FULL PRODUCT VERSION :
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Windows 64bit ver 7
A DESCRIPTION OF THE PROBLEM :
When I run the following program
import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.Pane;
import javafx.scene.layout.StackPane;
import javafx.scene.shape.Ellipse;
import javafx.stage.Stage;
public class Test1 extends Application {
public static void main(String[] args) throws Exception {
launch(args);
}
@Override
public void start(Stage stage) throws Exception {
Pane topPane = new Pane();
Scene scene = new Scene(topPane, 600, 400);
StackPane sp = new StackPane();
Label l1 = new Label("1 2");
Ellipse e1 = new Ellipse(100, 50);
e1.setOpacity(0.5);
sp.getChildren().addAll(l1, e1);
e1.radiusXProperty().bind(l1.widthProperty());
e1.radiusYProperty().bind(l1.heightProperty());
topPane.getChildren().add(sp);
sp.relocate(200, 100);
sp.setStyle("-fx-border-color: RED;");
Platform.runLater(() -> {
//l1.setText("123");
//l1.setText("1 2");
});
stage.setScene(scene);
stage.show();
}
}
I get a red box surrounding the text label only, but when I uncomment the two lines inside the Platform.runLater() block above, I get a red box surrounding the outer ellipse, which is what I want. So it seems to me the layout bounds of the stack pane is not set correctly from the model description, since the bounds are determined only from the label control. But when I force an invalidation in Platform.runLater() the layout bounds are where they should be.
Why is this happening and how do I prevent it? I would like to be able to just specify my model/graph and then it should render correctly on the first show, or?

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the program in the description and it will happen.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect to see a a red box border surrounding the outer ellipse, as specified in the model.
ACTUAL -
I see a red box surrounding the label. But if I uncomment the 2 comment lines in the code, I get the expected behaviour.
REPRODUCIBILITY :
This bug can be reproduced always.
