Hi, Vlad.
Thanks a lot for your explanation. Are you a MVP already? If you don't, you'll be very soon. :-)
Well, I'd like to eliminate this extra trip do the server to generate this newID, but I still didn't figured out how.
I'll keep studying, and if I discover something, I'll tell you, and everybody who is sending me their comments.
Thanks!
