I am getting a strange TransientObjectException (in Hibernate) when attempting
to call JbpmContext#save(ProcessInstance). In specific, it is complaining of
'org.jbpm.graph.def.Node' (probably not very helpful to you guys) when the
Hibernate session is closed.
In memory, jPBM behaves fine. When attempting to persist to HSQLDB, I get the
aforementioned exception. I have verified that the jPBM tables do exist in the
file storing my JBoss local HSQLDB in the file system.
This error has me totally stumped. I saw several other search hits via Google,
but none when simple trying to save a ProcessInstance for the first time. Any
assistance would be greatly appreciated.
My thanks in advance,
Saish
