NullPointerException при работе с TableView

Не могу понять в чем проблема, вроде все делаю по oracle tutorials. Но что-то не все верно получается.

Main.java

package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class Main extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent parentRoot = FXMLLoader.load(getClass().getResource("../fxml/parentRoot.fxml"));
        Parent centerRoot = FXMLLoader.load(getClass().getResource("../fxml/centerRoot.fxml"));
        BorderPane borderPane = (BorderPane) parentRoot;
        AnchorPane anchorPane = (AnchorPane) centerRoot;
        borderPane.setCenter(anchorPane);
        Scene loadScene = new Scene(borderPane);
        primaryStage.setTitle("Service");
        primaryStage.setScene(loadScene);
        primaryStage.show();
    }
    public static void main(String[] args) {
        launch(args);
    }
}

primaryController.java

package controllers;
import classes.Person;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.scene.control.Label;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
public class primaryController {
    @FXML
    private TableColumn<Person, String> firstNameColumn;
    @FXML
    private TableColumn<Person, String> lastNameColumn;
    @FXML
    private Label firstNameLabel;
    @FXML
    private Label lastNameLabel;
    @FXML
    private TableView<Person> personTable;
    private ObservableList<Person> personData = FXCollections.observableArrayList();
    @FXML
    private void initialize() {
        personData.add(new Person("Denys", "Savenko"));
        personData.add(new Person("Evgeniy", "Revutskiu"));
        firstNameColumn.setCellValueFactory(new PropertyValueFactory<>("firstName"));
        lastNameColumn.setCellValueFactory(new PropertyValueFactory<>("lastName"));
        personTable.setItems(personData);
    }
}

Person.java

package classes;
import javafx.beans.property.SimpleStringProperty;
public class Person {
    private SimpleStringProperty firstName;
    private SimpleStringProperty lastName;
    public Person(String firstName, String lastName) {
        this.firstName = new SimpleStringProperty(firstName);
        this.lastName  = new SimpleStringProperty(lastName);
    }
    public void setFirstName(String firstName) {
        this.firstName.set(firstName);
    }
    public String getFirstName() {
        return this.firstName.get();
    }
    public SimpleStringProperty firstNameProperty() {
        return firstName;
    }
    public void setLastName(String lastName) {
        this.lastName = new SimpleStringProperty(lastName);
    }
    public String getLastName() {
        return this.lastName.get();
    }
    public SimpleStringProperty lastNameProperty() {
        return lastName;
    }
}

Файлы parentRoot.fxml и centerRoot.fxml не привожу (думаю там ничего интересного нету). Stack trace, который я получаю в итоге:
