[Lift] Re: Exception for S.? while booting
I'm aware about the override thing but I don't see why you would do it
in such way. Since you don't have state, you don't have a session =
you don't have S. Are you using a statelesDispatchPf ?
You can do:
1. Use your own ResourceBundles
2. Or a hacky thingy like:
val session = LiftRules.getLiftSession(request, httpRequest)
S.initIfUninitted(session) {
// Now you should be able to call call S.?(...)
}
Localization is bound to state as ResourceBundles
You exception thrown in Boot probably was cause because you used a val
and it obviously tried to initialize it. Using a def or lazy val it
would be evaluated properly upon requests.
Typically S.? is used in the context of page rendering, Ajax functions
processing, DispatchPF. All these are executed in a stateful context
where S is available. To process pure stateless requests you have
LiftRules.statelessDispatchTable, and a few request processing
hooks ... but do you really need those?
Do you have a usecase when you want to process a pure stateless
requests and need Lift's localization?

By default there will be the servlet implementation and it'll work as currently. 3. Certain function names will slightly change. 4. If your application explicitly wants to use HttpServletRequest obtained from S some explicit casts would be needed.

[Lift] Re: Title function
The snippet itself can bind the title if it has the head inside it. Something like: lift:surround at=content lift:MySnippet.method head titlemysnippet:title //title /head ... /lift:MySnippet.method /lift:surround This is what I do (with no title element in the default template).

I don't know if originally I had it in default using lift:Menu.title or not, but the difficulty with that would be that some pages can be used to edit or add a new item, and the title needs to reflect that. So either (1) I need a way that the value of Menu.title will depend on data in various StatefulSnippets; or (2) make the title ambiguous (add/edit neutral); or (3) leave the titles in the views and process them with a function somehow; or (4) put a snippet in the title of every view to get the user. - David Pollakfeeder.of.the.be...@gmail.com wrote: On Sun, Aug 2, 2009 at 4:35 PM, Naftoli Gugenheim naftoli...@gmail.com wrote: How does the Title LocParam work?

[Lift] Re: jQuery - esp. datepicker
1) yes. That's why I would suggest using a class instead if you have multiple date fields. We just used an id in this case because there was only one date field on the page. 2) I agree. I don't know why you were getting that error :( Lift has jquery bundled with it. You should be able to include it on a page by adding head script id=jquery src=/classpath/jquery.js type=text/javascript/ /head to your pages ( or to your default template). Is that how you had it set up when you got the error? The jquery.js file is pulled from /lift/src/main/resources/toserve under the project root, which will put it in the lift-webkit.jar file. Currently it's 1.3.2. Sorry, I had missed that part of your original question.

[Lift] Re: Using ExtJS with Lift?
Your guess is correct. The jquery-ui-min.js contains the datePicker. We used
to use datePicker.js but then we switched to the datePicker that's in jquery
UI.
As for your question about where to put the scripts, you don't want to put
them in src/main/resources/toserve unless you're writing a widget or some
other programmatic user of the scripts. If you'll just be using the scripts
directly in your templates you can just put them in the normal
src/main/webapp tree (I usually make a scripts subdir to segregate things).
Let me know if that doesn't work or if I'm misunderstanding the question.

(1) Searching in directory C:\www\work\PocketChange\ (I'm currently

jquery.datePicker.js

OK, so on re-read I totally misunderstood the question :P. If you write your

ResourceServer). No need to hack on the lift module itself.

[Lift] Re: Converting from HTML form values to numeric MappedFields
I think that you'll need to provide your own _toForm method on the field.
Fortunately, it's a pretty trivial method (from MappedField.scala):
1. /**
2.* Create an input field for the item
3.*/
4. override def _toForm: Box[NodeSeq] =
5. S.fmapFunc({s: List[String] = this.setFromAny(s)}){funcName =
6. Full(input type='text' id={fieldId}
7. name={funcName} lift:gc={funcName}
8. value={is match {case null = case s = s.toString}}/)
9. }

[Lift] Re: Mega*ProtoUser extensibility - a suggestion.
David,
First apologies for accidently taking this thread off the lift group.
It was entirely accidental.
So my question with regards to the scala language that I can't seem to
find an answer for online anywhere is what exactly is an object nested
inside a class i.e. :
class ObjectWrapper {
object obj extends AnyRef{var prop = prop}
}
versus a class with a final val that's set to an instance of an
anonymous class i.e. :
class AnonClassWrapper{
final val obj = new AnyRef{var prop=prop}
}
I've tried to discover some sort of behavioral difference both in
simple tests in the scala console, and couldn't find any. In both
clases obj responds just as if it was a val and not a type. This
analogy towards static classes in java breaks down because a static
class in java is one that doesn't have a containing instance, and yet:
scala class ObjectWrapper{var outerProp = prop; object obj extends
AnyRef{var prop=outerProp}}
defined class ObjectWrapper
lastly, in a desperate attempt to prove to myself that there is an
actual difference I went against your rule and changed a RequestVar
from an object extending RequestVar to a value set to an instance of
an anonymous extention and my lift app ran without any changes in
behavior???

In this case, if you change the type/behavior of the SessionVar and/or
RequestVar, you could mess up code that depends on these.
You also must *always* make RequestVar and SessionVar as object rather than
val so that they can make the determination of their unique string ID.
I view ProtoUser much like I view Rails' scaffolding... at some point the
code becomes too heavy to keep subclassing and it's easier to copy the
MegaProtoUser code into your own User class and go from there.

I have extended Mega*ProtoUser to achieve cookie-based perpetual
login.. and it was fairly easy to do except I ended up having to do
something hackish simply because there are two private object members
in the class that are core to the functionality I've extended.
Namely:
private object curUserId extends SessionVar[Box[String]](Empty)
private object curUser extends RequestVar[Box[ModelType]]
(currentUserId.flatMap(id = getSingleton.find(id)))
I have no idea if this would be an acceptable change, but at least for
one user of lift it would make much more sense that in the spirit of
*ProtoUser's clear intent for extensibility that these members simply
become:
protected val curUserId = new SessionVar[Box[String]](Empty){}
protected val curUser = new RequestVar[Box[ModelType]]
(currentUserId.flatMap(id = getSingleton.find(id))){}
Unless I'm not properly understanding what object members actually
are? I'm interpreting them as being final vals assigned to instances
of anonymous classes (rough tests in the scala console seem to verify
this)

actually that example doesn't work in Opera, but does in safari and
firefox. To see the problem in safari I had to modify the script like
this:
var geocoder = new GClientGeocoder();
geocoder.getLatLng(london,doit);
function doit(point) {
var s = JSON.stringify(point);
alert(s)
}
This does work in Firefox though, but my full version doesn't.
Hopefully these examples will help a little. I am beginning to think I
should just pass simple objects to the server via JSON.

[Lift] Re: Prepare StatefulSnippet in advance
Create a top-level RequestVar:
object TheClient extends RequestVar[Box[Client]](Empty)
object ReturnToMe extends RequestVar[Box[() = Unit]](Empty)
class ClientEditor extends StatefulSnippet {
val referer = S.referer openOr /
val client = TheClient.is openOr {S.error(client not provided);
S.redirectTo(referer)}
val goBackFunc = ReturnToMe.is
... stuff here
when done:
goBackFunc.map(_.apply())
S.redirectTo(referer)
}
So, your link to this page will contain a function that looks like:
{TheClient(Full(client)); ReturnToMe(Full({S.redirecTo(the from page, () =
{re-associate your stateful snippet})}))}

[Lift] Comet render and jQuery
I am might be going about this in the wrong way but I wanted to get
confirmation.
I have a comet lift snippet that waits for a comet actor to send down
search results triggered by a button click after entering keywords.
lift:comet type=SearchActor
Search:SearchResultsLoading.../
Search:SearchResults
/lift:comet
In the actor I rendor the search results and merge an onclick function
into the header document.ready. Things seem to work fine but after
the snippet renders the onclick function does not activate until I
click on 2 hyperlinks, which takes me to the linked website (click
url) then hitting the back button back to the liftwebsite, basically
reloading the page twice. After this the alert box shows up for each
hyperlink.
I can refactor this to work in a different way but I wanted to
understand what is wrong here if anyone knows.
Thanks in advance
def render = {
def searchResultFormatter(itemToFormat: SearchResultSet): NodeSeq
= {
tr
td
a href={itemToFormat.resultSetItem.clickUrl} class=searchlink
{itemToFormat.resultSetItem.title}/a
/td
/tr
tr
td{itemToFormat.resultSetItem.summary}/td
/tr
}
bind(SearchResults - table{searchLinks.flatMap
(resultFormatter _)}/table
head
script type=text/javascript charset=utf-8{Unparsed
(
jQuery(document).ready(function() {
$('.searchlink').click(function() {
alert('call made it here');
return (false);

[Lift] Re: Code review for some Mailer enhancements
Spencer,
I've taken your suggestions and rolled them into Lift... see the enclosed
diff.
Thanks for making the suggestion.
David
On Wed, Jul 8, 2009 at 3:29 PM, Spencer Uresk sur...@gmail.com wrote:
As I alluded to in another email, the way Lift's Mailer class works
causes some problems when deploying to Tomcat (or any environment
where you have multiple applications) due to it relying on System
properties for most of the configuration. As I'm still trying to wrap
my head around both Lift and Scala, I thought it would be a fun
exercise to try and enhance Mailer to allow more flexible configuration.
If anyone has a few minutes, I'd appreciate a review of my code and
the approach I took. If it is good and useful enough, I hope you'll
consider accepting a patch to add these features back into Lift.
So, the idea I had was to allow configuration via JNDI or via a simple
property map. The session lookup function would first try to get a
session via JNDI, if that doesn't work, it will look to see if there
are custom properties to set, otherwise it just uses the default
system properties (which is how it works now).
One feature I added that I'm not 100% sure about is if there is an
exception when looking up the JNDI reference, it swallows the
exception and returns Empty so that custom/default properties can be
used. This would allow you to use JNDI in production, but a simple
property map in development. This is a nice convenience feature, but
it could potentially hide production errors (although the exception is
logged).
Here are the pieces of Mailer I changed/addded:
var authenticator: Box[Authenticator] = Empty
var jndiName: Box[String] = Empty
var customProperties: Box[Map[String, String]] = Empty
private def getJndiSession: Box[Session] = jndiName match {
case Full(jndiSessionName) =
var session: Box[Session] = Empty
try {
val context: Context = new InitialContext().lookup(java:comp/
env).asInstanceOf[Context];
session =
Full(context.lookup(jndiSessionName).asInstanceOf[Session])
} catch {
case e: Exception = Log.error(Cannot lookup session from
JNDI, e)
}
session
case _ = Empty
}
def session: Session = {
val session = getJndiSession match {
case Full(jndiSession) = jndiSession
case _ = authenticator match {
case Full(a) = Session.getInstance(buildProps, a)
case _ = Session.getInstance(buildProps)
}
}
session
}
def buildProps: Properties = {
val p = System.getProperties.clone.asInstanceOf[Properties]
customProperties match {
case Full(customProperties) =
{customProperties.keys.foreach{key = p.put(key,
customProperties(key))}}
case _ =
}
p
}
===
And here is how you would configure the mailer in your Boot class:
// Using custom properties
val mailProps: Map[String, String] = Map(mail.smtp.starttls.enable -
true, mail.smtp.host - smtp.gmail.com, mail.smtp.auth -
true, mail.smtp.port - 587)
SuperMailer.customProperties = Full(mailProps)
// Using JNDI
SuperMailer.jndiName = mail/Session
===
I still need to do a little more testing, but everything seems to be
working ok. I'd appreciate any feedback on the code.
Thanks,
- Spencer

I'm aware about the override thing but I don't see why you would do it
in such way. Since you don't have state, you don't have a session =
you don't have S. Are you using a statelesDispatchPf ?
You can do:
1. Use your own ResourceBundles
2. Or a hacky thingy like:
val session = LiftRules.getLiftSession(request, httpRequest)
S.initIfUninitted(session) {
// Now you should be able to call call S.?(...)
}
Localization is bound to state as ResourceBundles
You exception thrown in Boot probably was cause because you used a val
and it obviously tried to initialize it. Using a def or lazy val it
would be evaluated properly upon requests.
Typically S.? is used in the context of page rendering, Ajax functions
processing, DispatchPF. All these are executed in a stateful context
where S is available. To process pure stateless requests you have
LiftRules.statelessDispatchTable, and a few request processing
hooks ... but do you really need those?
Do you have a usecase when you want to process a pure stateless
requests and need Lift's localization?

Marius

I thought validations is a function not a val:
override val validations should probably be
override def validations ?

override lazy val validations ?

Thanks for looking into it... OK, you have two problem here (which are Scala IDE bugs, so I was a bit harsh on Maven this time around). You have two output folders: the Scala IDE = 2.7.5.final only supports one. Use a single default output folder. You also have source directories nested below the top level of your project. Although I've seen reports that this works from various people, there's code in 2.7.5.final and earlier which makes this unlikely. If switching to a single output folder doesn't solve your problems try also moving your source directories to the top level. Both of these issues are fixed on trunk (but don't go there unless you're using the Lift 2.8.0 branch). Let me know how you get on ...

[Lift] Re: New features
First of all, let me tell you what the error means. It means that there is a
relevant row in the join table that doesn't have a corresponding element in the
other table. Specifically, calling joinRecord.childMappedForeignKey.obj, so to
speak, returns Empty.
The question is how it got to this inconsistent state. When you add a Role to a
User, MappedManyToMany creates a UserRole for it. For some reason though there
is a UserRole without a Role or User.
Can you send me a self-contained project? Also is it high priority?

Oh, I think I know what the problem is. I think I should classify it as a bug.
Since you're adding a Role that isn't saved yet, and ManyToMany tracks the

the Role before adding it, although the need to do so is against the idea of
ManyToMany and OneToMany. I will see what I can do, G-d willing.

addRole,
submit - SHtml.submit(S?(Save), ()=view.save)

The offending code seems to be the line: roles -
theUser.roles.flatMap{
in the above bind method when I click on the addRole link.
Here's my User class:
class User extends MegaProtoUser[User] with ManyToMany[Long,User]{
def getSingleton = User // what's the meta server
object roles
extends MappedManyToMany(UserRole, UserRole.user, UserRole.role,

}
What am I doing wrong? You can see how difficult it is to slog through
this code, let alone just
trying to explain the problem so I can get help.

By the way, as per my correction, you can implement list the regular way
without ModelView, and just use ModelSnippet's load function in your edit

I fixed my code per your comments and now I can edit and remove users
from a list, as long as I populate the list with
ModelView instances, as you said. As for the docs, this step was not
clear to me at all. I just assumed that the list was
just populated with User entities and the view in the ModelSnippet was
instantiated with the selected User on each request.
It sounds like your plate is pretty full, so I won't expect much, but
sometime soon, could you provide an example, or improved
docs, for using TableEditor and its related ItemsList trait.
Thanks for all.

The only way to really know what's going on is to meticulously trace

[Lift] Alternate part of view
What's the smartest / most concise way to achieve the following in the corresponding view xhtml and snippet code: Parts of the view have to change, depending on whether something is set. For example, in the area where you select the client, if the client is None, then it displays an interface to select a client. If it's set to a Some then it displays the client's details with a button to unset it. This pattern is repeated. My current strategy is to have two elements, req:noClient and req:client, which have different xhtml contents. Then in the snippet I bind them to two NodeSeq functions, one that binds useful contents when the client is None and returns NodeSeq.Empty otherwise; and another function that binds when it's a Some and returns Empty otherwise. However, it seems to be somewhat redundant in theory. So does anyone have a better way of switching view parts?

[Lift] Re: Exception for S.? while booting
No really. That is for constructing an S object, as it needs the
reuest and session object. Lift calls that when processing statefull
requests and rendering pieline, bound functions etc. are executed in
this context. There is another function S.initIfUninitted where S can
be initialized having only the session and no request. This is used by
Lift inside Comet actors.
Typically applications should not care about this.

I'm aware about the override thing but I don't see why you would do it
in such way. Since you don't have state, you don't have a session =
you don't have S. Are you using a statelesDispatchPf ?
You can do:
1. Use your own ResourceBundles
2. Or a hacky thingy like:
val session = LiftRules.getLiftSession(request, httpRequest)
S.initIfUninitted(session) {
// Now you should be able to call call S.?(...)
}
Localization is bound to state as ResourceBundles
You exception thrown in Boot probably was cause because you used a val
and it obviously tried to initialize it. Using a def or lazy val it
would be evaluated properly upon requests.
Typically S.? is used in the context of page rendering, Ajax functions
processing, DispatchPF. All these are executed in a stateful context
where S is available. To process pure stateless requests you have
LiftRules.statelessDispatchTable, and a few request processing
hooks ... but do you really need those?
Do you have a usecase when you want to process a pure stateless
requests and need Lift's localization?

I thought validations is a function not a val:

override lazy val validations ?
