WFS GetFeature produces Not valid GML

[John Ho]

 Hello,

I Just noticed that Mapserver 4.6.2 is giving me invalid GML for a polygon with one inner ring. 

Here is a snippet of the GML code:

<myns:msGeometry>
<gml:MultiPolygon srsName="epsg:4283">
        </gml:MultiPolygon>
</myns:msGeometry>

The error is an empty MultiPolygon.  There are no other errors produced by MapServer.  I have also noticed that GML that is produced, only Filled Polygon (no inner rings) are declared under the Polygon element, while a Polygon with inner rings are declared as a Polygon under MultiPolygon.  Anyone has any explaination for this?  This does not conform to the OGC GML standard.

I have also tried using ogr2ogr tool on the shapefile, and converted it to a GML.  Upon inspection, the GML conforms to the OGC GML standard and the missing feature is declared correctly.  I tried changing my map file to use a OGR connection to the GML file and I still get the same GML by Mapserver.  Is this a known bug of Mapserver?

I have also tried the same shapefile on GeoServer and GEOServer produced valid GML for the feature.

If anyone can tell me why I can't get the GML to produce correctly please let me know.  It would be a GREAT help if you are able help.  Email me if you would like me to send the shape file and mapfile.

Regards,
John
