An administrator builds a freeform Visual Task Board with three lanes named Waiting, In progress and Done, then creates a card on it for each piece of work the team has agreed to do this week. A team member drags a card from Waiting to In progress and afterwards reports that the State field of the matching incident is unchanged. What explains the behaviour?
- AThe drag succeeded but a business rule on the incident table reset the State value afterwards
- BThe lanes were created before the cards, so the board holds no mapping between them yet
- CThe team member lacks the role that a write access control rule on the State field requires
- DFreeform lanes are not bound to a field, so the card position is held only by the board Correct
Why A is wrong: Tempting because a server rule can indeed overwrite a value after an update, but no update to any incident was submitted here, so there was nothing for a rule to react to.
Why B is wrong: Sounds like a sequencing problem an administrator could cause, but the order in which lanes and cards are made has no bearing on whether a board type binds lanes to a field.
Why C is wrong: Plausible because access control does govern who may change State, but a denial would be reported to the user rather than leaving a silent move, and no field write was attempted.
Why D is correct: Correct because a freeform board keeps its own lanes and cards, with no data source and no field mapping, so moving a card records progress on the board alone.
