The ExpressionValidator was incorrectly skipping validation of null or empty string values.

UPGRADE FROM 2.5 to 2.6
Validator
-
The internal method
setConstraint()
was added toSymfony\Component\Validator\Context\ExecutionContextInterface
. With this method, the context is informed about the constraint that is currently being validated.If you implement this interface, make sure to add the method to your implementation. The easiest solution is to just implement an empty method:
public function setConstraint(Constraint $constraint) { }
-
Prior to 2.6
Symfony\Component\Validator\Constraints\ExpressionValidator
would not execute the Expression if it was attached to a property on an object and that property was set tonull
or an empty string.To emulate the old behaviour change your expression to something like this:
value == null or (YOUR_EXPRESSION)
