[Users] wfs tree selector

[Christian Mayer]

Hi Jim,

I am not quite sure if I undestood you right, but maybe you use two
vector layers with a WFS protocol and a filter, for example like this:

new OpenLayers.Layer.Vector("WFS", {
                strategies: [new OpenLayers.Strategy.BBOX()],
                protocol: new OpenLayers.Protocol.WFS({
                    url:  "http://demo.opengeo.org/geoserver/wfs",
                    featureType: "tasmania_roads",
                    featureNS: "http://www.openplans.org/topp"
                }),
                styleMap: new OpenLayers.StyleMap({
                    strokeWidth: 3,
                    strokeColor: "#333333"
                }),
                filter: 
                   new OpenLayers.Filter.Comparison({
                       type: OpenLayers.Filter.Comparison.EQUAL_TO,
                         property: "TYPE",
                           value: "deed"
                    })
            })
