U4-2463 - Examine index fails when supportUnpublished=true

Created by Alex Wilks 04 Jul 2013, 15:14:12 Updated by Mark Bowser 04 Mar 2017, 00:23:21

Relates to: U4-9598

We have a webservice that needs to search all nodes and publish any items it finds that are currently unpublished. I have created an index with supportUnpublished=false and it is created without any issue. Over 1200 nodes, as expected.

When changing supportUnpublished to true and rebuilding the index via the Examine Management tab, an alert error occurs saying "error: The index could not be rebuilt at this time, most likely there is another thread currently writing to the index. Error: System.NullReferenceException: Object reference not set to an instance of an object".

The index has few, if any, items in it.

Unfortunately, I can't reproduce. 29 nodes, 4 of which are unpublished. All 29 of them get indexed. This may have been fixed already in 6.1.2 or in the upcoming 6.1.3 (where I tested your configs from the forum thread).

Did you ever find a solution to this? I'm currently having the same issue. Running 6.1.3, started at 6.0.

Same thing here with Umbraco 6.2.0-RC

Is this possible to reopen this issue?

@duge Try 6.2.0 final, it was just released http://umbra.co/1fBsUS7

@sebastiaan Will do today!

@sebastiaan I've updated my binaries to v6.2.0 and having the same issue loading my site the first time. The internal index stucked when starting. If I change the supportUnpublish to false, it is working... Any ideas?

I had the same problem with 7.4.3. With supportUnpublished=true almost nothing gets indexed. With supportUnpublished=false everything gets indexed ok except the unpublished.

I finally solved it by removing all my IndexSet custom configurations (IndexAttributeFields, IndexUserFields and IncludeNodeTypes). Not sure which one was causing the problem.
