I am trying to set up a trigger to fire when an Account is enabled as a Customer but without success. The after update trigger is not firing at all even after the field "isCustomerPortal" is updated to "true". I also noticed that the LastModifiedDate is not updated after enabling the Account as a Customer.
What is the correct way to set such a trigger ?
Thank you for your help.
Edit : There is no triggers fired for Contacts as well.
