You probably mean "object._p_deactivate()".

This will not work when "object" was modified before.

Usually, "object" will not have an "url" method (or attribute).
Apart from that, this is a very good idea.

An alternative could be the use of a wrapper:

   from ExtensionClass import Base

   class _Wrapper(Base):
     def __init__(cat, obj):
       self.default_catalog = cat
       self.__obj = obj

     def indexObject(self):
       self.__obj.indexObject.im_func(self)
     ... similar for the other indexing related method ...

     def __getattr__(self, key): return getattr(self.__obj, key)
