Ajax callback on parent element is "cut" down

Open on Drupal.org →

I don't know, if this is a bug, support or feature request.

My setup:
I've created a custom FormElement which generates a wrapper containing some textfields.

  • added the #process => 'processAjaxForm' entry in getInfo()

Next I define the #ajax setup in my form array.

class AjaxTestForm extends FormBase {
  public function buildForm(array $form, FormStateInterface $form_state) {
    $form['my_ajax_field'] = [
      '#type' => '',
      '#ajax' => [
        'callback' => array($this, 'ajaxFoo'),
        'event'    => 'change',
        'progress' => array(
          'type'    => 'throbber',
          'message' => t('Verifying value'),
        ),
      ],
    ];
    $form['submit'] = [
      '#type'  => 'submit',
      '#value' => 'go',
    ];

    return $form;
  }

  public function ajaxFoo(array $form, FormStateInterface $form_state) {
    var_dump($form_state->getTriggeringElement());
    die;
  }
}

Unfortunately no form values get submitted on the ajax request. ($_POST parameters for all form elements are missing.
Is this working as expected, or am I missing anything in the FormElement class?
My workaround for now is, adding the #ajax setup to the descendant fields and unsetting it for the #parent element.

Besides, the error message saying "reached max_upload_filesize" is a bit strange here. And there is no point of debugging/investigating this kind of error, because no error.log or watchdog entry is created.
But I guess this is used to handle "hacky" form submissions.

    There has been no discussion here for 8 eight years. And it seems that #2 answers the question, but I don't know the form system.

    Since we need more information to move forward with this issue, I am setting the status to Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

    Thanks!

    There has been no response to confirm that this is still an issue, therefor closing.

    If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue → (starting from "Install Drupal core").

    Thanks!
