Try changing this to:
- (void) dealloc {
self.object = nil;
[super dealloc];
}
'keyPathsForValuesAffectingName' is going to cause your wrapper to
observe its MyObject (not the observation that you set up manually,
but a different one set up internally). When the wrapper deallocs,
there's apparently nothing to cause this internal observation to be
removed, so the MyObject continues to be observed by a deallocated
object. At least, that's my theory.
Note that if each wrapper had its own object (so the MyObject is a
"attribute" of the wrapper), then [_object release] would actually
dealloc the MyObject, which (if I've got things the right way round)
would cause the unwanted observation to be removed automatically.
But you actually have a 1-1 relationship between the wrapper and the
MyObject, so you kind of need to break the relationship before
releasing the wrapper end of it.
