I am currently trying to modify catalog/product/list/related.phtml, and I found out that it uses Mage_Catalog_Block_Product_List_Related.
$this->getItems()->getSize() to check the number of related products involve is correct. I verified that there is 1 related product owned by the current product. However, it says
0 in the result, and it would not display any related product, which does not make sense.
The block seems to work, but it does not display the related products although I verified that there is a related product. What should I do here?
