Papervision3D in Flex throws an error when a 3D object is clicked

Question

I am working on a game in which there are several Plane objects that the player can click. My main application class extends the BasicView class. I made this whole game as an ActionScript project and everything works fine when I run it as one.

Now I load this game in a Flex application. When added to the Flex application, it runs perfectly until I click somewhere at which point it throws the following error:

Any ideas on how to fix this?

Answer 1

There was an if statement near org\papervision3d\core\utils\InteractiveSceneManager.as:189 which I had to comment and then it started working.
