SelectManyListbox : How to set the value in the bean ?

Question

Hi,
How can I set the selected values from a selectManyListbox in the bean ?
My page:
                    <li>
                         <div class="box_multiple_selects clearfix">
                              <div>
                                   <span>Esportes Selecionados</span>
                                   <h:selectManyListbox id="esportes_selecionados" size="10" value="artigoDetailsBean.esportes"/>
                              </div>
                              <div class="btns_fluxo fl">
                                   <button value="<<" name="all_right_hand">>></button>
                                   <button value=">" name="one_right_hand">></button>                                   
                                   <button value="<" name="one_left_hand"><</button>
                                   <button value="<<" name="all_left_hand"><<</button>
                              </div>
                              <div>
                                   <span>Esportes Cadastrados</span>
                                   <h:selectManyListbox id="esportes_cadastrados" size="10">
                                        <f:selectItems value="#{artigoDetailsBean.esporteList}" />
                                   </h:selectManyListbox>
                              </div>
                         </div>
                    </li>
"It´s a move right-left panel". In the right listbox are the database data, and the user click in the left arrow to move the elements (options) from right listbox to the left, and I´d like to get the selected values from the left listbox.
The bean:
public class ArtigoDetailsBean {
private Collection<String> esportes;
     public Collection<String> getEsportes() {
          return esportes;
     public void setEsportes(Collection<String> esportes) {
          this.esportes = esportes;
     public List<SelectItem> getEsporteList() {
          List<SelectItem> esportes = new ArrayList<SelectItem>();
          for(Object esporte: artigoDetailsCommand.getEsporteList() ) {
               esportes.add( new SelectItem( ((EsporteVO)esporte).getId().toString(), ((EsporteVO)esporte).getDescricao() ) );
          return esportes;
Thanks in advance,

This blog shows an example of what you are trying to do - when the user clicks the left arrow it triggers an action event that puts the value into the left list, and vice-versa:

Ignore the 'JSF 2.0' in the header - it's not JSF 2.0 in this example!
Also - don't post your email address on the forums - you might get spammed :)
