Howard, I dont want to extend this (or any other) issue too far, but:
I know how much work is involved in instantiating my page's (or component's) Java object, because I have it right in front of my eyes. If the overhead is in the superclass (AbstractComponent, BaseComponent), that could be factored out via delegation, so that it would end up being a simple dozen-byte bean. Anyway, this was just a comment without the expectation that it would trigger a rewrite of the framework. Christian ---- Original message ---- >Datum: Mon, 16 Dec 2002 06:40:07 -0500 >Von: "Howard M.
