exception and my application is hanged. Please give me some suggestion.

Answer 1

Does the same binding work for smaller set of data?

Next code works for me. Popup has a 1-2 secs delay before appearing first time although.

public class DoHugeChoiceBox extends Application {
    @Override
    public void start(Stage stage) {
        ObservableList<String> list = FXCollections.<String>observableArrayList();
        for (int i = 0; i < 2000; i++) {
            list.add("item " + i);
        }
        ChoiceBox cb = new ChoiceBox(list);
        cb.getSelectionModel().select(1000);

        HBox g = HBoxBuilder.create().children(cb).build();
        stage.titleProperty().bind(cb.valueProperty());

        stage.setScene(new Scene(g));
        stage.setHeight(100);
        stage.setWidth(200);
        stage.show();
    }

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