[OpenLayers-Users] force update markers layer

[Bartłomiej Burkot]

Hello Jan,

I think you have the same problem as my. Just add "resFactor to the BBOX.Strategy".
http://dev.openlayers.org/docs/files/OpenLayers/Strategy/BBOX-js.html#OpenLayers.Strategy.BBOX.resFactor
Try using something like:

new OpenLayers.Layer.Vector("Punkte", {
	strategies: [new OpenLayers.Strategy.BBOX({resFactor:1})],
	protocol: new OpenLayers.Protocol.HTTP({
		url: "text_layer_generator/points.php",
		format: new OpenLayers.Format.Text({
			extractStyles:false
		})
	})
});

I hope it helps.

Bartek
