[OpenLayers-Users] featureadded

[Puneet Kishor]

The following code is supposed to create a Google Maps base layer, and a point using an external graphic that is rotated (az) and has height (rate) described by the attributes passed when creating the point. A "featureadded" event is supposed to create a popup anchored at the point showing "az" and "rate". The code doesn't work. The base layer is created but neither the point nor the popup are created. Suggestions?

    var proj = {
        "google": new OpenLayers.Projection("EPSG:900913"),
        "latlng": new OpenLayers.Projection("EPSG:4326")
    };
    map = new OpenLayers.Map('map', {
        "maxExtent": new OpenLayers.Bounds(-20037508, -20037508, 20037508, 20037508),
        "maxResolution": 156543.0339,
        "proj": proj,
        "units": "meters"
    });
    map.addLayer(new OpenLayers.Layer.Google("Google Physical", {type: google.maps.MapTypeId.TERRAIN}));

    map.setCenter(new OpenLayers.LonLat(-89, 43).transform(proj.latlng, proj.google), 2);

    var styleMap = new OpenLayers.StyleMap({
        "default": {
            externalGraphic: "arrow.png",
            rotation: "${az}",
            graphicWidth:6,
            graphicHeight: "${rate}"
        }
    });

    var vectorLayer = new OpenLayers.Layer.Vector("Simple Geometry", {styleMap: styleMap});
    
    // create a point feature
    var points = [];
    var p = new OpenLayers.Feature.Vector(
        new OpenLayers.Geometry.Point(-72, 42).transform(proj.latlng, proj.google), 
        {attributes: {az: 76, rate: 33}},
        {styleMap: styleMap}
    );
    points.push(p);
    
    vectorLayer.addFeatures(points);
    
    vectorLayer.events.on({
        "featureadded": function(evt) {
            feature = evt.feature;
            var str = "";
            for (var i in feature.attributes) {
                str += "<b>" + i + ":</b> " + feature.attributes[i] + "<br />";
            }
            map.addPopup(new OpenLayers.Popup.FramedCloud(
                "featurePopup",
                feature.geometry.getBounds().getCenterLonLat(),
                new OpenLayers.Size(50, 30),
                str,
                null,
                true,
                null
            ));
        }
    });
    map.addLayer(vectorLayer);
