Hi all,

How can I create circular progress bar/loading indicator like this (see attached file)

Thx in advance.

Hi All,

I would like to have a process to change/update Parner's Information (e,g Name). How can I achieve this?

Thx in advance.

Hi All,

I tried to do multiple transactions and have error below.

Error: Error trying invoke business network with transaction id 87c91cb2cd7e7a232466b20d017ad2c3417e6d87ed7aa8a8bef8a3f934526277. Error: Peer localhost:7051 has rejected transaction '87c91cb2cd7e7a232466b20d017ad2c3417e6d87ed7aa8a8bef8a3f934526277' with code MVCC_READ_CONFLICT

The scenario: when a Member earns Points through Purchase, there are 2 transactions:

• the 1st transaction is Earn Points transaction to update Member data
• the 2nd transaction is update Partner data to have new balance = pointquota - eraned-points

I have added pointquota and balance in Partner model as:
participant Partner identified by id {
o String id
o String name
o Integer pointquota default=1000
o Integer balance
}

Any idea how to fix this? If I simply separate 2 transactions by using GUI (click buttons in html page), the 2 transaction went thought.

Thx in advance.

Hi all,

I followed the instruction to deploy network to Fabric locally as below:

1. Removing all running containers, and all previously created Hyperledger Fabric chaincode images:
   docker kill $(docker ps -q)
   docker rm $(docker ps -aq)
   docker rmi $(docker images dev-* -q)

2. Start fabric and create peer admin card:
   cd fabric-dev-servers/
   ./downloadFabric.sh
   => OK
   ./startFabric.sh
   => )K
   ./createPeerAdminCard.sh
   Error: "v0.19.x is not supported for this level of fabric. Please use version 0.16"...

So I uninstall all v0.19.x and install v0.16.0 by commands:

npm uninstall composer-cli
npm uninstall composer-rest-server
npm uninstall -g generator-hyperledger-composer

Then install version 0.16:

npm install -g [email protected]
npm install -g [email protected]
npm install -g [email protected]

After that, I do step 2 above :
Start fabric and create peer admin card:

cd fabric-dev-servers/
./downloadFabric.sh
=> OK
./startFabric.sh
=> )K
./createPeerAdminCard.sh
=> OK

Then I do next step:
3) Install the business network:

cd ../
composer network install --card PeerAdmin@hlfv1 --archiveFile [email protected]
Error: Incorrect command. Please see the list of commands above, or enter "composer network --help".

Found that my composer version is now v0.16.0, which is not support command "composer network install ...". Only composer version is now v0.19.x onward allows to use command "composer network install ...". Thus I stuck there because if use composer version v0.19.x, there is error in step 2) Start fabric and create peer admin card saying that "v0.19.x is not supported for this level of fabric.", However, if I use version v0.16.0, there is error in step 3) Install the business network saying that this version does not support command "composer network install ...".

Any help?

Thx in advance.

I'm trying to understand the ins and outs of permissions and rules and couldn't figure this one out.
Is there is an issue with this partner rule condition:

//Partners Not to have access to other member accounts
rule PartnerAccessPartner {
description: "Allow memebers to access only their profile"
participant(p): "org.clp.biznet.Partner"
operation: ALL
resource(r): "org.clp.biznet.Partner"
condition: (r.getIdentifier() === p.getIdentifier())
action: DENY
}

I think the condition should be removed from this rule to make it effective - this seems to only block a partner from ALL operations on their own account.

Getting error when executing...
./createPeerAdmin.sh
Using composer-cli at v0.19.4
Typeerror: IdCard is not a constructor
Error: Unable to read file: /tmp/[email protected]
Typeerror: Admin connection is not a constructor

As this example is a great starting point to get started with Hyperledger fabric and IBM blockchain. I would like to develop this application using JavaSDK . is there any available guidance material to get started?

I'm running into an issue when i run the command
npm install
Here is the error I get.

need help.

In the permissions.acl file, there is an error on line 81 and 83 (aliases are present when there is no condition), and that's throwing the following error:

Was fixed by removing the aliases (p for participant and r for resource).

peeradmincard created successfully through command $ ./createPeerAdminCard.sh also i got the following output when run [ $ composer card list ] command

composer card list
The following Business Network Cards are available:

Connection Profile: hlfv1

├─────────────────┼───────────┼──────────────────┤
│ PeerAdmin@hlfv1 │ PeerAdmin │ │
└─────────────────┴───────────┴──────────────────┘
Issue composer card list --card to get details a specific card
Command succeeded

My problem is : when i opened the application at address [ http://localhost:8000/registerMember ] and entered everything like userid ..etc i got the following error [ Card not found: admin@clp-network ]

any advise please ?

I want to generate my own network like customer-loyalty-program, which should generate the same network with nodejs framework plus angularjs component as well. the architecture should be same as this loyalty program.

I couldn't find where to ask this so here it goes:

Is a partner here (a company) the same as a "membership of an organization" in the IBM cloud plans?

Is a member here (a customer redeeming points) the same as a "small peer" in the IBM cloud plans?

What are the limitations?

The application is fully functional if use locally deployed network. When I tried deploying the network to cloud, the members/partners are created with no problem using admin card, however, I'm getting ECONNREFUSED error on logging in as a member/partner.

Here's the error log

I tried following the instruction precisely step-by-step but I'm not sure if I did wrong somewhere or this is how it is written. Thanks!
