只设置两级主从的时候显示都正常，但是设置到三级主从的时候，第三级会出现显示异常，表现为在记录之间多次点击之后，第三级会出现不显示（系统提示“自页加载以来出现了一个或多个错误。打开浏览器的 JavaScript 控制台以查看错误。” F12后显示如下截图），需要刷新页面后，才可以正常显示，但是再点击多次后又会出现不显示第三级目录的情况。3个表的关联关系设置如下。大家看看是哪里设置错误有问题? ![](https://cn-oracle-apex.oss-cn-shanghai.aliyuncs.com/file_storage/20251122_EVtoyq4i.png) 错误提示： ![](https://cn-oracle-apex.oss-cn-shanghai.aliyuncs.com/file_storage/20251122_Ij3zwkB2.png) modelViewBase.min.js?v=23.2.0:2 Uncaught TypeError: Cannot read properties of null (reading 'getRecordMetadata')    at q...
