Yop !
While playing with unstructured joins (join based on incoming transitions) I noticed that the incomingTransition attribute of Node.java was not propertly initialized in the ProcessBuilder.java.
This initialization is delayed when a new transition is added and is expected to be handled in the resolveDestinations method. I added the call to the addIncomingTransition method there because it was missing.
I've commited this change.
