Field validation fails when a datetime object is used within a table.

datetime field in a table

// works
$form['foo'] = [
  '#title' => $this->t('Foo'),
  '#type' => 'datetime',
];
$form['sleep']['days'] = [
  '#type' => 'table',
  '#header' => ['#markup' => 'Header']
];
// fails
$form['sleep']['days']['bar'] = [
  '#title' => $this->t('Bar'),
  '#type' => 'datetime',
];

No idea if this is the right way to go.

The issue is in core/lib/Drupal/Core/Form/FormBuilder.php, around line 1298, at the end of FormBuilder::handleInputElement().

// Set the element's value in $form_state->getValues(), but only, if its key
// does not exist yet (a #value_callback may have already populated it).
if (!NestedArray::keyExists($form_state->getValues(), $element['#parents'])) {
  $form_state->setValueForElement($element, $element['#value']);
}

The issue is that the parent table element has already been run through the FormBuilder::handleInputElement method and set a value, and so NestedArray::keyExists returns TRUE. So in worrying that a #value_callback may have already set a value, we prevent values generated by a #value_callback from setting properly.

I tested this theory by removing the if statement and just letting

$form_state->setValueForElement($element, $element['#value']);

run. It worked fine.

Seems #18 had some failures.

Version: 9.5.x-dev » 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

Version: 11.x-dev » main

Drupal core is now using the main branch as the primary development branch. New developments and disruptive changes should now be targeted to the main branch.
