You could just include the logo panel on the page and uses straight jQuery to
show and hide the logo panel. You wouldn't need the Ajax timer and your
extended OpenOnLoadModalWindow class. It should then be able to support the
back button. You could also determine if the user has been to your app before
in the same session and choose to show the logo or not (there are a few jQuery
plugins that can help with determining that)
With Wicket 6 my understanding is that jQuery will be included by Wicket so
this may be even easier to do in 6 and all in Java code. I have not looked at
version 6 yet.
