3:47 p.m.
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
18:45:39,218 ERROR [[/mdrtb-moldova]] Session event listener threw exception

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