I was looking for a way to create a no-maximum NumericStepper and came up with
the idea of listening to the Change event and just upping the maximum value by
1-stepSize unit above the current value.
The only thing was, I needed to use a callLater() in order to change the
maximum or else the change didn't take effect in time.
So I would suggest a listener on each, in which you would calculate the new
maximum of the "other" two steppers, then perform a callLater that looks like
this:
callLater(resetMaxValues, [newMaxValue, stepperA, stepperB])
... and then something like this:
private function resetMaxValues(newMaxValue:int, stepperA:NumericStepper,
stepperB:NumericStepper):void
{
stepperA.maximum = newMaxValue;
stepperB.maximum = newMaxValue;
}
