[OpenLayers-Users] Cluster strategy not working

[Jerome Freyre]

Hi Max, 

Personnally, when I use Cluster Strategy, I create separatly the strategy
and the I activate it.

		
			var strat = new OpenLayers.Strategy.Cluster({distance:20});
			vectorLayer = new OpenLayers.Layer.Vector("Vektorlayer",{
			strategies: [
				strategy
			],
			styleMap: vectorStyle2, maxResolution: 19});
			strat.activate();


Hope it will be usefull....

Sincerly,
Jérome
