Hi
I think you need to add the error resource to the Acl and allow full access to
error controller.
Thanks

The plugin preDispatch() is invoked earlier than the helper preDispatch(). The
order kinda looks like this:
plugins.routeStartup()
router.route()
plugins.routeShutdown()
plugins.dispatchLoopStartup()
[loop]
plugins.preDispatch()
[if controller exists]
controller.init()
helpers.preDispatch()
controller.preDispatch()
controller.action()
controller.postDispatch()
helpers.postDispatch()
[/if]
plugins.postDispatch()
[/loop while request.isDispatched is false]
plugins.dispatchLoopShutdown()
The problem with the ACL plugin is that the checking is done before the
dispatcher could determine if the controller class being requested exists.
There are a couple of ways to solve this:
- pull the dispatcher object from the front controller, test
$dispatcher->isDispatchable($request) in your plugin and act accordingly.
Basically, you duplicate the logic in the dispatcher dispatch().
- defer the checking until after the controller has been instantiated but
before the action.
You have three places to do the latter: controller init(), helper preDispatch()
and controller preDispatch(). Two of those require you to extend a different
base controller. I prefer doing it in a helper since I might want to have other
logic in some of my controller hooks so I don't have to remember calling
parent::init() or preDispatch().

Why an action helper, why not a plugin?
I'd like to know as well. Is an action helper more appropriate for the case
I described, or should an action helper always be used for Authorization (
Zend_Acl anyways)?
In genral, what is the difference beteween front controller plugins and
action helpers. When would you use one instead of the other?
To give Vladas a short answer based on my case, the front controller plugin
did not provide the functionality I wanted. An action helper did.
Thanks a lot,

Use an action helper with a preDispatch() hook, and register it in your
bootstrap. :)
