Hi, I have a problem with Rails 0.14.3. I have an application which uses 2 databases : oracle and postgresql. I can connect to the both databases and use them. The application works correctly (I can reach the controllers, add records in the databases without errors) but during or after a redirection I receive an error. I check with breakpoint and the log, I see in the log : "Redirected to http://localhost:3000/result" and just after the error message : /TypeError in Invoice#index can''t convert String into Integer RAILS_ROOT : script/../config/.. /usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/rescue:75:in ''[]='' ///usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/rescue:75:in ''rescue_action_locally'' /usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/rescue:31:in ''rescue_action'' /usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/rescue:108:in ''perform_action'' /usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/base.rb:365: in ''process_without_session_management_support'' /usr/local/lib/ruby/gem/1.8/gems/actionpack-1.11.0/lib/action_controller/session_management.rb:116:in ''process'' .... /In the error message, there is no line of my code, just files from rails (actionpack, rails or webrick) Did somebody already meet this error or has an idea to solve it ? Thanks in advance Gael
