StatfulSnippet does not actually have session scope. It guarantees
that for the same request you get the same snippet instance. If for
some reason you still don't want a StatefulSnippet you can put your
results in a RequestVar, set the value when you process the form and
use it when render the page in binds.

Hi.
From my various readings, I believed that a single instance of a
snippet will be used for a particular request. I am trying to make use
of this in order to implement a search feature in my app. So I have a
template that looks like this:
lift:surround with=default at=content
h1Search/h1
lift:SearchSnippet.nameSearch form=POST
Name:nbsp;search:name/nbsp;nbsp;search:submit/
/lift:SearchSnippet.nameSearch
h1Results/h1
divlift:SearchSnippet.searchResultsfires:list
divresult:name//div
/fires:list/lift:SearchSnippet.searchResults/div
/lift:surround
And my snippet looks like this:
class SearchSnippet {
var results : List[Result] = List()
def nameSearch(xhtml : NodeSeq) : NodeSeq = {
var name =
def process() {
results = ... some stuff to get the results ...
}
bind(search, xhtml,
name - SHtml.text(name, name = _),
submit - SHtml.submit(Search, process))
}
def searchResults(xhtml : NodeSeq) : NodeSeq =
results.flatMap(f = bindResult(f)(chooseTemplate(results,
list, xhtml)))
def bindResult(result : Result)(xhtml : NodeSeq) =
bind(result, xhtml,
name - result.name)
}
What I expected is that when the form is submitted, an instance of
SearchSnippet will be created and 'results' will be populated. Then,
when the results sectionof the template is processed, the
'searchResults' method can bind the results. However, I never see any
results, and a bit of debugging suggests that different instances are
in play. Is this as expected?
I don't think I want a StatefulSnippet because that seems to have
session 'scope'.
What to do?
Regards,
Lance
