For those of us spoiled by the wealth of learning material on Rails, and to a lesser degree Django and web2py, all I can say is: 'Lift is a new framework, and a sophisticated one at that, which uses a new language derived from a convoluted one, and is at a relatively early stage of development, so therefore the designers are forging ahead to completion of the foundation, and thus there are few who can devote the time to creating the documentation we newcomers need.' My post on the book group defined the three classes of useful documents to be the Guidebook, the Encyclopedia, and the Cookbook. My role for the wiki is to hold Cookbook recipes which answer the most common 'how to' questions we encounter when building a website. In my personal learning quest, I am extending the 'ToDo' app by adding pieces of functionality, like many-to-many tagging, date manipulation, deletion, an admin interface, etc. As I come across solutions or questions, I post those on the group in order to help others and to get improvements and refinements from the members. David is right... Lift and Scala together are taking web applications to a whole new level of performance, so naturally it will take a little time to make things happen.

In an ideal world is it supposed to be the main repository of lift knowledge, or just another documentation source? I personally feel that having one repository of knowledge is much more noob friendly. Currently new members have to navigate through started guides, books, e-mail threads, scala docs, and personal blogs to find relative information. Though the get started guided and book provide a good introduction, it's hard to progress from novice to intermediate with these fragmented resources.

[Lift] Re: Snippets and Requests
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?

Lance

Hi,
For most apps cannonicalization is not really necessary as the
character stream for form-url-encoded is UTF-8 by default as Lift uses
UTF-8 by default. Oh and the conversion from URL encoding to plain
UTF-8 content is really done by container and when we get the params
from the request object they are already well formed. Now if we're
talking about a higher level of validation that's a different story
and IMO this is an application aspect and not much a framework one.
And Lift does URL Decoding of the paths before presenting them as the Req()
object.
More broadly, Lift should provide all the features of ESAPI out of the box.
If there are particular things that ESAPI offers that Lift doesn't, please
flag them and we'll add them.
I did a bunch of years as VPE and CTO at a web app security company. In
general, I've worked to make sure that Lift has security baked in and that
the developer has to work to make the app insecure, rather than vice versa.
If I missed a spot, Lift will be enhanced to make sure it does have
security baked in.
From my perspective Lift is secure, much more so than other frameworks I've
used. The current set of Lift apps, that I've helped develop, have survived
outsourced penetration testing without requiring any modifications at all.
Great!
I'm not a security expert, but I am being asked to consider ESAPI features.
From my limited understanding, the UTF-8 encoding is fine and Lift protects
the response from displaying any scripts or html that might have
inadvertently been added to the database. The problem is more what is being
validated and how its being validated. I don't buy Marius's claim that this
is somehow a higer order validation that is an application concern rather
than a framework one. The internet has all the insecurities it has, because
security has been left to the application developer.
The eligibility criteria from a web-string to be converted to String
object may differ greatly from application to application. This is why
so fat I disagree with you. In some contexts receiving scriptalert
('XSS')/script string is what application wants. Sometimes it is
not. Besides lift already protects us from XSS in great extent.
As far a I can see, one problem lies when a string is obtained from the web
page and instanciated into a String object. For instance, if it comes in as
scriptalert('XSS')/script, then its probably not what you want. Why
does it matter if something like this gets stored in your database - perhaps
because it's one part of your security. In addition if it comes in doubly
encoded as
%253Cscript%253Ealert('XSS')%253C%252Fscript%253E
then its probably also not what you want.
1) To stop double encoding, ESAPI suggests that you use cannonicalization to
convert the strings to a similar format before validation.
2) After, the input has been cannonicalized, ESAPI suggests that the input
should be validated against a whitelist of allowed charaters.
Now, I can't see that 1 or 2 is necessary if you are creating a number from
the input, but perhaps it should be, if you are creating a ordinary String
object. I also am not sure how much work would be involved in using a
whitelist in a location aware multilingual way, but perhaps it could be done
as a default.
I have nothing against ESAPI but as far as I'm concerned more
compelling and concrete use cases are needed for it to be incorporated
into the framework. As David said if there is a security hole
somewhere we're keen to know about it and fix it immediately.

Marius

You know, for now I'm playing with little examples, trying to modify the Pocket Change App of Lift book, this kind of things. And I have to say that a lot of my try are not successful. In T5, when something goes wrong, T5 takes me by the hand, show me the piece of template where the error happens, the faulty code, and give me advices on how to correct the problem. Moreover, T5 default behaviour is to fail early, so that less bad code is waiting for users to discover it - developers get big exceptions that they can't honestly ignore. There is (an really old) example of T5 error reporting here:http://tapestryjava.blogspot.com/2007/09/itch-scratching-even-better-...

There is an other example of enhanced error reporting, this time in the console:http://tapestryjava.blogspot.com/2008/12/exception-reporting-why.html So, what the goal of the mail ? Well, just to bring the attention of core team on how it's important and great to have good feedback from the framework (error reporting, early failure) and I do believe that T5 is state of the art in that domain...

[Lift] Re: So where is that OAuth?
On Jun 22, 3:25 am, DFectuoso santiago1...@gmail.com wrote: Well i went ahead and learn a lot from the lift-openId implementation and understand what I would need to do have lift-OAuth working It seems like i could do two things: 1) Get a OAuth java library that allows me to post, get, login and logout then create a OAuth.scala file where i create a trait of the OAuth Handler that would access to this methods, then create a object that extends from that trait; Then create a OAuthProtoUser.scala where I would have a trait for the MetaOAuthProtoUser with the Xhtml for login, override the menus that i would not use and perform the login and logout of the user as well as the post and get methods. Finally create a trait for the OAuthProtoUser that would allow me to store information about the user. Besides Proto stuff we'd need an abstraction over OAuth artifacts. Essentially a wrapper over their Java library. 2) Go ahead and have the login,logout, post and get methods on the OAuth.scala actually do the logic to get the tokens without a java library, this would mean creating some way of signing a url and body to post and get stuff from the request, access and user-auth Token Url or an url in the service. I have absolutely no experience with scala, java or lift but I really want to get some(by doing this type of stuff). So what do you think is better(for me to learn, for lift and for you). I think it would be a good exercise. Once you're done with it we could probably review it and maybe it'll get its way into Lift if some committer doesn't implement it in the mean time, but regardless would be a good exercise for you. Also, what part of this abstraction(and how) is the one to set the consumer_key, secret_key and the request urls? In OAuth world consumer secret and consumer key are somehow invariants as they impersonate a trusted service. So I would put them into a Scala object where user can just set these quantities from Boot. Finally; a uber noob question, what is the equivalent of curl(php) or urllib/urlopen(python) that i would use in the second option to actually make the http request to ther other site? I think its a servlet but some trivial example on this would really help me =) You can just use HttpUrlConnection, or Apache Http client.

No, in fact I took as an assumption the thread-safety of request/response (and I saw some thread local call in the lift code), but it was to be sure :) We use thread locals quite a bit for request life cycle state management. i.e. in S object, RequestVar etc. It is a concise model of scoping state.

Finding example apps to study and learn by is seemingly very difficult to do. Are there any out there? If so where? For new user, learning by examples is extremely important. I think a lot of new users will be turned off if it's difficult to find some example applications to study to learn from.

On Jun 29, 1:13 pm, Timothy Perrett timo...@getintheloop.eu wrote: Steven, Welcome to lift. Lift doesn't use the JSESSIONID in the URL... that is, lift does not require it (at least this is my understanding, if im wrong please correct me someone) - so you should have no problems with the requests being re-written. Actaully Lift is no different then a regular JEE web app. If you turn off cookies from the container you'll witness URL rewriting and JSESSIONID will be part of the URL. Regarding the GC stuff, it was added to improve memory usage of applications that run over a long period and to keep the heap size down. Marius or DPP would probably be able to give you more specifics but I think if your users are moving from page to page and you can cope with a slightly larger heap size then it shouldn't be too much of a problem. We did after all do without the GC stuff for quite sometime as it was only added recently. Essentially Lift GC is about de-referencing unseen bound functions if a certain period of time exceeds. There is a lightweight heart beat mechanism where Ajax requests are sent to keep functions alive. Of course bound function are associated with a generated page-id.

I'd like to write a Facebook application, both because I need one, and so I can learn more about Lift and Scala. I do have a few questions though, and I haven't been able to find answers in the documentation or mailing list. The first is about cookies and state. Facebook canvas applications return pages which are re-written by the Facebook servers, so the JSESSIONID cookie will not be present. As I understand it, that means I'll need to manage state myself. I was therefore thinking about returning pages from LiftRules.statelessDispatchTable (as described in the Lift book, 3.13). The problem here is that I'd need to return a LiftResponse directly, and wouldn't be able to use most of the Lift infrastructure. Is this the right way to do things? Is there some other way to suppress cookies and/or use Lift without them in the Facebook application context? My second question is also because Facebook suppresses Javascript when it processes web pages written in FBML. This means that the client-side code to do garbage collection of widgets won't run. I can disable the insertion using LiftRules.enableLiftGC, but will this trigger other problems? Finally, is there example code available for lift-facebook? It's great that Lift supports Facebook, but other than a small mention in the Lift book, I haven't been able to find any documentation. Some example code would be very useful in getting started. Is there any available?

[Lift] Re: can a Snippet call a Snippet?
Can you paste some code? Essentially we support nested snippets so your snippet can simply return a markup containing another snippet and it will be invoked. If you really want to manually invoke a snippet from another snippet and if you are not using StatefulSnippets you can just instantiate the class and call your function and pass it the right NodeSeq.

[Lift] Re: Examples of ajaxForm(...)
Imagine that your snippet has a bunch of form elements ... such as:
lift:Ajax.form
f:inputFirstName/
f:inputLastName/
/lift:Ajax.form
and your snippet function:
def form(xml: NodeSeq): NodeSeq = {
ajxForm(bind(
f, xml,
inputFirstName -SHtml.text(, (s) = {//do something here})
inputLastName -SHtml.text(, (s) = {//do something here})
) ++ SHtml.hidden(() = {
// Do processing
}))
}
So to the snippet child nodes we append a hidden element where we have
our processing function. Note that Lift automatically serializes the
form elements as key/value pairs forming a HTTP query string. Hence in
your anonymous function fir the hidden element you can just do
whatever action you want. I actually added the hidden so that when
it's called all functions bound to you form lements were executed.
The other way of working with ajax forms is to actually use jsonForm.

[Lift] Re: Setting Session Timeout?
LiftSession is bound to HttpSession through HttpSessionBindingListener
and HttpSessionActivationListener
This means that when the HTTP session terminates LiftSession will also
terminate. To verify your SessionVar that the session was purged you
can implement
override protected def onShutdown(session: CleanUpParam): Unit = {
...
}
where in case of SessionVar the session parameter is really a
LiftSession.
The LiftSession timeout is given by
HttpSession.getMaxInactiveInterval ... if that period is exceeded the
LiftSession is unbound from the HttpSession. Does not necessary means
that the HttpSession is removed by container ust that LiftSession is
terminated.
But is the problem the fact that HttpSession expired but you still had
the context in the SessionVar?

[Lift] Re: Setting Session Timeout?
Well I think I can commit something very simple that could help you,
Currently session expiration mechanism considered only the time
threshold ... but the lift GC is keeping it alive. So we can have
LiftSession#terminateHint function that just marks a flag on this
LiftSession. SessionMaster can consider this and purge the session
properly at the next sessions scan. So you can have an actor where
you're sending messages via ActorPing such as:
ActorPing schedule(MyActor, Purge(S.session), 120 seconds)
When you receive the Purg message on the received LiftSession just
call session.terminateHint. (Note that S.session is a Box
[LiftSession])
The questions would be when am I going to do this scheduling? ... Well
probably right after you are setting a value on your SessionVar.
If someone has any objections about this please do let me know.
Otherwise I could probably commit this today.

Marius

First of all, thank you for you kind words. Your website is just great but I'd recommend publishing the link on sc...@listes.epfl.ch as well. As far as Lift Scala goes, yes Lift in may respects requires understanding the Scala language and because Scala comes with new things/concepts a little bit of study is needed and I don't think programmers should fear that. After all I really think it worth it. P.S. I really like how the site looks like ... do you have a web designer or you are that good ? ... I'm asking this because we'd need a new face lilft for the Lift web site we need a persons with artistic skills and if those are combined with Scala Lift skills would be perfect. Tim Perrett mainly manages Lift site so if you are interested in collaborating with Tim I'm sure something good would come up. Tim, any thoughts? Br's, Marius On Jul 6, 7:36 am, Spencer Uresk sur...@gmail.com wrote: Hey all, I hope this isn't considered spammy, but I wanted to send out a link to a new website I built using Lift and share my experiences as a Scala and Lift newbie. I've played around with Scala off and on for over a year now, and also looked at Lift once or twice during that time. After going to David Pollak's session at JavaOne about Lift, I decided to buckle down and actually create something with Scala and Lift, as I usually learn new things best by trying to create something useful. Looking around, I noticed there weren't any Scala-specific job sites and thought it might be nice to create one. Going into it, I was a little concerned about HTML being embedded in Scala code, as the workflow (in both my day job and for my side work) is typically a designer cutting HTML and handing it to me to implement. I made sure my designer gave me valid XHTML and was pleasantly surprised at how easy it was to make my HTML code work in Lift. Even the user signup and login forms, which I got from the Mapper library, were easy to override with my HTML. On the other hand, I sort of underestimated the time investment required to get a simple site working. Lift really does require a good understanding of Scala, and I found myself frustrated by stupid things because of it. In the past, when learning Groovy and Ruby, I've used their respective frameworks to learn the language itself, and I found that didn't work quite as well with Lift. I'm not really complaining - I know that the time invested will pay off handsomely in the future - just making an observation. Really, I can't complain too much about the time it took to get up to speed - I was able to get a functioning, albeit simple, site developed in basically a long weekend, without having prior experience with Lift outside of messing with the examples for a few minutes. Here is the site I made: http://www.scalacareers.com/ Obviously it is pretty simple, but I hope it is useful. I have a bunch of other features I want to add to it as I continue to learn Lift, but if any of you have suggestions for me, please feel free to send them on over. Thank you for creating such a useful framework and for being such a friendly and helpful community - that really does make a big difference when first approaching a new language and framework! - Spencer --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Using AJAX calls in Lift Snippets
On Jul 6, 5:44 pm, Gonzalo N gonn...@gmail.com wrote:
Hello!
I am having a problem with a javascript function that creates a new
textarea from a snippet. I am using the Lift 1.0-SNAPSHOT version and
the Scala version 2.7.4.
Basically, what I am doing is creating a ajaxButton in a snippet, that
calls a JavaScript function to create new textareas, like this:
Snippet - Submit.scala
class Submit {
def createDescription (xhtml : NodeSeq) : NodeSeq = {
def accept () = {
.
}
bind(createDescription, xhtml,
function_definition - SHtml.textarea(,
function_definition = _, (id, functionDefinitionArea), (rows,
6), (cols, 60), (maxlength, 1)),
buttonFunDef - SHtml.ajaxButton(Text(Add
Function Definition), JE.Call(AddFunctionDefinition), () = {println
(pressed); JsCmds.Noop}),
save - SHtml.submit(Submit, accept))
}
}
Then in the javascript file, I have the function
AddFunctionDefinition.js that :
function AddFunctionDefinition() {
var container = document.getElementById('function_def');
var new_FD = document.createElement('li');
new_FD.innerHTML = createDescription:function_definition /
container.insertBefore(new_FD, container.firstChild);
}
I'm a bit confused .. from a JS function you're trying to call a
snippet? createDescription:buttonFunDef / ... Snippets are processed
on server side (in Lift rendering pipeine) not on client side.
Finally, in the html file, I call the Submit snippet and then creates
the button:
lift:Submit.createDescription form=post
ul
lispanh3Functions:/h3/span
ul id=function_def/ul
ul
licreateDescription:buttonFunDef //li
/ul
/li
/ul
h3createDescription:save //h3
/lift:Submit.createDescription
This button will call the JavaScript AddFunctionDefinition function to
insert in the id = function_def the
createDescription:function_definition /, but it doesn't happen! Does
anyone know why?
I've tried another alternative, I changed, in the JavaScript, the
innerHTML to directly create a new textarea:
new_FD.innerHTML = span class='file'h3Function Definition:/
h3br /
textarea id='functionDefinition' type='textarea' rows ='10'
cols='120' maxlength='5' //span;
This alternative will render the new textarea! But then I don't know
how to get the data inserted in the textarea inside the snippet, more
precisely in the accept function of Submit snippet, because when I
press the submit button, it will send all data to the accept
function.
Some help and/or hints, would be very much appreciated.

[Lift] Re: Using AJAX calls in Lift Snippets
Well this definition of ajaxButton that you use you are passing indeed
the AddFunctionDefinition function. But this function doesn;t do any
Ajax call. It receives a parameter (that is not declared btw) which is
essentially a function. You have to manually call this function in
order for the Ajax call to happen. This is a defer mechanism where
Lift passes that function that does the actual Ajax call to the user
function and the user function has to call this ajax function
received.
Note that when you ajax button is pressed the form is not submitted ..
but a simple Ajax call is made (if you would have called the function
provided to you as an argument to AddFunctionDefinition ) and only
this anonymous function gets executed:
{println(pressed); JsCmds.Noop}}
and here you are not returning anything back to browser.
What happens is this:
1. You click Add Function Definition button and
createDescription:function_definition / node is added to the DOM
tree. No Ajax request is made .. just a node in the DOM tree that has
no meaning for the browser.
2. When you click Submit the forsmis submitted and yo accept function
is called. The content of the text area is still empty cause no one
edited right?
So if you expected that by dynamically adding
createDescription:function_definition / nodes in the DOM tree will
actually be replaced with something this won't happen.
If you want to create dynamically new form elements from javascript
when pressing an ajax button you can probably do something like:
buttonFunDef - SHtml.ajaxButton(Text(Add Function Definition),
() = {
println(pressed);
JsCrVar(func, Jx(li{SHtml.textarea(, function_definition = _,
(id, functionDefinitionArea), (rows,6), (cols, 60),
(maxlength, 1)}/li))).toJs)
(ElemById(function_def) ~ JsFunc(appendChild, Call(func,
}),
But the idea is:
1. When Add Function Definition button is pressed we return a JS
expression that does:
1.1 create a func variable that represents the function generated
by Jx(..) expression. It essentially create a document fragment
dynamically based on the NodeSeq given by SHtml.textarea call
1.2 Obtain the function_def element and we're appending a child
node which is essentially an li element
2. Now when you're submitting the form that new text area should be
bounded to a new function that should be executed.
Note that I did not test the code just trying to explain the
priciples. For more references about Jx usages I'd recommend reading
the Lift book section 8.3 XML and JavaScript

Hi.
Probably I didn't explain well and I am sorry for that.
I've created a simple form in Lift processed via a snippet that
contains 3 form attributes: function_definition(a textarea),
buttonFunDef(ajaxButton) and save(submit)
In the HTML file I made the call to those attributes of the snippet,
in which one of those attributes is an ajaxButton that runs a
JavaScript function. This button, when pressed will call the
JavaScript function to add in the HTML the other attribute of the
snippet (more precisely the function_definition textarea). It sends
the POST into the server, but when the page reloads it doesn't appear
the snippet attribute and I wanted to know why.

When i try to set the Doctype to transitional, the Browser seems

These are specific cases failing independent of Lift and perhaps even
JQuery. There are numerous Lift apps out there working fine on all
these browsers. From here making a statement that Lift is broken on FF

Besides if you don't really need xhtml you can set it to html from

[Lift] Re: Actor and clusters?
Actors are local to the JVM. Scala also has RemoteActors but we don't really use them. For a lift app in a cluster environment we have to have sticky sessions concept and the reason is that functions bound to a session and mostly the references they are holding are not serialized distributed. So assuming: 1. Session 1 is created on Node 1 2. If on a subsequent request (pertaining to the Session 1) load balancer decides to dispatch the request on Node 2 you are loosing all session context including bound functions etc. This is why the load balancer must guarantee that all requests pertaining to the same session needs to be dispatched on the same node. There were some efforts in the past to integrate Terracotta but I guess there was a dead end somewhere. You can of course build you own app to not use functions bound to a session and only rely on DispatchPf style (somehow similar with Spring controllers) but that's not very lift-ish. But in this case you can persist your state in DB (which is common to all nodes) and when a request comes you just fetch the context data from DB and set your SessionVars. The problem with functions kept on the session is that those function can be lambda expression referencing members from other classes which are not serializable etc. And even if they somehow were Java serialization is bad for performance. The bottom line is that sticky sessions have the benefit of the performance because there is no state that needs to be distributed and replicated among all cluster nodes OR no need to persist the session state. But the drawback is that requests pertaining to the same session needs to be processed by the same node. IMHO using Lift apps in a cluster env. without sticky sessions can be a very tricky thing to achieve.

Well widgets don't have a whole lot of commonalities besides the init () method. Regarding destroy() that would probably be helpful for widgets that are communicating remotely with other services.

Here is my question: with the limitations imposed by GAE (no new threads) does Lift lose its scalability and concurrency advantages, or has David's alternate actor library (for Lift) taken care of this issue? Not quite. LiftActors is still using Java threads via Java's executor framework and in GAE you still can't use it AFAIK .Dave did not replace ScalaActors with LiftActors except for a single place where actors needed to be created and destroyed very often. And this happens internally. CometActors are still Scala actors. If you can live without Comet (and actors in general) and JDBC you can go ahead and use GAE.

Hey guys,
Implementing this upload progress widget with comet, I just wanted a
quick sense check about how to organize things.
As the CometActor for a particular session will be instantiated adhoc,
and the LiftRules.progessListener is global, my current thinking is to
register a given comet actor with a singleton manager actor upon its
instantiation. Giving a progressListener something like:
LiftRules.progessListener = (pBytesRead, pContentLength, pItems) = {
UploadProgressManager ! StatusUpdate(
S.session.map(_.uniqueId).openOr(default),
pBytesRead, pContentLength, pItems)
}
The idea being that when comet actors register with the manager actor
they give there sessionId and then I can ensure that only upload
progress for the current session goes to a given user (and user B
doesnt get user A's upload progress).
However, I cant help but feel this is a little messy? Thoughts?

Inside your snippet you can use S.attr(variable) to get the value of the variable. But what is the use case? ... what are you trying to solve? Its a long shot but if you have any idea please do tell! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

HI there,
I know, there have been several other threads around the topic but I
just wanted to yield somethings here. In the past few days I've been
talking with Tim as he was having problems with his FileUpload widget.
Even with short polling the progress was not reported even though the
LiftSession.progressListener was properly called.
Today I started to look into it and here is what I've done:
1. Here is the markup:
iframe id=upload_target name=upload_target src=# style=width:
0;height:0;border:0px solid #fff;/iframe
lift:Upload.render form=POST multipart=true id=upload_form
target=upload_target
f:inputFile/

/lift:Upload.render
A simple snippet that uses the invisible iframe trick to upload
stuff in the background. The so called Ajax upload. (I had to add
the target attribute into the supported form snippet attributed but
that's ok)
2. In boot had something like:
LiftSession.onSetupSession = ((session: LiftSession) = {
session.progessListener = Full((chunk, total, index) = {
Thread.sleep(100)
println(index + read + chunk + out of + total + +
Thread.currentThread)
})
}) :: Nil
Just monitor the progress ... and to make it last a little longer
I'm sleeping for 100 milliseconds
3. I set the GC polling to 10 seconds. The think is that GC polling
would be just like the short polling for getting the progress status
back in the browser.
The behavior that I observed was that while I was uploading a 30 Mb +
file the polling requests timed out after 5 secconds per
LiftRules.ajaxPostTimeout. This means that our progress monitoring
ajax request would have timed out as well. On the server side the
execution got stuck until the upload was complete.
LiftServlet.handleAjax was not called until the upload terminates.
Initially I thought that this has to do to limited request channels
that browser have but the thing is that we have several places in Lift
code where we synchronize things. Such as LiftSession.getSession,
LiftSession.fixSessionTime etc. Acquiring these locks made the
progress polling to hang until the upload terminated. Of course
removing th synchronized block made the polling to work right during
the file upload. Now this was just for test ... I'm not suggesting to
remove the synchronized blocks as we'd loose consistency but this
looks to stay in the way of properly dealing with multiple parallel
request per same session like fileupload and progress monitoring.
It appears that there is either a thread starvation situation or
simply a lock that is held while upload is is progress.

[Lift] Re: Article: Lift snippet selection - DispatchSnippet vs snippet reflection
Good article but do you have some concrete benchmarks between Snippet and DispatchSnippet? In modern JVM memory allocation is pretty cheap due to heap preparation JVM makes and reflection invocation doesn't bring too much overhead ... not anymore. The article seams to present the two from an optimization perspective but I don;t see much optimization here. Of course DispatchSnippet invocation is faster but the question is how much. And for say thousands of concurrent requests per cluster node I have the feeling that the delta is not that significant. Furthermore these deltas become totally negligible when during a request life cycle we're hitting DB-s. remote services etc. Personally I don't really agree regular snippets should be used in Dev mode only, well not until I see some compelling numbers.

[Lift] Re: Template tags and properties
Lift is not a MVC framework but a View First one. Snippets are the way
to generate dynamic content that will be woven into the resulting
markup. There is no design break in fact it is one of the most
fundamental design goals of Lift. Snippets work with markup building
blocks to generate the proper outcome. This is not a bad thing, quite
the opposite. However every framework out there can be used improperly
in this case using tons of markup in the snippets doesn't make too
much sense.
If you still feel that you want to make a comparison between Lift and
MVC snippets are not controllers. You can think of snippets as
rendering helpers that sits very close to the templates ...
Static Templates + Snippets = Resulting Markup That Contains Dynamic
Content

[Lift] Re: Acceding object fields in template
Not sure how much it worths but I'm having second thoughts about this because it feels to me like it drifts away from the Lift's templating idiom. Accessing arbitrary objects properties/methods seems to bring lift closer to JSF kinds of things and I don't really see what problem this actually solves as snippet invocation. lift:product.name / can simply return a Text(product.name) ... or with implicit conversions just: def name(xhtml: NodeSeq): NodeSeq = product.name Bringing data objects into template giving them global page scope seems to me that it kinda opens Pandora's box.

This caused the entire jsTree to fail to render properly, making it non- functional. I'm not entirely sure why it did what it did, but until I stripped out Lift and ran it just as an empty servlet I couldn't see what was going on. For some reason the lift served version stripped the class off of a ul (in my case it was only one, but I had a very simple tree).. the class for the ul was ltr and it's gone in the lift version. This ul is generated by javascript using jQuery, so I'm not sure what's going on there. Anyway, I've decided since all my dynamic content is coming from other webapps, I might as well just serve my static content from a bare servlet, therefore cutting down on any variables.

[Lift] Re: how to create a dynamic form in lift?
There are several ways of doing it: 1. Use JSONForm (http://wiki.liftweb.net/index.php/ HowTo_use_JSON_forms) in conjunction with JSONHandler and create new Input fields purely from JavaScript and adhere to your own naming conversion. 2. Before submitting the form start an Ajax request to add a field. On your Ajax request processing function you can create a new input field, associate your field function and return the JS back to client which will add the input field to your form. Hence when you are submitting the form, all your bound functions will be executed.

Now I want to add a button that adds an additional field, but I don't know beforehand how the input of this new form field should be handled. The options a user can pick from is fixed (for instance numeric field, text field, email field, etc.) so that I can write validation and handling for a specific type, but the user should be free to add as many fields as he likes, of any type he likes. Let me give you an example: the current form contains: name, display name, date of birth. One user clicks a button, and wants to add a phone number field, so that his form will display: name, display name, date of birth, phone number However, another user might add another type of field, for instance a zipcode field, so that his form will display: name, display name, date of birth, zipcode Of course, a field that expects a phone number should be validated differently than a field that expects a zipcode. How do I create this dynamic kind of form, since I can not map the form fields directly to a fixed set of objects in my snippets, because this is not known beforehand, but depends on user input.

Why? ... because with this mechanism you don't need Lift's functions binding and inherently field naming generation. My notes are NOT related to Mapper in fact this is persistence agnostic.

If you need relationships to be kept track of but not actually created, store the delta in your StatefulSnippet -- current, added, and removed children lists; then display a list of actual items by concatening current and added, and filtering actual.filter(a = removed.forall(a.ne)). If the relationships are more complex, you may want to wait for me to commit my one-to-one and one-to-many additions to Mapper in the near future BH. I am actually doing something pretty similar, and I hope to commit soon a number of utilities to make this easier. I'm assuming that you have tables and Mappers all set up to support this kind of data structure? - marius d.marius.dan...@gmail.com wrote: There are several ways of doing it: 1. Use JSONForm (http://wiki.liftweb.net/index.php/ HowTo_use_JSON_forms) in conjunction with JSONHandler and create new Input fields purely from JavaScript and adhere to your own naming conversion. 2. Before submitting the form start an Ajax request to add a field. On your Ajax request processing function you can create a new input field, associate your field function and return the JS back to client which will add the input field to your form. Hence when you are submitting the form, all your bound functions will be executed.

For instance, say I have a form with the fields name, display name and date of birth. Of course, I can create a a snippet where I can do my validation and other handling. Now I want to add a button that adds an additional field, but I don't know beforehand how the input of this new form field should be handled. The options a user can pick from is fixed (for instance numeric field, text field, email field, etc.) so that I can write validation and handling for a specific type, but the user should be free to add as many fields as he likes, of any type he likes. Let me give you an example: the current form contains: name, display name, date of birth. One user clicks a button, and wants to add a phone number field, so that his form will display: name, display name, date of birth, phone number However, another user might add another type of field, for instance a zipcode field, so that his form will display: name, display name, date of birth, zipcode Of course, a field that expects a phone number should be validated differently than a field that expects a zipcode. How do I create this dynamic kind of form, since I can not map the form fields directly to a fixed set of objects in my snippets, because this is not known beforehand, but depends on user input. I hope you understand my question, and that you have some good suggestions. Thanks!
