こんにちは、私は自分のコードに問題があります。 Tableviewを作成してリスナーを追加しました。リストのアイテムをクリックすると、リストから他のすべてのアイテムが自動的に削除されます。私のコードはまさにそれを行いますが、私はそれを実行したときには、ここで私にエラーJavafx tableView clear（）
を与えるコードです：
public class PgCreatorOverviewController {
@FXML
private TableView<PgAttributes> tableProps;
@FXML
private TableColumn<PgAttributes, String> colonna;
private MainStage mainStage;
private ObservableList<PgAttributes> data =
FXCollections.observableArrayList();
public PgCreatorOverviewController() {
data.add(new PgAttributes("Razza"));
}
@FXML
private void initialize() {
colonna.setCellValueFactory(
cellData -> cellData.getValue().typeProperty()
);
tableProps.setEditable(true);
tableProps.getSelectionModel().selectedItemProperty().addListener(
(observable, oldValue, newValue) -> listener(newValue)
);
}
public void setMainStage(MainStage mainStage) {
this.mainStage = mainStage;
tableProps.setItems(data);
}
public void listener(PgAttributes name) {
if (name.getType().equals("Razza")) {
PgRazzaController razza = mainStage.showPgRazza();
data.clear();
data.add(new PgAttributes("Classe"));
}
if (name.getType().equals("Classe")) {
data.add(new PgAttributes("Caratteristiche"));
}
}
public class PgAttributes {
private final StringProperty type;
public PgAttributes(String name) {
this.type = new SimpleStringProperty(name);
}
public String getType() {
return type.get();
}
public StringProperty typeProperty() {
return type;
}
public void setType(String type) {
this.type.set(type);
}
public boolean equals(PgAttributes uno) {
if (uno.getType().equals(this.getType()))
return true;
return false;
}
}
}
それは動作しますが、コンソールは私にエラーを与えます。ここでスタックトレースは次のとおりです。
