ActiveRecord::Observer.observed_classes doesn't get redefined properly
Reported by Grant Hutchins | April 18th, 2011 @ 07:20 PM
class Foo < ActiveRecord::Base
end
class BarObserver < ActiveRecord::Observer
observe :foo
end
ruby-1.8.7-p174 > BarObserver.observed_classes
NameError: uninitialized constant Bar

By reading the implementation at https://github.com/rails/rails/blob/v3.0.6/activemodel/lib/active_m... I would expect BarObserver's observed_classes method to have been redefined to return [Foo] without trying to find the non-existant Bar class.
