[mapguide-users] Feature Joins

[Campbell, Keith A]

Thanks Kenneth.
 
I will want the users to be able to select objects from the layer and
read the joined feature values, so I do have a problem.

The short answer is yes. 
I have no problems displaying maps/porperties when using ODBC for
secondary sources.

But, I have written a bit with Ronnie Louie form Autodesk, about
selections on such featuresets.
Ronnie can select from such a Join using my data, but I can't.

So unless, you want to select objects from the layer and read joined
feature values using the API, you should be fine.

The error message I get is:

OSGeo.MapGuide.MgFdoException: An exception occurred in FDO component. 
no string resource for id <1019> -

	All, 

	Can an ODBC Feature Source be used in a Feature Join (as the
secondary feature)? 

	Thanks,
