Fixes #17111 ### Problem When creating a Relation field, after deselecting the pre-selected default object (e.g., Company) and selecting a different object (e.g., Opportunity), both objects would end up being selected, showing "2 Objects" instead of just the newly selected one. ### Root Cause The `initialMorphRelationsObjectMetadataIds` array was being recreated on every component render, causing react-hook-form's `Controller` to treat the `defaultValue` prop as a new value and re-apply it after user changes. ### Solution 1. **Memoized the initial value**: Used `useMemo` to ensure `initialMorphRelationsObjectMetadataIds` has a stable reference across renders 2. **Added initialization guard**: Used `useEffect` with a `useRef` flag to ensure the default value is only set once during component mount 3. **Maintained Controller defaultValue**: Kept the `defaultValue` prop on the Controller, which now works correctly with the stable memoized value ### Changes - `SettingsDataModelFieldRelationForm.tsx`: Added memoization and initialization guard to prevent default value re-application --------- Co-authored-by: Etienne <45695613+etiennejouan@users.noreply.github.com>
