Description

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 change over time.
