    Ok. thx

    ps: why do you use setUser() or addToVisitorList() methods?
    Is it not better to use setToOneTarget() or addToManyTarget()? I thought
    this will saves you to create the inverse relationship!

    No, you'd have to associate the visitor with a particular user
    somehow. By default the relationship will be null.

    visitor.setUser(user)

    or

    user.addToVisitorList(visitor)
