Hi, nort! it seems there is some problem with your JBPM Context. Seems like it is closed upon entering your task node "Urlaubsantrag entscheiden". And this is the reason for not resolving the assignment expression. Since you are entering the task node it means that the process has already left its start state with no problem, i.e. the first swimlane assignment is correct. Check if you are calling JbpmContext.close() somewhere in the middle. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978076#...
