So I expect there is a standard way to suppress an NSError... but in case I'm doing something too unusual, I'll add some background...

I have an interesting inter-property validation situation where I would like to deny a certain change to an object and instead handle it in my controller by creating a new object. (Sounds weird, I know, but it does actually make sense in context, I promise!). Since validate<Key>:error: is in the model, I thought it would make sense to deny the change and then use the NSError to pass the message to the controller layer. My NSDocument subclass can then catch the error, suppress it, and react appropriately.

But how exactly should I suppress the error?

Thanks,
George
