Description

For normal rendering we have:

	/**
	 * 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;
	};

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.
