[mapguide-users] Mapguide 2.0.2 and SQLite

[Kenneth Skovhede, GEOGRAF A/S]

Can you render the layer if you put it in a map?
The preview function tries to read the spatial context to determine the
display extents of the preview, but since that fails, it won't preview.

When you view the layer in a map, it won't try to read the spatial extents.
