Can't have WelcomeController and User::WelcomeController ? namespace anyone !

I have a top level controller and a nested controller with the same name WelcomeController.

It works fine in development mode.

Then in production mode, it says there are no actions for that controller, and plops out this error...

/usr/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/ inflector.rb:250: warning: toplevel constant WelcomeController referenced by User::WelcomeController

Is'nt that the whole point of modules, there basically a namespace to keep this from being a problem ???
