OIM11g: Notification Event, before and after data elements

Question

Hello
I have several notification events currently working correctly. I would like to, however, create a new notification event that contains the before and after value of a changed attribute.
For example: if user email address changes, notification should be similar to:
This is a notification that your email address has been successfully updated in the system. Old value: [email protected] New value: [email protected]
Notifications seem to only be fired as post process event handlers, process tasks, and scheduled tasks, is it possible to have both the before and after datasets available to the notification in any of these tasks?
Thank you.

If it's on a user object field, you can check for if the attribute you are watching is contained in the orchestration.getParameters(). If it is found, you can pull the old value out of the following:
HashMap eventDataHashMap = orchestration.getInterEventData();
Identity currentUserState = (Identity) eventDataHashMap.get("CURRENT_USER");
Then you can generate the email/notification however you'd like.
