The fundamental problem isn't a non-broadcast event, its that a non required NumberValidator, as designed, will not return an error state if a string is passed to it. This doesn't meet my needs on my current (or likely any), project. I've sub-classed it so that even when its non-required, it will show an error state if the element in question is a string in not a number (NaN).
I know in previous versions of flex, the number validator behaved as I expected, and was easily capable of showing a "Not a number" error, whether or not the field was required, which was the cause of my concern. The fix was easy enough (~30 line sub class), so its no big deal.
