Sitecore 8 Sitecore.Eventing.Remote.PublishEndRemoteEvent

Question

我使用的是Sitecore 8，在停止MongoDB服务并将配置中的设置设置为停止使用MongoDB进行分析后，出现以下特定错误：

ERROR Exception while handling event Sitecore.Eventing.Remote.PublishEndRemoteEvent
Exception: System.NullReferenceException
Message: Object reference not set to an instance of an object.
Source: Sitecore.SharedSource.PartialLanguageFallback
   at Sitecore.SharedSource.PartialLanguageFallback.Providers.FallbackLanguageProvider.ClearFallbackCaches(ItemUri itemUri, Database database)
   at Sitecore.SharedSource.PartialLanguageFallback.Providers.FallbackLanguageProvider.<>c__DisplayClass1.<InitializeEventHandlers>b__0(PublishEndRemoteEvent event)
   at Sitecore.Eventing.EventProvider.RaiseEvent(Object event, Type eventType, EventContext context)

为了禁用分析数据库，我使用了来自here的指示。

PublishEndRemoteEvent会以某种方式使用MongoDB吗？你知道我怎么才能修好它让我再也得不到它吗？

您需要为Sitecore.SharedSource.PartialLanguageFallback生成一个新的程序集，并进行以下更改：

按如下方式更新以下文件: Sitecore.SharedSource.PartialLanguageFallback/Providers/FallbackLanguageProvider.cs

private void ClearFallbackCaches(ItemUri itemUri, Database database)  {
 var cache = _fallbackValuesCaches[database.Name];
 var ignore_cache = _fallbackIgnoreCaches[database.Name];

 if (cache != null)
 {
     // Added a null check on itemUri
     if (itemUri == null)
         cache.Clear();
     else
         cache.RemoveKeysContaining(itemUri.ItemID.ToString());
 }
 if (ignore_cache != null)
 {
     // Added a null check on itemUri
     if (itemUri == null)
         ignore_cache.Clear();
     else
         ignore_cache.RemoveKeysContaining(itemUri.ItemID.ToString());
 }  }
