sitecore - 在核心数据库的 Sitecore 后端中保存时出错

Question

将我们的 Sitecore 6.3 更新到 6.6 后，我们遇到了一个问题，即当我们想在核心数据库中保存一个项目时，会出现此错误消息:

在主数据库中保存项目工作正常。我们进行了必要的配置文件更改。后端和网站运行良好。

我该如何解决这个问题？提前致谢:)

Answer 1

查看堆栈跟踪 - Sitecore.Intranet.FrontendEditing.FrontendEditor 类抛出异常。此类来自 Sitecore Intranet 模块。

包含此类的 Sitecore Intranet 模块的最新版本是 Sitecore Intranet 3.3(支持 Sitecore 6.3)。

Sitecore Intranet 4.0(支持 Sitecore 6.6)中不再存在此类。

您应该将 Sitecore Intranet 模块更新为 4.0 version

您可以尝试创建一个继承自 Sitecore.Intranet.Pipelines.SaveUI.AddNewVersion 的类并捕获此异常。无论如何，它都不应该为 core 数据库执行。

请记住注册您的新类而不是原来的AddNewVersion:

    <!-- processor mode="on" type="Sitecore.Intranet.Pipelines.SaveUI.AddNewVersion, Sitecore.Intranet" / -->
    <processor mode="on" type="My.Assembly.Namespace.AddNewVersion, My.Assembly.Namespace" />

namespace My.Assembly.Namespace
{
    public class AddNewVersion : Sitecore.Intranet.Pipelines.SaveUI.AddNewVersion
    {
        public new void Process(Sitecore.Pipelines.Save.SaveArgs args)
        {
            try
            {
                base.Process(args);
            }
            catch (Exception exc)
            {
                Log.Error("Exception in AddNewVersion.Process", exc, this);
            }
        }
    }
}
