Solution in this thread: http://www.nabble.com/MyFacesExtensionsFilter--t1756467.html
Basically, in web.xml the mapping for filter MyFacesExtensionsFilter needed to be*.jsp not *.jsf. I copied *.jsf from http://myfaces.apache.org/tomahawk/extensionsFilter.html <filter-mapping> <filter-name>MyFacesExtensionsFilter</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> -- View this message in context: http://www.nabble.com/1.1.4-panelNavigation2-TILES-extensionFilter-t1756195.html#a4777936 Sent from the MyFaces - Users forum at Nabble.com.
