hi,
its former method i am using in my app(u mentioned it in last reply).
i have one text box and submit button.
when i click on submit button -
i have to show employee info on my GUI page. (in text box i will

I still don't understand.
Does the user do anything to get the faster table updated or do you want the
faster table pushed from the server when something changes on the server?
If it's the former (the user does something to get the faster table
updated), you want to use ajaxButton... the user clicks on the button and
the server-responds with JavaScript that updates the browser.
If it's the latter (the user does nothing, but the server pushes changes to
the client), see CometActor. You can see an example in the Clock.scala code
in the Lift sites/example project.

Hi,
Thanks for u r quick reply.
Now I am explain my problem in details :
I have normal form with one text box and one submit button.
Also i have 2 table components(these are dynamic tables )..but these
table are out of the from tag.These table only displays information.
Flow of the application:
When i click on submit button.
i am population two Lists .
One list get populated from DB.( Slower)
second list get populated from hard code values (faster)
Now i am populate above 2 tables with these two lists when i click on
submit button.
With the above flow i am able to populate above tables(synchronously).
But now i want to configure Ajax into this so i can get faster
results...(as one List get faster)
while other list can get populated asynchronously.
So when i click on Submit button i will populate one list ..but how
can i populate other list with Ajax...
i tried for following:
i was planning when other table getting render make ajax call with
ajaxInvokebut i wont work...
Please help ...
Thanks in advance

yes i have submit button.
on click event of this i am doing other tasks.
What is the user interface (HTML) element that causes the Ajax update to
happen? What does the user do in order to get the Ajax thing to happen?
ajaxInvoke is a very low level call. If you want to have an Ajax button,
use SHtml.ajaxButton. If you want to have an Ajax form, use
SHtml.ajaxForm.
If you can describe what the user interaction should be, I'll write up
some
example code for you.
above data population for text is not on click submit button.

Giving out put on html page like-

What is this
How can i use Ajax in my application.I want to give asynchronous

(Ajax) for my above html component so it can get show list that i
get
from Db call .
This all happening on submit button click

and could be determined maybe we could exclude that silently from the
serialization operation and add a compile time warning.
I guess we need to dig more into scala compiler plugin system.
1. Isn't there a problem with references _inside_ methods that are
impure/sideeffecting?
s = { Db.myCachedInfoNotInSession foo s }
Regarding member references, a simple check for transient
(sca...@transient == java *transient*) to forcve people to use transient
members for non-serializable state.
But IMHO the serialization problem is a (negative?) sideeffect of Lifts rich
model GUID=Func approach.
Perhpas there is a middle way, a way where we can replicate just enough to
survive a node crash?
That's exactly it. We probably don't need everything that Java
Serialization does. Just enough to make it consistent ... the
dependency graphs that is actually used by the user's function.
Thoughts?

At a first glace Java serialization is needed because of its
awareness
of the reference graph. But in the same time it does not perform
well.
One way might be the byte level instrumentation that would induce
code
to figure out the reference graph and know how to stream-ify it using
a given efficient protocol. But that induces risks and it involves
tons of work. I think would be doable though.
The problem is not really the technology of propagating session
information to other nodes. That's the easiest part, but tough one is
figuring out the low level reference graph and serialization
semantics. This is why JINI, JavaSpaces, JGroups, CORBA, JXTA, you
name it, are unlikely to help solving the fundamental problem.

JavaSpaces is just the specification. There are two implementations

[Lift] Re: JPA blank archetype
Can you please set scala.version dependency to 2.7.5 in pom.xml and re-
attempt.
You can do this by looking for scala.version/ element in the
pom.xml.

[Lift] Re: JPA blank archetype
Hi, Marius...
I don't know what you mean by Are you using master? What I did was use
the Maven archetype to create a basic JPA lift app. Then I changed
directory to the top directory and ran mvn compile. That's it. I got
the errors you see. I didn't do anything else.
I've tried blowing away .m2 and I've tried changing the scala version to
2.7.5 (from 2.7.4). No difference.
Does the basic JPA lift app not compile until you do something else to
it? The blank one worked fine. Can you create and compile the Basic JPA
app on your machine without error? Maybe it's something on my machine,
but everything else is working fine.
The Maven command I used is reproduced below.

Sorry for the false noise, setting lift-core dependency to
version1.1-M4/version instead of version1.1-SNAPSHOT/version
in web/pom.xml quite likely would help better.

NB: I have had created a lift jpa project internally and played with

[Lift] How to create (meta) mapper mixin?
Hi,
I'm trying to create some mixins to be applied to mapper/metamapper
objects to be used when objects are always owned by an account
(ie. a multi tenant db)
The mapper parts works fine:
trait OwnedEntity {
self: BaseMapper =
object account extends MappedLongForeignKey(this.asInstanceOf[MapperType],
Account) {
override def dbColumnName = account_id
override def dbDisplay_? = false
override def defaultValue = Account.currentAccount
}
}
but I can't seem to figure out the correct type bounds to create a
MetaMapper mixin that uses the above. Simple example with just a findMap
that finds all the entities owned by the current account:
trait MetaOwnedEntity[A : OwnedEntity] {
self: A with MetaMapper[A] =
// Find and map all entities owner by current account
def findMap[T](f: MapperType = Box[T]) : List[T] = findMap(By(account,
Account.currentAccount))(f)
}
this fails compilation (1.1-SNAPSHOT), any clues?

Thanks for this example. One difference is that you extend
KeyedMapper. I think it could be nice to avoid this (like what I have
below) to make the user/account mixin independent of the actual mapper
(and to enable several such traits to be mixed in. Not sure what happens
if several traits, each extending KeyedMapper, get mixed in??)
But now my head hurts from trying to figure out the correct type
declaration in MetaMapper to make this happen :-)

[Lift] Comet Chat
Hello lifted, I am playing around with the 50ish line based comet example that dpp has talked about in several talks and that is written more about here: http://m.3wa.com/?p=304 Today I showed this to a friend and it looks like the focus of the input box is lost when an update is received. Does anybody have a clue on how this can be fixed? Is it not possible to just update part of the DOM without having to steal the focus from the input field? -- Bjarte Stien Karlsen Ronatoppen 6a, 4638 Kristiansand 95219547 MSN: m...@ibjarte.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: JPA blank archetype
I'm on a new laptop. I didn't do any git pulls of Lift stuff. I just
installed Scala with the IZ installer and then Maven, then I ran the

Changing the lift-core dependency worked. So the problem is definitely
with 1.1-SNAPSHOT -- at least the one I ended up with.

Chas,
The problem is quite likely with the archetype jar in the scala-tools
repo. Derek is probably looking into it.
Yes, your being confused about the master reference is
understandable :)
Good that it compiles through. For now, you can set the dependencies
to lift-core and lift-jpa to 1.1-M4 and proceed merrily.

Does the basic JPA lift app not compile until you do something else to

Totally agree. The rationale for explicit LiftSerializable would be
just for user defined types. Otherwise user's won't have to use it.
Graphs may also have be cyclic paths ... it shouldn't be too big of a
pain though. Furthermore if a dependency graph path leads say to an IO
reference maybe that's unintentional user code doesn't really use that
but compiler put it for whatever reason. If such cases are possible
and could be determined maybe we could exclude that silently from the
serialization operation and add a compile time warning.
I guess we need to dig more intoscalacompilerpluginsystem.
1. Isn't there a problem with references _inside_ methods that are
impure/sideeffecting?
s = { Db.myCachedInfoNotInSession foo s }
Regarding member references, a simple check for transient
(sca...@transient == java *transient*) to forcve people to use transient
members for non-serializable state.
But IMHO the serialization problem is a (negative?) sideeffect of Lifts rich
model GUID=Func approach.
Perhpas there is a middle way, a way where we can replicate just enough to
survive a node crash?
That's exactly it. We probably don't need everything that Java
Serialization does. Just enough to make it consistent ... the
dependency graphs that is actually used by the user's function.

I think we can do it at runtime in development mode. This is just for data
gathering, not for actual implementation. We just need to calculate whether

[Lift] Re: why ajaxButton not submit the form

Hi
i have form with text box and Submit button(with ajax Submit button)
But when i submit the button form is not submitting so i am not able
to get the value of text box..
onclick function get called...
SHtml.ajaxButton is just that... a button that, when clicked by the user,
performs an ajax call to the server.
Just i want to show text value in response with ajax ...
how can i do this
Use SHtml.ajaxForm:
class Form2 {
def render(xhtml: NodeSeq): NodeSeq = {
var user =
def doAjaxThing(): JsCmd = {
SetHtml(updated,
spanHey Dude... I'm Form2 and the user is {user}/span)
}
SHtml.ajaxForm(
bind(form, xhtml,
user - SHtml.text(user, user = _),
submit - (SHtml.hidden(doAjaxThing _) ++
input type=submit value=Click Me/)
))
}
}
Or, if you use the lift:form tag in your view:
div
Ajax Form v1: br/
lift:form
lift:Form1
User: form:user/ br/
Okay? form:submit/
/lift:Form1
/lift:form
/div
You can do:
class Form1 {
def render(xhtml: NodeSeq): NodeSeq = {
var user =
def doAjaxThing(): JsCmd = {
SetHtml(updated,
spanHey Dude... I'm Form1 and the user is {user}/span)
}
bind(form, xhtml,
user - SHtml.text(user, user = _),
submit - (SHtml.hidden(doAjaxThing _) ++
input type=submit value=Click Me/)
)
}
}
In enclosing running code that demonstrates both.

I think we can do it at runtime in development mode. This is just for data

a given class is serializable once... so we don't have to worry about cyclic

top
of primitives, Calenars, SessionVar/RequestVar etc. If users
need
their own classes to be LiftSerilizable they would have to

LiftSerializable trait.
I think we can do it without explicit traits. I think we just
need to
walk
the graph for everything that's added to the LiftSession and see
where it
leads. Any graph we can walk is something that we can
serialize... even
without Java serialization. Any graph that ends in globals or
some class
that refers to native stuff (e.g., IO), then we're toast.
Totally agree. The rationale for explicit LiftSerializable would be
just for user defined types. Otherwise user's won't have to use it.
Graphs may also have be cyclic paths ... it shouldn't be too big of
a
pain though. Furthermore if a dependency graph path leads say to an
IO
reference maybe that's unintentional user code doesn't really use
that
but compiler put it for whatever reason. If such cases are possible
and could be determined maybe we could exclude that silently from
the
serialization operation and add a compile time warning.
I guess we need to dig more intoscalacompilerpluginsystem.
1. Isn't there a problem with references _inside_ methods that are
impure/sideeffecting?
s = { Db.myCachedInfoNotInSession foo s }
Regarding member references, a simple check for transient
(sca...@transient == java *transient*) to forcve people to use
transient
members for non-serializable state.
But IMHO the serialization problem is a (negative?) sideeffect of
Lifts rich
model GUID=Func approach.
Perhpas there is a middle way, a way where we can replicate just
enough to
survive a node crash?
That's exactly it. We probably don't need everything that Java
Serialization does. Just enough to make it consistent ... the
dependency graphs that is actually used by the user's function.
Thoughts?

The problem is not really the technology of propagating

one is
figuring out the low level reference graph and serialization

Good that it compiles through. For now, you can set the dependencies

Does the user do anything to get the faster table updated or do you want
the
faster table pushed from the server when something changes on the
server?
If it's the former (the user does something to get the faster table
updated), you want to use ajaxButton... the user clicks on the button and
the server-responds with JavaScript that updates the browser.
If it's the latter (the user does nothing, but the server pushes changes
to
the client), see CometActor. You can see an example in the Clock.scala

ajaxInvoke is a very low level call. If you want to have an Ajax

use SHtml.ajaxButton. If you want to have an Ajax form, use
SHtml.ajaxForm.

I think we can do it at runtime in development mode. This is just for

on top
of primitives, Calenars, SessionVar/RequestVar etc. If users
need
their own classes to be LiftSerilizable they would have to
implement
LiftSerializable trait.
I think we can do it without explicit traits. I think we just
need to
walk
the graph for everything that's added to the LiftSession and see
where it
leads. Any graph we can walk is something that we can
serialize... even
without Java serialization. Any graph that ends in globals or
some class
that refers to native stuff (e.g., IO), then we're toast.
Totally agree. The rationale for explicit LiftSerializable would be
just for user defined types. Otherwise user's won't have to use it.
Graphs may also have be cyclic paths ... it shouldn't be too big of
a
pain though. Furthermore if a dependency graph path leads say to an
IO
reference maybe that's unintentional user code doesn't really use
that
but compiler put it for whatever reason. If such cases are possible
and could be determined maybe we could exclude that silently from
the
serialization operation and add a compile time warning.
I guess we need to dig more intoscalacompilerpluginsystem.
1. Isn't there a problem with references _inside_ methods that are
impure/sideeffecting?
s = { Db.myCachedInfoNotInSession foo s }
Regarding member references, a simple check for transient
(sca...@transient == java *transient*) to forcve people to use
transient
members for non-serializable state.
But IMHO the serialization problem is a (negative?) sideeffect of
Lifts rich
model GUID=Func approach.
Perhpas there is a middle way, a way where we can replicate just
enough to
survive a node crash?
That's exactly it. We probably don't need everything that Java
Serialization does. Just enough to make it consistent ... the
dependency graphs that is actually used by the user's function.
Thoughts?

it using

involves
tons of work. I think would be doable though.
The problem is not really the technology of propagating

tough one is
figuring out the low level reference graph and serialization

[Lift] id selectors discouraged?
Lifted, At the pixillion master http://github.com/leithaus/pixillion/tree/masteri've an example where it appears that id selectors are not working correctly... Or, maybe i just don't know how to use CSS. The site map (after login) will show three pages of interest: paint, chat, combo. Paint is raw js without lift intervention and works as intended (for now). Chat is cribbed from the lift chat example. Combo attempts to put the two on the same page with lift tags in the drivers seat. As you can see the style is not being governed in the same way on the combo page, causing erroneous behavior in the paint rendering. Any help would be greatly appreciated. Best wishes, --greg -- L.G.

[Lift] multiselect example in Liftbook problem
There seems to be a problem with SHtml.multiSelect following the example in the Lift book (Listing 4.10: Using multiselect). The example shows the last parameter to be a List, while the source for multiSelect shows it to be (String) = Any. When I tried to implement in my own code, I get the compiler error: type mismatch found; List[String], required: String. The book example even states that the function takes a String representing a Category’s primary key and returns the category. The example goes further to explain: We then use this helper method to update the Set that we created earlier. Note that the callback function will be executed for each selected item in the multiselect, which is why the callback takes a String argument instead of a Set[String]. But where is this callback function? Is it the same helper mentioned earlier. There's no other callback function parameter on the multiSelect constructor. This is all very confusing.

[Lift] Re-factored Archetypes
Guys, As promised, i've re-factored the archetypes (now in their own submodule and building as part of master) however their maven group and artifactId's are the same, so all commands etc will continue to work (its purely a code base organization change) Moreover, i've fixed the various issues with velocity in the jpa-basic archetype (its late here, i'll fix the others 2mro) and i've also fixed the Jetty version in all the pom.xml to a sensible range.

cribbed from the lift chat example. Combo attempts to put the two on the

not being governed in the same way on the combo page, causing erroneous

If you remove the:
lift:CSS.blueprint /
lift:CSS.fancyType /
lines from /templates-hidden/default.html, you'll get a much better result.
The CSS in Blueprint CSS is munging the CSS used by the paint program.
Please take a look at Firebug... it's a debugger for browsers... you can see
exactly how the browser applies style to each element. It's mighty helpful.
On other notes, any JavaScript on the page *must* be escaped in ![CDATA[

script type=text/javascript
$(document).ready(function() {
/script
becomes:
script type=text/javascript

The change set I sent out the last time you used the pixillion stuff as an

I'm not sure I would change how snippets are dispatched based on run mode or

Use traits to describe the pieces of your business logic rather than
classes. Traits can be composed very easily.
Don't use new, but use object's as factories that make run-time
decisions
about how to compose traits and vend them.

[Lift] Mapper with custom id
I'm trying to import data from a non-mapper-based database to one that is. I'm reading data with DB.exec and trying to save it using Mapper, but it's not getting saved. I'm guessing that since I'm setting the id (in runSafe) it thinks it needs to do an update, not an insert. Is there a workaround? Also, doesn't this scenario break the logic of MetaMapper.saved_?() ? Wouldn't it make more sense to have a saved flag that is cleared by default and set when it's created as a result of a find, and after it's saved? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

ajaxCall returns a tuple of (String, JsExp). I'm not sure why the compiler
is letting that get converted into the second half of a pair for
UnparsedAttribute purposes... but... in order to use it, you must do:
ajaxCall(JsRaw($('#whoField').attr('value')), s =updateWho(s))._2
But... it'd be better to ValById:
ajaxCall(ValById(whoField), , s =updateWho(s))._2
I've added a few helpers to ajaxButton, so you can do:
submit - ajaxButton(Text(?(Send)), ValById(whoField), s =
updateWho(s))
who - whoNode(world)
