I''m having a bit of a headbanger here... maybe someone can help. A class in a fairly complicated existing Rails app that I''m working on seems intermittently not to load. The error is basically the following: undefined class/module InnerPackage c:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.0 /lib/action_controller/session/active_record_store.rb:75:in `load'' c:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.0 /lib/action_controller/session/active_record_store.rb:75:in `unmarshal'' c:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.0 /lib/action_controller/session/active_record_store.rb:116:in `data'' c:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.11.0 /lib/action_controller/session/active_record_store.rb:126:in `marshal_data!'' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.0 /lib/active_record/callbacks.rb:333:in `send'' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.0 /lib/active_record/callbacks.rb:333:in `callback'' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.0 /lib/active_record/callbacks.rb:330:in `each'' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.0 /lib/active_record/callbacks.rb:330:in `callback'' c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.13.0 /lib/active_record/callbacks.rb:248:in `create_or_update'' <snip> I''ve seen this happen if the controller file has a syntax error, but that''s not it. I''m interested mostly hearing a debugging approach that I haven''t tried, or if you''ve banged your head on this one before, what you learned in doing so. The model file is in app_root/app/models The problem is intermittent, and goes away for a while if I restart WEBrick _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
