<listbox model="@load(vm.items)" selectedItem="@bind(vm.selectedItem)">
<listhead>
<listheader label="idCaracteristicas"/><listheader label="descricao"/></listhead>
<template name="model" var="item"><listitem value="@load(item)"><listcell><a label="@load(item.idCaracteristicas) @converter('vipconnect.framework.zk.databind.IntegerConverter')" onClick="@command('clickA',item=self.getParent().getParent())"/></listcell><listcell label="@load(item.descricao) "/></listitem></template></listbox>

Hi,

Zk try to find a method like getConverter or method with varArgs in class associated with vm.
My solution was create method getConverter:

    public Converter getConverter(final String name)
            throws InstantiationException, IllegalAccessException,
            ClassNotFoundException {
        System.out.println("BaseService.getConverter() " + name);

        return (Converter) Class.forName(name).newInstance();
    }
