Hi!

We are refactoring some code and and changing namespace on our visitor groups. This makes the startup crash with this exception:

My guess is that I need to remap the vistor groups in the db, can that be done with changing namespace directly in the database?

Could I use the EPiServerDataStore attribute maybe?

Thanks!

Hi!

Got this from Episerver support and it solved my problem.

Please run the following call on your local DB first ( you can keep the backup of local as well ) and if everything works then later you can raise a ticket with us if you want to run it on any other environment.

exec [dbo].[BigTableDeleteAll] 'VW_VisitorGroup'

I had the same issue, not on initialization though, but when trying to create/update visitor groups created based on these custom criterion. The front end of the site throws "Failed To Bind Model" error on Vist\itorGroup/Save or Update POST calls :

And in logs, i see the same Value is null exception :

I tried the above suggestion from Epi on local DB, but it essentially deleted all my existing visitor groups (which i see as a problem on an upgrade site where original live site has several Visitor groups created and assigned to content). And i can't create any new ones using custom criterion still because of the same error as above.

Please advice!

Regards

Ritu
