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'
         }
 }}
