Instance found more than once

[boskop]

Hello,

I've a problem with Hibernate in my Webapplication. So I've a class Log with a unidirectional one-to-many reationship to LogEntries.

In Log:

@OneToMany(cascade=CascadeType.REMOVE, fetch=FetchType.EAGER)
    @JoinColumn(name="log_id")
    private final Set<LogEntry> logEntries = new HashSet<LogEntry>();

In LogEntries, I've no reference to Log, because it's unidirectional.

In my Example I use an instance of Log that contains 4 Instances of LogEntry. When I now load my Log instance, HibernateTemplate returns me a list that contains my Log four times... That's not what I expected.

public List<Log> findBy(Date logDate) {
        DetachedCriteria c = DetachedCriteria.forClass(Log.class);
        c.add(Restrictions.eq("logDate", logDate));

        List<Log> logs = getHibernateTemplate().findByCriteria(c);
        return logs;
 }

It seems that every LogEntry loads the Log once more and at the end Hibernate finds four times the log. But it is four times the same instance.

What's going wrong?

Mike

Ok, I've found the solution.

It works as designed. The description can be found here:
