Gonzalo,
You want to use AbstractDefaultAjaxBehavior as context to serve some JSON?
Then what you do is
add(behavior = new AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
TextRequestHandler handler = new TextRequestHandler(...);
RequestCycle.get().scheduleRequestHandlerAfterCurrent(handler);
}
});
then use use behavior.getCallbackUrl() to generate the URL you need to use
on client side to retrieve that JSON.
