Hi,
I have some problem with timers.
In my process definition I have a timer in some state:
<state name="watering">
| <timer name="timer_eb"
| duedate="2 minutes"
| transition="overdose" >
| <action
class='com.comarch.oss.core.controller.UIControllerHandler' />
| </timer>
| ...
| </state>
I expect that timer will fire 2 minutes after state enter and defined
transition and action will execute.
But nothing happens.
Instead of that in server.log file I found:
2007-09-17 13:16:26,250 DEBUG [org.jboss.ejb.txtimer.TimerImpl] run:

What does that error (org.jbpm.JbpmException: couldn't execute timer) stand for?
How to resolve it?
Best Regards,
