I'm running RichFaces 3.2.1 with JSF 1.2 on a WebSphere 6.1 (the app is smoothly running in a JBoss & Tomcat environment too). During startup of the app the following exception is thrown

It seems that the faces-config.xml deployed within on of the rich-faces jars can't be processed. Don't know yet what the consequence is. Seems that most of the app's functions are working.

Still I see that no styling/theme is applied to the rich-faces ui components as they pretty much show plain HTML.

Anybody there who has worked an a thing like that? Would appreciate any hint to fix this!
