I just came across this myself. It is a bug with the component UIFormattedText. UIFormattedText extends UIOutput which sets the renderer type to "javax.faces.Text", but UIFormattedText doesn't have a renderer. UIFormattedText should be setting the renderer type to null in the constructor, but it doesn't. I found this in version 1.2.1 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074514#...
