Viknes B commented on RAVE-690:
-------------------------------
I added the @Transactional annotation and the values are getting persisted.
But strangely the values already present in the DB were getting deleted.
so i enabled the SQL logs to see wht was happening and i found out these 2
queries were getting executed.
[INFO] [talledLocalContainer] 656517 ravePersistenceUnit TRACE [http-8080-8]

[INFO] [talledLocalContainer] 656518 ravePersistenceUnit TRACE [http-8080-8]
openjpa.jdbc.SQL - <t 2085407535, conn 1950175420> executing prepstmnt
181365271 DELETE FROM person_association WHERE follower_id = ? [params=?]
This is because of the ManyToMany mapping in the JpaPerson class to get the
list of friends.
But this variable 'friends' is never used any where in Rave and also it
actually does not get the list of friends.
So i removed this variable, mapping and then tested the addfriend functionality
and it is working fine.
1. Is it ok if i remove this mapping variable?
2. I guess delete queries like the above are executed when a @JoinTable is
present. Can anyone tell me why?

> Currently we can display friend data in rave but there are no methods to
> add/delete friend from open social data in Rave. It would be good to have
> friend operation in rave and display them into user profile page.
