I think that makes sense.

Hi Walt,

The newSelection may be assigned from the MgFeatureInformation's selection, which doesn't have an attached MgMap instance. We need an attached MgMap for
MgSelection::GetLayers() to be able to return MgLayer instances from the internally encoded selection information.

We could refine the logic to only call SetMap() if it wasn't assigned via "new MgSelection(map)"

- Jackie
