well, I would set the Arrays that should be converted to the Itearator
objects to a special viewVar, i.e.:
In your Controller action
<?php
$iterators = array();
$cars = $this->Car->find('all');
$trucks = $this->Truck->find('all');
$iterators = Set::merge($iterators, $cars, $trucks);
$this->set(compact('iterators'));
?>
In AppController::beforeRender(), this way you can use this everywhere
if you add to the iterators viewVar
<?php
$iterators = empty($this->viewVars['iterators']) ? array() :
$this->viewVars['iterators'];
foreach($iterators as $alias => $data) {
$iterators[$alias] = ArrayConverter::createAggregator($data);
}
$this->viewVars['iterators'] = $iterators;
?>
ArrayConverter is a library class in 'app/lib/array_converter.php' that
you can load with App::import().

Thomas
