The ExtensionClass docu tells that among all classes involved
in a class, at most one extension class may define data extensions.
Apparently, ZCallable is such an extension class that defines
a data extension (or inherits from a class that does).
And obviously, your class derives from another such class.
If you are lucky, ZCallable is a superset of
the other class and you can drop the other.
Unfortunately, I do not know with ExtensionClass'es define
extensions.
