I think I identified the problem...

Look at this example:
http://openlayers.org/dev/examples/wfs-states.html

It creates a WMS layer with the map of the world, and then a WFS layer
of the United States.

I found that if I comment the first part, the WFS layer never shows, and
openlayers never makes a request...


It is the same problem I have here!
But why?




var map;
OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";

function init() {
    map = new OpenLayers.Map("map");

/*
    var base = new OpenLayers.Layer.WMS("OpenLayers WMS",
        "http://tilecache.osgeo.org/wms-c/Basic.py";,
        {layers: "basic"}
    );
    map.addLayer(base);
*/

    var wfs = new OpenLayers.Layer.Vector("States", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://demo.opengeo.org/geoserver/wfs";,
            featureType: "states",
            featureNS: "http://www.openplans.org/topp";
        })
    });
    map.addLayer(wfs);

    map.zoomToExtent(new OpenLayers.Bounds(-140.4, 25.1, -44.4, 50.5));
}
