Hello, In our application we have a ModalWindow (Which resides in another ModalWindow...) which responds with a 404 error when opening. In the log a ClassCastException appears. This problem only occurs in IE8. It works fine in IE9, Chrome and Firefox.
It looks like it's the same problem described in the issue WICKET-4241. The issue states that the problem is solved in version 1.5.4. But we use Wicket 1.5.7 in our application. Anyone knows what the problem might be? Thanks, Rick
