如何从Flash Builder（Flex 3.5）获取比“undefined”更好的信息？

我以前在控制台窗口中看到过所有“未定义”，但我可以弄清楚它的含义。这一次，我在CollectionEvent (super(type, bubbles, cancelable);的构造函数的开始行中找到它）。我认为这是由写入XMLListCollection引发的。似乎没有任何关于它的未定义 - 指针看起来不错，所有参数也都这样。它有一个相当大的堆栈跟踪，但没有关于什么是未定义的有用信息。我如何进入下一个调试步骤？如何从Flash Builder（Flex 3.5）获取比“undefined”更好的信息？

将一个断点UMTAControl.as的79行，然后点击“进入”了很多。要小心检查事物的每一步 – JeffryHouser 2013-04-11 15:25:29

我认为在这种情况下未定义的是实际的错误信息。通常，在堆栈跟踪中，这是错误文本的位置。按照上面的建议，您甚至可以将断点设置为在AddressNode.as第192行的堆栈跟踪中稍高一点虽然这一切看起来都很奇怪，但不确定代码是多么有帮助。 – 2013-04-11 16:48:44

这么多重复的行。某种类型的XML递归......或者“堆栈溢出” ？但是，你很幸运有堆栈跟踪，调试adt崩溃是莫大的再...有趣。 – user1875642 2013-04-11 17:14:01

这是正确的“不确定”的其他情况下都是由于无限递归导致堆栈溢出（即给出了深思熟虑的反馈，而不是那种）。

我想象到这些回调与MFC模型类似，消息排队，只有当应用程序开发人员的代码完成执行时才处理（我认为重复消息有时可能已合并）。很明显，这不是发生了什么 - 正在进行更改，并立即执行回调。我想我将无法可靠地检测更改此XMLListCollection :(

谢谢你们
