[jboss-user] [JBoss jBPM] - Error Creating Timer on Task Instance Create

[johnhurtchan]

Please help. I added a Timer for my Task. But during execution, when the task instance gets created, then it tries to create the Timer, I get this exception...

DEBUG GraphElement : event 'timer-create' on 'Task(MyTask)' for 'Token(/)'
  | DEBUG JobSession : cascading timer save to timer action
  | ERROR GraphElement : action threw exception: uninitialized proxy passed to save()
  | 	org.hibernate.PersistentObjectException: uninitialized proxy passed to save()
  | 	at org.hibernate.event.def.DefaultSaveEventListener.reassociateIfUninitializedProxy(DefaultSaveEventListener.java:49)
  | 	at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:59)
  | 	at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:535)
  | 	at org.hibernate.impl.SessionImpl.save(SessionImpl.java:523)
  | 	at org.hibernate.impl.SessionImpl.save(SessionImpl.java:519)
  | 	at org.jbpm.db.JobSession.saveJob(JobSession.java:99)
  | 	at org.jbpm.scheduler.db.DbSchedulerService.createTimer(DbSchedulerService.java:43)
  | 

My processdefinition looks like this...

<task name="MyTask">
  | 	<assignment	class="MyAssignmentHandler"></assignment>
  | 		<timer duedate="1 day"><action class="MyActionClass"/></timer>
  | </task>

Its not executing my Action class yet because it can't even get pass creating the Timer.  Anyway my Action class looks like this...

public class TaskReminderEmailNotificationAction implements ActionHandler 
  | {
  | 	private static final long serialVersionUID = 1L;
  | 	public void execute(ExecutionContext ctx) throws Exception 
  | 	{
  | 		TaskInstance taskInstance = ctx.getTaskInstance();
  | 		taskInstance.getActorId();
  | 		EmailNotification.notify(taskInstance);
  | 	}
  | }

And that EmailNotification.notify(TaskInstance) method looks like this...

public static void notify(TaskInstance taskInstance) throws Exception
  | {
  | 	String taskName = taskInstance.getName();
  | 	Object p = ((Object)taskInstance.getContextInstance().getVariable("object"));
  | 	Message msg = new MimeMessage(session);
  | 	Transport.send(msg);
  | }

Any ideas why it can't even create the Timer?
