Hi Scott, first thank you for response. I do not know if you missed the part when I am saying that I do exactly the same thing when I have WAIT STATE as you described. The problem is how to do that when TASK is created/assigned. So, on task-create event you can call WS from action handler but then, it would be great if I can somehow receive callback (how, what to signal, resume, call from external app?) and then assign task by calling setActorId(). I hope that this gives more light to my problem. And I really hope, somebody has an answer. Thanks Milan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4142994#...
