Breaking: #87989 - TCA option setToDefaultOnCopy removed

See forge#87989


The special TCA option $TCA[$tableName]['ctrl']['setToDefaultOnCopy'] is removed.

It allowed to reset a certain field to its default value when copying a record.


Having the setting set in TCA will trigger a PHP E_USER_DEPRECATED error when building TCA.

Copying records with this TCA setting enabled, will now keep the copied state and avoid side-effects.

Affected Installations

TYPO3 installations with active usage of sys_action or other extensions using this TCA setting.


This option was only there for resetting some sys_action values to default, which can easily be achieved by a hook if needed. If an extension author uses this setting, this should be achieved with proper DataHandler hooks.
