Have a look at the geoserver logs; it should be making a couple of requests;
getCapabilities; describeFeatureType
And then for each request it often uses getFeatures and describeFeatureType
(for the schema). You may have run into a geoserver configuration issue; as as
part of the getFeatures response ( a gml document) it refers to the schema
(which is a call to describeFeatureType from the same server). Please check
your getFeatures result using the geoserver demo requests just to be sure it
works correctly and refers to the schema correctly.
And yes please update the wiki example.
