Hi list!
I just want to stress Core Data users, since i've discovered what I
think is a huge bug, that I reported to apple.
Basically, save an object graph to a SQL store, reload it from disk,
the object graph is not restored correctly, some relationships are
missing.
You can download a very simple project that demonstrate the bug at
http://developer.gumitech.com/CoreDataDramaticalBug.zip
A Readme is included that explains the details.
I'm quite surprised that nobody here has encountered this bug, but
honestly I can't trust Core Data anymore, and I fear a customer
complain about data loss.
Just an optimist note, the bug can't be reproduced on Mac OS X
10.5... But IMHO Apple must fix it on 10.4 too.
