------------------------------------------

Jeremy, 

I posted this on mailinglist, but just got a workaround:
http://apache-wicket.1842946.n4.nabble.com/Modalwindow-with-confirm-box-on-close-button-td3014935.html

I don't know how overriding the close function can solve my problem. Maybe I can explain better with an example of something we use very often:
  WebMarkupContainer btnSubmit = new WebMarkupContainer("btnSubmit");
  btnSubmit.add(new AjaxFormSubmitBehavior("onclick"){
    protected void onSubmit(AjaxRequestTarget target) {
    }

    protected CharSequence getEventHandler() {
      String confirmText = "...";
      return "if(!confirm('" + confirmText + "')) return false;" + super.getEventHandler();
    }
  });

When overriding the close function or the closeButtonCallback, it's to late. My confirmbox should be just before going back to the server. Or am I missing something? 

Many thanks. Kind Regards, Marieke Vandamme

> I would like to add extra client-side scripting that is executed before the modalwindow is closed. 
> Now you can already add server-side with overriding onCloseButtonClicked, but then the window is already closing. 
> I need this because I want to show a confirm-box to the user, so that he can confirm that he wants to close the window.
