A couple of days ago I discovered that this 'event' fires every time
the row is scrolled into or out of view. So if you are scrolling
quickly, this code could be firing tens of times just over a half
second or whatever. Setting a flag is definitely a good idea. Here is
what my code ended up looking like (itemRenderer was just a checkbox
with a dynamic label):
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(super.data[q] != str_label)
{
cb_planNumber.label = str_label = super.data[q];
cb_planNumber.selected = false;
}
}
