JSF 2.2 SelectManyCheck 破坏了 javascript

它曾经在 jsf 2.0 上完美工作，但知道它会在屏幕末尾呈现一个框，其中包含一个包含位置数据的 html 表，如果我删除转换器，则 selectmany 复选框有效，但它仍然呈现该框。

我的转换器：

@FacesConverter(value = "ubicacionConverter")
public class UbicacionesBYOfertasConverter implements Converter {

private FacesContext facesContext = FacesContext.getCurrentInstance();
private OfertaController ofertaController = (OfertaController) facesContext.getApplication()
            .evaluateExpressionGet(facesContext, "#{ofertaController}", OfertaController.class);

@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
    if (value == null) {
        return null;
    }
    System.out.println(value);
    Ubicacion ubicacion = ofertaController.getSelected().getEmpresaidEmpresa().getUbicacionCollection().iterator().next();        
    ofertaController.getSelected().setUbicacionCollection(ofertaController.getSelected().getEmpresaidEmpresa().getUbicacionCollection());
    return ubicacion;

<h:form enctype="multipart/form-data">
