| Q | A | ---------------- | ----- | Bug report? | no | Feature request? | yes | BC Break report? | no | RFC? | yes | Symfony version | 3.4 The `DoctrineOrmTypeGuesser` guesses the type of properties by their Doctrine annotations. The `simple_array` and `json_array` types are missing: https://github.com/symfony/symfony/blob/v3.3.8/src/Symfony/Bridge/Doctrine/Form/DoctrineOrmTypeGuesser.php#L55-L56 Symfony currently uses `doctrine/dbal: ~2.4` which supports `simple_array` as well as `json_array`: https://github.com/doctrine/dbal/blob/v2.4.0/lib/Doctrine/DBAL/Types/Type.php#L37-L38 Will this be accepted if I create a pull request?
