Notes 文档中的 richText 字段重复

Question

我的一些 XPage 上有一个文件上传器。它工作得很好，但使用它有一个严重的缺点。在某些情况下，它会在文档中创建相同字段的 2 个或 3 个或 4 个或 n 个副本。只有当我尝试上传单个文件（或一组文件）并在其后立即执行相同操作时才会发生这种情况。有时在我删除一个文件并上传更多文件后会发生这种情况。保存后文档的字段如下所示。我不知道为什么会这样。

最初我认为可能是因为我忘记在删除按钮中添加 doc_source.save(); 语句。但事实证明这不是原因。

CC的代码如下

这可能只是用于存储 RichText 项目的 Notes 功能？提前致谢。

Answer 1

这确实是 Lotus Domino 存储富文本项或文件附件的方式。 Multiple fields of the same name appear in the Properties box of a Notes document.

如果您的应用可以正常运行，没有其他问题，则无需担心。
