form handling: "bind" is deprecated in symfony 2.3 - "submit" doesn't work either

Question

In symfony 2.3 binding a Request to a form with bind() is deprecated:

$form->bind($this->getRequest());

Now I tried using the submit() method instead (as described in the documentation):

$form->submit($request->request->get($form->getName()));

...but it doesn't work.

The form did not change the object that I added to it upon creation.

Answer 1

Passing the Request directly to submit() still works, but is deprecated and will be removed in Symfony 3.0. You should use the method handleRequest() instead.
