maybe this will help others who have run into issues relating to calling properties on objects that are null when the Collada file is being parsed.
I spent a few hours figuring out what I had to do to get a basic Collada file that I exported from a Blender file to render in Away3DLite. I was getting null warnings until I made sure that the object I was exporting from Blender had: a. a Material (go to the Buttons Window,click Materials Buttons, click 'add new') b. a UV texture (use 'u' shortcut key when cursor is in 3d viewport and select any of the unwrap options - you will see it listed in the Editing Panel(F9) and also in the UV Editor window when the selected mesh is in Edit mode (tab key)) c. at least 1 keyframe in order to contain animation data (primitives added in 2.49 seem to possess animation data by default but in 2.50 beta I had to insert a keyframe using 'i' shortcut in 3d viewport) I haven't tried an animated object yet and only tried with Blender primitives. Using Collada 1.4 in 2.49, the single Collada export option in 2.50beta and Away3DLite 1.0.4.
