I am seeing a weird issue with my Beerhouse implementation.

Occasionally when an end user places an order - the order will carry a user id like b8b50b29-836d-471d-9054-7658f6b31c09 which is an anonymous user id in the aspnet_users table.

it appears that some shopping carts are not being switched over and assigned from an anonymous user id to the actual logged in user.

I am not sure if the problem is with my code or with the browser the end user is using or even maybe the settings within the browser ( like not to accept cookies)

Any suggestions as to possible causes would be greatly appreciated.

Not sure what you mean, as the Order object has no UserID property.

The user who placed the order is stored in the AddedBy property. Is that possibly what you mean?

That is correct - I am sorry I wasn't clearer.

Every once in awhile I see an order with an 'added by' like '75a539b9-698d-4575-896f-e97c3f3e407c'

and issuing the following sql against my database returns a record

SELECT [ApplicationId]
,[UserId]
,[UserName]
,[LoweredUserName]
,[MobileAlias]
,[IsAnonymous]
,[LastActivityDate]
FROM [dbo].[aspnet_Users]
WHERE USERNAME='75a539b9-698d-4575-896f-e97c3f3e407c'

That is very odd. Just looking through the code of the original implementation, it doesn't seem like this is even possible, as the shopping cart cannot finish an order unless the current user is authenticated.

Perhaps you have altered your own implementation somehow?

If you are working from the English version of the book take a look at page 443. Otherwise, ensure you have modified the Profile_MigrateAnonymous event handler in the global.asax file to migrate the shopping cart from the anonymous user to the logged in user.
