XsltPanel extends Panel {
onComponentTagBody(...) {
// wicket renders markup into response so we create a standin that will collect the markup for us
StringBufferResponse response=new StringBufferResponse();
// swap the current response with the standin
Response old=RequestCycle.get().getResponse();
RequestCycle.get().setResponse(response);
// let the component render its body
super.onComponentTagBody();
// put the old response back
RequestCycle.get().setResponse(old);
String output=response.toString();
//transform the rendered output;
replaceComponentTagBody(...., output)
}
}
something like that might be used as a generic xslt transformer, if it works :)

Yes, I was not being clear with my question (my grasp of wicket is very
weak). I want to transform the markup being loaded from the markup file,
but *after* wicket has run it through the rendering process. What I want
to do is have wicket take the xml markup associated with the panel and
run it through its rendering process, and then capture that output
before it gets merged with the panel's parent, transform it with xslt
(into _javascript_ -- see my post from yesterday on wicket-contrib-gmap),
and then merge it with the panel's parent.
This way I am hoping to have _javascript_ rendered into the page that will
know about urls for wicket components. To me, it seems like a natural
way to have _javascript_ objects call wicket Link objects and AjaxHandlers.
Apologies if this sounds like babbling -- I'm still trying to find my
wicket legs.
thx,
