Hi, I think I know what your problem is. You made that expression within a swimlane. That doesn't work. You must define the assignment expression in the task directly: e.g.: | <task-node name='Lets do it'> | <task> | <assignment expression='group(mygroupindb)' /> | </task> | <transition to='next' /> | </task-node> | Greetz, NiB View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4001545#...
