That's what I thought. I checked and the code block is not getting
called.
val red = urlEncode(S.hostAndPath + (link("/jSearch", () => println("I
was called " + fn), NodeSeq.Empty) \ "@href").text)
println("redirect url: " + urlDecode(red))
The second print statement does print a valid looking url:
redirect url: http://localhost:8080/jSearch?F1169402556414Y5H=_
However the "I was called " println block is never called.

It does actually. Programming in Scala pg. 520

Yes, I thought about doing that. I went thought the source and found
that method but I am not really sure what to put there. All I want to
to is return to the third form with access to data from the previous
two forms. The third form comes up but the data from the previous two
is gone.
At this point I created a new git branch that used DispatchSnippets
and SessionVars and in works so I need to move on.
Thanks again for your help.
