I have a strange behavior while closing an APPLICATION_MODAL window which have an owner (parent) window.
I was expected that its parent will remain on top of all other windows but instead others are brought to top without any Event.


Here is the sample code I used to reproduce this behavior, close the "Child" window and look how "free" windows behave.

package mypkg;

import javafx.application.Application;
import javafx.event.Event;
import javafx.event.EventHandler;
import javafx.stage.Modality;
import javafx.stage.Stage;
import javafx.stage.StageBuilder;

public class WinHierarchy extends Application {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
launch(WinHierarchy.class, args);

}

@Override
public void start(Stage primaryStage) throws Exception {

Stage stage = StageBuilder.create().title("Child").build();
primaryStage.setTitle("Parent");
stage.initOwner(primaryStage);
stage.initModality(Modality.APPLICATION_MODAL);

primaryStage.show();

// USED TO TRACK EVENTS
applyEventFilter(stage);
applyEventFilter(primaryStage);

buildFreeWindow(5);
stage.showAndWait();
}

private void buildFreeWindow(int count) {
for (int i = 0; i < count; i++) {

Stage free = StageBuilder.create().title("free").build();
applyEventFilter(free);
free.show();
}
}

private void applyEventFilter(Stage stage) {
stage.addEventFilter(Event.ANY, new EventHandler<Event>() {

@Override
public void handle(Event event) {
System.out.println(event);
}

});
}

}
