Hello all.

I am having a hell of a problem and it's driving me nuts. I get the
following error (undefined method `controller_name' for nil:NilClass):
but
only when config.action_controller.perform_caching = true

I googled around some and found this thread
http://groups.google.com/group/communityengine/bro...
suggests it may be a conflict with a pllug in controller but I don't
see any two controllers with the same name.

This particular controller is using activescaffold and I think that
might be
a part of the problem though I can't be sure.  As you can see from the
stacktrace rails has finished rendering the page and seems to throw a
fit
during sweeping.rb.  Also none of my controllers are mentioned in the
stacktrace.

What can I do to figure out why this is failing? This is driving me
nuts.
