Merge operation
Hi,I have a relation Applicant in which all user details are stored.
I want to give user an option of updating his details so i want to know how
to update Applicant relation in cayenne. Its quite similar like MERGE in JPA
where old date has been replaced if any new changes have been made to the
existing one.Now i want to do this in cayenne..
Thanks in advance

If you are talking about something like a modifiedOn date attribute in the object, then look at the Cayenne listeners for the simplest way to achieve that.
