    Hibernate TransientObjectException on JbpmContext Initial Sa

    Sascha Goldsmith Newbie

      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

      --- ENVIRONMENT ---

      * HSQL DB (installed with JBoss 4)

      * jPBM 3.1

      * EJB 3.0

      * Hibernate 3.2.0-CR1 (default with JBoss 4)

      * JBoss AS 4.0.4-CR2 (installed with JBoss 4)

      * JDK 1.5

      * Windows XP
