Use of Embedded Forms raises an error

langfr · January 16, 2018, 8:54pm

I build a small example for use of embedded forms.
Deployed a simple process and HTML form file through Java API.
mbi_TestNoteborn.html (563 Bytes)
mbi_TestNoteborn.bpmn (2.9 KB)

Both deployments are shown in Cockpit.

grafik

When selecting the Process in Tasklist to start an instance, I get this error:

This is the stacktrace of Wildfly10:

Hi @langfr,

please try to put your HTML form in the folder src/main/webapp/forms of your project and change the formKey to embedded:deployment:forms/mbi_TestNoteborn.html
For more details see: https://docs.camunda.org/manual/latest/user-guide/task-forms/#embedded-task-forms

Hope, it helps?

Cheers
kristin

Hi @kristin,

this does not solve my problem. I do not deploy a war file, I deploy the files individually.

Trying to do something like it is described here:

But not by using the REST-API but the Java-API.

My deploy method look like this:

    @TransactionAttribute( TransactionAttributeType.REQUIRES_NEW )
    public void deploy( final String fileName, final byte[] fileContent, final String tenantId ) throws ProcessEngineException
    {
        if ( CamundaInterface.LOGGER.isDebugEnabled() ) {
            CamundaInterface.LOGGER.debug( fileName + ", " + fileContent + ", " + tenantId );
        }
        DeploymentBuilder deploymentBuilder = this.repositoryService.createDeployment();
        deploymentBuilder.enableDuplicateFiltering( true );
        deploymentBuilder.addInputStream( fileName, new ByteArrayInputStream( fileContent ) );
        deploymentBuilder.source( fileName );
        deploymentBuilder.tenantId( tenantId );
        deploymentBuilder.name( fileName.substring( 0, fileName.lastIndexOf( '.' ) ) );
        Deployment deployment = deploymentBuilder.deploy();

        String processApplication = this.managementService.getProcessApplicationForDeployment( deployment.getId() );
        if ( processApplication == null ) {
            this.managementService.registerProcessApplication( deployment.getId(), this.camundaProcessApplication.getReference() );
        }
        if ( CamundaInterface.LOGGER.isDebugEnabled() ) {
            CamundaInterface.LOGGER.debug( "" );
        }
    }

I already changed, that both deployments get the same name set. But this did not help either.
Probably both files have to be deployed together, with one call only. Not one after the other.
But I do not see how this can be done through the Java-API.

Regards, Frank

Yes, the BPMN and form need to be part of the same deployment.

You can call the #addInputStream method twice on the same deployment builder. Or am I misunderstanding the question?

Cheers,
Thorben

Thorben,

you understood me right.
Adding the form file using #addInputStream did the trick.

One deployment with 2 resources shown in Cockpit:

Process instance can be started using the defined form.

Thanks to all.

Regards, Frank
