ajax problem

Hi,

I am trying to use ajax to update a page by using the link_to command. When I click the link_to commad my ajax request is not being process.

The view is a list of message. Once I click on a message link_to command, I want it to update the message <div>. When I click on the link_to command, I get this respond in the url: http://localhost:3000/mailbox?url[action]=update&remote=true

My javascript is not being render.

Please help. Thanks.

<h2><%=h @folder.name %></h2> <table border="1">   <tr>     <th>From</th>     <th>Subject</th>     <th>Received</th>   </tr>

  <% for message in @messages %>     <tr>       <td><%= message.author.login %></td>       <td><%= link_to message.subject, :url=>{:action=> :update} , :remote => true %></

      <td><%= distance_of_time_in_words(message.created_at, Time.now) %> ago</td>      </tr>   <% end %> </table>

<div id="message">

</div>

<%= will_paginate @messages %>
