In the seam documentation it says:

Event key: org.jboss.seam.security.alreadyLoggedIn
Raised when a user that is already authenticated attempts to log in again.

But this is never fired.
I have this listener:

  @Observer("org.jboss.seam.security.alreadyLoggedIn")
    public void alreadyLoggedIn() {
         //If we have a user still
         SystemLog sysLog = new SystemLog();
         sysLog.setCategory(Messages.instance().get("security"));
         sysLog.setUsername((currentUser == null ? "" : currentUser.getUsername()));
         sysLog.setDescription(Messages.instance().get("user.alreadyLoggedIn"));
         sysLog.setDate(new Date());
         entityManager.persist(sysLog);
         
         //Logout the user and throw exception
         Identity.instance().logout();
         //throw new SaksappException("Brukeren er allerede logget inn");
    }

Why doesnt this work?
