    event org.jboss.seam.preDestroyContext.SESSION and no transa

    Ricardo Memoria Novice

      I'm trying to map a session logout and I've implemented using events in a SEAM way

      <event type="org.jboss.seam.preDestroyContext.SESSION">
       <action expression="#{authenticator.logout}"/>
       </event>
      


      and the code is

      @Transactional
      public void logout() {
       if (identity.isLoggedIn()) {
       userLogin = entityManager.merge(userLogin);
       userLogin.setLogoutDate(new java.util.Date());
      
       entityManager.persist(userLogin);
      
       System.out.println("Logout: " + userLogin.getUser().getLogin());
       }
      }

      The problem: The logout date is not recorded, i.e the entityManager.persist doesn't take effect.

      I also tryed an entityManager.flush(); after entityManager.persist(userLogin); but it raises an exception

      I have no idea how to work around that. Any tip?
