ajax autocompleter

Hi,
I tried to use autocompleter on base of tutorial 
http://www.benmccann.com/dev-blog/struts-2-ajax-tutorial-dojo-autocompleter-example/, 
which do nothing.

My code is:
public class HintAddresses extends ActionSupport{
    private String namePart;
    private Map<Integer,String> json;
    static Logger log = Logger.getLogger(HintAddresses.class);

    public String getAddresses(){
        try{
            log.info("call getAddresses");
            setEnableAjax(new Boolean(true));
            json = new HashMap<Integer,String>();
            ...
            List<Customers> list = instance.findByPartOfName(namePart);
            for(Customers c : list){
                json.put(c.getId(), c.getName()+", "+c.getStreet()+" 
"+c.getZip()+" "+c.getCity());
            }
           
        }
        catch(Exception e){
            log.error(e.getMessage());
            e.printStackTrace();
        }
        return SUCCESS;
    }
...

In struts.xml I have
<package name="ajax" extends="json-default">
          <action name="AutocompleteAddress" 
class="cz.chalu.addresses.HintAddresses">
            <result type="json"><param name="root">json</param></result>
          </action>
    </package>

in base template:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib uri="/tags/c" prefix="c" %>
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>

<html>
<head>
<SCRIPT TYPE="text/javascript" SRC="templates/inc/dojo/dojo.js"></SCRIPT>

  <title><s:property value="getText('application.title')" /></title>
  <link rel="stylesheet" type="text/css" href="templates/inc/styles.css" 
media="screen" />
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 
</head>
...
 <tiles:insertAttribute name="body" />

and in body file:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>

<table>
<tr>
<td><s:text name="simplesearch.bynameorperson"/></td>
<td>
<s:url id="AddressList" action="AutocompleteAddress" 
method="getAddresses" />
<sx:autocompleter name="namePart"  href="{%AddressList}" size="24" />

When I try to type text into autocompleted textfield, nothing happens 
and address is not called (there is logging message)
I am using Struts 2.1.6, struts2-dojo-plugin-2.1.6.jar and 
jsonplugin-0.33.jar are included in lib folder

Where can be problem, what I understand not well?

Thanks
Jiri
