RE: ModalWindow and reusable components
We wanted to make ModelWindowS more reusable in Wicket and so we created the ModalX project that is now part of WicketStuff. Not sure if it's what you're looking for but it certainly makes the use of ModalWindowS in our apps much more generic/reusable. https://github.com/wicketstuff/core/wiki/ModalX It comes in both 1.4.x and 1.5.x flavors.

Re: ModalWindow and reusable components
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!

Re: ModalWindow and reusable components
the window has a WindowClosedCallback you can use to refresh the appropriate part of the page once the window has been closed. -igor On Fri, Sep 23, 2011 at 8:48 AM, Chris Merrill ch...@webperformance.com wrote: In my short time with Wicket, I've found that whenever something seems really hard, I'm probably doing it wrong : I'm hoping this is such a case.
