In all our engines, the app/controllers/*_controller.rb are read twice during application startup, resulting in undesirable side effects, such as duplicated before and after filters. We have post a ticket in the Rails Engine tracking system [1], but we are doubting if it is also reasonable to post it in Rails Trac, because, althought de engine has its own controllers, filters are Rails features. The question is: who causes the filters be read twice? [1] http://dev.rails-engines.org/tickets/177 -- Fernando Blat blog > http://www.tabernadelturco.com
