[away3d] Phong z-sorting rendering error in 2.2 & 2.3

[Ralph B]

If you apply a phong material to an Away3D primitive object, the
object renders in front of all other objects even if it is behind
those objects.  It renders OK in Away3D 2.1, but not in 2.2 and 2.2.

Has anyone noticed this, or is there a new way to use phong materials
that I missed?
Thanks!
Ralph

Sample code follows:

//var mat:ShadingColorMaterial = new ShadingColorMaterial
(0xFFFFFF);  // Renders correctly
var mat:PhongColorMaterial = new PhongColorMaterial(0xFFFFFF); //
Cylinder appears in front of Trident
//var mat:PhongBitmapMaterial = new PhongBitmapMaterial(new BitmapData
(1, 1, false, 0xFFFFFF )); // Same problem
var cyl:Cylinder = new Cylinder();
cyl.material = mat;
cyl.x = -100; cyl.z = -100;

var trident:Trident = new Trident();
view.scene.addChildren(cyl, trident);

var light:DirectionalLight3D;
light = new DirectionalLight3D({color:0xFFFFFF, ambient:0.2, diffuse:.
5, specular:0.25});
light.x = 6000; light.z = -6000; light.y = 9000;
view.scene.addChild(light);
view.camera.moveTo(2000, 2000, 2000); // Away3D 2.2 & 2.3 syntax
view.camera.lookAt(new Number3D(0, 0, 0));
view.camera.zoom = 20;
view.renderer = Renderer.CORRECT_Z_ORDER;
view.render();
