Hey,
Ondra's suggestion is the a good idea. Or you could have a look at
Chapter 9 of Chucks "Practical WebObjects" book, which is a whole
chapter on this very topic :)
And it requires an entire chapter because when you think about it, it
is NOT an insignificant thing to do:
- You may not want to clone all attributes for all entities
- You may not want to clone all relationships for all entities
- If cloning an object graph you may/will encounter circular
references that need to be dealt with.

Well what I mean is that instead of
neweo.setValue(existingeo.someValue());
for every value in the existingeo which I want to transpose to the
neweo.
Is there a operation like -
neweo = existineo.clone();
So all the values in the new eo are the same as existingeo but
obvioulsy with a new PK..

Has anyone had experience copying an EO values fetched and in and

"Atomic" in what sense?
Myself, I've always combined valuesForKeys and
takeValuesFromDictionary, but YMMV :)
