I had a request for changing the sort order of the wishlist to be by the product code instead of the order they were entered. The idea is that it will be more useful to have the products grouped by vendor code. I thought it was a good idea and have made the change.
In the process of testing there were a few users wishlists that were cleared due to an unexpected behavior in the code caused by an unnecessary parameter being passed. I apologize for that and in the future there shouldn't be any issues with the wish list clearing itself.
