> JabberXMLReader(ProtoObject)>>doesNotUnderstand:

Nick,

one additional hint:
When you file in a class that requires a superclass that does
not exist in your image, the new class is made a subclass of
ProtoObject. This is a source of difficult to find errors.
Please check out:
1. What is the required superclass of JabberXMLReader?
2. Does your image that required superclass? If not,
    where is a change set that can be used to install it?

Hope this helps more than my first response to your
mail

Greetings, Boris
