ids not generated for hidden inputs about forms

[dg]

To look in history https://github.com/nette/forms/commits/master/src/Forms/Controls/HiddenField.php is probably faster that to create this issue.

It is experimental.

Once again it becomes clear that dependency on generated IDs is good candidate for refactoring :).

well, tell to that guy who coded that before me :) refactoring is best done one step at a time, not all at once

btw, what's the reason for this change? i don't think it helps anything or that it would be problematic. it's just harmless and i would guess there would more apps out there that depend on it

i'm for keeping it, like it was in 2.2

btw, $form['items']->getHtmlId() still returns the generated id, shouldn't it return NULL then?

@bazo Did that guy also decided to migrate code instead to next stable to @dev again or was that you?

[bazo]

and how is that relevant? that was an answer to vojtech. i've already fixed that.
but i'm just asking what advantage this change has?
