In terms of disabling the submit button until the input is valid, that's all
client-side JavaScript and no server-side Scala code. :-(  This part of the
page is static in that no matter the server state, the client code will be
rendered in the same way.  There is no snippet or controller or anything
else that changes the state of the submit button.

In terms of what happens when you want to submit, see the code at:
http://demo.liftweb.net/json

This is what you want to do... when the submit button is pressed (after the
client-side script has enabled it), you want to grab the values of a couple
of form elements and pass them as parameters in a JSON call.  On the server
side, you use pattern matching to extract the parameters and perform the
action.

See if you can make this non-comet code work first.  Once you get that
working, we can hook in the push of results back to the browser.  Also, I'd
encourage you to copy the code from the Json.scala and json.html files in
sites/example as a basis for your code.

Thanks,

David

[Lift] Form Question

[sailormoo...@gmail.com]

Hello:

  It's me again. I would like to ask how to generate the following
form tag with attribute.


 This form needs the following feature:
 1. specifying the action link, with an parameter and #game_top
 2. the target isn't the same window, it's another window
 3. with an Javascript onSubmit to it

Thanks for the help.

[Lift] really basic lift question

[Meredith Gregory]

Charles, et al,

i'm trying to do something dead simple and it is exposing all kinds of
ignorance on my part regarding lift. (Yay! i get to learn new stuff -- which
would be great if i weren't under a terrible time crunch.)

Now, all i want to do is create a form with

   - 3 text boxes
   - 1 submit button
   - and an area for rendering a chart that results from a computation on
   the values of the text boxes

Here's the minor complication. The submit is going to kick off a process
that may be quite long running. So, i'll render immediately what's possible
with the existing data and then when the long-running computation gets back
to me i'll refresh the feedback. i thought this would be a poster-child app
for the comet support. But, i'm realizing i don't really understand how

   - bind
   - text
   - submit
   - ...

work and i find it difficult to navigate to their defns. For example,
suppose i want the submit button to be greyed-out and inactive unless the 3
text boxes have validated input in them. What is the simplest pair of a
snippet and controller that will do that?

Best wishes,

--greg

[Lift] comet sample app rendering problem

Lifted,

i'm trying a minor variation on DPP's comet screencast and am running into a

[Lift] Re: Move common dependencies into parent POM?

[Daniel Mueller]

Not a complete solution (as that would indeed require additional
parents): The parent pom already has a dependencyManagement section,
which can indicate which exact version of a dependency should be used
in a child. Currently it's only used for the scala-lib and for the
servlet api. See [1] for more information and an explanation. Could be
used for more. To see a full fledged use case, check the ActiveMQ
parent pom[2].

There seems to be also the new possibility of importing dependencies
from one module into another [3], which would pretty much solve the
exact at hand. But it has been only introduced in 2.0.9, and it might
have some negative impact on the maven experience for users (Basically
there would be an additional 2.0.9 tag in pom to indicate that maven 2.0.9+ is required.
Discussed in the pom reference at [4]).

Cheers,
Daniel

The "default" way to do snippets is naming by convention.  In your terminal
window, there should have been an error indicating that the snippet was not
invoked.

You can also register snippets:

In Boot.scala:

LiftRules.snippetDispatch.append {
  case "MySnippet" => MySnippet
}

object MySnippet extends DispatchSnippet {
  val dispatch = {
case "foo" => doFoo _
  }

   def doFoo(in: NodeSeq): NodeSeq = bind()
}

[Lift] Re: how to add object into session scope in lift

[Andrew Scherpbier]

I totally concur on the awesome explanation.  As a matter of fact, can a 
committer add some of this stuff (maybe not the scala stuff but the 
actual explanation of the SessionVar) to the scaladocs of the SessionVar 
class/object?  That would be a great place for this kind of documentation.


For me, the lack of usable scaladoc is really making it hard to learn 
lift.  I've been toying with the idea of submitting patches to add docs 
as soon as I figure out some stuff...  Problem is that it is going way 
too slow.  A specific example would be the quote from section 6.2.4 in 
the "Eploring Lift" draft that reads: "The CRUDify behavior is very 
flexible, with plenty of defs you can override to control the templates 
for pages..."  Then you go to the API docs for CRUDify and there are 
loads of cool defs, but no documentation what most of these do and what 
an override would get you.  For the ones that have docs it is just a 
single line that doesn't really help that much.
There is the source code.  That's great.  But unfortunately for me, 
Scala is still very much a write-only language since I'm still 
learning.  I know that's my problem, but I know I'm not the only one!  
(I'm learning (and liking!) Scala because of Lift, just like lots of 
people learned Ruby because of Rails.)


So, I want to help, because I think Lift is just about the coolest thing 
out there, but it is going to take a while for me to be able to 
contribute.  In the mean time, I would ask those in the know to try to 
add some docs to the code.

BTW, this mailing list of great.  The responses are *very* helpful.  
Keep them comin'!

[Lift] Re: namespace problem again

[Meredith Gregory]

David,

Thanks, as always, for your responsiveness. i don't know if you saw my
earlier post, but i found and fixed the problem. However, now i'm running
into a more subtle problem related to how the JSRaw is handled. See below.

Best wishes,

--greg

Here's the error according to firebug

F507651869906K3V is not defined
onclick(click clientX=479, clientY=201)6FsTX8d6...J7Q%3D%3D (line 2)
(F507651869906K3V, lift_ajaxHand...TimeField").attr("value"), null, null));

function onclick(event) { (F507651869906K3V,
lift_ajaxHandler("F507651869906K3V=" + $("#initialTimeField").attr("value")
+ "--" + $("#finalTimeField").attr("value"), null, null));
 }

The code that causes this problem is the handler for the onclick event for
the button. As near as i can tell, my raw JS is fine. This seems to have to
do with how the JsRaw is generating the onclick code.

  def show(xhtml: NodeSeq): NodeSeq = {

  Inital time :
  { text("Now", (updateInitialTime _)) % ("size" -> "60") % ("id" ->
"initialTimeField") }

  Final time :
  { text("Now", (updateFinalTime _)) % ("size" -> "60") % ("id" ->
"finalTimeField") }

{ {?("Go")} %
   ("onclick" ->
ajaxCall(JsRaw("$('#initialTimeField').attr('value')+'--'+$('#finalTimeField').attr('value')"),
s => updateChart(s))) }
  
  {whatNode()}

  }

Lifted,

Sorry for the sound and fury. i found the soln again: the following call had
gotten mangled in boot

LiftRules.addToPackages("com.biosimilarity.weather")

That's a nasty one to get wrong. No help from the compiler. Error message
completely misleading.

[Lift] Re: namespace problem again

[Meredith Gregory]

Lifted,

It appears that the interface for binding a namespace is side-effecting.
That's fine. But, i can't seem to understand the semantics. For example,

   - if one puts a call to bind at the beginning of a block for a method
   that handles a post, and yet returns a different nodeseq, the desired effect
   is not present.
   - If one nests the bind call inside the construction of a nodeseq, the
   effect is not present.
   - On the other hand, if one puts a call to bind on a completely different
   form, the desired effect is present in the post handler.

i find that a little confusing. Is there a clean, simple model that will
help me understand how to use bind?

Best wishes,

--greg

[Lift] Re: namespace problem again

[Meredith Gregory]

David,

Thanks for the suggestion, but no joy. The error is the same. BTW, the only
difference i could spot between your proposal and mine was changing the
"-->" to "->".

Best wishes,

So if I understand you correctly, "/date_{date_format}" will become magic
anywhere in url request paths.  so these work too:
classpath/js/date_2009_04_29_18_20/json.s   or
/foo/bar/date_2009_04_29_18_20/json.s.

That's ok with me, though it's a bit more aggressive to mess with the
segments of the mapping of the url path to file system path.

Potentially could use dates on directories then too, although I'm not quite
sure why.  e.g.  foo/date_2009_04_29_18_20/bar/json.js would check the
modification date of the bar directory..

I'd imagine this also needs to work for non-/classpath served files.  Does
that push us back to the params style?

[Lift] timestamp versioning for javascript includes

[Lee Mighdoll]

I'm trying to avoid having to clear the browser cache when I change a
javascript file.

One approach is to append a timestamp to the script src tag in the html
file.

  

becomes:

  

I'm told rails uses this approach.  Is there already a handy way to do this
in lift?  Or is there a better way?

Happy to try and make a snippet for this if it's useful for others.

Sure... if you can make that happen, wicked cool.

Note that some Lift modules (e.g., lift-textile) should not depend on

Changing a few things that Tim said.


>
> 1. how object extends class in scala.?


object creates a singleton... an instance of the class that can be shared
within the scope that it was created.  If object is used at the top-level
scope, then it is a singleton shared by all classes in that classloader
(your Lift app.)

In Scala everything is either an instance of an object or a method.  This
means there are no statics, no primitives, etc.  In order to have a
singleton instance shared within a classloader, use the object mechanism.


>
> 2. are we going to create object of SessionVar class?


Yes, we create a singleton instance of the SessionVar class.  The SessionVar
class uses a little machinery to access the backing store of your session.
 So, the SessionVar doesn't actually store a value.  It is a proxy that gets
the current session based on the context of your thread, it has a globally
unique name and uses this name to look up the underlying value in a hashmap
in the session and then casts it to the type of the specific SessionVar...
in this case HashMap[String, Int].  In this way, you have type-safe access
to session data.  This is a material advance over the way session data is
stored in a Java session... there's no casting on the user's part.


>
> 3. are we calling constructor of given class?


Yes.  However, if you take a look at the SessionVar's constructor, it's as
follows:

class SessionVar[T](dflt: => T)

This is a "call-by-name" parameter.  So, it's a function rather than a
value.  Why do we do this?  This allows us to create a new instance of the
default value of the SessionVar each time it's needed.  When you call the is
method on the SessionVar, Lift looks to see if the SessioVar has been
defined.  If it has not been defined, then the default value creator
function is applied and we get a new default value, the SessionVar for the
current session is set to that default value and the freshly minted value is
returned.


>
> 4. is it similar to java class which extends other class ,and then create
> object of subclass?


Scala creates a subclass of SessionVar for your singleton.  If you do
sessionObj.getClass.getName, it will not be SessionVar, but some
compiler-generated name.   See the answer to #1.

[Lift] Re: developing Scala/Lift using Eclipse

[Josh Suereth]

It should be innocuous.  (Assuming no typing errors).  It will also fix some
of your mvn eclipse:eclipse woes.

Remember though, using mvn eclipse:eclipse does *not* give the "Scala IDE
for Eclipse" any chance to fix/edit its configuration.   Most eclipse
plugins assume they have full control over *their* configuration and when
doing things through eclipse APIs, they have a chance to respond and tweak
the project settings appropriately.   This means that any bugs you run into
in eclispe should be reproduced without using mvn eclipse:eclipse.  This is
why you should prefer eclipse plugins, rather than maven plugins, to do
integration between Scala + Maven + Eclipse.

sessionObj.is gets the contained object from the SessionVar.  In this case,
that object is a HashMap.

The + method is on HashMap:

HashMap does not have an apply(p: Pair[??,??]) method, so this would not
compile.

It's the Scala parser.  It converts the contents of  blocks to
escaped XML.  For example:

scala> 

res5: scala.xml.Elem = dog & foo

If you absolutely need the CDATA in your XML (for example, this is necessary
in the browser when sending down JavaScript and CSS), you can use:


scala> {PCData("dogs & cats")}
{PCData("dogs & cats")}
res6: scala.xml.Elem =

[Lift] Re: how to add object into session scope in lift

[Timothy Perrett]

1. Object is like a static class in Java ­ but better.
2. Its not instantionation in that sense, so by proxy not "creation"
3. Scala objects have an apply method, of which, MyObject() is a shortcut
to. Think of it as being the same as MyObject.apply(...) etc.
4. It is indeed a subtype similar to subclassing in Java.

Does that help?

[Lift] REST and CDATA

Hi,
I am building a rest service and running into trouble with cdata which

I am trying to do something like this:

def toXml() = {

[Lift] Move common dependencies into parent POM?

[Heiko Seeberger]

Hi,
For my work on OSGi-fying Lift I took a closer look at the POMs. I noticed,
that dependencies are duplicated across the modules, e.g. lift-util and
lift-webkit both declare almost the same dependencies.

What's the reason for that? Wouldn't it be better to move the common
dependencies into the parent POM / multiple parent POMs?

[Lift] Re: Javascript "confirm(..)" dialog with ajaxButton

[marius d.]

Ok,

Here is what I'm thinking of:

  def ajaxButton(text: NodeSeq, jsFunc: Call, func: () => JsCmd,
attrs: (String, String)*): Elem = {

val params = (name: String) => jsFunc.params ++ List(AnonFunc
(makeAjaxCall(Str(name+"=true"

attrs.foldLeft(fmapFunc(func)(name =>
{text}))(_ % _)
  }


jsFunc impersonates a JavaScript function call. We are appending to
the parameters list specified by the user the actual function that
does the Ajax call.

For exemplification here is a snippet function:

  def button(xml: NodeSeq): NodeSeq = {
  bind("f", xml,
   "show" -> ajaxButton(Text("Press me"), Call("dialog", Str
("a param")), () => {println("pressed"); Noop})
  )
  }

... and here is the JavaScript function declaration:


function dialog(name, theCall) {
alert("Got " + name);
theCall();
}


.. it could be any JS function from a .js file etc.

In this example the actaul Ajax call is made after clicking OK button
of the alert dialog.

Br's,
Marius
