Funny you should ask about this - I just blogged about SortedList and
TableView the other day, over at FXExperience:
http://fxexperience.com/2013/08/returning-a-tableview-back-to-an-unsorted-state-in-javafx-8-0
Of course, I can see that you've already read that post (I see a comment
from the code in my post in your code below). What might have been
missed is that I noted earlier on in the blog post I had to make a few
small changes to properly get SortedList support in TableView, so you'll
want to try again in b102 (or b103).
Regarding your use of FilteredList as well - I've not tried this at all,
but I'll add it to my todo list to investigate today. I imagine there
might be a bug somewhere. Whatever I find will probably make for a good
post at FXExperience, so keep an eye out there too.
Thanks, and if you do run into further issues, please don't hesitate to
file bugs. In general, if TableView isn't sorting then something is
going really wrong!

Hi guys,
I'm working on a business application that makes use of TableView and I'm
working with JDK 8 build b101.
Displaying the data works like a charm. Row sorting for ordinary
ObservableLists is fine too.
Then I've set TableView.items to FilteredList and row sorting was disabled.
replacing TableView.item with SortedList does not allow row sorting as
well. Binding the comparator of SortedList to the TableView.comparator has
no effect either.
// row sorting possible
//final TableView<Integer> tableView = new
TableView<>(FXCollections.observableArrayList(2, 1, 3));
// row sorting not possible (SortedList)
// create a TableView with the sorted list set as the items it will show
// bind the sortedList comparator to the TableView comparator
//SortedList<Integer> sortedList = new
SortedList<>(FXCollections.observableArrayList(2, 1, 3));
//sortedList.comparatorProperty().bind(tableView.comparatorProperty());
//final TableView<Integer> tableView = new TableView<>(sortedList);
// row sorting not possible (FilteredList)
//FilteredList<Integer> filteredList = new
FilteredList<>(FXCollections.observableArrayList(2, 1, 3), (e) -> true);
//final TableView<Integer> tableView = new TableView<>(filteredList );
// Don't forget to define columns!
final TableColumn<Integer, Number> integerColumn = new
TableColumn<>("Integer");
final TableColumn<Integer, String> hexColumn = new TableColumn<>("Integer
Hex");
integerColumn.setCellValueFactory(javaClass -> new
SimpleLongProperty(javaClass.getValue()));
hexColumn.setCellValueFactory(javaClass -> new
SimpleStringProperty(Integer.toHexString(javaClass.getValue())));
tableView.getColumns().addAll(integerColumn, hexColumn);
Any pointers on what I'm doing wrong or where I have to adapt my
expectations.
Is it correct that row sorting in a TableView is only possible for ordinary
ObservableLists?
With Regards
Martin
