after $form->setAction(), destination presenter throws exception

[iinfo-dev-mk]

In version 2.2:

I have PageWithFormPresenter::actionDefault with this code

$form = $this["orderForm"];
$form->setAction($this->link(":Result:", "paramValue"));

/**
* @return UI\Form
*/
public function createComponentOrderForm() {
}

When form is submitted to destination url, presenter which serves this url (ResultPresenter) throws the BadSignalException with "The signal receiver component 'orderForm' is not found".

This worked without any error in 2.1. It's related to change in form submit url and "do" parameter in POST data, which was introduced in 2.2

I wonder what is a use case for this...
Anyway, you should be using Nette\Forms\Form, not Nette\Application\UI\Form, if you want to mess with form behavior and not use automatic signal-driven submitting.

What I observe, the reason for such use case is avoiding session usage. If form handling is made in same presenter session is needed.

Maybe replacing UI\Form with Form\Form will enough, I don't know, thank you for tip anyway.

The main problem is that use case worked fine in 2.1 and doesn't work in 2.2. We have many forms with setAction and it's time consuming to verify all these places. This is definitely BC break.

And finally there is currently (in 2.2+) no sense to use setAction in Ul\Form. Mostly - if another then "this" presenter is used - it doesn't work, throws exception. Solution can be disabling the call setAction in UI\Form anyway or throw exception. I think current behavior needs some adjustment.

It this use case you should definitely use Nette\Forms\Form instead of UI\Form.
