[Seaside] examples question

[Sean Allen]

is the back button supposed to work in the sushi store example?

i'm trying to use the examples to learn from and I'm not sure if the  
back button after add to cart should remove items from cart ( which it  
doesnt ) and that is just a bug or if nothing is done with the back  
button ( i've spent about 1 day w/ seaside, so forgive what is  
probably a very dumb question. )
