如何在视图条件之外的 selectManyChoice LOV 中允许选择然后取消选择

Question

这是我的问题。

我在表单中得到了 selectManyChoice（这不是查看条件的一部分）。一切正常，除非用户 select 1 个或多个条目，他们不能 deselect 全部，否则我会收到 PPR 异常。

我的设置是一个基于查询的简单 LOV，它在我的 AM 数据模型中可用，我只是将 LOV 从我的数据控件拖到我的表单到 selectManyChoice。 selectManyChoice 在自动提交中，因为我还有一个需要提示的 onValueChangeListener。

没有我的 onValueChangeListener，我仍然以同样的方式得到错误（selecting 一些东西然后 de-selecting 一切）

将 selection 留空不会产生任何错误并让表单正常使用，但是 selecting 一些东西然后 de-selecting 它会导致错误...

出于信息目的，我使用 jDeveloper 版本 11.1.1.9.0

提前致谢！

这是启动的 PPR 错误，以备不时之需
