I tried to just change the rails gem I use with my application and I got the following error: /usr/local/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/ active_support/core_ext/module/aliasing.rb:33:in `alias_method': undefined method `template_exists?' for class `ActionController::Base' (NameError) I can create a new project and it starts fine. Where is this error coming from? Are there certain steps to migrate from 2.2.2 to 2.3.2? Don F.

Hi Don, This document helped me to migrate from 2.1 to 2.3: http://guides.rubyonrails.org/2_3_release_notes.html I also found a Google search on 'rails 2.3 <error message>' very useful. CmdJohnson
