Yikes! in that case, I wrote a whole application based on false assumption.
It says in the lift book
a StatefulSnippet is "ideal for small, conversational state, such as a form
that spans multiple pages"
If it spans multiple pages, doesn't this kind of imply the same instance in
the session?
Anyway thanks for this info. Any reason why a StatefulSnippet always has a
dispatch function and
a Stateless one, by default, has not?
to avoid RequestVar-s but keep state for current rendering pipeline in
