Thanks for the response Bernd. We want to do the dynamic case as you mentioned secondly. But we don't necessarily need to change the process definition itself. It would be ok if we could change some code an action was calling (maybe via a web service??). It would be cool if dynamically changing the process definition were supported in the future. I think when you get into the really long running processes the requirement becomes more visible. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4047965#...
