We are using OC4J 10.1.3.5 and ADF. I have a popup form and when closing we got error below. I wonder what am I missing and how can I resolve it?

从文档中：
没有什么灵丹妙药可以解决这些异常情况。你必须根据具体情况进行处理，研究你正在使用的任何库的 API，并找出非法状态发生的位置。
在这种特殊情况下，看起来当堆栈为空时
popView()正在被调用。您可能缺少pushView，或者错误计算了推送与弹出的数量。From the documentation:
There's no silver bullet to resolve these kinds of exceptions; you have to deal with it on a case by case basis, studying the API of whatever library you're using, and figuring out where the illegal state happens.
In this particular case, it looks like
popView()is being called when the stack is empty. You may be missing apushView, or miscalculating the number of pushes vs pops.
