https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/2999 I''ve submitted a patch for this bug that raises an exception anytime there is an Array in the request parameters with Ruby 1.9. I''d appreciate if one of the core members could check it out and apply it. Thanks, Brandon -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
