CakePHP: Components, redirect fail (On my part…)

class CounterComponent extends Component {
  var $components = array(
    'Session'
  );
 
  function i() {
    if ($this->Session->check('Counter.i')) {
      $i = ($this->Session->read('Counter.i') + 1);
 
    } else {
      $i = 0;
    }
 
    $this->Session->write('Counter.i', $i);
 
    return $i;
  }
 
  function clear() {
    $this->Session->delete('Counter.i');
  }
}

  function edit($id) {
    if (!empty($this->data)) {
      // process it
      $this->Customer->id = $id;
 
      $this->Customer->save($this->data);
 
      $this->redirect(array(
        'controller' => 'customers',
        'action' => 'view',

      ));

      ));
