[OpenLayers-Users] Filter not working

[Siva kumar Devineni]

Thank you very much Phil. I got it. I am sharing the code for all my
friends. this code first checks if the layer is empty and then proceed. the
clearData() is to do with destroying.

if(wfs_layer) {
map.removeLayer(wfs_layer);
clearData(wfs_layer);
}

var radiusPoint = new OpenLayers.Geometry.Point([longitude, latitiude]);
 var propertyFilter = new OpenLayers.Filter.Spatial({
        type:OpenLayers.Filter.Spatial.BBOX,
        property:'the_geom',
        value:new OpenLayers.Bounds(extreme_x,extreme_y,minimum_x,minimum_y)
    });
wfs_layer = new OpenLayers.Layer.Vector("settlements", {
strategies: [new OpenLayers.Strategy.BBOX()],
filter: propertyFilter,
protocol: new OpenLayers.Protocol.WFS({
version: "1.1.0",
url: "http://192.168.1.19:8081/geoserver/wfs",
featureType: "settlements",
featureNS: "www.gospatial.com",
srsName: "EPSG:900913",
visibility: true,
}),

})

map.addLayers([wfs_layer]);
