[away3d] PathAlignModifier / duplicateMesh() doesn't clone vertices?

[Casey]

I'm trying to align objects other than TextField3D to a path using
PathAlignModifier, but the loops in the execute() method are
contingent upon the vertices of the faces in the _originalMesh.
However, these vertices aren't cloned when the face is cloned.

I was able to get this to work by altering the duplicateMesh() method
(see below), but I'm not exactly sure if this is the best solution.
Please advise!

Thanks,

Casey


BEFORE =======================================

private function duplicateMesh(mesh:Mesh):void
{
        _activeMesh = mesh;

        _originalMesh = new Mesh();
        for each(var face:Face in mesh.faces)
        {
                _originalMesh.addFace(face.clone());
        }
}

AFTER =======================================

private function duplicateMesh(mesh:Mesh):void
{
        _activeMesh = mesh;

        _originalMesh = new Mesh();
        for each(var face:Face in mesh.faces)
        {
                //duplicate the vertices
                var clone:Face = face.clone();
                clone.v0 = face.v0.clone();
                clone.v1 = face.v1.clone();
                clone.v2 = face.v2.clone();

                _originalMesh.addFace(clone);
        }
}
