merged branch Burgov/enhance_form_error_message (PR symfony#4557)

Commits ------- b5cf337 [Form] Enhanced the form error message Discussion ---------- [Form] Enhanced the form error message Bug fix: no Feature addition: yes Backwards compatibility break: no Symfony2 tests pass: yes The error message on type mismatch is a bit obscure: The form's view data is expected to be an instance of class Samson\Bundle\TRSBundle\Entity\Labour, but has the type object. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms object to Samson\Bundle\TRSBundle\Entity\Labour. This commit changes it to: The form's view data is expected to be an instance of class Samson\Bundle\TRSBundle\Entity\Labour, but is an instance of class Closure. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms an instance of Closure to an instance of class Samson\Bundle\TRSBundle\Entity\Labour. --------------------------------------------------------------------------- by travisbot at 2012-06-12T14:04:08Z This pull request [fails](http://travis-ci.org/symfony/symfony/builds/1601478) (merged 70a15df6 into 7783969). --------------------------------------------------------------------------- by travisbot at 2012-06-12T14:06:31Z This pull request [fails](http://travis-ci.org/symfony/symfony/builds/1601507) (merged 12ec4dbd into 7783969). --------------------------------------------------------------------------- by travisbot at 2012-06-12T14:13:09Z This pull request [passes](http://travis-ci.org/symfony/symfony/builds/1601517) (merged b5cf337 into 7783969). --------------------------------------------------------------------------- by bschussek at 2012-06-12T18:21:31Z :+1: Thanks!
