OrderTemplate.Save problem |
|
|
I use MSCS2002 + SP3 + FP1.
I try to use OrderTemplate class to store "wish list" for a user -
something like shopping cart but without quantities and checkout (it's
like favourites in internet explorer, used to "bookmark" some products).
I have created the WishList class attached.
I use the following code to add product to wish list:
wishList.AddProduct (this.ProductID);
wishList.Save();
Everything is ok, in debugger I can see that the product is added.
But on the next postback of the same aspx page it is empty! It
seems like it was not saved successfully.
Please, advice.

Some details. |

After debugging it for a while, I found out that even the order
form is not saved - on next postback when OrderTemplate is retrieved it
contains no order forms.
Please, advice.
