[OpenLayers-Users] Highlight on hover

[Steve.Toutant at inspq.qc.ca]

Hello,
With the code below, a GetFeatureInfo request is succesfully launched to 
mapserver when I stop moving the mouse. In firebug I see the XML response 
with the msGMLOutput tag. 
I can see that the highlightLayer has feature added to it but I don't see 
them on the map. Like there is no geometry.
What could be the reasons for that please? Is there some params missing?

Thanks
Steve

var highlight_style = { fillColor:'#99CCFF', strokeColor:'#3399FF', 
fillOpacity:0.7 };
highlightLayer = new OpenLayers.Layer.Vector("HighlightedFeatures", 
{displayInLayerSwitcher: false, features:[], isBaseLayer: false, 
visibility:true, style:highlight_style}); 

infoControls = 
{
                hover: new OpenLayers.Control.WMSGetFeatureInfo
                ({
                title: 'Identify features by clicking',
                layers: [overlays['national_2006']],
                hover: true,
                queryVisible: true
                ,infoFormat:'application/vnd.ogc.gml'
                })
}
// add layers to the map
addLayersToMap();

for (var i in infoControls) 
{
        infoControls[i].events.register("getfeatureinfo", this, showInfo);
        map.addControl(infoControls[i]);
        infoControls[i].activate();
}

function showInfo(evt) 
{
        if (evt.features && evt.features.length) 
        {
                 highlightLayer.destroyFeatures();
                 highlightLayer.addFeatures(evt.features);
                 highlightLayer.redraw();
        }
}
