JBoss Seam and logout [ENG]

If you wont do some action AFTER OR BEFORE logout in seam what we must do?
In seam documentation you only see than method Identity.logout
But in not complex solution. Spending some time i found simple and pretty solution - just invoke you own logout method and in this method do Identity.instance().login();
for example:

 public String logout() {
  // do something before logout
  String result = Identity.instance().logout();
  // do something after logout 
  return result;
 }

also you need extend logout method in Identity for postAuthenticate invoke

    public void logout() {
        super.logout();
        super.postAuthenticate();
    }

it prevent you from resend cookies back

one more thing. This is bug or not but if you use remember-me in seam logout will not work properly (JBoss Seam 2.0)
