[Lift] Re: Removing Scala Actors from Lift
Hi David, Could you give some short step-by-step guide, how to change the most important stuff in case of compilation errors that are caused because of this? Maybe that would safe some time afterwards. I'm thinking about to start my application exclusively with -o to make sure that no updates are applied.good or bad? thanks Folks, Given the continued instability of Scala Actors, I've decided to remove them from Lift. Specifically, I'm migrating CometActors to sit on top of Lift's Actors. But, you'll also be able to use Akka Actors to power Lift's CometActors. Specifically, I'm working with Jonas to make sure that we share a common interface to Actors. I've gotten Lift nearly completely migrated over to Lift's Actors on the dpp_wip_actorize branch. See http://github.com/dpp/liftweb/tree/dpp_wip_actorize There will be some breaking changes to your applications. Specifically: * Box will be moved to a new package, net.liftweb.base (this is where the interface for Actors will live as well) * If you make any assumptions about your CometActors being Scala Actors (e.g., using linking), you will have to rewrite this code * Some methods in Lift that currently take Scala Actors as parameters will take Lift Actors (e.g., ActorPing) There will be a parallel Maven repository with the new Lift Actor stuff in it so you will be able to build you apps against the new code before the official switch-over. Milestone 6 (which should be out next week) will be based on the existing Actor model. After we get feedback from the community about the new Actor stuff, we will switch -SNAPSHOT over to the new Actor stuff. Questions, thoughts, or comments?

[Lift] table does not exist
Lifters, I defined the table that caused the error and I listet the meta object in Schemifier.schemify(...) inside Boot.scala. Are there any other reason, that might cause this error? Besides that, I've the impression, that sometimes, somethings work, and then after some compilations they don't (without changing anything that relats to it)..I'm using Netbeans 6.7 on Ubuntu 8.04are there any known problems, API breaks whatever? thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Lift runtime error
Hey Lifters, I overrode the toString method of a foreign key field, to make decisions, on what to return, nothing special. When I remove the if/else (Order.scala, line 65 ff.) and return directly the result, no error occurs! I append the source as attachment. Further on, I've a similar error to one I already got (and solved with David's help). Initializing a foreign key field, with a value that doesn't exist at compile time. In line 45 ff. in file Order.scala is the solution, on how to do that. But this doesn't work for line 76 (same file). Why? What I do now, just to have the ability to test some things, is to comment out line 76 before I compile first (create all other tables) and then uncomment it and restart the application. Then it works, but if I don't do that, I get the error that table/view TRADESTATUS doesn't exist. thanks alot in advance! Here is the error that is forced through the if/else in line 65 ff. in file Order.scala. --- Exception occured while processing /limitorder/list Message: java.lang.AbstractMethodError: org.tobster.model.LimitOrder.tradeTypeName2()Ljava/lang/String; org.tobster.model.Order$tradeType$.toString(Order.scala:71) net.liftweb.mapper.MappedField$class.asHtml(MappedField.scala:645) net.liftweb.mapper.MappedLong.asHtml(MappedLong.scala:223) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1$$anonfun$doRowItem$1$1.apply(CRUDify.scala:469) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1$$anonfun$doRowItem$1$1.apply(CRUDify.scala:469) scala.List.flatMap(List.scala:1132) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1.doRowItem$1(CRUDify.scala:468) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1$$anonfun$apply$7.apply(CRUDify.scala:471) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1$$anonfun$apply$7.apply(CRUDify.scala:471) net.liftweb.util.BindHelpers$FuncBindParam.calcValue(BindHelpers.scala:218) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1$$anonfun$apply$24.apply(BindHelpers.scala:433) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1$$anonfun$apply$24.apply(BindHelpers.scala:426) net.liftweb.util.ThreadGlobal.doWith(ThreadGlobal.scala:65) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:425) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:424) scala.Seq$class.flatMap(Seq.scala:294) scala.xml.NodeSeq.flatMap(NodeSeq.scala:34) net.liftweb.util.BindHelpers$$anonfun$bind$2.in_bind$1(BindHelpers.scala:424) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:444) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:424) scala.Seq$class.flatMap(Seq.scala:294) scala.xml.NodeSeq.flatMap(NodeSeq.scala:34) net.liftweb.util.BindHelpers$$anonfun$bind$2.in_bind$1(BindHelpers.scala:424) net.liftweb.util.BindHelpers$$anonfun$bind$2.apply(BindHelpers.scala:449) net.liftweb.util.BindHelpers$$anonfun$bind$2.apply(BindHelpers.scala:409) net.liftweb.util.ThreadGlobal.doWith(ThreadGlobal.scala:65) net.liftweb.util.BindHelpers$class.bind(BindHelpers.scala:409) net.liftweb.util.Helpers$.bind(Helpers.scala:29) net.liftweb.util.BindHelpers$class.bind(BindHelpers.scala:380) net.liftweb.util.Helpers$.bind(Helpers.scala:29) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1.apply(CRUDify.scala:471) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doRows$1$1.apply(CRUDify.scala:467) scala.List.flatMap(List.scala:1132) net.liftweb.mapper.CRUDify$$anon$1.doRows$1(CRUDify.scala:466) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doCrudAll$2.apply(CRUDify.scala:486) net.liftweb.mapper.CRUDify$$anon$1$$anonfun$doCrudAll$2.apply(CRUDify.scala:486) net.liftweb.util.BindHelpers$FuncBindParam.calcValue(BindHelpers.scala:218) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1$$anonfun$apply$24.apply(BindHelpers.scala:433) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1$$anonfun$apply$24.apply(BindHelpers.scala:426) net.liftweb.util.ThreadGlobal.doWith(ThreadGlobal.scala:65) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:425) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:424) scala.Seq$class.flatMap(Seq.scala:294) scala.xml.NodeSeq.flatMap(NodeSeq.scala:34) net.liftweb.util.BindHelpers$$anonfun$bind$2.in_bind$1(BindHelpers.scala:424) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:444) net.liftweb.util.BindHelpers$$anonfun$bind$2$$anonfun$in_bind$1$1.apply(BindHelpers.scala:424)

[Lift] Re: table does not exist
I don't think soI'm using Ubuntu:-) I just saw, that I got a little bit confused, because I wrote two mails. And the thing is, that the problem with if/else in override def toString now works fine. But there's still this one lelf. So I still get the table/view doesn't exist error, when I first start after I wiped out the entire database. thanks.

Don't know if this is an accident, but since yesterday I'm getting this error too (and I didn't touched Boot.scala)? I have two webapps, hosted on the same server: http://lsug.org/main/ http://lsug.org/stage/ Problem is, the menu works just fine on the stage site, but not on the main site. Which is odd, as these sites should be identical. I just renamed stage.war to main.war and let tomcat auto-deploy it The site is using tomcat 6 via apache 2 (with mod_jk proxying) The problem also appears if I access tomcat directly (i.e. not via apache) Is this a known issue? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

I tried things like this.lots.is or this.lots.i_is_! but without

[Lift] Re: selectObj again
Hi Dave,
thanks again! But I can't find any documentation about the selectType
method. I looked at the API docs on the website, but in SHtml the
selectType method didn't exist!? Even inside the sources from SHtml on
github selectType wasn't there
Can you tell me how to use and maybe a short code snippet?
thanks and sorry for wasting your time...
Try: SHtml.selectType[TradeType]()

I modified the code a little bit:
object tradeType extends
MappedLongForeignKey(this.asInstanceOf[MapperType], TradeTypeMetaObj){
override def _toForm = Full(SHtml.selectObj[TradeType]
(List(
(TradeTypeMetaObj.findAll(By(TradeTypeMetaObj.name, BUY))(0), kaufen),

verkaufen)),
Full(TradeTypeMetaObj.findAll(By(TradeTypeMetaObj.name, BUY))(0)),

}
But I still get the same compiler error! Seems like I've to use some
other method instead of set()? I discovered the set() method in one of
the tutorials/Lift Book
any ideas?

thanks!
Tobias,
Please see

I think this does what you want it to.
Please let me know if it doesn't.

[Lift] Re: Develop / Production System
Ok, thanks. Well, with the pom.xml file it was a little bit strange. I had to change the Lift version to do the mvn clean install and then change it back. I've no idea why, but it was the only things that helped. Maven stores project dependencies in a repository (by default, its called .m2). When you move a Lift application from one system to another, the repository on the new system may need to be updated, hence your requirement to do a mvn clean install. Don't know what you changed on the pom.xml (if you have any hard coded paths, you might have to change them).

[Lift] using selectObj
Hi Lifters,
I attempted to modify a MappedLongForeignKey field in my class to
display itself as a drop-down menu.
I wanna select objects from another database table, therefore I used
SHtml.selectObj. Here's the code:
object tradeType extends
MappedLongForeignKey(this.asInstanceOf[MapperType], TradeTypeMetaObj){
override def _toForm =
Full(selectObj(List((TradeTypeMetaObj.findAll(By(TradeTypeMetaObj.name,
BUY)), BUY),
(TradeTypeMetaObj.findAll(By(TradeTypeMetaObj.name, SELL)), SELL)),
Full(is.toString),
(f: TradeType) =
set(f.toString)))
}
I have some problems with the three parameters for selectObj. I don't
understand the two examples (one in the Lift book, p. 53, 4.1.10
selectObj, the other one in the getting started tutorial, p. 18, 2.10
Updating the priority and desc fields). In both examples they use
lists of some data, instead of Lists-Of-Tuples, which is the official
way mentioned in the documentation of the selectObj method in the book.
I think the first parameter should be OK, at least the compiler doesn't
complain about it. The second parameter is as far as I understood it,
the entry that should be selected by default. But I don't really know,
what the third one, the function object awaits from me.
As you can see, the list only contains two objects. I wanna display
BUY for the first one and SELL for the second one. Depending on what
the user selects, the corresponding object should be stored in the
tradeType field. There are only two rows/instances in the TradeType
table, one for BUY and one for SELL.
thanks in advance...

[Lift] Re: set currentUser as owner
Hi Dave,
thanks, after doing the mvn clean the error disappeared. But now I
still have a type error:
error: type mismatch;
[WARNING] found : Any
[WARNING] required: Long
[WARNING] override def defaultValue = User.currentUserId openOr 0L
[WARNING]^
[WARNING] one error found
Seems like the openOr doesn't work...,? Because it should than return
the 0L, or? Therefor, I wrote a method:
def checkIfUserAvailable(usr: Any) = usr match{
case l: Long = l
case a: Any = 0L
}
and invoked it like this:
override def defaultValue = checkIfUserAvailable(User.currentUserId)
I can compile this, but when I run it, seems like every item/order I
create has the same UserId, because all users can see all items/orders.
thanks.
This is our old friend, Scala defect 715... closed for 2.8.0:

Please do a mvn clean jetty:run and all should be good.

Hello Lifters,
I wanted to override the defaultValue of my owner field, to always set

(what I kind of understand). During compilation, there's no
currentUser
so this function call has to be delayed somehow, but how?
The definition of the owner field is inside a trait, is this a
additional reason for this error?
thanks!

CrudType is a type parameter, or? Its not the class nor companion object that mixes in CRUDify...? Because I tried that, too.

Hi Dave, First, is this 1.1 version already in the repository, will maven automatically get it? Second, where do I have to override those methods, in the class that extends Mapper or in the companion object? Can you give a short code sample how to override, please. thanks. I've added new CRUDify stuff for 1.1 (Hudson is building right now). There are 4 methods that you can override: def showAllMenuLocParams: List[Loc.LocParam] = Nil def createMenuLocParams: List[Loc.LocParam] = Nil def viewMenuLocParams: List[Loc.LocParam] = Nil def editMenuLocParams: List[Loc.LocParam] = Nil Just put additional LocParams in these lists (e.g., If(), Unless()) and you can set access control.

[Lift] Re: create todo item during boot
Dave,
thanks alot man!
cheers

Dude... it's the magic of dbAddTable in the MetaMapper object:
in object ToDo... add:
override def dbAddTable = Full(populate _)
private def populate {
ToDo.create.().save
}
When Schemifier adds a table, it will invoke the function specified by
dbAddTable and that's a perfect place to add the default ToDo item.

[Lift] newbie question: using ajaxText() to get integer from form
Hi There,
From the ToDo tutorial I got this code:
private def desc(td: ToDo, reDraw: () = JsCmd) =
swappable(span{td.desc}/span,
span{ajaxText(td.desc,
v = {td.desc(v).save; reDraw()})}
/span)
What if I've a numeric field, e.g. td.num and I want to view/edit it?
I got to the point that I modified the code to look like this:
span{ajaxText(td.num.toString,
v = {td.desc(v).save; reDraw()})}
/span)
But I still get another compile error, that tells me, that it awaits
String instead of Int.
What do I've to change here? I tried some things with toString() too,
but all didn't worked.
v = {td.num(v).save; reDraw()})}
thanks
Tobias

[Lift] Re: Tutorial No Schemify in Boot.scala
Hi Eric, By the way, is there any documentation about the different maven2 lift-archetype-something options? I wanted to setup a lift project that has the login stuff already included, but since I didn't know why, I used the ToDo project and modified it. Are there other solutions? thanks Tobias Jeff, I am assuming that you are referring to Starting with Lift by Chen-Becker, Danciu, Pollak, and Weir. Chapter 1 introduces a simple application that is created from lift-archetype-blank and has no support for databases. In Chapter 2, that application is thrown away and a new application is created with lift-archetype-basic which does have support for databases. I think you are still trying to use a lift-archetype-blank application when following along with examples that require a lift-archetype-basic application. Hope this helps.

I am following GetStartedGuide and working on the todo app. However in 2.4, I cannot find the Schemifier statement in the Boot.scala file. Did I miss anything? I also didn't find the part on how to connect Lift with a backend database. Thanks, Jeff --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Netbeans
To get syntax highlighting and all that stuff in Netbeans go to: http://wiki.netbeans.org/Scala#section-Scala-1.GetStartedWithNetBeans6.5 Good evening, I´ve been looking at Lift, did a bit of command line but I want to use it in Netbeans, unfortunately the only google results about Lift, Scala, and Netbeans are gone (404) even the Scala netbeans Wiki 404´s. Is there a tut I can look at? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.
