>
> If component wants prepend javascript in ajax request, the only way to do it
> is register itself like listener in ajax request and then implements
> method AjaxRequestTarget.IListener.onBeforeRespond. This method is called
> before prepending. Other methods (like onRender, onBeforeRender, ...)
> are called AFTER prepending, so they can't be used for...
> It works, but problem is, who will register this component? Now, it must be
> registered manually in ajax method and this method
> must know, that this component will be rendered in this ajax request. And
> this is very bad.
> In other words, component has no chance to register itself BEFORE
> prepending...
> I think, that there should be some method (like onBeforeRender) called in
> AjaxRequestTarget.respond() BEFORE prepending (called on every component)...
