[Lift] Re: CometActor and JQuery Effects
Mrinal, Do you mean when the page is initially rendered or do you mean on updates? If you mean on updates, see the partialUpdate(js: JsCmd) method on CometActor: http://scala-tools.org/mvnsites/liftweb/lift-webkit/scaladocs/net/liftweb/http/CometActor.html You can send arbitrary JavaScript to the client to do redrawing, effects, etc. Also, keep in mind that you can chain JsCmd together: val j1: JsCmd = ... val j2: JsCmd = ... val j3 = j1 j2 And you can take a List[JsCmd] and turn it into a JsCmd: val js: JsCmd = jsList.foldLeft[JsCmd](Noop)(_ _) Thanks, David On Fri, Oct 10, 2008 at 6:42 AM, Mrinal Wadhwa [EMAIL PROTECTED]wrote: Hi Everyone, Has anyone tried adding a jQuery effect to the content a CometActor puts on a page .. if so then how to do that?

[Lift] Re: SnippetFailure
It means that the dispatch function on whatever Stateful Snippet is being
called isn't matching what you're asking it to provide. For instance, if
your snippet tag looks like
lift:MySnippet.add
Then the dispatchPf in the MySnippet stateful snippet has to have a dispatch
function like:
val dispatch: DispatchIt = {
case add = some function here _
}
See
http://scala-tools.org/mvnsites-snapshots/liftweb/lift-webkit/scaladocs/index.htmlfor
more details.
I also know that David has recently *strongly* recommended not putting
.html on the ends of things.

[Lift] Re: Progress on JPADemo and JTA
You can do either that, or git checkout -b my_new_branch which will both create and switch to the new branch; you'll then need to do git push origin my_new_branch to get it up on central. For when you want to subsequently pull from that branch, you should probably add something like this to your .git/config: [branch my_new_branch] remote = origin merge = refs/heads/my_new_branch There's some git command that will do this for you, but I can't remember it at the moment as I usually just do it by hand.

[Lift] Re: Progress on JPADemo and JTA
OK, if I've done this correctly, there are only a few things that you need to do to get this working in a JEE container: 1. Edit persistence.xml to: 1. Set the proper dialect 2. Remove or set the proper hibernate.transaction.manager_lookup_class property. I think that Hibernate is smart enough to figure this out inside a container, but it was really pissed if I didn't use this in Jetty 2. Set up the matching datasource There are definitely some things I'm not sure about: 1. How to properly bind the JPA module into JNDI. The code in Model.scala assumes that it will be located in java:comp/env/module name, and I think that I have the persistence-ref set up correctly in web.xml, but I'm not 100% positive 2. How Glassfish plays with Hibernate. We had to use the Hibernate annotations in order to get an Enumeration type. I searched and searched but couldn't find anything concrete for TopLink. Please let me know if you run into any difficulties and hopefully we'll get this sorted out.

I should be able to sort out any glassfish/hibernate issues with the demo, as my Lift/JPA/JTA/Hibernate/Glassfish app is running happily and going into production on Tuesday. In general, I haven't run into any issues whatsoever; all you need is the providerorg.hibernate.ejb.HibernatePersistence/provider entry in the declaration of your persistence unit in persistence.xml.

[Lift] Re: SnippetFailure
Thanks, Derek. Actually, I don't use .html or even add (all my html
files are called index.html -- I use directories to sort them). This
error came when I was experimenting to see if that made a difference.
That said, I get the error all the time. I don't have val dispatch... in
my snippets. But that's because I copied the JPADemo over, and your
AuthorOps and BookOps don't have the val dispatch either. But the
JPADemo doesn't get this error.
Also, my edit functions don't work -- the forms are not populated
properly. I thought I had it working a minute ago, and now it isn't again.
I switched the snippets around a bit and dropped the bind (because I
wanted to color code alternate rows and wasn't sure how to do it
otherwise). Here is an example:

Thanks, Derek. Actually, I don't use .html or even add (all my html
files are called index.html -- I use directories to sort them). This
error came when I was experimenting to see if that made a difference.
That said, I get the error all the time. I don't have val dispatch... in
my snippets. But that's because I copied the JPADemo over, and your
AuthorOps and BookOps don't have the val dispatch either. But the
JPADemo doesn't get this error.
Also, my edit functions don't work -- the forms are not populated
properly. I thought I had it working a minute ago, and now it isn't
again.
I switched the snippets around a bit and dropped the bind (because I
wanted to color code alternate rows and wasn't sure how to do it
otherwise). Here is an example:
snippet/Category.scala:
import scala.xml.{NodeSeq,Text}
import net.liftweb.http.{RequestVar,S,SHtml}
import net.liftweb.util.Helpers
import S._
import Helpers._
import Model._
class CategoryOps {
val formatter = new java.text.SimpleDateFormat(dd MMM )
def getRowClass(r: Int) = {
if (r % 2 == 0) even else odd
}
def list: NodeSeq = {
tr valign=top align=left
th class=textName/th
th class=integerLinks/th
th class=blank /th
th class=blank /th
/tr ::
Model.createNamedQuery[Category](findAllCategories).getResultList().toList.zipWithIndex.flatMap(c
= tr valign=top class={getRowClass(c._2)}
td class=text{c._1.name http://1.name}/td
td class=integer{SHtml.link(/links/search/, {() =
WeblinkOps.resultVar(Model.createNamedQuery[Weblink](
findWeblinksByCategory, id - category.id
http://category.id).getResultList().toList)
}, Text(category.weblinks.size().toString))}/td
td class=edit{SHtml.link(editor, () =
categoryVar(category), Text(Edit))}/td
td class=delete /td
/tr)
}
object categoryVar extends RequestVar(new Category())
def category = categoryVar.is
def editor (xhtml : NodeSeq) : NodeSeq = {
def addOrUpdate () = {
if (category.name.length == 0) {
error(emptyCategory, The category's name cannot be blank)
} else {
Model.merge(category)
redirectTo(/admin/categories/)
}
}
val currentId = category.id http://category.id
form method=POST action=
table class=editor border=0 cellpadding=3 cellspacing=0
tr valign=top align=left
thName/th
td{SHtml.text(category.name http://category.name,
category.name http://category.name = _)}/td
/tr
tr valign=top align=left
th{SHtml.hidden({category.id http://category.id =
currentId})} /th
td{SHtml.submit(Save, addOrUpdate)}/td
/tr
/table
/form
}
}
webapp/admin/categories/editor/index.html:
lift:surround with=default at=content
h2Categories/h2
table class=list
lift:CategoryOps.list/
/table
/lift:surround
And in Boot.scala:
Menu(Loc(categories, List(admin, categories, index),
Categories, LocGroup(admin)),
Menu(Loc(categories_add, List(admin, categories, editor,
index), Add a New Category, Hidden))
),
ANY suggestions for how to do any of this better greatly appreciated. Do
I need to add the val dispatch... part? If so, why is this different
from the JPADemo?
Thanks!
Chas.
