Exception 选择项时，Tableview引发索引越界异常

我有一个JavaFXTableView。当我点击一行时，我收到一个异常。异常不提供指向我的代码的指针，以指示我的错误可能在哪里

这是selectedItem属性侦听器：

orderTable.getSelectionModel().selectedItemProperty().addListener(
        (observable, oldValue, newValue) -> {
            if (newValue != null) orderSelected();
        });

侦听器完成后会发生异常。我一直无法理解为什么仅仅通过从表中选择一个有效的、可见的项来生成索引越界异常

例外情况是：

我在尝试提供一个“最小的、完整的和可验证的”示例时发现了这个问题

名为orderSelected（）的表选择侦听器：

---

clear（）之后，任何更新表的操作（包括屏幕刷新）都会引发异常。

您能创建一个复制相同错误的操作吗？您在应用程序中执行任何多线程处理吗？

orderSelected（）

做什么？如果它修改了

项

或选择，这可能会导致错误，因为JavaFX希望在侦听器执行期间不会修改属性。@James\u D我希望能根据您的要求生成一个示例，但我一直无法做到。我的程序中其他类似的类不会显示这个错误，我也无法进一步缩小代码中哪些部分导致了这个错误。该应用程序是单线程的。@fabian orderSelected将所选PurchaseOrder中的信息复制到各种文本字段和组合框中。在侦听器处于活动状态的时间内，它不会对列表或属性进行任何更改。因此，您是否在代码中的任何位置使用后台线程？复制此错误的唯一方法是从错误的线程更新表的支持列表。

    private void orderSelected() {
             clear();
             currentPurchaseOrder = orderTable.getSelectionModel().getSelectedItem();
             soldToCombo.getSelectionModel().select(currentPurchaseOrder.getCustomer());
...


private void clear() {
         currentPurchaseOrder = null;
         orderTable.getSelectionModel().clearSelection();
