ClusterMarkerer - no cluster appear - this.map_.mapTypes[this.map_.getMapTypeId()] is undefined markerclusterer.js:304

Question

I have an issue with my MarkerClusterer.

When i was 400 markers, cluster appears, all worked. But now i have moire than 600 markers and cluster don't appear.

Firebug display this error:

that.map_.mapTypes[that.map_.getMapTypeId()] is undefined  markerclusterer.js:304

Have you an idea?

Thanks
