So I guess my question is how prevent it from doing that and still
pass a User object to the RequestVar I tried a RequestVar[User] but no
bueno
below is the snippet code for registering a user
user.password = passwordHashed
user.activationCode = activationCode
user.userProfile.user = user
user.userPreferences.user = user
Model.mergeAndFlush(user)
MailUtils.mailConfirmationLetter(user)
S.redirectTo(thank_you, () = { println(user); userVar(user);}
In the mean time I'm going to just extract the email and fullname from
the user and pass it as a request param
user.password = passwordHashed
user.activationCode = activationCode
user.userProfile.user = user
user.userPreferences.user = user
Model.mergeAndFlush(user)
MailUtils.mailConfirmationLetter(user)
val email = user.email
val fullName = user.userProfile.fullName
println(email + email)
S.redirectTo(thank_you, () = {S.set(email, email); S.set
(fullName, fullName);})
Thanks for helping out

[Lift] Re: Using Stateful Snippets
It seems that you are correct. My user object is a JPA entity and when
it enters the closure it has a different identityHash 10749831 vs.
21737589. This will probably be one of many issues that I will have
to deal with if I'm going to continue with JPA? It's like the
entityManager loses reference to the entity object I persisted to the
db. That's no good. I'm starting this project from scratch and have
a java background is it easier to just pick up with Scala's persistent
architecture then continue with these little bumps in the road.

And user is not a RequestVar, correct? So this is not a RequestVar problem
then?
What is user? A JPA entity? Could this be a JPA issue?
If you like you can use System.identityHashcode to demonstrate that the same
user instance is losing its data.

[Lift] onkeypress
Is there a SHtml.ajaxText equivalent that will perfrom an ajax call
when the onkeyPress is invoked? I want the ability to query the db to
see if a particular username is available or unavailable each time
the user types in a letter within the input field. I can only get
this accomplished on blur.
I tried the following:
SHtml.text(user.username, user.username = _) % (onkeyPress -
ajaxCall(JE.JsRaw($('#username').attr('value')), s =
isUsernameAvailable(s))) }
but no bueno
