Rails - Sep 2007 - Rendering a partial from within that partial

I am having trouble rendering a partial called ''names'' through
a submit
tag located within that partial. The form data is saving with my current
code. However, the existing data is not loading into the form and the
partial is not being re-rendered upon submission to reveal the changes
to this data.What might I do to fix this?

show.rhtml

<%= javascript_include_tag :defaults %>
<ul id="name_list"><%= render :partial =>
''names'', :object => @person
%></ul>


_names.rhml (lists the names of ''Person''. Clicking on a name
reveals a
form to edit that name)

<% for name in @person.current_names %>
<%= link_to_function (name.full_name, :onclick =>
"Element.show(''edit_name_#{claimantname.id}'')"
%><br>
<div id="edit_name_<%= claimantname.id %>"
style="display:none;">
  <%= form_remote_tag(:url => {:action =>
''update_name'', :id => name}
)%>
    <%= text_field ''name'', ''first_name''
%>
    <%= text_field ''name'', ''last_name''
%>
    <%= submit_tag ''Edit'', :onclick =>
"Element.hide(''edit_name_#{name.id}'')"
%></tr>
  <%= end_form_tag %>
</div>
<% end %>


persons_controller

  def update_name
    @name = Name.find(params[:id])
    if @name.update_attributes(params[:name])
      return if request.xhr?
      render :partial => ''names''
    end
  end


update_name.rjs

Code :  ruby - fold - unfold
page.replace_html("name_list", :partial => "names",
:object => @person)

 - There''s no @person instance variable defined by the update_name 
action.
 - text_field ''name'', ''last_name'' assumes
there''s an instance variable
@name, which there isn''t in your case. One way round it is to do this

<% form_remote_for(:name, name, :url => {:action =>
''update_name'', :id
=> name}) do |f| %>
     <%= f.text_field :first_name %>
    ...
<% end %>

Right on about the @person instance variable. form_remote_for used as 
you suggested loads my data into the fields fine:

<% form_remote_for(:name, name, :url => {:action =>
''update_name'', :id
=> name}) do |f| %>
    <%= f.text_field :first_name %>
    <%= f.text_field :last_name %>
    <%= submit_tag ''Edit'' %>
<% end %>

 However, it no longer saves my changes. Is there something I need to 
change in the controller or submit tag as well?

Thanks for your help.
