TYPO3 Core

With #70370 the placeholders are processed by a DataProvider. The processing of configurations like this

'config' => array(
                'placeholder' => 'LLL:EXT:filemetadata/Resources/Private/Language/locallang_tca.xlf:placeholder.keywords'
            ),

are not respected.

Same goes for embedded FlexForms that use a LLL placeholder.

We have both cases in the core. The above example is taken from the keywords field of sys_file_metadata. Both combined can be foun in the TCA for sys_file_storage.

To verify the patch, just create anew File Storage and switch to the second tab. Field "Base path" is a FlexForm field with LLL placeholder and field "Folder for manipulated and temporary images etc" is just a normal TCA input field.
