[jboss-user] [JBoss jBPM] - [jBPM4] Error while creating processinstance having timers

[rams.rapo]

Hi,

I'm able to deploy below process definition but fails why creating process instance out of it. Transaction seems to be null.

  | <process name="JobExecutor" xmlns="http://jbpm.org/4.0/jpdl">
  | 
  |     <start g="19,50,48,48">
  |         <transition to="guardedWait1"/>
  |     </start>
  | 
  |     <task name="guardedWait1" g="98,46,127,52">
  |         <transition name="go on" to="next step" g="-16,-17"/>
  |         <transition name="timeout" to="guardedWait2" g="-43,-16">
  |             <timer duedate="3 minutes"/>
  |         </transition>
  |     </task>
  | 
  |     <task name="guardedWait2" g="98,46,127,52">
  |         <on event="timeout">
  |             <timer duedate="5 minutes"/>
  |             <event-listener class="test.TaskEscalateHandler"/>
  |         </on>
  |         <transition name="go on" to="next step" g="-16,-17"/>
  |     </task>
  | 
  |     <end name="next step" g="283,46,83,53"/>
  | 
  | </process>

I do have jboexecutor defined in my jbpm.cfg.xml

<import resource="jbpm.jobexecutor.cfg.xml"/>

I may be missing something really simple here...any pointers?

Thanks
