By default, the Personalization module comes with two action handlers configured:
/atg/registry/EventHandlers/actions/AssignLastActivityAction, which automatically sets a value of thelastActivityprofile attribute on login/atg/registry/EventHandlers/actions/AssignRegistrationDateAction, which automatically sets a value of theregistrationDateprofile attribute on registration
If your profile template does not include the lastActivity and registrationDate attributes, then the presence of these action handlers can cause errors. To disable these action handlers, set the registerAtStartup property to false on the /atg/registry/EventHandlers/LoginHandler and /atg/registry/EventHandlers/RegisterHandler components.
