Facebooker talk - Jun 2008 - how/where to rescue TooManyUserActionCalls on mini feed

Hello,

I''ve a little app up and running, and have only come across this error
a couple of times, but would like to rescue it to be able to fail
gracefully.
Testing to see if this could work would be problematic as once I''ve
hit the limit, I have to wait  a few hours to try again!, so I''m
asking your advice :)

The relevant bits of code is based on:
http://apps.facebook.com/facebooker_tutorial/messaging/mini_feed

my attempt:

   def mini_feed strength
      begin
         @userF = session[:facebook_session].user
         profile_url = "http://www.facebook.com/profile.php?id=" +
@userF.uid
         FacebookPublisher.deliver_mini_feed(facebook_session.user, strength)
      rescue Facebooker::Session::TooManyUserActionCalls
         flash[:notice] = "<p>Whoops, you''ve reached the
limit for
adding news items today, try again tomorrow.<p>"
      else
         flash[:notice] = "<p>Great stuff! a news item with the
results has been added to your mini feed.<p>"
      end
   end

Does this seem ok? Or should I be rescuing it in the
facebook_publisher.rb class, or in the controller method that calls
mini_feed() ?

many thanks!

Tim
