Flash Error #1063 Argument count mismatch

I'm getting the开发者_StackOverflow社区 following strange error:

ArgumentError: Error #1063: Argument count mismatch on Away3DLiteSprite(). Expected 4, got 0.

It sounds like you're calling Away3DLiteSprite() without providing any parameters. Locate where in your code that function is being called and make sure you pass in the flarManager, viewportWidth, viewportHeight and stage parameters.
