Moin Leute.
Meines Erachtens müsste meine Tableview funktionieren. Tut sie aber nicht.
Ich mag bestimmt meinen Feher übersehen. Falls jemand mir ihn mal zeigen könnte. Danke schon mal

und die Exception

DataTableModel:
Java:
public class DataTableModel {
private StringProperty vorname;
private StringProperty nachname;
private StringProperty benutzerRolle;
private BooleanProperty schreiben;
private BooleanProperty lesen;
public DataTableModel(String lvorname, String lnachname, String lbenutzerRolle, boolean lschreiben, boolean llesen) {
super();
this.vorname = new SimpleStringProperty(lvorname);
this.nachname = new SimpleStringProperty(lnachname);
}
public DataTableModel() {
}
public String getVorname() {
return vorname.get();
}
public void setVorname(String lvorname) {
vorname.set(lvorname);
}
public String getNachname() {
return nachname.get();
}
public void setNachname(String lnachname) {
nachname.set(lnachname);
}
Controller:
Java:
public class MainWindowController implements Initializable {
@FXML
private TableView<DataTableModel> tvView;
@FXML
private TableColumn<DataTableModel, String> colVorname;
@FXML
private TableColumn<DataTableModel, String> colNachname;
@Override
public void initialize(URL location, ResourceBundle resources) {
ObservableList<DataTableModel> liste = FXCollections.observableArrayList();
DataTableModel datamodel = new DataTableModel();
cbBenutzerrolle.setItems(cbList);
colVorname.setCellValueFactory(new PropertyValueFactory<DataTableModel, String>("vorname"));
colVorname.setCellValueFactory(new PropertyValueFactory<DataTableModel, String>("nachname"));
liste.add(getDataTableModel(datamodel));
tvView.setItems(liste);
}
und die Exception
