I have this zk code:

<hbox pack="center" align="top" width="100%" height="400px">
<style src="/widgets/combobox/simple_combobox/css/simple_combo.css" />
<div apply="org.zkoss.bind.BindComposer" height="278px" width="443px"
 viewModel="@id('vm') @init('ShirtViewModel')">
    <separator spacing="40px" />
    <hbox>
        <vlayout>
            <separator/>
            <label value="Color" />
            <combobox id="cmbColor" width="150px"
                  model="@load(vm.names)" selectedItem="@bind(vm.iname)">
            </combobox>
        </vlayout>

    </hbox>
</div>
</hbox>

and i have this java class:

public class ShirtViewModel {
    private String iname, iSize;
    private  List<String> names = Arrays.asList("juan", "marcus", "pedro");
    private  List<String> sizes =  Arrays.asList("big", "little", "medium");

    public List<String> getNames() {
        return names;
    }

    public void setNames(List<String> names) {
        this.names = names;
    }

    public void setSizes(List<String> sizes) {
        this.sizes = sizes;
    }

    public List<String> getSizes() {
        return sizes;
    }

    @Init
    public void init() {
        setIname("juan");
        setiSize("big");
    }

    public String getIname() {
        return iname;
    }

    public void setIname(String iname) {
        this.iname = iname;
    }

    public String getiSize() {
        return iSize;
    }

    public void setiSize(String iSize) {
        this.iSize = iSize;
    }
