Hi, I''m seeing a strange error when I use validates_presence_of with a date attribute validates_presence_of :closing_date, :user, :product When I remove :closing_date it works fine. The stack trace and error is as follows: ArgumentError in BuyController#home wrong number of arguments (1 for 0) C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/callbacks.rb:328:in `notify'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/callbacks.rb:328:in `callback'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/callbacks.rb:308:in `valid?'' #{RAILS_ROOT}/app/controllers/buy_controller.rb:17:in `home'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/base.rb:910:in `perform_action_without_filters'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/filters.rb:368:in `perform_action_without_benchmark'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/benchmarking.rb:69:in `perform_action_without_rescue'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/benchmark.rb:293:in `measure'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/benchmarking.rb:69:in `perform_action_without_rescue'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/rescue.rb:82:in `perform_action'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/base.rb:381:in `process_without_filters'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/filters.rb:377:in `process_without_session_management_support'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.1/lib/action_controller/session_management.rb:117:in `process'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/dispatcher.rb:38:in `dispatch'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/webrick_server.rb:115:in `handle_dispatch'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/webrick_server.rb:81:in `service'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/httpserver.rb:104:in `service'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/httpserver.rb:65:in `run'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:173:in `start_thread'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:162:in `start_thread'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:95:in `start'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:92:in `start'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:23:in `start'' C:/cengal/apps/InstantRails/ruby/lib/ruby/1.8/webrick/server.rb:82:in `start'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/webrick_server.rb:67:in `dispatch'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/commands/servers/webrick.rb:59 C:/cengal/apps/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:147:in `require'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/commands/server.rb:30 C:/cengal/apps/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'' C:/cengal/apps/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:147:in `require'' script/server:3 -e:4 Any thoughts?
