Hi Bryan,
The exception reminds me to a recent Bugzilla but I can't find it at the
moment.
Can you please file a new Bugzilla so that I can investigate that tomorrow?
Important: Please indicate which version of CDO you used exactly.
Probably I'll also need some more details about the context, i.e. what
exactly you did in which order.
A test case to reproduce the problem as subclass of AbstractCDOTest is
always the best way to help us find and fix a bug (it's really easy and
lots of examples exist).
Also a zipped console log (which, for example, contains the exact SQL
statement that caused an exception) might be helpful.
Cheers
/Eike

Eike,
Stephen and I are working on the same project, and based on your reply
to his problem with an SQLException when loading a cross-model
reference, it sounds like we need to try the latest build.
I think we will try the latest build and see if that works. We are
quickly running out of time, and must decide wether CDO will work for
us, or if we must develop our own solution. We greatly appreciate your
quick responses to our problems.
Bryan
