[Rails 3] Routing Error ... but the route is open ... (not the 66 !)

I have in my routes.rb (I am using Devise authentification ...)   devise_for :users, :singular => :user, :path => :user   as :user do     get "user/changeEmail", :to => "user/ credentials#change_email", :as => :user_changeEmail     post "user/updateEmail", :to => "user/ credentials#update_email", :as => :user_updateEmail   end

running rake routes I can see : ...    user_changePassword GET /user/changePassword {:controller=>"user/credentials", :action=>"change_password"}    user_updatePassword POST /user/updatePassword {:controller=>"user/credentials", :action=>"update_password"} ...

user_changePassword_path display correctly the form

= form_for @user, :as => :user, :url => user_updatePassword_path, :html => {:method => :put} do |f| ..

and the submitting the form should send data to :url => user_updatePassword_path but there is a routing error in the console
