[OpenLayers-Users] Problem with polygon layer

Mon Jun 17 11:38:41 PDT 2013

I can not get a polygon layer to display in my map.  I know my projection is
correct.  I am able to see the feature collection in the Chrome developer
tools.  I am trying to display the features on a Bing background map.  I am
able to display other layers types (points and lines) but not polygons.

html content:

var polygon_layer = new OpenLayers.Layer.Vector("Polygon Test", {
    strategies: [new OpenLayers.Strategy.Fixed()],
    protocol: new OpenLayers.Protocol.HTTP({
        url: "zoning_3857.geojson",
        format: new OpenLayers.Format.GeoJSON()
    })
});

geojson content:
