The only way would be to implement the serialization yourself, i.e. 
implement `toData` and `fromData`, but I don't think there's a way to 
check if a field is present in the serialized data. So it might not be 
so easy.

You can set the "errorCallback" [1] to an empty delegate or whatever you 
see fit. But this callback will be called for other errors as well.
