[away3d] Frustum clipping error:1009

[GBear]

Hi Guys

My scene works fine until I apply Frustum clipping then i get
error1009 a mile long.

I have 2 .obj and 8 textfield3D in an ObjectContainer3D

Any help appreciated thanks in advance.

 function initEngine():void
{
        scene = new Scene3D();

        clipping = new FrustumClipping();
        clipping.minZ = 10;

        camera = new HoverCamera3D({zoom:2, focus:300, distance:1000});

        camera.panangle = 0;
    camera.tiltangle = 0;
        camera.targetpanangle = camera.panangle = 180;
    camera.targettiltangle = camera.tiltangle = 0;
    camera.mintiltangle = -90;


        view = new View3D({renderer:Renderer.INTERSECTING_OBJECTS});
        view.scene = scene;
        view.camera = camera;
        view.clipping = clipping;
}

some of the error list:
