Hi folks. 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.

 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));
 }

I can't figure out why this isn't working in 1.4. Has anyone else come into this issue?
