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/browse_thread/thread/b84154e5228bf9f3 which 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.
