Imran,
Thanks for the input. I have added a GetFeature control and a highlight layer based on http://openlayers.org/dev/examples/getfeature-wfs.html as follows: 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 selected features are not being added to the highlightLayer layer. According to Firebug, the numberOfFeatures="0". Do you have any idea why there are no features being returned? I use geoserver and WFS is enabled.

So, now I know I need to add another control. I appreciate your help. Jerome From: Gery .

I have tried unsuccessfully to also highlight the features selected in that same control by adding them to a highlight layer. Do I need a separate control using GetFeature in order to highlight the selected features? Any help would be greatly appreciated.
