Im using zk 2.4.1 and my zul is:

<a:bind model="classificacoesCliente"
selectedItem="clienteBean.TClassificacaoCliente" /> <listbox id="cmb_classificacao" mold="select" rows="1" >
<a:bind _var="objClassificacao"/>
<listitem label="@{objClassificacao.nome}" value="@{objClassificacao}"
/>
</listbox>

The itens are shown correctly, but in java when I try to read them:

for (int i=0;i<lst.getChildren().size();i++) {
Listitem lstItem = (Listitem)lst.getChildren().get(i);
System.out.println( lstItem.getLabel() + " - " + lstItem.getValue() ); }

The Label is empty and the value is null.

I tried:
<a:bind _var="objClassificacao" label="objClassificacao.nome"
value="objClassificacao" />
<listitem />

The DataBinder helps you setup the "model" property of the cmb_classificacao Listbox and that is all.

The "label" and "value" is not loaded until the original "live data" mechanism start to work. That is, the data is not loaded into Listitem yet so you get null value and empty label.

It can be verified easily. Prepare a <button> and put your "for loop code" in onClick event listener and you will see the differences.
