Hi, in case of a regular session you can use a HttpSessionListener and use the public void sessionDestroyed(HttpSessionEvent event), similar to that one here: https://stackoverflow.com/questions/7756054/how-to-call-a-method-before-the-session-object-is-destroyed (wicket is still a java framework, meaning all underlying java web things usually just work)
Also AFAIK the page should not get detached as long as the page is still active, meaning it has AJAX panels on it that are still doing things, maybe MartinG can shed some light on this; Best, KB ----- Ursprüngliche Mail ----- > Von: "yvus" <yves.courvois...@enata.com> > An: users@wicket.apache.org > Gesendet: Mittwoch, 26.
