Have you tried using the __class__ attribute of the instance to compare the the two? Maybe do a propertyIds, and compare getattr(self,id) to getattr(self.__class__, id)? I'm just guessing though cause I haven't tested either of these methods. Tim

Yes, but i know that the object is an instance of a zclass,
what i want to know if the instance propertysheets's properties (lines, string, multiple lines) have de same values as the zclass have.
For example if i have a zclass 'x' with a string in the propertysheets wich a default value, when i create an instance of that zclass 'x1' it has that value on the property string, but if i change that value to another, then when i change de default value of the zclass, the value of the instance will not change. So how can i recognize when an instance do not take the changes that i make to the zclass?
Thanks Edgardo

How about just using meta_type? on the zclass this'll be 'Z Class' and on an instance of the ZClass, it'll be that meta_type.

Hi,
I have a zclass, which have a propertysheet with some
properties like
multiple lines, strings, etc.. which have some default values that i assigned to them. When i create an instance of that zclass and i change the value of a property, then the instance does not reflect any more the changes that i make to the zclass, which is okey.
So the question is: There is a way to know using an external method or with a dtml, if an instance is different from the zclass?
Thanks..
Edgardo
