This is usually a bounds or projection issue.
Make sure your map and datasource have the correct (preferably same)
coordinate system.
Also make sure that the extent on the map is et correctly.
The layer preview is known to be a bit shaky, because the data extents
are reported
incorrectly by some FeatureProviders.
Also, be sure to check the MapGuide error log for messages.

Hi List
I have instelled MGOS 2.0.2, postgresql 8.3 and posgis 1.3.6 and FDO
postgis 3.3.
I had gps points in access, and imported that into a postgis table. I
then executed the following lines to generate the geometry column.
SELECT AddGeometryColumn( 'public', ‘ruwis2’, 'the_geom', 4326,
'POINT', 2 );
UPDATE waterpoints2 SET the_geom = PointFromText('POINT(' || gps_e ||
' ' || gps_s || ')',4326);
I can connect to the database using maestro and have added the points
layer. When viewing the postgis data in QGis, it apreas fine.
Now, when trying to display this layer information in either the layer
preview, or in a map, nothing is displaying. Any ideas?
Andre
