Bug #104760
Updated by Torben Hansen 3 months ago
When TCA configuration for a field defines a @label_userFunc@, the @FlexFormValueFormatter@ may throw an undefined array key exception, if the flexform data saved in @sys_history@ table does not match the expected flexform data structure. This problem might occur on TYPO3 websites, where the structure of flexform for a relation table field having a @label_userFunc@ did dis change over time.
