Hi all,
     I am using WS-HumantaskSservice(5.2) for our humantask  implementation. We could create and could do task operations successfully. 
But now we include subtask strategy("onAllSubtasksEndParentTaskEndStrategy") also. Problem is that when we complete the tsubtask, the below exception is thrown. Please help...
I passed knowledge session to workitem handler as mentioned in another discussion.
