[OpenLayers-Users] removeFeatures + Cluster Strategy

[Heidt, Christopher M.]

Ok, to help anybody who also comes across this issue, you seem to have to do the following:

clusterStrategy.deactivate();
featureLayer.destroyFeatures(featureLayer.features);
clusterStrategy.activate();

If you don't deactivate the cluster strategy before removing your features then,
for some reason, the cluster strategy will still think they are there and will
contienue to make new clusters everytime you change your zoom level.

Anybody know how to fix this so I don't have to toggle strategy activation?

It seems to have the same behavior whether I use removeFeature or destroyFeature.
The features vanish correctly until I change my zoom lvl, then they all reappear.
They even contienue to dynamically cluster themselves.

Hi,

Try _featureLayer.destroyFeatures(_featureLayer.features) instead.
