    Process can't complete itself

    Vladimir Vinn Newbie

      Hello everyone!

      I'm using JBPm 6.2.0.CR4


      I use custom workitem handlers. In those handlers I delegate an actual workitem processing to a separate thread, and in that thread I call ksession.getWorkItemManager().completeWorkItem().

      I assume that process should be automatically completedm when all workitems are completed. But this does not happen. And I dont have and idea why.

      If I call completeWorkItem in executeWorkItem() method of WorkItemHandler then everything works fine.


      May be you have any ideas?

      Thank you!

          could you provide an more concrete example as that should work assuming completeWorkItem finishes without an error.

            The case is:


            1. Procesess is started

            StatefulKnowledgeSession ksession = (StatefulKnowledgeSession) deploymentService.getDeployedUnit(JBPM_PROCESSES_DEPLOYMENT_ID)
                    ksession.startProcess(processName, params);


            Each workitem is handled by a same type of WorkItemHandler

            2. WorkItemHandler sends a message with neede info plus process instance ID via JMS to a custom event processor

            3. Processor processes the message (does some logic) and sends a similar response via JMS to response handler

            4. This Response handler completes the workitem

            StatefulKnowledgeSession ksession = (StatefulKnowledgeSession) deploymentService.getDeployedUnit(JBPM_PROCESSES_DEPLOYMENT_ID).getRuntimeManager()
                    ksession.getWorkItemManager().completeWorkItem(gateActionResponseMessage.getWorkItemId(), results);

            5. Next workItem is handled in a similar way (pt. 2 - 4)


            After all workitems are completed, i assume the process must complete also. But is does not.

              exactly, that should make the process instance completed if there are not other nodes in line.  Things to verify:

              - does processId is correct process instance id?

              - does the work item id points to the correct work item?

              - how do you verify if process instance is active?


              to trace it you could register DebugProcessEventListener to see what is invoked and in what order.

                - process ID and workitem ID are correct.

                - the signs that process is still alive are:

                • it is under "Active" tab in the console
                • there is still respective record in SESSIONINFO (i use PER_PROCESS_INSTANCE strategy)
                • there are no records of EndEvent for the process in NODEINSTANCELOG

                  would it be possible to get a reproducer to see what can be the issue?

                    Hi Maciej!


                    Actualy, issue has gone today on it's own. I agree with you that there should be no flaws from jbpm side in the scenario I described above.

                    I guess the reason was in distributed tx management in our app, which was fixed.

                    I really have no idea what caused and solved this issue)


                    Thank you for your advice. It helped to understand deeply what's going on.

                    Consider this solved.
