Forms 无法将值从一个复合组件复制到另一个JSF

我在尝试跨组件获取值时感到非常沮丧。 我正在尝试做一个我可以重用的地址组件，一次用于住宅地址，一次用于邮政地址。有一个SelectOne复选框，允许用户指定居住地址与邮政地址相同。我希望将第一个住宅地址组件的值复制到第二个邮政地址组件的值，然后禁用第二个组件

我已经尽我最大的努力让我的要求尽可能的让人理解，我希望你们能理解我的要求。请帮帮我。

在布尔值复选框的值更改侦听器中，您必须填充您未执行的邮政地址对象。如果邮寄地址和居住地址都是同一类型的地址，那么你必须这样做

希望这会有所帮助。

问题是我没有完全理解JSF生命周期，我在应用请求值阶段而不是调用应用程序阶段更新我的值。另外，将邮政地址设置为与住宅地址相同的对象是一个坏主意，因为这样一来，我就无法更新其中一个而不影响另一个

在值更改侦听器中，您必须填充postalAddress对象。如果邮政地址和居住地址都是同一类型的地址，那么您可以这样做谢谢Srikanth Ganji，您的回答有点帮助，但不完全正确。我将发布我的答案，以便您也可以确保它。
