Custom layout based on the attribute set not working

Question

I've followed this tutorial to add attribute set specific product page layout updates, but it doesn't work.

Here's my code:

file: app\code\local\Magebase\AttributeSetHandle\etc\config.xml

Code:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Magebase_AttributeSetHandle>
            <version>0.1.0</version>
        </Magebase_AttributeSetHandle>
    </modules>
    <global>
        <events>
            <controller_action_layout_load_before>
                <observers>
                    <attributesethandle>
                        <class>Magebase_AttributeSetHandle_Model_Observer</class>
                        <method>addAttributeSetHandle</method>
                    </attributesethandle>
                </observers>
            </controller_action_layout_load_before>
        </events>
    </global>
</config>

File: app\code\local\Magebase\AttributeSetHandle\Model\Observer.php

CODE:

<?php
class Magebase_AttributeSetHandle_Model_Observer
{
    /**
     * Converts attribute set name of current product to nice name ([a-z0-9_]+).
     * Adds layout handle PRODUCT_ATTRIBUTE_SET_<attribute_set_nicename> after
     * PRODUCT_TYPE_<product_type_id> handle
     *
     * Event: controller_action_layout_load_before
     *
     * @param Varien_Event_Observer $observer
     */
    public function addAttributeSetHandle(Varien_Event_Observer $observer)
    {
        $product = Mage::registry('current_product');

        /**
         * Return if it is not product page
         */
        if (!($product instanceof Mage_Catalog_Model_Product)) {
            return;
        }

        $attributeSet = Mage::getModel('eav/entity_attribute_set')->load($product->getAttributeSetId());
        /**
         * Convert attribute set name to alphanumeric + underscore string
         */
        $niceName = str_replace('-', '_', $product->formatUrlKey($attributeSet->getAttributeSetName()));

        /* @var $update Mage_Core_Model_Layout_Update */
        $update = $observer->getEvent()->getLayout()->getUpdate();
        $handles = $update->getHandles(); // Store all handles in a variable
        $update->resetHandles(); // Remove all handles

        /**
         * Rearrange layout handles to ensure PRODUCT_<product_id>
         * handle is added last
         */
        foreach ($handles as $handle) {
            $update->addHandle($handle);
            if ($handle == 'PRODUCT_TYPE_' . $product->getTypeId()) {
                $update->addHandle('PRODUCT_ATTRIBUTE_SET_' . $niceName);
            }
        }
    }
}

In the local.xml inside the <layout></layout> i've added:

<PRODUCT_ATTRIBUTE_SET_Informatica>
    <reference name="product.info">
      <action method="setTemplate"><template>catalog/product/view-informatica.phtml</template></action>
    </reference>
</PRODUCT_ATTRIBUTE_SET_Informatica>

My attribute set is named Informatica and the customized view.phtml is located in design/frontend/[my-custom-tample]/default/template/catalog/product

What am I missing here?

Please help :)

Thanks guys,

Hi first need debug your current page handler by below code:

Zend_Debug::dump(Mage::app()->getLayout()->getUpdate()->getHandles());

I have modify code and add the handler only for product view page

<?php
class Magebase_AttributeSetHandle_Model_Observer
{
    public function addAttributeSetHandle(Varien_Event_Observer $observer)
    {
        if($observer->getEvent()->getAction()->getFullActionName()=='catalog_product_view'){
            $product = Mage::registry('current_product');
            if($product):
            $layout = $observer->getEvent()->getLayout();
            $attributeSet = Mage::getModel('eav/entity_attribute_set')->load($product->getAttributeSetId());
            $handle = str_replace('-', '_', $product->formatUrlKey($attributeSet->getAttributeSetName()));

            $layout->getUpdate()->addHandle('PRODUCT_ATTRIBUTE_SET_'.$handle);
            // check all Handler 
            //Zend_Debug::dump($layout->getUpdate()->getHandles());
            endif;
        }
        return ;
    }
}
