The problem is that you have two nameless forms (input names like inputname instead of formname[inputname], and thus when you bind the request to your form and it gets validated it detects some extra fields (the other form) and so it is invalid.

The short-term solution is to create a named builder via the form factory, so instead of:

$form = $this->createFormBuilder(null)

you should use:

$form = $this->get("form.factory")->createNamedBuilder("my_form_name")

The long term solution would be to create your own form classes, that way you can keep your form code separate from the controller.
