Martin Putz commented on JBPM-2036:
-----------------------------------
The problem is that the CancelTimerAction, which is invoked because the state is left,
deletes the timer, but since 'repeat' is defined, the Timer still tries to update
the dueDate attribute. When Hibernate attempts to persist this change, the
StaleObjectStateException is thrown because the timer has been deleted already:

StaleObjectStateException when repeating timer signals the token
----------------------------------------------------------------
Key: JBPM-2036
URL: https://jira.jboss.org/jira/browse/JBPM-2036
Project: JBoss jBPM
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: jBPM-3.2.5.SP1, jBPM 3.3.1 GA
Reporter: Martin Putz
Assignee: Thomas Diesler
Fix For: jBPM 3.2.6 GA
With the following timer definition on a state node
<state name='state1'>
<timer name='timer-to-end-with-repeat' duedate='1 second'
repeat='5 seconds'>
<action class='org.jbpm.scheduler.exe.TimerDbTest$Signal' />
</timer>
<transition name='to_state2' to='state2'/>
</state>
and the action class execute() method being
public void execute(ExecutionContext executionContext) throws Exception {
executionContext.leaveNode();
}
leads to:
2009-02-10 21:38:45,404 16508 ERROR

If 'repeat' is not set, the token is leaving the state as expected.
