Rails - May 2010 - RJS - ActionView::TemplateError (page)

Without going into too much detail, is there something obvious that I''m
missing here?  It seems to be finding the RJS file as expected but
generates this error:

ActionView::TemplateError (undefined local variable or method `page''
for
#<ActionView::Base:0x7f202a04>) on line #1 of
app/views/fuelings/index.js.rjs:
1: page.toggle ''fuelings''

    app/views/fuelings/index.js.rjs:1:in
`_run_rjs_app47views47fuelings47index46js46rjs''
    app/views/fuelings/index.js.rjs:1:in
`_run_rjs_app47views47fuelings47index46js46rjs''
    app/controllers/fuelings_controller.rb:6:in `index''

The general outline (without posting too much code) is:
1) Index action in the controller has a respond_to that invokes
index.js.rjs
2) The index view has an observe that triggers when the select changes
3) The RJS renders a partial (not implemented yet)

Also set up a skeleton rails app just to test RJS and am getting the
same thing when I try any RJS tests.


=========================Controller:

class FuelingsController < ApplicationController
    def index
    @vehicles = Vehicle.find(:all)
      @vehicle = params[:vehicle_id] ?
Vehicle.find_by_id(params[:vehicle_id]) : Vehicle.find(:first)
        @fuelings = @vehicle.fuelings.paginate(:all,:per_page => 15,
:page => params[:page])
    respond_to do |format|
      format.html
      format.js
    end
    end

=========================View:

<% javascript :defaults %>
<% title "Fuelings for: #{@vehicle.license}" %>
<% form_tag "", :url => fuelings_path, :method => :get do
%>
<%= select_tag
"vehicle_id",options_for_select(@vehicles.collect{|v|[v.license,v.id]},@vehicle.id)
%>
<%= observe_field("vehicle_id",
:url => { :action => :index },
:method => :get,
:with => ''vehicle_id'',
:on => "changed") %>
<% end %>
<div id="fuelings">
  <%= render :partial => "fuelings" %>
</div>
<%= will_paginate @fuelings %>

=========================RJS: (just to test)
page.toggle "fuelings"

The only thing that jumps out at me is the lack of a block after your
format...

Try adding it:  format.js {}

If that doesn''t work, add try getting rid of the rjs template for now
and
just render from the contoller.  Generally speaking, that''s preferable
for a
one-liner anyway.

format.js {
  render :update do |page|
     page.toggle ''fuelings''
  end
}

HTH,
Bill
