Function clearMarkers break everything

[GoogleCodeExporter]

When I call 
    markerCluster.clearMarkers();
    delete markerCluster;
        markerCluster = new MarkerClusterer(map, markers); 

After these actions master clusterer stops redrawing clusters. 

Could you, please, give me a right way to clear clusters, load new data and
show it (for google map v3).

I had the same problem as well. I fixed it by only declaring my MarkerClusterer 
once during initialization:

markerCluster = new MarkerClusterer(map);

and then adding markers using a loop after clearing. Something like:

markerCluster.clearMarkers();
if(markers)
{
  for(i in markers)
  {
    markerCluster.addMarker(markers[i]);
  }
}

Hope that helps steer you in the right direction. :D

I'm not able to replicate your problem. It maybe have been fixed with recent 
releases.

Hi... Just an observation. You do not need to do this 'for', simply just use 
the 'addMarkers':

if (markers) {
    markerCluster.addMarkers(markers);
}
