Problem with RESTful resource and ActiveScaffold

Question

Hello everyone, I am trying to use a RESTful controller for user inside a namespace using AS and one outside for registration and so on. When i try to visit the namespaced url I get Unknown action. Once i replace active_scaffold :users with a def index; end i can the URL. My routes look like:

  map.register "register", :controller => "users", :action => 
"create" 
  map.resources :users 
  map.resources :user_sessions 
  # Sample resource route within a namespace: 
   map.namespace :admin do |admin| 
     admin.resources :users,     :active_scaffold => true, :has_many 
=> [:events] 
     admin.resources :contracts, :active_scaffold => true 
     admin.resources :houses,    :active_scaffold => true, :has_many 
=> [:rooms, :photos, :contracts] 
   end

And my UsersController

class Admin::UsersController < ApplicationController 
    before_filter :jquery_noconflict 
    before_filter :authorize_admin 
    layout "admin" 
    active_scaffold :users 
end

There is also a UsersController in the app directory for signup, user editing and so on (RESTful)

Thank you
