[away3d] Away3DLite: Bug in the setter of Sphere.segmentsW ?

[ABA]

Hi,

I've a problem with a sphere defined like that :
  var mySphere:Sphere = new Sphere(new BitmapFileMaterial("assets/
texture.jpg"), 1000);
  mySphere.sortFaces = true;
  scene.addChild(mySphere);

Later, depending on the distance between the sphere and the camera I
try to change mySphere.segmentsW and mySphere.segmentsH but there is
the following error:

ArgumentError: Error #2004: L'un des paramètres n'est pas valide.

I've tried tu use Away3DLite 1.0.0 and the trunk with the last version
of Away3DLite but the same error occurs.

Is there a bug or should I realize the modification of the geometry
using an other way ?

Regards.
