Only RelatedJoin can do add/remove and use addRemoveName. SingleJoin
cannot add objects. And BTW where are backreferences (ForeignKeys) for
every SingleJoin?
What you probably want is the following:
class Line(SQLObject):
owner = ForeignKey('Scene')
text = UnicodeCol()
prev = ForeignKey('Line', default=None)
next = ForeignKey('Line', default=None)
created = DateTimeCol(default=datetime.now)
line1.next = line2
