Hello Asle,I don't know if this could solve your problem, but I am using a vector layer as well.
Defining the WFS protocol looks a bit different from yours:
wfs = new OpenLayers.Layer.Vector(
"Name of the Layer",
{
strategies: [new OpenLayers.Strategy.BBOX()],
projection: new OpenLayers.Projection("EPSG:4326"),
protocol: new OpenLayers.Protocol.WFS({
srsName: "EPSG:4326",
url: "http://localhost:8080/geoserver/wfs";,
featureType: "rohre_graben_damm",
featureNS: "http://www.openplans.org/topp";,
})
}
);
I hope this can help you.
Regards,
Ingo
