我使用Scene Builder构建了一个场景，但在尝试使用FXMLLoader打开fxml文件时出现了一些错误。我的JavaFX版本是2.2.55-b13。这是我的fxml：

指定的行对我来说没问题，我在其他fxml文件中使用了一些这些属性，它们在那里工作得很好......
答案 0 :(得分：2)
我通过删除：
解决了这个问题<opaqueInsets>
<Insets bottom="20.0" left="20.0" right="20.0" top="20.0" />
</opaqueInsets>
我的实际JavaFX版本与SceneBuilder的版本之间似乎存在一些兼容性问题
