    jbpm @CreateProcess with custom object going into process in


      Hi All

      Is it possible to placing a custom object (e.g. @Entity class UserDefined { }object) into the process instance, for the next stage in the process to pick up and work on.

      All the examples in Seam store the object in persistence and pass a reference to the object through the process instance, is it possible to just pass the object through the process instance as I don't want to place the object in the database untill I have done at least the second step in the process.

      I get this stack trace when I try to do this via:

      private Contact contact;

          Hi All

          A little update.. I have investigated this problem further, and it is unrelated to the variables "outjected" into the process instance. The problem is actually with the lookup of the ManagedJBpmSession (whilst invoking the @CreateProcess.

          The jbpm session it retrieves is null.

          I've got the startup listener as per the dvd store (with the process xml def changed). This works, I see the output on deploy. I've checked the jndi view and the jbpmsessionfactory is bound, but when the invoker hoes to fetch it, it returns a null session.

          Any help, anyone.

          I've deployed the dvd.ear and it works perfectly. I've tried using the exact same jars but still the same error. I am currently using jbpm 3.0.1 and jboss seam from cvs.

          Many thanks,
