i'm add session store listener for cleanup action

public int createUI() {
       ...
       RWT.getSessionStore().addSessionStoreListener(
				new SessionStoreListener() {

					@Override
					public void beforeDestroy(SessionStoreEvent event) {
                                                 // Perform cleanup     ...
                                        }
                                }

                     });
      RWT.getSessionStore().getHttpSession().setMaxInactiveInterval(10);
       ...
}

when run rap application, beforeDestroy() called if httpsession's timeout

...
UICallBack.activate( "callback id" );
...

but when i create some thread for update ui , beforeDestroy() never call if httpsession's timeout

PS. when i comment UICallBack.activate(), beforeDestroy() 's work if httpsession's timeout

what's wrong for my process?

Hi,
it seems that your UICallBack is active all the time. Thus, you have a
blocked UICallBack request which prevents the session from expiring.
That's why I suggest you to activate the UICallBack when you really need
it and deactivate it when it is not needed.
HTH,
Ivan
