Tried that - I in-lined it on the list for brevity's sake. The problem
is definitely with manage_clone not wanting to be used on a thing
inside the transaction that creates that thing.

I've tried this workaround, but can't seem to make it work.  In the
ZClass add method, I create the new instance, then pass this instance
to another DTML method to do the cloning.

Could you shed some light on where the ZClass instantiation
transaction ends?  I used an HTML form to get to the DTML method that
would do the cloning, thinking that the submittal of a form would
create another request, thus ending the current transaction. 
Apparently I'm confused about the difference between doing this and
redirecting.

Could you post a code snippet or two of how you did it?

Thanks,
Erik
