The ExpressionValidator was incorrectly skipping validation of null or empty string values.
For example the following was (incorrectly) considered valid if hairColour is null because the validator was skipped
```php
<?php
namespace Acme\DemoBundle\Model\Person;
use Symfony\Component\Validator\Constraints as Assert;
class Person
{
private $hasHair;
/**
* @Assert\Expression(
* "!(this.hasHair() and value == null)",
* message="If you have hair you must pick its colour!"
* )
*/
private $hairColour;
}
```
This is a follow on from #11590 but is targeted against master as the BC break introduced was considered undesirable for currently released versions of symfony.
I will squash and create a documentation PR once there is consensus that this is ready to be merged.

README
What is Symfony2?
Symfony2 is a PHP 5.3 full-stack web framework. It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP.
Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
Requirements
Symfony2 is only supported on PHP 5.3.3 and up.
Be warned that PHP versions before 5.3.8 are known to be buggy and might not work for you:
-
before PHP 5.3.4, if you get "Notice: Trying to get property of non-object", you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=52083 and https://bugs.php.net/bug.php?id=50027);
-
before PHP 5.3.8, if you get an error involving annotations, you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=55156).
-
PHP 5.3.16 has a major bug in the Reflection subsystem and is not suitable to run Symfony2 (https://bugs.php.net/bug.php?id=62715)
Installation
The best way to install Symfony2 is to download the Symfony Standard Edition available at http://symfony.com/download.
Documentation
The "Quick Tour" tutorial gives you a first feeling of the framework. If, like us, you think that Symfony2 can help speed up your development and take the quality of your work to the next level, read the official Symfony2 documentation.
