[OpenLayers-Users] Issues with some popups

[Nicholas Efremov-Kendall]

Hi all,
I'm having some issues with my code, and I'm not sure where the problem
lies. This code worked at one point, and I've been staring at it for too
long to see the problem. Two firebug errors fire when I click on one of the
POI's "feature.geometry is undefined" and "popup is undefined". Any
suggestions?


var map, layer, selectedFeature, selectControl, selectedFeature, sites;
function onPopupClose(evt) {
            selectControl.unselect(selectedFeature);
        }

function onFeatureSelect(feature) {
            selectedFeature = feature;
            popup = new OpenLayers.Popup.FramedCloud("chicken",

feature.geometry.getBounds().getCenterLonLat(),
                                     null,
                                     "<div style='font-size:.8em'>Site_ID: "
+ feature.attributes.title +"<hr />Locality: " +
feature.attributes.title+"<br/>Description: " +feature.attributes+"<br/>
Feature ID: "+feature.id+"<br/>Feature Type:"+feature.attributes.NEWSITE_
+"</div>",
                                     null, true, onPopupClose);
            feature.popup = popup;
            map.addPopup(popup);
        }
  function onFeatureUnselect(feature) {
            map.removePopup(feature.popup);
            feature.popup.destroy();
            feature.popup = null;
        }

function init() {
map = new OpenLayers.Map ("map",
{
controls:[
new OpenLayers.Control.Navigation(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.LayerSwitcher(),
new OpenLayers.Control.Attribution()],
sphericalMercator: true,
maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),
maxResolution: 156543.0399,
numZoomLevels: 19,
units: 'm',
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
}
);
 var sites = new OpenLayers.Layer.GML (
"Archaeological Sites", "data/siteswatr.gml",
{
style: {pointRadius: 2.5},
projection: new OpenLayers.Projection("EPSG:4326"),
format: OpenLayers.Format.GML
}
);
map.addLayer(sites);

sites.events.on({
'featureselected': onFeatureSelect,
     'featureunselected': onFeatureUnselect
});

            selectControl = new OpenLayers.Control.SelectFeature(sites,
                {clickout: true,
toggle: false,
hover: false,
}
            );
            map.addControl(selectControl);

            selectControl.activate();
if( ! map.getCenter() ){
sites.events.register('loadend', sites,
function(){map.zoomToExtent(sites.getDataExtent())});
map.setCenter(null, null);
};
}
