I'm using Seam 2.2.0.GA with Richfaces 3.3.2.SR1 and Facelets, Eclipse 3.4.2 and JBoss Tools 3.0.2.v200909151014R-H192-GA. When I develop a Facelets page all taglibs except the Seam taglib are recognized although declared xmlns:s="http://jboss.org/products/seam/taglib". Tags used within the page are also not rendered. E.g. <s:button id="test" value="test" /> renders to same in the page. jboss-seam-ui.jar and all necessary libs are in the classpath, richfaces works flawlessly. Does someone have a clue?
