Re: XSS in wicket. Wicket fault or my fault?

[Paul Bors]

No need, Wicket escapes your model objects, see
Component#setEscapeModelStrings(true) for when HTML should be escaped and
thus the browser won't execute it as HTML or JS.
http://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/Component.html#setEscapeModelStrings(boolean)

That is on by default, so you should switch to using a wicket model for
your label.

See the bottom section 11.1 "What is a model?" of the wicket free guide at:
http://wicket.apache.org/guide/guide/modelsforms.html#modelsforms_1

Also, older Wicket in Action:

Re: Which is recomended way to implemen an editable repeating view

Take your pick at one of the Repeaters from:
http://www.wicket-library.com/wicket-examples/index.html

More on them in Ch 13 "Displaying multiple items with repeaters" of the
Wicket free guide at:
http://wicket.apache.org/guide/guide/repeaters.html

Or pruchase a book on Wicket such as Wicket in Action:

Singleton for empty models

[Paul Bors]

While I have re-usable panels, I don't want them to look up the component
tree hirarchy for a compound property model.



So I end up creating a lot of empty models such as:

super(id, new Model());



How do you guys manage your empty models?

Won't it make sense to have a Model.EMPTY_INSTANCE or similar?



Of course I can have Spring or some other DI handle that empty instance as
a singleton, but I am curious as to how other users solve this problem?

Re: Singleton for empty models

[Paul Bors]

Btw, in my use-case I extends FormComponentPanel since if I were to
set its panel to null or a compund property one, I would have to change my
model object to include the wicket id for the FormComponentPanel itself and
then go to the fields I need.

Inside my panel I warpped what I needed in PropertyModels.

n/m as I wrote this e-mail I realized that I don't need a

Re: onchange event always being fired before onclick event

[Paul Bors]

What makes you think that the only way to focus on something is by clicking
on it?

I would aproach your problem from a different angle. I would ask the
browser to give me whatever has the focus via document.activeElement:
https://developer.mozilla.org/en-US/docs/Web/API/document.activeElement
http://msdn.microsoft.com/en-us/library/ie/ms533065(v=vs.85).aspx

Or simply use the focus selector in jQuery:

Re: onchange event always being fired before onclick event

[Paul Bors]

Btw, your use-case sounds strange.

Why would you refresh what's in focus via some other's tag onChange?
Why not just simply refresh whatever component lost focus whenever its
onChagne is fired?

Re: Wicket Wizzard Question / Custom Overview Bars

[Paul Bors]

Find the panel you want to modify, say the WizardButtonBar and extend it:

public class MyWizardButtonBar extends WizardButtonBar {
private static final long serialVersionUID = 1L;

public MyWizardButtonBar(String id, Wizard wizard, final boolean
finishOnAnyStep) {
super(id, wizard);
addOrReplace(new MyFinishButton("finish", wizard) {
private static final long serialVersionUID = 1L;
@Override
public boolean isEnabled() {
return (super.isEnabled() || finishOnAnyStep);
}
});
}
}

Then change its HTML to whatever you want, ie MyWizardButtonBar.html I have
as:
http://wicket.apache.org";>
 
 
  
  
  
  
  
  
 


Finally, extend the Wizard itself and override the factory method you need
changed:

public class MyWizard extends Wizard {
...
@Override
protected Component newButtonBar(String id) {
return new MyWizardButtonBar(id, this, finishOnAnyStep());
}
...
}

Then change the Wizard's HTML as you please but preserve the Wicket
component tree hirarachy.
Something like this:

http://wicket.apache.org";>





[[Overview]]




[[Header]]


[[View]]


[[Feeback]]


[[Buttons]]









On a side note, I didn't like the default of the Finish button so I changed
that too:

public class MyFinishButton extends WizardButton {
private static final long serialVersionUID = 1L;

public MyFinishButton(String id, IWizard wizard) {
super(id, wizard, "org.apache.wicket.extensions.wizard.finish");
}

/**
 * @see org.apache.wicket.Component#isEnabled()
 */
public boolean isEnabled() {
IWizardStep activeStep = getWizardModel().getActiveStep();
return (activeStep != null &&
getWizardModel().isLastStep(activeStep));
}

/**
 * @see org.apache.wicket.extensions.wizard.WizardButton#onClick()
 */
public final void onClick() {
IWizardModel wizardModel = getWizardModel();
IWizardStep step = wizardModel.getActiveStep();

// let the step apply any state
step.applyState();

// if the step completed after applying the state, notify the wizard
if(step.isComplete()) {
getWizardModel().finish();
} else {
error(getLocalizer().getString(

"org.apache.wicket.extensions.wizard.FinishButton.step.did.not.complete",
this)
);
}
}
}

Re: I have not found file where per session data get store under work Folder in wicket application

[Paul Bors]

Are you after the user session or the cashed page store, page map?
https://cwiki.apache.org/confluence/display/WICKET/Page+maps

Drop the wicket debug artifact in your wicket webapp then load this URL to see 
the Wicket Debug Bar and you can get to see the Wicket Sessions Inspector.
Set this to true in your application when running in debug 
getDebugSettings().setDevelopmentUtilitiesEnabled(true);

Have fun!

Re: Modular Wicket Application

[Paul Bors]

I’m no expert, but it looks like your filter is not started right. That should 
be configured via the web.xml file.

Perhaps you could create a quick-start and package your project for us to see 
it as a whole?
Only the minimal code that produces the error should be packaged.

Re: Hybrid palette with DropDownChoice and ListView

[Paul Bors]

I don't think you need to go nuts and worry much about a ListView. Use a
Select2 instead of the drop-down and have a custom panel instead of the
plain old option. You can place an Add button or something or better yet,
check boxes and then you won't need the second list.

Suppose you do stick to old HTML components like a DropDown and a ListView.
First off, get off the list view and use a multiple Select.
Take a look at how the wicket pallet is done at:
http://www.wicket-library.com/wicket-examples/compref/wicket/bookmarkable/org.apache.wicket.examples.compref.PalettePage

All you would have to do is change the left available multi select with
your drop down.


Now, I would recommend using jQuery UI's widgets since they are easier to
use and more fun to work with (both for the developer and the application
user):
http://jqueryui.com/demos/

Have fun!

Re: Leaving page after closing modal results in browser pop up

[Paul Bors]

Have you tried setting this on your page?


Wicket.Window.unloadConfirmation = false;


It should work, and if you want to apply it to all of the modal pop-ups in
your app, consider using a header contribution that you would add to your
parent page.

~ Thank you,

Re: How to start Wizard with an active step? / Best practise?

[Paul Bors]

We need to build the WizardModel in a dynamic way. Although I think there
is a better more dynamic step too that can be used here.

So one cheap solution is to keep an enum or some sort of a definition of
your wizard steps:
public static enum WizStep {
/** Step 1 of N */ STEP_ONE(1),
/** Step N of N */ STEP_N;
...

private int stepNum;

WizStep(int stepNum) {
this.stepNum = stepNum;
}

public int getNum() {
return this.stepNum;
}
}

Then extend the wizard and build the model starting at the given step like
so:
private class MyWizard extends Wizard {
private static final long serialVersionUID = 1L;

public MyWizard(String id, WizStep startStep) {
super(id);
setDefaultModel(ediPojoModel);

WizardModel model = new WizardModel();
if(WizStep.STEP_ONE.getNum() >= startStep.getNum()) {
model.add(new FirstWiwardStep()});
}
// Keep adding the rest of the steps
...
if(WizStep.STEP_N.getNum() >= startStep.getNum()) {
model.add(new NthStep());
}

init(model);
}
}

Maybe a better approach is to create your own parent intelligent wizard
step that will skip itself in the init() or onInit() method till it get to
the Active step then you could build your model as normal.

Have fun.

Re: Does wicket:link tag work inside pages in different packages?

[Paul Bors]

Instead of using in-line  why not use a  
and then add(new Link(“homePage”, HomePage.class)); to your parent class? That 
will resolve no matter where its used from.

After all  is just a Link class at the end of the day.
Also see the examples page:

Re: DataTable's FilterToolbar generics broken

[Paul Bors]

I think you're confused.

If you want to filter a collection based on type T, then your filter your
extend T.
The idea here is that your model object type for the filter is the same as
that retrieved by the data provider.
As such you can have a POJO of the same type T on which you apply the
filtering.

Otherwise what would you filter the collection based on?
There will be no standard, will there?

Re: Question / Best Practise / (List)Model vs. (List)DataProvider

[Paul Bors]

Models:
http://wicket.apache.org/guide/guide/modelsforms.html

Data Providers (ie: Repeaters):
http://wicket.apache.org/guide/guide/repeaters.html

Long story short, a repeater's DataProvider gives you a single items model.
A model who wraps a collection, gives you a collection of items for a
single component.

Btw, this is what you want:

http://ci.apache.org/projects/wicket/apidocs/6.0.x/org/apache/wicket/request/cycle/AbstractRequestCycleListener.html#onException%28org.apache.wicket.request.cycle.RequestCycle,%20java.lang.Exception%29

Add your own IRequestCycleListener (AbstractRequestCycleListener) with
org.apache.wicket.Application.getRequestCycleListeners().add() and
implement its #onException(RequestCycle, Exception) then drop that in your
HTML comment.

Re: Newbie question : How do I display a tabbed list vertically rather than horizontally?

[Paul Bors]

Extend the Wicket class you want like the AjaxTabbedPanel in Java (Model and 
Controller) and change the HTML (viewer) as you please.

You would need access to Wicket’s source code thus if you use Maven see the 
sources classifier at:
 http://maven.apache.org/pom.html

Perhaps your IDE (Eclipse, Netbeans, IntelliJ IDEA, etc) is already configured 
to view the sources of your project’s dependencies.
If not download the sources manually from maven central or view the source code 
in the right branch online at GitHub:
https://github.com/apache/wicket/tree/master/wicket-extensions/src/main/java/org/apache/wicket/extensions/markup/html/tabs

Note the TabbedPanel.html contents:
http://wicket.apache.org";>


[[tab title]]





So create your own VerticalTabbedPanel.html and change the HTML mark-up to say 
a table but preserve the wicket:id hierarchy:
http://wicket.apache.org";>







[[tab title]]




 

[panel]






Then you need to extend the AjaxTabbedPanel java class to your own 
VerticalTabbedPanel.java say:
public class VerticalTabbedPanel extends TabbedPanel {
// In your own VerticalTabbedPanel constructors call super.*
}

From then on, feel free to use your new VerticalTabbedPanel.

Alternately you can use CSS to style the original markup of the

suggested.
I only provided this answer to you so you can learn how easy it is to override 
Wicket’s code and its markup if so desired.

Well, by hidden do you mean an input type of hidden or not present on the DOM?

You’re attaching the submit event so who fires that?

Re: Ajax Form Submit via jquery plugin / javascript

[Paul Bors]

Instead of calling form.submit() from your jQuery, call 
${‘#someButtonID’}.click() or whatever, then register your event under the 
button’s onClick in Wicket.
You can have that button shared, or you can write your own Behavior to submit 
the form via a hidden button (i.e.: X and Y coordinates set to negative so it’s 
way off the page as well as its display property set to hidden).

Those are just couple of ideas.

Re: Feedback/Error message.

Have a look at the Sortable DataTable:
https://cwiki.apache.org/confluence/display/WICKET/Simple+Sortable+DataTable+Example

It has a build in message for when there are no results matching your
filter or the model is empty.
You can override it to display your own custom message as well.

Re: Custom Pagination

[Paul Bors]

You're half way home.

You extended PagingNavigator but forgot to read its code.
See line 150 of PagingNavigator or better said the newNavigation() method:

/**
 * Create a new PagingNavigation. May be subclassed to make us of
specialized PagingNavigation.
 *
 * @param id
 *The id of the navigation component
 * @param pageable
 *the pageable component
 * @param labelProvider
 *The label provider for the link text.
 * @return the navigation object
 */
protected PagingNavigation newNavigation(final String id, final
IPageable pageable,
final IPagingLabelProvider labelProvider)
{
return new PagingNavigation(id, pageable, labelProvider);
}

In your class, override that factory method to return the type of
PagingNavigation you want.


Also, get more familiar with that component's code. Read and understand how
those classes are related to each other:

Re: Mailbox component

[Paul Bors]

This is Wicket not GMail :)

Perhaps you could write your own?

Integrate something like this in your own page/panel (or ask Google for a
better one):
http://w3lessons.info/2013/05/13/gmail-style-message-inbox-design-with-jquery-css/

Then you can use templates to send those e-mails:
http://www.wicket-library.com/wicket-examples/mailtemplate/

I haven't tried any of this so you're on your own.

Please refrain from asking such general question in this mailing list.
If you have a specific Wicket question, then by all means start a new
topic/thread/post.

Foundation integrated in wicket

[Paul Bors]

Has anyone integrated Foundation from http://foundation.zurb.com/ in Wicket?

Each time I search for it the search engine comes back to Apache's Wicket
Foundation :)

Re: Can I process a POST with simple non-Json parameters using wicket-restannotations

[Paul Bors]

I think you might be looking for the query parameters of the 
http://ci.apache.org/projects/wicket/apidocs/6.0.x/org/apache/wicket/request/Request.html
 class.

See Chapter 9 of the Wicket Guide:
http://wicket.apache.org/guide/guide/single.html#requestProcessing

You can get to the Request from any of the Components on your page. Thus you 
can have a bookmarkable URL and in the constructor of that page you can grab 
the request and extract the parameters from it.

Do you care if the request is POST or GET?
Wicket abstracts that out for you via the query parameters.

Re: Mailbox component

[Paul Bors]

Suppose you take the jQuery Table and style it something like this (in a
responsive web 'theamable' manner):
http://w3lessons.info/2013/05/13/gmail-style-message-inbox-design-with-jquery-css/

Suppose you integrate it in Wicket and have it functional and suppose you
want the following basic features implemented:
* SMTP/POP and IMAP support
  * Properties or settings screen to configure the basics
* Add Star / Unstar Messages
* Delete Single Message
* Delete Multiple Messages
* Mark as Read
* Mark as Unread

One would have to handle a pretty good abstraction of the actual
interaction with the mail server which might or might not support all those
features. And if a feature is not supported it should be disabled.

I think this is at least a week's effort.

Right, that’s all custom to your web app.

Suppose I want to take your SASS and apply it to my form field, more precisely 
a Wicket class.
Suppose I want to be able to “theme” the entire look-n-feel of the web app and 
only have to customize the theme and not the entire product.

That’s what I mean.

Re: Referencing DataTable rows within the table column header

[Paul Bors]

Hey Ephraim,

At Knoa for the console code I created an API around those components.
You don't have to re-invent the wheel, all you have to do is get familiar
with the console commons and which DropDown component to use.

Remember wicket is a component driven framework similar to Swing.

I would recommend using one of the Ajax enabled drop downs and override the
method to refresh the data table rows of interest. There are plenty of
examples in the console's code base... look at how other table such as the
ones for the End User attributes are refreshed or how the edit button in a
table cell will turn the table row into form components. Use the same
principle.

Also, if this is just a filter toolbar, then look at how other Ajax filter
toolbars work and you won't loos focus of the drop down since it's Ajax
that does the refresh.

If you are to re-implement this from scratch and re-invent the wheel you
can also but I won't recommend it.
Just look over the current available components in your commons API and use
the appropriate one, or extend it and make it do what you need.

Martin was referring to the event mechanism build in Wicket documented in
the Wicket Guide at:
http://wicket.apache.org/guide/guide/single.html#advanced_1

But for a simple filter toolbar you don't need to get that complicated.

Re: Referencing DataTable rows within the table column header

[Paul Bors]

Another piece of advice,

Avoid unnecessary casts (Wicket 6 supports generics) and try not to use
code to navigate the wicket component tree unnecessary like this line of
code:

WebMarkupContainer container = ((WebMarkupContainer)
dropDownChoice.findParent(DataTable.class).get(1));

Get familiar with the best practices documented at:
http://wicket.apache.org/guide/guide/single.html#bestpractices

You should give the free guide a read back to back and treat it as your
bible until you get a bit more intimate with Wicket :)

Other resources available for you to learn and master Wicket are the Wicket
Stuff (http://wicketstuff.org/) and the examples at:
http://www.wicket-library.com/wicket-examples-6.0.x/index.html

Get familiar to those as well.

For a filter toolbar see:
http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.DataTableFilterToolbarPage;jsessionid=03E1374082C8198F0F052CED6E54F7A1?0

Although is not using a drop-down but you'll get the idea :)

Re: ComponentNotFoundException when googlebot scrapes wicket page

[Paul Bors]

Well, you have the wicket component tree path to what's not found:
titleBar:menu:2:link

The 3rd (index 2) menu link was missing at the point your page was rendered.
Start thinking about how your 'menu' component could miss that from the
mode.

Or perhaps someone used the back-page button and your page was not in the
page store?

Re: ComponentNotFoundException when googlebot scrapes wicket page

[Paul Bors]

ie: How do you create the menu links?
Where does the model come from and are those links dynamic?

Re: AuthenticatedWebSession.authenticate() not being called

[Paul Bors]

Irrespective of the UI, have your read through
http://wicket.apache.org/learn/projects/authroles.html ?

Most likely the wicket-auth-roles login page is using one of the documented
annotations that makes all the difference for you. Try to place that
annotation on your page (I haven't read your code...)

Re: Transpose html table

[Paul Bors]

If you want to "transpose" your table (ie: change the rows and columns)
then it turn this implies that you want to change the structure of the
table both the format and the model.
ie: You need to provide new columns and new data model.

You would do so in 2 steps:
1) Create the new table with the new columns
2) Provide it the new data model

Then use the addOrReplace("tableId", transposedTableRef) and you're done.

Otherwise... look at transposing your table in jQuery alone on the client
side and not on the server side.

Re: Mapping two UI componets to Single Model

[Paul Bors]

Please reffer to the free user guide, section 12.9 Creating complex form
components with FormComponentPanel at:
http://wicket.apache.org/guide/guide/single.html#forms2_9

In short you need to create your own compound FormComponentPanel that
encapsulates both from components and accepts a single model. Then you
would take that model and pass each individual part of it to the
corresponding form component you want.

Re: How to get this URL pattern working in newer versions of Wicket?

[Paul Bors]

Hey Steve,

You should not mount it yourself given the long session ID of
'a79c7348-6c8b-
4912-8cc7-3b4419344f7f' since that will change anyhow.

To understand how Wicket handles the URL mapping see the user guide's
Chapter 10 "Wicket Links and URL generation" at:
http://wicket.apache.org/guide/guide/single.html#urls

I guess you want to provide your own IMapperContext?

Re: alternative solution for addOrReplace()?

[Paul Bors]

Why not use Ajax?

addOrReplace() is really for when you need the full request cycle and have
the page rendered on the server side. With Ajax you get your target for
which you can add all the components you want to refresh on the page.

Given the day and age we live in, I don't think there is a need to even
worry about browsers that do not support Ajax. Than again, that depends on
your product's requirements.

Otherwise, you can keep on using addOrReplace() but stop using instaceof
and start using Generics.
If you need an example code-snippet of that let me know and I'll dig some
out for you.

Re: Could not clear select2Choice component model value.

[Paul Bors]

You can also ask the developer via:
https://github.com/ivaynberg/wicket-select2/issues

You should probably take a look over the open issues so that you are
familiar with that other developers faced. Maybe one of those issues might
be a road block for you?

Although you will get a faster reply from Igor or another Wicket developer
via this list :)

Re: alternative solution for addOrReplace()?

[Paul Bors]

I think you might have over-complicated your design.
Your use-case is quite simple, you have user input that filters the
display. It might be that there are a lot of panels to be updated but then
again it should be simple to update the parent which in turn delegates that
responsibility to the children.

Take a quick look over how Decebal implemented his Wicket-Dashboards as in
his project the entire dashboard is refreshed when adding a new panel which
in turn can be quite complicated.

His code and examples are at:
https://github.com/decebals/wicket-dashboard

Study his design and see how much of that you can apply to your page.

Otherwise I suggest you get rid of the addOrReplace() and move that logic
into your onBeforeRender() methods for those panels to update themself.

Re: Unit testing RadioChoice with AjaxFormComponentUpdatingBehavior

[Paul Bors]

Since you want to test a AjaxFormComponentUpdatingBehav
ior and not a standard form component (non-ajax) you don't use
formTester.selectRadioChoice( "propertyType", 2 ) you have to create the
AjaxTarget and etc.

See "Testing AJAX behaviors" section at:

Re: PropertyModel / PropertyResolver / Map or List access

I think that should have worked as per:

Label label = new Label("firstChildName", new PropertyModel(person,
"children.0.name"));

Re: Wicket6 setResponsePage() stackoverflow error.

I'm no expert but it looks as if your filter from Liferay is looping calls

RE: Validating form components in a refreshing view

[Paul Bors]

For example of how you could validate a form given multiple form fields take a 
look at how EqualInputValidator is implemented.

You would have to keep references to the form fields that are related and 
return them as an array via IFormValidator. getDependentFormComponents() of 
your own IFormValidator implementation. Then you can add as many of those you 
want to your form.

Wicket form processing:

 ---  --  -  --    
 
| Start | -> | required | -> | convert | -> | validate | -> |  push  | -> | 
onSubmit() |
|   ||  checks  ||  input  ||  input   ||  input || 
   |
 ---  --  -  --    
 
  |  ||  |  

 fail   fail fail   fail   
--- 
  |  ||  || 
onError() |
   - - - - - - - - - - - - - - - - - - - - - - - - - - -> | 
  |
   
---

I recommend reading "Wicket in Action" (http://manning.com/dashorst/) or any 
other books listed on Wicket's website (http://wicket.apache.org/learn/books/).

Hi Josh,

you're right,
I haven't put any in this example because I am really not sure how I should

If I choose a FormValidator with the FormComponents textOne and textTwo, I can 
just compare the values of one row.

I will extend my example later.

Update JavaDoc for AbstractChoice#setType(java.lang.Class)

[Paul Bors]

How should we as Wicket users request updates to JavaDocs as we come across 
them?

AbstractChoice.setType throws an UnsupportedOperationException but that's not 
reflected in its JavaDoc at:
http://ci.apache.org/projects/wicket/apidocs/1.5.x/org/apache/wicket/markup/html/form/AbstractChoice.html#setType(java.lang.Class)

This is not mentioned in the migration guide. Perhaps a note should be added 
next to the one about AbstractSingleSelectChoice:
https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-%2528RC6%2529AbstractSingleSelectChoiceusesemptyStringasvaluefordefaultchoice

There is no need to throw a RestartResponseAtInterceptPageException.
Simply redirect the user to the log-in page:

Session.session().invalidateNow();
setResponsePage(LoginPage.class);
}
};

Hi,

The LogoutPage in the application I work on is quite simple:
- first we invalidate the session with session.invalidateNow() like you do
- second we throw a RestartResponseAtInterceptPageException with the Page we 
want the user to go to after the logout process (actually we use it with the 
class of the Page we want, but you can pass it an instance of a Page).

Hope this will help.

cssHeadLink.add( new AttributeModifier("href", new 
Model(getSkinStyleSheet())) );
htmlTag.add(cssHeadLink);
}

Then have getSkinStyleSheet() return the name of the CSS file or use any other 
kind of IModel.

Notice the above example also shows the use of the 
TransparentWebMarkupContainer used to change the HTML document's language in a 
similar manner only it will not be part of the component path for pages that 
extend BasePage. Here, getUserLocale() returns the Locale of the logged-in user 
whose ID is stored the Session.

Subject: [1.5] [6.0] dynamically named CSS, JS & images resources

Good evening,

I'd like to contribute CSSs & JSs to my  for which names I don't know. 
More precisely, I'd like to be able to download a .zip, unzip it and contribute 
its CSS & JS content to the , plus being able to display the images of 
the zip thanks to the links in the CSS.

Regarding the downloading and unzipping steps, it's easy. But for the header 
contributions, I can't figure out how to do that since :

1) I don't know the names of the CSS & JS files before download

2) the CSS files link to the images using their regular names, but Wicket 
appends characters of its own to their names.

What I'm trying to achieve is to be able to switch (at run-time) my app's theme 
by downloading a new one on a themes website, like 
http://www.freecsstemplates.org/

I use Wicket 1.5.7 but a solution for Wicket 6.0 is OK as well.

Any help will be much appreciated.

Regards,

Pierre Goupil

RE: I think it's time for a new book.... Igor and Co ?

[Paul Bors]

I second improving the current code documentation as I recently migrated a
mid-size project to Wicket 1.5.7 from 1.3.7 and I've notice myself having to
dig into the framework implementation more often than normal because of the
weak or at times wrong JavaDocs.

I won't mind submitting small patches if someone would point the way. Last I
asked I was told to submit a push via git hub. Is there a wiki page on how
to submit such code changes patches to a wicket branch?

At the same time I do feel that a book explaining the inner works of Wicket
will also benefit everyone to better understand the framework faster and be
able to contribute as needed. I remember couple of years ago when I first
started working with Wicket and how lost I was until after I read two books
on the subject just to learn how to use it.

That's my 2 cents :)

Putting in my 2 cents.

I'd rather see more people put in time and effort to submit patches for
documentation that would reduce the need to dig into the guts of Wicket.

Now that I'm more familiar with Wicket, I'll try to start doing this.  I
hope others will too.

RE: Wicket Layout Design

[Paul Bors]

You can try using a TransparentWebMarkupContainer so that you won't always
have to add them to the page hierarchy and only override your factory
methods when you need to.

For a code-snippet example see this thread:

Thanks Jesse for your reply.

The only drawback of this method is that I will need to override theses 3
methods (createNewHeader, createNewFooter...) in all pages that extends
"BasePage.java".Ideally I would like to avoid copying code but I think it's
the cleaner way to override layout components.

If you want to try GitHub:
1) create an account at GitHub (https://github.com/)
2) go to https://github.com/apache/wicket and click the "Fork" button
3) clone the fork locally: git clone
https://github.com/MY_ACCOUNT/wicket.git (replace MY_ACCIUNT with your real 
username.)
4) make your improvements in the code
5) git commit
6) git push
7) go to https://github.com/MY_ACCOUNT/wicket and press the "Pull Request" 
button

That's it.

RE: Where to add javascript in html pages which follow inheritance relationship.

[Paul Bors]

Well, it appears that your Page2.html and Page3.html are base pages (root
classes to extend from) since you used  (something will
extend from those pages). Thus your hierarchy tree would look like:

Page2.html (root)
  Page1.html (child: if you extend Page2)
Page3.html (root)
  Page1.html (child: if you extend Page3)

Also, you should add a  to the HTML file(s) that are your base
classes (the ones you declared  in).

See this example on Creating layouts using markup inheritance from Wicket's
website:
http://wicket.apache.org/learn/examples/markupinheritance.html

Hope that helps!

RE: dynamic control of location of panels on page

[Paul Bors]

Well, if you use a repeater it will go through its model in the order you
added the items to it.
If you want to control where on the page they go, then you would need some
kind of dynamic template or overlay.

For that I used HTML tables with North, South, Center, East, West table
cells and I add the container to all 5 cells but hide the ones that I don't
want to see.
It's a bit extensive as the page map grows, but it works and it should be
okay to get you started on a better solution :)

For some other dynamic components I used Velocity as their template:
http://en.wikipedia.org/wiki/Apache_Velocity

This is the Wicket project on it:

Subject: dynamic control of location of panels on page

Let's say we want to have a number of widgets on the page. But we want to be
able to dynamically define what widgets are shown, and in what order they
appear on the page.

So I can create a bunch of panels, each with their own html, and add those
panels to a container to display on the screen. But how do I  control the
order of them? If I put them in a list, will they be drawn in the order they
were added to the list?

I'm following this example:
https://cwiki.apache.org/WICKET/page-with-dynamic-components.html wicket
dynamic content 

Will this type of solution work even if the widgets are of different widths?
Can we still control the layout in the html if we never know what widgets
are shown?

I hope I explained it properly.

Make use of the EmptyPanel class for the null or empty models. You could

I haven't used the GridView directly so I can't help you with it

RE: How to update the treetable

Since Wicket's TreeTable uses Java's javax.swing.tree.TreeModel, I would
check out Oracle's tutorial on How To Use Trees (JTree).

More precisely the Dynamically Changing a Tree section:

Subject: How to update the treetable

I created a treetable with a treemodel based on database schema. I am trying
to refresh the treetable so that it will change it's data after some db
update.
I update viat the button event.the button event work but treetable doesn't
change.
To create treetable i have this on my page:

treeTable = new TreeTable("treeTable", createTreeModel(), columns);
treeTable.getTreeState().setAllowSelectMultiple(true);
treeTable.setRootLess(true);
treeTable.getTreeState().collapseAll();
creatForm.add(treeTable);

the createTreeModel code:
protected TreeModel createTreeModel() {
DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode();
initTree(roleList, rootNode);
TreeModel treeModel = new DefaultTreeModel(rootNode);
return treeModel;
}

i add the button event like this:
protected void onSubmit(AjaxRequestTarget target, Form form) {
roleList.clear();
treeTable.updateTree(target);
target.add(getForm(),treeTable);
}

Any idea or reference to documentation that explain this?
thanks.

RE: Multi row Tabs

[Paul Bors]

You can change the look-n-feel of any Wicket component by simply extending
the Wicket class, and either modify the HTML and/or the CSS.

If you modify the HTML make sure you preserve the wicket component tree
unchanged since the super class will break at runtime if you shift the HTML
code around and break the hierarchy of the wicket component tree.

I extended from AjaxTabbedPanel and have two panels that would either render
the tabs horizontal or vertical and when they reach the end of the page they
will wrap to the second row or column.

The look-n-feel as well as horizontal or vertical orientation is handled by
different CSS classes via the float attribute (and many others) inside my
package. For example:

Horizontal tabs from left to right use this CSS class:
div.horizontalTabpanel div.tab-row li.selected {
float: left;
...
}

Vertical tabs from top to bottom use this:
div.verticalTabpanel div.tab-row li.selected {
float: top;
...
}

One class sets the CSS of the main panel to either horizontalTabpanel or
verticalTabpanel.

RE: RadioGroup

[Paul Bors]

Have you taken a look at the Wicket-Examples project's component references
as linked from Wicket's website under the Learn section on the left panel?
http://www.wicket-library.com/wicket-examples/compref/

More specifically the RadioGroup and Radio:
http://www.wicket-library.com/wicket-examples/compref/wicket/bookmarkable/or
g.apache.wicket.examples.compref.RadioGroupPage?2

You need your form, then add to it a RadioGroup whose model holds on to the
active Radio selection and then add all the Radio buttons to the RadioGroup.

The RadioGroup can be a  tag and if I am not wrong even a
 tag.

Same concept applies to the CheckGroup and Check, not to be confused with
CheckBox.

Hope that helps!

wicket-examples and run them locally on your computer. See the "Provide a

RE: Basic JUnit Test

[Paul Bors]

Also get familiar with the API for the WicketTester that extends 
BaseWicketTester.

There are quite a few useful methods that can aid you during unit testing such 
as BaseWicketTester#debugComponentTrees() which will output the wicket 
component tree.

In our unit tests we extended from WicketTester and added a dumpPage() method 
that would give you both the output of BaseWicketTester#debugComponentTrees() 
and that of BaseWicketTester#getLastResponseAsString() so a developer can see 
both the Wicket component tree and the HTML or whatever the last response was 
(Ajax, etc).

When I write unit tests I use those two methods extensively as I would need to 
know both the component path in the tree and the expected output or the last 
response.

There are plenty of other helper methods there as well.

RE: Generic search form/panel implementation

[Paul Bors]

We have some proprietary small projects in our product developed in Wicket
that matches your request.

I had to develop something similar for a form that draws itself on the
screen in a tab panel whose meta-data is in XML which in turn is uploaded to
the product as a plug-in at run-time. To get this up and running took a good
3-4 weeks of development time.

Thus what you're asking for is possible and you don't have to restrict your
meta-data to XML, feel free to use annotations if it's all done in Java
code. You should keep in mind that Wicket depends a lot on the MVC, your
only limitations are really the model object(s), the custom form validation
and submission actions (error reporting, localization etc).

The model I overcome by using generic objects for each form field in a tree
structure with IDs for each element and using this tree as the model of the
form which in turn is used by the form submission after validation succeeds
to grab the user input. The same tree carries the UI definitions and default
values as loaded from the XML file.

For the custom form validation, I allowed the developer of the XML file(s)
define a validator given the well known wicket classes and their API plus
the specific domain ones we have developed in-house and pass primitive
arguments to their constructors (ie: maximum character size for this text
field is x).

Since I'm using this on a single page, I didn't have to worry about the form
submission and error but I could have designed this as an interface and have
the client code implement it form different forms and pages, I think is
doable.

Hi,

I am trying to implement a generic search form/panel in Wicket. The form
should allow searches in several fields in an Entity (using the DAO pattern)
in order to filter the output of a ListView or a DataView. What is the best

but I haven't really seen any real example.

Did anyone implemented such a thing? Some pointers would be nice.

[Paul Bors]

BTW, if you get a NPE on RequestCycle.get() then you most likely place this
code outside a Wicket Component like a Page.

Try moving it to a page first and see if you grab a reference to the request
object. If you do, then pass it as a parameter to your other method/class.

RE: Is there a way to search component by its wicket ID ?

[Paul Bors]

In my unit test code I use:

  
com.googlecode.londonwicket
wicket-component-expressions
0.2.0
test

  
org.apache.wicket
wicket
  

  

Or see:
http://code.google.com/p/londonwicket/source/browse/repo/com/googlecode/lond
onwicket/wicket-component-expressions/?r=61#wicket-component-expressions%2F0
.2.0

They are a group of Wicket users from London and their two static method
tool allows you to use regexp in the component path as well as filtering by
a component type such as a TextBox and its model such as
Model("Hello World").

I don't think the new version of Wicket has this flexibility build in
WicketTester, but looking over the code of
BaseWicketTester#getComponentFromLastRenderedPage() and
BaseWicketTester#debugComponentTrees() you can implement your own method to
iterate through the component tree and return a reference to the component
you want.

RE: Is there a way to search component by its wicket ID ?

[Paul Bors]

If you use wicket-component-expressions from com.googlecode.londonwicket you
can get to the list of all the components on the page that have that
"username" id via a regexp of "**:username", but as James mentioned earlier,
the ID is not unique and your wicket component tree might have such multiple
nodes (hence why wicket-component-expressions gives you a list of them).

I normally know that my panel has only one such component by the ID since I
developed it, so if I attach it to my page inside a panel with an ID like
"myPanel" then I use "**:myPanel:**:username" and I also filter by the
component type such as TextField.class to narrow down the search.

That's not production code, is unit test and I'm assuming that's the context
of your question. By using such regexp, I found myself refactoring the unit
test code less when shuffling panels on a page.

Because the id is unique only within the markup container of a component.
It need not be unique in a page. This is by design.

RE: How to control IMG/CSS URL-Rewriting in mounted pages?

[Paul Bors]

Wicket rewrite the SRC attribute of the image as relative to your webapp 
context unless you declare that image as a wicket component, give it a 
wicket:id and then use a ContextImage.

Thus you would turn a  to a .

If you do so, then you can still preserve the "wrong" src relative path of 
"../images/image.jpg" so that your web developers can see the images while 
editing the static HTML resources and when you run the web-app Wicket will take 
care of fixing that URL for you no matter at what point you mount the page.

If you have too many such images and refactoring might take you too long, then 
consider write your own Custom Wicket Tag Resolver for an attribute of the img 
HTML tag and override what the framework does for you (do call super) by 
changing the src attribute in a similar way ContextImage would do it for you.

For example see this article:
http://sanityresort.blogspot.com/2011/08/creating-custom-wicket-tag-resolver.html

Or see how other such resolvers or AttributeModifer are used by Wicket itself, 
you can start with the AutoComponentResolver.

Alternatively, how can I tell Wicket that the web root has a different prefix

RE: WicketRuntimeException: "Submit Button ... is not enabled"

[Paul Bors]

As an idea, I tend to keep the panel edit/view state as a boolean and then
toggle the label on the button and control the behavior of the button press
via an if-else statement in the onSubmit() of the button.

This helps because I only have a single Edit/Save button and I toggle from
labels to form fields on the fly controlling those components via
AjaxFallback*** implemented in a single refrechPanel() method that calls
setVisable(editMode) for all the components that are to toggle or hide.

Also you can do this to the DataTable rows when necessary similar to how the
Editable tree table works:
http://www.wicket-library.com/wicket-examples/ajax/tree/table/editable?3

I get away with all this because I have my own generic labeled form
component that can toggle from a label to a form component and have a
 html tag as well as an Help icon and feedback panel associated with
it.

Subject: Re: WicketRuntimeException: "Submit Button ... is not enabled"

It is true that we have multiple buttons on our form that we are
disabling/hiding selectively.

Our scenario: a panel that contains the button "Edit", and then when it's
clicked, the panel opens and "Edit" is replaced by two other visible buttons
- "Submit" and "Cancel". "Edit" is gone. We need this dynamic behavior to
enable rich, "self-changing" forms.

Example:

add(new Button ("editButton"){
  @Override
 public boolean isVisible() {
 return showeditbutton;
}
@Override
public void onSubmit() { 
  showeditbutton = false;// hide this one
  showsavebutton = true;   // show the others
  showcancelbutton = true;
}
}

These are global variables/flags on the form. 

So given this "self-changing form" requirement, what's the fastest way to
get rid of this intermittent "Not Enabled / Visible" error? Is there a way
to turn off this validation in Wicket?

When I try this on Chrome or Safari it works fine.

How to resolve this with IE9?

RE: Static web page localization

[Paul Bors]

Another idiom is to attach a wicket:id to that HTML tag, and in your Java code 
use a WebMarkupContainer with an AttributeModifier to change whatever attribute 
you would like. Of course the IResource and children might be a better approach 
since it does the work for you :)

~ Thank you,

Hi,

You may use Wicket IResource that should serve the SWFs dynamically.
See http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/
for an inspiration.

RE: Nested form submit problem

[Paul Bors]

Sounds complicated, why not just setVisible(false) when you want to "delete"
or hide one of those questions (aka form fields)?
Also, I don't think you need to use nested forms here, unless you wrap each
question in a panel and within in a form.

Refer to this wiki page for nested forms and their behavior:
https://cwiki.apache.org/WICKET/nested-forms.html

Is hard to follow the code example you gave but if I understand your
use-case right and if you want to add different questions within a form I
suggest you use a DataTable and a dynamic DataProvider that would be
populated with a list of Panels that hold on to each of the labels and form
fields with the questions you want to show (no need for an inner form unless
you want the question to be answered by itself). When you want to hide one
of them simply call setVisible(false) and use Ajax to refresh the DataTable.
If you want to change the questions, simply change the list of Panels and
make sure each form field has its own model (or use CompoundModel if you
want).

Hope that helps :)

~ Thank you,
  Paul Bors

Subject: Nested form submit problem

Hi,

I have the following use case. I have some questionnaires and a couple of
questions belong to every questionnaire.
I created a nested form component contains two forms. First does nothing
just has some buttons (save,delete,cancel,reset) and contains as many child
forms as the number of questions.
So it's fine and almost everything work. My problem is when I want to delete
the items and click delete button then the inner form's onSubmit event also
fires although I set the delete.setDefaultFormProcessing(false) behaviour on
delete button. Same is with reset and cancel button. Both of them fires
inner form's onSubmit event.

RE: Nested form submit problem

[Paul Bors]

Why not use "onchange" and validate the field when the user changes the
input?

All you would have to do is add your validators as you would normally do,
then create Ajax*** form components and in their callback method for
onError(target) refresh your feedback panel.

A text field with this design applied to it will validate the user input for
each character typed, use a different JS event for other behavior.

For code examples see:
http://www.wicket-library.com/wicket-examples/ajax/form

Hi Paul,

The problem related to AjaxFormSubmitBehavior  behaviour. This fires eform's
onSubmit event.
My original goal was to create field level validation with Ajax nothing
more.
The code above looks for a description belongs to the entered value and
displays it.
If the entered value validation failed then warns the user immediately. 
BTW if I turn of afvb setDefaultFormProcessing to false then the field level
validation does not work.


---
  AjaxFormSubmitBehavior afvb=
new AjaxFormSubmitBehavior(eform, "onchange") {
 
 
@Override
protected void onSubmit(AjaxRequestTarget art) {
HrpBbheertk ertk = (HrpBbheertk)
eform.getModelObject();
String k = ertek.getValue();
customBo.getDaoSession().beginTransaction();
HrpBbhepar5PK pk = new HrpBbhepar5PK();
pk.setCompany(ertk.getHrpBbheertkPK().getCompany());
   
pk.setAkodszam(ertk.getHrpBbheertkPK().getAlaptipus());
   
pk.setDkodszam(ertk.getHrpBbheertkPK().getDimenzio());
   
pk.setDekodszam(ertk.getHrpBbheertkPK().getDimenzioelem());
if (!k.isEmpty()) {
pk.setDertek(Short.valueOf(k));
HrpBbhepar5 hepar5 =
customBo.find(HrpBbhepar5.class, pk);
if (hepar5 != null) {
   
dimenev.setDefaultModelObject(hepar5.getDertekmegnev());
} else {
dimenev.setDefaultModelObject("");
}

}
if
(customBo.getDaoSession().getTransaction().isActive()) {
   
customBo.getDaoSession().getTransaction().commit();
}

art.add(dimenev);
art.add(fb);
}

@Override
protected void onError(AjaxRequestTarget art) { 
art.add(fb);
}

};

RE: Pre-Select DropDownChoice Selection, but No Model yet

[Paul Bors]

Drop downs are some of the difficult ones to get at first, but once you
understand one of them you're good to go!

See:
http://wicket.apache.org/learn/examples/dropdownchoice.html (the "Selecting
a default choice")
https://cwiki.apache.org/WICKET/dropdownchoice-examples.html

Or see the FormInput live example:
