In my 'execute' function in ActionHandler, I must call "executionContext.leaveNode()" at the very end. Since there can only be one Action in a given Node, I think leaveNode should be the default action after execution of ActionHandler, if user didn't call leaveNode in the actionHandler. Even in script, we also must call leaveNode after other work. And, if you updated some process variables, you must call executionContext.setVariable to set the updated values back, or the code get executed in the next node can't get the updated values. The reason is the code in the next node will be executed before the script interperter set the updated process variable back to ContextInstance. I believe this is really unconvenient for users. Is there anyone can give me a good reason for this? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977786#...
