[away3d] ObjectContainer3D.cloneAll(),then Return Object3D.name?

[rayYee]

code:
loaderhair = Collada.parse(hai,{material:mm});
var hair:Object3D=loaderhair.cloneAll()
//   hair.name? is null
//   then
basic.addChild(hair)
if (basic.getChildByName("obj_Bhair-node")){
basic.removeChildByName("obj_Bhair-node")
}
I hope remove the hair:Object3D
