A quick tip if you have a dynamic scroll bar and want to bind it’s maxScrollPosition to a value at runtime unfortunately you can’t use the MXML binding, i.e. maxScrollPosition={value}.

Alternatively you need to set the value programatically in an event handler, AND importantly call updateDisplayList() on the scrollbar. i.e.

 
                <!--[CDATA[
                        private function handleSlideChange():void {
                                scroll.maxScrollPosition = slider.value;
                                scroll.invalidateDisplayList();
                        }
                ]]-->
