[away3d] object3d as Mesh problem

[desgraci]

getting a null error when i try this:


            model1 = Collada.parse(Charmesh, {scaling:1,
material:manaC});
            model1.mouseEnabled=false;

            mesha = model1.getChildByName("model") as Mesh;
            mesha.rotationY+=180;
            mesha.rotationZ+=180;
            mesha.ownCanvas=true;
            mesha.pushfront=true;
            mesha.name="Mesh Alpha";
                var rx:Number= new Number(Math.round(Math.random() * (10000))
-5000);
                var ry:Number= new Number(Math.round(Math.random() * (10000))
-5000);
                var rz:Number= new Number(Math.round(Math.random() * (10000))
-5000);
                        mesha.x=rx;
                        mesha.y=ry;
                        mesha.z=rz;
            scene.addChild(mesha);

           meshc = model1.getChildByName("lpmodel") as Mesh;
            meshc.rotationY+=180;
            meshc.rotationZ+=180;
            meshc.ownCanvas=true;
            meshc.pushfront=true;
            meshc.name="Mesh Charlie";
            scene.addChild(meshc);

if i only add mesha works, if i add meshc, sucks

why? btw im using global vars
