Java SceneBuilder节点不可选择

在我的JavaFX应用程序中，一些节点显示在预览中，但不可选择，也不显示在层次结构中。SceneBuilder非目标示例：

在本例中，First Name列不可作为目标，即使其代码与Last Name列相同，也不会显示在层次结构中。 新的也一样。。。编辑。。。按钮

我的SceneBuilder版本是8.3.0。 我使用的是eclipse，如果必须手动操作，我将通过FXGraph编辑fxml

FXML：

在FXML中的多个位置，重复定义相同标记的内容，如以下代码段：

<columns>
   <TableColumn fx:id="firstNameColumn" prefWidth="75.0" text="First Name"/> 
</columns>
<columns> <!-- repetition!! -->  
   <TableColumn fx:id="lastNameColumn" prefWidth="75.0" text="Last Name"/> 
</columns>

这是不正确的-您应该打开标记一次，然后指定所有子项，然后关闭它一次。对于GridPane的子项，您的操作是正确的，例如：

<GridPane layoutX="67.0" layoutY="78.0" AnchorPane.leftAnchor="5.0" AnchorPane.rightAnchor="5.0" AnchorPane.topAnchor="30.0"> 
    <children>
        <Label text="First Name"/> 
        <Label text="Last Name" GridPane.rowIndex="1"/> 
        <Label text="Street" GridPane.rowIndex="2"/> 
        ...
    </children>
</GridPane>

根据我的经验，JavaFx本身接受in，并按预期显示一些非常有趣的FXML构造，但SceneBuilder倾向于更保守，只接受典型的构造。这可能就是预览看起来不错，但层次结构不完整的原因。如果手动编辑FXML，请首先查看SceneBuilder创建相同结构的方式—这是它所期望的方式

如果在所有位置更正嵌套，则生成的FXML为：

这在SceneBuilder 8.4.1中提供了所需的结果：所有表格列和按钮栏中的所有按钮都将在层次结构中显示并可选择。

您使用的是哪个SceneBuilder版本？网格窗格显示61行13列？你真的都有吗？当您选择网格窗格时，是否看到它？您有一个名为“LastName”的列，但没有名为“First Name”的列。“LastName”列是否可选？@JoséPereda我的SceneBuilder版本是8.3.0。61行和13列都是奇怪的未使用代码，我不确定它们来自何处，也许我也在使用FXGraph导致了奇怪的交互。否则网格窗格工作正常。@Kerry姓氏列按插入方式工作，可以选择。您能尝试删除或清除该代码吗？我确实从头开始尝试过使用拆分窗格和TableView的布局，但我无法重现您的问题。
