[Lift] Re: getting started feedback
Hello, I had the same problems too.

Had a few points that threw me a bit. The biggest one is probably having a snippet named TD and a model named ToDo. It seems to me like it's trying to work around namespace collisions and/or potential confusion over namespaces, I think it would probably be a better idea to address that explicitly. What do people generally do for naming snippets? Is naming them after the Model the exception rather than the rule? Another thing that got me was that it didn't address adding new pages past index.html which strikes me as somewhat incomplete... After reading the getting started guide, I feel I'm going to have to find another document or two (or three) before I can do any meaningful work with the framework. Other than those two suggestions I found it a pretty good introduction, the framework is definitely pretty neat, and I like the mvn integration for getting started, very handy -- 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

Hello,
I have a regular form, which is submitted with a POST (no AJAX here yet). The
form contains a list, to which you can add and remove elements using AJAX. So
the add and remove buttons are:
add - ajaxButton(Add element, () = { elements += new Element; reDraw })
The reDraw method is a SetHtml for the whole form. Now this almost works,
with the exception that when I press the add button all other changes in
the form are discarded, as the form is not submitted. So, when the button is
pressed, I would need to submit the form using ajax and execute a given
function on the server. In the archives I found SHtml.submitAjaxForm(formId)
method, which I guess does what I need, but I don't know how to combine it
with an ajaxButton?

If any of the folks out there that name things better than I do (at least I didn't call it Apply_A_Tron), please feel free to suggest name changes, variance changes, etc. Thanks, David -- Lift, the simply functional web frameworkhttp://liftweb.net Beginning Scalahttp://www.apress.com/book/view/1430219890 Follow me:http://twitter.com/dpp Surf the harmonics -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Form does not want to send
Hello,
You need to change the html to:
lift:Bookmark.add form=post
Otherwise lift does not render for the form element.
No the forms are rendered in html. I think the form=post is only
needed when ajaxForm is not used.
But I see now in the Firebug Console that the liftajax cannot find
jQuery.
jQuery is not defined
http://localhost:8080/ajax_request/liftAjax.js
Line 157
jQuery is not defined
http://localhost:8080/bookmarks/add
Line 105
For the second error this is the generated JS in my html:
script type=text/javascript
104 // ![CDATA[
105 jQuery(document).ready(function() {liftAjax.lift_successRegisterGC
();});
106 var lift_page = F1160735200508JPL;
107 // ]]
108 /script
The liftajax.js file is found.
The lift version I am using is a freshly build 1.1-snapshot of the
lift-base module.
with best regards

[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 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:
lift:Bookmark.edit
bookmark:url /
bookmark:title /
bookmark:submit /
/lift:Bookmark.edit
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?

[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.

I can't think of a better way right now; what you're doing is pretty
standard.

No, that's not supposed to happen. I'm guessing you're calling
addBookmark() somewhere else in your code.

[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:
lift:surround with=default at=col3
lift:Test
atest:name /
atest:submit /
/lift:Test
/lift:surround
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.

[Lift] Re: Form submit and Ajax
Hello Marius,
No there are no error messsages in the console window.
This is the generated form:
form id=F587106754336BUG action=javascript://
onsubmit=;liftAjax.lift_ajaxHandler(jQuery
('#'+F587106754336BUG).serialize(), function() { alert(an ajax
response! init);; }, null, javascript);return false;
postsubmit=alert(an ajax response! init);
input type=text value=init name=F5871067543340QE/
input type=submit name=F587106764335BDR value=add/
/form
Under the firebug network panel I see that there is a post (x is
typed value in the textfield):
F5871067543340QEx
And the response for this post is empty.
with best regards
I see that I get the predefined alert.

[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: lift:surround with=default at=col3 div id=addb lift:Bookmark.add bookmark:url / bookmark:submit / /lift:Bookmark.add /div /lift:surround 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 -- You received this message because you are subscribed to the Google Groups Lift group. To post to this group, send email to lift...@googlegroups.com.

[Lift] Re: Lift is awesome (with reservations)
Hello, It would be great to see some more bind examples in more complex scenarios and how different snippets can work together. How to build fragments and replace fragments for ajax. I think the people that do a lot with lift have some patterns for this. Are there any Idioms out. This is my problem area. with best regards On 26 Dez., 15:30, Marius marius.dan...@gmail.com wrote: While I admit that there is not yet enough documentation material or at least probably not in a single place I disagree with some complaints. The Lift book for example describes in quite detail that request processing lifecycle, disspath functions, rendering pipeline, LiftRules, S, SHtml, LiftResponse-s, binds, JavaScript abstraction and many others etc. Sure new things came up in the mean time and we're trying to document them as time permits in many cases. About the Lift structure being too messy, what do you actually mean? AFAIK historically, people (a many newbies) asserted the contrary that they really liked the Lift concepts, the ease of use and understand how it works. For naming conventions there was a project opened and even discussed on this public list about renaming API's but AFAIK there was not a whole lot of feedback on this list so unless I'm wrong, the decision was to do ad-hoc renaming as we work on various things. This may mean deprecation of old names so there will be a smooth transition to better names. So I believe it is much more constructive for ALL of us to ask concrete questions, described concrete problems and let's see how we can fix it. Many things though may be subjective and leading to endless discussions without substance.

[Lift] Re: Lift is awesome (with reservations)
Hello, I would like to hear more about, how you get lift. I am new to lift too and trying to get a better and clearer viewpoint. Maybe it can help others to. If you can summarize it in a few sentences. This would be really great. with best regards On 25 Dez., 01:05, Erkki Lindpere vill...@gmail.com wrote: It took me a long time to get lift. For about a year I looked at examples from time to time and tried out some basic stuff, but it just didn't click. I found the structure to be too messy. I still do actually. It seems that the documentation is also not well structured enough for getting started and I had to look at examples and Lift's source to understand how things work (thanks for putting sources in the Maven repo BTW, I wish everyone would do that). After experimenting with Lift for about two days I think I get the basic idea and I've come to a better understanding about lift's structure by looking at the sources, I can now ignore the parts I don't like (Mapper being one, I use JPA instead) and use the parts that I do. The way the X(HT)ML processing, type-safe JavaScript/jQuery, Ajax and Comet work is just brilliant! PS. I'm working (on my spare time for now) on an Ajax Comet heavy application that will hopefully also have a lot of runtime customization ability through OSGi. I haven't gotten to the OSGi part yet, because there's the hurdle of OSGifying all the jars I use and I want to get a good understanding of Lift before I start making things dynamic. But do you have any recommendations for OSGi framework/web container combinations to use with Lift? I have tried SpringSource dmServer (with the SpringSource tooling), but I don't like it much... Maybe plain Equinox + Jetty with the ScalaModules library would be a good combo? -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Beginner Ajax question - redrawing a page fragment
Hello,
it would be nice to see some more examples for ajax.
I am new to lift too, and I am trying to get the view point
of how to work with lift.
Some Idiom or standard way to say replace this with this snippet
there
in a how-to would be great to have.

Hello,
A couple of observations...
First, having some XHTML in your Scala code is not a bad thing. When the
XHTML declares the meaning (not the layout) of the information, it's my
opinion that it's okay. This means that:
ul{list.map(i = li{i}/li}ul
Simply defines an unordered list. It does not declare how to lay out that
list. The layout should be controlled by CSS.
True, xhtml can also be considered as logic. You got me convinced ;).
TemplateFinder.findAnyTemplate(List(snippets-hidden,
userList)) openOr NodeSeq.Empty)
Worked great; lots of Lift API to explore still :).
If you don't mind, I'll put the results of this thread in a
tutorial-ajax-followup wiki page? I think quite a lot of people may want to
do something similar.

[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?
with best regards

I was diagnosing some incorrect HTML in our application using Lift,
and I found a strange behavior of head merging (I assume) when you
emit a head tag into a head tag from the snippet. The code speaks
better than I do about this:

object Dialog extends DispatchSnippet {
val standardDialogOptions: JsObj = JsObj(
autoOpen - false,
bgiframe - true,
modal - true,
resizable - false
)
val dispatch: DispatchIt = {
case head = renderHead
case render = render
}
def renderHead(ns: NodeSeq): NodeSeq =
head{ Script { JsCrVar(pxStandardDialogOptions,
Dialog.standardDialogOptions) } }/head
...
}
LiftRules.snippetDispatch.append {
...
case Dialog = Dialog
...
}
lift:surround with=default at=content
head
titleEmail Editor/title
lift:Dialog.head /
/head
/lift:surround
I agree I'm doing the wrong thing here -- the lift:Dialog.head / tag
rightly should be outside of the head block, or the snippet should not
emit head. However, the resulting behavior is funny (certainly more
funny than I'd expect):
html xmlns:lift=http://liftweb.net/; xmlns=http://www.w3.org/1999/xhtml
head
...
titleEmail Editor/title
script type=text/javascript
// ![CDATA[
var pxStandardDialogOptions = {autoOpen: false, bgiframe: true,
modal: true, resizable: false};
// ]]
/script
headscript type=text/javascript
// ![CDATA[
var pxStandardDialogOptions = {autoOpen: false, bgiframe: true,
modal: true, resizable: false};
// ]]
/script/head
/head
...
/html
Ideally I'd like this to just work so that it doesn't matter
precisely where the snippet is called, though it would be some special
magic just to work around an erroneous case. But, the behavior that
does happen seems odd, duplicating the markup inside the head?
Should I file a bug? Just smile and nod?
If we had to recursively check all the head tags for head tags, that
would significantly increase the overhead of the rewrite phase. I would
suggest using the new Helpers.stripHead() call to remove head tags from
stuff you already know is in a head tag.

[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.
