I think that Price Lists are not working as expected in CRM 4.0.

Here's a scenario. I have two price lists defined, Retail and Wholesale. I add some products and create price list items for them on the retail list. I add some other products and add them to the wholesale price list. But I don't set the default price list for any products.

My understanding (and I think CRM help supports this) is that the default price list is optional and that provided a product has a price list item for a price list that matches the price list of an opportunity or an order etc, the product can be added to a record.

So, if I have an order with a retail price list I would expect to be able to add products that have price list items on the retail price list.

What I find, in practice, is that I can't add any products to opportunities etc unless I set a Default Price List - which is weird because this is not a mandatory field.

And when I set a Default Price List of say retail, I find that products that only have retail price list items can be added to an opportunity with a wholesale price list. I sort of understand this, because I guess that is what the default price list is for. But I don't understand why products that don't have a default price list can't be used.
