Hi JBPM,

In my case,it's a approve process used JBPM5.3! Several days ago,i build a example no using JPA&JTA.And i could pass a result (just "agree" and "reject") value to a human task node while a want to complete this task by the following code.

     SyncWSHumanTaskHandler s = new SyncWSHumanTaskHandler();
     Map map = new HashMap();
     data.put("result", "agree");
     ContentData contentData = ContentMarshallerHelper.marshal(data,s.getMarshallerContext(), null);
     sTaskService.complete(taskId, userId, contentData);

and this human task's next node is a diverge gateway, it will used the mvel (like return result == "reject") to decide which sub switch way to go!Several days ago it could go easily without using JPA&JTA.

Today ,i add the JPA&JTA in my case.But a WorkflowRuntimeException was caught!

anyone can help me?
