Hi Chris, I have struggled with this pattern myself. Ultimately I ended up using an eventing pattern to decouple the modal from the page components that need to be refreshed. I rolled my own event dispatch mechanism in Wicket 1.4 using event-specific interfaces and IVisitors that find all components that implement the interface. Wicket 1.5 has some baked in support for such a pattern which probably requires less boilerplate [1]. In any case, before closing the modal your ok button submit handler simply fires off the event.
Hope that helps!
