Re: [Wicket-user] initial Seam support in SVN

[Paolo Di Tommaso]

Really ?!  this is cool! but on which Seam version this integration is based
on ?

Thanks, Paolo

Hi all,

I just committed initial Seam support (I know, I know, I didn't the
see the light two weeks ago, but after Gavin King contacted me and
Igor came up with the brilliant idea of just starting with DI in mind,
I couldn't resist and had to see whether I could make it work.

I just committed the result of that as a wicket-stuff project
(wicket-seam-test). Please take a look and committers on wicket-stuff
don't hold back playing with it. I'd be interested to learn what
people think of it. I really have to get back to other things for a
bit now, so I don't intend to work on it much the next two months, but
I'd be happy to coop in the background.

It's a bit messy to get working now, mainly because I couldn't find a
decent maven 2 build for Seam yet. Which wouldn't be so bad weren't it
for the fact that it currently has about 1,500 dependencies, not all
clear on the versions either. :)

Anyway, here's part of the README I committed with the project. Hope
you'll have fun with it! Please send discussions on this to the
developer list instead of replying to this thread. I sent to the user
list to get better exposure.


Initial project for Wicket Seam support. Currently hosts the
integration code (which
due to Igor's and Al's great work on Spring and Guice isn't too much)
and a simple example
that nevertheless shows off that Seam can do scoped DI.

It's a start, and I can imagine that there are quite a few issues and
features that can be
worked on. Anyone interested in working on this project, please drop us a
line.

The plan is to keep it as Wicket stuff project for a while to play
around with, and if licensing
issues are resolved, Seams has a decent and recent maven deployment
and hopefully
a *much leaner* version (currently we'd need all the JSF, Hibernate
JEE dependencies
just to get it running) we can consider migrating this to a core
project. Otoh, it might
be a project with many interested people, in which case it'd actually
better stay here.

I think the most interesting features to look at first are related to
JPA/ Hibernate ORM and
validation support and transaction stuff. Next on my list would be
jBPM (might be nice
for wizard building) and possibly Seam's rule engine integration for
authorization. On the
longer term, we should keep an eye on WebBeans.

 Setting it up 

Currently, the only way to get this running is to check out this project
from

https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicket-seam-test
,
and
check out and build Seam from anoncvs.forge.jboss.com, repo
'/cvsroot/jboss', module 'jboss-seam'.
The Eclipse project files are set up for this and the wicket and
wicket-ioc project to be
all in your workspace and use each other as project dependencies. Only
extra thing you need to do
is to export most of the classpath entries of Seam. At the end of this
document, you can find the
contents of my Eclipse .classpath file for jboss-seam. Contributions
for other IDEs are welcome.
Hopefully Seam gets a proper maven 2 build soon and we can make this a
decent project.

Re: [Wicket-user] Seam2 and Wicket

[Paolo Di Tommaso]

I'm not absolutely specking about a core implementation.

This should regards a Seam or just JBPM integration. JBPM provides a very
nice process flow designer.

I think would be possible to have a process flow that defines the Wicket
page and the inner model binding-persistence.

Using the designer the user could draw visually the flow between pages ..
but this is what Seam do with page flow.

if you want something like that then you should really develop then on top
if wicket yourself.
because that won't make it into core.

Re: [Wicket-user] Seam2 and Wicket

[Paolo Di Tommaso]

I think it depends how Seam will be really decoupled from JSF.

I think it would be a nice option to Seam users to use Wicket as
presentation layer instead of JSF, but if so the integration should be a
Seam developers matter ..

What would be nice to have in Wicket from an integration with Seam is the
Pageflow mechanism.

I think this is one the most interesting Seam feature that is missing in the
Wicket framework.

I checked out seam from cvs today and browsed through the code a bit
(and also looked at JSR 299 for that matter).

Gavin states that Seam is now ready to be used in other frameworks.
Well... only if those other frameworks work with page flows, support
EL, manage state independenly from objects, etc. Stuff Wicket doesn't
need. But if that's all stripped, what's left? Really, it looks to me
that Seam (and JSR-299) are completely bound to JSF, if not
technically, than at least conceptually.

I think it is better to just stay focussed on what Wicket is good at.
We have excellent facilities for state management, model binding, etc,
and adding a framework in between will only make Wicket more heavy
weight. But please do speak up if you don't agree with what I think of
Seam + Wicket, and give some concrete examples of how such integration
would be an advantage.

Re: [Wicket-user] AjaxTabbedPanel and back button (Wicket 1.2.x)

[Paolo Di Tommaso]

Eelco .. I understand, and moreover in general versioning on ajax operation
is meaning less.

But in some cases like tab operation would be nice, because from the user
point of view changing tab switch is like changing the page content. So
would be useful to let interact with browser back and fwd navigation.

Looking on the Internet I found some interesting tricks [1] and [2].
Basically that make use of a hidden  iframe to store the history.

Perhaps a solution to handle versioning for a generic ajax action could be
very complex.

But a specific behaviour just to handle AjaxTabbedPanel versioning I think
it would not so difficult.

I will make some experiment and let you know.

FYI Paolo, we've been chatting about this before and had some ideas,
but it's a hard problem to solve. Unlike GWT (who does a good job
supporting the back button with Ajax), Wicket doesn't 'own' the
browser, so we'd have to use complicated workarounds, especially since
it has to be aligned with our normal page versioning. But biggest
problem right now that keeps us working on this is lack of time.

i dont think this is really possible in 1.2. Because ajax and versioning
is not really implemented
in 1.3 we have IPageVersionManager.rollbackPage() where you can rollback a
page version.
But to support or catch the backbutton in the browser you need to write
the javascript yourself that
then calls a behavior on the page that roll backs 1 and then set that as
the response page.

[Wicket-user] AjaxTabbedPanel and back button (Wicket 1.2.x)

[Paolo Di Tommaso]

Guys,

I have a page with an AjaxTabbedPanel component. When the user change the
tab selection and then click on the browser back button it come back to the
previous page.

I would like instead to come back to the previous selected tab (when has
been changed obviously).

This is the default behaviour with a TabbedPanel component. It is possible
to have the same behaviour with the AjaxTabbedPanel component?

Thank you,

[Wicket-user] Custom request listener (wicket 1.2.x)

[Paolo Di Tommaso]

I'm trying to create a custom request listener like the following code, but
something is wrong because I always get the "Page Expired" error page when
I'm invoking the custom listener (clicking on the link).

Any ideas to make it work?

Thank you, Paolo


On 3/16/07, Eelco Hillenius <[EMAIL PROTECTED]> wrote:


Here is a super-simple example of creating a custom request listener.

First, you create the new listener interface:

public interface IHelloListener extends IRequestListener
{
public static final RequestListenerInterface INTERFACE = new
RequestListenerInterface(
IHelloListener.class);

void onHello();
}

Note that it has a single method without parameters. This is a
requirement as you can read from IRequestListener's JavaDocs. The
other thing to note is the INTERFACE field; by instantiating a
RequestListenerInterface you register the interface, and the field
exposes a handle for constructing URLs using RequestCycle's UrlFor
methods.

Next, I simple patched the HelloWorld example like this:

public class HelloWorld extends WicketExamplePage implements
IHelloListener
{
public HelloWorld()
{
add(new Label("message", "Hello World!"));
WebMarkupContainer link = new WebMarkupContainer("link");
link.add(new SimpleAttributeModifier("href",
RequestCycle.get().urlFor(this,
IHelloListener.INTERFACE)));
add(link);
}

public void onHello()
{
RequestCycle.get().setRequestTarget(new IRequestTarget()
{
public void detach(RequestCycle requestCycle)
{
}

public void respond(RequestCycle requestCycle)
{
requestCycle.getResponse
().write("HELLO!");
}
});
}
}

The html is straightforward, with the link defined like: click me

And that's all there is to it: we created a new kind of listener for
requests.

Note that it is (still) bound to a page (or any arbitrary component).
It is entirely possible to decouple this further, from the top of my
head by providing a custom WebRequestCodingStrategy and override
doEncode for your specific purpose. But if you are doing that, you
probably might as well just create your own servlet.

It is certainly a design goal for Wicket to be very extensible.
However, it is *also* a goal to have different levels in our
abstraction. I agree with Igor that having services so upfront in the
architecture is or at least encourages scope creep, as it makes it too
obvious for users to start coding their own as if they were a
replacement for servlets and don't take the time to fully get into the
component mind set. As you can see from the example, there are pretty
much no limits to what you can do with Wicket, but we hope that doing
things like creating custom listeners are only used as a last resort.
And if you think you find a really good use, we'd appreciate it if you
would communicate it as there might be something we missed and can
result in a useful addition to Wicket.

My 2c, and again, if you have good and specific use cases, share them :)

Re: [Wicket-user] Custom request listener (wicket 1.2.x)

[Paolo Di Tommaso]

The quick start was in the included email, anyway here it is again ..

public interface IHelloListener extends IRequestListener
{
   public static final RequestListenerInterface INTERFACE = new
RequestListenerInterface(
   IHelloListener.class);

   void onHello();
}


public class HelloWorld extends WicketExamplePage implements IHelloListener
{
   public HelloWorld()
   {
   add(new Label("message", "Hello World!"));
   WebMarkupContainer link = new WebMarkupContainer("link");
   link.add(new SimpleAttributeModifier("href",
RequestCycle.get().urlFor(this,
IHelloListener.INTERFACE)));
   add(link);
   }

   public void onHello()
   {
   RequestCycle.get().setRequestTarget(new IRequestTarget()
   {
   public void detach(RequestCycle requestCycle)
   {
   }

   public void respond(RequestCycle requestCycle)
   {
   requestCycle.getResponse
().write("HELLO!");
   }
   });
   }
}

The problem seems that it cannot work if the implementing listener is the
page itself. But I've just discovered that it works fine using a component
insted of a the page.

Hi all,

Today, the newly-elected Board met for the first time. After we
got
done with our regular series of project reviews and other reports,
we
elected a new slate of executive officers. I'm happy to present
that
list:

 Jim Jagielski, Chairman
 Justin Erenkrantz, President
 J Aaron Farr, Treasurer
 Sam Ruby, Exec VP and Secretary

Welcome guys to your new offices!

We also established new three projects:

* Apache Quetzalcoatl: this springs mod_python and related bits
out of
the HTTPD project into its own TLP. Gregory Trubetskoy is its
Chair.

* Apache Wicket: this is a light webapp framework for Java,
graduating
from the Incubator into its own TLP. Martijn Dashorst is the new
Chair.

* Apache Commons: this is the venerable Apache Jakarta Commons,
now
spun out into its own TLP, with Torsten Curdt as its Chair.

Finally, we swapped a couple PMC Chairs:

* Will Glass-Hussin replaces Henning Schmiedehausen as the
Velocity Chair
* David Sean Taylor replaces Santiago Gala as the Portals Chair

That's it for this month. Please feel free to forward this to any
public/private forum as you see fit. If you have any questions,
then
please don't hesitate to ask myself or any other Director or
officer.

Cheers,
-g

We would like to congratulate all Wicket community members with this
remarkable feat, we couldn't have done this without you!

Furthermore, I like to thank the Board of the Apache Software
Foundation for the trust they invested in us. We will not disappoint!

We would like to thank Wicket's mentors:

* Alex Karasulu (whose birthday coincidentally is today… what a better
gift could you receive). Thanks for bringing us on board, and a Happy
Birthday!!!

* Upayavira, who made the transition even run smoother than thought
possible. Thanks for guiding us and I hope you'll stay for a long time
with our project!

* Bertrand Delacretaz, thank you for your help, votes and advise. We
will miss your involvement, but will certainly see you in the future!

* Sylvain Wallez, also big thanks for helping and guiding us. I hope
Wicket is still working within Joost

Finally, congratulations to the new officers, PMC Chairs and the other
two new projects: Apache Quetzalcoatl and Apache Commons! Welcome to
the club!

[Wicket-user] Convertes Hell (Wicket 1.2.x)

[Paolo Di Tommaso]

I need to replace the default Wicket Date conversion with a custom one to
override the default format for dates.

To do that I've made something like that in my wicket application :


 getApplicationSettings().setConverterFactory( new IConverterFactory() {
   public IConverter newConverter(Locale locale) {
   return new MyConverter() ;
   } }  );


Where:


public class MyConverter extends Converter {

   public MyConverter() {
   super();
   set(Date.class, new MyDateConverter());
   set(String.class, new MyStringConverter() );
   }

   public MyConverter(final Locale locale)
   {
   this();
   setLocale(locale);
   }

}

public class MyDateConverter extends AbstractConverter {

   protected Class getTargetType()
   {
   return Date.class;
   }

   public Object convert(final Object value, Locale locale)
   {
   return parse(MY_DATE_FORMAT, value);
   }
}

public class MyStringConverter extends AbstractConverter { 
 /*
  * ... that requires also an extra class MyDateToStringConverter ..
  */
}


This is really too complex to do a trivial job like a Date <---> String
conversion .

Exists a better and simpler way to override the default date-string
conversion ?

Thank you,

Paolo Di Tommaso

Re: [Wicket-user] Good Tutorial on core wicket

[Paolo Di Tommaso]

Anyway Francisco is right, I'm also thinking that Wicket is really missing a
good tutorial about core concepts.

I'm not new to Wicket, I'm using it for about a year, but there still a lot
aspects obscure to me like PageMap, page versioning, details of page request
cycle and so on.

Wicket is really a good framework that covers every details of the web
application stack (and they are many and many not just web page rendering
..), but I'm thinking that a good tutorial about Wicket core concepts would
be very useful to novice users as well as experts.


Thank you.

Re: [Wicket-user] Wicket manager resources inside Javascript and Css files

[Paolo Di Tommaso]

Guys, the problem is another, lets recap:

I've a folder with a javascript, a css and some images. From both the css
and the javascript I references these images using a relative path. For
example in the css url(the-image-1.gif) and in the javascript file image.src= '
the-image-2.gif'.

The css works fine instead the javascript image link is broke.

The problem is that a relative path in a CSS is relative to the location of
the css itself, so loading the css under the wicket
/resource/package.name.Class/ path it works fine.

BUT relative path in a javascript are relative to the page which loaded the
script NOT the script location, so the relative link will break!

Thanks, Paolo

Re: [Wicket-user] Wicket manager resources inside Javascript and Css files

[Paolo Di Tommaso]

This is very strange because I've all files (css, js, and images) all in the
same path.


From the CSS I'm referencing two images using the url(..) attribute with a

relative path. This works fine.


From the JS I'm referencing another image in the same path of the

javascript, so using a:

image.src = 'relative-image.jpg'


But in this case the image is broke, looking at the server log I can see
that the image path is not translated under the wicket 'resource/...' path.

Both the css and js are added in the same way ..

add( new StyleSheetReference("sortable_css", new ResourceReference(
WorkflowListPage.class,"sortable/sortabletable.css")));

add( new JavaScriptReference("sortable_js", new ResourceReference(
WorkflowListPage.class,"sortable/sortabletable.js")));



Thanks, Paolo

Be *very* careful using getClass() there. Are you sure the actual
class isn't a subclass of the class you really want? Try to use
MyClass.class in resource references.

> Is not translating the path for relative resources ..

If your javascript file is served from /resources/... then everything
that is declared relatively should go through that as weell.

Really ?! .. but in which version has been implemented.

I'm using Wicket 1.2.3 and adding a javascript using the following code:

add( new JavaScriptReference("sortable_js", new
ResourceReference(getClass(),"sortable/sortabletable.js")))

Is not translating the path for relative resources ..

Also by relatively addressing those images. There are quite a few
components that do this (for instance wicket-datetime's DatePicker
component).

Re: [Wicket-user] Wicket manager resources inside Javascript and Css files

[Paolo Di Tommaso]

Yes, for example in a JavaScript could be common to have something like
that:

document.getElementById('a-image-element').src =
'/path-to-image/resource.gif';

Anyway I've solved using in the JavaScript a CSS class, so reconducing the
the previous case.

Thanks Paolo

[Wicket-user] Wicket manager resources inside Javascript and Css files

[Paolo Di Tommaso]

Dear all,

which is the best strategy to use Wicket manager resource path from inside
Javascript file and Css?

For example I need to replace and url() attribute inside a css with a gif
deployed with the wicket application ..

Is there any example ?

Thanks in advance,
Paolo

Let's say that the  have the following hierarchy:

Page A

Page C



The page A will be:



Some stuff here 







The page C




Some details





But how to write the Page B markup ??

Re: [Wicket-user] Tapestry -> Wicket | Action Service

[Paolo Di Tommaso]

It could be useful in situation where UI components are not mapped to Wicket
components, but you wants access to page state.

For example just think about a javascript input dialog. How to send the user
input value in a wicket page?

Or in any other situation where you use third parts UI widgets not supported
by Wicket, but you want to interact with the server side page status.

wicket is about the UI, if you need callbacks that have nothing to do with
UI like youve mentioned why use wicket for that?

wicket focuses on doing one thing but doing it very well. we do not
provide a generic request/response framework because that is what servlets
do.

Re: [Wicket-user] Tapestry -> Wicket | Action Service

[Paolo Di Tommaso]

Robert, I agree with you definitefly.

Wicket should provide a "generic" PageService not tied to a specific
component. It would be very useful for client-server interaction where a
visual component is not req

Hi!

A Tapestry service basically has a

Something like a PageService would do something like
cycle.activate(cycleparam[0])

Now I understand that I don't usually need a PageService. The onClick for
Link components are much easier to use. However what if I don't have a
component and
there is some javascript that wants to change the page? I'll try to write
about this more in the other replies in this thread.

[Wicket-user] AutoCompleteTextField issue (wicket 1.2.3)

[Paolo Di Tommaso]

The AutoCompleteTextField does not invoke the functions registered by
Wicket.Ajax.registerPostCallHandler() after the ajax request has been
completed.

Is someone else experiencing the same problem?


Thank you, Paolo

Re: [Wicket-user] [Upload] Upload and Ajax

[Paolo Di Tommaso]

I have implemented an ajax upload using wicket, but you still have to use
the common trick to submit to an hidden . For example:






Submitting to an hidden frame you will need to prevent wicket to send a
response using the following code in the Form#onSubmit()

// avoid redirection
// Tell Wicket we're going to do the redirect ourselves.
getRequestCycle().setRedirect(false);
// Make sure no output for the current cycle is ever sent.
getRequestCycle().setRequestTarget(EmptyRequestTarget.getInstance());


Sorry if the first time I gave an incomplete response to the problem.

Re: [Wicket-user] [Upload] Upload and Ajax

[Paolo Di Tommaso]

You have to force Wicket to avoid reloading the page after the file has been
uploaded. I've used the following code in the Form#onSubmit() method:


   // avoid redirection
   // Tell Wicket we're going to do the redirect ourselves.
   getRequestCycle().setRedirect(false);
   // Make sure no output for the current cycle is ever sent.
   getRequestCycle().setRequestTarget(
EmptyRequestTarget.getInstance());

Re: [Wicket-user] DatePicker and ModalWindow

[Paolo Di Tommaso]

Anyway I've found another problem with a DatePicker on a ModalWindow:

If you open a DatePicker and then close the ModalWindow, the DatePicker does
not disappear and remains open.

I know that a stupid case but at the same time is a really user annoying
behaviour.

Anyone experienced that?

Re: [Wicket-user] Custom web form in Wicket

Me and Fillippo are working on BeanPanels project on Wicket-Stuff.

The idea, nothing new but just a shortcut in some situation, is to render a
form/panel dynamically based on the bean properties content.

The code is available, but I cannot guarantee on api breaks because we are
really in a early release phase.

Not with an anonymous access, but I should also have commit access
since I'm listed as 'developer' in wicket-stuff

Yes!
I've just done a quick check and the latest wicket-stuff revision with
this project is the 639... (unfortunataly I'm not able to check it
out... maybe some issues with my platform)

Anyway, if you have the sourcecode of 1.1.1 it will be enough to start.

Good question.

I've found the BeanFormPanel source in a old 1.1.1 wicket-extensions
release.

If the project bean-edit is missing I could start it again together with
Filippo.

That's sound interesting. Is that old code still available somewhere?

If you agree we could create a new wicket-stuff project starting from it.

Re: [Wicket-user] Directly map a bean to HTML form

[Paolo Di Tommaso]

Stefan, you are absolutely right.

I agree with you that to achive a "production" result you need to write a
detailed html.

But a "BeanPanel" would be very useful in the first project iterations or to
make an application prototype.

This could improve a lot a project startup time.

Quite interesting.

Although Wicket use a different approach that requires explicitly to map
html fields to java objects - and this is what makes it so great - there
are
situation where would be very useful to have a component like that (for
example for fast application prototyping ..).


Moreover it would be quite easy to implement extending a panel and using a

[Wicket-user] Link#setEnabled( false ) does not disable button element

[Paolo Di Tommaso]

Invoking the Link#setEnabled( false ) on a  element
will not disable the component.

The onclick handler will not be invoked (disabled) but it does not apper as
a disabled component.

Instead invoking Button#setEnabled( false ) will render the button disabled.



I think it would be simpler if it will be rendered disabled in both cases.
Won't be?

[Wicket-user] - Page redirect infinite loop

[Paolo Di Tommaso]

Guys, I'm experiencing a very strange problem using Wicket (1.2.x) that I was unable to fix until now. I have mounted some pages overriding WebApplication#init() method like this: 
public void init() {  mount( "/test", new QueryStringUrlCodingStrategy("/test", MyPage.class) );
}So I can references the page by an url like "
http://host.com/web-path/servlet-path/test".But // SOMETIMES // invoking that page an infinite redirect loop occurs and the only way to stop the page loading is to press the browser stop button. I'm unable to replicate the problem because it happens in some aleatory way. But I've noticed two things: 
* wicket append to the URL the following parameter "wicket:pageMapName=wicket-0
" like that:http://localhost:9080/coin-budget/budget/print?request_id=1521&wicket:pageMapName=wicket-0
 
* moreover after the first time it happens it will persist for every subsequent request to that page unless I don't close the browser and start it again ...It's a very nasty problem, any idea to fix? 
Thank for helping.- Paolo

[Wicket-user] Custom number formatting

[Paolo Di Tommaso]

I need to implement a special numbers formatting in my wicket application. Basically I have to round number to the first digit and use a blank space as thousand separator. For example instead to display number like '1,
000.33' it is required to display (and user will input) '1 000'.I can do that in Wicket? Thank for helping.-- Paolo

Re: [Wicket-user] Problem response page using AjaxFormSubmitBehavior

[Paolo Di Tommaso]

Igor you right when you say that generally is a contradiction having a page redirection on a ajax request but in the case of AjaxFormSubmitBehavior the request is to submit data, and common semantic for submit is "save data and proceed with next page in the flow".
Anyway I want to be more detailed about my use case: I have a complex form with a lot of fields with cross validation rules (some fields validation depends from other fields value). It's very common that users make a mistake filling out the form so I would avoid to have complete page render each time the user try to submit data. Only If there are no error on page I will go to the next page in the application flow.
So  AjaxFormSubmitBehavior is perfect for this use case. In onSubmit(target) method I check for any validation error, if any exists I will notify user about that with a _javascript_ alert  / 
target.addJavascript("alert('..')") /.If validation pass the form onSubmit will execute storing submitted data and proceeding to to next page / 
setResponsePage / .  I was a bit surprised to see that setResponsePage
 was not working in conjunction an AjaxFormSubmitBehavior  request. I think Eelco proposal to make AjaxRequestTarget translating page redirect to 
window.location is good idea. In this way setResponsePage semantic will be more uniform with both plain and ajax submit.Thanks. - Paolo But in my case, I'm using  
AjaxFormSubmitBehavior 
to validate and saving user data . On 7/21/06, Eelco Hillenius <

[Wicket-user] Problem response page using AjaxFormSubmitBehavior

[Paolo Di Tommaso]

I'm getting a bit confused how to redirect to a new page after a form submission using AjaxFormSubmitBehavior.I use the onSubmit method of 
AjaxFormSubmitBehavior component to notify user for special message, for example: 
buttonSave.add( new AjaxFormSubmitBehavior ( form, "onclick" ) {     protected void onSubmit(AjaxRequestTarget target) {
    if( !getFeedbackMessages().isEmpty() ) { 
        target.addJavascript( "alert('Validation failed')" );    }
    }});and the form 
onSubmit to save data and redirect to the next page:form = new Form("form1") {
  void onSubmit() { 
    if( findSubmittingButton() == buttonSave ) { 
  dao.save( object );  setResponsePage( NextPage.class );
    }   } 
};The problem is that in this way I will get the response page as response content of the Ajax call!How to redirect to another page using AjaxFormSubmitBehavior?

Re: [Wicket-user] Changing visibility via ajax

[Paolo Di Tommaso]

You are right, but the problem is the panel that is not really a panel as I say but a container .. so I cannot switch with an empty panel. Anyway I don't think is a bad idea to have a display attribute for Component, for now I've solved using the following class. 
public class HideableContainer extends WebMarkupContainer {
    private boolean display;    
    public HideableContainer(String id) {        this(id,null);
    }    
    public HideableContainer(String id, IModel model) {        super(id, model);
        add( new AttributeModifier("style", true, new AbstractReadOnlyModel() {
            public Object getObject(Component component) {
                return display ? "" : "display: none";            } 
                    } ) );
    }    public boolean getDisplay() {
        return display;
    }    public void setDisplay(boolean display) {
        this.display = display;    }
    }Thanks.- PaoloOn 7/21/06,

If so, I should add an WicketAjaxIndicatorAppender instance to every components for each I want an Ajax notification message. Is it possible to add AjaxIndicatorAppend to page and get notifications for every ajax call on that page?

[Wicket-user] Master-details form

[Paolo Di Tommaso]

I'm using wicket to developer a budget application. I've a classic Master-Details data entry form and relative POJOs. For example
public class Order {     private Long id;
    private Data date;    private Float amout;
    private Float tax;    private List  items;
} public class OrderItem { 
    private Long id;
    private String description;    private Integer qty;
    private Float unitPrice;}Customer is requesting to handle all order data entry using only one form.
How to handle that using Wicket? For example suppose I want to edit an existing order: which is the best approch to display data-entry fields for each OrderItem 
element in 'items' collection?Thank you for helping.Paolo

Yes. It's really very strange. I don't use any filter, I've tried also to force a filter like "**/*.java, **/*.html"  ... but it still refuse to copy any html file. The only way to make it to work is switching to a fresh workspace.

[Wicket-user] Eclipse don't copy .html to output folder

[Paolo Di Tommaso]

As default Wicket requires .html files to be in the same path where .class files are.Using Eclipse I have the problem that it misses to copy .html file to my class output folder. It is very strange because it copies all file extensions from source folder to classes folder (*.properties, *.txt, *.htm) except *.html (Murphy law maybe)! 
Anyone else encountered this annoying problem developing Wicket application with Eclipse?Thank you for helping, -- Paolo

Re: [Wicket-user] RadioGroup onchange event (Wicket 1.2)

[Paolo Di Tommaso]

Using setRenderBodyOnly(false) on RadioGroup it is possible to add a AjaxFormComponentUpdatingBehavior
to  the group itself.The problem, as with RadioChoice, is that it will not update the checked radio.I've posted a possible solution here:

Re: [Wicket-user] Is AjaxFormComponentUpdatingBehavior working with RadioChoice component?

[Paolo Di Tommaso]

Making some investigation I found that the problem is on call to _javascript_ function "wicketSerialize(this)" on onchange event attached to the radio  . The problem arise because "this" refers to  element but wicketSerialize don't know how to handle the inner radio input fields. 
// returns url/post-body fragment representing element (e) 
function wicketSerialize(e) {    var tag = e.tagName.toLowerCase();
    if (tag == "select") {    return wicketSerializeSelect(e);
    } else {
    if (tag == "input" || tag == "textarea") {    return wicketSerializeInput(e);
    }    }
    return "";
