[jboss-user] [JBoss jBPM] - Process State in a Fork not executing correctly

Hi, I have a test running that contains multiple nodes including two Process States. JPEG of the Process Definition is at:
http://picasaweb.google.com/lh/sredir?uname=phil.omalley&target=ALBUM&id=5287822354390912129&authkey=uuhzGmyCK8M&invite=CNzcsOsJ&feat=email
Process State 1 (LoadSubProcess1) is on the main path of execution. Process State 2 (LoadSubProcess2) is in a fork with two paths. I find I can execute my test fine up to the Process State in the Fork (LoadSubProcess2). My test can traverse fine through the first process State (LoadSubProcess1). When execution gets to the Fork alls well, child tokens are created OK but when execution is called on the transition into LoadSubProcess2 the Sub Process is not entered and the only available transition to this token is "fromLoadSubProcess2" (the transition after LoadSubProcess2). So it looks like the child tokens execution path cannot execute the Sub Process. For this test I've made LoadSubProcess1 & 2 point to the same ProcessDefinition xml so I know the xml is OK. The two other child paths execute fine and complete ok into the join node. The only difference I can see is one Process State call is made from the main execution path and the failing one is made from a child execution path. Does anyone have an idea what I'm doing wrong here? Many thanks for your time & effort.

| Had to add this state node here because the running tests we see the end state is never rested on when this process is used
