Hi

Before I merge an updated entity I need to be able to check if some of the 
fields have changed. I need to execute some code in my entity listener 
depending on whether or not a particular field has changed.

e.g. I have a field userID which links to a user entity. In my preUpdate method 
I need to send an email to the user if the field has changed. I wouldn?t want 
to send the email every time the entity is updated.
