I believe DateConverter should be changed to something like the following to 
handle nulls or bad string 
parsing

        override public function toString(obj:Object):String
        {
            var date:Date = obj as Date;

            if (date && !isNaN(date.time))
            {
                return (String(date.fullYear+"-"+addLeadingZero((date.month+1))+"-
"+addLeadingZero(date.date)+" 
"+addLeadingZero(date.hours)+":"+addLeadingZero(date.minutes)+":"+addLeadingZero
(date.seconds)+"."+da
te.milliseconds));
            }
            else 
            {
                return null;
            }
        }
        public override function fromString(value:String):Object{
            var date:Date = null;

            if (value && value.length > 0)
            {
                date.setFullYear(Number(value.substr(0,4)), Number(value.substr(5,2))-
1,Number(value.substr(8,2)))
                date.setHours(Number(value.substr(11,2)), Number(value.substr(14,2)), 
Number(value.substr(17,2)), Number(value.substr(20,3)));

                if (isNaN(date.time))
                {
                    date = null;
                }
            }

            return date;
        }
