<w:menu id="format" label="格式"> 
  <w:radioMenuItem value="#{MenuBean.color}" valueChangeListener="#{MenuBean.radioValueChanged}"> 
    <f:selectItems value="#{MenuBean.colors}"/> 
  </w:radioMenuItem> 
</w:menu>

在菜单中显示一组颜色选择的菜单项，当用户改变颜色选择时，通知#{MenuBean.radioValueChanged}对应的方法。它的Managed Bean部分代码如下：

public class MenuBean { 

  .... 

  public enum COLOR { RED, GREEN, BLUE }; 
  private COLOR color = COLOR.RED; 

  public COLOR getColor() { 
    return color; 
  } 

  public void setColor(COLOR color) { 
    this.color = color; 
  } 

  public SelectItem[] getColors() { 
    return new SelectItem[] { 
      new SelectItem(COLOR.RED, "Red"), 
      new SelectItem(COLOR.GREEN, "Green"), 
      new SelectItem(COLOR.BLUE, "Blue") 
    }; 
  }

   .... 
}
