Cannot update entity when relation exist

I have an entity representing a user in my system and each user is linked to a comments entity (one-to-many), I have added the comments entity lately and now I noticed that when I update the user entity and the user has comments I get an error, while the user still doesn't have comments everything works fine. I need the related entity only for get the count of comments, I've tried few ways but nothing seems to work.

[2014-12-08 23:31:19] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Form\Exception\StringCastException: "A "__toString()" method was not found on the objects of type "FFS2013\CommentBundle\Entity\Comment" passed to the choice field. To read a custom getter instead, set the option "property" to the desired property path." at /Users/matan/www/FFS2013/vendor/symfony/symfony/src/Symfony/Bridge/Doctrine/Form/ChoiceList/EntityChoiceList.php line 432 {"exception":"[object] (Symfony\Component\Form\Exception\StringCastException: A \"__toString()\" method was not found on the objects of type \"FFS2013\CommentBundle\Entity\Comment\" passed to the choice field. To read a custom getter instead, set the option \"property\" to the desired property path.

I understand that it says he tried to look for the __toString method but I'm don't think this is my real problem. This is the way the relation is configured on the user entity:

@ORM\OneToMany(targetEntity="FFS2013\CommentBundle\Entity\Comment", mappedBy="user", fetch="EXTRA_LAZY")

How can I configured a count property on the user entity and that it will be ignored when updating the entity?

You have added Comments relation as choice field in form, so You should implement method __toString in Comment class to display comments in choice field (object is casted to string, so it must have method __toString). Or set property option (in form builder) with another field used to display in choice widget.
