我不知道您的应用程序的确切配置，但是根据您的描述，听起来就像LS抱怨添加新用户时UserApplications为空.

I don't know the exact configuration of your app, but based on your description, it sounds like LS is complaining that UserApplications is empty when you're adding a new User.

我会尝试的:

1. 为用户"表创建一个新的列表和详细信息"屏幕(还包括UserApplications).
2. 添加新用户(无自定义代码，使用LS的默认添加"按钮).
3. 检查以查看是否只能添加一个新用户，而不能添加UserApplications.

1. Create a new List and Details Screen for User table (also include the UserApplications).
2. Add a new User (no custom code, use the default Add button of LS).
3. Check to see if you're able to add just a new User and no UserApplications.
