TYPO3 Core

I get an error while inserting new elements on a workspace with a self-written extbase extension, when I configure TCA[ctrl][label] to an integer field.

Error Message: 102: These fields are not properly updated in database: (weekday) Probably value mismatch with fieldtype.

Although an error mesage is shown, all fields get properly inserted and updated in DB.

This happens only on a draft workspace not on live workspace. This error happens only, when the label is mapped to an integer field in DB. When I change the label mapping to a varchar field in DB, no error occurs.

Looking through the code, the error occurs in function checkStoredRecord in class.t3lib_tcemain.php, Line 6159 ff.

There are also some forum entries regarding this problem, for example:

Parts of my TCA configuration:

$TCA['tx_iostorefinder_domain_model_openinghours'] = array (
'ctrl' => array (
'title' => 'LLL:EXT:io_storefinder/Resources/Private/Language/locallang_db.xml:tx_iostorefinder_domain_model_openinghours',
'label' => 'weekday',
'tstamp' => 'tstamp',
'crdate' => 'crdate',

'languageField' => 'sys_language_uid',
'transOrigPointerField' => 'l18n_parent',
