Then for your project replace ProtoObject by�StubRootClass in�UndefinedObject>>subclass:instanceVariableNames:classVariableNames:poolDictionaries:category: it will work.

An alternative is to catch�OCSemanticWarning or its subclass OCUndeclaredVariableWarning while loading the new classes and execute another code instead of the default action in the exception handling block

I will check and see if I can set up a hook because having classes subclasses of protoobject is not a good idea
when loading broken code.

No because I have no idea what are the classes whose superclasses are not in the image.
With a proper hook I could just say
� � � � if the superclass is unknow please use the "StubRootClass" of my framework.
� � � � else let the system handles it.
