NSManagedObjected isInserted
Can anybody ever think of a scenario where [NSManagedObject isInserted] equals NO for an object that is initially fetched from the context? And no the object has not been deleted from the context prior to calling isInserted. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The object should return YES for "isInserted" from the time it's inserted to the time the store is committed/saved. It's not clear where in this timeline your "initially" is pointing. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Later I call [NSManagedObjectContext insertObject:] and pass in the same NSManagedObject that was initialized earlier. On a subsequent run of my application I fetch the object from the store and call [NSManagedObject isInserted]. Without fail it always returns NO. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Without fail it always returns NO. If you read Quincey's post, he answers your question … after the store has been saved, its new objects return NO to -isInserted. The documentation for -isInserted makes no mention of this. But it wouldn't be the first time that Quincey was better than documentation. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Think of it as being equivalent to:
- (BOOL)isInserted;
{
return [[[self managedObjectContext] insertedObjects] containsObject:self];
}
Thus, objects only return YES when inserted into a context and not yet
persisted.___

Oh! Thank you for clarifying that, Mike. I just sent Apple some Document
