What is the state of a "rollbacked" managed object?

Hi list,

I have a bug in my application and don't really know how to solve it:

Suppose my program follows the steps:

1/ save the moc
2/ insert a managed object
3/ the user can edit the managed object (attributes mostly)
4/ the user can validate or cancel via a button.
5/ when validating via OK button, the MOC is saved. When cancelling via Cancel button, the MOC is sent a rollback message.


I *thought* that after the rollback, the managed object would be deleted (at least would return YES to isDeleted message). Unfortunately it is not the case: the managed object still exists, is in "no state" (not inserted, nor deleted) and all its attributes/ relationship are nullified.
Rollback is supposed to return the MOC to its previous state. I noticed that the managed object is "detached", it has no MOC.


can someone describe me what really happens to this managed object ? is it supposed to be deleted ? detached from the MOC (then freed ? when ?)

Thanks for any help.





Aurélien,
