James, taking Igor example why not providing simple marking interfaces in
the Core and then something like this in the Page implementation, (i was
thinking of the Dynamic Proxy approach you mention, but i'm not seeing why
it would be needed here since all you want is to propagate the Component
re-rendering into the current AjaxRequestTarget)
i.e: Defining a root Event named: AjaxEventResponseListener
then defining a simple method in base page:
protected void propagateAjaxEvent(Class<? extends AjaxEventResponseListener>
listener, final AjaxRequestTarget target) {
getPage().visitChildren(listener,
new IVisitor<Component>() {
public Object component(Component component) {
target.addComponent(component);
return CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;
}
});
}
