How to display the changed by user

I need help about displaying the changing by user (or track the manipulations) on an entity instance like by example I have an entity in the domain model called application , on the application entity there are several actions like refuse application , accept application , assign application , I need to track the changes on this entity (changed by , changed at , etc) I have figured out how to do it but it’s displaying all the application entity instances , so my problem is that the changed by and change at are displaying for all the applications and not a single application instance. Please to help me figure it out and thank you.

How did you create the page that is displaying the information. You should be able to constraint the result by xpath or by doing retrieve by association.

How is your data structure looking?
