Hi -
I'm wondering if anyone has coded up a means to create an extension for a %Persistent class from a base class to a sub-class without making a ton of assumptions about the Global structure. I'm trying to create a new "extension" record that would have the same ID as the Base Class
Class BaseRecord Extends %Persistent
and
Class SubRecord Extends BaseRecord
where I would have an instance of a "BaseRecord" and I want to turn it into a "SubRecord" instance and have all of the existing references to the BaseRecord survive.
