In this case an event is fired, after the process ends,   to handle the on end event. But this results in a null pointer exception because there are no more activities or transitions at this point. UserCodeReference.getProcessDefinition returns null. My basic problem is : How do I end a Process Instance if the join is not reached due to an error transition from one of the nodes feeding the join. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555086#555086] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
