I'm using ActiveAdmin (0.4.0) with Rails (3.1.1).

I can't find a nice way/hack to handle multiple nested resources.

Considerer 3 models as: 

class Program < ActiveRecord::Base
  has_many :knowledges, :dependent => :destroy
end

class Knowledge < ActiveRecord::Base
  belongs_to :program
  has_many :steps, :dependent => :destroy
end

class Step < ActiveRecord::Base
  belongs_to :knowledge
end

And the ActiveAdmin resources: 

ActiveAdmin.register Program do
end

ActiveAdmin.register Knowledge do
  belongs_to :program
end

ActiveAdmin.register Step do
  belongs_to :knowledge
end

In routes.rb: 

namespace :admin do
  resources :programs do
    resources :knowledges do
      resources :steps
    end
  end
end

Here's the urls for the index of the programs, the knowledges and the steps :
http://localhost:3000/admin/programs
http://localhost:3000/admin/programs/1/knowledges
http://localhost:3000/admin/programs/1/knowledges/1/steps

No problem for the "Knowledge" admin but the "Step" admin don't keep the nested context.

For example, when I use filters in steps#index I'm redirected to:
http://localhost:3000/admin/knowledges/1/steps?params...
But it must have been:
http://localhost:3000/admin/programs/1/knowledges/1/steps?params...

Same problem when I create a new resource:
http://localhost:3000/admin/knowledges/1/steps/new
Instead of:
ruby-on-rails-3 activeadmin
