Flex中的Papervision3D在单击3D对象时抛出错误

Question

我正在做一个游戏，其中有几个平面对象，玩家可以点击。我的主应用程序类扩展了BasicView类。我把整个游戏做成了一个ActionScript项目，当我把它作为一个整体来运行时，一切都运行得很好。

现在我将该游戏加载到Flex应用程序中。当添加到Flex应用程序中时，它可以完美地运行，直到我单击某个位置时，它会抛出以下错误：

有什么办法解决这个问题吗？

在org\papervision3d\core\utils\InteractiveSceneManager.as:189附近有一个if语句，我不得不对其进行注释，然后它就开始工作了。
