I would have agree with the jonkster. And it's pretty easy to demonstrate a departure of control by using opposite aileron at the point of stall.
Have a look at this video and see what the pilot does with the yoke right at the point of stall:
Let's not forget the primary function of a basic flap - as opposed to an aileron - is to increase the surface area of the wing to increase lift for the same speed - the penalty being drag. The change in chord line merely facilitates a lower nose attitude for a better view during approach.
As far as I'm aware, ailerons (not flaperons) do not change the lift coefficient of the wing in the same manner flaps do. In addition, there seems to be a bit of confusion about the reference point of AoA in relation to flaps. Flaps change the chord line, so if you do not alter the point of reference of AoA for a clean wing, then of course the AoA of the wing as a whole will decrease. But the stalling AoA of the chord line in reference to the relative airflow is still the same.
As for the application of flaps at the point of stall, this has been addressed by at least one person who claims to have tried it in a Chippy:
