更新序列号不匹配；请求的USN = 2，数据库USN =3

Question

        ObjectStore objectStore;
        ReferentialContainmentRelationship toRcr = null;
        ReferentialContainmentRelationship fromRcr = null;
        DocumentSet documentSet;
        Iterator documentIterator;
        documentSet = fromFolder.get_ContainedDocuments();
        documentIterator = documentSet.iterator();
        Document document;
        while(documentIterator.hasNext())
            {   

             document = (Document) documentIterator.next();
             toRcr = toFolder.file(document,AutoUniqueName.AUTO_UNIQUE, document.getClassName(),DefineSecurityParentage.DO_NOT_DEFINE_SECURITY_PARENTAGE);

             toRcr.save(RefreshMode.REFRESH);
             toFolder.save(RefreshMode.REFRESH);
             fromRcr = fromFolder.unfile(document);
             fromFolder.save(RefreshMode.REFRESH);
            }

但是，toFolder.save(RefreshMode.REFRESH)；未正确执行，并且即将出现异常

FNServices.getOldFileFolderObject()中出现异常:对象{ADF64C74-F80D-4BD7-8A58-86699C66BFAC}在检索后已被修改。更新序列号不匹配；请求的USN = 2，数据库USN = 3。

在这里，对象指的是创建的新文件夹。

从IBM文档判断，我认为您应该先创建文件夹，然后再考虑归档问题。

ObjectStore objectStore;
    ReferentialContainmentRelationship toRcr = null;
    ReferentialContainmentRelationship fromRcr = null;
    DocumentSet documentSet;
    Iterator documentIterator;
    documentSet = fromFolder.get_ContainedDocuments();
    documentIterator = documentSet.iterator();
    Document document;
    toFolder.save(RefreshMode.REFRESH);
    fromFolder.save(RefreshMode.REFRESH);
    while(documentIterator.hasNext())
        {   

         document = (Document) documentIterator.next();
         toRcr = toFolder.file(document,AutoUniqueName.AUTO_UNIQUE, document.getClassName(),DefineSecurityParentage.DO_NOT_DEFINE_SECURITY_PARENTAGE);

         toRcr.save(RefreshMode.REFRESH);

         fromRcr = fromFolder.unfile(document);
         fromRcr.save(RefreshMode.REFRESH);
        }
