[OpenLayers-Users] OL 2.10 - Vector layer will not render

[Mark K. Zanfardino]

OpenLayers version 2.10
MapServer version 5.6.6

Goal: Render vector layer based on WFS protocol

I'm trying to understand why a vector layer will not render on my map. I 
can clearly see the layer in the layerSwitcher control so I presume the 
layer is being presented, but there are no actual features rendered.

The vector layer is defined using a WFS protocol:

    tens = new OpenLayers.Layer.Vector("TENS",
           {
           strategies: [new OpenLayers.Strategy.BBOX()],
           protocol: new OpenLayers.Protocol.WFS({
               url: mapPath,
               featureType: "tenszones",
           }),
           styleMap: new OpenLayers.StyleMap({
               strokeWidth: 3,
               strokeColor: "#333333"
           }),
           filter: new OpenLayers.Filter.Logical({
               type: OpenLayers.Filter.Logical.NOT,
               filters: [
               new OpenLayers.Filter.Comparison({
                   type: OpenLayers.Filter.Comparison.EQUAL_TO,
                   property: "name",
                   value: "County0"
               })
               ]
           })
           },
           {
           isBaseLayer: false,
           buffer: 0
           }
       );

When I watch the page load I can clearly see the XML results from the 
WFS call (see XML output) but no features are rendered on the map. I'm 
following from the 'WFS Protocol and Filter' example. Any help would be 
appreciated.
