So I was getting started with javaFxml, and I was creating a simple notes program. I wasn't able to Make a new window for adding items to the list of existing ones, so I tried again on a specific new program, but nothing worked. This is the code:

Main class `

package com.scratch.test2;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;

import java.io.IOException;

public class Main extends Application {
    @Override
    public void start(Stage stage) throws IOException {
        FXMLLoader fxmlLoader = new FXMLLoader(Main.class.getResource("mainfx.fxml"));
        Scene scene = new Scene(fxmlLoader.load(), 320, 240);
        stage.setTitle("Scratch file writer - test");
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }
}

`Main FXML file

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.control.MenuBar?>
<?import javafx.scene.control.Menu?>
<?import javafx.scene.control.MenuItem?>
<BorderPane xmlns:fx="http://javafx.com/fxml" fx:id="mainBorderPane"
            fx:controller="com.scratch.test2.Controller">

    <center>
        <MenuBar>
            <Menu text="File">
                <items>
                    <MenuItem  text="New" fx:id="newItem" onAction="#createNewItem"/>
                </items>
            </Menu>
        </MenuBar>
    </center>

</BorderPane>

**Main Controller** 

package com.scratch.test2;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.ButtonType;
import javafx.scene.control.Dialog;
import javafx.scene.layout.BorderPane;
import java.io.IOException;

public class Controller {
    @FXML
    private BorderPane mainBorderPane;


    @FXML
    public void createNewItem() {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("new-item.fxml"));
        Dialog<ButtonType> dialog = new Dialog();
        dialog.initOwner(mainBorderPane.getScene().getWindow());

        try{
            dialog.getDialogPane().setContent(fxmlLoader.load());
        }catch (IOException e){
            e.printStackTrace();
        }
    }
}

New FXML file:`

<?xml version="1.0" encoding="UTF-8"?>
        <?import javafx.scene.control.*?>
        <?import javafx.scene.layout.*?>


<DialogPane      xmlns:fx="http://javafx.com/fxml"
      fx:controller="com.scratch.test2.ControllerTwo">

        <headerText>
                please enter whatever you like
        </headerText>

        <content>
                <GridPane>
                        <Label text="enter here"/>
                        <TextField fx:id="textF" />
                </GridPane>
        </content>
</DialogPane>

new controller:

package com.scratch.test2;

import javafx.fxml.FXML;
import javafx.scene.control.TextField;

public class ControllerTwo {

    @FXML
    private TextField textF;

    public void processResults(){

        //I will use this later

        String text = textF.getText();
        System.out.println(text);
    }
}

and here's the error coming up:

`

after pressing on "File", then "New", a new window should open asking to write your note, but as the new button is pressed an error occurs.
