To call a view from our component's controller:

$this->_view->renderizar('vista');

$this->_view->renderizar('vista',true);
       La bandera true agrega el header y footer por defecto de la aplicación:

Rendering a view:
ROOT .DS . views .DS . layout .DS . default .DS . header.php
ROOT .DS . components .DS . component .DS . views .DS . view . DS . vista.phtml
ROOT .DS . views .DS . layout .DS . default .DS . footer.php

To send information to views, assign variables in the controller as follows:
$this->_view->_variable = 'foo';

To receive information in views, read the variables as follows:
echo $this->_variable;
