滾動時JavaFX TreeTableView行已消失

Question

我一直在JDK 8試驗TreeTableView 。 在我的程序啟動並運行后，我注意到一個問題，當我滾動時，行將被消隱。 我已嘗試過重置單元格的可見性，更新時的所有內容，希望在更新時重繪，甚至重置列的可見性。 這是一個我編寫的測試applet，顯示當你滾動樹表視圖時，行被消隱了，但對於表視圖，情況並非如此。

public class TableViewTest extends Application{

private TreeTableView treeTable = new TreeTableView();
private TableView regularTable = new TableView();

 public static void main(String[] args) {
        launch(args);
    }

@Override
public void start(Stage stage) throws Exception {

    final ObservableList<Person> data = FXCollections.observableArrayList(
            new Person("Jacob", "Smith", "jacob.smith@example.com"),
            new Person("Isabella", "Johnson", "isabella.johnson@example.com"),
            new Person("Ethan", "Williams", "ethan.williams@example.com"),
            new Person("Emma", "Jones", "emma.jones@example.com"),
            new Person("Michael", "Brown", "michael.brown@example.com"),
            new Person("Jacob", "Smith", "jacob.smith@example.com"),
            new Person("Isabella", "Johnson", "isabella.johnson@example.com"),
            new Person("Ethan", "Williams", "ethan.williams@example.com"),
            new Person("Emma", "Jones", "emma.jones@example.com"),

        );

    treeTable.setEditable(true);

    TreeTableColumn firstNameCol = new TreeTableColumn("First Name");

    lastNameCol.setCellValueFactory(new TreeItemPropertyValueFactory<Person,String>("lastName"));

    TreeItem<Person> root = new TreeItem<Person>(new Person("TEST", "TEST", "TEST"));

    treeTable.setRoot(root);
    treeTable.setShowRoot(true);
    root.setExpanded(true);

    for (Person person : data){
        TreeItem<Person> p = new TreeItem<Person>(person);
        root.getChildren().add(p);
    }

    stage.show();


}

有沒有人知道修復/解決方案，或者這是TreeTableView的已知錯誤？

編輯：我剛試過這個例子

https://wikis.oracle.com/display/OpenJDK/TreeTableView+API+Examples

我仍然得到相同的行丟失/被刪除的問題。

感謝@Alexander Kirov的解決方案。 升級到build 104解決了這個問題。
