and what would a wicket standard give you?
Except that those idiotic managers then say its standardized.. now you can
use it why is that is a standard for ever? dont think so everything dies.
But would it run on more platforms?
Would we have multiply implementations? Because thats most of the time a
JCP/JSR does, it doesnt have an implementation, what wicket is, but a
description/interfaces what an implementation should do..

  I totally agree that the JSR process is horrid. However, Wicket could
 really use some more corporate credibility (which a JSR would provide).
  The problem, I guess is that there are simply no corporate interests
 behind Wicket that would push the agenda. What wicket need is some
 evangelism, but I guess all the core people have real jobs. What we need is
 less talks titled why wicket is cool and more cut your development costs
 in two with Wicket. From experience, I am totally convinced that you can
 save 50% off your development costs if you switch to wicket (from just about
 any other framework), however, I've yet to find a contracting job here in
 Zürich where wicket is asked for (it's JSF, or even Struts).

   We're happy to announce a lot of Wicket involvement at the upcoming
   ApacheCon in Amsterdam (23-27 March 2009)
  
   First of all we have 2 training sessions available:
- Introduction to Wicket by Martijn Dashorst on Mon 23 March
   (http://tinyurl.com/aceu09wicket1)
- Behavior-Driving Your Apache Wicket Application by Timo
   Rantalaiho on Tue 24 March (http://tinyurl.com/aceu09wicket2)
  
   Both courses are hosted by core members. Martijn has co-authored
   Wicket in Action and Timo has been involved with WicketTester and
   JDave. There is no better team to get you and your team up to speed
   with the finest Java web framework available and start cranking out
   fully tested applications.
  
   Martijn will also present Wicket in Action during the normal
   conference days. A quick introduction to Wicket's core features in
 just one hour.
   But attending the conference will give you much more:
   over 60 sessions covering your favorite Apache projects.
  
   Amsterdam is great, but Wicket meetups in Amsterdam are even better!
   We're attempting to schedule a Wicket meetup during the conference
   at the conference floor. Details will follow soon.
  
   Read more about ApacheCon EU 2009 here:

Re: Correct way to deal with serialization and casting

2009-02-13 Thread pieter claassen

Ok, feedback on my own problem. It seems that if you create a private
variable and assign an IModel to it, then access it from within the
onClick() method in a listview, that it doesn't always work. You have to
explicitly add the model to the Link constructor for this to work.

It seems that the approach below doesn't always work in wicket.

Thanks for the feedback so far.

Re: Wicket at ApacheCon EU'09 in Amsterdam

2009-02-13 Thread Christopher Armstrong


Hi all

I'm new to this list (and Wicket), and was interested in this  
discussion.


On 12/02/2009, at 11:32 PM, Hoover, William wrote:


Just out of curiosity... Are there any plans to push a JSR that Wicket

It might be interesting to examine this idea in the context of OSGi.  
OSGi is a standard for componentisation and packaging and component  
lifecycle management that has it roots in embedded devices, and  
incorporates a whole range of further standards related to this type  
of platform. It grew out of efforts that were mostly independent of  
Sun, and has continued to evolve as a standard in a separate  
organisation to the JSR process.


It now has a JSR (277), but the OSGi specifications evolve separately  
of this original JSR. It has multiple implementations (Felix, Equinox,  
Knopflerfish, etc). Its flexibility in its design (extender bundles,  
manifest extensions, whiteboard model, etc assist this) has led to  
many addons that build upon it such as Spring DM, iPOJO, etc. In the  
next version of the specification many of these community ideas will  
be incorporated back into the main specifications. The Core OSGi  
specification doesn't add much to the language, but its Compedium  
specifications, which build upon the Core spec, provide everything  
from configuration management, device resolution, to user  
administration and logging.


Sun were looking at using it in Java 7 in order to modularise the JVM,  
a similar goal to the Apache Harmony project IIRC. They have since  
dropped this goal and have revived JSR 294 for modularisation. OSGi  
continues to move along alone and gain its own popularity without the  
JSR/JCP process. Sun's attitude seems to be to just ignore OSGi (a  
form of NIH syndrome?).


IMHO what this means for Wicket is: unless it provides a small base  
for lots of extra functionality to be built upon, its just going to  
get mired in the politics of the JSR/JCP process and not really  
achieve anything. It will probably end up being shunned as a  
competitor to JSF and left unresolved.


It may be better for Wicket to look at managing its own APIs so there  
is less breakage between versions (note: I've only begun using Wicket  
recently so I'm not trying to suggest this is the case) and that  
versions are clearly delineated in terms of API compatibility between  
them. It could try and elevate the Wicket extensions to be more  
tightly managed within the Wicket project, and seek from time to time  
to incorporate these back in into the Wicket mainline. In this way,  
Wicket becomes standardised but still maintains the freedom to  
innovate more quickly. Wicket seems to be tightly modularised enough  
(or able to modularised) that using Wicket as a base to grow new and  
interesting functionality whilst maintaining a stable core seems  
feasible.


Cheers
Chris

Re: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

2009-02-13 Thread Martin Voigt

Hi,

i think the manual page of sl4j http://www.slf4j.org/manual.html makes
it very clear, just read the small red part.

As for the wicket homepage, this would fit into the wiki if it's not
already there. But since wicket uses maven and most projects that use
wicket also use it, missing jars are an issue of the past (well, it's
missing dependencies now ;) ).

If you can I'd suggest you use maven as your build and dependency
management tool for your project.

 want to use commons-logging or JDK14 logging or something else, please see
 the SLF4J site for more information.

  Imagine the example http://wicketstuff.org/wicket13/ajax/tabbed-panel.1
  If I click on first tab, instead of showing This is tab-panel 1 it would
  show, or at least I would like to, show another tabbed panel with tabs
 and
  those would have panels.
 
  Is it possible?  how?

I am trying to figure out what tag is beeing expected...

}

This is the implementation of CadastroTab

Re: Adding/Replacing links in Panels

2009-02-13 Thread Michael Sparer


personally I'm no fan of conditional adding components with the same id.
e.g.
if (user.isSignedIn() {
add(new SignedInPanel(foo));
else {
add(new SignedOutPanel(foo));
}

I rather add all panels and make them invisible or visible

add(new SignedInPanel(foo).setVisible(user.isSignedIn()); // or override
isvisible if that may change ...
add(new SignedOutPanel(bar).setVisible(!user.isSignedIn()); 

this way you always know which panels are added to the page and what they
are ...

Re: Wicket at ApacheCon EU'09 in Amsterdam

2009-02-13 Thread francisco treacy

totally against pushing wicket as a standard / jsr.

it has already been stated by some of you, but i'd like to highlight
the fact that bureaucracy goes against flexibility.

instead of having wicket to change to please management, why don't we
push to have more managers that think out-of-the-box and choose wicket
for its actual strengths rather than because it wears a jcp badge?

Re: Adding/Replacing links in Panels

Yes, but in my case, I dont need separate panels (the only variable being the
link, and everything else remains constant). I might then as well include
the markup in each of the files.

What's your take on handling markup in properties, html, wicket

Hi,

Just wondering how this should be handled without DRY.

In many scenarios we have multiple languages that should have the same
markup but different text. This could be handled by using variation and put
every language in an own html file like myWicketPage_style_en.html.

However, this is not the optimal way and I don't think variation is made for
this either. It would be very annoing having 14 different html files if we
have 14 different languages that we should support.

Sometimes the languages should look different ( not the same look. Different
positioning of elements ) and here we could use variation. As far as I'm
concerned this is not the right way of handling look and feel. Different css
should be used instead and then place position, coloring of the markup in a
css. The html file should be the same and the css should handle the layout.
Take a look at http://www.csszengarden.com/ http://www.csszengarden.com/

Every time I'm dealing with multiple languages the user wants bold, italic,
color in the text. Many times a list will appear just containing text. (
Nothing to do with extracting data from database and let wicket handle it )
This could be added in a properties file but then we would have bold tags,
italic and style tags in the properties file. If something should change we
need to go thru 14 properties files to change the markup in the properties.

Let's say we have the following text in many different languages. Some
markup is changed so you know what I mean.

boldWelcome to our company/boldbrbrHere is some long
text.ullisome [BOLD]text[/BOLD]/liliother text/li/ul

Now imaging this text to be very long.

Now, my question is this. How do you handle tagged markup for different
languages without repeating markup tags.

* Variation and the text in the html file.
* different properties file with markup in it
* Other technique?

RE: Wicket at ApacheCon EU'09 in Amsterdam

I hear the arguments and I completely agree with the notion that innovation 
usually happens elsewhere and a JSR/JCP would slow that process down. I just 
want to objectively view the other side of the spectrum :o)

From a developers point-of-view standardization can often be a thorn in our 
side, but for management it can offer a 
vendor-independent/implementation-independent solution. Maintaining/upgrading 
infrastructure is difficult, expensive and time consuming. From the 
point-of-view of management a standard can often minimize the risk of vender 
lock-in.

Another thing to consider is that a broader multi-community involvement could 
also bread innovation. There may be other innovators from other communities 
that may have valuable input that could improve Wicket in ways that may have 
not been previously considered. IMHO, the biggest argument for JSR/JCP is that 
there is often a broader involvement in the process. Hibernate, for instance, 
was in a similar position a few years back when they introduced a new 
persistence concept. They have since become heavily involved in the JPA 
specification process. When I first worked with Hibernate, like many, I was 
very impressed (similar to the first time I worked with Wicket :o), but looking 
back at how Hiberante initially did things to how they do them now there are 
some huge improvements due to the JPA specification.

My hope is that the Wicket community can be as open-minded to this notion as 
they are to the open source code they represent :o)

Setting TreeState in new page

2009-02-13 Thread Seven Corners


I have a LinkTree where each node contains links to pages, and each of these
pages derives from the same base class, so they all contain that LinkTree. 
When a user drills down into the tree on one page and then clicks a link for
another page, I'd like the new page we go to to open the tree to its state
in the last page.

I can save the TreeState to the session and retrieve it in the new page, but
that's not the problem.

Right now, in the new page, the new tree displays collapsed.  When you leave
your constructor, only the topmost tree node has been constructed.  The node
I want to drill down to isn't created until you click on a junction link.

I could have designed this where the application has only one URL and only
the right-hand panel changes as you click through AjaxLinks -- and I had
that working with a minimum of trouble, but then I learned I have a
requirement that each view of the system -- i.e., where the right-hand
panel shows different content -- must correspond to a bookmarkable link. 
This requirement also eliminates the option of using frames wherein the
navigation tree stays the same and the part that's supposed to change, the
right-hand panel, is the target of the links.

So how do I open up my tree when I get to the new page?

Thanks for your help.

I am not sure what you would like to standardize. Given your JPA 
example, I would guess that you want to push a JSR for a web framework 
or something. But there is already something like that: JSF. Just let 
Wicket be Wicket and instead of changing Wicket (and it's community) in 
the wrong way, let's try to change the views of corporate managers in 
the right way. As Thomas said earlier What we need is less talks titled 
'why wicket is cool' and more 'cut your development costs in two with 
Wicket' .


And I do not think that the lack of support for pushing a JSR has 
anything to do with a lack of open-mindedness...

2009-02-13 Thread francisco treacy

this has nothing to do with being open-minded.

i'm pretty sure that most non-trivial projects out there using jpa
with hibernate implementation can go through a big pain if they ever
decide to change jpa vendor.
 now that you talk about jpa, this is an example of how backward a
spec can be: jpa 2.0 draft is only now addressing criteria, when we
should be including statically-typed queries and so on (ala linq /
quaere / jaqu).

granted the process might bring some benefit to wicket, but there are
way too many disadvantages, imo. and i don't really see how wicket
could become a sort of standard that gets different implementations.

anyway, i think we've got waaay out of topic =)

2009-02-13 Thread Jan Kriesten


Hi,

I can't really think of any specification which would make sense to build -
there is just no need for that IMHO.

If managers need something like that - there's JSF. And knowledge is growing
that JSF isn't the ultimate answer. There are other open source projects
embraced by managers as well without being an official standard - else why would
there be so many Struts applications out there?!

Also, Wicket does support a standard, which makes it quite valuable: Portlets!
Does Tapestry do that?

RE: Wicket at ApacheCon EU'09 in Amsterdam

I agree that we need to change the views of corporate managers in the
right way by illustrating the cost savings achieved though a reduction
in development time. At the same time, I don't believe that this will
change the Wicket community in the wrong way (which is a highly
subjective statement). I'm only presenting the alternative viewpoint. It
is possible that a standard could potentially inhibit progression due to
contrasting viewpoints within the community, but it is also equally
possible that it could lead to a value-added aspect by introducing a
broader input base to the Wicket community that could speed progression
(Hibernate/JPA is an example of this). There is always a possibility
that progress can be slowed as the number of members increase because
there are more viewpoints to be examined/debated. I think that there is
a higher probability that the community will grow if such a standard
were to be adopted.

Just because there is already a specification for a web framework
(JSF) that does not constitute abandoning a standard approach. Look at
JAX-WS vs JAX-RS. They accomplish many of the same objectives, but they
both are part of the proposed profile stack
(http://www.theserverside.com/tt/articles/article.tss?l=JavaEE6Overview)
. A Wicket implementation could orchestrate a refreshing alternative
approach to JSF in the same manner that it does today.

When I referred to open-mindedness I was referring to being open-minded
to the ideas behind the push... I didn't necessary intended to imply
that anyone would not be open-minded if they did not support a JSR :o)

Unfortunately, those 'idiotic managers' (and I'm not disagreeing with you)
hold the purse strings. The move to Apache was a big step towards acceptance
by the business types. If you try to sell a new technology with a weird name
to your manager, it's not helping that there are just some guys from the
internet behind this (let's not argue whether that really matters or not,
it's just about the impression it gives).

Let's just say this: there are at least two angles to selling a particular
technology: the business angle and the technical merits. While the technical
merits of Wicket are evangalized, the business case is less promoted.

question we need to ask ourselves from a management standpoit is if for
whatever reason we had to migrate from Wicket to another framework, what

In many scenarios we have multiple languages that should have the same

However, this is not the optimal way and I don't think variation is made for

Every time I'm dealing with multiple languages the user wants bold, italic,
color in the text. Many times a list will appear just containing text. (

This could be added in a properties file but then we would have bold tags,
italic and style tags in the properties file. If something should change we
need to go thru 14 properties files to change the markup in the properties.

Let's say we have the following text in many different languages. Some
markup is changed so you know what I mean.

boldWelcome to our company/boldbrbrHere is some long
text.ullisome [BOLD]text[/BOLD]/liliother text/li/ul

Now imaging this text to be very long.

Now, my question is this. How do you handle tagged markup for different
languages without repeating markup tags.

* Variation and the text in the html file.
* different properties file with markup in it
* Other technique?

Re: What's your take on handling markup in properties, html, wicket

2009-02-13 Thread Jonathan Locke

Ideally the markup should stay in the markup file and the text in that
markup that needs to be localized would be localized via wicket:message and
a properties file. In cases like below, you would break the text into
properties-localized hunks and into panels with multiple markup localization
files where markup is truly being localized (you have little other choice if
the styling needs to be localized). How that's split up is up to you. In the
example you gave, maybe:

boldwicket:message key=welcome//boldbrbrwicket:messsage
key=longText/
div wicket:id=bulletPanel/

welcome=Welcome to our company
longText=Here is some long text

BulletPanel.html_en
wicket:panel
ullisome [BOLD]text[/BOLD]/liliother text/li/ul
/wicket:panel

i would generally try to avoid putting much markup in properties files since
that's a surprising use of properties files.

We use a combination of the following for that sort of l10n/i18n.

1. wicket:message
2. A Label with a StringResourceModel, and setEscapeModelStrings(true)
3. Fragments

Re: Correct way to deal with serialization and casting

if you add a private variable that is imodel you have to detach it
yourself, perhaps that is your problem. you do this by overriding
ondetach() { field.detach(); super.ondetach(); }

 Ok, feedback on my own problem. It seems that if you create a private

 It seems that the approach below doesn't always work in wicket.

 4. Line 9: Rather than call EditWebPage with a generic IModel and do the

 As for the wicket homepage, this would fit into the wiki if it's not

 If you can I'd suggest you use maven as your build and dependency

 Hello,



 I am in the process of evaluating Wicket for an upcoming project and in the
 process of writing some proof of concept code. Or trying to anyway. The
 problem I am having is that I keep getting the exception:



 java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

 after deploying and attempting to run the application.



 According to the Wicket quick start all I need to do is:



 You cannot use Wicket without adding an SLF4J logging implementation to
 your classpath. Most people use log4j. If you do, just include
 slf4j-log4j12.jar on your classpath to get Wicket to use log4j too. If you
 want to use commons-logging or JDK14 logging or something else, please see
 the SLF4J site for more information.



 The following jars are on my classpath:



 -  log4j-1.2.15.jar

 -  slf4j-log4j12-1.5.6.jar

 -  wicket-1.3.5.jar

 -  wicket-auth-roles-1.3.5.jar

 -  wicket-datetime-1.3.5.jar

 -  wicket-extensions-1.3.5.jar

 -  wicket-objectsizeof-agent-1.3.5.jar

 -  wicket-spring-1.3.5.jar

 -  wicket-spring-annot-1.3.5.jar



 Bear in mind that this is a NetBeans 6.5 project using apache-tomcat-5.5.23
 and JDK 5



 Am I missing jar a jar file(s) here that is not mentioned in the docs?



 I have tried to find the correct jar from the SLF4J distro but still no
 luck.



 Any suggestions are welcome!!!



 Thank you!

Re: Wicket at ApacheCon EU'09 in Amsterdam

swing like?
are there multiply implementations for swing?
Can i choose one from Sun and one from X?

or better said are there any desktop UI frameworks that do have multiply
implementations (for the same platform??)
not that i know of . There could be a reason for that

so your managers just want to program against interfaces.. And be able to
drop it into any container
i dont see the point. That makes testing only more horrible, every container
has its own bugs and slightly different behaviors...


Does anybody here on the list made a application using JPA persistence and
the first against hibernate and then when it was finished
swapped it for something else?

 Subject: Re: Wicket at ApacheCon EU'09 in Amsterdam

 
  From a developers point-of-view standardization can often be a thorn
  in our side, but for management it can offer a
  vendor-independent/implementation-independent solution.
  Maintaining/upgrading infrastructure is difficult, expensive and time
  consuming. From the point-of-view of management a standard can often
  minimize the risk of vender lock-in.



 But the examples you gave me have multiply implementations. But wicket
 doesnt have multiply implementations, what would that mean?
 That we have IComponent, IRequestCycle, ISession and IApplication and so
 on?
 And that IBM would make its own implementation of all the components
 including the base? And JBoss and X and Y?

 Answer: They do not have multiple implementations now, but they could
 potentially have them in the future. It would mean that other
 communities could follow a standard and mangement could be satisfied
 that Wicket has the backing of a recognized standard.

 There is no vendor locking for wicket.. (and all other open source web
 frameworks by the way) what is the locking?

 Answer: I agree that other frameworks that have a standard have been
 disastrous as far as portability between implementations (such as the
 loosly organized JSF specification), but the locking I'm referring to is
 in realation to the vendor (Wicket in this case) from a business
 standpoint. I for one do not have an issue with being tightly coupled to
 Wicket, but I can see why managment may have an issue with it. A
 question we need to ask ourselves from a management standpoit is if for
 whatever reason we had to migrate from Wicket to another framework, what
 revenue impact would that have on our organization in doing so? If we
 chose a standards base solution would this minimize the risk due to
 multiple vendor offerings?

 And wicket runs pretty much on all simple servlet containers.. Some bugs
 in some not counting...
 So give me a concreet example what a standardized wicket would look
 like.
 What vendor-independent/implementation-independent solutions there would
 be then..

 Answer: This is a preliminary concept, but the Swing-like architecture
 for the web could be a starting point?


 
  Another thing to consider is that a broader multi-community
  involvement could also bread innovation. There may be other innovators

  from other communities that may have valuable input that could improve

  Wicket in ways that may have not been previously considered. IMHO, the

  biggest argument for JSR/JCP is that there is often a broader
 involvement in the process.
  Hibernate, for instance, was in a similar position a few years back
  when they introduced a new persistence concept. They have since become

  heavily involved in the JPA specification process. When I first worked

  with Hibernate, like many, I was very impressed (similar to the first
  time I worked with Wicket :o), but looking back at how Hiberante
  initially did things to how they do them now there are some huge
  improvements due to the JPA specification.
 
 
 look hibernate is an implementation of a persistence.. And they adapted
 (and where involved) into the specifications yes
 Ok now translate that to wicket..
 What is wicket an implementation of? a webframework? ahh.. tapestry is
 also a webframework and struts is also a webframework
 They all implement the standard webframework spec.. which is the servlet
 spec..
 So

 JPA Spec == Servlet Spec
 Hibernate == Wicket
 TopLink == Tapestry

 So wicket is already in the JSR/JCP ! we are an
 enhancement/implementation of the servlet spec :)
 ok ok. Maybe you say.. sevlet spec implementation == servlet .jar and
 tomcat  ;) not the thing you would build on top of that again
 But then if you have wicket,tapestry and struts (and x and y) and then
 you want to define a Web Framework spec that all of them can adapt to
 what would that then be? What would that then gain? Would that mean that

Re: HTML can't reference a component (Label) multiple times?

not to mention it doesnt make sense for a lot of usecases, eg

2009-02-13 Thread moontz


i tried that before.  did not work.  no compile or runtime errors, but the
source did not show the change.

im thinking, since its an ajax link and because only the target panel
refreshes, the change to the link is not applied because the actual link is
not refreshed.  only the other panel is.  in which case i would need to
append javascript.  i was hping there was a pure wicket solutioin though
without using JS.

Re: Wizard Custom Layout example

2009-02-13 Thread John Armstrong

Thanks Igor,

I am already subclassing the wizard so that I can dynamically add
steps based on entities in the object. I also have overridden the
newButton(string) etc but the more subtle interactions are not clear
to me.

For example, I override newButtonBar(string). I get the basic table
markup with my panel injected but now I need to dig in and locate how
wicket is expecting the next/prev/finish/cancel buttons to be
presented and provide ID's for those etc.

Its not a huge problem and it will only take a few hours to dig
through the resources and see what is expected. I was just hoping for
a canned example. Sounds like that doesn't exist so I'll spend some
time and create one.

Thanks!

swing like?
are there multiply implementations for swing?
Can i choose one from Sun and one from X?
or better said are there any desktop UI frameworks that do have multiply
implementations (for the same platform??) not that i know of . There
could be a reason for that

Answer: Swing-like is referring to the programming model style- not
the actual Swing framework (thus the word like :o). However, there
could very well be other implementations for Swing, but that is another
topic altogether. One of the reasons why you don't see multiple
implementations of Swing is that it is part of Sun's Java Foundation
Classes (JFC)- web frameworks are not ;o)

so your managers just want to program against interfaces.. And be able
to drop it into any container i dont see the point. That makes testing
only more horrible, every container has its own bugs and slightly
different behaviors...

Answer: The reasoning that every container has its own bugs and
slightly different behaviors is the very reason why management may want
the flexibility to change implementations (the purpose for the standard
in the first place). One implementation may not implement some features
as well as others.

Does anybody here on the list made a application using JPA persistence
and the first against hibernate and then when it was finished swapped it
for something else?

Answer: It is highly plausible that a switch would be made from one JPA
implementation to another. I know of companies that have switched from
Hiberante to OpenJPA to do just that. Other reasons may include, but are
not limited to: better support from one vendor to the next, discounted
support through partner programs, light-weight implementation, etc.

  From a developers point-of-view standardization can often be a thorn

  vendor-independent/implementation-independent solution.
  Maintaining/upgrading infrastructure is difficult, expensive and 
  time consuming. From the point-of-view of management a standard can 
  often minimize the risk of vender lock-in.

 But the examples you gave me have multiply implementations. But wicket

 doesnt have multiply implementations, what would that mean?
 That we have IComponent, IRequestCycle, ISession and IApplication and 
 so on?
 And that IBM would make its own implementation of all the components 
 including the base? And JBoss and X and Y?

 Answer: They do not have multiple implementations now, but they could 
 potentially have them in the future. It would mean that other 
 communities could follow a standard and mangement could be satisfied 
 that Wicket has the backing of a recognized standard.

 There is no vendor locking for wicket.. (and all other open source web

 frameworks by the way) what is the locking?

 Answer: I agree that other frameworks that have a standard have been 
 disastrous as far as portability between implementations (such as the 
 loosly organized JSF specification), but the locking I'm referring to 
 is in realation to the vendor (Wicket in this case) from a business 
 standpoint. I for one do not have an issue with being tightly coupled 
 to Wicket, but I can see why managment may have an issue with it. A 
 question we need to ask ourselves from a management standpoit is if 
 for whatever reason we had to migrate from Wicket to another 
 framework, what revenue impact would that have on our organization in 
 doing so? If we chose a standards base solution would this minimize 
 the risk due to multiple vendor offerings?

 And wicket runs pretty much on all simple servlet containers.. Some 
 bugs in some not counting...
 So give me a concreet example what a standardized wicket would look 
 like.
 What vendor-independent/implementation-independent solutions there 
 would be then..

 Answer: This is a preliminary concept, but the Swing-like architecture

 for the web could be a starting point?

Re: Wicket at ApacheCon EU'09 in Amsterdam

2009-02-13 Thread Dave Schoorl

I do think that pushing a JSR for Wicket will have a negative influence 
on the spirit of Wicket and it's community due to the politics involved 
with a JSR. Politics are so not the Wicket way. This is what I mean with 
the wrong way and yes, that is mighty subjective.


I also expect there will not be enough support from other parties to 
participate in a JSR (again, highly subjective), because there is 
nothing for them to gain. Which I believe is one of your main arguments: 
there will not be a broader input base. But I think Wicket receives 
enough input since the Wicket developers see what is happening in other 
projects around them and they take that with them.


And without enough support, the JSR will be dropped and I think that in 
the corporate eye, Wicket will turn into 'that project that didn't make 
the JSR', and wide adoption will be even further away.


But again, without a concrete proposal, I have no idea what the 
specification request would describe and what the scope of such a JSR 
would be. Could you elaborate on that? Maybe that clears things up for me.


BTW, I think not that Hibernate has grown as a result of the 
JPA-standard, but that the Java EE standard has grown a a result of the 
emerging of ORM-tools (like Hibernate, Toplink etc.) and other popular 
application stacks, like Spring etc. The quality of Hibernate would have 
increased without the JPA-spec anyway (and ofcourse, there was - and 
there still is - enough opportunity to improve).



Hoover, William wrote:

I agree that we need to change the views of corporate managers in the
right way by illustrating the cost savings achieved though a reduction
in development time. At the same time, I don't believe that this will
change the Wicket community in the wrong way (which is a highly
subjective statement). I'm only presenting the alternative viewpoint. It
is possible that a standard could potentially inhibit progression due to
contrasting viewpoints within the community, but it is also equally
possible that it could lead to a value-added aspect by introducing a
broader input base to the Wicket community that could speed progression
(Hibernate/JPA is an example of this). There is always a possibility
that progress can be slowed as the number of members increase because
there are more viewpoints to be examined/debated. I think that there is
a higher probability that the community will grow if such a standard
were to be adopted.

Just because there is already a specification for a web framework
(JSF) that does not constitute abandoning a standard approach. Look at
JAX-WS vs JAX-RS. They accomplish many of the same objectives, but they
both are part of the proposed profile stack
(http://www.theserverside.com/tt/articles/article.tss?l=JavaEE6Overview)
. A Wicket implementation could orchestrate a refreshing alternative
approach to JSF in the same manner that it does today.

When I referred to open-mindedness I was referring to being open-minded
to the ideas behind the push... I didn't necessary intended to imply
that anyone would not be open-minded if they did not support a JSR :o)

I am not sure what you would like to standardize. Given your JPA
example, I would guess that you want to push a JSR for a web framework
or something. But there is already something like that: JSF. Just let
Wicket be Wicket and instead of changing Wicket (and it's community) in
the wrong way, let's try to change the views of corporate managers in
the right way. As Thomas said earlier What we need is less talks titled
'why wicket is cool' and more 'cut your development costs in two with
Wicket' .

Re: What's your take on handling markup in properties, html, wicket


It would be a lot of split ups in the properties files and a lot of
wicket:message but I guess it is the best way when separation markup from
pure text. 

This is always a problem. I'm dealing with the same concern when a user
want's to add html markup to a news that is saved in the database. 

The best way would be to always have pure text and then some aspects on
marking it up but I don't see how that could be accomplished.

 According to the Wicket quick start all I need to do is:



 You cannot use Wicket without adding an SLF4J logging implementation to
 your classpath. Most people use log4j. If you do, just include
 slf4j-log4j12.jar on your classpath to get Wicket to use log4j too. If you
 want to use commons-logging or JDK14 logging or something else, please see
 the SLF4J site for more information.



 The following jars are on my classpath:



 -  log4j-1.2.15.jar

 -  slf4j-log4j12-1.5.6.jar

 -  wicket-1.3.5.jar

 -  wicket-auth-roles-1.3.5.jar

 Bear in mind that this is a NetBeans 6.5 project using apache-tomcat-5.5.23

 Am I missing jar a jar file(s) here that is not mentioned in the docs?



 I have tried to find the correct jar from the SLF4J distro but still no

Re: Setting TreeState in new page

2009-02-13 Thread Seven Corners


Never mind, I figured it out.  Caching the TreeState didn't get me there
because it didn't contain the information I needed.  I had to do my own
bookkeeping, but overriding LinkTree.newTreeState() was ultimately where
things got set aright.

Re: FormTester selectMultiple CheckBoxMultipleChoice help

On Wed, 11 Feb 2009, ray bon wrote:
 I am trying to test the case where a user is changing the set of checked

 How do I get FormTester to unselect values?

Sounds like a fair enough feature, could you please add a 
Jira issue?

Meanwhile you can do

  formTester.setValue(checkBoxMultipleChoice, );

in between to get the values reset.

E.g. this works in FormTesterTest as far as I can tell:

public void 
testSelectingMultipleCheckboxesAfterSubmitResetsPreviousSelections()
{
assertBooksEquals(new Book[0], 
choicePage.checkBoxMultipleChoice);

formTester.selectMultiple(checkBoxMultipleChoice, new int[] { 
1, 0, 3 });
formTester.submit();

assertBooksEquals(new Book[] { books[0], books[1], books[3] },
choicePage.checkBoxMultipleChoice);

formTester = tester.newFormTester(choiceForm);
formTester.setValue(checkBoxMultipleChoice, );
formTester.selectMultiple(checkBoxMultipleChoice, new int[] { 
2 });
formTester.submit();

assertBooksEquals(new Book[] { books[2] },
choicePage.checkBoxMultipleChoice);
}


 I know I can look at the source code and extend this class, but this seems
 like an awkward solution for what appears to me to be a very common use
 case.

I don't think that it's so common, though. With WicketTester 
tests, it's more normal to have the very small and focused 
and not submit different selections.

If you're doing something on each selection, it should typically
be Ajax and then you should be doing executeAjaxEvent()s anyway.

Best wishes,
Timo

Re: Checkbox OnChangeAjaxBehavior with defaultFormProcessing=false??

On Thu, 12 Feb 2009, Martin Makundi wrote:
 1. I have a form
 2. The form has checkboxes
 3. The form has other fields
 
 The checkboxes are used to disable specific fields in the form.
 Whenever the user changes the checkbox state, I want to use
 AjaxEventBehavior or similar to update the form components dependent
 on the particular checkbox (just to set them enabled/disabled).

If you repaint the component from the server, and want to
retain its input, you have to submit to the server and store
it to the model (with a suitable *submittingbehavior) so
that it will have the correct value on the repaint.  Because
the Ajax response content always comes directly from the
server it has only access to submitted data. So, if you have
one checkbox that toggles several input elements, you must
use a behavior that submits the whole form.

Another option is to do it purely on the client side --
toggle the input DOM element properties with javascript 
attached on the correct event handler (onclick I think?)
of the checkboxes. Your favourite Javascript library (e.g.
http://acko.net/files/jQuery%20-%2023%20March%202007.pdf )
can come handy there.

Timo

Maybe a conversion error that prohibits updating the model?
Though in the case of validation or conversion errors the 
erroneous input could be preserved... but maybe the Ajax 
update gets it from the model anyway?

0) raw input
1) convert - if succeeds, convertedInput
2) validate - if succeeds, model

Do you have a feedback panel on the page?

By debugging Form.process() you can probably see easily 
what's going on.

 I feel it is more consistent to use just plain Wicket.

In a way, yes, but sometimes purely client-side stuff can be
easier purely on the client-side.

RadioGroup in a DataTable?

Is it possible to have a RadioGroup in a DataTable. I am trying to display a
list of items from the database and I want the user to only select one of
these items. There could be a lot of items so I am letting the user filter
the values by using a FilterForm and a DataTable. 

Any ideas?

How to setResponsePage across frame based on Ajax

In Tree class, I override onNodeLinkClicked() method to setResponsePage,
when I click on the tree node.

to update the frame outside the current frame, It will not work, because the

is based on Ajax, it cannot update the frame outside, only if I refresh the
browser.
