Exceptions after calling jbpmContext.close - Please Help

[bloreguy]

After business processing (creating a new process instance, and signalling twice), I close the jbpmContext and see these errors. Please help me in understanding what they might be about.

I also have a Hibernate Session in the same class, injected by Seam and set this session in jbpmContext using setSession, while creating jbpmContext.

On a side note, if I dont close the jbpmContext, I dont see the taskinstances and processinstance jbpm tables updated in the database. They get updated only when I call jbpmContext.close. Alos, the processinstance and taskmanagementinstances are not autoSave entries - They are newly created entities.

If there is an option of not calling jbpmCOntext close, I at least have an option of going forward in my project

I think that you've got two hibernate sessions open for some reason. See the documentation http://docs.jboss.com/jbpm/v3/userguide/persistence.html#injectingthehibernatesession and http://docs.jboss.com/jbpm/v3/userguide/persistence.html#d0e2412

JbpmContext.close commits the hibernate session to your database. So you do kind of need to close the context in a finally block.
