如何在添加不支持的CheckComboBox控件后在Scene Builder中打开FXML文件？

Question

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

当我将库导入Scene Builder时，CheckComboBox控件不在加载的控件中。所以我编辑了FXML文件并通过编写代码插入它。

不幸的是，在执行此操作后，我无法在Scene Builder中打开FXML文件。当我尝试直接从Intellij IDEA打开它时会发生此错误：

虽然我有Java Version 8 Update 91 ...

我真的想继续使用Scene Builder。我该怎么办呢？

谢谢！

感谢José Pereda，我切换到another version of Scene Builder，我的问题就消失了。我现在可以在场景生成器中使用CheckComboBox控件。
