> For normal rendering we have:
> {code:}
> 	/**
> 	 * We need to postpone calling beforeRender() on components that implement {@link IFeedback}, to
> 	 * be sure that all other component's beforeRender() has been already called, so that IFeedbacks
> 	 * can collect all feedback messages. This is the key under list of postponed {@link IFeedback}
> 	 * is stored to request cycle metadata. The List is then iterated over in
> 	 * {@link #prepareForRender()} after calling {@link #beforeRender()}, to initialize postponed
> 	 * components.
> 	 */
> 	private static final MetaDataKey<List<Component>> FEEDBACK_LIST = new MetaDataKey<List<Component>>()
> 	{
> 		private static final long serialVersionUID = 1L;
> 	};
> {code}
> Should there be similar functionality built in for Ajax update? It seems to be a typical problem that the feedback of an ajax update occurs too late.
