If a party is required or permitted to plead further by an order or ruling, the clerk shall forthwith mail or deliver notice of such order or ruling to the attorneys of record. Unless otherwise provided by order or ruling, such party shall file such further pleading within ten days after such mailing or delivery; and if such party fails to do so within such time, the party thereby elects to stand on the record theretofore made. On such election, the ruling shall be deemed a final adjudication in the trial court without further judgment or order; reserving only such issues, if any, which remain undisposed of by such ruling and election.
