Helper methods naming collision

I could reproduce this issue in rails 3.0.0.

module AHelper
  def foo
    'A'
  end
end

module BHelper
  def foo
    'B'
  end
end

class AController < ...
  def index
    render :inline => '<%= foo %>'
  end

class BController < ...
  def index
    render :inline => '<%= foo %>'
  end
end

/a => 'B'
/b => 'B'

If I create the helper using block help in controller the rails render the currect letter, like this

class AController < ...
  helper { def foo; 'A'; end }
  def index
    render :inline => '<%= foo %>'
  end

class BController < ...
  helper { def foo; 'B'; end }
  def index
    render :inline => '<%= foo %>'
  end
end

/a => 'A'
/b => 'B'

In rails master this works fine.

I attached a patch with failing test in 3-0-stable branch.

Rafael,

This does not work on master either:

$ script/rails g controller a index
$ script/rails g controller b index

routes.rb:

Ticket5565::Application.routes.draw do
  resources :a
  resources :b
end

Helpers:

module AHelper
  def foo
    'A'
  end
end

module BHelper
  def foo
    'B'
  end
end

In both views:

<%= foo %>

http://localhost:3000/a => "B" http://localhost:3000/b => "B"
