CS 2k2 Retal Site Exception

Hi Branimir,

This could potentially be due to your adding a non-serializable object as a
weakly-typed property (String indexer) on one of the Basket child classes.

For e.g. if you have something like:
myCart.OrderForms[0].LineItems[0]["myBusinessObject"] =
myBusinessLogicObjectInstance;

where the variable myBusinessLogicObjectInstance is not serializable.

Thanks,

Hi there,

I have a problem with the default installation of CS2k2's Retail solution
site. When I open the solution, build it, and then add an item to my cart
I
recieve the following exception:

Description: An unhandled exception occurred during the execution of the

about
the error and where it originated in the code.

We're using XP SP2 and CS2k2 with SP2 and FP1.
Any ideas about the cause of the exception and how to avoid it?
