“边框厚度”仅受光环主题支持” Flex 命名空间警告
自从我升级到 flash builder 4 以来，我试图了解我的命名空间发生了什么。
应用程序中的 xmlns:mx="http://www.adobe.com/2006/mxml"
在样式表中：
@namespace mx "library://ns.adobe.com/flex/mx";
一切似乎都被正确识别，但是，我收到一条警告：
“borderThickness”仅受光环主题支持
（我认为是在 mx 主题中）。
现在，当我尝试 xmlns:s="library://ns.adobe.com/flex/mx" 时，它无法识别任何内容。我在这里可能做错了什么或令人困惑吗？
I'm trying to understand what is going on with my namespaces since I upgraded to flash builder 4.
xmlns:mx="http://www.adobe.com/2006/mxml" in the application
and in the stylesheets:
@namespace mx "library://ns.adobe.com/flex/mx";
Everything seems to be recognized correctly, however, I get a warning that says:
"borderThickness" is only supported by the halo theme
(which I thought was in the mx theme).
Now, when I try xmlns:s="library://ns.adobe.com/flex/mx" then it doesn't recognize anything. Is there something I might be doing wrong here or confusing?

mx 是 mx 组件的默认前缀 - 它们是您从 Flex 3 开始使用的组件。它的 URI 应该是library://ns.adobe.com/flex/mx
s 是 Spark 组件的默认前缀。它们是flex 4中添加的新组件。它的URI应该是library://ns.adobe.com/flex/spark

mx is the default prefix for mx components - they're the components you're used to from flex 3. it's URI should be library://ns.adobe.com/flex/mx
s is the default prefix for spark components. They're the new components added in flex 4. It's URI should be library://ns.adobe.com/flex/spark

如上所述，您需要确保将 mxml 文件中的 ns 声明更改为：
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:mx="library://ns .adobe.com/flex/mx"
xmlns:s="library://ns.adobe.com/flex/spark"
话虽如此，我已经注意到当您第一次将这些命名空间添加到最初在 FB3 中构建的文件中时，FB4 会有些奇怪。有时它不会对一些旧的光环组件进行代码完成。在我的上，它会神秘地创建一个我什至没有声明的虚构的“mx1”命名空间。大多数时候，我发现关闭编辑器窗口并清理项目，然后重新打开文件似乎可以解决问题。
as quoo stated above, you need to make sure you change the ns declarations in your mxml files to:
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:s="library://ns.adobe.com/flex/spark"
That being said however, I have noticed some wonkiness with FB4 when you add these namespaces for the first time to a file that was originally built in FB3. Sometimes it will not code-complete some old halo components. On mine, it will mysteriously create a fictitious "mx1" namespace that I haven't even declared. Most times I've found that closing the editor window and doing a project clean, then re-opening the file seems to fix the problem.
