When i add a changeListener to the "listView.getSelectionModel().selectedItemProperty()" - the listView's selectionModel returns false on "isEmpty()" even when there is no item to get.

I think this could be avoided if the order are changed between updating the SelectionModel and invoking the events.
 

Sorry for the many edits.

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {

        try {
            BorderPane root = new BorderPane();
            Scene scene = new Scene(root, 400, 400);

            ObservableList<String> list = FXCollections.observableArrayList("Hello World");
            ListView<String> listView = new ListView<>(list);

            listView.getSelectionModel().selectedItemProperty().addListener((value, s1, s2) -> {
                System.out.println("isEmpty: " + listView.getSelectionModel().isEmpty());
            });
            System.out.println("step 1: selection - expecting selectionmodel.isEmpty to be false");
            listView.getSelectionModel().select(0);

            System.out.println("step 2: removing item - expecting selectionmodel.isEmpty to be true");
            list.remove(0);

            root.setCenter(listView);
            primaryStage.setScene(scene);
            primaryStage.show();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        launch(args);
