我是新的Flex和最近读到的验证和失效的部件。可能有人解释一下它的意思时，它的使用，可能会出现一些好文章。

I am new in flex and recently read about Validation and Invalidation in components. May somebody explain what it's mean and when it's use, may be some good article.

推荐答案

我觉得章的关于创建从Adobe的Flex的LiveDocs先进的组件将是一个很好的起点。就拿子章节关于失效办法的通知。

I think the chapter "About creating advanced components" from the Adobe Flex LiveDocs will be a good starting point. Take notice of the subchapter "About the invalidation methods".
