JavaFX PropertyValueFactory getCellDataReflectively is not able to retrieve property [duplicate]

This question already has answers here:
Javafx tableview not showing data in all columns
(3 answers)
Why should I avoid using PropertyValueFactory in JavaFX?
(1 answer)
Closed last month.
I'm making a product list and products can have multiple parts attached to it, because sometimes a product is made up of multiple parts. This part of the code is to create a new product. I'm trying to copy a selected row from the list of parts to the table of parts that make up the product. The lists are ObservableList types. The logic seems to make sense, but for some reasons the PropertyValueFactory throws out the same error multiple times whenever I click the button to run the copy.

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

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?>

Output Table view showing no content
PLEASE HELP!!!

Your problem is really simple, you haven't specified the controller in the fxml.
Just add fx:controller="packageName.NewInvoiceController"
at the end of the first line in your fxml file.
So the whole line should be:
<TabPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="720.0" prefWidth="1280.0" tabClosingPolicy="UNAVAILABLE" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="packageName.NewInvoiceController">
Of course, replace packageName with the name of your package.

JavaFX: ListView not displaying in GUI

My problem is that my ListView is not showing anything on the GUI,
I have added a placeholder to test and it does show the placeholder text but other than that I cannot add to the list.
My aim is to have a list of all my clients accounts, I have included the Account class, I want to display all my accounts ID's in the ListView.
For some reason it will not work, I have tried just inputting random data just to see if thats the issue but still not luck.
I have a static Set called allAccounts in my Main.class file.
Any help would be greatly appreciated, I have searched near and far and since I am new to this struggle to understand why this is not working.

You create a new instance of list in Controller, though your listview is initialized in the fxml file. Then you add the items to the new instance, but that one is not added to the scenegraph, hence your original listView remains empty

Edit the values of the TableView from TextField

Hi I am trying in the spirit of the example in http://code.makery.ch/java/javafx-2-tutorial-intro/ to make a similar application where the TableView values can be edited by a series of TextFields instead of a popup form. The reason why I would wannt do it like that is that I am having many fields in a similar application I want to develop and I would like to avoid the user editing them on the TableView
The TableView shows a list of Persons where for each I record name, surname and country. I have tried to create a bidirectionalBinding between the name property of the Person bean and the textProperty() of the TextField but this doesn't work.
I also tried to add to the textProperty a ChangeListener so when it changes to update the ObservableList of propoerties and this also didn't work
Apparently I am doing something wrong and so far I have the following code:
FXDocumentController.java
public class FXMLDocumentController implements Initializable {
private static final Logger logger = Logger.getLogger(FXMLDocumentController.class.getName());
private ObservableList<Person> data;
#FXML
private TableView<Person> tableview;
#FXML
private TableColumn<Person, String> colName;
#FXML
private TableColumn<Person, String> colSurname;
#FXML
private TableColumn<Person, String> colCountry;
#FXML
private TextField name;
#Override
public void initialize(URL url, ResourceBundle rb) {
assert tableview != null : "fx:id=\"tableview\" was not injected: check your FXML file 'UserMaster.fxml'.";
colName.setCellValueFactory(
new PropertyValueFactory<Person,String>("name"));
colSurname.setCellValueFactory(
new PropertyValueFactory<Person,String>("surname"));
colCountry.setCellValueFactory(
new PropertyValueFactory<Person,String>("country"));
DBClass objDbClass = new DBClass();
try{
con = objDbClass.getConnection();
buildData();
tableview.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if (mouseEvent.getButton().equals(MouseButton.PRIMARY)) {
if (mouseEvent.getClickCount() == 1) {
Person p = tableview.getSelectionModel().getSelectedItem();
//name.textProperty().setValue(p.getName());
name.textProperty().bindBidirectional(p.name);
//name.textProperty().bind(p.name);
}
}
}
});
name.textProperty().addListener(new ChangeListener(){
#Override
public void changed(ObservableValue ov, Object t, Object t1) {
System.out.println("Value changed!");
/** Tried also this but this wont work
name.textProperty().setValue((String)t1);
int index = tableview.getSelectionModel().getSelectedIndex();
data.get(index).name.setValue( (String) t1);
tableview.setItems(data);
* */
}
}
);
}
catch(ClassNotFoundException ce){
logger.info(ce.toString());
}
catch(SQLException ce){
logger.info(ce.toString());
}
} //initialize
private void buildData() {
data = FXCollections.observableArrayList();
try{
data.add(new Person("Jon", "Doe", "USA"));
data.add(new Person("Lars", "Andersson", "Sweden"));
tableview.setItems(data);
}
catch(Exception e){
e.printStackTrace();
System.out.println("Error on Building Data");
}
}
}
Person.java
public class Person {
public SimpleStringProperty name = new SimpleStringProperty();
public SimpleStringProperty surname = new SimpleStringProperty();
public SimpleStringProperty country = new SimpleStringProperty();

this.surname.set(surname);
this.country.set(country);
}
public String getName(){
return name.get();
}
public String getSurname(){
return surname.get();
}

}
}

Questions
1) Is it at all possible what I am trying to do?
2) Why isn't this working with bidirectionalBinding
Any help appreciated

I changed your controller class like this
public void initialize(URL url, ResourceBundle rb) {
assert tableview != null : "fx:id=\"tableview\" was not injected: check your FXML file 'UserMaster.fxml'.";
colName.setCellValueFactory(
new PropertyValueFactory<Person,String>("name"));
colSurname.setCellValueFactory(
new PropertyValueFactory<Person,String>("surname"));
colCountry.setCellValueFactory(
new PropertyValueFactory<Person,String>("country"));
buildData();
tableview.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Person>() {
#Override
public void changed(ObservableValue<? extends Person> observable, Person oldValue, Person newValue) {
if (oldValue !=null) name.textProperty().unbindBidirectional(oldValue.nameProperty());
if (newValue !=null) name.textProperty().bindBidirectional(newValue.nameProperty());
}
});
} //initialize
and your person class a bit
public class Person {
private StringProperty name = new SimpleStringProperty();
private StringProperty surname = new SimpleStringProperty();
private StringProperty country = new SimpleStringProperty();
public Person(String name, String surname, String country){
this.name.set(name);
this.surname.set(surname);
this.country.set(country);
}
public StringProperty nameProperty(){return name;}
public StringProperty surnameProperty(){return surname;}
public StringProperty countryProperty(){return country;}
}
Now the TextField can bind to the property in Person
