After upgrading from 2015.3.930.45 to 2016.2.607.45 I get an error when using RadAjaxManager.ResponseScripts.Add
If I rollback the upgrade, it works fine.
I've tried using ScriptManager.RegisterStartupScript instead of RadAjaxManager.ResponseScripts.Add and I don't get an error, but it still doesn't work.
Attached is the error when scripts are combined and when they are not.
Any ideas? Again, it works fine if I rollback the update.
