    can not end subprocess in concurrent execution (jBPM4.4)

    saig0 Newbie

      Hi!

       

      I have a problem with jBPM 4.4 when I try to end a subprocess instance in a concurrent execution.

      This image show an example process:  

      subprocess_in_fork.JPG

      The process should execute a subprocess and wait of a signal in the concurrent execution. When a signal arrive, an external activity behavior (end subprocess) should call that will end the subprocess and both executions will join.

       

      I can run this process correct with jBPM 4.3 but when i try to run with jBPM 4.4 the follow JbpmExecution  throw:

      I tried to end the subprocess instance like this:

      executionService.endProcessInstance(processInstanceId, "remove"); 

      (processInstanceId is the id of the execution in activity 'subprocess')

       

      I also tried to send a signal to this execution but it throw the same exception.

       

      It seems that I have to end the subprocess instance first, so I tried something like that but it doesn't work and throw the exception.

      public void endProcessInstanceByIdCascade(final String processInstanceId)    {
              Command<Object> command = new Command<Object>()        {
      
                  public Object execute(Environment environment) throws Exception            {
                      ProcessInstance processInstance = executionService.findProcessInstanceById(processInstanceId);
                      Execution subProcessInstance = processInstance.getSubProcessInstance();
                      if (subProcessInstance != null) endProcessInstanceByIdCascade(subProcessInstance.getId());
                      executionService.endProcessInstance(processInstanceId, "remove");
                      return null;           
                 }
              };
              processEngine.execute(command);
          }
      

       

      Did I make something wrong or is this a bug in jBPM 4.4?

       

      Thank you for help!
