[Lift] Re: Menu generated from database?
Hi Ross,
Thanks for the code - however it didn't compile on my machine, why is
that?
Also I cannot get it to show a menu, can you take a brief look at my
code, whats the problem? I notice supplimentalKidMenuItems gets called
every time the page is rendered so thats a positive, but no menu items
added to the page. Obviously I am a beginner, don't know why I had to
change Unit to NullLocParams to get it to compile.
I am on scala.version2.7.5/scala.version
Lift version version1.1-M6/version
I changed code to:
case class DynMenuLoc (
override val name: String,
override val link: Link[NullLocParams],
override val text: LinkText[NullLocParams],
_params: LocParam* ) extends Loc[NullLocParams] {
override val params = _params.toList
// had to comment this out: override val defaultValue = Full(())
// not sure what to set this to
override val defaultParams = Empty
override def supplimentalKidMenuItems:List
[net.liftweb.sitemap.MenuItem] = {
Log.info(kid menu function called)
var result:ListBuffer[net.liftweb.sitemap.MenuItem] = new
ListBuffer[net.liftweb.sitemap.MenuItem]
result + (new MenuItem(Text(A), Text(B), Nil, false, false,
Nil))
result.toList ::: super.supplimentalKidMenuItems
}
}
def menu: List[Menu] =
{
Menu(Loc(home, List(index), Home)) ::
Menu(DynMenuLoc(Dynamic Menu, Link(List(dynamic), true, /
dynamic), Dynamic Menu)) :: Nil
}
Thanks, Philip

Also I guess there is another problem with this approach, it does not
render the entire menu, only one of 2nd level menu items. The 1st
level menu items are Menu. Am I right in saying this?

[Lift] Re: Menu generated from database?
Got my code working so it generates a menu.
Looked at WikiLoc in the Wiki Liftweb example, it has:
def defaultParams = Full(WikiLoc(HomePage, false))
So I guessed that it needs to have something with a Full
Changed it to:
override val defaultParams = Full(NullLocParams)
So now my code is
case class DynMenuLoc (
override val name: String,
override val link: Link[NullLocParams],
override val text: LinkText[NullLocParams],
_params: LocParam* ) extends Loc[NullLocParams] {
override val params = _params.toList
// had to comment this out: override val defaultValue = Full(())
// not sure what to set this to
override val defaultParams = Full(NullLocParams)
override def supplimentalKidMenuItems:List
[net.liftweb.sitemap.MenuItem] = {
Log.info(kid menu function called)
var result:ListBuffer[net.liftweb.sitemap.MenuItem] = new
ListBuffer[net.liftweb.sitemap.MenuItem]
result + (new MenuItem(Text(A), Text(B), Nil, false,
false, Nil))
result + (new MenuItem(Text(C), Text(D), Nil, false,
false, Nil))
result.toList ::: super.supplimentalKidMenuItems
}
}
Thats great, but still there is a problem of the top level menu.

[Lift] Devoxx 2009
Folks, I got back from Devoxx late last night and thought I would just post some thoughts and experiences from the event. Firstly, there was an awesome interest in Scala and Lift - my talk was really busy (~550 people) and the general Scala Enthusiast BOF right afterwards was packed. Myself, Bill Venners, Viktor Klang and Frank Sommers pretty much represented a cross-section of Scala projects at the BOF and throughout the whole week we were pretty much swamped with Scala questions and interest. Lift was getting a lot of attention and was even used by Oracle in the Devoxx keynote!!! Another event of note was when myself, viktor and john were sat in the hotel reception hacking on Scala and showing it so some interested people at around 10pm, the JavaPosse turned up and were like wow, we appear to have stumbled upon the Scala geeks - they then proceeded to join the hackfest which was über cool. All in all, a very very successful week and I think the above mentioned group did an amazing job of raising the profile of Scala even further; moreover, some of the Lift discussions were brilliant - appeared to be a lot of people wanting to convert from Spring bean hell ;-) We as a team should be made up with the awesome framework that has been created here -- the next 12 months I believe will be somewhat of a Scala / Lift golden age where we have the opportunity to really make our mark on the industry.

[Lift] InputStream to String
I have seen this problem around and it seems basic but I haven't found
a solution. I need to turn an InputStream into a String. There seems
to be a bug in the Source class that fails for large files so I don't
want to use that (though it is an elegant approach).
The following doesn't work because reader.readLine returns Unit and
not null, as in Java.
val reader = new BufferedReader(new InputStreamReader(is))
var responseBody =
var line = reader.readLine()
while(line != null){
responseBody += line
line = reader.readLine()
}
return responseBody
What to do?

not null, as in Java.
val reader = new BufferedReader(new InputStreamReader(is))

var line = reader.readLine()

[Lift] Re: Call it Lift 2.0
Hi, Heiko, can you find the stated version number policies of 3 or 4 other well regarded open source projects? That will allow us to synthesize the best of what others have done into a coherent policy for Lift. Take a look at the recommended OSGi version policy: http://www.aqute.biz/Code/XBnd Then take a look at Eclipse (pretty well known, eh?): http://wiki.eclipse.org/index.php/Version_Numbering Both use a major increment (1.x - 2) to show breaking changes in API, a minor increment (1.1.x - 1.2) to show non-breaking changes in API and a micro increment to show internal (no class name changes, no method signature changes, ...) changes (e.g. bug fixes in the implementation). -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] Re: scala eclipse plugin with lift

[Lift] Basic view question
Hi,
I just created a simple project with the maven archetype and tried to add a
view as explained in the The Definitive Guide to Lift.
package org.opicasso.two.view
import net.liftweb.http.LiftView
import scala.xml.NodeSeq
class SomeView extends LiftView {
override def dispatch = {
case show = doShow _
}
def doShow () : NodeSeq = {
lift:surround with=default at=content
h1hello/h1
/lift:surround
}
}
The Boot class was not changed:
package bootstrap.liftweb
import _root_.net.liftweb.util._
import _root_.net.liftweb.http._
import _root_.net.liftweb.sitemap._
import _root_.net.liftweb.sitemap.Loc._
import Helpers._
/**
* A class that's instantiated early and run. It allows the application
* to modify lift's environment
*/
class Boot {
def boot {
// where to search snippet
LiftRules.addToPackages(org.opicasso.two)
// Build SiteMap
val entries = Menu(Loc(Home, List(index), Home)) :: Nil
LiftRules.setSiteMap(SiteMap(entries:_*))
}
}
However when trying
http://localhost:8080/SomeView/show
I get
The Requested URL /SomeView/show was not found on this server
Is there something else that needs to be done? Is the url correct?

[Lift] Issue 201 - checkbox not returning all checked
yejun on github opened up an issue: def checkbox[T](possible : Seq[T], actual : Seq[T], func : (Seq[T]) = Any, attrs : (String, String)*) Func will only return first element in possible when it is checked or List(). It is easily reproducible. Based on the type of func, I agree it looks like it should give all checked boxes, not just either the first checked box or an empty list. If it's supposed to be for a single checkbox only, then I think the type should be changed to Box[T] = Any, or at the very least a doc comment indicating that it only supports a single check box. This behavior was introduced withhttp://github.com/dpp/liftweb/commit/ 8b2a92a58ded608a0d3a7b6ead29cd2af6302c5e. Since there is no doc comment on the function I wanted to check what is the intended behavior before making and posting a patch to either do multiple checkbox or make the doc comment / type more clear and add another function to do the multi behavior.

Re: [Lift] Re: Menu generated from database?
Yeah, Full(()) makes sense for 1.1-SNAPSHOT which is what my code was using,
and Full(NullLocParams) makes sense for M7 and earlier. I apologize; I should
have asked what version you were developing against.
I think that you are correct with regard to the top level menu having to be
static -- looking at it it seems like only child menu items can be dynamic.
Maybe you can have one top level Menu and then use a custom Menu snippet that
skips the top level? Someone with more experience doing deep SiteMap stuff
hopefully can chime in.

Thats great, but still there is a problem of the top level menu.

Hi David,
Since I am programming a CMS for my client, I need my lift menu to
come from the database.
LiftRules.setSiteMap(SiteMap(MenuInfo.menu :_*))
def menu: List[Menu] =
{
Log.info(Menu called)
...
It seems my menu function only gets called once, on subsquent calls I
do not get any log message.
Maybe I have to subclass SiteMap?
Can you point me in the right direction?
Thanks, Philip

Hi,
How can I get a Liftweb menu to be generated from database content?
Alternatively, can the menu come from a XML datasource? could I load/
serialize from that?
Could it change dynamically at any time?
Thanks, Philip

[Lift] Change to support dynamic top level menu items
In the recent thread, a couple people asked for the ability to create dynamic
menu items per request from the database. David suggested
Loc.supplimentalKidMenuItems which works fine for dynamic children of a static
menu, but doesn't support the ability to make the top level menu dynamic.
Menu has a method called makeMenuItem which gives a Box of MenuItem. What
about a new method makeMenuItems that gives a possible plurality of MenuItems
whose default implementation deferred to the existing makeMenuItem in the case
where it's not overridden? I made this change to my local copy of lift and it
seems to work alright.
Example Menu:
case class DynMenu() extends Menu(Loc(dynmenu, Link(List(dynmenu), true,
/dynmenu), Dynamic Menu)) {
override def makeMenuItems(path: List[Loc[_]]): Iterable[MenuItem] =
DynMenuItem.findAll.map(dmi = {
MenuItem(Text(dmi.label.is), Text(dmi.link.is), Nil, false, false,
Nil)
})
}
That is, a Menu can generate 0 or more MenuItems when the menu is being
generated. The disadvantage I see is similar to the one with
supplimentalKidMenuItems -- that is, you have to manually compute the
attributes of MenuItem such as current. However, it does give you the full
power to make whatever kind of menu items you want.
I looked briefly at seeing if it would be feasible to use a function Box[Req]
= SiteMap on LiftRules, but I think the RewritePF auto detection thing in
LiftRules.setSiteMap prevents this from being the right thing.
The change to lift-webkit:

[Lift] NPE in S.?! if used outside a request
I'm poking around the LiftTicket codebase, and currently it suffers from an NPE
on Boot:

This is apparently due to S._resBundle being null because S.init has not yet
been entered, so S._resBundle.doWith(Nil) is not in the enclosing scope, and so:
private def ?!(str: String, resBundle: List[ResourceBundle]): String =

S.resourceBundles, which is defined thus:
def resourceBundles: List[ResourceBundle] = {
_resBundle.value match {
case Nil = {

}
case bundles = bundles
}
}
I don't think the resource bundles can be reasonably loaded outside a request
since no locale can be computed -- the call site should lazily compute the menu
text at request time using LinkText rather than eagerly using S.?, but the
error case is not helpful. What I propose is changing S.resourceBundles like
this:
def resourceBundles: List[ResourceBundle] = {
_resBundle.box match {
case Full(Nil) = {

case Full(bundles) = bundles

Re: [Lift] NPE in S.?! if used outside a request
It's being called to provide the link text for menus during sitemap creation at
boot time, as well as during class initialization time to make some vals that
contain error text. I believe initializing these at Boot time to be incorrect
since the correct locale cannot be known until a request is made (unless you
force one locale for the entire site, I guess), but the NPE seems uglier than
providing an error log explaining the problem.

Re: [Lift] NPE in S.?! if used outside a request
I agree that getting an NPE is less than desirable!
I'm not sure things are wrong per-say; the defualt locale calculator
has an app wide setting and there is nothing to say that that a user
must implement their locale calculator in a particular way... This is
one of the great things about lift ;-)
So the issue here seems to be the lazy / eager evaluation of bald
rather than localization out of request context? I'm all for getting
rid of these NPE scenarios though :-)

Re: [Lift] NPE in S.?! if used outside a request
Hmm, you raise an interesting point. So I guess the situation is more
variegated:
1) If you have a locale calculator that works per-request and does not have an
app default, then it is definitely incorrect to call S.? out of a request
context,
2) but if you have one that works app-wide then it should work -- but doesn't,
unless you call S.init or one of those by yourself,
3) so my proposed error is not good.
It would be nice to catch uses of S.? outside of a request context when your
intended behavior is that you only have per-request locales, so I guess if that
is the desire then one should make their locale calculator log the error text,
and the change to lift should be something more like:
def resourceBundles: List[ResourceBundle] = {
-_resBundle.value match {
- case Nil = {
+_resBundle.box match {
+ case Full(bundles) if !bundles.isEmpty = bundles
+ case _ = {
_resBundle.set(LiftRules.resourceNames.flatMap(name = tryo(
List(ResourceBundle.getBundle(name, locale))
).openOr(
NamedPF.applyBox((name, locale),
LiftRules.resourceBundleFactories.toList).map(List(_)) openOr Nil
)))
_resBundle.value
}
- case bundles = bundles
}
}
That is, if the _resBundle ThreadGlobal has not been initialized yet, or it's
been initialized with the empty list, then do resource bundle loading. If it
has been initialized with a non-empty list then use that.
I don't think this should interact badly with S.init, since S.init uses
_resBundle.doWith(Nil) ... which will both overwrite any loaded app-level
bundles with the empty list, but also restore them upon completion of the S
scope.

This is apparently due to S._resBundle being null because S.init has
not yet been entered, so S._resBundle.doWith(Nil) is not in the
enclosing scope, and so:
private def ?!(str: String, resBundle: List[ResourceBundle]):
String = resBundle.flatMap(r = tryo(r.getObject(str) match {
Blows up with NPE. resBundle is passed in from S.? by calling
S.resourceBundles, which is defined thus:
def resourceBundles: List[ResourceBundle] = {
_resBundle.value match {
case Nil = {
// loads the resource bundles here
}
case bundles = bundles
}
}
I don't think the resource bundles can be reasonably loaded outside
a request since no locale can be computed -- the call site should
lazily compute the menu text at request time using LinkText rather
than eagerly using S.?, but the error case is not helpful. What I
propose is changing S.resourceBundles like this:
def resourceBundles: List[ResourceBundle] = {
_resBundle.box match {
case Full(Nil) = {
// same code
}
case Full(bundles) = bundles
case _ = {
Log.error(Resource bundles cannot be loaded outside of a
request scope since the current locale cannot be computed. Did you
use S.? during Boot time?)
Nil
}
}
}
Re: [Lift] JPA and eager fetch
OK - just a quick follow up.
I got a chance this afternoon to test the simple demo app that
Jean-Luc suggested. I changed the mapping on books to be
fetch=EAGER. and put a debug statement on the list method in
authorOps. Of course it works just fine :-) - so the problem lies
somewhere else in my code.
I'll keep digging.

Jim and Jean-Luc - thanks so much for your offer of assistance.
It might take me a while to put together a buildable sample. I'm just
learning lift and scala right now. This is not a critical problem for
me, and I can work around it. When I have something I will post a
follow up.

Your mapping looks like normal.
If you provide a buildable project, either tgz or link to github.com, I may
be able to reproduce your problem and help you identify the issue.

Newbie Lift / JPA alert!
I am sure I am doing something dumb here, but I can't quite figure it
out. I have a JPA project (modelled after the lift JPA demo app).
I have an object with a one-to-many association, and I want to eager
fetch the collection. It is declared like :
�...@onetomany(){ val targetEntity = classOf[OpenIdUser], val cascade =
Array(CascadeType.ALL), val fetch=FetchType.EAGER}
var openIds : _root_.java.util.Set[OpenIdUser] = new
_root_.java.util.HashSet[OpenIdUser]()
In my spa persistence unit, eager fetching works fine from the unit
test. The unit test uses plain old emf factory instances.
However, from my web application (run with jetty:run) and using
Model.createNamedQuery, or Model.find, only the parent object is
fetched. The collection is not.
I gather this has something to do with the way that Model works? Or
are my annotations being ignored when they are packed in a .jar file?
Clues would be appreciated.
Thanks
Warren

[Lift] H2 Database?
Hi all, I'm planning for a simple project that involves a small web site and database. I plan to use Lift for the web part so that I can learn it. For database, I'm interested in H2 database for its speed and flexibility. I've seen H2 database mentioned a few times on the list. I wonder if those who have used it can tell me if it's a good idea to start a lift project with H2 database, and if there are anything to pay attention to when used with Lift? Do you use it in a standalone mode or embedded mode? Thanks. -- You received this message because you are subscribed to the Google Groups Lift group.

Re: [Lift] Issue 201 - checkbox not returning all checked
Looks like I was over-eager with the HPP stuff. Yeah, checkbox should return the entire list of things checked.
