class min_all(SimpleItem.SimpleItem,ObjectManager):

...

manage_options=(ObjectManager.manage_options +
({'label':'Edit Minimal', 'action':'manage_editMin_allForm'},
))

......

def addFoo(self,id,dn):

        "add Foo object to min_all object"
        O=Foo(id,dn)
        self._setObject(id, O)
        self._p_changed=1

def delFoo(self,id):

        "del Foo object from min_all object"
        O=Foo(id,dn)
        self._delObject(id)
        self._p_changed=1

Function delFoo and addFoo working normally. For example, I can't add second Foo object with existing id, and I can't del Foo object with not existing id.

But I can't see objects on ObjectManager.manage_options tab! I see only message: "There are currently no items in min_all1".

I think, that problem is in _getOb function of ObjectManager class.... How can I change this function?

And where can I read information about using ObjectManager class?
