"selected" items in HABTM multiple select

[Olivier Percebois-Garve]

Is there an elegant way to build the list of selected items to feed the $html->selectTag() in a HABTM relation ??

I ended with for instance:

            $materials_selected_designations = array();
            for($i=0; $i < sizeof($this->params['data']['Material']); $i++){
                $materials_selected_designations[$this->params['data']['Material'][$i]['id']] = $this->params['data']['Material'][$i]['designation'];   
            }
            $this->set('materials_selected_designations', $materials_selected_designations);


its not very elegant compared to:

             $this->set('materials_designations',$this->Application->Material->generateList());


The manual doesn't say anything on this, and in the wiki there is only something confuse in understanding_associations.


Any thoughts ??
