我在 Mobile Actionscript Flash Builder 项目中使用 Away3D 框架，并尝试在我的 bb 剧本上调试/运行。当我通过 Flash Builder（不是特定于 bb playbook）运行/调试时，一切都很好。一旦我尝试在我的实际设备上运行/调试，我就会收到以下错误：

TypeError：错误 #1009：无法访问空对象引用的属性或方法。
在 away3d.core.managers::Stage3DManager()[/Users/jesskeating/Documents/Adobe Flash Builder 4.6/3DMobile/src/away3d-core-fp11_4_0_9_gold(1)/src/away3d/core/managers/Stage3DManager.as:35 ]

在 Flash.display::DisplayObjectContainer/addChild() 在 Main/setupScene（[/Users/jesskeating/Documents/Adobe Flash Builder 4.6/3DMobile/src/Main.as:85]

在 Main()[/Users/jesskeating/Documents/Adobe Flash Builder 4.6/3DMobile/src/Main.as:79]

我知道空对象引用意味着我需要声明/定义一个 var 但由于该应用程序与 flash builder 完美运行我不明白。

任何帮助将非常感激。我的代码如下...

我不认为 BB Playbook 的 AIR 版本支持 Stage3D，最后我听说他们使用的是 AIR 3.1。我读到他们计划用 AIR 3.2 或更高版本更新 SDK，但不确定这是否已经发生。
