Re: (Leopard) Core Data validateForDelete problem



I see that it will not be possible so save a context with a reference to a deleted object. But I selected the default "Nullify" rule. So no references should be there when deleting an object.
Should this not be recognized by the validation system when I call validateForDelete:?


When performing directly deleteObject: it will work. (But if I override validateForDelete to perform own validation and call super in there => validation error from the super method call).

So my question: How to validate for deny rules/nullify rules before deleting an object?

I'm not able to delete relationships when delete rule is "Nullify". Performing "validateForDelete" fails for each relationship. It comes up with a validation error under Leopard. Under Tiger it works as aspected.
