[jboss-user] [jBPM Users] - Re: How to suspend Join Execution

[saraswati.santanu]

Pradeep,
   your problem is not very clear to me. It will be helpful if you can provide some code that can get the exception.

  However, whatever I understood, an approach may be to add a start event listener on the join node and delete the tasks you do not need when there is a request for rework. A sample code for the start event listener of the join node may be like this:

  |    public void notify(EventListenerExecution execution) throws Exception {     
  |     	Task task = //find the task you need to invalidate
  |     	//ugly casting. Is there a better way    	
  |     	((TaskImpl)task).setExecution((Execution)null);
  |     	((TaskImpl)task).setExecutionDbid(null);
  |         //now delete the task
  |         taskService.deleteTask(task.getId());
  |    }
  | 

You can always check and see if there is a better way to delete an existing task.
