Hello, I think I have found a bug in NewProcessInstanceFacade.java. Field _keyPath is never set. I think there should one more line in the constructor of the class NewProcessInstanceFacade _keyPath= config.getAttribute(Constants.KEYPATH); Constant "Constants.KEYPATH" does not exist yet. But according to bpm_orchestration3 in jbossesb-4.2.1.IR2 the value of that constant should be "key"...
