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:
http://community.jboss.org/servlet/JiveServlet/showImage/2-561928-7482/subprocess_in_fork.JPG http://community.jboss.org/servlet/JiveServlet/downloadImage/2-561928-7482/450-108/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!
Phil
