DB change not reflected in collection

[measwel]

LS,

I have a User entity that holds a collection of Favorite entities. When I add a favorite or remove a favorite in the db (via the favorite entities jpa controller) then I do not see this change reflected in the User's collection of Favorites, even though the fetch type is set to EAGER of the collection. Can somebody explain me what I am doing wrong?

Thank you,
MPK

You must always update both sides of the relationship,

Your JPA provider is probably also caching, so you may desire to turn off the cache, or call refresh().
