":{"type":"Identifier","name":"_$searchString"}}`.

pospi (Mon, 24 Jul 2017 09:02:52 GMT):
is the parser still a work in progress or should this be doable?

pospi (Mon, 24 Jul 2017 09:10:44 GMT):
(I'm on Composer 0.9.2 btw)

shidosan (Mon, 24 Jul 2017 09:19:25 GMT):
@sstone1 Thanks! Modified the .bna according to new version and it works now.

sstone1 (Mon, 24 Jul 2017 09:25:50 GMT):
@pospi that should work, though the error you have doesn't match with the query file

sstone1 (Mon, 24 Jul 2017 09:26:05 GMT):
it suggests you have a query like `SELECT x WHERE (value = _$searchString)`

pospi (Mon, 24 Jul 2017 09:55:19 GMT):
oh, yes thats weird. possible caching issue...

geoms (Mon, 24 Jul 2017 10:09:08 GMT):
@sstone1 When I am creating an *EVENT* and emit it during a transaction, it is receiving *twice* in the NodeJS app.

geoms (Mon, 24 Jul 2017 10:09:24 GMT):
How to prevent the duplicate event ?

davidkel (Mon, 24 Jul 2017 10:23:55 GMT):
@geoms a common problem when this happens is that you have registered to listen for the event more than once in your client application.

RudiDahle (Mon, 24 Jul 2017 10:37:30 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=HhcdAgAypdqoJK7XD) @sstone1 This got me a bit closer, thank you. This seems to work when I define the owner in URI format when i create an asset. Then it works fine when I try to transfer from Supervisor to Worker. But when I try to transfer the other way around something goes wrong: ``` "message": "Instance org.acme.move.Transfer#7bb2af93-935b-4b09-a78f-813c15e7f650 has property newOwner with type org.acme.move.Supervisor that is not derived from org.acme.move.Worker" ```

baoyangc (Mon, 24 Jul 2017 11:46:19 GMT):
@sstone1 could composer update endorserpolicy dynamiclly

davidkel (Mon, 24 Jul 2017 11:46:56 GMT):
@baoyangc No we only support defining the endorsement policy at instantiation time

mahoney1 (Mon, 24 Jul 2017 11:47:11 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=BLfKubC9AZm978Ch4) @indira.kalagara Composer was built understanding the importance of continuous integration and robust testing, staging and promotion processes. Create unit and system tests for business network definitions just as you would for your other code. Use your DevOps best practices of choice. As you mentioned Bluemix, here is an article that can help guide you in that context: https://www.ibm.com/devops/method/content/deliver/practice_delivery_pipeline/

baoyangc (Mon, 24 Jul 2017 11:47:16 GMT):
thanks @davidkel

dselman (Mon, 24 Jul 2017 12:20:33 GMT):
@geoms I'd expect each peer to emit an event. Do you have 2 peers? You can use the eventId to dedupe the events on the client side.

theathibm (Mon, 24 Jul 2017 12:32:47 GMT):
I'm using composer 7.4.0 at the moment. The assetRegistry.find() seems a little slow. As a work around we created a RESTful service to couchdb to get results faster for a couple hundred assets. I'm not found of going directly to the couchdb, and it's probably not proper to do so. But the find() method on the AssetRegistry is just to slow. Any thoughts?

dselman (Mon, 24 Jul 2017 12:45:45 GMT):
Upgrade to v0.10.0 and use the Composer Query Language

dselman (Mon, 24 Jul 2017 12:46:08 GMT):
It compiles queries to CouchDB and exposes the queries over REST

theathibm (Mon, 24 Jul 2017 12:58:03 GMT):
@dselman Thanks!

davidkel (Mon, 24 Jul 2017 12:59:43 GMT):
@geoms So you are saying that you get a notification box saying 2 events triggered when you submit your single transaction in bluemix playground ? I've just tried a simple sample on it and it only emits a single event for me. Is it possible your transaction code invokes emit twice ?

@krupabathia out of date version of composer-cli or the module dependencies?

dselman (Mon, 24 Jul 2017 13:31:03 GMT):
@elrond the transaction registry is exposed over REST and in the client JS API

How do I check/correct that.. I cloned the git repository and was following the steps as mentioned in the developer guide?

elrond (Mon, 24 Jul 2017 13:36:27 GMT):
@dselman can the client JS API be used inside a TPF? currently I think I only use it in test code, and in TPFs I use code from composer-common or runtime, not composer-client

elrond (Mon, 24 Jul 2017 13:36:39 GMT):
@dselman which does have a getTransactionRegistry method I believe

dselman (Mon, 24 Jul 2017 13:42:16 GMT):
@elrond you could run a query against the transactions -- I *think* that would work, not tried it however. Alternatively you can associate your transactions with the asset (by modelling a containment relationship). The perisable-network sample does that.

dselman (Mon, 24 Jul 2017 13:42:41 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=7sKz4dWzCkeP7xigN) @dselman Dan, Jim replied to my query this morning that there is no SDK object for history, which makes sense since that is exposed through the stub and is thus available only to the chaincode itself. Were I using my existing IoT contract platform, I would simply tap into the "getHistoryForKey" feature to trace the transactions to the states. I would presume that Composer would do exactly the same thing, although I don't think the history feature is actually documented. What I could find: In the module kv_query_result.proto I found this definition, which is one history state for a key: // KeyModification -- QueryResult for history query. Holds a transaction ID, value, // timestamp, and delete marker which resulted from a history query. message KeyModification { string tx_id = 1; bytes value = 2; google.protobuf.Timestamp timestamp = 3; bool is_delete = 4; } The definition of what is in bytes is not shown, nor is it documented. But of course there is the actual code inside module historyleveldb_query_executor.go, which crawls the modifictions in transaction order, looking for writes to the specific namespace and key. The payload is the actual write: // look for the namespace and key by looping through the transaction's ReadWriteSets for _, nsRWSet := range txRWSet.NsRwSets { if nsRWSet.NameSpace == namespace { // got the correct namespace, now find the key write for _, kvWrite := range nsRWSet.KvRwSet.Writes { if kvWrite.Key == key { return &queryresult.KeyModification{TxId: txID, Value: kvWrite.Value, Timestamp: timestamp, IsDelete: kvWrite.IsDelete}, nil } } // end keys loop return nil, errors.New("Key not found in namespace's writeset") } // end if } //end namespaces loop return nil, errors.New("Namespace not found in transaction's ReadWriteSets") Unfortunately, this appears to be all you get.

Another thing to check would be that the channel you have created has the correct name in the connection profile

davidkel (Mon, 24 Jul 2017 15:17:26 GMT):
@alisonb these are strange errors. You don't need to import any identities if your keyValStore has PeerAdminas it appears you have. How much memory does your VM have ?

[ ](https://chat.hyperledger.org/channel/composer?msg=2ZmaxTCJ7xhcSeRNL) @davidkel Thanks so much!! It was the channel, it started successfully after making the composer `connection.json` channel and the channel the Peer was part of match. I can't believe I didn't verify that piece when I was combing over everythign.

[ ](https://chat.hyperledger.org/channel/composer?msg=hTXG4MpjQrZ8MYcvc) @CT123 as @ScottMorris mentioned, its syntax highlighting. You can always use a local install of Playground (one line installer) see here -> https://hyperledger.github.io/composer/installing/using-playground-locally.html to do what you want (with validation/checking of your network scripts/artifacts such as for your model, js, queries etc). For a dev project perspective, you can use Atom editor for example - there's a syntax plugin here -> https://github.com/hyperledger/composer-atom-plugin

[ ](https://chat.hyperledger.org/channel/composer?msg=PnbBq2SgZMhw36q7S) @alisonb hi Alison, how are you? The errors suggest that the Composer env was built on another [virtual] machine or environment and imported /copied by some method into a Cloud environment. Is this true or was the environment built in a Cloud virtual instance? The error "Module version mismatch" suggests so. 2) Composer should not be installed using sudo (and you won't need to in future) - because it can (in essence) cause problems that yield install issues such as the failure message you added 3) The syntax of the identity import isn't correct and it seems you already have PeerAdmin (only judging by the files you are sourcing) from your identity CLI usage.

mahoney1 (Mon, 24 Jul 2017 16:05:43 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=ePAyMFfRbGKNSmQEQ) @ScottMorris hi Scott - is your business network up and running ? Also (difficult to see from screenshot) did you respond 'Yes' to connect to a running Business Network ? As mentioned earlier (and noted in your output - ' permission denied' ) using sudo can cause problems. Ideally, when you install composer modules globally (eg. composer-cli) you should install using a designated, non-root user (and thereafter you run composer tools as a non-privileged user). If there are issues (eg, such as you're seeing, eg. on Ubuntu with permissions to write/update node directories located in system directories like /usr/local) - the solution is perform the initial composer npm install to a directory you have access to - rather than resort to root or superuser /sudo access, as this is not good practice. Here is what to do to set the npm prefix to a given directory, ... "npm config set prefix /home/myuser/" In this case, global binaries are placed in /home/myuser/bin which is in your PATH, and the modules are placed in /home/myuser/lib

mahoney1 (Mon, 24 Jul 2017 16:12:08 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=FBYRPSCurfXhkjgYf) @arbfay what kind of issues - does your remote server outbound access to WWW to install as non-root user ? How much memory (Gbs) etc etc. Are you using Dockerized Fabric runtime in your remote environment?

[ ](https://chat.hyperledger.org/channel/composer?msg=MjE3JEAtdbTh6Q5Y4) @kvnlee this is a Fabric concept - Composer generally exposes business network related operations/schema (eg. assets, participants, transactions) over REST.

[ ](https://chat.hyperledger.org/channel/composer?msg=64v6XSdahdKwMfdXR) @alisonb could you confirm your npm and node (-v) versions please? Reading about this it could be that 1) usually happens when you install a package (such as composer-cli) using one version of Node, then change to a different version. 2) This can happen when you update or upgrade Node 3) It can also happen if you're trying to run a process as root with a globally installed Node. I would definitely recommend uninstalling composer and re-installing given the 'Node mismatch' and 'failed to load' errors. If you're using NVM, I would (as the non-root user) set your global node version using (eg.) `nvm use 6.11.1`

[ ](https://chat.hyperledger.org/channel/composer?msg=GXNmJ6Lz5MPSMvpv4) @javiercuicapuza hi there - The REST server should be configured with a LoopBack connector that stores data in a highly available data source, such as a NOSQL database. To do this, you would use (and install) a loopback connector for that database. Then your REST server will be able to connect (once the datasource for that DB is configured). The Composer REST server is configured using environment variables, as shown on Docs page https://hyperledger.github.io/composer/integrating/deploying-the-rest-server.html, Once configured and the business network is discovered,and the REST server available on your network, your REST API client / browser can connect to the Composer business network and perform operations as normal.

OK - let's see what I can do

JennFoley (Mon, 24 Jul 2017 20:36:33 GMT):
I figured out my error. Is it worth opening an issue for consistency with npms?

adrianblakey (Mon, 24 Jul 2017 20:55:27 GMT):
Is it essential to run the AUFS storage driver on Linux? Or will overlay suffice - since that's what comes ootb with RHEL.

davidkel (Mon, 24 Jul 2017 21:14:01 GMT):
@adrianblakey That depends I guess, if it works then it would be fine for a development machine.

Hi Team, Is it possible for applying access control for *creation of assets* ?

geoms (Tue, 25 Jul 2017 09:16:06 GMT):
For example, I have defined 3 types of participants in the Model file

geoms (Tue, 25 Jul 2017 09:16:36 GMT):
There is a Super user kind of participant, who should create the asset.

geoms (Tue, 25 Jul 2017 09:16:55 GMT):
Other participant can update the assets.

geoms (Tue, 25 Jul 2017 09:17:31 GMT):
Can we restrict only the super user participant will be able to create an asset ?

mahoney1 (Tue, 25 Jul 2017 09:22:31 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=snBLqLJrNkWvemQcE) @uber.twin yes it should be for straight docker start/stop cycle - ie starts the stopped container(s) from its current state(s) eg in a dev environment. Beyond that, for other environments you might want to consider persistence -> http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html - eg. each channel has their own separate ledger which are stored on each peer on said channel

uber.twin (Tue, 25 Jul 2017 09:28:50 GMT):
@mahoney1 sure, I was wandering if the ```"peer channel create", "peer channel join" , "peer channel update"``` commands need be executed after a docker stop/ start

@mahoney1 supposing the channel was setup after the initial "docker up" and there was no "docker down"

[ ](https://chat.hyperledger.org/channel/composer?msg=MvqjNTXdbak3m7as5) @uber.twin there are many factors to consider eg that the environment stayed the same and I'm purely discussing a Dev setup - and that has a different goal to say an upscale test or production setup (where you wouldn't use docker stop/start in the same context realistically and data persisted elsewhere - that said, the configured peers on restart should rejoin) - I have been able to restart 'work' such as `composer network list` of a previously deployed business network and see registries etc etc. I guess this answers your question (the channel was rejoined by the peer).

@mahoney1 Is it possible for applying access control for *creation of assets* ? For example, I have defined 3 types of participants in the Model file There is a Super user kind of participant, who should create the asset. Other participant can update the assets. Can we restrict only the super user participant will be able to create an asset ?

mahoney1 (Tue, 25 Jul 2017 10:25:40 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=qQQ2WfNd78AK7PRpF) @uber.twin docker-compose up? In this case, the container is instantiated from the docker image specified in your .yml file..anything you add/define/configure channel-wise remains there (but would not if you did a docker-compose down).

akshay111meher (Tue, 25 Jul 2017 10:29:44 GMT):
@dselman is it possible have this kind of scenario in composer.. i have transactions t1-->t2-->t3-->t4-->t5-->t6-->t7-->t8-->t10-->t11 now i want want t6 should not be in chain... what is possible solution? do we need a fork there?

mahoney1 (Tue, 25 Jul 2017 10:40:22 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=gKDvLzJ7RHxPBSuEo) @geoms yes -> https://hyperledger.github.io/composer/reference/acl_language.html you just need to specify the participant type and the operation they can perform ```rule SimpleRule { description: "Description of the ACL rule" participant: "org.example.SampleParticipant" operation: READ, UPDATE resource: "org.example.SampleAsset" action: ALLOW }```

geoms (Tue, 25 Jul 2017 10:43:59 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=zBqeq3uTWP8k3Qhbc) @vinitesh No Composer doesn't currently have any direct way to communicate with other business networks (chaincode containers) as yet. But it is in plan (ie a links feature when implemented will introduce a mechanism for biz network A to call biz network B directly) Presently, business networks can emit events (from Transaction Processors) which can be subscribed to 'externally' by a client application (eg. receive an event from biz network A and use it in a transaction on biz network B)

mahoney1 (Tue, 25 Jul 2017 11:12:25 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=LisjFae85EEESP7ud) @akshay111meher if an app user (or from a connected Playground to runtime v1 Fabric) creates a transaction then deletes - the effects on the blockchain itself are an 'add' txn for original txn followed by the 'delete' txn - eg could be separate blocks (eg. delete happens weeks later?) - and the effect of the delete is merely to update the world state - ie reverse the original txn's update on the World state (eg an asset or participant update) assuming they are in sequence.

sstone1 (Tue, 25 Jul 2017 11:30:24 GMT):
@akshay111meher can you explain what you are trying to do? the ledger is an *immutable* log of transactions, you cannot remove a transaction once it has been committed to the ledger.

mahoney1 (Tue, 25 Jul 2017 11:31:30 GMT):

sstone1 (Tue, 25 Jul 2017 11:32:16 GMT):
@akshay111meher if you have committed a transaction that is a mistake/in error, the standard practice in blockchain is to submit another transaction to rectify the mistake/error.

Hello, In the ACL documentation i found following statement. JavaScript expressions used for the condition of an ACL rule can refer to JavaScript utility functions in a script file.

mahoney1 (Tue, 25 Jul 2017 15:08:03 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=gtNfRDWn4ECM73KdY) @uber.twin would need to see your `composer identity issue` command to know and assuming its linked to a FQ participant in your registry. In general terms - in order to make a request to the fabric-ca you need to use an identity understood by the fabric-ca. Usually (in dev) its using 'admin' which (in the dev setup) is a bootstrap id. However if your fabric CA docker container was cleared/restarted you could have an old admin identity and certificate in your keyValStore directory and thus won't match the one in your fabric-ca because whenever your fabric-ca is restarted it creates a new admin identity with new certificates.

dselman (Tue, 25 Jul 2017 15:08:22 GMT):
@gen_el is that a linting rule that is failing?

dselman (Tue, 25 Jul 2017 15:08:49 GMT):
You can control that with...

gen_el (Tue, 25 Jul 2017 15:08:59 GMT):
I suspect @dselman

dselman (Tue, 25 Jul 2017 15:09:00 GMT):
``` /*eslint-disable no-unused-vars*/ /*eslint-disable no-undef*/ /*eslint-disable no-var*/ ```

gen_el (Tue, 25 Jul 2017 15:09:31 GMT):
Had to confirm that before messing with those rules @dselman

dselman (Tue, 25 Jul 2017 15:09:38 GMT):
Put that at the top of your file

dselman (Tue, 25 Jul 2017 15:10:25 GMT):
Or you can tweak the rules in eslintrc.yml

dselman (Tue, 25 Jul 2017 15:11:18 GMT):
or .eslintignore the files

gen_el (Tue, 25 Jul 2017 15:11:26 GMT):

[ ](https://chat.hyperledger.org/channel/composer?msg=vTE9KmwSdDaSMjbfa) @mahoney1 Yup, that is my issue. I'm starting to think that a command in the yo script runs as a non-privileged user but since I've installed stuff as the privilaged user it doesn't have access. My solution then would be to resetup everything to use npm as me and not as root. ``` fvadmin@ubuntu-hyperledger:~$ npm ls -g --depth=0 /usr/lib ├── composer-cli@0.10.0 ├── composer-rest-server@0.10.0 ├── npm@4.2.0 └── yo@2.0.0 ``` My _npm_ and _NodeJS_ versions are ``` fvadmin@ubuntu-hyperledger:~$ npm -v 4.2.0 fvadmin@ubuntu-hyperledger:~$ node -v v6.11.1 ```

@uber.twin _I'm using the client JS API bizNetworkConnection.issueIdentity() and just before trying to issue the identity, I added the participant, in the same client script so my identity is got to be good, isn't it?_ Yes, I would generally agree :-). You could post your code, but the error suggests that the issuer hasn't got the authority to issue identities... So the identity that connects to the business network (substitute variables below as appropriate) eg. ```this.bizNetworkConnection.connect(this.CONNECTION_PROFILE_NAME, this.businessNetworkIdentifier, participantId, participantPwd) .then((result) => { this.businessNetworkDefinition = result; });``` would need to have the authority to issue identities by the CA (eg. if it wasn't 'admin', 'adminpw' that was supplied). You may already have covered this, that said.

@mahoney1 do we have a way to set instantiate policy for chaincode

davidkel (Tue, 25 Jul 2017 16:17:38 GMT):
@baoyangc No we don't support being able to set instantiate policy

sstone1 (Tue, 25 Jul 2017 16:21:43 GMT):
@davidkel that's set at channel creation time right?

davidkel (Tue, 25 Jul 2017 16:23:11 GMT):
@sstone1 last time I looked I think it was set at chaincode install time, but I haven't gone back to see what/how/if etc this works

dselman (Tue, 25 Jul 2017 16:25:43 GMT):
@akshay111meher that is a Fabric error saying that 2 threads/peers have tried to modify the same key concurrently. Fabric uses a lock-free optimistic concurrency model and will roll back transactions that read/write modified keys

dselman (Tue, 25 Jul 2017 16:26:20 GMT):
Your next question is likely to be how to program to that! ;-)

davidkel (Tue, 25 Jul 2017 16:27:31 GMT):
@sstone1 reading the docs here http://hyperledger-fabric.readthedocs.io/en/latest/chaincode4noah.html?highlight=instantiation%20policy you define the instantiation policy in your chaincode package. Then you would use that package to install onto all the peers, so sort of set at install time but defined in the install package

sstone1 (Tue, 25 Jul 2017 16:29:23 GMT):
ok, so maybe something we could do through a `-o` option

davidkel (Tue, 25 Jul 2017 16:31:09 GMT):
it could be an option on the runtime install, only interesting thing would be if 2 orgs install onto their peers what if they put different instantiation policies ?

dselman (Tue, 25 Jul 2017 16:31:59 GMT):
You need to use CouchDB for Fabric queries

dselman (Tue, 25 Jul 2017 16:32:19 GMT):
It's even in the docs! ;-)

DennisM330 (Tue, 25 Jul 2017 16:33:30 GMT):
@dselman, Is that something I need to configure in Fabric, was using sample scripts in Github - https://github.ibm.com/IBM-Blockchain/ibm-container-service

dselman (Tue, 25 Jul 2017 16:34:00 GMT):
Yes. Take a look at the scripts for the fabric dev server

[ ](https://chat.hyperledger.org/channel/composer?msg=KEfP9d7Yx5qaiQ7JL) @davidkel no idea, which is why i thought it would be a channel creation thing (whos signatures are required to instantiate chaincode on this channel) - it seems very weird to get people to provide it at install time!

DennisM330 (Tue, 25 Jul 2017 16:34:48 GMT):
Ah found it: To enable CouchDB as the state database, configure the /fabric/sampleconfig/core.yaml

@sstone1 It is an odd idea to define it in the package such that each install has to bundle a policy

DennisM330 (Tue, 25 Jul 2017 16:47:42 GMT):
When it is appropriate to perform a composer network start? Still using composer network deploy. Does deploy automatically start the network? Seems it still does

composer network start

I see the difference between deploy and start - main question was if deploy calls the start API, appears it does for now?

@DennisM330 "network deploy" does an install followed by a start, where as "network start" just does the start - and we have a "runtime install" command for the install

sstone1 (Tue, 25 Jul 2017 18:02:38 GMT):
the long term plan is to deprecate the "network deploy" and get everybody using install and start

And where can I find said information?

dselman (Tue, 25 Jul 2017 18:25:27 GMT):
@RudiDahle You can model your asset with a creationDate. You then model a CreateAsset transaction, with the TP function for CreateAsset creating the asset and setting the creationDate. You can then write an ACL rule to prevent the creation of the asset using the CRUD methods -- ensuring the asset is only created by submitting a CreateAsset transaction. In the future you will be able to pull this information from the Historian component we are building.

dselman (Tue, 25 Jul 2017 21:28:14 GMT):

dselman (Tue, 25 Jul 2017 21:40:38 GMT):
"chaincode being launched" means that the peer is starting the docker container for the chaincode I believe

ki0apa (Tue, 25 Jul 2017 21:41:05 GMT):
Do you know how I can fix this?

dselman (Tue, 25 Jul 2017 21:41:44 GMT):
I'd do the easy stuff first -- update to Composer v0.10, and HLF v1.0 GA

ki0apa (Tue, 25 Jul 2017 21:42:28 GMT):
composer-cli v0.10.0 composer-admin v0.10.0 composer-client v0.10.0 composer-common v0.10.0 composer-runtime-hlf v0.10.0 composer-runtime-hlfv1 v0.10.0

I'm already on fabric v0.10, I'll check fabric now

dselman (Tue, 25 Jul 2017 21:43:30 GMT):
Can you create a stack over flow question and we'll move it to there -- that way you can attach logs etc and we won't pollute this chat

dselman (Tue, 25 Jul 2017 21:43:33 GMT):

ki0apa (Tue, 25 Jul 2017 21:43:46 GMT):
Sure

dselman (Tue, 25 Jul 2017 21:44:17 GMT):

ScottMorris (Tue, 25 Jul 2017 22:03:10 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=H4JWQmXRrm2sgwZ3q) @dselman This seems to be the issue, the referenced types it is looking for are in other files, which could be imported in TS using `import` but since that isn't being done the system dies. I guess I can manually add that statement in but that is time consuming each time I do an update to the data model.

ScottMorris (Tue, 25 Jul 2017 22:04:50 GMT):
Basically dependencies between files aren't being resolved in the generation process.

dselman (Tue, 25 Jul 2017 22:10:41 GMT):
The code is here if you want to patch it and submit a PR: https://github.com/hyperledger/composer/blob/master/packages/composer-common/lib/codegen/fromcto/typescript/typescriptvisitor.js

dselman (Tue, 25 Jul 2017 22:10:59 GMT):
Or you move all your types into the same namespace...

dselman (Tue, 25 Jul 2017 22:11:19 GMT):
Can you create an issue please and attach the models required to reproduce?

sstone1 (Tue, 25 Jul 2017 22:13:05 GMT):
^ i hit the same problem earlier trying to generate an app for the vehicle lifecycle demo

ScottMorris (Tue, 25 Jul 2017 22:21:50 GMT):
@dselman I'll look into documenting this and generate the required models. Going over the _js_ code atm.

dselman (Tue, 25 Jul 2017 22:25:51 GMT):

@prmdmshra That error suggests you have used the keyword `const` in your transaction javascript. Unfotunately transaction javascript code is limited to ES5 syntax and so `const` cannot be used.

Also the output of `date -R` from the cmdline - as certs are time sensitive.

[ ](https://chat.hyperledger.org/channel/composer?msg=QQiDQSckWaWbjDrTg) @wael hi there - these are really #fabric questions - and #fabric-consensus questions : Composer is not a 'Fabric' configuration/management tool per se; it just includes a sample Fabric dev runtime setup for getting going quickly with Composer, but it will deploy to any instance of Fabric that you configure, that includes your consensus config (that's supported by Hyperledger Fabric). So suggest to ask on #fabric-consensus - currently Solo, Kafka, in time, SBFT mechanisms https://jira.hyperledger.org/browse/FAB-33

I would suggest to run the `./prereqs-ubuntu.sh` script again - but one thing you mentioned previously you had an issue with - was https (eg curl command for prereq script yesterday) so you would need to monitor the output when you run the prereqs script as a non-root user. You can capture the output to a file using `./prereqs-ubuntu.sh | tee -a out.log to review after (or send to me for review if this second attempt does not work).

[ ](https://chat.hyperledger.org/channel/composer?msg=EbcbsnvkwTNdAr2WS) @mahoney1 My client app is using the admin/ adminpw identity. However, I tried to generate my own multi organizations network from scratch, including the certificates library. I've verified the admin/ adminpw is good, since I could use it to add the participant instances and list them. The bizNetworkConnection.issueIdentity() fails, though maybe the CA log associated with my connection profile could help? ``` 2017-07-26T07:48:16.331855497Z 2017/07/26 07:48:16 [DEBUG] Database (/etc/hyperledger/fabric-ca-server/fabric-ca-server.db) exists 2017-07-26T07:48:16.331866092Z 2017/07/26 07:48:16 [DEBUG] Successfully opened sqlite3 DB 2017-07-26T07:48:16.331875929Z 2017/07/26 07:48:16 [DEBUG] Initializing identity registry 2017-07-26T07:48:16.331885985Z 2017/07/26 07:48:16 [DEBUG] Initialized DB identity registry 2017-07-26T07:48:16.331895834Z 2017/07/26 07:48:16 [INFO] Initialized sqlite3 database at /etc/hyperledger/fabric-ca-server/fabric-ca-server.db 2017-07-26T07:48:16.331906054Z 2017/07/26 07:48:16 [DEBUG] Initializing enrollment signer 2017-07-26T07:48:16.331915661Z 2017/07/26 07:48:16 [DEBUG] validating configuration 2017-07-26T07:48:16.331925163Z 2017/07/26 07:48:16 [DEBUG] validate local profile 2017-07-26T07:48:16.331934701Z 2017/07/26 07:48:16 [DEBUG] profile is valid 2017-07-26T07:48:16.331944113Z 2017/07/26 07:48:16 [DEBUG] validate local profile 2017-07-26T07:48:16.331953588Z 2017/07/26 07:48:16 [DEBUG] profile is valid 2017-07-26T07:48:16.331963094Z 2017/07/26 07:48:16 [DEBUG] CA initialization successful 2017-07-26T07:48:16.331972699Z 2017/07/26 07:48:16 [INFO] Home directory for default CA: /etc/hyperledger/fabric-ca-server 2017-07-26T07:48:16.331981840Z 2017/07/26 07:48:16 [DEBUG] 1 CA instance(s) running on server 2017-07-26T07:48:16.331990867Z 2017/07/26 07:48:16 [INFO] Listening on http://0.0.0.0:7054 2017-07-26T07:50:31.235344751Z 2017/07/26 07:50:31 [DEBUG] Received request 2017-07-26T07:50:31.235381460Z POST /api/v1/register 2017-07-26T07:50:31.235388073Z Authorization: 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.MEUCIQDmLlrrCU1ylaFtYGE0kXmTv04300b8AgpsT6CY7wIa5QIgeMvhVWHonwOXpSg44aaM02BjkKI/jj1SAYF+WWrNK7k= 2017-07-26T07:50:31.235396351Z {"id":"ORG1US33XXX","type":"client","affiliation":"org1","max_enrollments":0,"attrs":[],"caName":"ca.frny.com"} 2017-07-26T07:50:31.235558665Z 2017/07/26 07:50:31 [DEBUG] Directing traffic to CA ca.frny.com 2017-07-26T07:50:31.236587442Z 2017/07/26 07:50:31 [DEBUG] Checking for revocation/expiration of certificate owned by 'admin' 2017-07-26T07:50:31.236597698Z 2017/07/26 07:50:31 [DEBUG] DB: Get certificate by serial (240fc34abaf287001d7b61970429633d3efce27a) and aki (3d2aaa1b91c8329e3ceb86db5cd1e692b13531978d8244283511e935b97b3bc1) 2017-07-26T07:50:31.240195603Z 2017/07/26 07:50:31 [ERROR] No certificates found for provided serial and aki ```

[ ](https://chat.hyperledger.org/channel/composer?msg=vSTxER4TnbedqKe45) @UDeshmukh going back to your original question, there's a distinction between the install steps for Hyperledger Fabric and those for Hyperledger Composer :-) welcome by the way ! :-) -> but they're two separate install streams - Composer creates a simple 'Fabric' development environment as the 'runtime' blockchain to interact with from Hyperledger Composer - to install Hyperledger Composer - follow these steps https://hyperledger.github.io/composer/installing/development-tools.html - for Ubuntu - there is a pre-requisites install script described there . For your Ubuntu Server 16.04 (64 bit) you can find out more here -> https://www.ubuntu.com/download/server and that would be installed inside your virtual machine. Once installed, you can start with installing the Composer environment - on the same page link - it describes how the dockerized, simple Fabric blockchain network can be downloaded and started when you get going with Composer. Hope this helps.

@uber.twin CA Servers are not connected in any way to a running fabric (ie there is no communication between it and peers) They are standalone certificate authorities. I don't know how you have set up your CA Server, however I suspect that it is setup in such as manner that if you stop and start the CA server or remove the container and start a new container from a CA image then the admin cert you may have enrolled previously and stored in your wallet/KeyValStore now isn't recognised as a known identity for your CA Server.

@davidkel You are right, I did restart the CA server meanwhile. I think I had this problem before, thanks again. After I deleted the admin cert and keys it works. I still have this uncertainty regarding the identity requet "affiliation" attribute set to "org1" as my connecting identity does not belong to "org1"

davidkel (Wed, 26 Jul 2017 12:46:40 GMT):
@uber.twin affiliation is a concept specific to the fabric CA Server. I am assuming you have done no configuration of the CA server and are just using the standard command line to bootstrap the admin identity and leave everything else as default. Thus org1 is the default affiliation in the CA Server.

@jorisjh You can have multiple js files in the lib directory. Any function declared in one of those files should be callable from functions in other files. So your transaction function can invoke common functions in the same or other scripts. In the future we hope to see a native node.js chaincode container which would allow require

[ ](https://chat.hyperledger.org/channel/composer?msg=CsJEzEsyCwgxp6GRP) @nippleDonkey at first glance, the ACL looks fine (notwithstanding the odd behaviour reported) - I've seen a similar use for string comparison operator here -> https://github.com/hyperledger/composer/blob/master/packages/composer-common/test/acl/test.acl line 91 `condition: (tx.asset.colour === 'blue')` - but both should work fine in your case.

thanks @mahoney1 do you know if the && operands are acceptable? I can't find documentation to say what is or isn't supported?

`getCurrentParticipant()` returns `null` inside a TPF. I think this is because the test that submitted the transaction didn't specify which participant was submitting it. how do I specify that?

davidkel (Wed, 26 Jul 2017 14:53:52 GMT):
@uber.twin I don't know much about configuring the CA Server but I assume that CLI options would override any other config definition

corazza (Wed, 26 Jul 2017 14:57:39 GMT):
@mahoney1 I think I get what you mean, but for my tests to pass, I need that to be non-null

corazza (Wed, 26 Jul 2017 14:58:04 GMT):
ideally it'd look like `submitTransaction(txn, participant)`

corazza (Wed, 26 Jul 2017 14:58:35 GMT):
but that method has no way of connecting the txn with the participant, which I generate dynamically in the test alongisde the txn

corazza (Wed, 26 Jul 2017 14:59:17 GMT):
if it was a live system I suppose that would be specified by the submitting system or whatever and it would work, but in the testing environment it doesn't

mahoney1 (Wed, 26 Jul 2017 15:15:18 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=57ZocMfAnboLYX5GY) @corazza right - see example here of setting up a trade transaction is set up to submitTransaction() https://hyperledger.github.io/composer/tutorials/developer-guide.html you can add a `participant` property to your transaction and assign it the participant who submitted the transaction. It uses the credentials for the identity you specified when you connect to the business network ie to identify the participant and and set it using `getCurrentParticipant()

corazza (Wed, 26 Jul 2017 15:34:21 GMT):
@mahoney1 Yeah, that's what we previously did, but my logic was that we shouldn't be required to set a `participant` field in the transaction since that would be redundant--all transactions are inherently tied to participants, right?

corazza (Wed, 26 Jul 2017 15:34:46 GMT):
But still, if that's the simpler solution, I'll add like a `self` field and go with that..

corazza (Wed, 26 Jul 2017 15:34:46 GMT):
@dselman yes, I know, but that method doesn't work in a testing environment

dselman (Wed, 26 Jul 2017 15:35:28 GMT):
TP functions can call `getCurrentParticipant()` to retrieve the participant that has submitted a transaction

dselman (Wed, 26 Jul 2017 15:36:58 GMT):
it should

dselman (Wed, 26 Jul 2017 15:37:05 GMT):
we have tests that do that

corazza (Wed, 26 Jul 2017 15:37:09 GMT):
nope. returns `null`

corazza (Wed, 26 Jul 2017 15:37:15 GMT):
can you give me an example?

dselman (Wed, 26 Jul 2017 15:37:22 GMT):
probably because you've not issues the identity in your test

dselman (Wed, 26 Jul 2017 15:37:31 GMT):
e.g. see the test for the pii-network

corazza (Wed, 26 Jul 2017 15:37:34 GMT):
yeah probably, I don't know much about that

I've suddenly run into an issue where couchdb container isn't starting -- everything was working fine a couple days ago using the `https://hyperledger.github.io/composer/install-hlfv1.sh` script. Has anyone run into this or have suggestions ?

dwakeman (Wed, 26 Jul 2017 16:23:54 GMT):
I have a fabric 1.0.0 environment running in containers that are accessible from bluemix. I want to build a cloud foundry app (node.js) to use the node api to connect to my network. I think I know what dependencies to add to my package.json to load the composer libraries, but how do I do the `composer identity import`? I know how to build the connection profile in a directory as part of the deploy pipeline, and I used to just create an empty keystore directory, but that no longer works. I have the certs for my fabric environment but I'm not sure how to do the import. Anybody done this? I searched through the channel but didn't find anything. thx!!

mahoney1 (Wed, 26 Jul 2017 16:27:11 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=vwNnbdXTm8foLwjeR) @gitSrinidhi I can't advise on use of -k option - I did read that article you posted. SSL peer certificate errors usually occur when validation of the trust chain (not the actual certificate) fails. Normally, my first recommendation would be to update the CA bundle on the machine. You need to get the pre-requisites manually (ie by following the script we made available to assist with the pre-reqs install) and see exactly where the problem lies. Have you tried another VM for example or pristine snapshot state? Sorry I can't help with this particular issue further.

davidkel (Wed, 26 Jul 2017 16:42:45 GMT):
@dwakeman composer identity import is used to import crypto-material into your connection profile's keyValStore and assign it label. An example where you would need to do that is to import the crypto material for a Peer administrator so that you can then install the composer runtime onto a peer using the `composer runtime install` command. The command should have an example of it's use at https://hyperledger.github.io/composer/reference/composer.identity.import.html

dwakeman (Wed, 26 Jul 2017 17:01:23 GMT):
right, I've used it successfully locally and in docker images I have built, but I'm not sure how to do that for a cloud foundry app.

davidkel (Wed, 26 Jul 2017 18:21:39 GMT):
@dwakeman It's available on AdminConnection Class Which for some reason doesn't appear in our documentation Doh ``` let adminConnection = cmdUtil.createAdminConnection(); let signerCert; let key; try { signerCert = fs.readFileSync(publicKeyFile).toString(); } catch(error) { return Promise.reject(new Error('Unable to read public key file ' + publicKeyFile + '. ' + error.message)); } try { key = fs.readFileSync(privateKeyFile).toString(); } catch(error) { return Promise.reject(new Error('Unable to read private key file ' + privateKeyFile + '. ' + error.message)); } return adminConnection.importIdentity(connectionProfileName, userId, signerCert, key) .then((result) => { console.log(`An identity was imported with name '${userId}' successfully`); }); ``` from the CLI command

dwakeman (Wed, 26 Jul 2017 18:24:56 GMT):
@davidkel so I can run the app and do that before i make a regular connection? using the admin credentials I assume.

davidkel (Wed, 26 Jul 2017 18:27:06 GMT):
@dwakeman It depends on the credentials you are importing as to what you want to do with that identity. If it is an identity you need to install the composer runtime or start the business network then you need them imported before doing either of those 2 tasks

dwakeman (Wed, 26 Jul 2017 18:28:23 GMT):
it's an identity I can use to subscribe to events emitted by my network. I've been using PeerAdmin locally, but I suppose it could be any identity with the right permissions. Thx for the info!!

jorisjh (Wed, 26 Jul 2017 19:08:42 GMT):

dselman (Wed, 26 Jul 2017 19:16:47 GMT):
you can use the experimental `post` api to do that (see docs)

we don't yet support `HTTP GET`

dselman (Wed, 26 Jul 2017 19:22:27 GMT):
We now use Duktape - much better performance

dselman (Wed, 26 Jul 2017 19:23:10 GMT):
We are working with the Fabric team on native Node.js chaincode execution, which will give us even better performance and open up chaincode to use any npm module

dselman (Wed, 26 Jul 2017 19:23:23 GMT):
That won't hit until Oct/Nov however

dselman (Wed, 26 Jul 2017 19:31:40 GMT):
@jorisjh no, not easily

dselman (Wed, 26 Jul 2017 19:32:14 GMT):
You'll have to use the POST stuff and stick something like Node-RED in front of it to broker a POST into a GET.

Hello, question about `composer identity import`..... I know what it does and I've done it locally on my mac, where I can connect successfully to my fabric. If I want to use composer on a different environment (say an ubuntu vmware image running on my mac), do I have to copy the certs into ubuntu and run `composer identity import` inside the image, or can I just copy the contents of my `keyValStore` directory on my mac into the image?

davidkel (Wed, 26 Jul 2017 21:50:49 GMT):
@dwakeman if it is communicating with the same fabric, then you can copy the contents from one keyValStore to another or if you are feeling adventurous you could share your current keyValStore with between the 2 systems

sstone1 (Wed, 26 Jul 2017 23:12:36 GMT):
@UDeshmukh it looks like you have set up Docker Machine. We don't support that. You need to download Ubuntu and install an Ubuntu VM in Virtual Box, and use Composer inside the Ubuntu VM.

Hey all! I'm trying to use the Yeoman generator to create a skeleton business network; however, I am running into an error when I try to assign the network a name. It is not recognizing the name I give it as valid. Anyone else run into this issue?

On a separate note: In the developer tutorial, why is tradingSymbol used as the unique identifier of Commodity? In the real world, multiple people have assets with the same trading symbol; doesn't that mean the identifier isn't unique?

Hi people,

camdenT (Thu, 27 Jul 2017 09:08:42 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=8KCtoKWZvoYxJSDY9) To be clear, I have been trying to think of a way where you have two commodities with the same trading symbol (not currently possible with the tutorial setup), owned by two separate participants. If one of the participants were to give the entirety of his/her asset to the other participant, instead of the receiving participant having two separate assets with the same symbol, he/she would have one asset with the combined value of the two assets; however, I can't think of a way to properly implement it with the modeling language. Anyone have any ideas? How would you uniquely identify the assets in this scenario?

lucrezia.dm (Thu, 27 Jul 2017 09:08:56 GMT):
When I use Playground of Composer and I choose the example "pii-network" I have the same error for actions "authorize access"and " revoke access" . It's " TypeError: Cannot read property 'getIdentifier' of null " . CAn anyone help me?! Thanks a lot

dselman (Thu, 27 Jul 2017 09:12:32 GMT):
@lucrezia.dm you are using composer-playground.mybluemix.net ?

lucrezia.dm (Thu, 27 Jul 2017 09:13:08 GMT):
@dselman yes!

dselman (Thu, 27 Jul 2017 09:15:50 GMT):
You are probably running it as "admin" which has not been mapped to a participant. You should click "admin" in the header bar to access the Wallet for admin, and then add 2 new participants (alice and bob, for example), add them to your Wallet and then switch between them for testing.

dselman (Thu, 27 Jul 2017 09:16:29 GMT):
The error is coming from the transaction processor function most likely:

dselman (Thu, 27 Jul 2017 09:16:34 GMT):
``` var me = getCurrentParticipant(); console.log('**** AUTH: ' + me.getIdentifier() + ' granting access to ' + authorize.memberId ); ```

dselman (Thu, 27 Jul 2017 09:17:08 GMT):
We should add a check there (or ACL rule) to reject the transaction if it has not been submitted by a certificate that is mapped to a participant.

KevinBai (Thu, 27 Jul 2017 09:27:01 GMT):
@dselman Can I use third sdk in the composer? fabric-sdk-node?

[ ](https://chat.hyperledger.org/channel/composer?msg=F8onv3YDawENjuocM) @UDeshmukh hi there and welcome ! yes you do - and have a minimum of 4Gb or more available for that virtual machine. You can get an Ubuntu Server 16.04 LTS image such as https://www.ubuntu.com/download/server .. Note that Composer will 'stand up' a simple runtime Fabric blockchain environment for you - so your install links for Fabric (where you see Windows references) are not particularly relevant just to stand up a Fabric for developing using Composer. The install guide for Hyperledger Composer (once you've installed your Ubuntu server image inside a VM) is here - https://hyperledger.github.io/composer/installing/development-tools.html - you will note that there it talks about a prereqs-ubuntu.sh script which you can use to install pre-requisites - and further down the page there are instructions for pulling down the dockerized Fabric environment to run inside your Ubuntu VM. I hope this helps.

mahoney1 (Thu, 27 Jul 2017 09:40:20 GMT):
[ ](https://chat.hyperledger.org/channel/composer?msg=FCBHPmMPDrDQaNQx4) @ArnabChatterjee you need to use PeerAdmin not admin : `composer network deploy -l DEBUG -a dist/basic-sample-network.bna -p hlfv1 -i PeerAdmin -s random` . its already imported into your keyValStore and hlfv1 defined in your connection profile.

zupan (Thu, 27 Jul 2017 09:55:17 GMT):
I have a conceptual question. I'm performing async requests to Composer REST and I'm getting message: `'error trying invoke chaincode. Error: Peer has rejected transaction \'552b42fa4d2cfd366ff1b7d01371878f53f7553b44f141187c6db86b75f68906\' with cdoe MVCC_READ_CONFLICT', `. I got the same problem when using node-sdk. What is the reason for that? Shouldn't it be possible to submit multiple transactions asynchronously?

dselman (Thu, 27 Jul 2017 09:59:05 GMT):
@zupan Fabric uses lock-free optimistic concurrency, with rollback in case of dirty read/writes. You need to avoid key collisions as far as possible and may need to write retry logic on the client side.

dselman (Thu, 27 Jul 2017 09:59:19 GMT):
Best to take this up on the #fabric channel

The "new transaction showing up" is a bug that will be fixed in the release today.

dselman (Thu, 27 Jul 2017 12:15:04 GMT):
Not sure what you mean about identities

dselman (Thu, 27 Jul 2017 12:16:46 GMT):
@uber.twin you have to INSTALL the chaincode on all peers, then instantiate once. I'm guessing that the chaincode was not installed on peer2

dselman (Thu, 27 Jul 2017 12:17:11 GMT):
@davidkel probably knows more

Pere-Lluis (Thu, 27 Jul 2017 12:20:15 GMT):
Don't know why but the secret wasn't showing up, tried to deploy from 0 again and worked

davidkel (Thu, 27 Jul 2017 12:20:27 GMT):
@uber.twin @dselman is correct it looks like you haven't installed the composer runtime on that peer. Use the `composer runtime install` command with an appropriate connection profile to install the runtime on that peer.

uber.twin (Thu, 27 Jul 2017 12:33:44 GMT):
@dselman @davidkel I didn't explicitly install the composer runtime on peer1. Bellow is the command I use to deploy the network. Do I need to the the same thing, using -p peer2Profile? ```composer network deploy -p peer1Profile --archiveFile myNetwork.bna --enrollId PeerAdmin --enrollSecret adminpw```

davidkel (Thu, 27 Jul 2017 12:37:01 GMT):
@uber.twin The Fabric way for setting up peers and a channel are to 1) install the chaincode on all the peers 2) instantiate the chaincode. Our deploy command can be used to just install chaincode onto other peers if the chaincode has already been instantiated and it tries to work out what to do. However we want to move away from deploy to an install/start process as it better aligns with what fabric requires. So you could use deploy, but I would recommand using the runtime install command instead

uber.twin (Thu, 27 Jul 2017 12:48:55 GMT):
@davidkel is there a doc section addressing this, similar to the the "deploy" alternative -https://hyperledger.github.io/composer/business-network/bnd-deploy.html I'd like to look at some samples, but it seems the composer-sample-applications/packages/digitalproperty-app is still using the "deploy" style
