[JBoss jBPM] - Error Creating Timer on Task Instance Create
by 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.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?
