Sorry Ronald but I still don't get your point I went one more time on the Node decision without more understanding on the subject. They talk about DecisionHandler but I've got ClassCastException when using it. I've noticed that when I add an action either Enter, Leave or Before Signal, my ActionHandler is always attached on an event. I don't see any way to add an ActionHandler not attached to an event. You're talking about testcase in Source, I've not seen any testcase in my directory C:\jbpm-jpdl-3.2.1\src. I'm sure I missed something, but you will be very helpful to me if you can provide me with the path of the testcase you are talking about.
