Hello, The web app I'm using Trinidad on needs to be indexed by Google correctly and the Googlebot has just started crawling it. I've noticed that every time the Googlebot makes a request to the web app a NPE is generated and I don't want Google indexing the stack trace error.
I've been testing our web app today using the latest nightly build of Trinidad & Firefox's User Agent Switcher extension along with the following user agent: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) The stack trace generated on the first request is: Sep 8, 2008 12:38:05 PM com.sun.facelets.FaceletViewHandler handleRenderException SEVERE: Error Rendering
