FXML Load exception when inserting data of own class into tableview

I have a problem again.
I am trying to understand FXML and I am currently using the "Mastering FXML" guide of oracle "creating an address book with FXML".
I am pretty near at the end of the guide but i am not able to fix a problem I have since yesterday.
I want to write a Maintenance Program for my father but I am always getting the statement:javafx.fxml.LoadException: Maintenance is not a valid type.
there are 3 classes that are important for this problem I guess. That would be my "mainLayout.fxml", "FXMLDocumentController.java" and "Maintenance.java"
So I am just posting them in this order

insertwindow.fxml is existing and worked great so far so I won't post it to shorten my post same for main.java and my 4 property files.
Hope someone can tell me what I am doing wrong again.
Thanks for help!

For custom FXML type you should add an import statement:
<?import Maintenance?>
In general it is bad practice to use default packages. Put the Maintenance.java into some package and import it as:
<?import yourPackageName.Maintenance?>

How to simulate a queue and a stack JavaFX with pause, threads(task, service)

I been searching in YouTube, Stack-Overflow and fxexperience, even oracle documentation but I still don't get it.
There's not similar example :(
The problem is how to do a stack and queue simulator.
Generate 10 random numbers. Done.
Show the numbers in a table. Done.
Use the 10 random numbers to simulate a stack and a queue. I don't now how to comunicate the service with the TextField.
Pause the simulation. or Stop.
-The program needs a pause method. I don't know how to pause a thead. Perhaps with wait() and notify(). I don't know.
I have used label.textProperty.bind(service.progressProperty()). this works but when i try to bind a variable instead
the method updateProgress(i,n) throws a exception.
Maybe I need to use 2 Tasks.

There's a lot of code in the question, and I don't think you need it all to address the concepts you're actually asking about. So I'll just give a high-level answer here. If you want to edit your question to something much simpler that addresses the actual issue, then I can make this specific to that example.
I would probably try to do this without threads at all, but using the animation API. For example, you could use a Timeline, with the following basic outline:
public class Controller {
// #FXML-annotated UI elements...
// Other state....
private Timeline timeline ;
#FXML
public void initialize() {
timeline = new Timeline(new KeyFrame(Duration.seconds(100)), e -> {
if (moreStepsToDo()) {
doNextStep();
} else {
stopSimulation();
}
});
timeline.setCycleCount(Animation.INDEFINITE);
}
private boolean moreStepsToDo() {
// return true if there are more steps in the simulation,
// false otherwise
}
private void doNextStep() {
// do next step in the simulation
}
#FXML
private void stopSimulation() {

The nice thing about this solution is that everything is single-threaded: the event handler for the key frame is executed on the FX Application Thread, which is the same thread that executes the event handlers. This means there is no need to worry about synchronizing data across threads. The predefined methods in the animation API pause(), play(), and stop() provide exactly the functionality you're looking for; you just have to update the application state appropriately.
Here's a simple complete example that uses this approach (it just moves a bunch of rectangles, one at a time, from one vbox to another).
import javafx.animation.Animation;
import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.geometry.Pos;
import javafx.scene.Node;

import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;

import javafx.util.Duration;
public class SimplePausableAnimation extends Application {
private VBox left;
private VBox right;

#Override

left.setMinWidth(200);
right = new VBox(10);
right.setMinWidth(200);
HBox hbox = new HBox(10, left, right);
pausePlay = new Button();
Button reset = new Button("Reset");
reset.setOnAction(e -> reset());
reset();
BorderPane root = new BorderPane(hbox);
HBox buttons = new HBox(5, pausePlay, reset);
buttons.setAlignment(Pos.CENTER);
root.setBottom(buttons);
Scene scene = new Scene(root, 600, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
private void reset() {
if (timeline != null) {
timeline.stop();
}
left.getChildren().clear();
right.getChildren().clear();
for (int i = 0; i < 5; i++) {
left.getChildren().add(new Rectangle(100, 100, Color.CORNFLOWERBLUE));
}
timeline = new Timeline(new KeyFrame(Duration.seconds(1), e -> {
if (moreStepsToDo()) {
doNextStep();
} else {
timeline.stop();
}
}));
timeline.setCycleCount(Animation.INDEFINITE);
pausePlay.disableProperty().bind(Bindings.createBooleanBinding(() -> {
if (left.getChildren().isEmpty()) {
return true;
}
return false;
}, left.getChildren()));
pausePlay.textProperty().bind(Bindings.createStringBinding(() -> {
if (timeline.getStatus() == Animation.Status.RUNNING) {
return "Pause";
}
return "Play";
}, timeline.statusProperty()));
pausePlay.setOnAction(e -> {
if (timeline.getStatus() == Animation.Status.RUNNING) {
timeline.pause();
} else {
timeline.play();
}
});
}
private boolean moreStepsToDo() {
return !left.getChildren().isEmpty();
}
private void doNextStep() {
int n = left.getChildren().size();
Node node = left.getChildren().remove(n - 1);
right.getChildren().add(node);
}
public static void main(String[] args) {
launch(args);
}
}
If you do want to do this with threads, one approach to pausing a thread is to use a Semaphore with a single permit. This generally looks something like this:
Semaphore pauser = new Semaphore(1);
Thread simulationThread = new Thread(() -> {
try {
while (! Thread.currentThread().isInterrupted()) {
pauser.acquire();
// do simulation step
pauser.release();
Thread.sleep(100);
}
} catch (InterruptedException exc) {
// ignore and exit thread...
}
});
(Obviously the same idiom will work in your Task, which is executed on a background thread.)
Then calling pauser.acquire(); from the controller will pause the simulation (because the simulation thread will not be able to acquire the permit), and calling pauser.release() while it is paused will let it run again.

Populating TableView in JavaFX From Data in SQLite

I am trying to populate a TableView from data in SQLite database but I am experiencing a very weird scenario that I cannot understand what is causing it.
The tableview only populates two columns and does not populate the rest. The Tablecolumns with 'NO' and 'Date Created' do not get populated when the TableView is finally displayed.
This code however displays data from SQLite database in 'Title' and 'Description' TableView columns.
Please someone with a hawk eye help me identify where I am going wrong on this code. I have spent the better part of the day trying to figure out where I am going wrong but I do not seem to figure out what it is that I am not doing it right. I will gladly appreciate any help on this.
Here is my code for

There is a mistake regarding your property naming.
Your function for getDateCreated and IdNO don't correlate with
the naming convention.
Replace
public SimpleStringProperty datecreated = new SimpleStringProperty();
public SimpleStringProperty idno = new SimpleStringProperty();
with
public SimpleStringProperty dateCreated = new SimpleStringProperty();
public SimpleStringProperty idNO = new SimpleStringProperty();
And have a look at the naming conventions for properties

Empty window showing up when running javaFX application, using both graphic view and scenebuilder

I am currently writing a poker game as an assignment for my finals. I have to use a combined view: a class with actual code and the Scenebuilder. I did everything i learned and the model is working just fine. I'm new to this so it must be an easy fix! The professors want us to get familiar with Scenebuilder but they didn't give much of an explanation.
As you can see i use a class called pokerView in which I load in every single image of the cards. In the beginning I use a strange forloop to automatically generate the names of the images, I printed it out and the url is okay!
I also use the scenebuilder. It has it's own controller/view class that is the FXMLpokerController
And to combine those two, I used a "super" view.
Funny thing is that java does not give me any error!
I really really need an answer. If the window show up empty I cannot show the app.
So the terminal gives me the following lines when using the printstacktrace
javafx.fxml.LoadException:

You have named your AnchorPane "deal" in the FXML and your Button as "deal" in the controller. During initialization, the mapping is done by name. Since these objects are not the same type, you are getting a class exception.
If the button is really deal, move the id from the AnchorPane to the button in the FXML. Based on this:
deal.setOnAction(this::deal);
I assume the button should be called deal.
Change this line
<AnchorPane id="AnchorPane" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
and this line
<Button fx:id="deal" layoutX="249.0" layoutY="495.0" mnemonicParsing="false" text="deal" />

Your AnchorPane has the fx:id "deal":
<AnchorPane id="AnchorPane" fx:id="deal" prefHeight="605.0" prefWidth="556.0" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="poker.FXMLpokerController">
In your controller class FXMLpokerController you define "deal" as a button:
#FXML
private Button deal;
The FXML injection cannot initialize a Button as an AnchorPane. Move the fx:id to the correct button and give your AnchorPane a different fx:id.

Adapting Oracle's Address book tutorial to include cell editing

I'm a novice and would very like a to know how to make a column cell editable when using FXML.
Specifically, I have been following the two working examples provided by Oracle. The first one (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm) allows editing.
The second example ( http://docs.oracle.com/javafx/2/fxml_get_started/fxml_tutorial_intermediate.htm ) suggests at the bottom of the tutorial that it can be edited but doesn't show how this is achieved.
I have read the answers to the related questions but they are beyond my current level ofknowledge.
Can anyone show me how it can be done in as simpler way as possible please?
To save you looking up the tutorial these are the files which I've copied directly from Oracle:
Thanks in advance.
First is FXMLTableView.java
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package fxmltableview;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
public class FXMLTableView extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("FXML TableView Example");
Pane myPane = (Pane)FXMLLoader.load(getClass().getResource
("fxml_tableview.fxml"));
Scene myScene = new Scene(myPane);
primaryStage.setScene(myScene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
The second one is the controller:
package fxmltableview;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.TableView;
import javafx.scene.control.TextField;
public class FXMLTableViewController {
#FXML private TableView<Person> tableView;
#FXML private TextField firstNameField;
#FXML private TextField lastNameField;
#FXML private TextField emailField;
#FXML
protected void addPerson(ActionEvent event) {
ObservableList<Person> data = tableView.getItems();
data.add(new Person(firstNameField.getText(),
lastNameField.getText(),
emailField.getText()
));
firstNameField.setText("");
lastNameField.setText("");
emailField.setText("");
}
}
The third file is FormattedTableCellFactory.java
package fxmltableview;
import java.text.Format;
import javafx.geometry.Pos;
import javafx.scene.Node;
import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.text.TextAlignment;
import javafx.util.Callback;
public class FormattedTableCellFactory<S, T>
implements Callback<TableColumn<S, T>, TableCell<S, T>> {
private TextAlignment alignment;
private Format format;
public TextAlignment getAlignment() {
return alignment;
}
public void setAlignment(TextAlignment alignment) {
this.alignment = alignment;
}
public Format getFormat() {
return format;
}
public void setFormat(Format format) {
this.format = format;
}
#Override
#SuppressWarnings("unchecked")
public TableCell<S, T> call(TableColumn<S, T> p) {
TableCell<S, T> cell = new TableCell<S, T>() {
#Override
public void updateItem(Object item, boolean empty) {
if (item == getItem()) {
return;
}
super.updateItem((T) item, empty);
if (item == null) {
super.setText(null);
super.setGraphic(null);
} else if (format != null) {
super.setText(format.format(item));
} else if (item instanceof Node) {
super.setText(null);
super.setGraphic((Node) item);
} else {
super.setText(item.toString());
super.setGraphic(null);
}
}
};
cell.setTextAlignment(alignment);
switch (alignment) {
case CENTER:
cell.setAlignment(Pos.CENTER);
break;
case RIGHT:
cell.setAlignment(Pos.CENTER_RIGHT);
break;
default:
cell.setAlignment(Pos.CENTER_LEFT);
break;
}
return cell;
}
}
The fourth file is the Person class:
package fxmltableview;
import javafx.beans.property.SimpleStringProperty;
public class Person {
private final SimpleStringProperty firstName = new SimpleStringProperty("");
private final SimpleStringProperty lastName = new SimpleStringProperty("");
private final SimpleStringProperty email = new SimpleStringProperty("");
public Person() {
this("", "", "");
}
public Person(String firstName, String lastName, String email) {
setFirstName(firstName);
setLastName(lastName);
setEmail(email);
}
public String getFirstName() {
return firstName.get();
}
public void setFirstName(String fName) {
firstName.set(fName);
}
public String getLastName() {
return lastName.get();
}
public void setLastName(String fName) {
lastName.set(fName);
}
public String getEmail() {
return email.get();
}
public void setEmail(String fName) {
email.set(fName);
}
}
and the last file is the .fxml file:
