Hello everyone, i've got a problem with some code (mainly copied from the booking example). I use Jboss AS 4.2.2 with SEAM 2.0.0. The Booking-Example works fine.
However my own page pr_overview.xhtml: | <ui:composition xmlns="http://www.w3.org/1999/xhtml"; | xmlns:s="http://jboss.com/products/seam/taglib"; | xmlns:ui="http://java.sun.com/jsf/facelets"; | xmlns:f="http://java.sun.com/jsf/core";
