XPAges："java.io.NotSerializableException: lotus.domino.local.Document"

Question

我有一个 XPage，其中包含一个 Notes 文档。此页面的目的只是显示文档的一些相关字段。

第一次访问该页面是可以的。并且稍后再次显示时无需更改底层文档即可。

但是当我从这个导航到另一个 XPage，并在那里更改文档时（是的，我有另一个页面专门用于编辑文档），然后返回到"show" 页面，我在渲染响应阶段得到 java.io.NotSerializableException。

奇怪：它是为了一个lotus.domino.local.Document ...我从来不想save/serialize一个文件...:-o

我为找到代码中的错误所做的工作：

我在页面的beforeRenderResponse事件中记录了viewScope内容，但是只有简单的对象（字符串和布尔值）。
我把页面的viewState设置为“nostate”。
我把页面的只读属性设置为“true”。
我删除了每个“页面加载”数据绑定（将“${...}”切换为“#{...}”）

那么我还能做些什么来找到代码点，某种文档要保存在哪里？这种情况下的典型错误原因是什么？

感谢您对我的帮助！ :-)

在这两个 XPage 之一上，您将 NotesDocument（不是 DominoDocument 数据源，而是 NotesDocument 对象）存储在一个作用域变量中。 Domino 对象不可序列化，这是引发错误的原因。最有可能的位置是您要从 .

移动的页面

如果您需要访问特定文档，请将文档的 UNID 存储在作用域变量中并使用 database.getDocumentByUNID() 进行检索。这几乎肯定是 DominoDocument 数据源所做的。
