Gregg,
have you tried to use the "updateActionListener" for some master/detail stuff?
It works pretty good!

What I've discovered is that if in the constructor I do setCurrentUser(new
User()), then when the values are being repopulated on a validation errror,
there is an object to apply those values to.
I guess what is sort of confusing me is the fact that, realizing how request
scope works, everytime the form is submitted a new copy of said managed bean
is being created. Although I was under the impression that the request is
being forwarded unless the REDIRECT tag is used in the faces-config for the
bean declaration and that the managed bean would be forwared along with that
request. However, would it be a true statement to say that the properties
of the backing bean are persisted across the request, but that the actual
backing bean object is not?
Thanks.

dataTable with a list of users. When I click on one of the users in the

appropriatly. However, when I try and submit the form, I get a conversion
error on firstName. I *think* it's because when the form is being validated
the currentUser object has been lost out of scope and so that phase is
getting NULL back for the value of firstName. Is this accurate? If so, is
there anything I can do to make this process work aside from putting things
in session.
