Bug #96995
opennon-numeric value while the value diff is calculated
0%
Description
In the BackendUtility a "non-numeric value" error (or a warning) is thrown when trying to translate/edit the translation of a content item if it contains a TCA field of type "check" with multiple items. The reason seems to be that the class TYPO3\CMS\Backend\Form\FieldWizard\DefaultLanguageDifferences
wants to access the field defaultLanguageDiffRow
from $data
(filled by the DataBaseLanguageRows
FormDataProvider), but there are only empty strings in it.
Inside BackendUtility
the $value is compared without checking for numeric value or casting it first.

If the value is casted to an int in the backend utility, the error no longer occurs. I don't know if this is the right way or if it is better to check if it is a numeric value. With the patch in the attachment, the error no longer occurs.
