Hi all,

I know that I've been sent lots os questions, but before I aways give a
check at documentation and showcase. I hope you can give me a hand.

I want to link two autocompleters. My action is setting the correct secound
list. The problem is that it's never rendered on my jsp.

The objective is to list all cities from a state.

Here's my code:

JSP -----------------------------------
<s:url id="urlListCli" action="listarCidades" namespace="/cliente"/>
<s:action var="actListarUfs" name="listarUfs" namespace="/cliente" />

        <sx:autocompleter list="#actListarUfs.ufs" listKey="cd"
listValue="sigla" label="UF"
            name="siglaUf" id="siglaUf" required="true"
cssClass="autoCompleter" forceValidOption="true"
valueNotifyTopics="/listCidades"/>

        <sx:autocompleter label="Cidade" id="idCidade" name="idCidade"
            list="cidades" listKey="cd" listValue="nome"
            href="%{urlListCli}" autoComplete="true" formId="formCli"
            listenTopics="/listCidades" forceValidOption="true"
preload="false"/>

struts.xml ------------------------------

    <action name="listarCidades" method="listarCidades"
class="br.com.sgvdba.actions.cliente.ClienteAction">
             <result></result>
        </action>

ActionClass -------------------------

    public String listarCidades(){
        this.cidades = getCidadeFacade().recuperarPorUf(siglaUf);
        return Action.SUCCESS;
    }


I also tried to follow the example in show case (linking two
autocompleters), so, on this way I just had success returning a simple array
of string with one dimension, and I thought "ok, I have the correct
description of the field, what about its id?". In this way my action as
returning a .ftl.

Tanks a lot!

Hi all,

I resolved my problem using JSON.
Some links:
http://struts.apache.org/2.x/docs/ajax-and-javascript-recipes.html#AjaxandJavaScriptRecipes-Exampleaction
http://cwiki.apache.org/S2PLUGINS/json-plugin.html

Here's the code (Maybe it could help someone)
Dont forget to include json.jar in your classpath

struts.xml ---------------------------------------
<package name="ajax" extends="json-default">

        <action name="listarCidades"
class="br.com.sgvdba.actions.ajax.CidadesListAction">
            <result type="json" />
        </action>

    </package>

jsp ----------------------------------------------------
<s:action var="actListarUfs" name="listarUfs" namespace="/cliente" />
<s:action var="actListarCidades" name="listarCidades" namespace="/cliente"
/>
<s:url id="urlListCli" action="listarCidades"/>

        <sx:autocompleter list="#actListarUfs.ufs" listKey="cd"
listValue="sigla" label="UF"
            name="siglaUf" id="siglaUf" required="true"
cssClass="autoCompleter" forceValidOption="true"
valueNotifyTopics="/listCidades"/>

        <sx:autocompleter label="Cidade" id="cidades" name="cidades"
            list="cidades" listKey="cd" listValue="nome"
            href="%{urlListCli}" autoComplete="true" formId="formCli"
            listenTopics="/listCidades" forceValidOption="true"
preload="false" cssClass="autoCompleter"/>

action ------------------------------------------------------------
(note that the method's name is: get + the name attribute of your
autocompleter)
public class CidadesListAction extends ActionSupport{

    private static final long serialVersionUID = -5821147861362223337L;
    private String siglaUf;
    private CidadeFacade cidadeFacade;

   public final Map<String, String> getCidades(){

           Map<String, String> cidadesMap = new HashMap<String, String>();
        List<Cidade> cidadesList =
getCidadeFacade().recuperarPorUf(siglaUf);

        for (Iterator<Cidade> it = cidadesList.iterator(); it.hasNext();){
            Cidade cidade = (Cidade) it.next();
            cidadesMap.put(cidade.getNome(), cidade.getCd().toString());
        }
        return cidadesMap;
   }

    /**
     * GETTERS AND SETTERS
     */
    public final String getSiglaUf() {
        return siglaUf;
    }
    public final void setSiglaUf(String siglaUf) {
        this.siglaUf = siglaUf;
    }
    public CidadeFacade getCidadeFacade(){
        if (this.cidadeFacade == null){
            this.cidadeFacade = new CidadeFacade();
        }
        return this.cidadeFacade;
    }

}
