TYPO3 Core

I can confirm this issue. But I think it is more an IRRE Bug than a FAL related issue?!

Looking a little into this issue I think the reason why it doesn't work in Extbase is because the FAL API doesn't use proper TYPO3 API to get file references. I looks like it would work fine if you use the TypoScript objects to fetch your references because the ContentObjectRenderer's getImgResource uses FAL's ResourceFactory to fetch the file reference. The method getFileReferenceObject in the ResourceFactory uses the page repository's checkRecord method, which does not check language and therefore bypassing the language field. However Extbase uses the it's own SQL parser which follows all the rules defined in the sys_file_reference's ctrl configuration, and therefore adds the language check.

http://api.typo3.org/typo3cms/master/html/_resource_factory_8php_source.html#l00440

So IMO it's related to FAL since FAL bypasses the ctrl configuration, but there are of course more than one solution, either one specifically for Extbase and one for handling languages for sys_file_references property. Thing is though that the references are copied when an element is translated instead of it using the normal inline translation workflow, so maybe it doesn't even make sense to have localized versions of sys_file_references.

Added a dependency to an IRRE issue #21964, which is... 4 years old.

I have the exact same behaviour and brings much trouble in multilingual sites...
Does anyone have a clue how to workaround this?

I can confirm that this issue still exists in 6.2.3 (unfortunately can't try out 6.2.4 atm)

1) Create new Parent Record (set sys_language_uid > 0)
2) Create Image-IRRE-Relation (sys_file_reference) -> sys_language_uid field is in hidden palette "filePalette" and of course defaults to value "0" (if no other default value is set)

3) Result: Parent Record has sys_language_uid > 0.. Child Record in sys_file_reference has the value "0" as you can't change it by default...

The problem also still seems to exist for already existing parent records.

@Jan Schröder Greth:
For now, one option is to make the palette visible via extTables.php, and then at least be able to configure the sys_language_uid field manually:

$TCA['sys_file_reference']['palettes']['filePalette']['isHiddenPalette'] = 0;

But if I create a new element in non-default language (sys_language_uid = 1) the attached FAL image is not recognized by extbase.

Do you create a new record through extbase or backend?
Can you provide a simple test extension and describe steps to reproduce it?

Steps how to reproduce:

- create a page_language_overall for a page
- insert a new content element "text & media"

case 1:
- save the content element
- add an image to media tab (assets field)
- save the content record again

expectation:
- sys_file_reference record is stored with proper language in sys_language_uid

actual:
- sys_file_reference record is stored with sys_language_uid 0

case 2:
- add an image to media tab (without saving the parent content record)
- save the content record

expectation:
- sys_file_reference record is stored with proper language in sys_language_uid

actual:
- sys_file_reference record is stored with sys_language_uid 0

Few notes:
1) Now NEW irre elements (including FAL relations) will get a sys_language_uid of their parent.
2) There is no automatic migration of the old record having inccorrect value in the sys_language_uid.
3) The issue has been solved on the FormEngine level, thus you need to make sure you have
sys_language_uid field in the showitem list in your TCA.

Often you don't want to show the sys_language field to the user, so there is a little trick, which will make stuff work without showing the field to the user.
You just need to create a hidden palette with sys_language_uid in it.
e.g.

'showitem' = '... --palette--;;hiddenLanguagePalette,';
'hiddenLanguagePalette' => [
    'showitem' => 'sys_language_uid, l10n_parent',
         'isHiddenPalette' => true,
],
