Multiplicity Violation Error

[aniketvast]

Hello

I hate giving the entire stackTrace in Topics, however for this one, I had to. Heres what I have done
1> Defined a Custom Workflow model and Process Definition.
2> This works fine from the web client.
3> Now I want to start the workflow based on a rule, so I wrote a tiny JS as recommended in the wiki.

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$ccswfcredential:credential";
workflow.parameters["bpm:assignee"] = person;
workflow.execute(document);‍‍‍‍

4>Although I get the following error when I hit ok (which is supposed to start the workflow)

20:39:27,330 ERROR [node.integrity.IntegrityChecker] Found 1 integrity violation

I downloaded the latest Alfresco Source Code 1046 and created this java script.
var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wf:review";
workflow.parameters["bpm:assignee"] = person;
workflow.execute(document);

As you can see, I am calling the built-in review workflow. It still gives me the same error above.


Any help is appreciated.

Thanks.

This is an unusual error as workflow tasks are not actually stored as nodes in the repository, but as native jbpm tasks in the jbpm database schema, therefore, are not checked by the integrity checker.

So, one cause is that an actual workflowTask node is getting created somewhere.  However, I can't imagine how.

Have you created other custom rules, actions etc which might be applied?  Are you creating a workflowTask node anywhere?
