You can also do this for 0 or more Sort-Columns:

List> sortColumns = new LinkedList<>(rooms.getSortOrder());
// rooms.setItems(...)
rooms.getSortOrder().addAll(sortColumns);

The reason why you create a new LinkedList is that you don't wanna just point at rooms.getSortOrder() like this:

List> sortColumns = rooms.getSortOrder();

because this way both rooms.getSortOrder() and sortColumns will become empty after you call rooms.setItems(...) which seems to clear the rooms.getSortOrder().
