Hi all,
I'm facing an issue with a simple app-schema mapping targeting the Geology Core 
INSPIRE schema, which can be found here:
file:///home/stefano/Lavoro/GeoSolutions/projects/hale/geoserver-2.6.2/data_dir/app-schema-cache/eu/europa/ec/inspire/schemas/ge-core/3.0/GeologyCore.xsd

I'm attaching a simplified version of the mapping file.

Example request:
http://localhost:8080/geoserver/ows?service=WFS&version=1.1.0&request=GetFeature&typeName=ge:MappedFeature&maxFeatures=50&outputFormat=application%2Fgml%2Bxml%3B+version%3D3.2

Stack trace of the error:
java.lang.RuntimeException: Failed to get properties. Binding for 
{http://www.opengis.net/gml}AbstractFeatureType

From the error message of the exception's root cause, marked in red, it looks 
like NaturalGeomorphologicFeatureType was not properly parsed and added to the 
schema index, not sure why. Also the message "Failed to get properties. Binding 
for {http://www.opengis.net/gml}AbstractFeatureType"; sounds wrong to me: 
shouldn't have been "{http://www.opengis.net/gml/3.2}AbstractFeatureType";, 
since the geology schema links to GML 3.2?
I tried to change output format to "gml3" and the exception disappears, 
although the output is not perfect (e.g. "shape" geometry element is not 
properly encoded):

        </ge:NaturalGeomorphologicFeature>
      </ge:specification>
    </ge:MappedFeature>
  </gml:featureMember>

I tested with GeoServer 2.7.1 and master, obtaining similar results.

Does anybody have an idea of what might be going wrong?

Best regards,
Stefano Costa
