NullPointerException In CachedResourceBuilder

[amrishtandon]

I am getting the following on my WAs 7.0 server when I attempt to use the CachedResourceBuilder:

If I remove the CachedResourceBuilder, all errors go away. I need the CachedResourceBuilder so that I can get proper URLs for the CSS files and javascript files.

Any ideas? This is a critical issue for us to be able to use richfaces in production.

https://jira.jboss.org/jira/browse/RF-3586 - the only related jira I could see. hope could help a bit. check comments from Nick.

Ilya thanks for the response. The Jira entry really did not help. Is there anyway to turn the caching off? also is there anyway to know what CSS and Javascript files are required by each component, so that I can extract them and call them dieclty from my pages?
