org.apache.wicket.WicketRuntimeException: Unable to write the response
Hello, I have just noticed that the various components I have that render the same underlying data, when the exception occurs, then they all have a different instance of the underlying data. I have used: add(new CompnentX(getSession().getMyData())) so they were all constructed with the same data from the session object (final reference). However, after the exception occurs, different components have different underlying data. I have a workaround, before rendering I have to call things replace(new CompnentX(getSession().getMyData())), this is a workaround. Not sure what's happening and why I have to sprinkle the code with replace or for listviews setList before rendering is suffiicient.

Memory leak using UndoPageVersionManager
Hi all, i'm trying to investigate a memory leak. I have taken an heap memory snapshot from the production and actually i know which wicket page retains a lot of memory without releasing it. It's a simple org.apache.wicket.markup.html.WebPage containing a org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable updated every 2-3 seconds via ajax calls. The page uses a UndoPageVersionManager, even if it doesn't need it (the user cannot hit back button in browser) which in turn contains a ChangeList. My analisys suggests that not all the ChangeList are released by garbage collector. I have verified that my code never hits the method UndoPageVersionManager.componentRemoved (so, any delete operation of objects inside the ChangeList collection is never called). Unfortunatly, i cannot reproduce the problem in my local environment. My hope is that adding 'setVersioned(false);' in my Page the problem should be fixed, but i'm not sure. What do you think about?

Re: Wicket, FOP, Markup Inheritance and Markup Type
Adrian, is not a strange question, I've implemented it and works very well.
And in some use cases is a perfect choice.
In my implementation I use a FopPage that declares page#getmarkuptype() {
return fop}
The nice thing is that all panel added in that page will look for an
associated markup will a suffix .fop (instead of .html).
This means that you can have a panel implementing a common business logic
with two skins, one html and one fop.
When used in html page it will use the HTML panel and when added in the FOP
page will produce the FOP markup.

Hello everybody
A quick question out of curiosity. Has anybody played around or tried to
generate XSL-FO from within your Wicket project?
What I mean is this:
- Add an XML file to every HTML file.
- Tell Wicket to use the XML instead of the HTML file for the markup.
- Have Wicket do the markup inheritance magic and rendering of a FO file
(instead of plain HTML).
- Use the resulting FO to render PDF with Apache FOP.
- Present the PDF file instead the HTML to the client.
Anyone did so? Anyone played with Wicket and did so in a Swing application
(instead the web environment)?
I know, these questions may sound strange, but I am currently thinking
about the possibilities of Wicket's markup inheritance and if it is
possible (and makes sense) to use Wicket as a reports generator. Not what
it is intended to do, but just pretend everything makes sense. :)
Thanks for your comments.

Re: Wicket and Ext JS integration
I could be interested to share experience about that, but now I'm really in early stage so I think it would be too early to share the code. Anyway the main idea is to use the Wicket behaviour feature to attach an Ext component to the associated Wicket component. This is the easiest part. More complex integration like Data Store could be always done using a Wicket ajax behavior. But I' haven't yet tryed to integrate more complex stuff like editable grids, groups and so on . .

Best to strategy to have a Wicket page returns a binary content by default
Guys, I'm using Wicket to create pdf content using Apache FOP. The idea is to have a FopPage that extends the root wicket Page component and declares fo as marketType. The FopPage parses FOP markup instead HTML markup. I'm able to manage the fop to pdf binary conversion using a custom PdfRequestTarget, but it requires to specify it explicitly, invoking RequestCycle.get().setRequestTarget(new PdfRequestTarget(this)); every time. So the question: is there a way to make a custom RequestTarget the default to certain pages? Or exists a better strategy to override the default render strategy to return a content different from HTML ? Thank you, -- Paolo

Wicket integration in Seam 2.1
Guys, A very interesting interview to Pete Muir about the upcoming JBoss Seam 2.1, especially regarding Wicket integration as presentation layer. [..] Firstly, we want to support Wicket, as a first class view layer. Well, what does this actually mean, with some sort of technical details. Well, what we want to be able to do is allow you, obviously, to be able to access your Seam components for a Wicket club, using annotation controlled injection, to be able to control conversations, with annotations from inside your Wicket class, to be able to control your business process management tasks and your business process management processes themselves. So basically, all the orchestration stuff that you need to do with writing the view side of your app. [..] http://java.dzone.com/articles/whats-new-seam-21-an-interview Enjoy. -- Paolo
Re: Issue with the FileUploadField
The trick is based on a hidden iframe, like the following:
iframe id=upload_target wicket:id=upload_target name=upload_target
style=width:0px;height:0px;border:0 /iframe
form wicket:id=form0 target=upload_target
div id=upload-field-handler style=position: absolute; z-index: 100;
display: none
input id=upload_field wicket:id=upload_field type=file
class=DisplayText size=55 onchange=upload(this) /
/div
/form
And tell wicket to do not redirect on form upload when the submit is
terminated:
public void onSubmit() {
getRequestCycle().setRedirect(false);
getRequestCycle().setRequestTarget(EmptyRequestTarget.getInstance());
}
I'm attaching my code so you can check details.
Have fun

Hello All,
I have an issue with the file upload
I have a Fileupload input filed on a tabbed panel. The first time when I
select a file and submit, the following returns null
FileUpload upload = fileUploadField.getFileUpload(); return null.
But if I select the same file again and submit I get the value. Have anyone
encountered this before ?
If this can be of any help, the TabbedPanel link is a AJAXSubmit as I need
to retain some of the form values on tab change .
Also the above action occurs on the submit of another File Upload button
on the form and not on the Tabbed link Submit
Also is there a AJAX Fileupload component anyone know of or has written? .
Thank you all in advance

}
public abstract class ExtAbstractBehavior extends AbstractBehavior {
/**
* Used to add all common Extjs required JavaScript and CSS
resources

@Override
public void bind(Component component) {
if( component == null ) throw new
IllegalArgumentException(Argument
cannot be null);
component.setOutputMarkupId(true);
component.add(HeaderContributor.forCss( Extjs.Css.EXT_ALL ));
component.add(HeaderContributor.forJavaScript( Extjs.Js.EXT_BASE
));
component.add(HeaderContributor.forJavaScript(
Extjs.Js.EXT_ALL_DEBUG ));
}
abstract String getExtjsClassName();
abstract String getOptions();
@Override
public void onRendered( Component component ) {
/* create a copy of options */
Config options = new Config( config );
/* initialization */
config(component,options);
/* get the string version */
String sConfig = Extjs.serialize(options);
String extjs = new + getExtjsClassName() + ( + getOptions()
+
);;
//TODO log here
Response r = component.getResponse();
r.write( JavascriptUtils.SCRIPT_OPEN_TAG );
r.write( extjs );
r.write( JavascriptUtils.SCRIPT_CLOSE_TAG );
}
}
That's all!
Obviously this is just a simple test but it works and can be extended
easily
for other widgets.
What I've found not trivial is to pass/define the Extjs widget
property/configuration in a easy/elegant way.
Would be interesting discuss this...

A custom tag library is under development that accesses the repository and allows url mapping. It should certainly be possible to develop a frontend in Wicket; the models that we use to access the repository are easily reused. To embed plugins, e.g. those used by the CMS, does require some support from the environment. The Wicket session needs to provide a valid JCR session, for example. And if JSP will be delivering, can we build CMS-agnostic wicket components that could wor as they would in a normal wicket app (wrapped by some plugin adapter of course)? yes, if you're components don't need to have any interaction with the CMS then this is certainly possible. When you do want to have an interaction, some additional constaints will (likely) be present due to the possible actions of other plugins.

Re: Seam Wicket integration and conversation scope
Nice and interesting. This could be a valid alternative to simulate the Seam
conversation-scoped persistent context.
Although doing so the presentation layer is too tied to persistent session
handling aspect. I think this could be really useful in a simple scenario
with few pages, but in complex use causes (and integrating other frameworks
like jbpm that need to share the same hibernate session) it will drive in a
hell.
Thank you.

As far as I can tell Seam uses the conversation scope as a step between
request scope and session scope to persist values across a couple of
requests, for instance a user creation wizard, etc.
I don't know what integration they've enabled or how it works, but
passing
an object between requests is simple and straight forward in wicket.
Say
that you want to pass a user object (or any other combination of
objects)
from one page to another when the user clicks a link:
public class SimplePage extends WebPage
{
public SimplePage(final User user)
{
add(new Link(link)
{
public void onClick()
{
setResponsePage(new SomeOtherPage(user));
}
}
}
}
You would pass it directly by reference. Like I said, I don't know how
Seam
is integrating, but when you're using Wicket you don't really have a
need
for something like a conversation scope. You can use whatever
granularity
you'd like to pass objects between pages, not necessarily bound to any
particular scope.
Please let me know if I'm just completely missing your point here.

Seam Wicket integration and conversation scope
I'm playing with the latest Seam release (2.1.0.A1) containing a really interesting integration of Apache Wicket. The current implementation appear to be really promising and I hope it will improved in next release. One of the most interesting feature already implemented is the conversation scope that enables conversation-scoped persistent context. I've noticed that the conversation between different wicket pages is maintained only navigating by a form submit action BUT it doesn't when moving between pages using other components i.e. Link, AjaxLink, Button, AjaxBehavior .. and so on. This makes it useless, in particular with Ajax interactions where it is expected to have the maximum benefits (no more LazyInitializationException .. ). Is this a know issue? It is planned in next release to maintained the conversation between Wicket pages navigating by Link and AjaxBehavior also? Thank you, // Paolo

Guys, Which the best pattern using wicket to write validation rule that span over more than one field?! Take in consideration the following use case: There is a form with two field Field-A and Field-B. Field-A is mandatory and contains a date value.

Re: the flow of wicket
I disagree with this answer. The fact that request handling stuff is not a public api, is A GOOD REASON because it should be documented better, not viceversa. And I really don't understand in which way this could prevent you to change - eventually - in future wicket versions. I not a newbie user and I'm really a Wicket enthusiastic user and pleased to be involved in its great community, but I have to admit that some topics are still obscure. The request flow handling is one of the most important topic to know in a web application framework, being so I think it would be very interesting to have only a brief description, for example a sequence diagram showing the components interaction starting from the WicketFilter (and/or the WicketServlet) involved in a web request handling. Hiding this stuff or, even worse, asking the users to debug the framework to understand what it should important to know I don't think is a good approach because it is precisely this that leads to wrong assumptions, that could break in future.

Re: [Wicket 1.2.6] How to get Wizard's form from inside a WizardStep?
Let me guess .. you need the form to create a AjaxSubmitLink instance. But the #findParent(Form.class) will return null until the component hierarchy is constructed, being so you cannot invoke it at component construction-time. A possible workaround is to postpone the findParent(Form.class) method invocation instantiating a the AjaxSubmitLink using a form proxy. I've hacked this writing a custom AjaxFormSubmitBehavior that does not require the form instance on its constructor but just discover it - invoking #findParent(Form.class) method - when is required. Me fate sempre lavora.. ;) P On Jan 4, 2008 12:43 PM, Fabio Fioretti [EMAIL PROTECTED] wrote: First of all, many compliments for the great Wicket 1.3 release: we're looking forward to port our application to the new cool version!

What leaves me clueless is the fact that WizardStep instances are added to the WizardModel instead of the Wizard, so doing something like this from inside the WizardStep: Form form = (Form)WizardStep.this.findParent(Form.class); seems to return null; moreover, this makes me wonder how the same instruction inside WizardStep.AddFormValidatorAction.execute() can succeed.

This need becomes more obvious when you consider that (except repeaters) there is a 1:1 correspondence between HTML elements with wicket:id and Wicket components, and it wouldn't be nice to need to change the HTML files runtime :) One consequence is that all components of the page always get constructed even if they are not visible, so on one hand you don't want to do heavy work in the constructor of such component but on other hand you get more fail-fast with regard to component creation.

Re: Weird Ajax non-English characters encoding problem.
I'm experiencing a similar problem i.e. I'm able to submit any Latin
encoded characters but when I'm using an AjaxSubmitButton some characters
are not encoded properly. This happens also specifying the right encoding
with:
getRequestCycleSettings().setResponseRequestEncoding(ISO-8859-1);
So it appears to be clear that is an ajax encoding problem with wicket.
Looking at the Wicket ajax code I found the following fragment:
if (t != null) {
t.open(POST, url, this.async);
t.onreadystatechange = this.stateChangeCallback.bind(this);
t.setRequestHeader(Content-Type,
application/x-www-form-urlencoded);
t.setRequestHeader(Wicket-Ajax, true);
t.send(body);
return true;
} else {
this.failure();
return false;
}
Now, how is defined the content encoding of an ajax request? I was expecting
something like charset=defined encoding in the ajax request request
header.
Otherwise how the IRequestCycleSettings#setResponseRequestEncoding() will
affect the charset definition in the ajax call?
Thanks,
Paolo

Hi Matej and Johan,
thanks for your replies.
I'm using Latin1 because the page I'm talking about is part of a
legacy web application fully encoded in ISO-8859-1. The application
server it runs on is Tomcat 5.5, which defaults to Latin1, so it
shouldn't be a problem.
I tried to set the request/response encoding in the application main
class using:
getRequestCycleSettings().setResponseRequestEncoding(ISO-8859-1);
but nothing changed, except that Wicket Ajax Debug now prints:
INFO:

Hi all,
thanks in advance for your time and suggestions.
I'm building a really simple page made up of a form with a text area
and a submit button (instance of Button). An AjaxFormSubmitBehavior
that performs the save operation is added to the button. The page
is
encoded as follows:
meta http-equiv=Content-Type content=text/html;
charset=ISO-8859-1
Everything works fine until a user submits a non-English text
(French
or Spanish, with characters like íéñ, still supported by the
ISO-8859-1 encoding): all non-English characters are scrambled.
What appears weird to me is that the problem doesn't happen if I
use,
for example, a SubmitLink instead of an Ajax-enabled Button.
This makes me point to Ajax as the responsible, and to the fact that
Wicket uses UTF-8 for requests... but I really have no clue about
how
to fix it.
Any idea?
