Description

Steps to reproduce:

1. Create an invalid Date. Like date = new Date("01/01/AAAA");
2. Affect this date to a DateField. dateField.selectedDate = date.
3. You will never be able to change the date of this DateField anymore.

Why?

DateField now compares the date if it changes.

public function set selectedDate(value:Date):void

{ if (ObjectUtil.dateCompare(_selectedDate, value) == 0) return; .... }

Since the Date is invalid, all fields are NaN.

ObjectUtil dateCompare will take the getTime() wich will return NaN.

The NaN comparator with a Number is always returning false, so the compare will always return 0. And you will never be able to change the selectedDate.
