I created the above process, if I run the process inside the JBPM console, even though I completed the Create task, it still stops there, not moving forward, the task apprently has been consumed. so no task to complete,but the workflow stucks at the first task.

If I run the same process through web service, I can start the process, claim the Create task, but when I tried to complete the Create task, I got the following exception:
