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:   http://community.jboss.org/servlet/JiveServlet/showImage/2-561928-7482/su... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-561928-748... 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: com.ecg.mts.pcc.exceptions.PccException: EXCEPTION_tried to send signal: null to

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?
