[OpenLayers-Users] BBOX strategy loading all features

[Rohan Parkes]

I had this problem, and fixed it by manually setting the layer maxExtent to
the same as the map maxExtent. I don’t know why this was necessary, as I
would have expected that value to bubble up from the map into the layer.

Subject: [OpenLayers-Users] BBOX strategy loading all features

 

Hi,

 

I´m obviously missing something basic here...my BBOX strategy is still
loading all the features.

 

var BBOXStrategy = new OpenLayers.Strategy.BBOX();

 

            

            var highlight_style = new OpenLayers.StyleMap({

        "default": new OpenLayers.Style(OpenLayers.Util.applyDefaults({

            title: "WEA",

            graphicName: "circle",

            fillColor: "#56E3FF",

            strokeColor: "#3A3F3B",

            strokeWidth: 0.5,

            fillOpacity: 1,

            pointRadius: 7

        }, OpenLayers.Feature.Vector.style["default"])),

        "select": new OpenLayers.Style(OpenLayers.Util.applyDefaults({

            title: "WEA",

            graphicName: "circle",

            fillColor: "#FF0000",

            strokeColor: "#3A3F3B",

            strokeWidth: 2,

            fillOpacity: 1,

            pointRadius: 9

        }, OpenLayers.Feature.Vector.style["select"]))

    });

            

    var layer_wea = new OpenLayers.Layer.Vector('Windkraftanlagen', {

                        strategies: [BBOXStrategy],

                        protocol: new OpenLayers.Protocol.WFS({

                 url: "http://maps.zgb.de/geoserver/wfs?",

              version: "1.1.0",

              featureType: "wea_wgs84",

              featureNS: "http://www.zgb.de/postgis",

              srsName: "EPSG:900913"

           }),

        styleMap: highlight_style,

        visibility: false

    });

    map.addLayer(layer_wea);

 

 

have I forgotten something?

 

 

yours,

 

Rob
