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

[Alexander Fischer]

Hi,
I'm working with MapGuide Open Source (2.0.1), MapGuide Maestro and
King.Oracle (0.7.4).
The Dataconnection works and I created a map and a Layer where I attached a
Geometry with polylines.
Also I edited the Layer style and the initial map view but when I tried the
Preview the browser showed only the mapviewer with an empty map (no
geometry).

When I open the data with the webstudio there is an advice in the
Preview-window:
"The coordinate system is invalid.
Could not create coordinate system forward transformation with specified
coordinate systems.
Exception occurred in method MgCoordinateSystem.CCoordinateSystem at line
380 in file ..\CoordinateSystem\CoordSys.cpp"

My used Coordinate system is PSAD56 / UTM zone 18S (EPSG:24878)
So I checked the WKT Code with Web Tier Test:
PROJCS["PSAD56 / UTM zone
18S",GEOGCS["PSAD56",DATUM["Provisional_South_American_Datum_1956",SPHEROID["International
1924",6378388,297,AUTHORITY["EPSG","7022"]],AUTHORITY["EPSG","6248"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4248"]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",-75],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",10000000],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AUTHORITY["EPSG","24878"]]

Status: Pass

I don't know where the problem could be. Has somebody an idea?

I would be pleased to receive an answer.
Kind regards, Alexander Fischer
