I am using GeoServer and OpenLayers, and new to both. I am trying to
highlight features using an OpenLayers control on a WMS layer from
GeoServer. According to the response to the GetFeature request in Firebug,
the numberOfFeatures="0". Can someone make a suggestion as to what the
problem may be? The code is below:
var highlightLayer = new OpenLayers.Layer.Vector("Highlighted Features", {
styleMap: myStyles,
displayInLayerSwitcher:
false,
isBaseLayer: false
}
);
var highlightControl = new OpenLayers.Control.GetFeature({
protocol:
OpenLayers.Protocol.WFS.fromWMSLayer(mylayer),
box: false,
hover: false,
maxFeatures: 20
});
highlightControl.events.register("featureselected", this,
function(e) {
highlightLayer.addFeatures([e.feature]);
});
highlightControl.events.register("featureunselected", this,
function(e) {
highlightLayer.removeFeatures([e.feature]);
});
map.addControl(highlightControl);
highlightControl.activate();
The portion of the GeoServer log from the request is below:
2013-03-04 13:49:09,373 INFO [geoserver.wfs] -

Any help you may provide is greatly appreciated.
Thanks.
