Magento related products related and bottom recommended products upsell cannot repeat

This issue should take into account the related module and the Upsell module who first loaded the problem results prove that the content of the Upsell module first loaded (this loading by the way can be adjusted temporarily no research)

So first record Mage::register ("Upsell_used_product_ids", $all _product_ids); The related product module calls Mage::registry (' Upsell_used_product_ids ') to filter the products that already exist in the Upsell
