I think without it, although the process starts, it gets 'stuck' in the start state. Over the past 9 months my understanding of jBPM has improved a lot, and I'm begining to tackle the various issues (like that node exit) that are left over from early experiments - hence why I'm trying to get some jUnit tests going for the jBPM usage in the app. All I was hoping for with this thread was to get some ideas as to why the DelegationException is thrown when I invoke createStartTaskInstance() from a jUnit test, but NOT when the same code is run as part of the normal running of the app. I had assumed that the range of possible causes for that exception had probably been experienced by someone. I'm still hoping that someone will give me some guesses or suggestions for investigation. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194564#...
