Remap custom created visitor groups?
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'

Hi
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 :
System.ArgumentNullException: Value cannot be null. (Parameter 'type')

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!

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

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!
