Subject: [fdo-users] OGR provider in 3.4.0

I am trying to use the OGR provider in MGE2010 and it fails with an 
unclassified exception.

Digging a little with a custom build of the OGR provider, I can see that 
it creates the OgrConnection object
through the CreateConnection API call.

Then without calling any methods on the object, it disposes the object 
and returns the
unclassified exception.

The mapguide debug log shows this for "TestConnection":
Error: An unclassified exception occurred.
 StackTrace:
  - MgFeatureServiceHandler.ProcessOperation line 83 file 
d:\build\testarossa_nightly\build_30.1\ent\os\server\src\services\feature\FeatureServiceHandler.cpp
  - MgOpTestFeatureSourceConnection.Execute line 100 file 
d:\build\testarossa_nightly\build_30.1\ent\os\server\src\services\feature\OpTestFeatureSourceConnection.cpp    


And this for a preview:
Error: An unclassified exception occurred.
 StackTrace:
  - MgFeatureServiceHandler.ProcessOperation line 83 file 
d:\build\testarossa_nightly\build_30.1\ent\os\server\src\services\feature\FeatureServiceHandler.cpp
  - MgOpGetClasses.Execute line 105 file 
d:\build\testarossa_nightly\build_30.1\ent\os\server\src\services\feature\OpGetClasses.cpp
  - MgServerDescribeSchema.GetClasses line 1527 file 
d:\build\testarossa_nightly\build_30.1\ent\os\server\src\services\feature\ServerDescribeSchema.cpp    



Since the DescribeSchema call fails without ever calling DescribeSchema 
on the provider, I thought that the OGRProvider may be missing some 
required methods.
I suspect that Rfc23 might be the cause:
http://trac.osgeo.org/fdo/wiki/FDORfc23

This may be a MapGuide error, but I was hoping that someone from the FDO 
team had tested the OGR provider with an application that uses
the new schema functions, or could give a hint towards the problem.

Thanks in advance.
