Bug: Unsetting a revoked object permission keeps it revoked
When a role has a global permission enabled (e.g.
canReadAllObjectRecords: true) but an object-level override revokes it
(canReadObjectRecords: false), clicking to remove that override had no
effect — the permission stayed revoked after save.
Root cause:
Backend (object-permission.service.ts): The nullish coalescing operator
(??) was used to fall back to the current DB value when the input didn't
provide a value. Since ?? treats both null and undefined as nullish,
sending canReadObjectRecords: null (meaning "remove override") was
coalesced to the current value (false), silently discarding the reset.
Fix:
- Backend: Replaced ?? with explicit !== undefined checks, so null is
preserved as a meaningful value (meaning "no override / inherit from
global") while undefined (field not provided) still falls back to the
current value. This also fixes the "Reset all permissions" flow which
sends null for all permission fields.
Additional frontend fix: Changed !value to value === false so that only
an explicit false cascades revocation to write permissions. Setting null
(reset to inherit) now only affects the read permission itself.
