検索結果をPaginationする時

app\Controller\XxxxxController.php

public function search() {
	$this->Prg->commonProcess();

	$this->Paginator->settings = array(
		'conditions' => array(
			$this->Model->parseCriteria($this->passedArgs)
		)
	);
	$this->set('lists', $this->Paginator->paginate());
}

Paginationしない時

app\Controller\XxxxxController.php

public function search() {
	$this->Prg->commonProcess();

	if ($this->request->data) {
		// 検索結果の表示
		$passedArgs = $this->passedArgs;
	} else {
		// 検索しない時の表示
		$passedArgs = null;
	}
	$lists = $this->Model->find('all', $passedArgs);
	$this->set('lists', $lists);
}
