Facebooker talk - Jun 2008 - Double Frame Problem

The only solution I''ve seen to the problem of the nested frame on the 
login/install pages (when using iframes rather than fbml), is to use JS to cause
a redirect (c.f. 
http://rubyforge.org/pipermail/facebooker-talk/2008-May/000638.html, 
http://webjazz.blogspot.com/2008/03/gotchas-of-internal-iframe-facebook.html):

   def create_new_facebook_session_and_redirect!
     session[:facebook_session] = new_facebook_session
     render :layout => false, :inline => %Q{<script
type="text/javascript">
      top.location.href = "<%= session[:facebook_session].login_url
-%>"
      </script>}
   end

   def application_is_not_installed_by_facebook_user
     render :layout => false, :inline => %Q{<script
type="text/javascript">
      top.location.href = "<%= session[:facebook_session].install_url
-%>"
      </script>}
   end

Has anyone got a more elegant solution? (I think) This approach is messing up my
Selenium tests (as Selenium uses frames and so redirecting "top" has
unwanted
effects).

In hopeful expectation ...
