Hi,
I have a question about how to restart a completed usertask.
It means  when a usertask is completed,its status is 'completed' in database.
In my javacode,I got the completed usertask by taskid.

   BlockingTaskSummaryResponseHandler taskSummaryHandler = new BlockingTaskSummaryResponseHandler();
   BlockingGetTaskResponseHandler response = new BlockingGetTaskResponseHandler();
   taskClient.getTask(8, response);
   Task task1 = response.getTask();


then I tried to start the task again.......

   BlockingTaskOperationResponseHandler taskOperationHandler = new BlockingTaskOperationResponseHandler();
   taskClient.start(task1.getId(), "john", taskOperationHandler);
   taskOperationHandler.waitTillDone(1000);

but exception occured:


org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'john']' was unable to execution operation 'Start' on task id 8 due to no 'current status' matchines

 at RollBaskTest.main(RollBaskTest.java:105)



because the status was not 'Reserved' so I counld not use the method start() to restart it.

is there anyway to change the completed usertask's status(from completed to reserved)

Looking forward for your guidance.
Thank you!

Jeffery
