[mapguide-users] Map or Layer Preview don't show the Geometry

[Alexander Fischer]

Hi,
The Oracle SRID or rather the EPSG-Code is 24878.

Now I saw, that the WKTEXT which is shown in webstudio is a little bit
different to the WKTEXT in the MDSYS.CS_SRS - Table.
Could this be the problem? But what can I do for this?

Kind regards,
Alexander Fischer
