Question

我想编写一个能够输入地址的compositeComponent。另外我想在提交时做一些验证，如果验证失败，我想重新渲染复合组件的一部分。我真的不知道如何改善这一点。我的想法是在getConvertedValue方法中进行验证，只需设置标志并在验证失败时抛出validatorException。

我已经在balusC的博客上阅读了很多关于复合材料组件的内容，但是找不到合适的方法来提供我想要的东西。

这是我的代码到目前为止：的 addressInput：

        throw new ValidatorException(new FacesMessage());

        // Otherwise just return the value.

        // return submittedValue;

}

组件应该像这样工作：输入位置=＆gt;按保存（组件外部）=＆gt;检查位置是否可编码（通过webservice）=＆gt;如果是，请返回该位置，否则检查是否有任何建议或地址是否不可编码=＆gt;如果不可编码，请创建一个复选框，您可以勾选＆＃34;忽略＆＃34;并返回位置。

谢谢！
