When I don't provide any of the translatable properties through my submit form, then I get no validation checking, even when I have implemented:
/**
* @Assert\Valid
*/
protected $translations;
In config.yml I have:
default_locale: cs
required_locales: [cs]
All topics about this problem were giving importance on the @Assert/Valid on $translations property, which I have implemented (I have even tried validation.yml configuration).
Now I realise, that I forgot to add, that I am displaying and submiting the form through Easy Admin bundle. I am not building the form myself. Just configuring Easy Admin settings for my entity. Maybe there's some glitch.
