- Rebuilding Examine indexes

Still lost...

Issue reported here: http://issues.umbraco.org/issue/U4-4591#

Same problem with version 7.1.0

Ensure that you do not have two tabs (or potentially properties) with the same name inside your nested document types.

Eg. Master document type has a specific tab and a sub document type has a tab of the same name.

Same problem in 7.2 alpha b118

I just had the same issue and on investigation discovered that it was caused by a duplicate tab name on an inherited child document type.

I'm getting this after upgrading from 7.1.8 to 7.2.1, and I have no nested/descendant document types (i.e. each document type stands alone). Creating new content nodes invokes the error, but editing existing nodes works fine. Will try the "export/import/re-assign new document type to existing nodes" idea from @Arie at http://our.umbraco.org/forum/umbraco-7/using-umbraco-7/53247-Failed-to-retrieve-data-for-empty-content-item-type-ArticlePageOldCopy?p=0

I got the "Failed to retrieve data for content id XXXX" error for some nodes of a certain content type but not others, so it obviously was not the content type.

I found that the error appeared for the nodes that were updated by a user that was no longer in the system (writerID="96"​). The ones that were updated by a valid user worked fine. Since you can't edit the problem nodes you need to re-publish the entire parent node with sub nodes. It fixed the problem for me.

If this can be confirmed I would say it's a bug in Umbraco. You need to be able to delete users without breaking nodes they have created or edited.

I'm seeing the same now on 7.3.5 - anyone closer to finding out the issue? We're in the process of hooking up the source to trace it through and see if it's a quick fix

Received an error from the server Failed to delete item 33151

Sequence contains no elements

Hi All,

As Simon Steed mentioned -we've traced this through and (for us) what seemed to be the issue: was there was no recycle bin in the umbracoNode table. Basically, when doing a delete (as shown in the stacktrace) the unpublish and updatecache operations went through okay, but when Umbraco.Core.Services.ContentService.Umbraco.Core.Services.IContentServiceOperations.MoveToRecycleBin(IContent content, Int32 userId) is called, using Poco a query is run looking for node with id -20, on which the code does .First(), except that nothing is returned leading to this "sequence contains no elements" exception shown in the stacktrace.

For us, using a local test database, I was able to put the Recycle Bin back in as I believe it should have been (I installed a fresh Umbrao 7.3.5 for reference so I knew what values they should be, doing:)

SET IDENTITY_INSERT [websiteDB].[dbo].[umbracoNode] ON
GO

INSERT INTO  [websiteDB].[dbo].[umbracoNode]
( id, trashed, parentID, nodeUser,level,path,sortOrder,uniqueID,text,nodeObjectType,createDate )
VALUES (-20,0,-1,0,0,'-1,-20',0,'0F582A79-1E41-4CF0-BFA0-76340651891A','Recycle Bin','01BB7FF2-24DC-4C0C-95A2-C24EF72BBAC8','2012-10-19 12:39:15.477')

SET IDENTITY_INSERT [websiteDB].[dbo].[umbracoNode] OFF
GO

We can now delete nodes quite normally after this operation - but I am very keen to understand how this scenario came about. We've not made any manual updates to the database like this. Just to give you all some background: the site was originally Umbraco 4.11.10 - we used the upgrade to Umbraco 7.3.0 which we later did a minor update to 7.3.5 (to escape some caching issues) and it was very recently we then noticed we couldn't delete items.

I'm not sure if this is the same thing others were experiencing but wanted to post what I found in case it did relate in some way,

Kind regards,

Just throwing in another "me too". I created a list view tab name called "Events" Which was the same name of the parent docType. Renamed it to Event List and it started working again.

I recently had to deal with this issue with grid layout content.

After uploading the latest build to the staging environment, any Document Type using that property had stopped working. I was getting the error "Failed to retrieve data for ..." in the Content and Settings sections of Umbraco.

As my local environment was working as normal, I noticed that the Document Types all had an RJP.MultiUrlPicker property, not inherited or shared, which I had recently updated.

On the staging environment, I noticed I was also getting the error, "Failed to retrieve data for ..." when trying to edit any RJP.MultiUrlPicker Data Type.

So in my local environment I decided to re-save any Data Type of RJP.MultiUrlPicker and perform a full export via uSync.

Uploading and importing the full uSync export on the staging environment and everything was working again.

Hope this helps anyone who has a similar issue.

is working on a reply...
