Rails - Sep 2010 - Rails3: jquery-rails gem sets 'config.action_view.javascript_expansions' but cannot be overriden in 'config/application.rb'

Hello,

I''ve created a new Rails3 app and I''m using jQuery instead of
prototype.

Gemfile:
gem ''jquery-rails''

in my config/application.rb I want do the following:

config/application.rb
if Rails.env.production?
     config.action_view.javascript_expansions[:defaults] = %w(jquery.min
rails application)
else
     config.action_view.javascript_expansions[:defaults] = %w(jquery rails
application)
end

So in production I want to include jquery.min whereas in development I want
the unminified (jquery).

But this seems not to work and when I look at the jquery-rails railtie, I
see the following code:

module Jquery
  module Rails
    class Railtie < ::Rails::Railtie
      config.before_initialize do
        if
::Rails.root.join("public/javascripts/jquery-ui.min.js").exist?
          config.action_view.javascript_expansions[:defaults] %w(jquery.min
jquery-ui.min rails)
        else
          config.action_view.javascript_expansions[:defaults] %w(jquery.min
rails)
        end
      end
    end
  end
end

This sets the config.action_view.javascript_expansions[:defaults] to
always use jquery.min.  So it seems to me that the code from my app
(config/application.rb) isn''t applied. Although this should be
possible to do.

Is this expected behavior? Shouldn''t it be possible to override the
expansions in your own application?

TIA

C+++
