I am having all sorts of problems with removing items from an
XMLListCollection. Not sure if this is because the dataBinding is
preventing the items from being removed or not - I'm hoping someone
who has run into this issue as well can give me some insight.
I have 2 XMLListCollections, each 1 is bound to a seperate DataGrid.
There is an approvedItemList bound to dgApproved, and an
unApprovedList bound to dgUnApproved.
Sometimes, I want to remove an object from the 1 list, and then add it
to the other list. (I am using Cairngorm by the way)
For example, I want to take an item in the unApprovedList and add it
to the ApprovedList. So first I would add the object to the
ApprovedList, and then get the Index of the object in the
UnApprovedList and use RemoveAt like so:
approvedList.addItem(myObject);
var index:int = unApprovedItemList.getItemIndex(myObject);
unApprovedList.removeAt(index);
I am looking at the collections in the watch window, and I can see
that when the .removeAt fires, the object is still left in the
unApprovedList! Why is this happening?
I then attempted to remove the item this way as a workaround:
approvedList.addItem(myObject);
var index:int = 0;
for each(var o:Object in unApprovedList){
if(o.Id == myObject.Id.toString()){
delete o[index];
break;
}
else
index++;
}
Here again, when the delete command gets hit, the line executes, but
the object is left in the collection. I am left with 2 copies, the
newly added one in the approvedList, and the leftover copy that I've
tried to delete in the unApprovedList.
Is the databinding somehow making a copy or "locking" that object?
