OK, putting a small flag into the function that checks to see if the
data is actually new seems to be a decent way around the firing when
scrolling, but it feels kinda dirty and hackish.
private var str_label:String;
override public function set data(value:Object):void
{
use namespace DOCUMENT_METADATA_NAMESPACE;
var q:QName = new
QName(DOCUMENT_METADATA_NAMESPACE, "PlanNumber");
super.data = value;
if(data[q] != str_label)
{
cb_planNumber.label = str_label =
data[q];
cb_planNumber.selected = false;
}
}
Can someone, ideally from Adobe, confirm or deny my thought that the
event being dispatched on scroll is a bug?
Thanks,
Ben
