Start to play with lift now. My first issue is a simple guest book.
There are several guest notes in the guest book list page. I want to
display a reply form under each guest note. But I don't know how to
bind the reply form to its note record. How can I do with this? I'm
using Mapper now.
Below is the snippet and list page.
Thanks for your reply and time.
PS. As I was blocked from the google groups. I'm sorry to say that
maybe I cannot reply to your comment in time. Thanks again in advance.
