Thanks kukeltje, but I really don't know what information i omitted! Now I try to explain what I want to achieve, maybe someone can inspire me a new way. I want that, after a certain process task, each user in a set must execute a task. I don't know in advance how many users can be involved (i have a query to determine the set of users) this is why my process can't be fully designed in advance. any ideas? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138672#...
