mportant is to also enable your WMS Layers for WFS through the metadata object. See the examples DefaultOptionsWorld.js, for example the USA States Layer (only ‘fromWMSLayer’ value is currently supported):

new OpenLayers.Layer.WMS(
        "USA States (OpenGeo)",
        'http://suite.opengeo.org/geoserver/ows?',
        {layers: "states", transparent: true, format: 'image/png'},
        {singleTile: true, opacity: 0.9, isBaseLayer: false, visibility: false, noLegend: false,
                    featureInfoFormat: 'application/vnd.ogc.gml', transitionEffect: 'resize', metadata: {
            wfs: {
                protocol: 'fromWMSLayer',
                featurePrefix: 'usa',
                featureNS: 'http://usa.opengeo.org'
            }
        }}
