Can you not add the code in your display_cart view?
Just put something like <%= visual_effect :highlight,
'cart_item_'[EMAIL PROTECTED] %> in the display_cart template (maybe
add some logic to only perform the effect if it's a xhr request) and
since rendering of that view is essentially going to happen when the
request is complete it should accomplish the same thing no?
Just my quick thoughts. Maybe I'm missing something. :)
