Hi,

I confirm that using a MgFeatureReader with a "geometry collection" (in my
case: polygon and polyline) throws an unclassified exception (I am using the
OSGeo SQL Server Provider spatial). The exception is thrown when the reader
find the first geometry collection and you cannot read the following
results...

It's kind of annoying because SQL Server transforms sometime (with the
MakeValid method) regular polygons into "geometry collection" (polygon +
line). So MapGuide doesn't render it to the map, and the MgFeatureReader
doesn't read it.
