modal window navigation?

[Ryan McKinley]

Hello-

I'm using a Page within a modal window and when the user clicks an  
'OK' button, I want to refresh the whole page (not the modal window).  
I've tried a few variations of:

    form.add( new AjaxButton("actionSave")
    {
      @Override
      protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
        getRequestCycle().setResponsePage( ExplorePage.class );
      }
    });

but that refreshes the iframe, not the page.

Any pointers?

For extra credit...  what is the easiest way to make the modal window  
background darker?  Do I need to extend the modal window and include a  
different CSS file?  what is the best practice for this kind of thing?

thanks!
