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

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.

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?>
I have a program that is basically a task manager, it takes information from SQLite Database. it has 5 info fields (UID, Date, CreatedBy, Category, Task). In order to populate the table view I use class Model Table.
Controller
#FXML public TableView<ModelTable> taskManagerView;
#FXML public TableColumn<ModelTable, String> col_UID;
#FXML public TableColumn<ModelTable, String> col_Date;
#FXML public TableColumn<ModelTable, String> col_CreatedBy;
#FXML public TableColumn<ModelTable, String> col_Category;
#FXML public TableColumn<ModelTable, String> col_Task;
ObservableList<ModelTable> oblist = FXCollections.observableArrayList();
public FilteredList<ModelTable> filteredOblist = new FilteredList<>(oblist, s -> true);
try{
Connection conn =
DriverManager.getConnection("jdbc:sqlite://Location\\");
Statement statement = conn.createStatement();
ResultSet rs =statement.executeQuery("SELECT * FROM TaskManagerData");
while (rs.next()){
oblist.add(new ModelTable(rs.getString("UID"), rs.getString("Date"), rs.getString("CreatedBy"), rs.getString("Category"),rs.getString("Task")));
}
}catch (SQLException e){
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("DB Error");
alert.setHeaderText("DB Connection Failed");
alert.setContentText(e.getMessage());
alert.showAndWait();
}
col_UID.setCellValueFactory(new PropertyValueFactory<>("UID"));
col_Date.setCellValueFactory(new PropertyValueFactory<>("Date"));
col_CreatedBy.setCellValueFactory(new PropertyValueFactory<>("CreatedBy"));
col_Category.setCellValueFactory(new PropertyValueFactory<>("Category"));
col_Task.setCellValueFactory(new PropertyValueFactory<>("Task"));
taskManagerView.setItems(filteredOblist);
ModelTable gettingTask =taskManagerView.getSelectionModel().getSelectedItem();
detailedTask.setText(gettingTask.getTask());
Model Table:
public class ModelTable {
String UID, Date, CreatedBy, Category, Task;
package Controllers;
public class ModelTable {

My question is how can i have it so my program when i select for example UID 7 (when the program is running) from the table view the information from "Task" appears in a text area in the program. Currently
Hopefully this was understandable.
Thank you.
The selection happens after the scene is displayed. If retrieved before (e.g. in the initialize method), the selectedItem property is null. Add a listener to the property to do the updates instead:
#FXML
private void initialize() {
taskManagerView.getSelectionModel().selectedItemProperty().addListener((o, oldValue, newValue) -> {
if (newValue == null) {
textArea.setText("");
// TODO: clear other controls
} else {
textArea.setText(newValue.getTask());
// TODO: set values to other controls
}
});
}

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.
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.

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
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;

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);

}
}
);
}

}

logger.info(ce.toString());
}
} //initialize

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();
public Person(String name, String surname, String country){
this.name.set(name);
this.surname.set(surname);
this.country.set(country);
}
public String getName(){
return name.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;}
