Image view binding doesn't update on nil values

Subject: Image view binding doesn't update on nil values
From: Ben Lachman <email@hidden>

I have an image view and its value binding is bound to a transient property of a CD object (a cached thumbnail). However when a user removes an image from the image view I am sending the image view [imageView setImage:nil] (or any similar variant). When I do this the CD object never gets its setter method called as I would expect. The reverse is also true--if I set the CD object's property using [imageMO setValue:nil forKey:@"thumbnail] the value is correctly set in the object but the imageview is not updated. Any thoughts on why this doesn't happen automatically?

Thanks,
->Ben
