hello, you can pass the value in callback:
in create:
protected function saveFrom(Form $form)
{
$this->onSave($form->values->parameter);
}
in presenter:
protected function createComponentCityForm()
{
$cityForm = $this->cityFormFactory->create( $this->currentCity);
$cityForm->onSave[] = function (int $parameter) {
$this->redirect('Cities:seznam', $parameter);
};
return $cityForm;
}

Look into your CityForm class and wherever $this->onSave()
is
called, all of the parameters that are passed to the call can be used in the
callback in presenter. That means if there is somethign like
...
$formValues = ['gps' => 'here&there', 'name' => 'Kocourkov'];
$this->onSave($id, $formValues);
...
in your presenter you get to access that data by doing something like
$cityForm = $this->cityFormFactory->create( $this->currentCity);
$cityForm->onSave[] = function ($cityId, array $data) {
$this->alert("City $data[name] has been updated");
$this->redirect('Cities:detail', $cityId);
};
Take a note that only the order of parameter must match, their names are merely informative here

Huh, I see. I didn't quite get what you meant by the part
In create: ...
and I thought your inquiries about the factory
wouldn't lead thcom to the solution quite as concisely.
I believe we are all talking about a form-wrapping component so I also tried to push thcom to examine the code “behind” the callbacks and make sense out of it for themselves.
