我在全屏模式下遇到Flash 9播放器问题。在我的情况下,显示DisplayObject行为的addChild方法,同时显示“按Esc退出全屏模式”。在正常阶段模式或“按Esc ..”消息淡出后没有问题。 Flash 10播放器没有这个问题。

我正在尝试使用addChild方法创建新按钮并将其添加到body VBox,并在附加调试器时在下一个Flex显示验证时获取运行时错误;没有调试器全屏只退出和应用程序处于不可用状态(鼠标不工作)。当显示“Esc”消息时按“添加”按钮时会发生这种情况。
发生错误时,调试器会显示该子项为mx.skins.halo.HaloBorder。在没有错误的情况下,child是mx.controls.Button。
错误:
TypeError: Error #1034: Type Coercion failed: cannot convert mx.skins.halo::HaloBorder@19c9869 to mx.core.IUIComponent.

任何人都知道如何解决此问题或为什么会发生这种情况?
