Test translation

@Grevil: Any idea how to get the translated config per user?

    // @todo: We need to get the config in the users language!
    $escalationStepConfig = $this->getEscalationStepConfig($escalationStep);

Currently, the mails are always sent in one language...

I was searching for a solution for half an hour without valid results. This MUST be possible? xD

Alright, I implemented this similar how, the user module does it: https://git.drupalcode.org/project/drupal/-/blob/11.0.x/core/modules/use...

But it doesn't seem to work. Maybe there is some kind of caching issue? Assigning this to @anybody for further investigations.

NOTE @anybody. For some reason there is NO hook_mail() implementation anymore for 11.x !!!

I just stumbled upon this, while looking into the user module online. Maybe there is a cleaner way on how to do this now! Please have a look at https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/user/....

NOTE @anybody. For some reason there is NO hook_mail() implementation anymore for 11.x !!!

The reason is:

Thank you, I'll check why it doesn't work. Code looks correct to me, now we know that core does it the same way!

Okay seems I'm close to the reason why it doesn't work:

\Drupal::config('user_registration_reminder.settings')->get("reminder_escalations.0")

works as expected and returns the German string at the same place, while

$escalationStepConfig = $this->getEscalationStepConfig($escalationStep);

doesn't and returns the English string.

So I pretty much guess this is another reason why we shouldn't use this convenient anti-pattern:

$this->config = $configFactory->get('user_registration_reminder.settings');

@Grevil: That's it!!!!!! CRAZY. Interesting to see this heavy side-effect...

Nice! Good find!!!
