[jboss-user] [JBoss jBPM] - Re: Exception on Timer-Execution under Weblogic

[syngolis]

No ActionDelegation. Just plain JPDL:

   <state name="State1: Wait 1 minute">
  |    	<timer name='waitstate' duedate='1 minute' transition='to_task1' />
  |       <transition name="to_task1" to="Task1: WaitState is over"></transition>
  |    </state>
(Working under JBoss)

I did a little mor research. The timer becomes executed. The problem appears at the cancelling of the timer:
