[away3d] Away3dLite- issue on null object reference

[Guha]

I am trying to create the 3D layout in MXML using the code below and I
get an error
Error #1009: Cannot access a property or method of a null object
reference.
        at A3DL_Primitives/appComplete()[C:\Documents and Settings\guha\Adobe
Flash Builder 4\testing3dlite\src\A3DL_Primitives.mxml:40]
        at A3DL_Primitives/
___A3DL_Primitives_Application1_applicationComplete()[C:\Documents and
Settings\guha\Adobe Flash Builder 4\testing3dlite\src
\A3DL_Primitives.mxml:8]


I suspect this must be because view(line40) and scene are not
recognized for the base screen- not clear where I am going wrong-
appreciate insights
