Hi, I am implementing a kind of Copy function which will strip off the sub level of object being copied. The idea is to copy only the object marked for copying - without the sub objects. (For those interested: I use these objects as special kind of reference objects in my structure.......) In the new copy routine I have added these lines which avoids having the sub level created: [ ....] newObject = ob._getCopy(self) for zob in newObject._objects: delattr(newObject, zob['id']) newObject._objects = () [ ..... ] self._setObject(newObject.id,newObject) # add the object to the Zope database ... delattr is the same method as used by _delOb, so I assumed this is the safe way of doing it. Can anyone tell me if this is not OK ? It seems to work very well .... Best regards Petter Enholm Snapper as www.snapper.no
