setOptionsStringLanguages() does not works (setOptionsString works, but only for default one, with translations...)

[Cybermano]

Hi everybody,

I'm trying to translate options into already activated languages, via hook: setOptionString works correctly for the default language, but I can't populate the options in other languages.
More specifically, changing the user profile language the titles are translated, but the options are overwritten in the "default" language tab.

So I have found the setOptionsStringLanguages method, but it seems to break someting (I have an error like: ProcessPageEdit:Multi language not enabled.. of course it's enabled)

The scenario is a hook for an inputfield:render

Spoiler

$wire->addHookBefore('InputfieldSelect::render', 'optionPopulate');

function optionPopulate($event){

    $inputfield = $event->object;
    if ($inputfield->name != "MY_FIELD_NAME") return;

    $pages = wire('pages')->find('template=MY_TEMPLATE, sort=sort, registration=1');

    // Set the groups in the field
    $field1 = wire('fields')->get('MY_FIELD_NAME');
    $field1->useLanguages = true; // It seems to do nothing (?)
    $manager1 = new SelectableOptionManager();
    $langOptions = [];
    foreach (wire('languages') as $lang) {
        $options = '';
        $langOptions[$lang->id] = '';
            foreach ($pages as $p){
                $options .= $p->id . '=' . ($p->getLanguageValue($lang->id,'title') ?? $p->title.$lang->id).'
            ';
            }
        $options .= '99=' . __('Independent', '/site/templates/transaltions/front_end.php').'
        ';
        $langOptions[$lang->id] = $options;

        // SECOND APPROACH: FORCING OPTION BY EACH LANGUAGES, BUT DO NOTHING
        // wire('user')->laguage = $lang;
        // $manager1->setOptionsString($field1, $langOptions[$lang->id], true);

    }
// FIRST APPROACH: PageEdit Error: MultiLanguage Support not activated (???)
$manager1->setOptionsStringLanguages($field1, $langOptions, true);
}

 

Any suggestion?

Thanks in advance.
