I am adding the layer like this:

		var wfs_layer3 = new OpenLayers.Layer.Vector("WFS Layer 3", {
			strategies: [ new OpenLayers.Strategy.BBOX(), saveStrategy],
			protocol: new OpenLayers.Protocol.WFS({
				url:  "/geoserver/wfs",
				featureType: "user_layer.layer_name",
				featureNS: "http://geoserver.sf.net",
				featurePrefix: "sde",
				srsName: "EPSG:900913",
				version: "1.1.0",
				geometryName:"SHAPE"
			})
		});
                 map.addLayers([wfs_layer3]);
