[Lift] Is there a Order Map in the lift ?
Hi all, Is there a Order Map in the lift ? Example: 1-> "xx", 2 -> "yy", 3 -> "zz" 1:) add 1-> "xx" Map(1-> "xx") 2:) add 3 -> "zz" Map(3 -> "zz", 1-> "xx") 3:) add 2 -> "yy" Map(2 -> "yy", 3 -> "zz", 1-> "xx") The result maybe: Map(2 -> "yy", 3 -> "zz", 1-> "xx") But i want the structure(order by the number) is : Map(1-> "xx", 2 -> "yy", 3 -> "zz") Any help would be much appreciated !

[Lift] Re: CometActor and render
Thanks David. This is a big help. Can you tell me exactly how lowPriority,
mediumPriorty and highPriority work? When are they called?

I use JRebel and SBT (http://code.google.com/p/simple-build-tool/) and very rarely have to restart my server when doing development. It's a very quick dev-cycle. No big tips really.

[Lift] How quick is webdev with Lift?
How quick is webdev with Lift? Is your Lift dev-cycle of webapp is the same as with classic Java? I mean these steps: 1) code 2) compile 3) deploy 4) find error ... n-2) re-compile n-1) re-deploy ... Such as Scala is compilable lang, every change made into the snippets requires "re-compile" and "re-deploy". This slows down development. Are you using JRebel (formerly JavaRebel)? I have used this lib for Java projects and it worked fine. Are there any other tips to speed up webdev on JVM-Scala-Lift compared to JVM-Java-XXX? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: CometActor and render
Jack,
I reproduced your code and it seems to work fine. I've enclosed a working
copy.
Some comments about your code:
- The foos variable and the foo variable may be getting confused in the
code... the render method may be rendering the same thing based on the
unchanging foos variable.
- Doing null testing is a sign that you have logic errors in your code.
I strongly recommend using either Box or Option for everything that can
logically not contain a value/reference. If you're bridging out to Java
code and are expecting null from the Java code, write a small bridge that
will wrapper the Java return values in Box/Option.
- You have a case class (Tick) that contains no parameters. Please use a
case object instead.
- Your Tick look is a spin loop. You fire a Tick message as part of
processing the Tick message. I would suggest that if you're polling, that
you have a reasonable poll interval, otherwise you'll starve your CPU.
Further, having reRender on each loop through means that you're forcing a
lot of bytes over the wire rather than only doing a reRender on changed
values.
Thanks,
David

[Lift] Re: jetty/actors performance question tangentially related to lift
Thanks for the feedback David... I have also created a pool of actors and dispatch requests round-robin style to it. Oddly enough, I see absolutely no difference in the performance characteristics - in both cases 95% of the time is spent between the suspend and the actor receiving the request, but the mailbox never grows past a size of 1 or 2. I will try and send along a simplified version of my code to illustrate what I'm doing.

No. A Mapper corresponds to a row in your table. A MetaMapper corresponds

[Lift] Re: jetty/actors performance question tangentially related to lift
If you have all your requests going to 1 actor, then you've reduced your application to a single threaded app. If you're using Scala Actors, there are all kinds of wacky things that happen with the Fork-Join library that the Actors use for scheduling and a whole lot of knobs to turn to get the scheduling right depending on your number of CPUs, etc. But, at the end of the day, if you're just pushing work from one thread (the thread that the HTTP request comes in on) to another thread (the thread that's waiting for the RDBMS request), you're not saving any time or threads, in fact you're only increasing the amount of thrash between scheduling the Actor, suspending the HTTP request thread, etc. But, without seeing your code, it's hard to give you a better analysis.

[Lift] Re: How to bind the Map to View in the Snippet ?
How should i write the bind code ?
var data = Map(2009/10/09 -> List(St1), 2009/10/10 -> List(Hello, M7,
123,da))
data.flatMap(d=> {
Log.info(" *:" + d)
bind("data", in,
"date_title" -> Text("222")
)
})
Get this erors:
found : Iterable[scala.xml.Node]
required: scala.xml.NodeSeq
data.flatMap(d=> {
I'm not familiar with this.
I want the page show like this:
date - 2009/10/09
st1
date - 2009/10/10
Hello
M7
123
da

[Lift] Re: How to bind the Map to View in the Snippet ?
That should not be foreach but flatMap.
Foreach is like map but returns Unit, and flatMap is like map but it
concatenates the resulting elements, which must be iterable (or iterators,
depending).

[Lift] jetty/actors performance question tangentially related to lift
Hi, Currently I have a jetty webapp that uses continuations and actors to scale to many connections. While this isn't a lift question per se I was hoping the folks on this list could help since it's my understanding that Lift does similar stuff under certain setups. Basically, the functionality that I'm testing receives a request, suspends it via jetty continuations, and fires it off to an actor for processing. Once the work is done (some benchmark database requests, usually on the order of 10 to 100ms) the continuation is resumed and results are returned. As I scale up to 1000+ concurrents in apache benchmark, I notice that the vast majority of time from receipt of the request to response, is between when the continuation is suspended and when my actor receives the message. This strikes me as bizarre since I'm monitoring the mailbox and it never grows to a size larger than 1 or 2. It gets to the point where requests are taking 10 seconds to come back and 9.5 of those seconds are my actor waiting to receive the work request. Throughout the load test the database does not become stressed. Any thoughts on this? I guess I'm hoping there is something basic that I'm doing wrong. Just in case, I've tried creating an actor pool to receive the work requests but that apparently has no effect on the results. My only speculation at this point is that perhaps the reason messages are taking so long to get to my actor is because jetty itself is overloaded trying to queue requests but that is just a guess.

[Lift] Re: CometActor and render
Sorry. Here it is: As I said, I know that when render is called,
foo.getValue has the right value. But it does not show on the screen, unless
I refresh the browser.

Set transient mark mode (from options menu), then M-SPC (ESC then space, or alt+space) to set mark and move around with cursor. Then M-w (ESC then w, or alt+w) to copy region, C-w (ctrl+w) to kill (cut) region. -Ross On Nov 8, 2009, at 10:08 AM, Marius wrote: > > Do you guys know how to select text just with keyboard in emacs? > Something similar with SHIFT + down-arrow etc. > > Br's, > Marius > > On Nov 8, 10:40 am, Marius wrote: >> You guys are right.

Yes, it just did the trick. It compiles now.
Why is it working now? Isn't it Mapper also a MetaMapper?

[Lift] MegaProtoUser + MappedPassword question
I'm using MegaProtoUser which has a MappedPassword field. When the sign up form is displayed, the password field is pre- populated to '***' which is proving very confusing for some users. I would like to display the password field as a completely empty field, but I can not see a way to override this behavior. MegaProtoUser is mostly suiting my needs pretty well right now, so I am reluctant to roll my own for the sake of such a small detail. Does anyone have any ideas how I can achieve this? thanks george --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Re: Select multiple values
Allright. This code does the trick:
bind("e", xhtml,
"name" -> text("", name = _),
"availableManagers"-> SHtml.multiSelect(
User.findAvailableManagers.map(v =>
(v.id.toString, v.email)),
Nil,
_.foreach { id => loadManager(id)},
"multiple" -> "multiple",
"title" -> "Click to assign managers to this
fund"),
"submit" -> SHtml.submit( "Submit Form" /*button name*/,
processForm /*function to call*/))
So what did I change? SHtml.selectObj[User] to SHtml.multiSelect and
also the function executed after submit since a List[String] is now
passed to it.
Any comments?

[Lift] Working with database views
Hello guys,
I need to create a database view to create a very specific query from
an API. I am planning the following steps:
1. Create the view in the database directly
2. Create a model without a primary key extending Mapper instead of
Keymapper
3. I am not going to add the view to Schemifier since I am managing
the creation and maintenance of the object manually
My problem is that I am having problems to compile the Mapper class.
This is the code I am trying to create:
class SyncVW extends Mapper[SyncVW] {
def getSingleton = SyncVW
object field1 extends MappedLong(this, ContentSource)
object field2 extends MappedString(this, 999)
object field3 extends MappedString(this,255)
object field4 extends MappedString(this,30)
}
object SyncVW extends SyncVW with Mapper[SyncVW]
The compilation error is in the "def getSingleton" line. The compiler
is expecting a Mapper[SyncVW] object and it is receiving SyncVW. What
am I doing wrong?
Thanks,
GA
