Why I don't have the 'formatter' attribute in my Symfony2 Form?
===

I was wondering, since an update of Symfony2.1 (I can't target the commit though) why I no longer have the `"formatter"` attribute on my `jQueryDateType`

    if ($form->getConfig()->hasAttribute('formatter'))

returns `false`

The whole class is here : https://gist.github.com/d3c74c12d60e20df84c3

Thanks.
