"delete-orphan" would mean that a Post object which does not have a parent Post object would not be allowed to exist. which in the case of a tree structure makes no sense since there could then be no root. p.s. i took out the "delete-orphan" from the self-referential docs. ------------------------------------------------------------------------- Take Surveys.
