Using the JSF converter in h: selectOneMenu results in a validation error: value is invalid

I have this SelectOneMenu:

<h:selectOneMenu value="#{orderController.requestVO.requestSituation}">
    <f:converter converterId="ComboConverter"/>
    <f:selectItems value="#{orderController.requestSituation}" var="requestSituation"
                                                   itemLabel="#{requestSituation.description}" itemValue="#{requestSituation}" />
</h:selectOneMenu>

requestSituationis ArrayListfilled RequestSituationVO It is filled correctly by generating this HTML:

<select name="j_idt14:j_idt20" size="1">
        <option value="13">Pedido Recusado</option>
    <option value="11">Pedido Validado</option>
    <option value="12" selected="selected">Pedido Confirmado</option>
    <option value="12" selected="selected">Pedido Faturado</option>
</select>

I have it Converter, and that's where I got confused, I read a lot, and I know what it should do, but not how it works.

There he is:

@FacesConverter(value = "ComboConverter", forClass = RequestSituationVO.class)
public class ComboConverter implements Converter
{

    private static RequestSituationVO requestSituationVO = new RequestSituationVO();

    @Override
    public Object getAsObject(FacesContext context, UIComponent component, String value)
    {
        requestSituationVO.setId(Integer.valueOf(value));
        requestSituationVO = (RequestSituationVO) new RequestSituationBO().getRequestSituation(requestSituationVO).toArray()[0];
        return (RequestSituationVO) requestSituationVO;
    }

    @Override
    public String getAsString(FacesContext context, UIComponent component, Object value)
    {
        requestSituationVO = (RequestSituationVO) value;
        String teste = String.valueOf(requestSituationVO.getId());
        return teste;
    }
}

When I submit my page, I think it SelectOneMenuwill automatically set the value for the method requestSituationfrom requestVO. But when I send a message, I get a message Value not validthat refers to mine SelectOneMenu.

I need to set the selected value to mine RequestSituationVOso that I can send it to the Business method.
