Description
The current implementation in the TYPO3 backend does not allow to store NULL values, only empty strings or zero as number are allowed.
Since the overlay behavior of FAL takes e.g. the description property from the original file object an empty value in the disposal (the referenced file) cannot be defined to be blank, thus not clearing the original file description.
For this case we need a new behavior to allow NULL values in the storage and to handle that in the backend view.
For this a new TCA eval property needs to be created null, e.g.
'config' = array(
'type' => 'input',
'eval' => 'null',
...
);
