      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
