If you don't know them, that doesn't mean they don't exist :-)
We're also using OSGI with Wicket. We've made some changes to fix class loading 
issues and we use all the Wicket jars separately, with a generated manifest 
that explicitly imports and exports the right packages.
We still have to get around to clean up our changes and try to get them 
committed. One of my 'OSGI expert' colleagues wrote the stuff.

It would be a nice step forward to not have packages split across different 
Wicket jars. Some OSGI containers trip over this.

Not doing anything now because it can break in the future is not a really good 
argument..?
Anything can break, that's why there are unit tests, release candidates, 
etcetera.
With some small design improvements (no split packages, 'better' jar(s)) and a 
better manifest the 'Wicket OSGI support' will surpass many other frameworks or 
libraries.

BTW: to all the Wicket people: keep up the good work!

Re: Form tag in modal.js

Hi Frank,

You can use nested forms, so you can put a form inside your ModalWindow.
The  tag should not make a difference, or are you experiencing other 
problems?

wicket will not throw an error even though i never added the "foo"

the enclosures, however, as of 1.4.4 *will* throw an error for

Re: How to write markup if type of component is not known yet...

[Daan van Etten]

You have some options:

Write one abstract panel with the complex markup and extend the
read-only and editable panels from that class (wicket:child and
wicket:extend).

Or, create a panel with the complex markup and create two separate
panels to edit and read. Switch those panels from the
ComplexMarkupPanel, depending on which one you want to see.

We will hold our next London Wicket Event on Saturday, 21st  
November, from 14:45. This time we have hired "The Gallery" at the  
iconic Foyles Bookshop in central London.
We again welcome guests and speakers from several countries,  
including at least 3 core committers, Matej, Jeremy and of course,  
Alastair, as well as the founders of WiQuery (Wicket-jQuery  
integration), Lionel Armanet and his team.


Join us for some very interesting, high quality presentations and to  
chat with fellow Wicket users and developers at all levels. We're  
expecting this to be another popular event and since places are  
limited book and confirm early if you can make it. Details and  
registration are at the usual place [1].
There is a cool little Jazz cafe at Foyles too, where there'll be a  
live act (Femi Temowo) at 13:00 if you enjoy some Jazz guitar  
relaxation before your intellectual stimulation. They offer a decent  
range of food and drink there too.


The event schedule looks like:
Cemal Bayramoglu: Introduction
Jeremy Thomerson (USA): Custom JavaScript Integrations with Wicket +  
Auto Resolvers

Lionel Armanet (FR): Announcing WiQuery 1.0: Introduction & Demo
Matej Knopp (SK): BRIX CMS + Wicket 1.5 Developments Q&A
Alastair Maw (UK): The Al Talk
Our Regular General Wicket Q&A with Al and Cemal
We expect to formally finish by around 19:00. I would expect the  
usual suspects will be heading somewhere in the neighbourhood for  
refreshments straight after the event, and of course you are more  
than welcome to join us.

Re: Wicket tester test coverage

[Daan van Etten]

In my other post I gave a link to a full-fledged example which scans for
Panel classes with the default constructor and instantiates them.

http://stuq.nl/weblog/2009-11-01/automatically-test-your-wicket-panel-html-markup

This has almost no value (in my opinion) for reporting unit testing
coverage. It only checks for exceptions and if the code matches the
markup at instantiation.
An exception could easily be thrown when replacing panels, clicking on a
link or submitting a form. This is not tested.

Daan van Etten

Re: Wicket tester test coverage

[Daan van Etten]

Hi,

What you can do is scan all Page classes (or Panel classes, etc) on the
class-path and check if there are tests for them. 

Put this code in a unit test.
Fail the test if you find a class without accompanying test.

You can use this example to get started with the class path scanning:
http://stuq.nl/weblog/2009-11-01/automatically-test-your-wicket-panel-html-markup

Re: How to determine which validator failed in a CompoundValidator?

[Daan van Etten]

Hi,

I think you have to be sure that you do not send an unencrypted  
password across the wire...
That said, I think you can post back the value to the server and  
update the PasswordStrengthMeter with that.

Or you could use Javascript to make it all client-side.

It all depends on implementation if you could reuse classes from my  
blog post.
I think you can use standard Ajax behaviors to update the  
PasswordStrengthMeter. After that, you could use standard form  
validation to validate the strength of the password. With my code, you  
can display an error next to the password field and highlight it.

Daan,

Yes, this definitely looks like the direction I should go for most of
my form components.  Thanks for sharing it!

However, I also need to make a PasswordStrengthMeter, which will show
different values (and css styling) based on the strength of a password
entered into a password field.  Something like one of these:
http://ui-patterns.com/pattern/PasswordStrengthMeter

Before I embark on building it, do you have any suggestions on easy
ways to use your solution to do this?

Re: Runtime error with TabbedPanel and AbstractTab (I know it's my mistake somewhere)

[Daan van Etten]

Hi,

Maven should handle your dependencies. Have you added the wicket  
extensions dependency to your pom.xml?


Add this to the 'dependencies' tag of your pom.xml. The Wicket  
dependency should already be there.



org.apache.wicket
wicket-extensions
1.3.5


Change the 'version' according to which version of Wicket you use.

Eclipse should add Wicket extensions to your classpath when you have  
this dependency. (maybe with a mvn clean eclipse command)

and here's the corresponding runtime error:

This makes sense, as you can't directly instantiate an abstract

Re: Form Validations

[Daan van Etten]

Hi Ashish,

Do you use AJAX? Have you added the components to the  
AjaxRequestTarget with target.addComponent() ?


If you do use AJAX, you have to override both onError and onSubmit on  
the AjaxButton you use for submit. In both these methods you have to  
add the relevant components to the AjaxRequestTarget, or else they  
won't get updated.


Something like:

form.add(new AjaxButton("saveButton"){
protected void onSubmit(AjaxRequestTarget target, Form  
form) {

target.addComponent(sexFeedbackLabel);
target.addComponent(cityLabel);

// If you change other components, add them to the  
target as well.

}
@Override
 protected void onError(AjaxRequestTarget target, Form  
form) {

target.addComponent(sexFeedbackLabel);
target.addComponent(cityLabel);
}
});

It is possible that I guessed completely wrong about your problem :-)
If you like, I can update the demo project with a working AJAX sample.

By the way, the blog post and demo project is all based on Wicket  
1.3.4, so it is possible that this will not work for previous versions.

Daan

Sorry for the delay.  A shadow model basically grabs the actual

Then, when you're done with all of your edits you call "commit" on  
all of
your shadow models to write back into the originals.  So, I don't

you'll get a LazyInitializationException.  I guess it depends on

Re: Ajax validating individual form fields

[Daan van Etten]

Hi fatefree,

On 22 okt 2008, at 03:53, fatefree wrote:


Thank you very much, I didn't realize that the
AjaxFormComponentUpdatingBehavior submitted individual components, I  
guess i

got it confused with AjaxFormValidatingBehavior.

I think the only issue is when a form level validator needs to be  
used, for
instance to compare that two fields are equal. Am I correct in  
assuming
theres no way to attach a form component validator to a field and  
have it
compare against the value of another component? If so I'm not sure  
if it
would be possible to fire a form level validator on the onblur of  
the second

component without submitting the entire form.

I think you are correct.
Maybe it is an option to write a custom validator that compares the  
two fields, and attach that to the second field. The error can then be  
shown at the second field.


Another issue I thought of is if you use a password text field you  
wouldn't
be able to use AjaxFormComponentUpdatingBehavior because even if the  
input
is valid it would erase immediately. Maybe there is a clever way to  
override
the isPasswordReset so that it only is true when the form is submit  
through

a button and not that behavior?


I have no idea, but am curious to see your solution :-).

I think this achieves what you want.

Daan

On 21 okt 2008, at 15:28, fatefree wrote:



I have been trying to fulfill a requirement of a form, where each  
field is
validated one at a time after losing focus, and the entire form is  
validated
when a user clicks submit. I can see that there are pieces of what I  
want to

do thats possible, but I haven't been able to put them all together.

What I have tried is using the
AjaxFormValidatingBehavior.addToAllFormComponents(form, "onblur"),  
but as
you probably know this causes the entire form to be validated on the  
onblur
which is both confusing to a user who hasnt been able to put all  
values in,
and also seems to be excessive load as id rather the rest of the  
form be

ignored.

Then I looked into nested forms with the hope that I could add the  
same
behavior to a nested form, and then a user could submit a parent  
form which
would submit its child forms. While i thought this could be a  
solution, it

seems that when an inner form is submitted through the onblur behavior
above, the parent form is submitted and validated as well so I have  
the same
problem as I do in the first case. Keep in mind I have no button to  
submit

an individual field (so i cant call setdefaultformprocessing).

So finally I thought about making every field its own form without  
being
nested, in which case I know the validating behavior will work for  
every
form individually. The only problem (besides having a form for every  
input,
but thats manageable) is that I don't know how to use a button  
outside of
these forms, and force it to submit every form and proceed only if  
they are
all valid. I tried using an AjaxLink and calling process on every  
form i
have a reference to, but that seems to return true every time  
without any

validation.

Has anyone had a similar requirement or accomplished what I am  
trying to do?
I would be very appreciative of any example or ideas or direction i  
should

look into to accomplish this. Thanks in advance

Re: [OT] Process modelling (with Wicket front-end)

[Daan van Etten]

Hi Kaspar,

We use jBPM for our processes. We don't manage the processes from  
Wicket, as there is a nice plugin Eclipse for it.
jBPM uses Java and Hibernate, so you can create any GUI you like in  
Wicket and show underlying jBPM stuff (like tasks, processes, etcetera)


Regards,

Daan

On 9 okt 2008, at 18:03, Kaspar Fischer wrote:

Can anybody recommend a good process modelling tool that integrates  
with Wicket?


We would like to use such a tool for many activities in our  
organziation:


- We show processes to our end-users as part of our knowledge  
information centre
 website. So we need to present processes, interactively, if  
possible. The website
 (including the CMS front-end) runs on Wicket and ideally, we would  
like to

 edit the processes in a Wicket GUI, too.

- We are starting to provide e-learning solutions and there, too, it  
might be

 helpful to structure a course with a process modeller.

- We use processes internally for certain documents (in Alfresco CMS).

I have slightly touched jBPM as it is used in Alfresco CMS, and I  
have watched
the presentation 
given at . Also, I have read a  
little about
YAWL and heard of BPDM but as I lack experience with these tools/ 
models, I
wonder: What state-of-the-art tools (in Java) are out there, and has  
anybody

managed to get integration with Wicket?

Thanks,
Kaspar

Re: Non-modal ModalWindow ?

[Daan van Etten]

You could check the ModalWindow in wicket-extensions.

It contains a file called modal.js. In that file you can find the  
following function:


/**
 * Creates the mask accordingly to the settings.
 */
createMask: function() {
if (this.settings.mask == "transparent")
this.mask = new Wicket.Window.Mask(true);
else if (this.settings.mask == "semi-transparent")
this.mask = new Wicket.Window.Mask(false);

if (typeof(this.mask) != "undefined") {
this.mask.show();
}
},

You could change this function and the ModalWindow.MaskType so you can  
set a 'disabled' mask.
After that, you can create a JIRA issue with your code, so more people  
can profit from it :-)

Daan

Re: Wicket merchandise?

I really don't want to get into a 'design by committee' thing.
BTW: I've no idea about trademark or copyright issues.

I like to see a simple way for people to support Wicket or Apache,  
financially or by promoting it.
Some merchandize may help with both, at least a bit with the marketing  
(and sell the merchandize with no profit).


If you can use my designs with that, go ahead. If you want them  
modified or have better design idea's: go ahead.

Re: Wicket merchandise?

[Daan van Etten]

Here are some high-res versions:

http://stuq.nl/media/image/apache-wicket-tshirt-3,33x3,33-300dpi-transparant.png
http://stuq.nl/media/image/apache-wicket-tshirt-10x10-300dpi-transparant.png
http://stuq.nl/media/image/apache-wicket-tshirt-10x10-300dpi-white.png

Please try the 10x10 version first for the polo, because the aspect  
ratio is the same, but the resolution is much better.

Can you elaborate a bit on your first statement? You need a lot of
data-juggling for many clients, so I'd love to learn why it gives

What is this data juggling you talk of? If you use sticky sessions
(which is really necessary for any serious web application IMO) there
should not be any data juggling.
But if you need failover, you need a buddy system, because session  
sharing across multiple clusters is not that desirable or fast. You  
eliminate the necessary data-juggling by using an inferior way of  
failover. Because you need more memory and more processing power and  
LAN traffic to keep the state synchronized, you simply need more iron  
to serve your web application. So, you need to scale out to larger  
clusters earlier. It's cheaper and faster to keep the state at the  
client.




In my opinion it depends on your use case, but in high-load  
environments I'd

suggest to keep the state at the client.


As long as you have 1 page that uses the server as an RPC service,
this works. WHen you have to transfer state between different pages
you'd rather keep the state on the server. Imagine posting 1MB of
client side state to the server, and then sending it back (happened
with a .net app).
So don't use multiple pages. Make your applications without complete  
page refreshes. Replace parts of your functionality, like panel  
replacing in Wicket. When you've fetched that panel once, cache it at  
the client (if done right, browsers do this for you automatically).  
The server thus only gives data or (static) JS/HTML. Transfer client- 
fetched data in a format like JSON, which is easily compressed and can  
be fetched stateless. The server just 'dumbly' returns data, much like  
a session-less DB-server. It's even possible to aggressively cache  
these responses in the browser, on downstream servers and/or on the  
server.
This is exactly what GMail does, after your initial session. It seems  
to work for them... :-) GMail is one of the snappiest web apps out  
there. Google does complete page refreshes, but probably only because  
it is 90% search result data. Full page refreshes can also be cached,  
but only if they're stateless.





Sessions stored server-side not
only make it more expensive to scale out, but you're going to hit the
performance ceiling much sooner than with sessions at the client.


What performance ceiling are you talking about? There is no
performance penalty for storing state on the server, as long as you
don't have to synchronize it with other servers. Otherwise it is just
using memory, and functions as a good cache. To minimize clustering
overhead most folks choose sticky sessions with a buddy system for
failover.
As long as you don't have many visitors, you never will hit the  
performance ceiling. As soon as you need more than one server, you  
have to solve the session problem by limiting the synchronization of  
state or other workarounds. With a buddy system, you only have limited  
failover. It doesn't work with two independent data centers, unless  
you continuously want to push session state around. Really, with 1  
million users, and (guessing) 10.000-20.000 concurrent visitors, you  
really don't want to store all that session state. It will slow things  
down.

readup on some of the published whitepapers for high traffic sites

Try to have the server-side as stateless as possible. If the state  
is at the client, any server can handle the requests without  
exchanging state. See http://cwiki.apache.org/WICKET/stateless-pages.html 
 for a short intro. It will change the way you write your project,  
but keeping state server-side can be disastrous for real performance.


Yeah I know, problem are that our application are ajax heavy, and  
stateless and ajax does not cope well I've heard..


Maybe not within Wicket, I know too little of Wicket to draw a valid  
conclusion on that. But it is definitely possible.
Look for example at the SproutCore development model. They create  
their application in Javascript and do requests to the backend to get  
records, save records, etc. Their application runs in the browser,  
making the server more like a stateless backend (from what I  
understood of SproutCore).
I know it's possible (and done before) to build a Javascript  
application (or even desktop) that way.

We have looked at these things

 * Detachable models (not sure if it makes anything run faster, just
   that it keeps the memory footprint down making more users possible
   on each server)
 * Web Cache(Oscache, Ehcache or Apache http)
 * Internal cache(Eh distributed cache)
 * Clustering(simple web server clustering with apache
   http/loadbalancer/tomcat)
   o Would Jetty be better?

Are there something we have forgotten? Have other point to pick  
out? Should
we investigate terracotta also(seems they integration are working  
now)?

keeping state server-side can be disastrous for real performance.
