Re: [DISCUSS] JavaScript, Degradation, Page Load, Script Placement
Hello, Further, on a page that loads slowly (one that has a large number of external scripts, is accessed via a slow-bandwidth pipe, or has a very complex layout), this means that JavaScript event handlers are not wired up until all JavaScript has been downloaded and parsed. The end result it that you can outrace Tapestry, click a link that should update a zone and get incorrect behavior or even a runtime exception. I actually see this when using Formo's time-tracking application from home through a slow pipe, exacerbated by HTTPS, where I get the error that Block is not a valid response type. What should have been an Ajax request was processed instead as a traditional page render request, because the JavaScript was not ready. For this problem, doesn't the solution is server side ? I mean, if the (non-XHR) request return a Block, it's an error in T5, and all in all, there is no gracefull degradation. The server code should always distinguish between XHR events and normal requests, and return accordingly. Or perhaps it's a case of leaky abstraction : event handlers for normal requests and for XHR one's might be actually different beasts (onXhrAction / onAction ). I remember that there was several threads on that subject, especially this one : http://markmail.org/thread/ho3nla6eciyupcah Francois - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Switch from Prototype to jQuery?
Whether or not one likes jQuery or not isn't the point. Tapestry is built with prototype, and it works. That's the point. Were it built with jQuery, I would have raised the same question if the suggestion of switching to prototype had been brought up. It's not my preference that's behind my resistance, it's the simple pragmatism of if it ain't broke don't fix it. On the other hand, the prospect of a pluggable JS framework is interesting and I'm all for that. That is a feature; an improvement. A wholesale switch from prototype to jQuery just doesn't seem like time well-spent. Can't agree more :) - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Scala - Tapestry 5 : inject services, access properties
I updated my blog about T5 with a Scala back-end. This article shows a first service and how to access bean properties. The article is here: http://fanf42.blogspot.com/2009/01/t5-scala-first-injection-and-property.html And the code is available on Github: http://github.com/fanf/scala-t5-blog/tree/article2_20090111 Enjoy, Francois Armand - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Tapestry 5 + Scala : an hello world example
Hello, I'm building a toy application to see how Scala and Tapestry 5 get together. The first step was to translate the quickstart application into Scala (that was a little first step ;). Scala is a functional/object oriented language that runs on the JVM, and which I appreciate a lot more than Java (more expressive, and statically typed, and yes it was obvious that I don't spend my spare time on things that I dislike :). Info about the language may be found here: http://scala-lang.org I will try to extend the application in the next weeks, and see if I encounter major problems or if everything goes for the best. The source code is available on github: http://github.com/fanf/scala-t5-blog/ You will find more information about how to get the code on my blog: http://fanf42.blogspot.com/ and more precisely: http://fanf42.blogspot.com/2009/01/tapestry-5-with-scala-get-code.html Enjoy !

[T5] Tapestry 5 and OSGi
Hello dear list, A co-worker and I need to integrate T5 with OSGi. For now, we are just on the proof of concept part of the project, and I am actually discovering OSGi. I know that several users did already have integrated T5 and OSGi (found http://markmail.org/search/?q=list%3Aorg.apache.tapestry.users+osgi ), and I would be really graceful about any help on that topic. I will particularly appreciate any information about what was achieved, what was the problems encountered, what was the best practices, etc. I hope to be able to write an hwoto on that subject to let other users who may want to try the OSGi experience the more information on the subject.

Re: T5 5.0.16 @Paramerter and @Property on same field
Hi, [...] The odd thing is that now we are getting an exception. Does @Parameter transform a field into a final field now? I don't see any reference to same in the release notes. [..] I think that a @parameter field is read-only from the component point of view, it's read/write only for the parent component (page and/or the component which use it). It's not clearly explained in http://tapestry.apache.org/tapestry5/guide/parameters.html, but it's the way I understand it... Perhaps other people have more insight on that point ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tapestry users declined for the first time in 3 years, says this researh site ...
[...] We've stated on several occasions and in public that we don't like trolls either (here for instance: http://chillenious.wordpress.com/2007/02/06/is-there-a-wicket-tapestry-feud/). The whole my group vs your group is so incredibly childish. And the trolls are probably laughing their asses off right now. Ignoring them works better. Eelco (from the Wicket 'community') Jonathan, Eelco, I'm going to speak only for me but I really appreciate what you did here. It's really cool that you came and explained clearly what is going on with this Rob. He brought a quite unsound mood here, and I hope that your mails will clearly, definitely stop these troll, or at least that now, we will actually stop answering him. Thanks, and long life to Wicket :) Francois Armand - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5 Desired complex community components
Hello ! I was wondering what kind of components people are looking for that are not yet available as an open source example. [...] What else is out there (either on the web or in a rich client) that you'd rather not reinvent? I think that a tree component would be great. The component could be used to traverse tree structure as, for exemple, directory tree or menu.

[T5][Info] Scala Programming langage works with T5
Hello guys,
I just began to play with Scala ( http://www.scala-lang.org/index.html ),
a functional, full-OO programming language that run on top of the JVM.
And you know what ? I attempt to build a page in Scala for Tapestry 5, and
it works ! Scala allows to import Java class and use annotation, so I
think that we could use Tapestry 5 full power with Scala.
So, for whose of you who are tired of Java as a language and want to
explore new paradigm, but think that OCaml, Haskell or Erlang are just a
little to cryptic, go for Scala on Tapestry 5 :)
Here an example of the page built (I'm really new to Scala, so the code
may be totally not idiomatic), but it's just to show that it works :
