Thanks to Derek's excellent example last week of using point clustering on a feature map, I've been able to implement this function into a map I'm developing. The only problem I can't figure out is how to dismiss an old point cluster and get a new one generated. I've looked at the ClusterLayer.js and saw a function called clear so I added that to my code ... clusterLayer.clear(). The cluster graphic gets removed but a new cluster graphic isn't generated. I just have a blank map with no clusters. I know I have values available for clustering because when I do a clusterLayer.length, I get a count of the records found. It just won't generate a new cluster graphic. Has anyone tried to dismiss an old cluster graphic and get a new one?
