This extension from JSF-Comp has Seam written all over it: http://jsf-comp.sourceforge.net/components/facelets-deployment/index.html "The facelets annotation project's goal is to relieve developers the burden of maintaining taglib.xml files. Instead, the code with this project allows developers to register validators, converters, functions and components with the facelets compiler. It also supports the registering of these components with the faces application." Just an idea... -Dan -- Dan Allen Software consultant | Author of Seam in Action http://www.mojavelinux.com http://manning.com/dallen NOTE: While I make a strong effort to keep up with my email on a daily basis, life and work come first and, at times, keep me away from my mail for a while.
