What you need to think about is separation of processes. You need to ignore the node enter on to your Node(First) That happened with the previous signal, and does not happen in the signal while your token is in 'First' For example, we have a simple graph, made of 2 simple nodes, A and B. Currently your token is on A. You would then signal the token. Before Signal gets fired. The signal would cause the token to leave A. Leave Node (for node A) fires The token would then enter Node B Node Enter (for node B) fires The token would then be done signalling After Signal You're going to see node leave/enter for 2 separate nodes across a signal event, since that signal causes the transition. The signal method is just a way to tell the token to move to the next node/state/etc on a specific transition). You have to signal the token (ending a task does this as well), for it to move to the next node, which is why you have to have a begin signal before you can have a leave node.

Read the logging again The token is in state "first", then you signal it and get the following logs: | 13:34:14,151 [Thread-0] DEBUG GraphElement : event 'before-signal' on 'State(first)' for 'Token(/)' | 13:34:14,151 [Thread-0] DEBUG GraphElement : event 'node-leave' on 'State(first)' for 'Token(/)' | 13:34:14,151 [Thread-0] DEBUG GraphElement : event 'transition' on 'Transition(to_end)' for 'Token(/)' | 13:34:14,151 [Thread-0] DEBUG GraphElement : executing action 'action[action]' | 13:34:14,167 [Thread-0] DEBUG VariableContainer : update variable 'message' in 'TokenVariableMap18b81e3' to value 'About to finish!' | 13:34:14,167 [Thread-0] DEBUG GraphElement : event 'node-enter' on 'EndState(end)' for 'Token(/)' | 13:34:14,167 [Thread-0] DEBUG GraphElement : event 'process-end' on 'ProcessDefinition(cpob)' for 'Token(/)' | 13:34:14,167 [Thread-0] DEBUG GraphElement : event 'after-signal' on 'State(first)' for 'Token(/)' | Which is correct, you get a - before signal (which is a way of telling the system: 'hey there is a signal comming' - then you leave state "first" - you are taking the "to_end" transition" - you enter state "end" - the process ends - the signal is completely processed So there is nothing wrong with your logging, you just read it wrong. Remember, jBPM does nothing unless you signal it in one way or another. If you start reading the log from the moment you signal it, everything is correct View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3953991#3953991 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3953991 Using Tomcat but need to do more?

|
The program's main part is as simple as that
| ...
| while(!instance.hasEnded()){
| System.out.println("*** signal ! ***");
| instance.signal();
| }
|
As you can see, I get the same order than previously.
nodeEnter > beforeSignal > nodeLeave > afterSignal
But I was wondering about some logs having exactly the same time, I did a
program that writes the running class name to a disk and to my surprise, the
launch order is still the odd looking one.
In my opinion, it would had been more intuitive to have something like
nodeEnter > (signal sent) > beforeSignal > afterSignal > nodeLeave
Although I don't get the use of the *Signal methods, should look deeper into
the documentation.
Thanks Cpob

[JBoss-user] [JBoss jBPM] - Re: State events fire order
I got a different order. You have to have a BEFORE SIGNAL, before you can even leave the node, then you leave the node, then you enter the NEXT NODE,a nd then it's the after signal. Below is the processdefinition.xml I used | | | | | | | | | | | | Going to the first state! | | | | | | | | About to finish! | | | | | | | | | BEFORE SIGNAL | | | | | AFTER-SIGNAL | | | | | NODE ENTER | | | | | Node LEAVE | | | | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3953777#3953777 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3953777 Using Tomcat but need to do more?
