Like this maybe?
public class MySession extends AuthenticatedWebSession { ...
public class MyApplication extends WebApplication {

@Override
public WebSession newSession() {
return new MySession();

Re: Quite a few Wicket jobs/employers.
... I think there's a bit more substance to it than that as, iirc, many of the ads were talking about experience with component based frameworks, Swing etc ... ie they're interested in people who are more likely to be familiar with some of the underlying concepts and who will enjoy using Wicket, even if they haven't tried it yet.

validation with disabled parent
Hi gang,
Am I correct in thinking that having a parent component isEnabled() to
false does not prevent the children validation (1.3.0-rc1 for that matter) ?
I see in Form
public Object formComponent(IFormVisitorParticipant component)
{
if (component instanceof FormComponent)
{
FormComponent formComponent = (FormComponent)component;
if (formComponent.isVisibleInHierarchy() &&
formComponent.isValid() &&
formComponent.isEnabled() &&
formComponent.isEnableAllowed())
{
validate(formComponent);
}
}
I would have thought at first glance that it did not make any sense to
traverse the components for validation if the parent is disabled.
side note: (Also for personal knowledge, is there any reason why the
check for visibility is actually backward for traversal ? validation is
occurring by traversing the tree top down, so I would have think in
theory that stopping the traversal would be enough to avoid having each
component doing a bottom top check in isVisibleInHierarchy(). I suppose
there is a reason for that (haven't checked yet the formvalidators logic
to see how components are treated, if they are iterated over I guess
that can explain while they all need to traverse the parent hierarchy)
I see in the same code that to avoid traversing the children I can make
use of the method processChildren() to stop the traversal.. that's what
I did right now, but I'm not sure if this is really the intent or if
it's just a hack.
(basically I have a component (containing other components) which is
enabled based on a checkbox input (which enable-show/disable-hide the
children components through javascript), so I end up testing the water
with something like:
MyParentComponent my = new MyParentComponent("test") {
public boolean isEnabled() {
return radio1.getMarkupId().equals(radiogroup.getInput());
}
public boolean processChildren() {
return isEnabled();
}
};
That seems a bit 'hacky' and I wonder if the recommended way is not to
entirely make it wicketable with ajaxable component all around that
always do server round-trip ?
thanks

Re: Wicket-Seam Integration
Frank, This is precisely the type of information I was looking for, thank you. It may also give a few Wicket users more reason to have a play. My initial thoughts are in line with yours; this will probably be a bigger help to Seam users - who can now choose between Wicket's excellent and easy to use/extend features and the more cumbersome (but JEE "standard") JSF, than to the Wicket users. However, this new integration possibility is clearly not a bad thing for anyone concerned/affected anyway. Eventually, I expect the Wicket developers/users will discover/invent ways to benefit from some of Seam's features as well, even if it's only for its tight integration with jBPM (and Drools?) and of course, MDBs and SBs. The webbeans JSR's success will no doubt have some influence on this. Personally, I appreciate having such options (form a Wicket user perspective) and thank you for making such an integration/possibility available.

I didn't see it from this point of view before. Yeah. Like I said, officially GET requests should be idempotent. And that's fine when you talk about documents but hardly makes sense when you think about applications. Even if you avoid state changing things like deleting records with links, you still have to deal with things like data that might get stale between requests. So personally, I think the idea of having idompotent web requests as part of user interfaces is flawed to start with.

Re: disabled AjaxEditableMultiLineLabel
i found the "problem":
what i mentioned before with onBeforeRender didn't make it into rc1. sorry
for messing that up.
but now there are two checks for enabled/disabled.
i actually prefer the one with dis-/enabling the label in onBeforeRender,
because this way the onClick attribute doesn't even get rendered,
whereas with the second approach there's an ajax roundtrip which is
basically in vain, since nothing will be done anyway...
Al, if you don't mind, i'd like to remove the check in
AjaxLabelBehavior#onEvent again.

Re: How to instanciate panels best?
here's a component solution to panel caching (with a couple of caveats):

i don't think it would be a great idea to use this component much, but
there are definitely places where it might be very convenient if you have
high traffic and know what you're doing.

Dear Wicket Team,
First of all, let me say that Wicket is the best thing in Java Web
development today! It really brings Java back to be a first choice when
creating Web applications. Thanks for your development efforts :)
I have a question regarding the instanciation of panels of which I have
a huge number placed at top, bottom , left side and right side of a web
site, and that should be shown again on any page of the side. This is a
very common design I guess. I was browsing the documentation and the
mail archive, but didn't really find a solution concerning the
instanciation.
This is the scenario:
- I have a template page, that all other pages I create are extending.
- This template page defines a number of panels (menu at the top,
statistics and pictures at the left side, dynamic messages at the right
side, ...), and for sure an area for the main page content using
"wicket:child" approach.
- The panels read data from the internet, and from a database, but
their content does not change very often. Consider e.g. showing user
statistics of how many messages he/she posted. This does only change
when really a new message was posted.
The problem:
- Whenever a page is requested, the template page instantiates all
panels using "add(new Panel("nameX"))". The panels do again read data
from the internet, and from the database.
This is not very fast, and it appears to me that the processing power
and memory consumption for this might be high. Imagine thousands of
users using the web site.
I guess the approach I have chosen is not the best solution. The pages
have models behind any way, so they know their data, they don't have to
be reconstructed all the time. I have this behaviour e.g. when I submit
a form, and no new target is given - the page is reconstructed without
instanciating all panels again, it just renders all panels with the
data coming from the models behind.
*** What is the "best practise" to not instanciate "page aggregating
panels" all the time? ***
I had the following ideas:
- Using the user session to store my page object references to check if
a panel is already instanciated and then just use the reference instead
of doing a new?

Re: Rendering strategies question
Wicket will redirect all event listeners so you don't get double clicks as well. For instance a link to edit some item takes you to an edit page. If you do a onepass render, the event listener will be called each time the user refreshes the edit page. This means that the edit page is created each time and any operations that are part of the event listener will be executed as well. However with the redirect to buffer, the user is redirected to a stable URL, and remains on the edit page. When he refreshes the page, the edit page is fetched from the page store and rendered again. No event listeners are involved here.

Because proxies are not outjection frendly in this case. Pardon me for maybe not getting it, but I don't really understand how outjection would help Wicket developers. After all, everything works with regular Java objects, so when I did the first pass of Seam integration, I didn't really see the use case for 'exporting back' values to the seam context. Isn't it enough to change the values (which are passed by reference) if you want to have changes applied? I somewhat understand the merit of outjection if you pass around request parameters from request to request and if you don't work with a construct like Wicket's models, but I'm missing the benefit of outjection for Wicket applications. Would it be possible to give us a short primer on what outjection is and what it is good for when building Wicket webapps? > 3. Because it is important that you can inject/outject null references. Why is that important? If it is memory consumption, those proxies null their references at the end of a request.

Like Al hinted, you should not try to use the old panel again, but
instead focus on more fruitful forms of optimization. The construction
of Wicket components isn't very expensive in itself. What typically
makes it expensive is the data you expose through it, either using
models or directly. So what you should do is cache/ reuse the data
where you can, so that you avoid database round trips and other
expensive processing.
Often, the best thing to do when it comes to optimizing is to use a
profiler (YourKit for instance). Optimizing without using a profiler
to determine what the bottlenecks probably means you're optimizing the
wrong things.

Re: How to instanciate panels best?
of course, this only caches the rendering of a component within a session.
and it would only work for components with a fixed path. i'm not sure
what it would mean to cache the results of a component globally.
with a fair amount of magic, you might be able to create a CachingPanel
component in the existing wicket. you'd take over the rendering process,
and render self based on class identity and interval. that would certainly
be a less invasive approach.
it may be that all these things are best left out of wicket, but it can't
hurt to
think about it a bit.

Re: How to instanciate panels best?
actually one way to solve this that would not involve changing wicket's
session
model would be to do what that thread suggested in terms of caching:
/**
* @return Duration between renders of this page or null to always render
*
*/
protected Duration getRenderInterval()
{
return Duration.ONE_MINUTE;
}
just put that method on Component instead of Page. the rendered markup
would naively be cached in Component along with the time the component
was last rendered, but the better place to do it would be in Session, keyed
using the Component's path and time of last render. The cache in Session
would only need to be checked for Components that override
getRenderInterval().
can someone remind me why we haven't done this? I can't even open the
Page.java file on my Mac without Eclipse crashing, thanks to Apple.

session and application scope components are not supported in wicket up to
1.3
(they will not work).
this idea is really a request for more "static" components, like this

Rendering strategies question
Hello Wicketeers, I prepare report about rendering strategies (for studying community in our company) and conceptually I understand all the things, but I have one question, that I cannot answer. The default rendering strategy is RENDER_TO_BUFFER, because it solves both problems of two previous strategies: 1. no double submit problem 2. no potential problems with double attaching/detaching models But in my mind, I have problem: When some aplication has 90% of pages, that are only for viewing, and 10% of pages, that submit form, then I see, that for 90% of the view pages is the redirect not useful. For these 90% pages would be sufficient only ONE_PASS_RENDER strategy, because there is no need for redirect from my point of view. Only 10% of pages takes advantage from redirecting. Does'nt it make 90% of needless redirects ? Is it not possible tu use REDIRECT_TO_BUFFER strategy only for POST request, and for all GET request respond with ONE_PASS_RENDER ? But in WicketFilter all POST's call GET, so I think it's not possible. Is there anything I forgot to think about ?

Re: How to instanciate panels best?
Hello all,
I try to explain my question using sourcecode ;)
Imagine:
MyTemplate.java
public abstract class MyTemplate extends WebPage {
public MyTemplate() {
add(new MyPanel("myPanel"));
}
}
MyTemplate.html
MyPage.java (html is trivial, using wicket:extend)
public class MyPage extends MyTemplate {
...
}
MyPanel.java
public class MyPanel extends Panel {
public MyPanel() {
// THIS PANEL IS RECONSTRUCTED ON EACH MyPage REQUEST
// BECAUSE MyPageTemplate DOES A new MyPanel...
}
}
What could I do to use the old panel again? Do I really have to care about
the panel object reference by myself, i.e. store is to the user session,
check if it is there, if yes then retrieve, if not the do a new, etc.? I
don't have to, do I? The Panel is in the wicket session anyway, and the user
session would grow too much, leasing to the StackOverflowError I already had
...
I hope you can help me, thanks in advance :)
Kind regards,
Bernd

Re: Getting started
Ho.. yes it is possible. .. really i'm a stupid boy !
But is it also possible to give one model for all content of the page ?
public class MyPage extends WebPage {
public MyPage(PageModel model) {
add(new Label("welcome", model));
add(new ExternalLink("toGoogle", model));
}
}
Maybe, this klind of model already exist ? If not what existing model
can i extend or implements to do that ?
Also is it possible to give objects to page by a setter ? I suppose that
it isn't beacause page was rendered after the constructor.

Thats how i do it, may be i don't understand your problem correctly,

add(new Label("message1", foo.getMessage1()));
add(new Label("message2", foo.getMessage2()));

Re: Ajax File Download with Form Process and Result Refresh
A regular form and an ajaxbutton should get you a long way. Assuming
you have a feedbackpanel on your page.
The onSubmit of your button should do something like:
onSubmit(AjaxRequestTarget target)
{
//do calculation
target.addComponent(getForm());
//somehow create and or upload pdf
}
onError(AjaxRequestTarget target)
{
//refresh feedback to show feedback messages
target.add(feedbackpanel);
}
Now if someone else can explain the best way to serve a file from or
after an ajax call.
I think you have to use a regular request for that but who knows :)

Let me explain my point of view: * From a Wicket application developers perspective: Pros: 1. Separation of concerns: Move all business logic to the "Seam layer". So Wicket code manages only the view. - For example: You can develop many "Wicket views" (html, wml, ..) all they bounded to the same loosely coupled "Seam layer" 2. Easy decoupled access to EJB3.0, JNDI Resources, Web Services and JBPM Engine. Cons: More dependencies, more layers (this is not a con from my view, but may be for others) * From a Seam application developers perspective: Pros: 1. Kicking off JSF and use the great Wicket component model. Cons: 1. JSF is well known and has many component libraries, but Wicket is a new API to learn. * About WebBeans JSR-299: I Think it will be the final standard solution for these things, but i thought the same about JSF and some years after it, i am moving to Wicket now. :) Cheers, Frank. -- Frank D.

Markup variants on component level
Hello Wicketeers, I read about markup variants on the wiki [1]. I need this, however I need it on component level rather than page level. Is this possible? In the most extreme case I would like to have different instances of the same component on one page, but each with their own markup variant. The workaround I use right now is extending my component with an empty class for each variant.

Getting started
Hy all, I'm new in the famous wicket world ! I need to start learning Wicket but i can't found docs that explain more than just doing a HelloWrold or a GuestBook. In fact i need to use Wicket with Spring but for that i first need to understand and play with wicket. So i have many questions. 1° Is there a way for stupid frenchies that don't speak english like me to talk about Wicket ? (If not sorry for my poor english) 2° How can i import other page. Like a <%@ include file="includes/menubar.inc.jsp" %> or page="includes/menubar.inc.jsp" flush="true" /> tag ? 3° In a big form ( with more than 20 fields ) that represnet more than one Pojo Bean how must i work ? Thanks
Re: Wicket-Seam Integration
Frank, Since this is the mailing-list for all things, technical and non-technical, related to Wicket, from *a Wicket application developers perspective* what are the main benefits of introducing the complexity of Seam to a project in terms of development/maintenance/extensibility/support etc into a Wicket web-app project (bijcetion/conversations ...?) as opposed to the benefits of using Wicket on Seam projects (which is presumably the chance to use Wicket and its great component model in place of JSF as the view technology ??). I notice that the webbeans spec ( http://jcp.org/en/jsr/detail?id=299 JSR 299 ) is coming along now - presumably this spec looks quite a lot like the Seam mission-statement. Again, what are the implications (and pros/cons/opportunities, if any) for Wicket based projects?

You /really/ need to learn how to work things out for yourself. Allow me
to lead you through such a process.
So, you want something similar to onclick in an AjaxLink...
Let's see, it's similar to AjaxLink...
Oh, I know... Why don't we go and see how AjaxLink works?
Hmmm, that looks pretty compact and simple. Oh, look; all the work is
done in the constructor, where we add something called an
"AjaxEventBehavior" for the "onclick" javascript event.
It looks like onClick() for the AjaxLink is called by the onEvent()
function in that behavior. Hmmm... I wonder how that works?
Oh, look, in onComponentTag() we put an attribute into the HTML tag. The
name is pulled from the "event" variable (so "onclick" for the AjaxLink)
and the value of the attribute is the return value from getEventHandler().
I wonder where getEventHandler() comes from and what it does?
Ah, it just calls getCallbackScript().
That's not in this class - it must be in the super class.
Oh, yes, look - it's in AbstractDefaultAjaxBehavior. Maybe I can just
use that?
AbstractDefaultAjaxBehavior behavior = new AbstractDefaultAjaxBehavior() {
protected void respond(AjaxRequestTarget target) {
// Do stuff here.
}
};
Then in my Javascript for the page I can just invoke the JavaScript
generated by behavior.getCallbackScript();
Yes, mmm, that seems to work.
That wasn't so hard to work out, now, was it?
Regards,
Al

Re: Wicket Stuff JQuery + Wicket Ajax
Hi all, Please ignore this mail, i found the reason why it was not working. just calling target.appendJavascript(dnd.getJSFunctionName4Start() + "();"); will do the trick. I had an idea its about calling nd.getJSFunctionName4Start(), but i tried it in a wrong way, instead of appending i tried using AjaxCalldecorator.

Re: how to generate a javascript function
You can do the following:
override the getAjaxCallDecorator() method of AjaxLink component.

Re: how to generate a javascript function
Wicket generates the link as follows:
# info page
And if I put the "onclick"-content to my javascript function sometime it
works
and sometime I get an error.
The reason for this is probably that Wicket increases the value of the
wicket:interface
It starts at 0 (...('?wicket:interface=:0:...) and is increased.
Therefore, I thought of the dynamic creation of the function.
Or is there another solution?
Thanks,
Heiko

If I interpret your answer correctly, this means that the way my page is composed and the panels are instanciated is "the Wicket way", I mean, correct. Ok, what I could do then, is creating Spring managed singleton beans (I work with a Wicket/Spring/Hibernate environment) - or at least one - that gather the data for me, and let my panels request the data from the Spring bean. So this somehow means I do the caching on my own, to fill the panels efficiently, but if this is how it has to be done using Wicket, I will go that way without thinking I am doing something unelegant.

Icy wrote: *** What is the "best practise" to not instanciate "page aggregating panels" all the time? *** This isn't really a Wicket question. Your page is slow because doing database/remote operations is slow. It has nothing to do with creating Panels, but everything to do with the database access you're doing in the constructor of those Panels. You need to break those operations out into a service layer that can cache the results, then use that service layer in your constructor.

Jasypt + ICrypt + ICryptFactory
Hello everyone,
I am about to release a new version (1.4) of Jasypt [http://www.jasypt.org],
and I am considering the addition of some wicket integration features for
improving wicket's encryption capabilities.
But I would first need to ask a couple of things :-)...
First, what I will do (have already done, in fact): I have added to jasypt
both an implentation of the org.apache.wicket.util.crypt.ICrypt and
org.apache.wicket.util.crypt.ICryptFactory interfaces. The idea is to use
JasyptFactory as the desired ICryptFactory implementation for the
application, like this:
--(CODE WHICH WOULD GO INTO OUR "WebApplication" CLASS)--
@Override
protected void init() {
super.init();
/*
* In the following code example we will create a Jasypt byte
* encryptor by hand, but in real world we can get it from Spring,
* configure it via Web PBE configuration... whatever we want to.
*/
StandardPBEByteEncryptor encryptor = new StandardPBEByteEncryptor();
encryptor.setAlgorithm("PBEWithMD5AndDES");
encryptor.setPassword("jasypt");
/*
* Create the Jasypt Crypt Factory with the desired encryptor,
* which will return org.jasypt.wicket.JasyptCrypt objects
implementing
* the org.apache.wicket.util.crypt.ICrypt interface.
*/
ICryptFactory jasyptCryptFactory = new JasyptCryptFactory(encryptor);
/*
* Set the Jasypt Crypt Factory into the application configuration.
*/
getSecuritySettings().setCryptFactory(jasyptCryptFactory);
}
But the question here is... what is the real use of the ICryptFactory today
(1.3.0-rc1) in wicket? Is it "only" encrypting URLs? (I see
PasswordTextFields are not encrypted anymore)
And if so, would it be of real use/need? Of course, It would increase much
(as much as Java can) the security of the URLs' encryption but, would you
see any other uses?
If this is only used for encrypting URLs, and if I am not wrong, our
"WebApplication" class would also need something like this:
--(CODE WHICH WOULD GO INTO OUR "WebApplication" CLASS)--
@Override
protected IRequestCycleProcessor newRequestCycleProcessor() {
return new WebRequestCycleProcessor() {
@Override
protected IRequestCodingStrategy newRequestCodingStrategy() {
return new CryptedUrlWebRequestCodingStrategy(new
WebRequestCodingStrategy());
}
};
}
Would this be correct/adequate?
And more important: can I consider wicket's ICrypt and ICryptFactory
interfaces *stable*? (at least until a stable 1.3.0 release). Have you got
any short-term plans for changing anything in this encryption
infrastructure?
And the last thing: the "setKey()" method in ICrypt is not usable in Jasypt,
as encryptor configuration and initialization is quite more complex and PBE
keys (encryption passwords) cannot be changed once an encryptor has already
been initialized (password is set on the jasypt encryptor, not the
wicket-friendly JasyptCrypt).
So, JasyptCrypt will always throw an exception if this method is called.
Currently in wicket, "setKey" is only called from
org.apache.wicket.util.crypt.ClassCryptFactory, which jasypt does not
extend, so this would not pose any problems for the future, but... could it
make sense that that "setKey" method were called by the developer anywhere
else? this would render jasypt integration quite complicated...
Sorry for the size of the message and the lot of questions :-)
Regards,
Daniel.

AuthenticatedWebSession
Hi,
In setting up the logon of our application, I'd like to use the
AuthenticatedWebSession to hold some additional information. There shouldn't be
a problem with that I assume, however I'm getting a problem with this.
It seems the session isn't created until the user encounters an
@AuthorizeInstantiation("..."), but there are parts of the page which doesn't
require authentication and thus no session for me to use. Is there a better
strategy for containing the business layer main object, or a way to ensure that
the AuthenticatedWebSession is created at the same time as the Application?

Conversion Error Messages
Hi Guys, I would like to ask help on something. I have a text box which accepts the field which is supposed to be a double. everytime that a user enters a field that isn't a double the error message 'Field is not a valid double' appears. However I want it to display a different error message this time. I'm having trouble fixing it. How I can I make it display that 'Field is not a valid amount' ?

How to instanciate panels best?
Dear Wicket Team,
First of all, let me say that Wicket is the best thing in Java Web
development today! It really brings Java back to be a first choice when
creating Web applications. Thanks for your development efforts :)
I have a question regarding the instanciation of panels of which I have a
huge number placed at top, bottom , left side and right side of a web site,
and that should be shown again on any page of the side. This is a very
common design I guess. I was browsing the documentation and the mail
archive, but didn't really find a solution concerning the instanciation.
This is the scenario:
- I have a template page, that all other pages I create are extending.
- This template page defines a number of panels (menu at the top, statistics
and pictures at the left side, dynamic messages at the right side, ...), and
for sure an area for the main page content using "wicket:child" approach.
- The panels read data from the internet, and from a database, but their
content does not change very often. Consider e.g. showing user statistics of
how many messages he/she posted. This does only change when really a new
message was posted.
The problem:
- Whenever a page is requested, the template page instantiates all panels
using "add(new Panel("nameX"))". The panels do again read data from the
internet, and from the database.
This is not very fast, and it appears to me that the processing power and
memory consumption for this might be high. Imagine thousands of users using
the web site.
I guess the approach I have chosen is not the best solution. The pages have
models behind any way, so they know their data, they don't have to be
reconstructed all the time. I have this behaviour e.g. when I submit a form,
and no new target is given - the page is reconstructed without instanciating
all panels again, it just renders all panels with the data coming from the
models behind.
*** What is the "best practise" to not instanciate "page aggregating panels"
all the time? ***
I had the following ideas:
- Using the user session to store my page object references to check if a
panel is already instanciated and then just use the reference instead of
doing a new?
- Using some mechanism to get a panel reference from the wicket session,
where the page and models are stored anyway?
-> Both approaches require unelegant "manual work", for which I think Wicket
is offering something, as one of the main aspects of the Wicket framework is
page management.
- Using Spring to manage the Panels?
-> Is this wanted from the Wicket design point of view? And does it really
work?
Many thanks in advance for your help. Maybe I really missed it and this very
common problem is already explained somewhere.
Kind regards
Icy

Why i do not use proxies:
1. Seam injected Ejbs and JNDI resources are already proxies, so i
don't want a proxy of the proxy of the proxy ..
2. Because proxies are not outjection frendly in this case.
3. Because it is important that you can inject/outject null references.
What is supported by now:
1. Injection of seam components and context vars.
- You can inject resources based in its field/method name,
explicit name, type name, or even an EL expression.
2. Outjection
- You can outject things to the seam context using fields and methods
3. Evaluation of EL Expressions against all seam contexts:
- Using SeamContext.eval( expression )
- As a value of an @In annotation. for example you can use:
@In("#{personService.count()}") private Integer count;
4. Easy access to seam contexts (Read/Write):
- Using SeamContexts.set( ... ), SeamContexts.get( ... ),
SeamContexts.eval( ... )
What is not supported:
1. @Name annotation on Wicket pages/components is not supported (obvious).
2. Seam injection/outjection via annotations is only supported at
page level, but you can access seam context directly using SeamContext
class from anywhere.
Cheers,
Frank

Re: disabled AjaxEditableMultiLineLabel
This is the code (wicket 1.3 rc1)
add(new AjaxEditableMultiLineLabel("Comment", new
PropertyModel(experiment, "experimentDetailStat.Comment")){
/*
@Override
protected void onEdit(AjaxRequestTarget target) {
if(isEnabled()){
super.onEdit(target);
}
}
*/
@Override
protected void onSubmit(AjaxRequestTarget target) {
super.onSubmit(target);
Util.getBean(GenericLocal.class).saveObject(
experiment.getExperimentDetailStat());
}
}.setEnabled(LoginSession.get().isAdmin()));
and I tested by replacing the LoginSession.get().isAdmin() by false but I'm
still able to edit that field
