RavenDB 4 - Unable to edit index

[Andrej Krivulčík]

When I edit an index in the studio, the save succeeds, but the index is not correctly created. I *think* that I encountered this even when executing an index from client code, but here's how I can reliably reproduce this issue:

1. Create a new database with Northwind data (I created two: http://4.live-test.ravendb.net/studio/index.html#databases/documents?&database=northwind-test-andrej and http://4.live-test.ravendb.net/studio/index.html#databases/documents?&database=northwind-test-andrej2 ).
2. Edit the index Orders/ByCompany (I changed the Count = 1 to Count = 2 in Map part).
3. The index is correctly saved and works correctly. It can be queried, the counts are double as expected, and the index is not stale so I assume that it is deployed. The indexing performance screen doesn't show any meaningful data, I'm not sure if this is important.
4. Edit the index Orders/ByCompany again (I changed the Count = 2 back to Count = 1).
5. The index seems to be saved correctly (green confirmation message is shown), but it's not.

The following indexing error is created (note the MinValue in Timestamp):

Index Name: Orders/ByCompany

The index is shown twice in the index list - one time under Orders, one time as faulty under Other.

In effect, the index definition cannot be retrieved from the server (can it? how?) and the index doesn't work anymore.

Yes, this is a known issue that will be fixed when we upgrade live test to the RC release.

Something locked the file? Do you have two dbs with the same path?

[Victor Potatis Maximus]

Would the current setup cause this issue?

Server\RavenData\Databases\db1

Server\RavenData\Databases\db2

Server\RavenData\Databases\db3

I'm currently experiencing this issue on 4.0.3.

Thanks

[Oren Eini (Ayende Rahien)]

Did you define any custom temp paths?
