I might see what you want to point out. E.g. the table is COLOURS. The rec with id 1 is RED, the one with id 2 is BLUE, 3 is GREE and so on. Now you load these values into the dropdown box that sports RED, BLUE, GREE and so on. While someone selects GREE, there is a maintenance release changing GREE to YELLOW. So when that someone sends the selection by id to the backend, not GREE is selected but YELLOW. A) Your release changed the sementics of the record 3. It's meaning changed. I cannot recommend doing that. B) If you absolutely must change the semantic, put your application into maintenance mode in which noone can select anything beforehand. If the maintenance would just correct the typo from GREE to GREEN, nothing would happen. Yor customer still ordered the lavishly green E-Bike her hear ever desired.
