The documentation for ListChangeListener.Change suggest the following code:
{code}
ObservableList<Item> theList = ...;
 {
     theList.addListener(new ListChangeListener<Item>() {
         public void onChanged(Change<Item> c) {
             while (c.next()) {
                 for (Item remitem : c.getRemoved()) {
                     remitem.remove(Outer.this);
                 }
                 for (Item additem : c.getAddedSubList()) {
                     additem.add(Outer.this);
                 }
             }
         }
     });
 }
{code}
But this will not work because c.next() returns false if there was only one change.
See attached example.
