    Task Assignment results in two tasks with same id

    Michael Holtzman Newbie

      Hi. I have a simple AssignmentHandler that simply calls assignable.setActorId("xxxx"). However, when I query for tasks by calling getTaskMgmtSession().findTaskInstances(Actor) it lists two tasks with the same id number.

      Also, when I end the task by calling taskInstance.end() it ends the task but does not advance the token to the next node. Explicitly signaling the process instance after the task has ended does advance the workflow to the next node.

      Any thoughts? Thanx.

          Can you show us the processdefinition and the code of the assignmenthandler that you have written?

          Regards,
          Koen

              Hi Michael, your code is great and for one user works fine, but when i assign in the websale app (for example) to bernie, cookie monster a task, it does not say "task assignet to bernie, cookie", it doesn't say anything and the tasks are not assigned, am i doing anything wrong? Thanx
