[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.

[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: New features
Building causes a stack overflow?
So the question is, is it the resident compiler or plain scalac also crashes?
Or just the presentation compiler? What do you see in the error log view or
file?
I get compiler crashes very often when doing fancy mapper type related tricks.

Naftoli,
While your working on this issue, there seems to be another. Here's
what's happening:
If I make a coding mistake, and code User as follows:
class User extends MegaProtoUser[User] with ManyToMany[Long,Role]{
def getSingleton = User // what's the "meta" server
object roles
extends MappedManyToMany(UserRole, UserRole.user, UserRole.role,
Role)
}
instead of
class User extends MegaProtoUser[User] with ManyToMany[LongUser]{ ...
I don't get a compiler error (I'm using Eclipse with the Scala
plugin). Instead,
I get a stack overflow error and my IDE crashes.

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
children via the join table, it can't access the child. As a workaround save
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.

[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?

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 ...

No. Each template must be xml well formed so you can not have more then one root element, Please see to handle multiple binds.

[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.
Loading...
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

[Lift] Re: Prepare StatefulSnippet in advance
I don't have code available to post right now, but let me try to explain better. Basically you're editing a request, which is associated with a client. Now when your entering the request you may notice that the client's info is wrong. So I need a link to the client editing page, which is StatefulSnippet based. However, when that page loads it has to use an instance of the snippet that knows which client I want to edit. - David Pollak wrote: Please provide a complete (executable) code sample so I can understand the flow.

[Lift] Re: Mega*ProtoUser extensibility - a suggestion.
There was a time when:
class Foo {
def bar = "Hello"
}
object Moose {
object foo1 extends Foo {
def baz = "Howdy"
}
val foo2 = new Foo {
def baz = "From another foo"
}
}
println(Moose.foo1.baz)
println(Moose.foo2.baz)
Would not compile because the type of foo2 was Foo, not some subclass of
Foo.
I guess you could use a lazy val in place of an object and change its
implementation in the subclass (although it was rumored that a 2.8 feature
was the ability to change the implementation of an object in a subclass, but
I'm not sure it's going to make it in.)
But, at the end of the day, if you need that much customization of
ProtoUser, copy/paste the code and deal with your own implementation. :-)

In order to debug the problem, I need something that is fully running (e.g.,
fork http://github.com/dpp/lift_1_1_sample/tree/master and implement
something that demonstrates the problem).
The mechanism we are working on is passing the objects to the server via
JSON. JSON.stringify is the JSON serializer and an JavaScript object must
be serialized to send to the server.

[Lift] Re: Asynchronous Javascript problem
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: 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???

[Lift] Re: Title function
You mean the snippet should put its new/edit flag somewhere that the Title can read, like a top level object? Then it doesn't need to be an AnyVar because it can be set on every request, if Title is processed after the snippet in each request--and if not then I don't see how a RequestVar etc. would work. Seems like it may be more work than the other way, though. By the way I sent corrected message afterward--my question was not about LocParams but of the items of type ParamType. - Derek Chen-Becker wrote: If you're just looking for a way to programmatically set the title, getting into LocParam might be a little bit of overkill.

[Lift] Re: New features
I'll try.
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 link
or button, passing it the User instance.

It sounds like your plate is pretty full, so I won't expect much, but

In the link I specify a function that instantiates and registers an instance of that StatefulSnippet. However the page does not use that instance but a new instance instead. What am I doing wrong? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: New features
Correction: ModelSnippet.load takes the actual Mapper instance, not the
ModelView wrapper.

To answer your immediate question, the listing should not refer to the
snippet's view but new ModelView instances for each entity. Then editAction is
shorthand for the snippet's link method with a callback to call load on the
ModelView. To set the snippet's view's entity, either call load on the snippet
with the other ModelView, or call load on the other ModelView (or just set its
entity directly).
As far as documentation, please tell me what scaladocs need what clarification.
Thanks.

Naftoli,
Functional programming systems are notoriously difficult to document.
The only way to really know what's going on is to meticulously trace
through the source. But that requires
time-consuming trial and error coding. So, without clear examples
demonstrating exactly what you have in mind, I and others in the same
boat, could spend days and still not
get it right.
For example, I tried this:
var theUser:User = null
val view = new ModelView(theUser, this)
def list(ns: NodeSeq): NodeSeq = User.currentUser.map({user =>
User.findAll.flatMap({u =>
bind("user", chooseTemplate("user", "entry", ns),
"firstname" -> Text(u.firstName.is),
"lastname" -> Text(u.lastName.is),
"email" -> Text(u.email.is),
"roles" -> u.roles.map(_.name.toString).mkString(",
"),
view.editAction,
view.removeAction
)
})
}) openOr Text("You're not logged in")
and, I get a null value exception when I try to remove a user in the
list. Simply using
val view = new ModelView(new User, this), doesn't work either,
although I don't get an
exception. Now, where should I be calling load in all of this?

[Lift] Loc.title impl redundancy?
Why does title: NodeSeq try linkText if title(in:ParamType) calls linkText(in)? Is it possible that (forceParam or foundParam.is or defaultParams) will evaluate differently by that time? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: Asynchronous Javascript problem
ok, lots of jscript debugging and I'm pretty sure its this: JSON.stringify(new GLatLng(0,0)) where GLatLng is a google map object. the imports needed for this are http://maps.google.com/maps? file=api&v=2.x&key=your-key&sensor=false" type="text/ javascript"> there is a key=your-key argument in that first import. don't worry about that, just make sure you test the page using localhost, not 127.0.0.1, just localhost.
