Injected hibernate session breaks removal of event scoped stateful session bean ------------------------------------------------------------------------------- Key: JBSEAM-2311 URL: http://jira.jboss.com/jira/browse/JBSEAM-2311 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 2.0.0.GA Environment: JBoss 4.2 Reporter: Marcus Schmidke When using a JPA delegate as injected Hibernate session as suggested in chapter 8.4 of documentation, the removal of an event scoped SFSB breaks because when Seam intercepts the @Remove method and tries to inject the Hibernate session, the EntityManager will be already closed. components.xml: <persistence:managed-persistence-context name="entityManager" auto-create="true" persistence-unit-jndi-name="java:/EntityManagerFactories/Argos3EJBPU" /> <factory name="session" scope="STATELESS" auto-create="true" value="#{entityManager.delegate}" /> SFSB: @Stateful @Name("aufgabenliste") @Scope(ScopeType.EVENT) public class AufgabenlisteImpl implements Aufgabenliste { @In private Session session; @Remove public void remove() { } } Gives the following exception upon closing of the event context: 13:02:25,091 WARN [Component] Exception calling stateful session bean default @Remove method: aufgabenliste javax.ejb.EJBException: javax.el.ELException: Error reading 'delegate' on type org.jboss.seam.persistence.EntityManagerProxy at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:63) at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:83) ...
