[mapguide-users] Oracle FDO and View

[GordonL]

Yes, it does work, but it does not allow me to select features in the map.  

For example, I have a materialize view called MVIEW_PARCELS, it has a
spatial index on the GEOMETRY column and index on the GIS_ID column.  It has
a row in the MDSYS.SDO_GEOM_METADATA_TABLE.  

I can see everything on the map in MapGuide, but I cannot select individual
parcels.
