Rails - Apr 2006 - using form_remote_tag and radio_button

I want the user to select a date using radio buttons. The following
code shows the last 7 days.

<%= form_remote_tag(:update => ''register_order'',
                    :url => { :action => :register_orders } ) %>
  <% 1.upto(7) do |i| %>
    <%= radio_button "date", "register_date",
i.days.ago.strftime("%Y-%m-%d") %>
             <%= i.days.ago.strftime("%Y-%m-%d") %>
    <br />
  <% end %>
    <br />
  <%= submit_tag "Register" %>
<%= end_form_tag %>
<div id="register_order"></div>

The controller has:

  def register_orders
    render(:layout => false)
    @date = params[:date][:register_date]
  end

register_orders.rhtml has:

Date:  <%= @date %>

If I comment out render-layout I get the date in
register_orders.rhtml, but also the layout twice. If I activate
render-layout I can get the date by changing register_orders in the
controller to:

  def register_orders
    render(:layout => false)
    render_text params[:date][:register_date]
  end

But then register_orders.rhtml appears unused. Am I missing something?
This is on rails 1.0, webrick, os x.

Turns out that I had to change register_orders in the controller to:

  def register_orders
    #render(:layout => false)
    @date = params[:date][:register_date]
    render :partial => "register_orders"
  end

So render partial solved the problem. Rendering partials also requires
a rename to _register_orders.rhtml.
