AclExtras Warning Error
===

In cakephp 2 book -> Acl Tutorial -> Part 2.
[Actual Link][1]

I am executing the command `./Console/cake AclExtras.AclExtras aco_sync` and get a warning error:

Warning Error: Argument 1 passed to Component::startup() must be an instance of Controller, null given, called in /opt/lampp/htdocs/acl/app/Plugin/AclExtras/Console/Command/AclExtrasShell.php on line 80 and defined in [/opt/lampp/htdocs/acl/lib/Cake/Controller/Component.php, line 119]

The acos table gets populated with NULL in Model Fields and NULL in all fields of Foreign Key. How can I fix that error?
