title: returning to welcome page on session destroyed in jsf
body: <p>I have implemented a session listener. i want that when a user tries to use the site after his session is destroyed, he should be redirected to the welcome page (login page).
  I have tried this by doing <code>loging?faces-redirect=true</code> but i have to click twice before i am really redirected to the loginpage.
  Further, when session expires when on the welcome page (login page). the application crashes as shown in the following errors:</p>
