The Check Account Activationtrigger checks if account activation is used and if the account to be activated is unique. It also checks whether or not the account has already been activated by someone else.
Generally, this trigger is automatically created by the User Registration Wizard or by the Create Activation Page server behavior.
It is possible to manually create your own activation page with the Update Record Transaction and the Check Account Activation trigger (to check the activation status of a user before the update occurs). Both of these actions though can be performed simultaneously with the Create Activation Page server behavior.
Access the trigger from the Application
panel, Server Behaviors -> + -> MX Kollection
-> User Login -> Advanced -> Check Account
Activation.
An example of the trigger interface can be seen below:

For instructions on completing this dialog box, see the Advanced tab. For the Check Account Activation trigger, by default the Priority is set to 1 and the Type is BEFORE, as it should execute before the transaction takes place.
Note: If you use this server behavior
on the ColdFusion server model, a file named
Application.cfm will be automatically generated
in the site root folder. Do not delete this file, as it contains settings
related to session variables used by the server behavior and the current
application. If you remove this file or modify it, application pages that
use sessions will not function properly.
