[Lift] Canceling a ActorPing.scheduleAtFixedRate task
Hello, Is there any way to cancel a task created with a ActorPing.scheduleAtFixedRate? From looking at the source (http://scala-tools.org/scaladocs/liftweb/1.0/net/liftweb/util/ActorPing.scala.html) it seem that scheduleAtFixedRate creates an actor which accepts an UnSchedule message. Unfortunately this actor is not returned to the caller. Thanks in advance, Xavi --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Canceling a ActorPing.scheduleAtFixedRate task
There isn't much to show... but maybe an example clarify things.
class SomeCometActor extends CometActor {
override def localSetup() {
ActorPing.scheduleAtFixedRate(this, TaskMessage, 15 seconds, 15 seconds)
}
override def lowPriority = {
case TaskMessage =
DoSomething()
if(someCondition) { /* stop the scheduled task... What do I put here?*/ }
}
}
If scheduleAtFixedRate returned either the Future or the Actor it
creates, then stopping the scheduled task would be fairly straight
forward. Then again, I might be missing something.
Thanks,
Xavi

[Lift] Re: Canceling a ActorPing.scheduleAtFixedRate task
I think I figured out a way to get around this:
class SomeCometActor extends CometActor {
private var tempActor: Actor = null
override def localSetup() {
val cometActor = this
var tempActor = actor{ loop { react {
case TaskMessage = cometActor ! TaskMessage
case UnSchedule = exit
} } }
ActorPing.scheduleAtFixedRate(tempActor, TaskMessage, 15 seconds,
15 seconds)
}
override def lowPriority = {
case TaskMessage =
DoSomething()
if(someCondition) { tempActor ! UnSchedule }
}
}
Instead of registering the comet actors for the scheduled task, I
register a temporary actor. During its execution, scheduleAtFixedRate
creates an actor. Let's call this the Scheduled Task Actor. The
scheduled task actor is then linked(see
http://www.scala-lang.org/docu/files/api/scala/actors/Actor.html#link%28scala.actors.AbstractActor%29)
to the temporary actor i passed in. So now, when I need to stop the
scheduled task actor, I can shutdown the temporary actor. This works
because when an actor is shutdown, all actors it's linked to are shut
down as well.
This is kinda nuts, but I guess it works.
I'm just sharing in case someone else runs into this problem.
Thanks,
Xavi

[Lift] Re: Comet Actors - single browser, multiple tabs, same URL - out of control GET problem
I vaguely remember reading a thread that claimed Lift would auto-increase the 2 connection limit for sessions using more modern browsers. Is this feature in M5? Random Idea: Would it be possible to get around the 2 connection limit by sending each comet request to a unique sub-domain? For example, current lift webapps send comet requests to: http://www.[your-domain].com/comet_request/96624280773/vhbz24xby3vm Could lift instead send comet requests to comet[uniqueId].[your-domain].com/[params]?

We thought maybe we did something wrong in our code, so we tried the same thing using demo.liftweb.net. We saw the same behavior in the demo site that we see in our site. If you try this with something else like Gmail, it does not show this behavior. It's not a bug. There is a 2 connection per server per browser limit (in most browsers although Chrome and FF 3.5 apparently have relaxed this limit). If there is a long polling operation in progress and a second request comes into the same session, Lift will immediately end the long polling operation in order not to starve the connections.

[Lift] Re: Lift deal breakers
If I understand everything correctly, the proposal is to dynamically create a js file for each page request to add event handlers? If this is true, then I'm against the proposal for the following two reasons: 1. Every page will load slower Since the js file is dynamically create on each request, the js file will be un-cacheable. This means the browser be will forced to make an addition HTTP request to the server to render each page. This adds roughly 150ms to the page load time (50ms to 200ms for network lag, 50ms for download, 10ms for js execution). 2. Each page will be more fragile Requiring the synthetic js file will add another point of failure. Even now-a-days with the ubiquity of broadband, connects still get lost and files still get corrupted.

I kinda used the term js file a bit too loosely. It is true that each

page on subsequent load would have different content so the file can

I'm thinking that instead of:
button onclick=liftAjax.lift_ajaxHandler
('F1029758482780OTA=true',null, null, null); return false;Press me/
button
We could have:
button onclick=liftAjax('F1029758482780OTA')Press me/button
...
.. and at the end of the page:
script type=text/javascript
function liftAjax(id) {
liftAjax.lift_ajaxHandler(id + '=true',null, null, null); return
false;
}
...
/script
Likely there will be more synthetic functions that would need to be
generated depending on specific cases. This approach would result in a
slightly larger markup but I'm not sure if the impact is negligible or
not. In essence we are replacing a function call with another one more
concise which helps just in having a more concise function calls in
the markup.
BUT most likely for functions like liftAjax above we should put them
in liftAjax.js that lift generates and those would just be helper
function. This means that the script block above will not be needed
anymore. Thoughts?
Thanks Xavi for the good points.

I started looking through the API and noticed that we have
net.liftweb.util.Scheduled in ActorPing.scala is this what I need?
Anyone have any examples?
thanks..

[Lift] Feature Request: Add S.findComet(theType: String, name: String): Option[CometActor]
Hello,
Would it be possible to add the following findComet override to LiftSession?
def findComet(theType: String, name: String): Option[CometActor] =
synchronized { asyncComponents get (theType, name) } // I'm not sure
if this is the correct implementation, but you get the idea
I'd like to be able to get hold of a specific CometActor without
storing it in a session variable.
Thanks,
Xavi

[Lift] Syntax Highlighting On Wiki
Hello,
I've recently discovered how to add syntax highlighting to the wiki
(http://wiki.github.com/dpp/liftweb).
First, you simply added this to the top of the article:
link
href='http://scala-tools.org/scaladocs/liftweb/1.0/_highlighter/SyntaxHighlighter.css'
rel='stylesheet' type='text/css'/
Next, you added these two lines to the bottom of the page:
script
src='http://scala-tools.org/scaladocs/liftweb/1.0/_highlighter/shAll.js'/script
scriptdp.SyntaxHighlighter.HighlightAll('code');/script
Finally, just surround and code snippets with:
pre name=code class=scala:nocontrolsYour scala code.../pre
FYI: Enabling syntax highlighting on github basically boils down to
importing a JS syntax highlighter into the page. Currently, the wiki
is directly referencing the js highlighter on scala-tools. Is that
okay?
Thanks,
Xavi

[Lift] Re: Question about Lift/Scala Lift Discussion Board
I applaud Artem's initiative! The mailing list has undoubtedly been an extremely helpful resource. That said, a mailing lists in general have several short comings: - Hard to search through - Many duplicate questions - No stickies - No syntax highlighting and few formatting options - Little to no message organization - Few moderation tools A forum could be a nice way to address these issues, so it might be worth a try. Also I think introducing a forum is anymore likely to splinter than an IRC chat room. Just my two cents. -Xavi On Sat, Aug 29, 2009 at 8:22 PM, Timothy Perretttimo...@getintheloop.eu wrote: Agreed (and +1) - Personally I actually prefer mailing lists full stop because it involves no web site trawling to get to the topics one is after...

Hello, I don't quite understand what a more REST orientated approach. Do you mean purely client-side comet actor interface? I personally would love to write javascript like this: lift.comet.MyActor.listeners.add(myListener); lift.comet.MyActor.send(myJSObj); I've been emulating this type of interface by wrapping this.jsonCall (where this refers to a comet actor instance) with javascript function.

[Lift] Re: Google Analytics
Sorry, I didn't replay earlier, but it turns out that the operation
is not supported code: 9 error is related to the fact that the
default Google Analytics snippet uses document.write(). It turns out
that XHTML does not support document.write(), which causes Firefox to
chock.
Ultimately, I replaced the default Google Analytics snippet with this one:
script src=http://www.google-analytics.com/ga.js; type=text/javascript /
script type=text/javascript
//![CDATA[
try { var pageTracker = _gat._getTracker(UA-4384857-1);
pageTracker._trackPageview(); } catch(err) {}
//]]
/script

[Lift] Re: Future of the Lift wiki
That's a great way of putting.

Eventually (1.5+ years) it could even become the lift encyclopedia. Are these worthwhile goals? Please don't view these e-mail as just a bunch of noobs complaining about documentation.

Do note however, that if you really wanted to use your way, then lift would not get in your way Cheers, Tim On May 30, 10:57 pm, valotas valo...@gmail.com wrote: Hi all! Just a proposal: wouldn't be better to have the views look like more an html page. I mean for the basic project created, instead of having an index.html look like lift:surround with=default2 at=content h2Welcome to your project!/h2 plift:helloWorld.howdy //p /lift:surround have something like: html lift:surround with=default2 at=content head titleA better title than the one in default.html/title /head body h2Welcome to your project!/h2 plift:helloWorld.howdy //p /body /lift:surround /html Yes we have more boilerplate code but with that way it would be much more easier the edditing of the page.

[Lift] Error with tictac example
Hello,
There seems to be an error in the tictac on the following line:
registerCleanupFunc(() = is.foreach(who = LobbyServer ! RemoveLurker(who)))
I've changed the code to this:
override protected def onShutdown(session: CleanUpParam) {
is.foreach(who = LobbyServer ! RemoveLurker(who))
}
I'm not sure if this is correct, but it seemed to get rid of the
error. Just wanted to let you-all know.
Thanks,
Xavi

[Lift] Help with PocketChange project
Hello, I've started reading through Exploring Lift and I'm having trouble with running the PocketChange demo.

[Lift] Re: The Lift 1.1 list
+10 for documentation effort. Speaking from the noob perspective, the documentation is the biggest barrier to entry for Lift. Currently there are 3 places to get lift documentation: -Get Started Tutorial -Lift Book -Lift Wiki The first two sources are excellent, but the last one is bit lacking. I think it'd be a big win if we can clean up the wiki. Or, at the very least we should get rid of obsolete articles/code. Also, I feel it would be helpful if all the documentation was in one location, opposed to separated into various in PDFs and webpages. Just adding my two cents.

[Lift] Re: MappedTextarea problem
For the sake of better understanding the internals of lift where is screen.css?

David,
I suggest to leave blueprint as it is and to create your own stylesheet.
Create a directory in the webapps dir and put a new .css file into it. Link
that file into your template .
It should be possible to override the blueprint definitions with something
like:
textarea {
width:300px !important;
}
It's not possible to set columns or rows in css, just the width and height in
px, pt, etc.
Hope that helps,
Joachim
As Tyler suggested, I would like to create my own style sheet for my
webapp. My app is currently using the blueprint CSS boss, but I can't
find the screen.css file anywhere on my computer. Is it being called
from within a jar or war file? I can access it by putting the URL in
my web browser, but then I can't find the directory in windows
explorer. I used firebug and confirmed that I can fix this problem by
altering the css style sheet. How can I create my own and where
should I store it in my project folder?
Thanks,
David

[Lift] Re: JQuery corners
Hello,
The problem seems to be in jquery.corners.js: $('.rounded').corners()
calls changeInput(e) which converts input buttons into a-tags. During
this conversion, the name attribute on the original input button is
lost. I'm not too familiar with the internals of lift, but I'm
guessing this is the source of the error.
Hope this helps.

Hi David, Marius,
Here's a small project that illustrates the issue...
To reproduce,
1) Unzip corners.zip
2) Run mvn jetty:run
3) Go to http://localhost:8080
4) Type something in the text field and click Submit button
= You should see Notice: * You typed: [something] appear
5) Edit src/main/webapp/index.html and uncomment this fragment
!-- UNCOMMENT THIS FRAGMENT TO SEE THE BUG
script type=text/javascript
$(document).ready(function(){
$('.rounded').corners();
});
/script

6) Refresh the page
7) Type something in the text field and click Submit button
= Nothing happens?!?
Hopefully you'll get the same behavior as I do.
