Difference between #4 and #5 of How to use a Widget as an Action Provider

##What is an Action Provider Widget?
As written on the [API
docs](http://www.yiiframework.com/doc/api/1.1/CWidget#actions-detail
"actions"): An Action Provider Widget is a widget that has declared
several actions by using its '**public static function actions()**'. After, a
Controller can easily import all its declared actions on its '**public function
actions()**'.

##Step 1: Create the Action Class
For the sake of the article we need to createcreating an
action named **getData** that is supposed to be shared among the
whole project and saved with the name **getData.php** on our
**protected/components/actions** folder.
~~~
[php]
class getData extends CAction{
    public function run(){
        echo 'HELLO WORLD';
    }
}
~~~
##Step 2: Configure the Widget
To transform a Widget into an action provider is quite easy (once you know of
course). The only thing we need to do is to set the static function
**actions()**. As you will see on the following code, we name the action as
**GetData** and that is the action that will be called in our route. We are
going to save the following widget in our **protected/components/** folder with
the name **testProvider.php**.
~~~
[php]
class testProvider extends CWidget{
    public static function actions(){
        return array(
           // naming the action and pointing to the location
           // where the external action class is
           'GetData'=>'application.components.actions.getData',
        );
    }
}
~~~
##Step 3: Configure the Controller
Finally we set our controller’s **actions()** function to point to our actions
provider.
~~~
[php]
// This function is in this example
// on SiteController
public function actions()
{
   return array(
      // test. is the prefix we are going to use on our URL
      // for all actions within the actionProvider class
      // we point to the location where the provider
      // is.
      'test.'=>'application.components.testProvider',
    );
}
~~~

All done, now we can call all the **actionProvider** actions as
**controllerID/actionPrefix.actionID**. Here is the example:

~~~
[php]
index.php?site/test.GetData
~~~

###Passing Parameters to Actions
As you all know, and already explained in the wiki [Actions Code Reuse with
CAction](http://www.yiiframework.com/wiki/170/actions-code-reuse-with-caction/
"Actions Code Reuse with CAction"), Actions are classes that extend
from CAction, that is, a CComponent. If we wish to pass parameters to the
actions that are within the provider, we have to do it this way when configuring
your controller (step 3) (Thanks to
[Attilio](http://www.yiiframework.com/user/25057/ "Attilio") for
pointing this out):
~~~
[php]
// This function is in this example
// on SiteController
public function actions()
{
   return array(
      // test. is the prefix we are going to use on our URL
      // for all actions within the actionProvider class
      // we point to the location where the provider
      // is.
      'test.'=>'application.components.testProvider',
               'getData'=>array(
                // property1 must be a public variable
                // on getData CAction class
                'property1'=>'value1',
                ),
    );
}
~~~
