[Lift] Re: Thoughts on file streaming
It is not about dropping Lift, it is about starting to use it. I want it very much but i need to consider all pluses and minuses before we jump in. External server for uploading could be a solution but it will not be in Scala and will require some other tools to be involved. I am still looking for solutions how i can do it with Lift. Frankly out there i do not see anything to replace Scala/Lift.

Will this in some way be able to display any progress of the upload (which, imho, is needed for large uploads).

[Lift] Re: Problem with jQuery/JavaScript and Liftweb because of Doctype
To describe it a little cleaner:
in Safari 4, whenever i try to $('#foo').load('/some.html'), it fails
with "Error: NO_MODIFICATION_ALLOWED_ERR: DOM Exception 7" since the
content-type is text/html+xml.
described here:
http://groups.google.com/group/jquery-en/browse_thread/thread/de95e8adf9c0ffb7
in Firefox there is a similar problem (error up at the first post)
which happens because FF kinda sees an error on the lift-generated
XHTML/XML which is caused because the doctype seems to be strict by
default (i guess).
described here:
http://fitzsimmons.ca/jquery-xhtml-11-strict-and-ns_error_invalid_pointer/
I put up some really simple stuff in 'some.html' with 4 html tags, and
it fails on Safari and on Firefox.
When i try to set the Doctype to transitional, the Browser seems to
ignore it somehow, i guess it's because of the tag that occurs
before the doctype.
Is anyone else here using $("..").load('url') on a lift'ed project?

[Lift] Re: Rendering a View from a Snippet
The use case is the following, i am writing a CMS with lift where the
Admin-Interface is just a JavaScript-jQuery-Overlay. The idea behind
it is, that you don't need a special admin-website, but instead you
can just pop open this overlay and manage everything from there.
Since i wouldn't want to let lift's amazing capabilities of creating
forms go to waste, i wanted to create "subforms" which i can render on
startup and place in the divs.
The idea behind the JS-Admin is, that i don't want people to have to
get off the actual website to change content. Like they should see the
live-changes they do while typing textile in the JS-overlay in the
"background" behind the JS-Window. I have this as proof of concept as
a merb (ruby) application, the customers love everything except the
performance which isn't really for high-traffic sites ;)
Also this concept is thought as a workaround for my other thread
(http://groups.google.com/group/liftweb/browse_thread/thread/
5b09578bf4203618). Because then i wouldn't have to get $('#admin-
foo').load('/api/contents') to work, which fails for different reasons
on different browsers with lift.

[Lift] Re: YA menu question: separate menus
This feature will be very useful for me also. Thanks. However, I would like to be able to show a separate menu for the MegaProtoUser menu items. So it would be great if the MegaProtoUser built in menu items had some default LocGroup set. Or if there was a way to change the LocGroup of a Loc at runtime. Maybe this is possible but I have missed it? George On Jun 30, 9:37 pm, Derek Chen-Becker wrote: > Yes. The error you're getting looks like a version mismatch or some other > dependency issue.

[Lift] Re: [scala] Re: higher-kinded types
Adriaan,
i believe the examples below indicate that Scala's type-checker agrees with
me that your proposed correction for my encoding allows for potential
loosening of "A"-ness. See the example below.
In English, in a monad C over A we don't want to encounter some other type
besides A's. We see the problem when we insist that A's have some property,
like being at least Option'ed.
Best wishes,
--greg
// smallest expression of monad i can find
trait MBrace[C[X] <: MBrace[C,X],A] {
def nest( a : A ) : C[A]
def flatten[T <: C[C[A]]]( bsq : T ) : C[A]
}
// a monad that is a Seq
trait MBraceSeq[C[X] <: MBrace[C,X] with Seq[X],A] extends MBrace[C,A]
// This is fine
abstract class MLink[A]( a : Option[A], na : Option[MLink[A]] ) extends
Seq[A] with MBrace[MLink,A]
// But this is not
//abstract class MLink[A <: Option[_]]( a : Option[A], na : Option[MLink[A]]
) extends Seq[A] with MBrace[MLink,A]
The complaint is exactly in line with my concern:
scala> :6: error: the kinds of the type arguments (MLink,A) do not
conform to the expected kinds of the type parameters (type C,type A) in
trait MBrace.
MLink's type parameters do not match type C's expected parameters: type A's
bounds >: Nothing <: Option[_] are stricter than type X's declared bounds >:
Nothing <: Any
abstract class MLink[A <: Option[_]]( a : Option[A], na :
Option[MLink[A]] ) extends Seq[A] with MBrace[MLink,A]

All,
Am i correct in concluding that the solution in The
Moors-Piessens-Odersky paper only works with collections that have been
clever enough to have used type members rather that type parameters? Or, is
there a trick to making the vast majority of the collections types that are
parametrically typed look as if they have type members? (See example
below.)
Best wishes,

type C <: TypeCtor1

def flatten( bsq : C{type E=C{type E=A}} ) : C{type E=A}

// Now, how to make a version of BraceList since List is parametrically
typed?

[Lift] Re: YA menu question: separate menus
Yes. The error you're getting looks like a version mismatch or some other dependency issue. Can you wipe ~/.m2 and try th build again?

[Lift] Re: Examples of ajaxForm(...)
Thanks, Marius, you answered my unspoken question as to whether the
callbacks registered with regular old form elements from SHtml are
called in the AJAX processing lifecycle. The hidden field piece
(instead of / in addition to a submit button) is what I was missing.

[Lift] Re: Examples of ajaxForm(...)
Imagine that your snippet has a bunch of form elements ... such as:
and your snippet function:
def form(xml: NodeSeq): NodeSeq = {
ajxForm(bind(
"f", xml,
"inputFirstName" ->SHtml.text("", (s) => {//do something here})
"inputLastName" ->SHtml.text("", (s) => {//do something here})
) ++ SHtml.hidden(() => {
// Do processing
}))
}
So to the snippet child nodes we append a hidden element where we have
our processing function. Note that Lift automatically serializes the
form elements as key/value pairs forming a HTTP query string. Hence in
your anonymous function fir the hidden element you can just do
whatever action you want. I actually added the hidden so that when
it's called all functions bound to you form lements were executed.
The other way of working with ajax forms is to actually use jsonForm.
Br's,
Marius

[Lift] Re: grabbing rss or other type of feeds within lift
Personally, I'd use Scala's XML parsing to parse the feed... skip the
external library.
You may also want to look at the ESME code
http://incubator.apache.org/esme/ There's an RSS reader and a Twitter
poller in there. The code is Apache
2.0 license, so you can use it without any license-related concerns.

[Lift] Re: Hudson issue
I edited /etc/security/limits.conf to raise the default ulimit nofiles to 4096. If that's not enough I'll bump it again.

[Lift] JS compression with the Alchim maven plugin?
Hello all, has anyone managed to use the Alchim/YUI JS compressor (referenced in the basic lift archetype) in a project? When I create a blank Lift project and add any kind of JS file in the src/main/webapp (or similar) folder, the compilation (or rather, resource compression goal) fails with the following stack trace: http://pastebin.com/m8de90c4 I have not been able to find any specific LOC in my JS files that could cause this exception, and haven't been able to debug the plugin since I lack the source code (the repository is broken). Has anyone had the same problems, or could someone point me to a project where the plugin works? I would really like to get this working.

[Lift] Re: grabbing rss or other type of feeds within lift
mark,
take a look at: http://is.gd/1iUJN
That should provide you some guidance. I notice from your example your
trying to parse the twitter feed? Perhaps if you want to do something
with twitter you should consider a proper twitter api lib:
http://code.google.com/p/java-twitter/
Cheers, Tim

[Lift] Re: Problem with jQuery/JavaScript and Liftweb because of Doctype
Can you be a bit more specific? Is the whole page missing a doctype? or just your ajax stuff? If you could post both the html output code and the calling scala code in question that would help a lot.

[Lift] Re: can a Snippet call a Snippet?
Can you paste some code? Essentially we support nested snippets so your snippet can simply return a markup containing another snippet and it will be invoked. If you really want to manually invoke a snippet from another snippet and if you are not using StatefulSnippets you can just instantiate the class and call your function and pass it the right NodeSeq.
