[Zope-dev] ZClass Instances

[Edgardo Zulian]

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
