Boundary signal event attached to humanTask node within multiple Instance process is failing - Urgent help please.

[arif.mohammed]

Hi,

   I have attached a Boundary Signal Event to a HumanTask node within a multiple process instance node, please find the attachment of process image(approval-process.pdf) and the BPMN file (approval-process.bpmn2)

  Error:  As depicted in the process image If I trigger "Terminate" Event, it is failing at org.jbpm.process.instance.impl.CancelNodeInstanceAction.java in execute method. I have attached debug window image(Debug.png), I have also attached the result of the query "select * from NodeInstanceLog order by log_date;" (TerminateEvent-Snapshot1.png and TerminateEvent-Snapshot2.png) before the event is triggered. As you can see from Debug window the value of nodeInstanceId is -1 and following is the snapshot of exception.

java.lang.RuntimeException: unable to execute Action: null

org.jbpm.workflow.instance.impl.ExtendedNodeInstanceImpl.executeAction(ExtendedNodeInstanceImpl.java:74)

org.jbpm.workflow.instance.impl.ExtendedNodeInstanceImpl.triggerEvent(ExtendedNodeInstanceImpl.java:58)

org.jbpm.workflow.instance.node.CompositeNodeInstance.signalEvent(CompositeNodeInstance.java:228)

org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:362)

Note: As you can see from process image I have defined another boundary event "Terminate2". This event is working fine and the human task node is exiting properly. please check the attachment Terminate2-Event.png

     Any quick help is appreciated.

Is this a bug ? Any one have used this feature ?

[arif.mohammed]

Can anyone please help me regarding this issue. For me It looks like a bug OR Am I doing anything wrong here ?

[swiderski.maciej]

this was indeed a bug in 5.4 as it was not taking into consideration composite node instance such as subprocess. So you actually have two options:

• patch the 5.4 that you use based on the improved version from v6, see here
• remove subprocess for the path that uses boundary events

Thanks Maciej for the help. I tried to apply the above patch but that code is referring kie packages and I can not apply this patch to 5.4 version. since I need this feature heavily in my processes,

I am working to upgrade to version 6. But while upgrading to version 6 I am facing an issue and I have opened a new thread(Spring integration with jBPM6.1.0.Beta2 is failing with message "Transaction is already completed - do not call commit or rollback more than once per transaction") can you please help me to resolve this issue.

[swiderski.maciej]

Arif, you could simply reorganize the imports so they will refer to version 5 api classes instead of version 6. All classes should exists in both versions just in different packages.
