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
