You're using the wrong method. Look at the API:
http://api.cakephp.org/class/tree-behavior#method-TreeBehaviorgeneratetreelist
"A convenience method for returning a hierarchical array used for HTML
select boxes"
IOW, it returns data in the same format as find('list'), ie. $id =>
$name. You should use find('threaded', $filters), where $filters is an
array with the usual 'conditions', 'fields', etc. arrays. You can even
use 'contain' as you would normally. Each Projecttask (shouldn't that
be ProjectTask?) entry will have a 'children' key pointing to an array
of Projecttasks (if any).

> $deleteurl = $html->link("Delete", array('action'=>'delete',

You should take a look at Andy Dawson's TreeHelper, which takes the
pain out of creating nested lists from nested tree data. I found it a
bit confusing at first but it works great.
