java - JPA (hibernate) does not insert on persist, needs to be flushed -

i have stateless bean observes event , saves record:

@stateless public class manager {     @inject     repository repository;      manager() {}      @inject     manager(repository repository) {         this.repository = repository;     }      public void eventhandler(@observes myevent myevent) {         save(event.obj);     }      private save(object object) {         repository.add(object);     } } 

my repository this:

@stateless public class repository {     @persistencecontext     entitymanager em;      repository() {}      public void add(object object) {         em.persist(object);         // em.flush();  <---     } } 

it doesn’t work unless uncomment line thing don’t understand why need flush! shouldn’t transaction commit automatically?

could have ejb container , cdi transaction started observes never ends weird? or ends doesn’t commit because doesn’t know ejb?

persist() not meant insert row immediately, rather @ flush time, before transaction commit.

however, if not asking, row not inserted after transaction has ended, may flush mode transaction set manual.
