Uma,
I just checked my app. I am adding a single Geometry to my Shape3D, but
when I call 'numGeometries()' it returns 2. The two geometries returned
using 'getGeometry(int)' are reported as 'null' and the geometry I added
respectively.
I assume that you are aware of this part of the problem ? It is unclear from
your
notes whether you know that the no-params 'addGeometry()' is behaving in
this manner.
Thanks
Rob
