It's not importent for Foo class. I solve this problem. I change
"class min_all(SimpleItem.SimpleItem,ObjectManager):"  to "class
min_all(ObjectManager,SimpleItem.SimpleItem):". Now objects of min_all class
see ObjectManager.ObjectItems first!

Thanks :).
Exists (UML) Class Diagramm for Zope Classes, like ObjectManager, SimpleItem
_ etc? Where can I see this?
