Hello,
I have a simple use case where there is a 2 page form wizard then a
redirect to a third party ( for some external validation ) which
redirects back to a third and final page of the wizard.
I know I could just use snippets and SessionVars to manage this but I
have been using StatefullSnippets and would like to try to solve this
problem rather than accept failure and use another method.
I pass the url for the third page to the third party to redirect to
when their work is done. The problem is the snippet state is lost
after the redirect. I have tried many different things and it seems
like something like this should work.
// in the processing done before redirect to third party.
// assemble the return path url.
class Wizard extends StatefulSnippet with Logger {
....
def doRedirect = {
val returnPath = urlEncode(S.hostAndPath + ( link("/lastPage", () =>
redirectTo("/lastPage"), NodeSeq.Empty) \ "@href).text)
redirectTo( third_party_url +"?return=" + returnPath)
}
}
This does generate a return path like "http://localhost:8080/lastPage?
F1151306194165AHF=_" , however all state is gone after the third party
redirects back to the site, however if I don't redirect to the third
party and instead redirect the "val returnPath" I construct directly,
state is maintained.
Is it possible to resume my StatefulSnippet? Or shall I just use
something else?
Thanks to all who read and or respond.
-Andy
