Hi Richard,
How are you refreshing the ArrayCollection? If you are doing something like
this:
oldArr = newArry;
then its not going to work because of the way binding works. If you haven't
done it already, try this:
oldArr.removeAll();
for(var i:int=0; i<newArr.length; i++){
oldArr.addItem(newArr.getItemAt(i));
}
Good luck!
