This is my very first time opening an issue so I apologize in advance if I am not completely following the correct protocol. I am almost certain someone will correct me. The bottom line is that I am taking my valuable time to bring this issue to someone's attention.

I am creating a second stage to be used as a modal dialog box. This second stage contains a ChoiceBox and a simple close button (which hides the stage). I display this stage (dialog box), select an item from the choice box, and then click the close button. I then redisplay the stage and simply click the close button which causes the exception "java.lang.IllegalStateException: The window has already been closed at com.sun.glass.ui.Window.checkNotClosed(Unknown Source)". The second stage remains visible. The following code can be used to reproduce the problem

<code>
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ChoiceBox;
import javafx.scene.layout.VBox;
import javafx.stage.Modality;
import javafx.stage.Stage;

public class DialogBoxTest extends Application {
public static void main(String[] args) {
Application.launch(args);
}

@Override
public void start(final Stage primaryStage) throws Exception {
final Button button = new Button("Launch modal dialog");
button.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
final Stage stage = new Stage();
final ChoiceBox<String> startTimeChoiceBox = new ChoiceBox<String>();
startTimeChoiceBox.setPrefWidth(150.0);
startTimeChoiceBox.setMaxWidth(150.0);
startTimeChoiceBox.getItems().addAll("12:00 AM", "1:00 AM",
"2:00 AM", "3:00 AM",
"4:00 AM", "5:00 AM", "6:00 AM",
"7:00 AM","8:00 AM",
"9:00 AM", "10:00 AM", "11:00 AM",
"12:00 PM", "1:00 PM",
"2:00 PM", "3:00 PM", "4:00 PM",
"5:00 PM", "6:00 PM",
"7:00 PM", "8:00 PM", "9:00 PM",
"10:00 PM", "11:00 PM");


Button closeButton = new Button("Close");
closeButton.setOnAction(new EventHandler<ActionEvent>() {

public void handle(ActionEvent event) {
stage.hide();
}
});

VBox vb = new VBox();
vb.getChildren().addAll(startTimeChoiceBox, closeButton);

Scene scene1 = new Scene(vb);
stage.initModality(Modality.APPLICATION_MODAL);
// also tried WINDOW_MODAL
stage.initOwner(primaryStage);
stage.setScene(scene1);
stage.setVisible(true);
}
});
VBox vBox = new VBox();
vBox.getChildren().add(button);
Scene scene = new Scene(vBox, 200, 200);
primaryStage.setScene(scene);
primaryStage.setVisible(true);
}
}
