[Users] [OpenLayers-Users] Control not working when implementing FeatureInfo

[Smaran Harihar]

ya it is but I thought that when I am creating the new popup it should not
be a problem. The reason it is null is because I am making it null. Here is
the function for the popup,

if (!popup) {
    popup = new GeoExt.Popup({
        title: "Feature Info",
        width: 200,
        maximizable: true,
        collapsible: true,
        map: panel.map,
        location: loc,
        anchored: true,
        listeners: {
            close: function () {
                // closing a popup destroys it, but our reference is truthy
                popup = null;
            }
        }
    });
}

Thanks,
Smaran
