**Symfony version(s) affected**: 4.3.0 **Description** In one of my forms I receive this error: > Property "domain" does not exist in class "App\Entity\MyEntity" Obviously it doesn't exist as the property is actually `$domains`. So I have a method `addDomain` and a method `removeDomain`. The problem is caused by the validation `auto_mapping`: if I disable it, the problem disappears ```yaml framework: validation: email_validation_mode: html5 # Enables validator auto-mapping support. # For instance, basic validation constraints will be inferred from Doctrine's metadata. #auto_mapping: # App\Entity\: [] ```
