We're about to launch a site with about 1400 items in a couple of hundred categories. On our Category Listing pages, the Categories are sorted by product_name while the Products are sorted by product_code. The listing displays work precisely as we expect, but when we view an individual Product, the Next/Previous buttons at the top of the layout don't always follow the product_code sort order. Since the Products were inserted using a spreadsheet, the product_id values are mostly sequential as well, so it isn't sorting by that method, either. Whatever sequence they are following, it seems to be consistent between sessions. This mismatch doesn't happen for all the categories, but so far, we can't find a pattern.
The default Product ordering settings are set for product_code/ascending and the Hikashop default menu entry is set that way as well. All of the menu items have been told to inherit these settings. There are three top-level Category Listing pages - Cast Stone, Plaster, and GFRC Resin, and there are two submenu Category Listings under Mantels - Cast Stone Mantels and Plaster Mantels. While these are not the only Categories that display this behavior, they have done it consistently.
Any suggestions?
