undefined method `debug_rjs=' for ActionView::Base:Class #1
Description
When I add this to the Gemfile of a fresh Rails 3.1.0.beta1 app and add config.action_view.debug_rjs = true to environments/development.rb I get the following exception:
/gems/actionpack-3.1.0.beta1/lib/action_view/railtie.rb:34:in `send': undefined method `debug_rjs=' for ActionView::Base:Class (NoMethodError)
