Breaking: #82709 - TCA option "localizeChildrenAtParentLocalization" removed

See forge#82709


The TCA option $TCA[$tableName]['columns'][$columnName]['config']['behaviour']['localizeChildrenAtParentLocalization'] has been removed, as this is the default behaviour for any kind of inline translation (IRRE).

The behaviour to disable this functionality in TYPO3 v8 was not compatible anymore with any localization mode setting and the newly introduced allowLanguageSynchronization.


Explicitly disabling this option has no effect anymore, setting this option in TCA will trigger a deprecation message.

Affected Installations

Any installation with custom TCA definitions of Inline Relational Record Editing which have this setting set.


Remove the TCA option in the extensions' TCA definition.
