after updating to 1.8 or 1.9 repeating listing of first set of subcategories in menu

[david042]

Hi,

I found, after updating from 1.7 to 1.8, that the code changed in app/code/core/Mage/Catalog/Block/Navigation.php

In 1.7 and 1.6 there was

public function getCurrentChildCategories() 
    {
        $layer = Mage::getSingleton('catalog/layer');
        $category   = $layer->getCurrentCategory();
        /* @var $category Mage_Catalog_Model_Category */
        $categories = $category->getChildrenCategories();
        $productCollection = Mage::getResourceModel('catalog/product_collection');
        $layer->prepareProductCollection($productCollection);
        $productCollection->addCountToCategories($categories);
        return $categories;
    }

Now with 1.8 there is

public function getCurrentChildCategories()
    {
        if (null === $this->_currentChildCategories) {
            $layer = Mage::getSingleton('catalog/layer');
            $category = $layer->getCurrentCategory();
            $this->_currentChildCategories = $category->getChildrenCategories();
            $productCollection = Mage::getResourceModel('catalog/product_collection');
            $layer->prepareProductCollection($productCollection);
            $productCollection->addCountToCategories($this->_currentChildCategories);
        }
        return $this->_currentChildCategories;
    }

This made it necessary to modify my code to null _currentChildCategories before calling the function.

<?php $this->_currentChildCategories = null;?>
<?php $_categories=$this->getCurrentChildCategories()?>
