This is only necessary because the templates he's using are so crude and page-oriented. With a truly object-oriented framework like Wicket the problem goes away - you have a component hierarchy that parallels your model hierarchy, so e.g. your user panel just knows that a user has an address and hobbies etc., then the address panel just knows that it has a street name component and a zip component and so on. I wish I could find a framework that was properly object-oriented in any other language.
