Tree Behavior gives new child lft and rght values of 0 - cakephp

Question

I have a MPTT using the TreeBehavior in CakePHP. Tree verifies but when I add a new root node it works. When I try to add a child to that node via $this->{Model}->save($data) where $data now has the ['{Model}']['parent_id'] set, it updates the parents' lft and rght fields to accomodate a new child but the new child has lft and rght values of 0.
Any idea of where I might be going wrong?
I have tried setting the lft and rght to null as well as unsetting, to no avail.

Answer 1

You should not specify the lft / rght fields in your save.
Wrong
$this->save(array(
'parent_id' => 123,
'lft' => 0,
'rght' => 0
));
Correct
$this->save(array(
'parent_id' => 123
));
Dont forget to call $this->create(); before the save.
