The ideal situation to me is something like data validation on server, errors / exceptions being risen and then catched by the client code that will translate them to a suitable message. Inserting data validation on client side helps with simple input and eliminate the average number of roundtrips needed for getting the data stored, but shouldn't be the only validation done. -- Jorge Godoy <jgodoy@xxxxxxxxx>
