我们正在使用 OC4J 10.1.3.5 和 ADF。我有一个弹出表单，关闭时出现以下错误。我想知道我错过了什么，我该如何解决？

Answer 1

从文档:

IllegalStateException signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation.

没有解决这些异常的 Elixir ；您必须逐案处理，研究您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，它看起来像 popView()当堆栈为空时被调用。您可能缺少一个 pushView ，或错误计算推送次数与弹出次数。
