title: Magento 1.4 Load By Category Not Working
body: <p>I have a Magento helper class I wrote that works wonderfully in 1.3.  However, we're working on a new install of 1.4 and filtering by category won't work for some reason.</p>
  
  <pre>
   function __construct()
   {
    Mage::app();
    $this->model = Mage::getModel('catalog/product');
    $this->collection = $this->model->getCollection();
    $this->collection->addAttributeToFilter('status', 1);//enabled
    $this->collection->addAttributeToSelect('*');
   }
  
   function filterByCategoryID($catID)
   {
    $this->collection->addCategoryFilter(Mage::getModel('catalog/category')->load($catID));
   }
  </pre>
  
  <p>I can't figure out why this isn't working in 1.4.  Has anyone else come into this issue?</p>
