Hi there, I''m trying to create a mock controller to test the use of UrlHelper in ActionMailer. I''m trying this: require ''d:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.0/lib/action_controller'' # Re-raise errors caught by the controller. #class DiscussionsController; def rescue_action(e) raise e end; end class MockController < ActionController::Base def

I can''t figure out why I''m getting the following error. There''s nothing wrong in my communities_controller file. And the helper for communties exists. Any ideas? Thanks, Joe NameError in <controller not set>#<action not set> uninitialized constant CommunitiesHelper app/controllers/communities_controller.rb:1 script/server:48 Show framework trace
