Rails - Mar 2006 - render_to_string troubles

Hi,
I''m trying to build a simple mechanism for pre-caching a bunch of files
by iterating over a hash of options from within a controller:

#site.controller:

    for options in [
      { :controller => "site", :action => "welcome" },
      { :controller => "site", :action => "about" },
      { :controller => "site", :action => "contact" },
      { :controller => "site", :action => "funding" },
      { :controller => "site", :action => "funding",
:params => { ''page'' => "proposal.html" } },
      { :controller => "site", :action => "funding",
:params => { ''page'' => "submissions.html" } },
      { :controller => "site", :action => "funding",
:params => { ''page'' => "production.html" } }
    ] do
      rebuild_page(options)
    end

with the following in the application.rb controller:

  # handle all regeneration of pages - available to all controllers
  def rebuild_page(options, path = nil)

    # get rid of the existing one
    expire_page(options)

    # pull the page in as a string
    # set page parameters first:
    if options.has_key?(:params)
      options[:params].each_pair {
        |key, value|
        @params[key] = value
      }
    end
    page = render_to_string(options)

    # write the rendered content to the right place
    cache_page(page, options)

  end


I can see the parameters have been set, but somehow the ''page''
parameter never gets processed by the funding action, so I end up with a 4 pages
that all have the same content (the simple funding page). My
''funding'' action also has a bunch of other @vars which seem to
not be available when rendering the template.

I presumed that the render_to_string method would process the :action with all
available parameters, but I can''t make it do so - am I doing it wrong?
