Empty validation error messages?

Hello,

I'm have a form and the error messages are not being displayed properly

I got a remote_form_for and am trying to show errors like I always do:
<%= error_messages_for @user%>

but the output is:
4 errors prohibited this user from being saved

There were problems with the following fields:

    * {{attribute}} {{message}}
    * {{attribute}} {{message}}
    * {{attribute}} {{message}}
    * {{attribute}} {{message}}

When I use this method, the errors are being displayed correctly:
<% for error in @user.errors %>
  <%= '<font style="color:red">'+error[0]+' - '+error[1]+'</font><br>'
%>
<% end %>

Does anyone know why the error_messages_for does not work?

Sorry, pasted the wrong line. It's this:
<%= error_messages_for :user %>
