Symfony2 – ErrorException: Notice: serialize() [function.serialize]: “xxx” returned as member variable from __sleep() but does not exist in …

While storing an entity from Doctrine2 in the session under a Symfony2 application I got this error:

ErrorException: Notice: serialize() [function.serialize]: "entity_property" returned as member variable from __sleep() but does not exist in ...vendor/symfony/symfony/src/Symfony/Component/HttpKernel/DataCollector/DataCollector.php line 27

This error was happening because my “entity_property” was declared as private and PHP has some issues serializing objects that subclass a class with private properties. Just changing that “entity_property” to protected (as it should always have been…) solver the error.
