When trying to access the cookbook article [How to use the Virtual Form Field Option](http://symfony.com/doc/2.2/cookbook/form/use_virtuals_forms.html) (for example by using the link in the [form Field Type reference](http://symfony.com/doc/2.2/reference/forms/types/form.html#virtual)) one is always redirected to the [inherit_data option article](http://symfony.com/doc/2.2/cookbook/form/inherit_data_option.html) (which doesn't exist in 2.2).
