Controller action:

	function view($username) {
		if ($username != NULL) {
			if ($this->Session->check('User')) {
				$this->pageTitle .= 'View your profile'; // $pageTitle's beginning defined in app_controller.php
				$this->User->username = $username;
				$this->set('user', $this->User->read());
			} else {
				$this->User->username = $username;
				$this->pageTitle .= 'Account Information › ' . $username; // $pageTitle's beginning defined in app_controller.php
				$this->set('user', $this->User->read());
			}
		} else {
			$this->redirect('/users/list');
		}
	}


View (as bare as possible, just to check functionality):

<?php echo $user['User']['first_name']; ?>
