Rails - Sep 2006 - ApplicationHelper is not a parent of SomeHelper?

i have:

# file application_helper.rb
module ApplicationHelper
  def load_components
    @right_sidebar = ''some stuffs''
  end
end

# file user_public/blog_helper.rb
module UserPublic::BlogHelper
  def load_components
    ApplicationHelper.load_components
    @right_sidebar += ''{blog archive}''
  end
end

the problem is, i want to load the ApplicationHelper.load_components 
method from the BlogHelper.load_components method -- but apperently the 
application helper is not the root of the blog helper. so how can i 
access it?
thanks in advance

You can use ''super'':

   module UserPublic::BlogHelper
     def load_components
       super
       @right_sidebar += ''{blog archive}''
     end
   end

super searches the object''s method lookup-path for the next-found
method with the same one as the one that''s being executed.  In this
case, it will find the load_components defined in ApplicationHelper.
