[jbpm-users] [jBPM Users] - Ending task with timer - session is closed

Hi, I'm using following configuration: JBoss AS 4.3 jBPM 3.2.2 Seam 2.0.2 Hibernate 3.3.0 jBPM is configured to use JTA. JbpmContext is injected with Hibernate session took from Seam managed EntityManager. When I end task, which has a timer, everything works fine but at the end of rendering phase exception is thrown: | 02:50:26,345 ERROR [TaskMgmtSession] org.hibernate.SessionException: Session is closed! | 02:50:26,438 ERROR [SeamPhaseListener] uncaught exception | org.jbpm.JbpmException: couldn't get task instance '146' | at

Has it something to do with JobExecutor? Or any other suggestions? Thank you. regards, Jakub View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257770#...
