Hello, I would really would like to have this type of support from lift. I looked at GWT and think this is a nice way. They use url parameters after a '#'. I dont understand the process because I have very little javascript knowledge. But I am thinking, lift is creating unique function names and is calling them with ajax. Maybe there is a way to have the functions be called over a way like GWT?

Hello Timothy, there is nothing stoping me from using it. But when I think of a framework it would be nice to "activate" backbutton support. I think this is somethink a lot of people would appreciate to have and not everybody should have to build this from the ground up. I do not have to deal with this now but in near future.

[Lift] Performance related question
Hello everyone, I am surprised about the few code I have written and the effect I get :) I would like to know if this workflow can be optimized: I my snippet method I "findAnyTemplate()" my xml fragments and assigning them to vals. Then I have little functions that bind content with the above xml fragments and return the resulting NodeSeq, so I can do easy an SetHtml and return the new content with ajax. I find this way very easy. So I can have many little fragments, load them bind content and return them via ajax. Is it ok to load the fragments and save them in vals? Or can I do a findAnyTemplate() all the time? Or should I have snippets methods for this fragments and let lift do the snippet method calling? with best regards -- You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: Ajax button + submitting a form
Hello,
I have a similar use case. For an AjaxForm you have to write:
SHtml.ajaxForm(
bind("mytags", xml,
// binding to your tags ...
"submit" -> SHtml.submit("do it", save),
) ++ SHtml.hidden(save)
)
You dont need to have a form element in your templates for this to
work
because ajaxForm will wrap the result of the bind method.
For my listelements checkbox, I attach to the checkbox a function,
that adds an Id and the
checkbox value to a ListBuffer[(Boolean, String)]. (checked and not
checked boxes are submittet)
Then I filter the List for the selected values a do what I have to do
with them.
I the above code example, my save method does some db stuff and then
returning
a JsCmds.SetHtml("an html id", some html/snippet nodeseq) for a
redraw.
Hope this helps a little
with best regards

[Lift] Re: SessionVars in different snippets
Hello,
David I like the SessionVar Idea and the type safety.
But as Alex suggests, can I define an object with the fields?
I think now when I am writing this I think I understand it more :D
I thought it is not possible to have one object that stores the
values.
But the SessionVar knows what user is requesting a value right?
Because SessionVars were always defined inside the snippet class
I thought the SessionVar gets the context from the snippet class

[Lift] Re: SessionVars in different snippets
Hello, I dont have to use SessionVars until now, but in near future. But I had the same problem in mind. Is there not a central place to get the user session with all the values stored?

Hello Marius,
No there are no error messsages in the console window.
This is the generated form:
Under the firebug network panel I see that there is a post ("x" is
typed value in the textfield):

And the response for this post is empty.

I see that I get the predefined alert.

[Lift] Re: Form submit and Ajax
Hello again,
I think I found an error in the form processing, correcct me if it is
not:
This is the snippet:
class Test {
object name extends RequestVar[String]("init")
def render(xml: NodeSeq): NodeSeq = {
def printName(): JsCmd = {
Log.debug("name = " + name.is)
JsCmds.Alert("an ajax response! "+ name.is)
}
SHtml.ajaxForm(
Helpers.bind("atest", xml,
"name" -> SHtml.text(name.is, name(_)),
"submit" -> SHtml.submit("add", printName)
), JsCmds._Noop, printName
)
/*
SHtml.ajaxForm(
Helpers.bind("atest", xml,
"name" -> SHtml.text(name.is, name(_)),
"submit" -> SHtml.submit("add", printName)
) ++ SHtml.hidden(printName)
)
*/
}
}
This is the template:
The problem is with the uncommented ajaxForm code, when the form is
submitted the name RequestVar is not updated. I seems that the
function
bound to the name-Textfield is not invoked. So I get back "an ajax
response! init".
But the commented ajaxForm code gives me a correnct result. If I type
"name" in the
textfield I get "an ajax response! name" back.
with best regards

[Lift] Re: Form submit and Ajax
Hello Alex,
thank you for the answer.
Ok I will check it again set up a little example.
Is this a "lift" way workflow?
- show a page with a form
- data is submitted to snippet
- data is evaluated
- get other fragments/templates and bind the values for them
- invoke SetHtml that should replace div content on the page
> Not unless you're specifically calling templates, etc.
Do I have to load my fragments with templateFinder and then
invoke other snippet methods that are intended to process the
templates xml or is there another way so that Lift can do it.
with best regards

[Lift] Form submit and Ajax
Hello,
In a previous post I had the problem that my form was not send with
ajax.
With the help of Marius and Timothy I got it working.
(http://groups.google.com/group/liftweb/browse_thread/thread/
d052ed7191561ef1)
I have to questions.
Now I want, after the form is submittet, to fetch an object from my DB
do something
and update the site.
I tried the following:
def add(xml: NodeSeq): NodeSeq = {
def addBookmark(): JsCmd = {
// fetch the object from DB
JsCmds.SetHtml(WebHelper.MAIN_DIV_ID,
TemplateFinder.findAnyTemplate
(WebHelper.bookmarkEdit).open_!)
}
SHtml.ajaxForm(
bind("bookmark", xml,
"url" -> SHtml.text(url, url = _),
"submit" -> SHtml.submit("add", addBookmark)
), JsCmds._Noop, addBookmark
)
}
I hoped that the addBookmark method would be invoked after the form
is submitted and that the returned SetHtml will set the new snippet
fragment (that should be processed by lift).
The new fragment is a new form:
Is there a better way to do such ajax fragment replacements? would
like to know more about.
Are the NodeSeq that should be replaced with SetHtml processed by
Lift?
The second thing is, that when I am trying to make a browser request
to view the page,
the addBookmark method is already executed. Was this intended?
with best regards

Ok I did not use the archetypes. But I did not read this elsewhere.
Would be good to have this noted in the lift book or in the lift wiki.
I will post a comment on the liftbook group.
I will test it again with jQuery referenced.

[Lift] Re: Form does not want to send
I dont think I have to take care to reference jQuery myself for lift.
Lift should insert the version it needs automatically.
Ok I can workaround this by inserting a jquery reference, but I see
that jquery is in the lift sources.
The LiftBook states that by default the LiftRules.jsArtifacts variable
is
pointing to use jQuery by default.

[Lift] Form does not want to send
Hello Lift people!
I am experimenting with Lift for building a web application.
I read alot on the list on the ajax subject and I think I get more
familiar with.
I try to get a form submittet with ajax. I want an easy solution
without much
code writing. I tried the following suggestion as found here in the
list:
SHtml.ajaxForm(
bind("bookmark", xml,
"url" -> SHtml.text(url, url = _),
"submit" -> SHtml.submit("add", addBookmark)
) ++ SHtml.hidden(addBookmark)
)
I am using a StatefulSnippet. My little template:
The form gets rendered but not submitted when the "add" button is
clicked.
I have a freshly build 1.1-snapshot and using simple-build-tool
(running jetty).
Do not understand it. Without Ajax it works.
with best regards

[Lift] Re: Funny behavior of head merging with nested head blocks
Hello,
I have a head element in my default template with a standard title
element.
When I define a head element in my snippet with a new title element,
it is appended into the head section of my resulting html.
Now there are two title element and the browser uses the first one.
I thought the title element in my default template will be replaced
with the one I defined in my snippet.
Is there another way to achieve this?

[Lift] Confused about validation
Hello lift people, lift seems very promising. I am trying to make some tests and examples because I am new to lift. I wanted to add some validation to a form element and show the validation error to the user. But after little searching I was a little disappointet to see that there is no such support, exept when using Mapper. I do not want to use Mapper. I want only simple field validation with the errors messages printed in a feedback panel. Before lift I was using Wicket. I think they did a good job with the validators. I try to understand why lift has not such support? I do not want to code everything in my submit method and validate things there. best regards -- You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Structuring Web Application
Hello Lift Community, I want to implement a new Project in Scala with Lift. I am new to Scala/Lift. Scala looks great and it expanded my horizon. FP is a new concept to me. My background is Java and a little bit of Spring. I read three Scala books and a lot on blogs. But there is a missing part for me on how to combine my classes. I read the Scalable Components Paper and I dont get it 100%. I need a little bit more input on structuring a web app and I hope to get the 100% with you guys. With Spring you let the container manage the classes. ok. I think my problem is, I dont know how you structured a web app in days without Spring. I would like to have Lift access my domain logic over an application layer (Domain Driven Design). In Wicket I would have my SpringBean annotation. So I hope to understand, how - can I access my app layer? - how could I organize my domain logic. I want to use DDD. I know I have to use "object" and "class" in a bigger sense...? I hope you guys can give me some hints. Thanks a lot --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.
