The current code is correct, it's invoking a method from the object being validated, what you're doing here is different.

Edit : nevermind, I tought it was from the first example :)

I know that the current code is right, but this section of the doc explains how to validate with static method, all the other examples (YAML, XML and Annotation) are right, but php no.

See http://symfony.com/doc/current/reference/constraints/Callback.html#methods.

Looks good but you should base this on the 2.2 branch.
