Hi All,
Updating an old application and have come across a very weird
situation. Code which was working fine 2 days ago now produces an
error. So I made the simplest test case I could and yet I still get
the error.....
GeneralInfo gi = (GeneralInfo)
EOUtilities.objectWithFetchSpecificationAndBindings(ec,
"GeneralInfo", "find", new NSDictionary());
gi.setUpdaterRunning(new Integer(3));
ec.saveChanges();
which produces the following SQL and error message
....

I don't understand why it wants to fetch the GeneralInfo object from
the database again? And I don't think I have ever seen SQL "FOR
UPDATE" which is tacked onto the end of the second select statement.
Can anyone suggest what may be going on and why ?
