Isn't it good from the user's point of view for the new DO she created
to be where she put it? To me this is a good thing regardless of what
happens when the user or another user does a re-query. Having the extra
int argument isn't necessarily making all kinds of relational database
ordering promises.

It is a bit more involved than that. The problem with including this
in Cayenne is that it won't work in a more general case. E.g. if you
add an object at a particular index, and the master object is later
invalidated and refetched, the order will be lost. Or if it is
refetched by another user. So Scott's answer was essentially correct.
We tried to solve it from another angle, by defining a certain column
as the "ordering" column to instruct Cayenne to order fetched
relationship lists. It is still on the table, but it is also hairy...
For now I can't think of a clean generic solution that would map to a
DB. The ordering column is the closest I can think of.
Thanks,
