Hi
I have been trying to model my BPMN where in one process instance(of process1) throws a signal event which is being expected by another process instance(of process2) as boudary catch event . Signal communication works fine but further execution fails because of following exception. In context of the following diagram, delegate expression in service task “Mark Sales Return And QC” is not being identified/evaluated on receipt of "Mark Sales Return " boundary signal event.
2016-06-26 12:12:51,456 ERROR [org.camunda.bpm.engine.context] (pool-6-thread-1) ENGINE-16004 Exception while closing command context: Error while evaluating expression: ${myListener}. Cause: null: org.camunda.bpm.engine.ProcessEngineException: Error while evaluating expression: ${myListener}. Cause: null
Is there something i am missing? Please help.
Hi @girish_yadav
Could you give more information to the "Mark Sales Return and QC " service task? Please post the BPMN XML part for this service task.
Cheers,
kristin

Thanks for the process XML. I think, it looks fine so far.
The posted process catchs the signal event “ImmediateSRSignal” and should go further to the service task ‘Mark Sales Return and QC’. But the service task is never executed. It is correct?
The exception in the first post contains that a defined listener could be invoked because the defined expression is not correct. I can’t find the ${myListener} expression in the current process XML. Where it is configured or do you renamed some listener?
Cheers,

yes, correct.

actual listener is “markSalesReturnTaskDelegate”. I quoted dummy name just to phrase my problem scenario.
When I look into the process XML, the “markSalesReturnTaskDelegate” is a delegate and not a listener. Maybe, there is the problem?
Please post the code of the “markSalesReturnTaskDelegate”.
Cheers,

yes it is java delegate.
Problem seems to be instantiation of class specified in the delegate expression.It should work irrespective of “markSalesReturnTaskDelegate” being a listener or a java delegate. In normal task completion it is able to resolve the expression but in case of signal event (which is an asynchronous event) it spawn a new thread and all the activities takes place in this new transaction and it is not able to resolve the expression. Somehow i am not able to crack it.
This means the ‘markSalesReturnTaskDelegate’ is executed when it is not triggered from the signal event!
You could try to reproduce the exception with a simple BPMN process which gets a signal event.
Another approach is to provide a unit test that reproduces the problem? You can use the unit testing template to get started: https://github.com/camunda/camunda-engine-unittest
