[fdo-users] Resource ID does not refer to a valid feature source

[Heddo Klandermans]

I installed MG Enterprise 2011 (incl. MG Studio 2011) and found all 
working well again (after some initial trouble) using the FDO 3.5 
PostgreSQL-provider (comes within the MG Enterprise package).
Connection was made to PostGreSQL 8.4.5.1 /PostGIS 1.5.2.1
Nice to know: Also MG Studio 2010 could be used to connect to the MGE 
2011 environment (based on Apache).

In a next stage I will test the combination of MGE Studio 2011 and MG OS 
2.2 and also the connection to the latest PostgreSQL 9.0 and PostGIS 
1.5.2.3.

I know that there were a number of outstanding defects logged against the PostGIS provider that were never resolved. You might want to try the FDO 3.5 release and its PostgreSQL provider to see if using that provider resolves your issues. However, that would mean you would need to move to the version of MG that is compatible with FDO 3.5.
