[mapguide-users] Parent groups missing from RuntimeMap

[Hans Milling]

Using MapGuide OS 2.2 and Maestro API 4.0.4, I have a problem when creating a
runtime map.
The map has a group childcare and a sub group schools with some layers
(public, private etc). When I use the CreateRuntimeMap all the groups are
created with no parent groups (the RuntimeMapLayer.Group is always an empty
string). When I look in the MapDefinition BaseMap the groups are there and
with their parent groups.

The source looks like this:
      IServerConnection con =
ConnectionProviderRegistry.CreateConnection("Maestro.Http", ...); 
      IMapDefinition mdef =
(IMapDefinition)con.ResourceService.GetResource("library://maps/testmap.MapDefinition");
      IMappingService mSvc =
(IMappingService)con.GetService((int)ServiceType.Mapping);
      RuntimeMap rtm = mSvc.CreateMap(mdef);

The rtm.Groups only contains the groups that has layers and none of them has
any parent groups.
If I preview the map from Maestro the legend is correct with nested groups.
Is there another way to load the runtime map getting the correct group
structure?

I looked at the Maestro source and the RuntimeMapGroup.cs constructors do
not save the parent group from the IMapLayerGroup property into the new
RintimeMapGroup. Is there a reason for this? Also why does it work in
preview in Maestro, is there another way to load the runtime map where the
groups are correct?

Best regards
  Hans Milling...
