  <?echo $this->element('produtos-categoria',     array('categoria_id' => $produtos['produto']['categoriasproduto_id'],     'produto_id' => $produtos['produto']['id'])); ?>

but i'm not able second value in controller, first value coming: 

public function listacategorias($categoria_id = null, $produto_id = null ) {         pr($produto_id); exit;         //$produtos = $this->produto->findbyslug($produto_id);         //$produtosrelacionados = $this->produto->find('all', array('conditions'=>array('produto.categoriasproduto_id' => $categoria_id)));         //$this->set(compact('produtos'));         //$this->set(compact('produtosrelacionados'));         //return $produtosrelacionados;     }

the result of print empty.
