I have been working with MarkerManager with a 300 points dataset, and I find that if I set the zoom level of the markers being pushed to the MarkerManager is : Unable to get value of the property '135531': object is null or undefined
Trying to diagnose the problem I pinpointed the problem to the prototype function: MarkerManager.prototype.getGridCellCreate_ = function (x, y, z)
When it goes to assign the grid item:
var grid = this.grid_[z];
it claims that grid is undefined, and the value of z is 135531.
Could some one advise and help to resolve the problem
