Hi,

I have created HiddenEntityType (https://gist.github.com/kl3ryk/5781916), to transform value of hidden field into Entity. I was using FormBuilderInterface::getParent() to get Entity class. But in Symfony 2.3 function FormBuilderInterface::getParent was removed. So is there any way to retreive parent form data_class name (https://gist.github.com/kl3ryk/5781916#file-hiddenentitytype-php-L36)?
