Default Detect when a spark Scroller is changing scroll position

ActionScript Code:
<s:Scroller right="0" left="0" top="0" bottom="0" > <s:horizontalScrollBar> <s:HScrollBar id="hbar" change="bottomscoller_hScrollBar_change(event)" /> </s:horizontalScrollBar> <s:HGroup gap="0"> ....stuff here </s:HGroup> </s:Scroller>

then i have that function "bottomscoller_hScrollBar_change" but it never gets called.

anyone know how to find out when this scroller has been scrolled?

I used the flash.events.Event.RENDER event to determine if the spark Scroller has been scrolled/repositioned

a pretty bad listener to be doing "if" statements inside. anyone know a better idea?

what does this mean? "This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event."

Just incase you were uneasy about implementing such a hacky solution, you did in fact stumble across a design flaw (or possibly a bug based on the docs).

Basically the only thing you can do is periodically "probe" the current scroll position. How you do this is up to you (EG. render event).
