Magento – SUPEE-6788 – Call to a member function `isTypeAllowed()` on a non-object

errorsupee-6788

I have applied patch SUPEE-6788 but this breaks my store and generates an error:
Call to a member function isTypeAllowed() on a non-object in Mage/Core/Model/Email/Template/Filter.php

I have whitelisted all blocks and variables, but this problem still occurs.

I found out that replacing Mage/Core/Model/Email/Template/Filter.php with code from before the patch solves the problem.

I can't find out how to track down the problem and solve this.
Any suggestions?

If you check the Filter.php file after applying 6788 patch, you will find it is adding below bit of code.

if ($this->_permissionBlock->isTypeAllowed($blockParameters['type'])) {
   $type = $blockParameters['type'];
   $block = $layout->createBlock($type, null, $blockParameters);
}

This $this->_permissionBlock is object of Mage::getModel('admin/block'); model which is new settings added by this security patch. you can find this settings in admin.

Admin -> System -> Permission -> Blocks

Check if this settings are exist in your system. Check class Mage_Admin_Model_Block exist in your system or not.

Magento – Call to a member function getBackend() on a non-object

Use the following script to list product attributes with non-existant backend models:

umask(0);
require 'app/Mage.php';    
Mage::setIsDeveloperMode(true);
Mage::app('admin');

$entityType = Mage::getSingleton('eav/config')->getEntityType('catalog_product');
foreach ($entityType->getAttributeCollection() as $attribute) {
    if ($backendClass = $attribute->getBackendModel()) {
        try {
            class_exists(Mage::getConfig()->getModelClassName($backendClass), true);
        } catch (Exception $e) {
            echo "Not found the backend model {$backendClass} for product attribute {$attribute->getAttributeCode()}\n";
        }
    }
}

Category Collection Error – Fix Call to getId() on Non-Object

addCategoryFilter does not work with an integer parameter. It expects a Mage_Catalog_Model_Category or at least a Varien_Object.

So you have to do this:

$category = Mage::getModel('catalog/category')
         ->setStoreId(Mage::app()->getStore()->getId())
         ->load(71);
$collection->addCategoryFilter($category);

If you don't want to load the category object for performance reasons you can do this:

$obj = new Varien_Object();
$obj->setId(71);
$collection->addCategoryFilter($obj);

The down side of this second approach is that if the category with id 71 has is_anchor set to true then it won't be taken into consideration.
To overcome that use this:

$obj = new Varien_Object();
$obj->setId(71);
$obj->setIsAnchor(1);
$collection->addCategoryFilter($obj);

The down side of this third approach is the exact opposite of the second one. If the category is not an anchor it will be treated as an nachor category.
