Question

它曾经在jsf 2.0上工作得很好但是知道它在屏幕的末尾呈现一个框，带有关于位置数据的html表，如果我删除了转换器的selectmany 复选框有效，但它仍然呈现框。

<ui:composition template="/template.xhtml">

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;
}

@Override
public String getAsString(FacesContext context, UIComponent component,
        Object value) {
    String string = null;
    if (value instanceof Integer) {
        string = String.valueOf(ofertaController.getSelected().getEmpresaidEmpresa().getUbicacionCollection().iterator().next().getIdUbicacion());

inputfile大部分都在这样的其他形式

<h:form enctype="multipart/form-data">                                
                            <p:fileUpload value="#{contratosMB.fileContrato}" mode="simple" />  
                            <p:commandButton value="Cargar Archivo" ajax="false"  
                            actionListener="#{contratosMB.upload}" icon="ui-icon-arrowreturn-1-n"/>  
</h:form>
