Hi,
#view <%form_tag :action=>"some_action" do -%> <table> <tr> <td><%=text_field "user","name"-%></td> <td id="name_response"></td> <%=observe_field :user_name,:update=>"name_response",:url=>
You're using form_tag which means that the params hash is not bound to an object. Both your text_field syntax and your observe_field syntax assume otherwise. Make them match. Also, you're headed for nothing but trouble trying to use Ajax on tables. Microsoft controls how tables work. And they don't work well with Ajanx.
HTH, Bill
You're welcome.
