php - Problems with ValidatorConstraint in Symfony 2.5

Question

after upgrading from Symfony 2.4 to 2.5 my form validator constraints are not working any more.

I get: Catchable fatal error: Argument 1 passed to SymfonyComponentFormExtensionValidatorTypeFormTypeValidatorExtension::__construct() must be an instance of SymfonyComponentValidatorValidatorInterface, instance of SymfonyComponentValidatorValidatorRecursiveValidator given, defined in vendor/symfony/symfony/src/Symfony/Component/Form/Extension/Validator/Type/FormTypeValidatorExtension.php on line 36

Anybody has a suggestion how to fix this?

Try setting the validation api in your config.yml.

Comment from the UPGRADE-2.5.md
https://github.com/symfony/symfony/blob/master/UPGRADE-2.5.md

"The validation engine in SymfonyComponentValidatorValidator was replaced by a new one in SymfonyComponentValidatorValidatorRecursiveValidator. With that change, several classes were deprecated that will be removed in Symfony 3.0. Also, the API of the validator was slightly changed. More details about that can be found in UPGRADE-3.0.

You can choose the desired API via the new "api" entry in app/config/config.yml:"

framework: validation: enabled: true api: auto
