[odb-users] Problem with updating a transient object when adding
a ptr in a to-many relationship

I found the problem while writing a test case for you.
My database was set up with the intermediary table having IDENTITY on the
Index INT IDENTITY
It was stipulated as such in the #pragma for the fields to accommodate for
the database attributes. But it caused the "object_already_persisted"
exception. When I removed the IDENTITY setting on the Index column,
everything worked fine. I also see that ODB handles the INDEX column the
same as an IDENTITY column, and it is not needed to have it on the table.

That would mean the object that 'John' points to is not persistent, for some
reason. Try to print the object id of object(s) that are in John's vector
and see if they are actually in the database.
If that doesn't shed any light, then I will need a small but complete test
case that I can use to reproduce the problem.
