Error when saving in Sitecore Backend in the Core Database

Question

After updating our Sitecore 6.3 to 6.6 we are facing the problem that when we want to save an item in the Core DB, this error message comes up:

[NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.]


Sitecore.Intranet.FrontendEditing.FrontendEditor.IsAutoVersioningEnabledForItem(Item item) +69

Saving items in the Master DB works fine. We made the necessary config files changes. Backend and the Website are working fine.

How can I fix this? Thanks in advance :)

Answer 1

Looking at your stack trace - exception is thrown by the Sitecore.Intranet.FrontendEditing.FrontendEditor class. This class is from Sitecore Intranet module.

The last version of Sitecore Intranet module which contains this class is Sitecore Intranet 3.3 (which supports Sitecore 6.3).

This class no longer exists in Sitecore Intranet 4.0 (which supports Sitecore 6.6).

You should update Sitecore Intranet module to 4.0 version

EDIT:

Release History of Sitecore Intranet says:

June 20, 2013

The Sitecore Intranet Platform - SIP v4.0 rev.130523 released on May 23, 2013.

Tested with Sitecore CMS 6.6. rev. 130529 (Update-6) released on June 6, 2013.

Compatibility

This release only runs on Sitecore 6.6 and DMS 6.6.

EDIT 2:

You can try to create a class that will inherit from Sitecore.Intranet.Pipelines.SaveUI.AddNewVersion and catch this exception. It should not be executed for core database anyway.

Remember to register your new class instead of original 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);
            }
        }
    }
}
