We have resolved the problem. I believe the issue was that we did not have the following in our faces-config.xml file: <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> We made a lot of modifications since then, which is why I'm not 100% sure if this was the change we made to fix this issue.
