Failed to get more category items

[Able-fans]

I got a category includes 49 products and no sub-categories. There is nothing showing for more category item tab in product page. Via debug, finding there is a place to cast catalogNode to catalogProductNode fails. Is anyone know why the 49 products nodes can not be cast to catalogProductNode?

Code: Select all

 private IList<CatalogNode> GetProductNodes(int categoryId)
        {

            //GET ALL NODES IN THE CATEGORY
            IList<CatalogNode> allNodes = CatalogDataSource.LoadForCategory(categoryId, true, "OrderBy");
            //EXTRACT THE PRODUCT NODES
            IList<CatalogNode> productNodes = new List<CatalogNode>();
            foreach (CatalogNode node in allNodes)
            {
                //ATTEMPT TO CAST TO PRODUCT
                CatalogProductNode p = node as CatalogProductNode;
                if (p != null) productNodes.Add(p);
            }
            return productNodes;


        }

This is a bug in Gold and Able patched it like this:
replace:

Code:
//ATTEMPT TO CAST TO PRODUCT
CatalogProductNode p = node as CatalogProductNode;
if (p != null) productNodes.Add(p);


with:

Code:
// FILTER PRODUCT NODES
if (node.CatalogNodeType == CatalogNodeType.Product && node.ChildObject != null)
{
productNodes.Add(node);
}
