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

[philso]

Hi Ronald thanks for your reply. I've noted your comment about events & actions above node level,very useful thanks.

Please disregard the previous post as I've simplied the Process Definitions to:


Main Process Definition (ExpenseReport4)


 And the Sub Process (ClaimVat)

I've pulled out my code into a simple test block as below. This code goes through the transitions in both the main Proc Def & its two sub processes. The sub processes use the same proc def (ClaimVat.xml). I've included in the codes comments what I would expect to see versus what I am seeing. Any help would be greatly appreciated.
Best regards, Phil
