hello to averyone.
I'm trying to upgrade an existing 2.6.1 mapguide system installed
on a window server 2008 to a new mapguide server 3.1.2 on a window
2016 server operating system.
The graphical data, polygons lines an points is stored in
postgres-gis database and alphanumeric data is stored in mysql
After instalations and mgp loadin from old to new server i get an
"layerObj is null"
The error appears when i select an object on the map.
Another problem probably related is the my legend tab is empty.
