How can I extend/override admin create order controller?

Question

I am trying to override adminhtml_sales_order_create controller. I have created a small module app/code/local/PA/Sales/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <PA_Sales>
            <version>0.1</version>
        </PA_Sales>
    </modules>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <sales before="Mage_Adminhtml">PA_Sales_Adminhtml</sales> 
                    </modules>
               </args>
            </adminhtml>
        </routers>
    </admin>
</config>

and created controller file as

app/code/local/PA/Sales/controllers/Adminhtml/CreateorderController.php

<?php
require_once 'Mage/Adminhtml/controllers/Sales/Order/CreateController.php';
    class PA_Sales_Adminhtml_CreateorderController extends Mage_Adminhtml_Sales_Order_CreateController
    {
         public function indexAction()
        {
                 echo "something";exit;
        }
    }

I am unable to override this controller, where did I go wrong?

Answer 1

you need to put your controller in app/code/local/PA/Sales/controllers/Adminhtml/Sales/Order/CreateorderController.php and name your class accordingly.
As a general rule, when rewriting a controller from Mage/Adminhtml/Some/Controller/HereController.php your new path should be Namespace/Module/controllers/Adminhtml/Some/Controller/HereController.php.
So what comes after Adminhtml in the original controller should be kept after Adminhtml in your custom controller.
