I found that I have a NullPointerException in the my prerender code of my
ViewController but I don't get an error page. I have set
EXCEPTION_DISPATCH_PATH and it looks like when Shale does the redirect to my
error page, the redirect causes an IllegalStateException. I have MyFaces
default error handling on but I don't get an error page at all. Does anyone
know how I get my error page to display?
