JavaFX - Adding Data to a TableView from a Different Scene

I am attempting to capture the TextField and Control Field values entered from the addItems.java class. Then display that data on the TableView generated on the shoppingCartController.java class. I do not get an error message when I hit add on the addItems.java file, but when I go back to the main shoppingCartController scene the entered data is not there.
Below is what is called when the 'Add' button is selected:
public void handleitemAdd(ActionEvent event) throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(getClass().getResource("additems.fxml"));
Parent addItem_page = loader.load();
ObservableList<Products> list = FXCollections.observableArrayList();
list.add(new Products(productPriority.toString(),
productName.getText(),
Double.parseDouble(productPrice.getText()),
Integer.parseInt(productQty.getText())));
table.getItems().add(list);
System.out.println("Displaying information to consoles: Ensuring the addItem method worked as expected.");
}
Any assistance in reviewing this issue would be appreciated.

Edit:
I appreciate the assistance, I am still learning Java and had a follow-up question.
I updated the addItems.java to include:
public void handleitemAdd(ActionEvent event) throws IOException {
products.add(new Products(productPriority.toString(),
productName.getText(),
Double.parseDouble(productPrice.getText()),
Integer.parseInt(productQty.getText())));
System.out.println("Displaying information to consoles: Ensuring the addItem method worked as expected.");
}
As well as the shoppingCartController to include:
public void setTableItems(ObservableList<Products> products) throws IOException {
FXMLLoader loader = new FXMLLoader(getClass().getResource("shoppingcart.fxml"));
Scene shoppingCart_scene = new Scene(loader.load());
shoppingCartController controller = loader.getController();
controller.setTableItems(products);
}
But the value is still not carried over, I also ensured that the parameters are being captured (confirmed with debug mode).

As #Kleopatra said in the comment static access can be tricky sometimes so be careful and stick to java common naming conventions your code is hard to trace
you can pass the item back to the ShoppingCart when returning to it by setting the list via the controller
FXMLLoader loader = new FXMLLoader(getClass().getResource("shoppingcart.fxml"));
Scene shoppingCart_scene = new Scene(loader.load());
shoppingCartController controller = loader.getController();
controller.setProducts(list);
and in setProduct() function you can update the table
OR
You can create your ObservableList outside the static function but I don't recommend so and I suggest you search about passing data between controllers in javafx see the link below

JavaFX control spinner dont works

Hi I'd like add to control "Spinner" integers between 1 to 24. I write my function and i added to fxml file but display exception (JavaFX 11).

Init

As i have same problem, So here is the solution i found
Just need to rearrange the code a little bit like this..
#Override

SpinnerValueFactory<Integer> spinner =new SpinnerValueFactory.IntegerSpinnerValueFactory(1,24,7);
fromHourSpinner.setValueFactory(spinner);
toHourSpinner.setValueFactory(spinner);

});
}
}
when I am trying to add the listener at the end it is not working. I can't get any options for textfield when I do e_key_tb. and ctrl+space where it is supposed to give a drop down box with a bunch of suggestions ... I used the scene-builder to provide id and copied the controller skeliton from the scene-builder ... later when I'm trying to use the textfield it made me create getters and setters for all the textfields can you explain me y it s happening and I never used listeners before.

Here is a short demonstration of adding a listener to a TextField. This can also serve as an example for mcve for the issue:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.control.TextField?>
<HBox prefHeight="75.0" prefWidth="150.0" alignment="CENTER"
xmlns="http://javafx.com/javafx/8.0.121" xmlns:fx="http://javafx.com/fxml/1" fx:controller="tests.Controler">
<children>
<TextField fx:id="msg_tb" prefHeight="25.0" prefWidth="100.0" style="-fx-background-radius: 10;" />
</children>
</HBox>
The controller :
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TextField;
public class Controler implements Initializable {
#FXML
private TextField msg_tb;
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
msg_tb.textProperty().addListener((obs, oldText, newText) -> {
System.out.println("Text changed from "+ oldText +" to "+newText);
});
}
}
Test it:
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
public class FxmlMain extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
Pane root = FXMLLoader.load(getClass().getResource("xml/FxmlMain.fxml"));
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) { launch(args);}
}

JavaFX MVC what should be handled by the controller and what by the main application?

I've recently made a java swing application to play oxo and I'm trying to make it again in javaFX using the MVC design pattern. I'm strugling as to what should be handled in which part of my application.
How it looked in swing (see picture link)
The design in javaFX using fxml (see picture link)
The folder structure is (see picture link)
To make this abstract question more concrete: I handle the click in my controller but what do I do with it then? Do I handle my game logic there? Or should I just determine the source and send it up to my main app to do the rest?

JAVAFX javafx.fxml.LoadException simple login page

Getting LoadExeption evertime i try to run this code.
the code ran fine the first time but after that i just keep getting this error.
Its just a simple login page with not much coding what so ever.
Main class below
package application;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
try {
Parent root=FXMLLoader.load(getClass().getResource("/application/Login.fxml"));
Scene scene = new Scene(root,400,400);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args); // tried changing this to string[0] didnt work
}
}
Main controller class below i wanted to add more sql stuff to this but i keep getting the same error.
In this i am just trying to change
package application;
import java.awt.Label;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import javafx.fxml.FXML;
public class MainController {
#FXML
private Label LblStatus;
#FXML
private TextField TxtUsername;
#FXML
private TextField TxtPassword;
public void Login(ActionEvent event)
{
LblStatus.setText("Login sucsess");
}
}
login page
All of this was created using scene builder and youtube.
so i basically have no idea why i am getting this error.

You have the wrong imports in your controller. Replace
import java.awt.Label;
with
import javafx.scene.control.Label ;
etc...
