Not necessarily. if you do class Foo include ActionView::Helpers::FormHelper end then f = Foo.new f.instantiate_builder then self in instantiate_builder is f. Whether or not other modules in ActionView::Helpers have been included in Foo is not guaranteed (in the particular case of view helpers in views then all the other submodules of ActionView::Helpers would normally have been included) Fred -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
