I have founded that I'm unable to use a variable defined in the ApplicationController class inside a template when using renderAction() inside an action, but it's available when using the default action's template.

Sample code: when calling /port/listing the template shows correctly $users_online (5) and $another_var (1), if I call /port/inputs shows $another_var (2) value but it drops me a Notice : Undefined variable for $users_online.

Any clue? Thanks in advance.

Btw, sorry about my "usually long" posts but it's the only way to explain myself when the english level it's not enough ^_^.

application_controller.php

class ApplicationController extends AkActionController {
    var $users_online = 5;
    //......
}

port_controller.php

class PortController extends ApplicationController {
    var $layout = 'admin';
    function listing() {
         $this->another_var = "1";
    }
    function inputs() {
        $this->another_var = "2";
        $this->renderAction('listing');
    }
}

listing.tpl

<div><?= $users_online ?></div>
<div><?= $another_var ?></div>

Yuk! I've founded that I made a mistake that probably changes it all, the code I posted above works... (blush xD)

The problem comes when, with the same scenario, the variables are defined for ApplicationController inside an afterFilter-called function.

So application_controller.php would be:

class ApplicationController extends AkActionController {
//......
    function _construct() {
        $this->afterFilter('_getOnlineUsers');
    }

    function _getOnlineUsers() {
        $this->users_online = 5;
    }
}

The rest is exactly the same, and the behaviour is what I wrote before: When calling 'listing' action shows up $users_online, if I call 'inputs' action, it doesn't.
