无法保存非当前版本-Umbraco 8

我在以编程方式保存内容时遇到问题，我单击电子邮件上的链接，然后我被带到该站点，在这种情况下，CMS会更新。但是，如果我再次单击该链接，则会出现以下错误：

无法保存非当前版本

"   at Umbraco.Core.Persistence.Repositories.Implement.DocumentRepository.PersistUpdatedItem(IContent entity)\r\n   
at Umbraco.Core.Cache.DefaultRepositoryCachePolicy`2.Update(TEntity entity, Action`1 persistUpdated)\r\n   
at Umbraco.Core.Persistence.Repositories.Implement.RepositoryBase`2.Save(TEntity entity)\r\n

at Umbraco.Core.Services.Implement.ContentService.SaveAndPublish(IContent content, String culture, Int32 userId, Boolean raiseEvents)\r\n   
at Web.Controller.Controllers.ContactController.CoachConfirmed(String id) 

在V7中，我通常能够执行ApplicationContext.Current.Services.ContentService.Republichauld（）；，但是V8似乎不再有这种选择了

任何帮助都将不胜感激

这似乎是Umbraco中的一个bug，根据，修复程序将在8.3.0版中推出

var contentService = Services.ContentService;
                        var content = contentService.GetById(new Guid(coachDocType));

                        content.SetValue("numberOfTrainees", newNumberOfSpaces);
                        content.SetValue("numberOfTraineesFollowing", newNumberOfSpacesTaken);
                        contentService.SaveAndPublish(content);
