Hi Chuck,
It was an NSArray with 71 elements, but it contained 71 instances of only one EO. If I clicked the link to bring up the edit screen, I would get that same one EO for all 71 links, so I'd say yes; they all had the same GID.
If I ran the SQL that the console showed was run to fetch the data for the NSArray, it would return what is expected; 71 rows, one each of the 71 rows in the table.

The value stored in the DB field was not too long for an INT and an ALTER TABLE statement changed it without issue. Apparently there something about the process in the JDBC driver or EOF that chokes on it turning a Long into an Integer, but not enough to throw an exception, but enough to make all the values the same, in a non-deterministic way. If I quit and relaunched the app, it would likely repeat a different instance, but not always.
