setMap to null on polygon gives an zoom error

[kafura]

If I sets the map on a polygon to null, then it gives me an error when i'm zooming.

var polygon = new GoogleMapsPolygonLayer(<google map>);
polygon.setMap(null);

The error is:

Uncaught TypeError: Cannot read property 'getDiv' of null

I am trying to hide the polygon, is it the wrong way i'm doing it?

Consoder using polygon.div_.style.visibility = 'hidden';

GoogleMapsPolygonLayer extends google.maps.OverlayView() for further information on how to hide such an overlay please refer to https://developers.google.com/maps/documentation/javascript/examples/overlay-hideshow?hl=de
