I developed my code starting from here: http://realm3.com/articles/drag_and_drop_trees_with_cakephp At the end of the page there's a "save" function and my code is almost equal to that one. $category = $this->Category->find('first', array('conditions' => array ( 'Category.id' => $this_node_id) )); $this->Category->set($category); if (isset($category['Category']['id']) && $category['Category'] ['parent_id'] !== $this_node_parent_id) { $ret = $this->Category->save(array('parent_id' => $this_node_parent_id)); (the names of the variables are obvious.) The original code used SetParent that, as you know, is deprecated now. I didn't use $this->Category->id = 1234 before $this->Category->save () because I presumed that find('first') would have the same effect with the ActiveRecord approach. But I could be totally wrong on this. And because, before adding the isUnique validation rule, my "save" function did work. Anyway, I just added $this->Category->id=1234; before $this->Category- >save() and the problem is still there. :-( Thank you maxx Check out the new CakePHP Questions site http://cakeqs.org and help others with their CakePHP related questions.
