Help with "A copy of ApplicationController has been removed from the module tree but is still active!"

Hi,

I am on Edge Rails, hence with the new dependencies mechanism.

I am trying to get the plugin "acts_as_wizard" (to work.

I have refactored it to use the new plugin loading system, as best I know how:

Key part:

module ActsAsWizard   module ActionControllerExtensions

    def self.append_features(base)       super       base.class_eval do         cattr_accessor :wizards # Hash, contains all the wizards this controller participates in           alias_method :original_url_for, :url_for           alias_method :original_render, :render           prepend_before_filter WizardSetupFilter       end     end

....etc.....

Note I changed the filter to prepend.

THis may be related to the problem I have, which is that when I am in a wizard, in one of my before_filters defined in my ApplicationController, I get a "A copy of ApplicationController has been removed from the module tree but is still active!" error halfway through the filter.

Does anyone have any idea what sort of thing causes such an error? or just any tips for debugging problems with the edge rails dependencies mechanism. It's really opaque to me at this point.

If I do this: config.load_once_paths += %W{ #{RAILS_ROOT}/app/ controllers }

things work. But I really hope there is another solution and I am not
doomed to have to restart the development server for every controller
change for the rest of the life of the project.
