[mapguide-users] Problem with MgSelection's GetSelectedFeatures

[Jackie Ng]

Have you tried using the MgMap(MgSiteConnection) constructor? I get a feeling
the selection you've created assumes the map was created with this
constructor.

Note that if you do change constructors, you should be calling the overloads
of Open(), Create() and Save() without the service parameters.
