如何修正随机变量；oracle.jbo.uicli.binding.JUCtrlHierBinding.brignodetorangekeypath中的java.lang.NullPointerException；错误

我正在使用OracleADF创建一个webapp，我有父实体和子实体，所以发生的是，我随机得到下面的错误，我无法重现该场景

我使用此库时，从line FacesContext.getCurrentInstance（）获取时出错，在将日志放入支持bean中的每个函数以及库中的每个函数后，退出函数后会发生错误，因此我猜我的函数不会调用此错误

我已经尝试了各种可能的方案来重现错误，但没有明确的方案来帮助我解决错误。

嘿，Wissam，请尝试将oracle.adfinternal和oracle.jbo的日志级别设置为FINEST并重现。您将获得触发此错误的组件的更多详细信息。您好，感谢您的快速响应我已经有了日志，并且从FacesContext.getCurrentInstance（）获得了空指针异常这也会随机引发空指针异常。能否使用调用此FacesContext.getCurrentInstance（）的代码更新问题？这是用豆子做的吗？在标准adf组件中？etcwe使用这个库时，从line FacesContext.getCurrentInstance（）中获取错误，在将日志放入支持bean中的每个函数之后，错误在退出它们之后发生，因此我的函数不会调用该错误。我可以发布我的bean和Jsf，但它们太长，太分散注意力。但是正如我所说，在退出bean函数后会抛出错误。嘿，Wissam，尝试将您的oracle.adfinternal和oracle.jbo的日志级别设置为FINEST和reproductive。您将获得触发此错误的组件的更多详细信息。您好，感谢您的快速响应我已经有了日志，并且从FacesContext.getCurrentInstance（）获得了空指针异常这也会随机引发空指针异常。能否使用调用此FacesContext.getCurrentInstance（）的代码更新问题？这是用豆子做的吗？在标准adf组件中？etcwe使用这个库时，从line FacesContext.getCurrentInstance（）中获取错误，在将日志放入支持bean中的每个函数之后，错误在退出它们之后发生，因此我的函数不会调用该错误。我可以发布我的bean和Jsf，但它们太长，太分散注意力。但正如我所说，这个错误是在退出bean函数后抛出的。
