I am trying to add a WFS Layer with a BBOX strategy. When I change the extent I want GeoServer to return only the features in that extent. Here is the code I am using to add layer.
wfs = new OpenLayers.Layer.Vector("Fields_WFS", {
strategies : [new OpenLayers.Strategy.BBOX()],
protocol : new OpenLayers.Protocol.WFS({
version : "1.1.0",
url : GEOSERVER_HOST + ":" + GEOSERVER_PORT + "/geoserver/wfs",
featurePrefix : "rpid",
featureType : "FIELDS_SUBSET_BNG_OSGB36_1",
featureNS : "<URI>",
srsName : "EPSG:27700" //default
}),
});
The map is set to a maxextent initially. And I have restricted WFS features to max 100 in geoserver settings.
My problem here is it only shows the same features every time I load and when I move or zoom +- it does not refresh WFS features.
Thanks,
JP

Try this in the layer definition:
works for me.
Also note that by default the BBOX strategy requires that you zoom/pan quite a lot before a new request is issued. Try changing the ratio and resFactor params to lower the threshold.
The explanation for their meaning is in the code.
