I was able to work around the missing openItems by listening to the
itemOpen and itemClose events and store the array on my own.
public function listenToOpenings(event:AdvancedDataGridEvent) : void {
openItems.push(event.item);
}
public function listenToClosings(event:AdvancedDataGridEvent) : void {
openItems = openItems.filter(function
filterOpenList(currentElement:*, index:int,arr:Array) : Boolean {
return currentElement != event.item;
}) as Array;
}
I'm still curious what the logic behind removing it was. Is there a
new/different way to track open nodes now?
