Hello,
thanks for your post. I tried this but it doesn't work. Here is my code.


var control = new OpenLayers.Control.GetFeature({
protocol: OpenLayers.Protocol.WFS({
            readFormat: new OpenLayers.Format.GeoJSON(),
            formatOptions: {
                outputFormat: "JSON"
            },
            url: "http://localhost:8080/geoserver/wfs",
            featureType: "MY_LAYER",
            featurePrefix: 'topp',
            featureNS: "http://www.openplans.org/topp",
            geometryName: 'GEOM',
            maxFeatures: 100,
           defaultFilter: my_filter
   })
   });
   
control.events.register("featureselected", this, function(e) {
    select.addFeatures([e.feature]);
});

map.addControl(control);
control.activate();

When I launch my app I get an error that feature.lenght is null or doesn't
exist?

Do I have to implement a map.events.register as I did it with my
getfeatureinfo or is there something else wrong.

Thanks for your help

Regards
