[Lift] Scala Lift Off East
I'm waiting for a ride to Union Station, so I thought I'd use this time to discuss some of the questions and concerns I heard about lift at the recent Scala Lift Off East. Personally, I did not attend any of the lift sessions, so I'm definitely leaving a lot out. I like lift and its community, so I want to make sure these points get mentioned. 1. There were a handful of lift sessions called, but no active committers at the unconference to go into depth about a given topic. That could be why most of the sessions were about using lift in particular environments, such as clustered and under GAE. 2. With the above said, much praise did go out to the lift community for their responsiveness to develop feature requests and fix bugs. 3. There was interest -- myself included -- to learn more about Record. 4. I heard a few discussions concerning the use of Sessions. They wanted to know how this impacted scalability. 5. Just an observation: I was surprised to learn that many people at the conference had never used maven before. 6. Users discussed that lift was very fast to develop in. One group there mentioned that they used lift to replace an existing PHP app. Another user held a session on how his company used lift to create its website in under 90 days. -- I hope I got that right. --Bryan Sent from my iPhone --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Don't shoot the non-XML messenger ...
Hi Aule,
I am still looking to see if I over-looked somewhere on the web where
there is a 1.0.2 Boot.scala
1) showing unambiguously how to flip the default Content-Type
2) and having, in fact, the intended effect
as I now know from a few trials over a few hours that this is not as
simple as some web posts present.
I have not had a need for this, so I had to search some web posts to
find the answer. Quckly, I found the following snippet:
LiftRules.determineContentType = {
case _ = text/curl
}
I have not verified this, so please let us know if it does not help.
Were it trivial, I had not mocked a framework, and you, Mr. Pollock,
had not raged.
From my readings, Mr. Pollak has yet to show any rage.

I managed to fix the id problem, I needed the Hibernate specific class

@Entity

strategy=increment}
�...@generatedvalue{val strategy = GenerationType.SEQUENCE, val

var id : Long = _

var ordering : Int = _
�...@column{val unique = true, val nullable = false}
var name : String =
�...@manytoone{val optional = false}
var storyBoard : StoryBoard = _
}
However, now I get an org.hibernate.PropertyValueException: not-null
property references a null or transient value:
model.Scene.storyBoard :-s I tried a lot of things already, the
corresponding StoryBoard is saved and not null, so I guess it has to
be transient. Merging the StoryBoard however still gives the same
error..
I tried to get JPA and Lift working together in the same way as in the
JPADemo example.. Is it the use of MySql which prevents the example
from working for me?

That's not accurate, at least with Hibernate. By putting the annotations

forces Hibernate into a field-based persistence model and not a

you
need a sequence set up for the auto identity model. What database are

I just made the autocomplete a Lift widget so it does not exist

- For Ajax autocomplete
AutoComplete(, (current, limit) = {
println(current = + current)
(1 to limit).map(v = Value_ + v)
}, s = println(submit + s))
- For pre-provided options list
AutoComplete.autocompleteObj(/*same params as bfore*/)
This may break your app but I think it is very easy to update it.
I also fixed some bugs:
1. It didn;t work if the container cookies were turned off
2. hovering on the options list did not work on Ubuntu FF3 at least
due to a capitalizated LI equality test.

[Lift] Re: How to handle refresh with S.redirectTo with state?
Thanks for the reply, Marius.
I just saw your reply and am not sure I fully grasp how this is safe.
What if request A comes in and sets com.bryan.myproject.locationQuery
and starts working on processing the rest of the request. In the
meantime, request B comes in and sets
com.bryan.myproject.locationQuery. Now request A finishes processing
the request, upon which it has to read in
com.bryan.myproject.locationQuery. Wouldn't request A now be reading
in com.bryan.myproject.locationQuery set by request B?
Or have I mistaken how objects work and how requests are handled in
lift?

processed RequestVar's. This works fine until I refresh the page,
because in these functions I call .open_! on some now Empty
RequestVar's. It is simple enough to show Text() when the box is
not Full, but now I have a problem with the page not showing useful
data.
What are some suggestions for handling this? Should I just add code
to each of my many snippet functions to redirect to / when the
RequestVar's are empty?
Thanks,
Bryan

[Lift] Re: scalar queries in Lift/JPA
I've never tried this on a scalar query, but a constructor expression
example should be something like this:
select new com.chas.values.AnswerCount(t.answer, count(distinct
answer)) from ...
class AnswerCount(answer: String, count: Long) {
private def nullToOption[T](v: T) = v match { case null = None case
_ = Some(v) }
def getAnswer = nullToOption(answer)
def getCount = nullToOption(count)
}
object AnswerCount {
def unapply(ac: AnswerCount): Option[(Option[String], Option[Long])]
= {
Some(ac.getAnswer, ac.getCount)
}
}

I have this query:

order by t.answer
but how do I call it? I normally do:
Model.createNamedQuery[...](findVoteCountAnswersByPoll,

But what is the type? And how do I get the results back out?
I know I did this once before somewhere, but I can't remember

[Lift] JPA Run Modes

[Lift] Conversation Context
Does lift offer conversation contexts? If so, could someone provide me with an example. I am not sure if conversation context is the proper term, but I am using this term as it is used by JBoss Seam. A partial description would be an approach that allows state to be scoped to a unit of work and automatically handles memory cleanup when a conversation is no longer in use. This would allow users to work in multiple tabs. Keeping the back button working during this process would be a *huge* plus.

That type of Wizard would be nice, though I am not a big fan of XML. Thank you for your willingness to come up with a solution, but I don't have a specific need for it right now.

[Lift] Re: Image Submit Buttons fail to Submit (in IE)
It would be nice to have some control over this. I work on a site where we forward users to the iPhone version of the site when they access / and their user agent matches the iPhone (or iPod Touch) user agent. But, we also provide them with a link to view the full version of the site. This is just something to consider. We handle the full version switch through some additional paths we have setup, but I've seen cookie- based implementations of this as well. --Bryan On Sep 26, 7:40 am, Marius [EMAIL PROTECTED] wrote: Very true Viktor.

[Lift] Comet and Flot
I am interested in adding some (almost) real-time charts to a project of mine. I have a couple of questions, though. 1) Is there documentation on lift's server and client implementation of comet available online? 2) Are there any reasons why dojo's comet client wasn't considered? 3) I see that there is a flot widget that will be integrated into lift soon. What benefits do these widgets offer over a normal JavaScript implementation? 4) I have an immutable Map of data that I need to push to the JQuery chart. Where should I begin? Do I send this in JSON format? A lot of questions, I know! p.s. I am loving lift so far. Great work. The CometActor tutorial was very useful as well.
