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!

Exception running application Main

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?>

Making changes in another JavaFX Controller on the same Scene

This is what my view looks like:
Explanation
The entire window itself runs on one controller, called the CartWindowController, and the product list itself is a JavaFX Custom Control called CartItemComponent, which has it's own controller. Each item in the list, therefore has it's own instance of the controller as I programmatically make an instance and populate a VBox.
Problem
I cannot figure out how to notify the CartWindowController when the user clicks on the "X" button, which is handled by the "CartItemComponent" Controller. I would highly appreciate it if anyone could give me a heads up on how to tackle this problem.
Here's what my FXML looks like for the entire Window:

Something you could try is to pass the CartWindowController into the CartItemComponent constructor, then when you need to notify the CartWindowController, you call a method or set a flag or trigger an event, your choice! All you would need to do is add a parameter of type CartWindowController to you CartItemComponent and just save the reference.

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.

tableview not showing data from database

I am unable to populate my tableview. I believe the problem is in the controller, in the way my data is being sent to the FXML file, because a system out print (see below) shows exactly what I have in my database.
Please let me know where I did a mistake. I went over all tutorials that exist on that, but nothing fits my problem.

You're creating a new TableView and setting its items, instead of setting the items on the table that the FXML file defined. Remove the
tableView = new TableView<Person>();
from the controller.
To get the #FXML-annotated fields in the controller to be populated with the appropriate elements from the FXML file, you need to add fx:id attributes to those elements:
<TableView fx:id="tableview" ... >
<columns>
<TableColumn fx:id="firstNameColumn" ... />

Thank you in advance. I hope somebody can help me. (sorry for my bad english)

Your controller is declaring chTaal as a ChoiceBox but your FXML is declaring it as a ComboBox. The FXMLLoader can't coerce a conversion between those types so it doesn't set chTaal to anything, leaving it as null. Make the types match in the two files and see if that corrects your issue.
