[mapguide-users] Problem with coordinate system

Could you enter a ticket for the coordinate select problem in Maestro:
(You must login with an OSGeo ID, and select Maestro as the component)

IIRC the layer's coordinate system must be the same as the map's 
coordinate system.
That means that a given point, say (5,3), must be at the same location 
in both the map coordinate system
as well as the layer data. If that holds, you simply have to read out 
what coordinate system your MapDefinition uses,
and use the same for the coordinate system override.

If they are not value compatible, I don't think it will work with the 
regular buffer procedures.
