Still have to do StatefulSnippet, but the example of passing info in a
RequestVar (listing 3.24) is updated to show a redirectTo example as well.

I'll add in an example for StatefulSnippet. We have one already in
PocketChange, so I just need to copy the code listing in. You should be able
to mix the two as you see fit.

Thanks, Derek. I read the updated PDF version of the book on "The
Lift Book" group. I think it looks good. I think an example with
redirectTo may be better than link. Also, personally, I'm not sure if

the two. I updated my co
OK, I just added some more explanation on passing state between snippets to
section 3.15 in the book. I just uploaded a new PDF. When you have a chance
could you look at it and let me know if that makes sense? Also, I wasn't
sure if this should be a separate section ("Passing Data Between Snippets"
A RequestVar is only "live" for the duration of the request, and a
redirectTo ends up sending a 307 temp redirect to the browser, which results
in a new request. S.redirectTo does have an overload that allows you to pass
a function that will be called when the redirected request is handled. Some

Thanks, Tim. I worked around that issue.
I would still like to know whether or not it's possible have
RequestVars carry over to the redirected page. I'm attaching a
modified demo. If I use just a var, it will maintain the state. If I
use RequestVar, it won't transfer the state.
Well.. I coul
Its talking about Hibernate session, not lift session. Perhaps you have a
detached model or something your trying to work on?

Thanks, Sergey. When I removed the reuqestVar, changing these two
lines
object productVar extends RequestVar(new Product())
def selectedProduct = productVar.is
to
var selectedProduct = new Product()
It worked. Now I'm having a Hibernate problem.

Could you attach a sample code which doesn't work?

I have "changed class Products {" to read "class Products extends

Instead of S.redirectTo, I now have this.redirectTo and it still
doesn't seem to be saving the state.

OK, first, your snippet class needs to extend StatefulSnippet. Then you need
to define the dispatch partial function to tell it which snippet goes to
which function, and then you need to use StatefulSnippet.link and
StatefulSnippet.redirectTo instead of SHtml.link and S.redirectTo,
respectievly.

I guess it would help to mention that is on
index.html and is on select.html.
