Filter run twice with sub classes

class User::Signin::BaseController < User::BaseController

before_filter :before_filter_setup_user
def before_filter_setup_user
puts “hi”
end

def index
end

end

class User::Signin::BasicController < User::Signin::BaseController

def index
end

end

The filter gets called twice, “hi” prints twice, what is the best way
to prevent this?
