Geoserver-users - NullPointerException with WFS GML request.

Hello,
When I submit a WFS request for GML, I recieve a NullPointerException, with
no error message in the response, but it looks like a GML2OutputFormat bug
in the log. I only get this error for GML format, not for KML or GeoJSON.
Please advise,
David

Hmmm... it will take more than just this report to figure it out.
For example, this request works just fine:
http://demo.opengeo.org/geoserver/wfs?request=GetFeature&service=wfs&version=10.0&typeName=topp:states&featureid=states.1
What's different in your setup?
