tfs-2015 - 在 TFS2015 中重新排序积压优先级时出错

Question

在 TFS 中的待办事项列表中，您可以根据所需的顺序通过选择和拖动项目来重新排序工作项目。当我们尝试使用最近的 TFS 2015 安装执行此操作时，会弹出此错误: 其中说:

An error has occurred while attempting to save your changes. Click here to discard your changes and refresh your view of the backlog. Error details: TF400486: Unable to complete the operation because you or another user has modified, removed, or re-parented items, or you are trying to reorder an item outside of its immediate parent.

当我们查看TFS机器上的事件日志时，出现了这个异常:

Microsoft.TeamFoundation.Server.WebAccess.Agile.Models.BacklogChangedException: TF400486: Unable to complete the operation because you or another user has modified, removed, or re-parented items, or you are trying to reorder an item outside of its immediate parent. at Microsoft.TeamFoundation.Server.WebAccess.Agile.Utility.ProductBacklogReorderHelper.PerformReorder(ReorderOperation operation, WorkItemData previousItem, WorkItemData nextItem, WorkItemData reorderItem, List1 workItemsData) at

我们应该采取什么步骤来解决这个问题？

Answer 1

你可以试试:

1. 将 TFS 2015 升级到 TFS 2015 Update 1。

2. 清理 AT 机器上的文件缓存文件夹:C:\TfsData\ApplicationTier_fileCache

3. 在 IIS 中重新启动 TFS 应用程序池。
