> 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
