多FileDownload控件多次删除后Xpages文档无法保存问题

我开发了一个包含多组FileUpload和支持删除操作的FileDownload控件的XPage，执行以下操作后点击Save按钮会出现保存失败：

• 为第一个字段添加附件，删除后重新添加附件；
• 为第二个字段执行同样的添加-删除-重新添加附件操作；
• 点击Save按钮。

报错提示保存数据源document1时发生异常，底层为NullPointerException，堆栈指向DominoRichTextItem类的updateMultipartRelated方法。经测试，仅使用一组控件时无此问题；排查发现问题与Xsp Properties中启用org.openntf.domino.xsp.XspLibrary库相关。
