[Zope-dev] how can I prevent undo?

[robert]

Thanks again,

I now added

    def undoable_transactions(self, first_transaction=None,
                              last_transaction=None,
                              PrincipiaUndoBatchSize=None):

        return ()

to my class. This seems to work. 
Is this advisable or are there caveat to be avare of?
Robert
