I think I managed to fire a user-defined event, but i cannot see the effect on the observer branch (the "Firing mail-delivered" message does appear on the console). Does this make sense at all? Can such an event be seen in another branch? (party branch) [task-node name="waitingforL1"] [task name="Waiting for L1" swimlane="ahstaff"][/task] [transition to="waitingforsendingL2" name="gotL1"] [script]System.out.println("Firing mail-delivered "); executionContext.getTransition().fireEvent("mail-delivered", executionContext);[/script] [/transition] [/task-node] (observer branch) [state name="waitingforallL1"] [event type="mail-delivered"] [action][script]System.out.println("mail-delivered event handled"); node.leave(executionContext);[/script][/action] [/event] [transition to="nextstep" name="gotallL1"][/transition] [/state] Thanks, Greg View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4176327#...
