Just to expand on what suzyb has posted.

This bug only appears when you're using Examine and have set-up another IndexSet (see http://www.farmcode.org/post/2011/03/15/Searching-Umbraco-using-Razor-and-Examine.aspx for the minimum config to set-up a new Examine index).

What appears to happen in the Document_AfterPublish event handler is :-

• UmbracoAPIHelper.CreateContentNode gets called to create the comments folder
• This has a call to UpdateDocumentCache (to add the comments folder) however at this point the comments folder parent (the blog post) hasn't been added to the document cache so this fails. The umbraco api logs ''Couldn't find any page with the nodeId = 0. This is most likely caused by the page isn't published!  Parameter name: nodeId' in the database.
• The new Examine IndexSet causes an event handler to subscribe to the AfterUpdateDocumentCache event. This tries to access properties that should be in the cache but aren't due to the above error - this crashes and causes the ysod

It appears that the simple solution is just to move the UpdateDocumentCache command for the blog post above UmbracoAPIHelper.CreateContentNode and rebuild the dll.

That sounds insteresting.

Good find.

I would also log the issue with examine. 

Cheers.

Has this been fixed in v2.0 of uBlogsy?  Reason I ask is that I'm getting a different, but seemingly similar error in uBlogsy 2.0 and also nForum - in both cases, I get an issue when moving media items in the media section.

See http://our.umbraco.org/projects/website-utilities/nforum/bugs/23610-Error-in-media-section for the error I get when I do this with nForum installed.  When I uninstall nForum, then the nForum error goes away and the new error refers to uBlogsy.  And when I uninstall uBlogsy, the error goes away completely.

Thanks
Allan

Yes I did implement this in 2.0

Strange error.

What packages are installed?

Hi Anthony

In case this was down to a conflict with another package (I have quite a few installed), I installed a fresh instance of Umbraco 4.7 and then installed uBlogsy 2.0 beta and NO other packages at all.  I thought this would be easier than eliminating all the other packages one by one.

I added 2 folders to the media section (Photos and Images) and uploaded a picture (right click Photos, Create, Image).  I then moved the image to the Images folder (right click on the photo in the tree, Move, select Images folder) and got the error below:

Server Error in '/' Application.

After reloading nodes in the media section, the photo had been moved to the correct destination.

I then uninstalled uBlogsy (deleting all the child document types first - which is a pain!!).  Then went back to media and repeated the move process, and the photo moved successfully with no error message.

So it's definitely something to do with the uBlogsy installation - and to me, it seems most likely to relate to:

    uBlogsy.BusinessLogic.EventHandlers.UmbracoExtensions.Document_AfterMove(Object sender, MoveEventArgs e) in D:\_PROJECTS\uBlogsy - Blog\Branches\2.0_comment_subscription\uBlogsy\uBlogsy.BusinessLogic\EventHandlers\UmbracoEventHandlers.cs:125 

I wonder if the same logic as Suzy and Doug were discussing earlier in this post re the Document_AfterPublish event handler also applies to Document_AfterMove?

Ah!

Nice find!

Your crash is due to this:

void Document_AfterMove(object sender, MoveEventArgs e) { Document doc = new Document(((CMSNode)sender).Id); if (doc.ContentType.Alias == "uBlogsyPost") {

I'll fix it in the next release.

Thanks.

Experiencing this issue after copying uBlogsy - Landing content node and child content nodes to new area of site. Can still publish original uBlogsy nodes without any issues.

Using uBlogsy 1.36

Is there a fix without creating a site package?

Hi,

I'm getting the same error. Using Umbraco 4.7.1 and uBlogsy 2.0 (beta2).

I have another examine index. Which if I remove it, stops this error. But I need any solutions available?

Hi Suzy

The same bug was in 2.0 beta 2. Fixed and will be released soon.

Oh that was the stack trace when I create a post... this is the stack trace when I try and publish a post

Oh cheers thanks.. I don't suppose I could get a pre-release of the fix  

Sure

What's your email?

[email protected] thanks :)

Hi all, I'm not sure if the problems we're experiencing is related to all this or not. We've set up a special blog editors role that only has privledges to "send to publish." When those users try to send a blog to publish, they get this .NET error:

The administrative role can publish blog posts with no error.

Any ideas?

Have you tried it with another role?

A work around is to replace the datatype with the standard Umbraco tags datatype. You may loose tags for existing posts though.

Still having issues with ublogsy publishing when having the CWS (creative website starter package) installed.  Trying to see if ublogsy is stable enough to be incorporated into an existing website and am testing by adding it to the CWS package.  

Umbraco 4.7.1.1, uBlogsy 2.0.0.1

I've read the solution posted by suzyb, but have looked at the source code for 2.0.0.1 and the change was made to the uBlogsy.BusinessLogic EnsureCommentsFolder method and is not working.

Any information would be appreciated.  Thanks in advanced.

********UPDATE 2011-03-11 ******************

Was able to remove the CWS examine index and rebuild it.  publishing worked.

Ah I wasnt aware that cws had a custom examine index.

So that was the solution?

I think someone told me that if you upgrade to the newest examine it would have fixed it.

is working on a reply...
