Rails 2.3.* Engines 'A copy of ApplicationController has been removed from the module tree but is still active!' problem

If you use Rails engines and get 'A copy of ApplicationController has been removed from the module tree but is still active!' error as I did, put unloadable in your plugin controllers:

class MyPluginController < ApplicationController
unloadable

#your code here
end

Thanks Dimo
