nested resource routes with members

hi,

lets say I have a Project that can have many Pages

Pages are acts_as_list so I have extra actions to move one "higher" or "lower" in the list

I have this in routes.rb

   map.resources :pages,                  :member => { :higher => :put,                                           :lower => :put }

   map.resources :projects do |project|      project.resources :pages, :name_prefix => "project_" # /projects/X/pages/Y    end

this works fine for all except the member ones for example, I can edit a page with GET /projects/99/pages/123/edit

but when i do PUT /projects/99/pages/123/higher I get "no route found"

I get no method on: project_higher_page_path("99","123") although this is fine: project_edit_page_path("99","123")

PS I am using Edge but not using the new routes resources. If this can be solved with that, i'd be happy to know how to do it that way.
