Hi, I saw a previous post from David answering someones question about fixture_scenarios with rspec. Following that I upgraded my rspec and rspec_on_rails to the trunk versions and then installed the fixture scenario plugin. Now whenever I run my (previously passing rspecs) I get the following error for all tests... ... 148) NoMethodError in ''Cart should show a sub_total_amount'' You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each ../vendor/plugins/fixture_scenarios/lib/fixture_scenarios.rb:37:in `create_fixtures'' ../vendor/plugins/fixture_scenarios/lib/fixture_scenarios.rb:33:in `create_fixtures'' ../vendor/plugins/fixture_scenarios/lib/fixture_scenarios.rb:26:in `create_fixtures'' ../vendor/plugins/fixture_scenarios/lib/fixture_scenarios.rb:257:in `load_fixtures'' ../vendor/plugins/rspec_on_rails/lib/spec/rails/dsl/behaviour/ rails_example.rb:27:in `before_eval'' At the moment I am only using global fixtures for one model, I have tried removing this line and its still the same error. config.global_fixtures = :sites and I have added the trailing slash to my fixture path config.fixture_path = RAILS_ROOT + ''/spec/fixtures/'' Anyone got any pointers on getting this running? This particular application uses railsengines (both rails and engines are gem versions of 1.2 (rails 1.2.3)) Thanks, David
