There is an error whith custom translation entity when i launch doctrine:generate:entities
No identifier/primary key specified for Entity 'Allblacks\MyBundle\Entity\MyTranslationEntity'. Every Entity must have an identifier/primary key.
As explained many times in previous issues here, this is a bug in the Doctrine EntityGenerator which does not handle inheritance properly. Nothing that can be solved in the bundle. If you want to use the generator tool, disable the mapping for the bundle (as explained in the doc) when running the command and enable it again after that.
