Switching scenes in JavaFX dynamically - javafx

Question

I want to switch between 2 different scenes:
Scene 1: ScrollPane where I load different images.
Scene 2: the stage is transparent and there's only 1 button to return to Scene 1.
I´ve been able to do it just having a different fxml for each scene and creating a new scene every time I switch them.
The problem is when I switch from scene 2 to scene 1, all the images loaded in scene 1 aren't there (It´s obvious as I´m creating a new scene rather than "loading" Scene1.
Is there any way to keep the images already loaded when I swith from Scene 2 to Scene 1?
Scene1
public class ControllerImpl implements Initializable, ControlledScreen {
ScreensController myController;
public void initialize(URL url, ResourceBundle rb) {
}
public void setScreenParent(ScreensController screenParent){
myController = screenParent;
}
#FXML
private void goToScreen2(ActionEvent event) throws Exception{
try {
Stage primaryStage = (Stage) hideStage.getScene().getWindow();
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/arrow.fxml"));
Parent root1 = fxmlLoader.load();
primaryStage.setScene(new Scene(root));
}
catch (Exception e) {
e.printStackTrace();
}
}
#FXML
public javafx.scene.control.Button hideStage;
}
Scene2:
public class ControllerArrow implements Initializable{
ScreensController myController;
#Override
public void initialize(URL url, ResourceBundle rb) {
}
public void setScreenParent(ScreensController screenParent){
myController = screenParent;
}
#FXML
public javafx.scene.control.Button showStage;
#FXML
private void goToScreen1(ActionEvent event) throws Exception{
try{
Stage stage = (Stage) showStage.getScene().getWindow();
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/sample.fxml"));
Parent root = fxmlLoader.load();
}
catch (Exception e) {
e.printStackTrace();
}
}
}

You can switch the scene of your stage like:
Stage stage = (Stage) scene.getWindow();
stage.setScene(yourScene);
So when you have an instance of your scene, you can apply it to your stage
