I am trying to setup ajax4jsf with shale and facelets

[Anthony Sykes]

I followed the setup steps outlined on the Shale site but I keep getting a NullPointerException thrown from facelets. Here is the stack trace:

Has anyone been able to successfully use shale with ajax4jsf and facelets together? Has anyone encountered this problem and found a fix for it?
