Away3D和BB Playbook

Question

I am using Away3D framework inside a Mobile Actionscript Flash Builder project, and trying to debug/run on my bb playbook. When I run/debug through Flash Builder (not bb playbook specific) everything work great. As soon as I try to run/debug on my actual device I get the following error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

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

I know null object reference means I need to declare/define a var but since the app in running perfectly with flash builder I don't understand.

Any help would be much appreciated. My code follows...

I don't think BB Playbook's version of AIR supports Stage3D, last I heard they were using AIR 3.1. I read they were planning on updating the SDK with AIR 3.2 or later, but not sure if that has happened yet or not.
