I've tried with Seam 1.1.5 and 1.1.6 using IceFaces 1.5.2. When I try to login I get the following error: javax.faces.el.EvaluationException: Exception while invoking expression #{authenticator.authenticate} This method exists so I assume that the problem is with the FaceletViewHandler? Is there some config change that I can do to get around this? Cheers, Damian. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013289#...
