/** Finds and stores referenced action to be invoked after the actor is fully initiated. As opposed to
 * {@link OnCloseLmlAttribute}, these actions are invoked after actor object is fully constructed, rather than the tag
 * is closed, so the widget will not contain its children and will not have yet parsed its plain text between tags.
 * Multiple on create actions can be referenced with different attribute names, but their invocation order is not fixed,
 * so they should not depend on each other. This attribute expects an action ID. By default, mapped to "onCreate",
 * "create", "onInit", "init".
