Hey, I overided only jsf-impl.jar, regarding faces-config.xml file, it's almost empty, I only have the 'com.sun.facelets.FaceletViewHandler' for the facelets viewer handler and 'org.jboss.seam.jsf.SeamPhaseListener' which is the seam listener, thats all. Anyway, if the previous error stopped showing (due to the use of the old jsf-impl.jar) then there's no reason to stop the WebappLifecycleListener, correct? if so, what's there's left to do? :-/ Thanks pal.
