This is not a similar issue since the AAdvantage rules are very different to QFF
In the AA rules for CX earning it does say
"Cathay Pacific codeshare flights operated by any oneworld Alliance member airline are eligible for mileage accrual when purchasing an eligible fare."
so by implication codeshare flights on non OW do not earn miles
