But most often, I am eating my cake and still having it by creating the EO first, but saving it into EC only when properly set up. That way, it can be wired up directly, and still, if the user abandons it, it just vanishes when the GC decides so :)
Doesn't this violate one of the ten commandments of EOF? Isn't one of them that you're not supposed to update an EO prior to inserting it? I've not been able to find good docs as to WHEN that actually causes problems though (one of our internal apps does this, too, and it seems to work fine, but I gather it will burn us under certain circumstances).

Far as I can say from a pretty long experience, there is no problem, presumed you are pretty careful not to mix in relationships objects which are in EC with those which are not. Never been bitten in my bottom with this.


Matter of fact, a few times when needed I've even dared to create relationships from non-EC objects to EC-ones (the inverse relationships, of course, were set up only just before saving when inserting the new EOs into EC), and even it did work well without problems. That though I do not recommend for important public applications :)

Of course, you have to be wary with whatever code might presume there is an EC, like with using undo manager or so.
