RenderElement and FormElement base plugin classes are deprecated in 10.3 and removed in 12.0

class_alias should allow us to work with both versions.

Thanks. I will use it in my other modules, too, like workflow module.

Oh,
is there a backslash missing?

if (class_exists('\Drupal\Core\Render\Element\FormElementBase')) {
  class_alias(
    '\Drupal\Core\Render\Element\FormElementBase',
    'Drupal\office_hours\Element\FormElementBase'
  );
}

bluegeek9 → changed the visibility of the branch 8.x-1.x to hidden.

is there a backslash missing?

Good Question!

I tested it, both work. I added the slash.
