我遇到了以下异常，甚至不知道它出现在哪个位置。这是什么意思呢？

先生，有任何要发表的代码吗？ - Elltz
@Elltz 我有大约30个与JavaFX相关联的类。哪一个？我得说 - 我甚至都不知道看哪一个。 - Pavel_K

似乎你在布局过程中遇到了异常，所以每次都会发生异常。请创建一个最小可复现示例并发布它。否则很难找到问题的所在... - fabian
第一个异常与其他异常不同，并且似乎发生在某个“Text”节点上。如果您明确拥有“Text”节点，我会从那里开始检查。正如@fabian所指出的，这些异常发生在布局期间。即使您有大量的类，您可以假设独立于彼此显示由其中一小部分类表示的布局子集，因此您可以缩小异常的原因。 - James_D

我也遇到过这个问题，想写一下我是如何解决的。答案是：我在非JavaFX线程中编辑了GUI。我绝对相信我没有这样做，但事实上我确实是这样做的。如果你遇到这个问题，请检查你的代码，使用 Platform.runLater() 在正确的JavaFX线程中运行GUI更改。
