You may have more luck if you set up an additional Relationship
association (you can use contain to not include it in finds later on),
and then have the condition that denotes whether it's a Father or
Child in the form, eg:
echo $this->Form->input('Relationship.0.id');
echo $this->Form->input('Relationship.0.name');
echo $this->Form->hidden('Relationship.0.type',
array('value'=>RelationShipTypeFather);
echo $this->Form->input('Relationship.1.id');
echo $this->Form->input('Relationship.1.name');
echo $this->Form->hidden('Relationship.1.type',
array('value'=>RelationShipTypeChild);
Cheers,
Jon
