jsf - 如何在 JSF 中动态向 SelectOneListbox 添加值

Question

我想在 JSF（Primefaces）中动态创建一个 SelectOnListBox，但我不知道如何用“Verde”和“Azul”填写值

    FacesContext fCtx = FacesContext.getCurrentInstance();
    ELContext elCtx = fCtx.getELContext();
    ExpressionFactory ef = fCtx.getApplication().getExpressionFactory();
            
    getL_valores().put("Verde", "Verde");
    getL_valores().put("Azul", "Azul");
    
    
    javax.faces.component.html.HtmlSelectOneListbox lista = new  javax.faces.component.html.HtmlSelectOneListbox();
    lista.setRendererType("javax.faces.Listbox");
    lista.setId("variacion1");
    
   
    lista.setValue(getL_valores());
    lista.setLabel("lista1");
    
    dynamicFieldGroup = new HtmlPanelGrid();
    dynamicFieldGroup.setColumns(4);
    
    dynamicFieldGroup.getChildren().add(lista);        
    

这是我的 xhtml

 <h:form id="Form1">
        <p:panelGrid columns="2" binding="#{b_detalle_productos.dynamicFieldGroup}"></p:panelGrid>
        
    </h:form>
