Be careful of how you interpret "if it seems complicated you are not
doing it right". While WO makes a lot of common programming tasks
trivial it does not make everything trivial. Some things are just
inherently complex. While it will make the application part of your
nuclear physics application easy, it won't make the nuclear physics
part easy. You'll have to wait a few centuries for that. :-)

I found the code posted by Gary Teter on the Omni webobjects-dev mailing
list. If anyone else is looking for this code you can find it by doing
a search on "deepCopy" it was posted Dec 11 2001 with the somewhat odd
subject of "Cloning an WO in Java". Fortunately for me from my testing
so far I think this code is going to work pretty much exactly as posted.
My EOModel is setup so that the payment request owns its payment items,
but not the user, or requesting department objects (which I would not
want to duplicate). The payment items own their account numbers, but do
not own the actual account objects, or expense code and vendor objects
(which I would not want to duplicate). This code works well for my
situation as I do not have any objects that are not owned by the parent
eo that I would want to duplicate. So in the end I did only need to
write a few lines of code to make this work. Thanks for the help all.

Taking (my interpretation of) Albert's example, we have a complex PO
that we want to use as a template for a new, very similar PO. We want
to copy the the PO and PO items as brand new objects.
This is exactly what I was trying to do.
