The court of appeals affirmed that judgment, concluding that Cavnar made a specific pleading for prejudgment interest unnecessary. 722 S.W.2d 744 (Tex.App. 1986). Subsequent to the court of appeals' opinion, this court held that "although we intended Cavnar to apply to all cases still in the judicial process, we did not dispense with the pleading requirement for prejudgment interest sought at common law, nor did we suspend Rule 301, which requires the judgment to conform to the pleadings.
