    Basically, persona is from a different DataContext, so
    CayenneConnection.dataContext is having trouble deleting it. You can use

    CayenneConnection.dataContext.localObjects(Collections.singletonList
    (persona))

    to get a copy of the object local to this DataContext which it should
    be possible to delete.
