Populating param entity

[kanonhian]

In Symfony + twigg

/*@Route
*/@Method('POST')
public function createEntityAction(Request $request, Entity $entity)

this code populates $entity with the form data shipped in the request, with no need to code nothing.

What happens is that I am developing a web api, so there is no twigg or server side templates generation, all is done in the client with ExtendJS. So, my question is :may I achieve the above's behavior with this bundle? If not, please tell me if exists any other vender that gets the job done. I can perfectly code it, just i dnt want to remake the wheel.

Sorry for my english and thanks for this bundle.
