XMLListCollection."refresh" is not intended to work in this case.  "refresh"
just causes the filter or sort to be re-applied.  If it works to refresh the
UI, it is by accident.

 

The documented way to handle this issue is to use the collection API to make
the update, or, if you directly set a property on an item, call
collection.itemUpdated(item)
