Get Id of product being removed from Product Compare

Question

I am trying to get the id of the product being removed from the Compare Products list. I have successfullye caught the event catalog_product_compare_remove_product but when i try to the the id of the product using $productId = $observer->getEvent()->getProduct()->getId(); all I get is a counter that increases with one every time i delete a product from the Compare Products list.

Doing the same when catching the event catalog_product_compare_add_product returns the product ID as expected.

So, my question is: What is this counter and how can i get the actual prouduct Id

Answer 1

Try with

$productId = $observer->getEvent()->getProduct()->getProductId();

In this case the entity passed to the observer is not an instance of Mage_Catalog_Model_Product. It is an instance of Mage_Catalog_Model_Product_Compare_Item.
When calling getId on that you get the increment id of the item to compare from the table catalog_compare_item.
