replace_html help

Hi

     I have a partial file _view_sd_resolution_details.rhtml..In that
file i call link_to_remote as

<table border="0" width="100%">
<tr>
  <td class="itillink1">
    <%= link_to_remote "Edit Resolution",
                            :update => "create_sd_resolution_ui",
                            :url => {:action =>
:define_sd_resolution_ui,
                                :sd_resolution => @sd_resolution_id,
                                :id => @sd_ticket} %>
  </td>
</tr>
</table>

Then in my controller action

def define_sd_resolution_ui
    @sd_resolution_id=params[:sd_resolution]
    @sd_ticket=ServiceDeskTicket.find(params[:id])
    @sd_resolution=@sd_ticket.service_desk_resolution
        render :action => "define_sd_resolution_ui.rjs", :layout =>
false

  end

In define_sd_resolution_ui.rjs

page.replace_html "create_sd_resolution_ui", :partial =>
'define_sd_resolution_ui', :object => @sd_resolution

The partial file _define_sd_resolution_ui.rhtml is to be loaded ..That
is my intention..But it is not working..Please help

Sijo
