Hi,
I have a major problem that I am finding hard to debug. I am using version 3.2.2 of jbpm
on weblogic 9.2. I have an stateless session bean that is using container managed
persistence. The problem I am seeing is that when I make the transition to an end state
in the graph it is falling over. Transition to any other state is ok. The stack trace I
get is given below. Essentally it's saying
Caused by: org.hibernate.SessionException: Session is closed!
I have remote debugged right through my own code and the jbpm code. It's only once
all the code has executed and the enterprise bean tries to commit the transaction that it
happens. What baffles me is why it is only the case for the end states. Apologies that I
haven't provided much info but it's difficult to know what would be relevant.
I'm totally lost. I'm hoping someone will have a few hypthesis that I can test
out. By the way I had my code working on an earlier version of jbpm!
cheers
Richard.
