Martin,

Wicket will take care of the nasty details for you:-) Take a look at
[1] or search the list for different solutions.

Override getAjaxCallDecorator() and return an IAjaxCallDecorator which returns 
"getElementById('"+yourButton.getId()+"').disabled = true;"+script for 
decorateScript(). You also need to enable it in the success/failure methods.

Use a veil to block the page while AJAX is executing?

Preventing double-clicking of Ajax-Buttons

[MattyDE]

Hi,

any ideas how i could disable (client-side) an ajax-button after clicking
them once?

How should i process Form-Validation too? If the validation fails, the
button have to be enabled again to change some values, and re-submit the
form afterwards.

Any hints?

Thanks :)

Re: Java in CMS arena,..wicket to lead the way?!

[Arjun Dhar]

@Richard

"Apache Roller is a Java based blogging system, if you're looking for
something. "
--- I've used Roller and like it a lot functionally. But am circumspect of
its integration capabilities with other CMS, and also integration of its
Admin module to be a plugin-component into another CMS instead of a stand
alone system. Their Wiki isnt that insightful to tell me all this. So beyond
functionally what it does stand alone I'd like to understand its integration
capabilities more. If you guys know and are doing something in Lenya for
that, please share it. I'd love to understand first..and then possibly
contribute about things I've mentioned.

I think the basic point it to allow *integration*, scripting, plug-in 
capabilities and not have to provide everything under one roof. I like BRIX
for this reason; simple CORE and extend anywhere.. but it suffers from other
things I've mentioned above. Will give Leya a shot too.

thanks a lot.

@Brian - 

"but there's a lot of fragmented development and not a lot of investment
going back in." 
--- yes, this is what I sense. I'm not even aware of the Brix community
unlike Wicket which is more active. If you see the Brix architecture page i
put some comments but Looks pretty dead which is pretty de-motivating.

"I would challenge you to create needs in the core by demonstrating those
needs" 
--- No, I dont think the core needs to be changed as such, Simple is better
& should remain preserved. However we can upgrade the Wicket dependencies
from time to time? :) ?!
I ALSO like the idea it does NOT have a custom workflow etc built into core,
coz I'm a fan of Drools work flow & Rules Engines to allocate business logic
and workflows; Apache Camel & Spring Integration.

"If you are worried about people having access to your assets"
--- No sir, the more the merrier. I'd love to get into it once i'm sure to
commit time & effort.

>From a "using for commercial web sites" perspective, issue is from a UI
perspective the Admin module has a poor finish compared to Alfresco and say
Hippo; its not just the CSS but the general layout sucks. ...I cant sell a

I can look to contribute on.

Complicated master-detail form

[devnullable]

Hi!

I am evaluating different Java frameworks for complete rewriting of old
jsp-based web extranet system and now checking Wicket. I have studied Wicket
before but now one major obstacle is slowing me down.

I need to implement many master-detail forms like order-order lines. Screen
would have order related fields on top, below that a grid of order lines and
bottommost fields of order line. Selecting a row from grid should update
values of the currently selected line to fields.

I found an article
http://wicketinaction.com/2008/10/building-a-listeditor-form-component/ but
that is not similar to my case because it's showing all lines, not just one
selected.

So how should I advance? Is my example doable only with Wicket or should I
use for example jQuery also? Any advice much appreciated!

Add the entire form to the AjaxRequestTarget.  The form's action URL is
out-of-date and pulls up the old version of the page.

Tons of possibilities, but obviously you'll be using Forms, DropDownChoice

You're over-complicating things.  He meant just write a regular ol' servlet.
 Servlets already respond to HTTP requests - there's no daemon junk to worry
about.  Write a servlet, put it in your web.xml and make your upload form
submit to it instead of Wicket.

Thanks mate, I will investigate more on this, but can you elaborate it a
little bit? 

I can think of the following

1. When the application starts up, the servlet will be loaded up.
2. In its init(), I would have to create a process that is more like a
daemon and waits for it to be requested or invoked.
3. From the GUI, actor uploads a file - this has to delegate the request to
the servlet.Which then does the job

Am i on the right track?

Looking for inspiration/suggestions

[Emmanouil Batsis (Manos)]

Consider the task of building a wicket-based UI that allows users to map 
properties between entities (e.g. a mapping between InventoryAsset to 
SupportTicket properties), how would you do it? Some considerations are 
datatype mappings but that may or may not be relevant to the wicket 
layer. The UI will probably produce an XML file as a serialization of 
the mapping between the two entities.


I'm new to wicket and just looking on suggestions on components to use 
etc. Wouldn't say no to any time saver :-)

[announce] wicketstuff-core 1.4.12 released

[Michael O'Cleirigh]

Hello,

I've cut a matching release for wicket 1.4.12 that has just shown up in 
the maven central repositories.


The stable branch for 1.4.12.1-SNAPSHOT is located here: 
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/branches/wicketstuff-core-1.4.12 



I will plan on releasing the 1.4.12.1 point release within one Month 
from today.  If you commit code and want a release sooner let me know as 
one month is the worst case target.


And the release tag: 
https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/tags/wicketstuff-core-1.4.12


The artifacts have been promoted and are available through maven central 
like this:



org.wicketstuff
jasperreports
1.4.12


Regards,

Mike

This is all JS.  If you need to get it passed into Wicket, you'll need to
grab it with JS and then add it as a query parameter (or similar) to a
Wicket AJAX request.

Re: Mouse click position

Yes, I agree it is more of javascript. But in my code I am trying to use only
java scripts bundled in wicket. Did not want to add more java script
libraries to keep it simple. I use attribute modifier for all dynamic
behaviour's, similarly I am trying to open a window popup but instead of
positioning in middle, would like to position just next to the mouse click.

Any clue to get the mouse click position will be great.

This is just JavaScript - not really Wicket-specific.  There are a lot of JS

It might help to look at the hierarchy for AjaxRequestTarget.  Notice

Ajax "Target"

[Chris Colman]

I'm just wondering what the 'target' is in the term Ajax target. From my
desktop days I was lead to think that 'target' meant a specific
component but I'm not sure if that's what is intended in the Wicket
context.

In the wicket context what is the actual target? A JSON packet, the
browser? Something else?

There's some confusion about the whole target concept that my brain
would be much happier with if it knew what we were targeting :)

Mouse click position

[nazeem]

Hi,

I would like to show small popup relative to the position of mouse click.
Especially when user click a link, I need to show list of options and allow
user to click on one of them. For this I need to know the position of the
link and mouse click so that I can position the popup accordingly. Please
advice how we do this using wicket.

Regards.
Naz

Form values are not submitted if form-component is initially not visible

[Joachim Rohde]

I have a listview which is displaying in each row some data within a 
form, among other things a date (as a label which is initially shown)

and a Panel containing a (wiquery-)datepicker (which is initially hiding).
Each row also has an edit-link (AjaxLink) and a save-link (SubmitLink).
After clicking the edit-link I'm hiding the date-label and display my 
panel with the datepicker.


My problem is now that after clicking the SubmitLink I'm getting a 
null-value from my datePicker.


If I am setting the visibility of my panel from the very beginning to 
"true" and omit adding my panel to the AjaxRequestTarget within my 
AjaxLink, everything

works as expected: the datepicker is returning the selected value.

What am I doing wrong here? How can I display my panel via Ajax and 
getting anyway my form-values submitted?


I tried already several hours to find a solution, searched the mailing 
list and web but I don't find any solution. So thanks in advance for any 
suggestion.


Joachim


PS:
Here are the relevant pieces of code:

My Listview:

ListView tiltos = new ListView("myList", myList)
{

@Override
protected void populateItem(final ListItem listItem)
{

Form form = new Form("form");
listItem.add(form);

// the actual date is set later in the code
final Label dateToBuy = new Label("dayToBuy", "keine 
Angabe");

dateToBuy.setOutputMarkupId(true);
dateToBuy.setOutputMarkupPlaceholderTag(true);
form.add(dateToBuy)

final EditDatePanel editDate = new 
EditDatePanel("editDate");


// if i set this to true and ommit the line later, 
everything works

editDate.setVisible(false);

editDate.setOutputMarkupId(true);
editDate.setOutputMarkupPlaceholderTag(true);
form.add(editDate);

final SubmitLink saveLink = new SubmitLink("saveLink")
{

@Override
public void onSubmit()
{
// the output here is always null if the 
editDatePanel
// is added to the AjaxRequestTarget (see 
following lines)

System.out.println("test = " + editDate.getTest());
}
}

final AjaxLink editLink = new AjaxLink("editLink")
{

@Override
public void onClick(AjaxRequestTarget target)
{
dateToBuy.setVisible(false);
editDate.setVisible(true);
target.addComponent(dateToBuy);

// this one causes my form not to submit any values
   // if I ommit it everything works
target.addComponent(editDate, 
editDate.getMarkupId());

}
};

form.add(editLink);
}

}


The markup to my listview:







01.06.2010








My panel (which is, at least I think so, irrelevant to my problem):

public final class EditDatePanel extends Panel
{

private Date test;

public EditDatePanel(String id)
{
super(id);

DatePicker datePicker = new 
DatePicker("datePicker", new PropertyModel(this, "test")) {

public void onModelChanging()
{
System.out.println("geht los jetzt!");
}
};
datePicker.setNumberOfMonths(new 
DatePickerNumberOfMonths(new Short((short) 1)));

datePicker.setShowButtonPanel(false);
datePicker.setShowOn(ShowOnEnum.FOCUS);

datePicker.setOutputMarkupId(true);
datePicker.setOutputMarkupPlaceholderTag(true);

datePicker.setVisible(true);
add(datePicker);
}

public Date getTest()
{
return test;
}

public void setTest(Date test)
{
this.test = test;
System.out.println("test   x: " +test);
}
}

Re: Url parameters: removed onClick + wrong url encoding

[Peter Karich]

Thanks Martin for your time and help!

The problem with M2.1 is that some functionality is missing/hidden:
E.g. I need
getWebRequestCycle().getWebRequest()
to guess the user language and set some caching stuff to workaround an
ajax+backbutton problem in 1.4.9.

Is this the correct way to use MountedMapper
getRootRequestMapperAsCompound().add(new MountedMapper("search",
HomePage.class));
?

But the blocker was guice, it seems to be broken (does not inject my
Provider => NPE) when using the 1.4.9 approach:
addComponentInstantiationListener(
new GuiceComponentInjector(this, Guice.createInjector(new
DefaultModule(;

I found the migration guide but could not solve the problems above

Can I implment this with Wicket table components?

[gouthamrv]

I have below requirements, I would like to know how feasible it is to
implement this with Wicket table components.

1. A web page should contain a table initially with one row. 
2. On the bottom of the table there should be some links to add row in AJAX
way(No page refresh) 
3. I should be able to clone a selected row when I click a link on the
bottom of the table. 
4. Some of the table cells should be editable 
5. Each row should contain a button on the last row, when I click this I
should be able to send the row 
values to server and update some cells. (In ajax way) 

I know Wicket has something called "AjaxFallbackDataTable". Is this solves
all these requirements? if not are there any other table implementations
available?

Re: Ajax and updating DropDownChoice model object

[jcgarciam]

I dont think you may want to do that with witcket, each html has a 1:1
relation with a corresponding Java file, having said so the Java file is
very tight to the DOM hierarchy that are wicket component (wicket:id).

It seems like you are trying to build an application with a CMS like
approach.

Re: Ajax and updating DropDownChoice model object

[jcgarciam]

I believe the problem goes that [setOutputMarkupId(true)] is called on very
late step.

Try setting the [setOutputMarkupId(true)] just right after when the
component is constructed, so the initial HTML have the id already set. After
that the wicket js should be able to locate the DOM id later on any ajax
response.

conversion is done by components not by models. you can override the

What happened to the Constructor with propertyType in PropertyModel?

[Baschir Jaghoori]

Hi,

I want to output the width and height fields of a java.awt.Dimension
object (which are integers) and tried to use the PropertyModel, but
because PropertyModel calls getWidth() / getHeight() (which return
doubles), the result is displayed as 100.0 instead of 100

It seems, that there was a constructor in PropertyModel for this case,
but it seems to have disappeared - wonder why? And is there any other
"nice" way to convert the double to int - other than to implement my own
model?

Logging sessionId for every log event

[Jeffrey Schneller]

I am trying to log the session id with every log event so that I can
trace a visitors steps in the log file.  I am using log4j and was hoping
I could use either the NDC or MDC.  I am not able to figure out where to
push the session id into the context and pop it out of the context when
using NDC.  If I wanted to use MDC, where could I put the session id in
to the map for each request?  Is there a particular wicket method to
override and put this in?  Should this be done as a servlet filter
instead [before or after OSIV filter]?

 

Thanks for any help.

For a quick fix (hopefully), I can remove the modal window from my
application.

Generally speaking, though: how do I define my modal window then if I should
not reference the underlying page directly?

Ajax and updating DropDownChoice model object

[Eric Reagan]

Hello,
 I'm having some problems getting ajax to work with a updating the data
contained in the DropDownChoice default model object. My drop down choices
are dependent upon what is entered in a text box. I can get/update the text
box just fine but when I go and shove the list of choices into the
DropDownChoice default model object on ajax update the choices are are not
displayed. If in eclipse I do an inspect of my default model object after I
set it, the proper values are returned.

target.addComponent(getForm().get("contractChoices").setDefaultModelObject(s).setEnabled(true).setOutputMarkupId(true));

where right now S is a list that I just created with a value of abc,
123.

Thank you,

Re: ERROR (Session.java:1406) - Exception when detaching/serializing page

[Martin Grigorov]

I have seen something like this when there are direct references between two
or more pages.
Very probably ModalWindow backed by Page is involved.

Hi,
  I've been exploring lot of Java CMS solutions and also frameworks. BRIX,
Alfresco I feel are good for different reasons.

 From a Web framework point of view, I feel Wicket&  I guess Sling  cut the
mark pretty well (not much experience yet with Sling).

However, with Java Community the solutions (beyond framework) finish is not
comparable to the likes of PHP giants like Drupal, Wordpress etc. I operate
in the small business market a lot , and this really hurts. I really feel
the Java.

With earlier version of Java it would get tedious and too boilerplate to
produce anything quickly fast. But with the advent of scripting languages
galore, be it Server JavaScript, Groovy, Scala ... and so many wonderful
frameworks we have not taken it to the next level to producing quality CMS.

Brix apparently will not be evolved further. which is fine; for its intent
it does a good job but what about taking this to the next level. Also,
problem with most CMS is they are content centric (ok hence they are called
CMS) may seem dumb at a glance.
..but I dont want my business model to go into a JCR repository. Perhaps the
intent of the site is to reflect the actual product&  business model in a
neat way with WebDav. Lets call it PMS (hah) for lack of a better
abbreviation. Also the ability to customize the admin module to give a
Product centric view instead of Content centric view. This allows for
greater analytic s and also then using java as an integration platform to
integrate the business model with infinite things at the back end with
pluggable extensions.

I liked BRIX for many reasons. Am wondering if people are thinking about
what I mentioned above ..also if we can take Brix further (not core) but by
adding extensions and delivering a quality complete solution that could
rival something like Drupal in the near future ...or maybe eventually!


..sorry i don't have my own Blog. You see WordPress is in PHP *wink hehe.
Get the point?! :)




Apache Lenya is working on designing our next version. We're leaning 
towards Sling and possibly using Wicket as well. If you're interested, 
we're always looking for people to help out.

ERROR (Session.java:1406) - Exception when detaching/serializing page

Hi all,

this is rather urgent. The following error is flooding my application. Below
is just the essential part of it, it's repeating itself and seems to go deep

Any ideas?

Wicket-auth annotations to hide a link problem

[Mike Dee]

I am trying to hide a link based on a user's role.  Using the example in
Wicket in Action (book), it suggests annotations can be used to do this. 
Here is what I'm doing:

public class HomePage extends WebPage
{
public HomePage()
{
add( new ExampleLink( "exampleLink", ExamplePage.class ) );
}


@AuthorizeInstantiation("ADMIN")
private class ExampleLink extends BookmarkablePageLink
{
public ExampleLink( String id, Class pageClass )
{
super( id, pageClass );
}
}
}

That doesn't seem to work, however.  Now the HomePage doesn't load at all -
almost as if the annotation were on HomePage.

Any suggestions?

Re: Java in CMS arena,..wicket to lead the way?!

[Brian Topping]

Have you thought about getting more involved with Brix?  

One of the great things about it is it isn't too centered on any one area.  It 
would be easy for you to help with a suite of plugins for doing the kind of 
stuff that you're talking about.  There are people on the Brix list that are 
talking about shopping carts right now, for instance.  Brix was originally 
designed for a company doing this kind of thing.  It's all possible, but 
there's a lot of fragmented development and not a lot of investment going back 
in.

Regarding the core, a lot of the features in core are going to be driven by 
needs in the plugins.  Hence, I would challenge you to create needs in the core 
by demonstrating those needs in the plugins.

Sometimes it's challenging on a small project to get the feedback that helps 
make development fun.  On the other hand, if the development isn't there, the 
community never grows to provide the feedback.

If you are worried about people having access to your assets, I'm sure you 
could find others that are working on things with the same feelings and you 
could start off privately.

Let's build some stuff!

Re: Wicket pages are invalid XHTML

[Emond Papegaaij]

Hi Ichiro,

If you want to enforce valid XHTML, take a look at the WicketStuff HTML 
Validator: http://github.com/dashorst/wicket-stuff-markup-validator

It automatically validates all pages served by the application and shows an 
error report for invalid markup.

retrieving HTML-templates via HTTP

[hermanhorsten]

HTML templates are by default stored side-by-side with the Java code. But is
it possible to retrieve the HTML-templates from another server via HTTP? In
the project I'm currently working on HTML-templates are published to a
dedicated template-server and the wicket-stuff is running on another server.
The templates are dynamically loaded so that changes to the template are
immediately visible. Is this feasible with Wicket and does it take a lot
work? How can I accomplish this?

Mapping DropDownChoice values?

[Benedikt Schlegel]

I have a DataTable to show a list of domain objects (named "DocumentLink").
These objects consist of a few attributes and some nested objects (e.g.
"Application").
So im displaying data mixed up from different "levels". For example, some
expressions configured in FilteredPropertyColumns are:

"name",
"application.name",
"postbox.id", ...

For filter functionality i implemented another POJO named
"DocumentLinkFilter" which doesnt have these nested objects i mentioned
above. Its just a plain object, consisting of string attributes. Now i have
the following question:

How can i set up a ChoiceFilter, which is essentially a DropDownChoice, to
write the value of the "name" property of the selected Application object
into the appropriate field of the DocumentLinkFilter object? Ist that even
possible? Or do i have to re-model the DocumentLinkFilter so it has the same
object hierarchy?

I just dont know how to go on right now.. any help is appreciated.

So long,
Benedikt*

Re: Styling pagination

[Benedikt Schlegel]

The easiest and also the most obvious way to do this is to extend the
PagingNavigator and provide your own markup.

But if you dont want to remove all components added by PagingNavigator, you
should use the same wicket:ids and component hierarchie, just change what
you need to change (replace '<' by previous or maybe a Label())

Styling pagination

[Josh Kamau]

Hi team,

How can i style the
org.apache.wicket.markup.html.navigation.paging.PagingNavigator component?

I would also like to replace the << < and >>> with words like previous and
next.

I tried to use PagingNavigation instead but i dont understand how its markup
is supposed to be.

Thanks always for your support.

Asynchronous File Uploads

[Nivedan Nadaraj]

Hi All

Has anyone had a requirement to upload huge files in an asynchronous mode? I
want to be able to upload some files which are on avg 4G plus.
I read some posts that wicket does fine with 50 plus megs. Since these are
huge files, we dont want the user to be blocked. Instead was thinking
kicking off a Job that takes these files and then notifies the user.

If wicket application can be configured to upload these files makes it easy
with just the file upload without a-synching, But if there is an elegant
solution can someone share their experiences?

Many thanks
Niv

Re: Possible bug in HttpsRequestCycleProcessor?

In HttpsRequestCycleProcessor, line 214 (Wicket 1.4.10):

is necessary or not (line 217, request could already be https). Result:
no temporary sessions.

In our scenario this causes severe trouble:
we have a Tomcat cluster consisting of 3 different nodes, every request
to a page is loadbalanced between these 3 nodes (loading of resource
files for that page, i.e. images/css/js). The Tomcats are configured to
use jsessionid for session management. As requests to resources
referenced from within css files (images) do not contain jsessionid, a
new session is created upon every single call to an image resource. With
the Session.get().bind() as mentioned above (we use https for
everything), this results in several new (not temporary) sessions for
every single page ...

My proposal would be to call Session.get().bind() in line 200, where you

Url parameters: removed onClick + wrong url encoding

[Peter Karich]

Hi,

two questions:

1. If I do the following all url parameters will be replaced with
?wicket:interface=:6:1:::

e.g. in the main wicket application class I do:
mount(new MixedParamUrlCodingStrategy("search", HomePage.class, new
String[]{"q"}));

in HomePage.java i do without ajax:
add(new Link("nextPage") {
  public void onClick() {
 // update some components
  }});

How can I avoid that search?q=test which correctly appears after a
search [1], will be overwritten with search?wicket:interface=:6:1::: ?
I would like that the user can copy and paste the url to a friend and he
can use the search (of course a new session is created + some parameters
lost but the q parameter is ok). So why not:
search?wicket:interface=:6:1:::&q=test


2. How can I use the HybridUrlCodingStrategy?
I am doing:
mount(new HybridUrlCodingStrategy("search", HomePage.class, true)); and
the problem is that searches containing hashes destroy the url or the
encoding does not work properly. So it writes the following url:

  search/q/#wicket.2
  instead of
  search/q/%23wicket.4

I searched through the code of that strategy but I think, that the
strategy works ok (it calls encode() when adding to url).
In the search form I am doing the appended code [1] and this works
correctly for other strategies.

Where could be my mistake? Wicket version: 1.4.9

Regards,
Peter.



[1]
Form form = new Form("searchform") {
   public void onSubmit() {
  PageParameters params = new PageParameters();
  if (query != null && !query.isEmpty())
   params.add("q", query);

  setResponsePage(HomePage.class, params);
   }};

Re: A bug in CryptedUrlWebRequestCodingStrategy

[Erik van Oosten]

Bjorn,

Please open a Jira issue so that the Wicket core team can track this issue.

Regards,
Erik.


Op 15-09-10 11:24, Bjorn S schreef:

Wicket version: 1.4.9 (rolled back due to AJAX problems in later release)

I've detected some odd behaviour with CryptedUrlWebRequestCodingStrategy,
specifically CryptedUrlWebRequestCodingStrategy.DecodedUrlRequest;

When using a QueryStringStrategy for mounting a page and passing certain
specific strings I was getting them back with characters missing. It appears
that CryptedUrlWebRequestCodingStrategy performs double-decoding.


We have a search system which uses + as a means of denoting requirements,
this is what happened;
When entering a search string like "car +red" it was correctly encoded to
"car+%2Bred" and passed along.

When decoding I saw that this became "car +red" and then was decoded again
to "car  red" [note double space].

I fixed this by extending CryptedUrlWebRequestCodingStrategy, overloading
the decode method and implementing my own copy of DecodedUrlRequest where I
removed the following line from the constructor;
decodedParamReplacement =
WicketURLDecoder.QUERY_INSTANCE.decode(decodedParamReplacement);

This seems to have fixed our problem though I won't guarantee that it hasn't
introduced new ones.

Hope this can get a better resolution.

Bjørn Soldal

Re: how Translate SingIn panel...

[Martin Grigorov]

1. Override SignInPanel => MySignInPanel.java. No modifications in the
methods here, just simple extend is needed.
2. Copy original SignInPanel.html to MySignInPanel.html and place it next to
MySignInPanel.java
3. Modify MySignInPanel.html however you want.

You can also create a ticket in Jira for this problem and describe what
exaclty cannot be translated.
