JavaFX 2 dynamic dot loading - javafx-2

Question

I wanna create some loading dots like this:
At 0 second the text on the screen is: Loading.
At 1 second the text on the screen is: Loading..
At 2 second the text on the screen is: Loading...
At 3 second the text on the screen is: Loading.
At 4 second the text on the screen is: Loading..
At 5 second the text on the screen is: Loading...
and so forth until I close the Stage.
What is the best / easiest way to make that in JavaFX? I've been looking into animations/preloaders in JavaFX but that seems to complex when trying to achieve this.
I've been trying to create a loop between these three Text:
Text dot = new Text("Loading.");
Text dotdot = new Text("Loading..");
Text dotdotdot = new Text("Loading...");
but the screen stays static...
How can I make this work correctly in JavaFX? Thanks.

This question is similar to: javafx animation looping.
Here is a solution using the JavaFX animation framework - it seems pretty straight forward to me and not too complex.
import javafx.animation.*;
import javafx.application.Application;
import javafx.event.*;
import javafx.scene.*;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javafx.util.Duration;
/** Simple Loading Text Animation. */
public class DotLoader extends Application {
#Override public void start(final Stage stage) throws Exception {
final Label status = new Label("Loading");
final Timeline timeline = new Timeline(
new KeyFrame(Duration.ZERO, new EventHandler() {
#Override public void handle(Event event) {
String statusText = status.getText();
status.setText(
("Loading . . .".equals(statusText))
? "Loading ."
: statusText + " ."
);
}
}),
new KeyFrame(Duration.millis(1000))
);
timeline.setCycleCount(Timeline.INDEFINITE);
VBox layout = new VBox();
layout.getChildren().addAll(status);
layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10;");
stage.setScene(new Scene(layout, 50, 35));
stage.show();
timeline.play();
}
public static void main(String[] args) throws Exception { launch(args); }
}

Answer 2

Have you considered to use a Progress Indicator or a Progress Bar? I think they can be a good solution to show an animation and avoid problems.
I've been able to do it in JavaFX, not with Animations, but using the concurrency classes from JavaFX.
I let you the code here in a gist. I think it isn't very intuitive, because I prefer a progress indicator. And maybe it isn't the best solution, but maybe this will help you.
