添加不受支持的 CheckComboBox 控件后，如何在 Scene Builder 中打开 FXML 文件？答案

【问题标题】：How to open an FXML file in Scene Builder after adding an unsupported CheckComboBox control?添加不受支持的 CheckComboBox 控件后，如何在 Scene Builder 中打开 FXML 文件？
【发布时间】：2016-10-21 19:23:02
【问题描述】：

我正在使用 IntelliJ IDEA 和 Scene Builder 开发 JavaFX 应用程序。为了创建具有多项选择的组合框，我已将 controlsfx.jar 库导入到 Scene Builder 和我的项目中，并计划使用它们提供的 CheckComboBox 控件，如建议的here。

当我将库导入到 Scene Builder 时，CheckComboBox 控件不在加载的控件中。所以我编辑了 FXML 文件并通过编写的代码将其插入。

不幸的是，执行此操作后，我无法再在 Scene Builder 中打开 FXML 文件。当我尝试直接从 Intellij IDEA 打开时出现此错误：

虽然我有 Java 版本 8 Update 91...

我真的很想继续使用 Scene Builder。我该怎么办？

谢谢！

【问题讨论】：

当您打开第一个 Scene Builder 并从那里加载 FXML 文件而不是从 IntelliJ 打开时，是否也会发生这种情况？
是的，它以两种方式发生。
您的 Scene Builder 版本是多少？
版本：2.0-b20。
可以升级到 Scene Builder 8.2.0 吗？ gluonhq.com/labs/scene-builder

【解决方案1】：

感谢José Pereda，我切换到another version of Scene Builder，我的问题消失了。我现在可以将 CheckComboBox 控件与 Scene Builder 一起使用。
