google maps api v3 + infoBubble in markerClusterer

Question

I was trying to add an infoBubble to a markerCluster in the \'clusterclick\' event but the infoBubble.Open method ask for a \'marker\' parameter to bind with. The problem is

Answer 1

Solution problem 1: The marker parameter was optional If I just simply never assign it, the problem is solved.

Use:

infoBubble.setPossition(latLng);
infoBubble.open(map);

Not:

infoBubble.open(map, marker);

Problem 2: But now the infoBubble appears over the market, is there a way to move it up??

Solution problem 2:

I modified the InfoBubble sourceCode to contain a offsetParameter and then add the pixels in the draw function:

InfoBubble.prototype.PIXEL_OFFSET = 0
...
var top = pos.y - (height + arrowSize); if (anchorHeight) { top -= anchorHeight; } top -= this.PIXEL_OFFSET

Just in case someone had the same problem
