Rails - Nov 2005 - 2 autocomplete fields

I''ve got a problem with these ;]

The second one does not work, does not even request a controller method. 
Acts like a usual field... What do I do wrong?

#view

	<tr>
		<td class="required">Key Account Manager:</td>
		<td class="content">
			<%= text_field_with_auto_complete :user, :last_name, {}, :skip_style 
=> true %>
		</td>
	</tr>
	<tr>
		<td class="head">Parent Account:</td>
		<td class="content">
			<%= text_field_with_auto_complete :account, :name, {}, :skip_style => 
true %>
		</td>
	</tr>

#controller
   def auto_complete_for_user_last_name
   	value = @params[:user][:last_name]
		@users = User.find(:all,
			:conditions => [ ''LOWER(last_name) LIKE ?'',
	    ''%'' + value.downcase + ''%'' ],
	    :order => ''last_name ASC'',
	    :limit => 8)
	  render :partial => ''users''
   end

   def auto_complete_for_account_name
   	value = @params[:account][:name]
		@accounts = Account.find(:all,
			:conditions => [ ''LOWER(name) LIKE ?'',
	    ''%'' + value.downcase + ''%'' ],
	    :order => ''name ASC'',
	    :limit => 8)
	  render :partial => ''accounts''
   end
