AW: Nested forms in WizardStep

[Patrick Davids]

Hi Dirk,
on selecting your radio choice, do an ajax request and disable your inner Login 
Form depending on the chosen value.

In this case, it won't be part of the form submit, which is executed by the 
wizard next click.

This also should happen after your login is done by your ajax button.
After login succeeded, just disable the inner login form, and the user should 
be able to proceed.

Betreff: Nested forms in WizardStep

Currently we use the Wizard/WizardStep classes from wicket-extensions to set 
required data for an object (in our case a checkout process with some user 
Information, e.g. addresses etc.).
The first step contains a Login form with two "required" input components for 
the credentials and a separate "Login" button and a Panel with two ratio 
buttons where the user must decide whether to go on without login
(anonymous) or to register a new user account.
Only the values for the ratio buttons should be triggered by this step with the 
"next" button.
The Login itself should be triggered with the additional "login" button which 
is not part of the ButtonBar.

As far as I know it's not good to have nested forms. We don't need to have 
forms inside our steps actually, since the Wizard itself has a form already.
I've noticed that if the user hits the "next" button, the form validation for 
the login form ist triggered as well, but it should not. The form processing 
for the login form should actually not part of step, but the "login container" 
must be part of the view.

What is the best solution to implement this scenario? I implemented the step 
without an additional form component and used an AjaxButton. In 
AjaxButton#onSubmit I implemented the authentication stuff.  But further on I 
got some problems with updating the current state and how to go on to the next 
step.
Also I've noticed, that pressing the "next" button would require some input for 
the credentials. So I'm a bit confused now.
I hope, I could express myself clearly.

Could someone give me some hint? Thank you very much.

clearInput() if FormComponentPanel does not delegate to its inner FormComponents

[Patrick Davids]

Hi Wicket Pros,

is it bug or an feature, that FormComponentPanel is not overriding 
clearInput() to delegate the clearing to its inner FormComponents?


For me, it should behave the same way, when extending FormComponent.
But I'm not sure here about consequences...

(As I can see... Form.clearInput() features this by visiting its inner 
FormComponents.)

adding FeedbackMessages in onBeforeRender()

[Patrick Davids]

Hi all,
is there any way to add a message when onBeforeRender() is called?

I have a behavior for a special use-case which does some checks and 
provides feedback to the user when a check is unsuccessfull.


But I get a
org.apache.wicket.WicketRuntimeException: Cannot modify component 
hierarchy after render phase has started (page version cant change then 
anymore)


I know this restriction... but I need this kind of check on render-time 
not on configure-time of the component due to visibility issues.


If someone has an idea how to fake "onBeforeRender()" some how to get my 
feedback message... this would be great.


Thanx and best regards
Patrick

Re: Use a Factory to create a Panel (Yay or Nay)?

[Patrick Davids]

> I have at times used factories and then found that they made some 
simply things more complicated


I agree... you will loose the feature to sub-class and override 
onConfigure() or onBeforeRender() of your components.


And what I also encountered using factories, when having sub-classed 
model-objects and you want to choose as specific component depending on 
the model-objects subclass, you run into the "unpack on construction 
time" issue, which is also not that good.


And if you want to use shared models for your components and forward 
your model to your via factory constructed component, you will get type 
safety warnings.


e.g. factoryMethod(IModel personModel){

if(personModel.getObject() instanceof Employee){
		return new EmployeePanel((IModel)personModel);//type safety 
warning

}else{
...
}

}

All this points are somehow "code smells" to me and from the experience 
of the last years I more and more agree with the "bad practice" not to 
use factories for components.


But I never used Spring / SpringFactories... maybe you wont run into the 
described issues... not sure here.


best regards
Patrick

Hello,

I have at times used factories and then found that they made some simply
things more complicated. Eg. I could no longer simply override
isEnabled() or isVisible() methods to suit the page I was added the

unless I see a real advantage.

Hi,

I wouldn't use a factory for each and every component (e.g. label).
But any sufficiently large Wicket project will benefit from separating
it into separate parts which very light interdependencies only: a
plugin-based architecture.

If you're using Spring factories, you just have to take care that no
references to Spring beans leak into the components - something you
have easily with inner classes (as in the example listing 15 in the
Wicket guide).

Apache Isis uses factories to provide custom UI for almost any part

BrixCMS also uses factories to create tiles.

The containing 'normal' formComponents have written the parameters
into their models, which are changing properties of the 'main'
modelObject.

For the FormComponentPanel the following is a noop:
setConvertedInput(getModelObject());
...
updateModel();

I'm doing it this way, because the formComponentPanel hasn't anything
to convert actually, its model object stays the same.

usuallly a FormComponentPanel is used when you want to combine the

MultiFileUploadField and DateTimeField.

But you can also use it for validation of whole model objects:

PersonPanel extends FormComponentPanel {

The modelObject should be the one before the form submit, no? Because
Form#updateModels() is called after the conversion and validations.
By calling the line above you basically ignore the submitted parameters.
I am missing something in your idea. What is it?

Hi Lorno,

FeedbackPanel f = new FeedbackPanel("feedback"){
@Override
protected void onDetach() {

I have a form with a large number of textfields I want to validate for

I'm using an AjaxSubmitLink to submit my form.

To avoid displaying multiple error messages when multiple textfields fail
validation, I figure I could just delete all FeedbackMessages generated
during form validation, and then register my own FeedbackMessage.
However, it seems a thing of impossibility to delete (or mark as rendered)
existing FeedbackMessages.

I'm trying to do this in an AjaxSubmitLink's onError() method like this:

FeedbackCollector collector = new FeedbackCollector(form);
for (FeedbackMessage fm : collector.collect()) {
fm.markRendered();
}

But that doesn't do the trick. The feeback messages are found, but marking
them as rendered doesn't prevent them from being displayed.
I also tried collector.collect().clear() but that also doesn't work.

I also tried to do the same thing by overriding the form's onValidate()
method and deleting the messages right after validation, but that also
doesn't work.

How to get rid off these damn things?  :)

Thanks!

Hi Sven,

At the end of the table is a ButtomToolBar calculating sums of all rows.
(the Spinner is for changing amounts / prices for an item in the rows)

How can I refresh a single row? This would help a bit (than, later, I

Hi both,
ticket opened and quickstart attached.

https://issues.apache.org/jira/browse/WICKET-6041

Concerning reuseing components.
Yes, the clearInput() works, but the refreshed components, does not know 
anything about another component, which changes something.
So, I got a dependency on behavior-semantic from one component to the

Yes, wickets event bus can help here... but I currently vote for Martin

The outer form is not processed, because we don't want validation errors
to appear. #inputChanged() is called, so that on a possible render of
the whole page the input of the user is preserved.

I'm shocked ;)

Yes, and it comes with a price. In most cases it's not necessary to
include a form in panels - generally I would advice against it:
- because "it's not supported in HTML"
- again, it comes with a price (see above)

The problem I see is that Wicket treats #inputChanged() differently than
all other Form processing methods (like #validate(), #on[In]Valid(),
#updateModel()).
When a nested form is submitted Wicket calls the processing methods only
for the nested form.
I don't see a reason why #inputChanged() should be an exception.




It's rather unusual to have to formComponents for the same model on a
single page.

IMHO Patrick shouldn't use nested forms in the first place, I consider
them an advanced feature.



Advanced or not, it is very common to reuse components in Wicket.
So a Panel with a Form could appear as a nested anywhere. That is the
main
reason to support nested forms.

the user. So if your #onSubmit() logic in the nested form / submitter
repaints the form components in the root/parent form then their data
would
be lost and the user will have to re-type it again.

It seems in both cases the application developer will have to do
something:
1) either clear the input manually (as now)
2) or update it manually when needed (by calling #inputChanged()
only on
the FormComponents in the rootForm).

IMO the current behavior is wrong.

Please create a bug with a quickstart.

Wicket clears the rawInput

at org.apache.wicket.markup.html.form.FormComponent#valid().
FormComponent#valid() is called if the validation and conversion pass
successfully.
You can put a breakpoint and see what happens.

Re: Quetsion to nesting Forms and reflecting states of FormComponents after ajax refreshs

[Patrick Davids]

Hi Sven

> so you have two components using the same model? Interesting.
I didn't mentioned the details in my previous mail to reduce the 
description of the case.


Yes, its a shared model, because Form B is contained in a dialog.
And Form A comes from the Wizard (internal / needed for step transitions).

The dialog submits, closes and should refresh the underlying components 
on page.
Due to the structure of the page, I'm not able to put the dialog outside 
the wizard. Thats why I have the situation with nested form.


>choice1.clearInput();
Ok, I will try this.

setDefaultModelObject() and IModelComparator

[Patrick Davids]

Hi wicket pros,
could someone please give some further details about the default 
implementation of IModelComparator of Component doing an a.equals(b) of 
the both model-objects (old.equals(new))?


I often run into this issue when calling setDefaultModelObject(), 
because my expectation is having the new model-object, not the old one.

In (possibly) 99% percent of my use-cases I expect this behavior.

(Especially, when using own equals implementations in model-objects, 
which are not checking for members and changes)


Whats the main reason for this equals check?
Why not using an IModelComparator.ALWAYS_FALSE as default implementation?

Thanx in advance for feedback!

Re: Components/Behaviour execution order

[Patrick Davids]

Hi Col.,
sometimes I try to cheat by using onBeforeRender() in such cases to 
'fake' an order, because its called after onConfigure().

But this has some restrictions concerning visibility issues of components.
But in simple dependencies this sometimes works for me.

I think somewhere in wickets jira is an issue for a similar problem, to 
feature defining a kind of order of behaviors.

Unfort. I'm not able to find it right away.

Wicketeers,

This question is to do with lifecycle execution order - it's not a bug as such, 
just a usage question - I hope you can help.

I have component X with an AjaxFormComponentUpdatingBehavior, that triggers 
updates in Components Y and Z by adding to target.

Y has a generic Behaviour that updates it's data. Z needs to hide or show 
itself depending on Y's data state.

Y needs to use that generic Behaviour, as it's complex, does loads of stuff and 
is used throughout the system - so I can't change this.

Originally, in Z's onConfigure() we set the setVisible() depending on Y's 
state. But that doesn't work as Z's onConfigure() executes after Y's Behaviours 
onConfigure(). Which is just the way Component.configure() works. Which is fair 
enough.

So, I figured if Behaviours execute after onConfigure, I simply put the 
setVisible() code into a Behaviour on Z, and bingo!

Only Y's Behaviour always executes first. Always. Even if I create it second, 
even if I add Z to their parent container before Y. I can't work out how to 
affect the order of Components/Behaviour execution.

Note - I did extend the Y's Behaviour to update Z, but as Z has already 
completed its cycle, the state didn't actually update.

Can anyone help?

Col.

Re: Client side javascript listeners / HeaderItems / OnDomReadyHeaderItem

[Patrick Davids]

Hi Andrea,
thanx for your feedback...

Currently I'm researching more into AbstractDefaultAjaxBehaviors.

My javascript which should be executed with priority is an ajax-call.
So, it can be handled by Wicket itself.

I've seen the default event of an AbstractDefaultAjaxBehavior is a 
'ondomready', so that fits my needs.
Also IAjaxCallListeners are looking very good to me, to have the 
listener-feature.


Right now I'm facing the problem, how I can force my behavior beeing a 
singleton on page, but appling many IAjaxCallListeners to the 
updateAjaxAttributes() to support a list of success-handlers.

Have considered yet to use resource dependencies. You might create a
resource specifying which resource it depends on must be rendered first.
Than you can render it in your custom behavior. See chapter '16.6
Resource dependencies' of user guide.


This javascript-code should also applied to the page only once,
independently how often the behavior is added to my different
components on page.

I also need some sort of subscription code on javascript-side to get
notified.


To avoid multiple rendering of the same header item, class HeaderItem
uses method getRenderTokens to check if the item has already been
rendered. So if your heder item doesn't change (for example, the
javascript code is always the same) it won't be rendered more than once.


I already have some ideas to implement this, but would like to ask for
framework-features or other inspirations, best practices or ideas, first.

Re: FormComponentPanel and propagating model value to components

[Patrick Davids]

Hi,
quite unusal to me using a behavior to set a model.

Why dont you delegate to your inner textfiled by implementing an own 
setXYZModel()-method?


Or bind your inner textfield direct by providing a particular model in 
your Constructor of your custom MyFormComponentPanel?

And no onInitialize()-method...

public class MyFormComponentPanel extends FormComponentPanel {
  public MyFormComponentPanel(IModel myModel){
add(new TextField("id", myModel));
  }
}
(add generics if needed)

Re: AjaxRequests and middle mouse-clicks on links and buttons

[Patrick Davids]

Hi Martin,
I missed something.

We have a kind of own LinkComponent class here and someone in our team 
implemented an AjaxFallbackLink in the upper class hierarhcy, so 
currently we have a AjaxFallbackLink case here.

I didnt know that.

Thats the reason why I have a null AjaxRequestTarget.
Sorry, for giving a wrong hint here...

I removed the AjaxFallbackLink.

Now, the browser opens a new tab, with just having "javascript:;" as url.
(This also avoids the NPE issue mentioned in my previous mail.)

So, my question is reducing now to (and is not really wicket related 
anymore):

What the best practise to prevent a middle mouse click?

Browsers often features the middle mouse button to open a link or button

This is quite browser-specific, so I'm looking for the most independent

Clicking the middle mouse on a ajaxified Link or Button, the browser opens
a new tab and starts a usual request cycle.

This leads into wicket call e.g.
onClick(AjaxRequestTarget target)
but then the target parameter is null.
(I cannot use AjaxFallbackLinks in my case)

I'm able to handle this NPEs by implementing null-checks on every ajax
link.
Hmm... not the perfect solution.

So, I could try to prevent middle mouse clicks by a global javascript on
all pages.
I've seen several scripts, and here also it seems to be very
browser-specific (mousewheel, or not... event.which seem to differ and
so...).
Also, not my favorite solution, yet.

Then I thought about wicket solution. Is there any possible way?
I know about a IComponentOnConfigureListener, which can be used to have to
implement an application-wide onConfigure() for any component in page
hierarchy.
Is there something siilar e.g. IComponentOnAjaxRequestListener?
So I could implement some code there, checking for null and stop any
further code-calls on ajaxified wicket components, to avoid running into
NPEs in later code?

All these are my thoughts for now.

Thanx a lot for feedback...

AjaxRequests and middle mouse-clicks on links and buttons

[Patrick Davids]

Hi all,
I have a problem here, I would like to ask you for feedback.

I am not sure, if its more a jquery/js / wicket issue, so thanx in 
advance for any brainstorming and hints.


Browsers often features the middle mouse button to open a link or button 
in a new tab.
This is quite browser-specific, so I'm looking for the most independent 
solution.


Clicking the middle mouse on a ajaxified Link or Button, the browser 
opens a new tab and starts a usual request cycle.


This leads into wicket call e.g.
onClick(AjaxRequestTarget target)
but then the target parameter is null.
(I cannot use AjaxFallbackLinks in my case)

I'm able to handle this NPEs by implementing null-checks on every ajax link.
Hmm... not the perfect solution.

all pages.

Re: Wicket in web-fragments environment

[Patrick Davids]

Hi Martin,
while creating the quickstart the problem disappeared.
Its working.

I figured out, I had some wrong configurations in my m2e eclipse project 
specific settings while migration my project structure to web-fragments 
structure.
Due to that my classpatch settings were wrong and packaging of jars were 
incorrect. ;-)

Re: DataTable generics vs. IColumn generics

[Patrick Davids]

Hi Sven,
I did already implement it this way... and its working.

But my team members asked (more the client developers point of view), 
why the column-class itself is not a generic of Location, like this.


public class LocationColumn extends PropertyColumn {
...
}

At the current implementation they need to do
cols.add(new LocationColum(...));
instead of just
cols.add(new LocationColum(...));

Thats why I "forwarded" the question here, because I studied a bit the 
Column-Hierarchie code and also wondered about this strength coupling 
between T of ICellPopulator and T of rowModel and T of DataTable.



I suppose my team members see the PropertyColumn more like the usage of 
a PropertModel.
The generic of a PropertyModel is the type, which is returned by the 
expression.
The generic of a PropertyColumn is the DataTables generic / rowModel 
generic, not what its expression retrieves/returns/displays.


I think thats it...

As more as I think about this issue, maybe this could be a nice feature 
of PropertyColums.
Not to have a too strength coupling of what the column displays in the 
cell and what the data table shows.


kind regards
Patrick

Hi Patrick,

you can let your column implementation be generic:

  public LocationColumn(String expressionToLocation){
  super(Model.of("Location"), expressionToLocation);
  }

  @Override
  public void populateItem(Item> cellItem,
String componentId, IModel rowModel) {
  cellItem.add(new Label(componentId, new

What do you need more?

A column is responsible to provide a cell component for a row: For

Your LocationColumn should extend PropertyColumn:

 public class LocationColumn extends PropertyColumn{

 public LocationColumn(String expressionToLocation){

 }

 @Override
 public void populateItem(Item> cellItem,
String componentId, IModel rowModel) {

As I understand its the type of object shown by the table rows.

Reading the javadoc of AbstractColumn it says T (if I understand
correct), its the type of object shown by the cell itself.

But DataTable and its internal list of columns are bound together.
T of both must be the same...

I tried to implement something like this, and here I get problems.


List> cols = new ArrayList<>();
cols.add(new PropertyColumn(Model.of("Name"), "name"));
(compiler error)
cols.add(new LocationColumn("location"));
(compiler error)

new DataTable("id", cols, new
ListDataProvider(), 50);


public class LocationColumn extends PropertyColumn{

public LocationColumn(String expressionToLocation){

  @Override
public void populateItem(Item> cellItem,
String componentId, IModel rowModel) {
cellItem.add(new Label(componentId, new
LocationFormatModel(rowModel, Model.of(Session.get().getLocale();
}
}

Also the Generic of ICellPopulator is bound to T of column.

I always thought it could be possible to implement sub-class columns
to allow special renderings of table-cells.

But how can I achieve this, if also ICellPopulator is bound to T of
the rowModel?

But how can I achieve this, if also ICellPopulator is bound to T of
the rowModel?

kind regards

DataTable generics vs. IColumn generics

[Patrick Davids]

Hi all,
whats the meaning of generic T on DataTables vs T of IColumn and T of 
ICellPopulator?


As I understand its the type of object shown by the table rows.

Reading the javadoc of AbstractColumn it says T (if I understand 
correct), its the type of object shown by the cell itself.


But DataTable and its internal list of columns are bound together.
T of both must be the same...

I tried to implement something like this, and here I get problems.


List> cols = new ArrayList<>();
cols.add(new PropertyColumn(Model.of("Name"), "name"));
(compiler error)
cols.add(new LocationColumn("location"));
(compiler error)

new DataTable("id", cols, new ListDataProvider(), 50);


public class LocationColumn extends PropertyColumn{

public LocationColumn(String expressionToLocation){
super(Model.of("Location"), expressionToLocation);
}

@Override
	public void populateItem(Item> cellItem, 
String componentId, IModel rowModel) {
		cellItem.add(new Label(componentId, new LocationFormatModel(rowModel, 
Model.of(Session.get().getLocale();

}
}

Also the Generic of ICellPopulator is bound to T of column.

I always thought it could be possible to implement sub-class columns to 
allow special renderings of table-cells.


But how can I achieve this, if also ICellPopulator is bound to T of the 
rowModel?


kind regards
Patrick

Ok, done, WICKET-5788.

Thanx a lot...

I don't see anything in FormComponentFeedbackBorder code that consumes the
feedback message, i.e. marks it as rendered.
Please create a quickstart and attach it to a ticket in JIRA and we will
take a look.

Re: FormComponentFeedbackBorder / missing message display / Bug or Feature?

[Patrick Davids]

Yes, FormComponentFeedbackBorder itself just shows an asterisk.

So, ok, my question was still unclear. ;-)
Is it a feature or a bug, that a FormComponentFeedbackBorder surpresses 
the messages of its child formcomponent, which possibly could be shown 
by a FeedbackPanel somewhere else in the upper component hierarchy?

Well, according to
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/markup/html/form/validation/FormComponentFeedbackBorder.html
this border is supposed to show only a red asterisk in case the form
component is invalid. Nothing more. So it is by design.

My error message is not displayed, the asterisk is working.
I would expect it is displayed as the asterisk is displayed as well.

Re: form submit / parameters sometimes missing

[Patrick Davids]

Huh, good idea... I didn't think about that.

Ok, but I dont always miss my last parameters.
I also miss randomly in the middle. So, its not a case of truncation at 
the end.

And its POST, not GET.
Shouldnt be a problem...

form submit / parameters sometimes missing

[Patrick Davids]

Hi all,
I have a strange behavior when submitting a form via Ajax.
Sometimes some form fields are just missing.

As I can see Wicket serializes the form and posts data to the server.
Using FireBug I had a look at the posted data.

The data looks like this (see below). The second post request is ok, the 
first one misses some parameters. In this exmaple its di35, di36, di37.

I am not able to reproduce this savely for e.g. a fix set of parameters.
It's just random.

Can anyone help? I am out of ideas...
Thanx a lot and best regards
Patrick

[SOLVED] Re: PropertyModel / PropertyResolver / Map or List access

[Patrick Davids]

Hi Sven, Hi Paul,
thanx, now its working.

I thought the PropertyModel/PropertyResolver will unpack the 
model-object itself, so there is no need to adress getObject by ".object".
Maybe a small note in javadoc could help others not running into this issue.

So...
All ways (mentioned in javadoc) are working, tested:
(@Sven: I think you had some typos in your mail, so I will repeat my 
working tests)

new PropertyModel(MyPage.this, "list.object[1].anyProperty")
new PropertyModel(MyPage.this, "list.object.1.anyProperty")

new PropertyModel(list, "[1].anyProperty")
new PropertyModel(list, "1.anyProperty")

as well, navigation further, such an expression is working, too.
new PropertyModel(list, "1.anyProperty[any-string-key]")


Thanx for help... best regards
Patrick
P.s.
Short question for string-key-access on maps.
The syntax is quite equal to associative arrays in javascript.
I like the way it is in wicket, no need paying attention for additional 
quotation marks, and its ok for me, but shouldnt it also support
new PropertyModel(list, "1.anyProperty['any-string-key']")?

Re: PropertyModel / PropertyResolver / Map or List access

[Patrick Davids]

Hi Paul,
v6.17.0.

Maybe, I made a too reduced example.
My property navigates further... its more like this: 
"list[1].anyProperty[key]"

Is such a combination allowed?

PropertyModel / PropertyResolver / Map or List access

[Patrick Davids]

Hi all,

the javadoc of PropertyResolver says, map or list access is possible via 
keys or index.
Accessing an map via key is no problem, but I dont get it working for 
lists and index.

for instance:

MyPage extends Page{

   private IModel> list;

   public MyPage(IModel> list){
 super();
 this.list = list;

add(new Label("mylabel", new PropertyModel(MyPage.this, 
"list[1].anyProperty")));

   }

}

ends up in a Exception like this:
Last cause: No get method defined for class: class MyPage$1 expression: 1

I also made a try with "list.1.anyProperty".
Not working...

Any ideas?

best regards
Patrick

FeedbackPanel / just showing one error message / missing messages

[Patrick Davids]

Hi all,
I'm struggling around with a feedback panel.

What I would like to implement is a single global feedback panel in the 
top hierarchy of my page inheritence.

Its a sort of fallback-panel. If no other feedback panel catches the 
messages, it should display them, so its a FencedFeedback. A form or 
other component can have an own feedback panel with the component as a 
fence.

This global feedback panel should display only one single message.
Independent of how many e.g. form validation errors occur.
So its configured setMaxMessages(1).

To avoid displaying all other messages in sequence as long the user 
reloads the page, I have implemented a FeedbackCollector marking all of 
them rendered (onDetach()).

This all works quite good in the past.
But just one page, I have implemented once, does not show any messages 
at all by entering the page.

And I really really dont know why.

Also Session.get().error("my error message") does not work.

It seems to me, onDetach() is called earlier on this page, as on other 
pages, so my markRendered() of the FeedbackCollector is executed to 
early, but I am not sure.

Does anyone have an hint to me, what can force an early detach()?
Or what can force a cleanup of feedback messages?
Where should I put a breakpoint to have a deeper look?

Really thanx for help!

kind regards
Patrick

Yes, I also think so, but unfortunately currently I'm not able to

It is -somehow- the way you described. I think... hmm... but not very

Are markup modifications handled different by onBeforeRender() / add() 
compared to onConfigure() / addOrReplace()?

Or do I also have to use addOrReplace() in onBeforeRender()?

Re: alternative solution for addOrReplace()?

[Patrick Davids]

Hi Andrea,
this is the code (a bit pseudo-like...) I am quite sure it is not the 
way it should be and full of wicket anti-patterns. But still exists 
since my first wicket experiences 2 years ago. ;-)


This panel gets rendered via RefreshingView about 30 times.

public ElementPanel(String id, IModel 
elementState){  
super(id, elementState);

container = new WebMarkupContainer("innerElementContainer", 
elementState){
private static final long serialVersionUID = 1L;

@Override
protected void onConfigure() {
super.onConfigure();

ElementState s = (ElementState)getDefaultModelObject();

if(s instanceof DefaultState){

container.addOrReplace(new 
DefaultStatePanel(REPLACE_CONTAINER_ID, s));

}else if(s instanceof SpecialState){

container.addOrReplace(new 
SpecialStatePanel(REPLACE_CONTAINER_ID, s));

}else if(s instanceof AnotherSpecialState){

container.addOrReplace(new 
AnotherSpecialStatePanel(REPLACE_CONTAINER_ID, s));

...

}else{
String error = "No panel registered for class 
"+getDefaultModelObject().getClass().getSimpleName();
container.addOrReplace(new 
Label(REPLACE_CONTAINER_ID, error));
error(error);
}
}
add(container);
}

Re: alternative solution for addOrReplace()?

[Patrick Davids]

Hi Paul,
thanx for replying.

Oh, I use Ajax very heavily in this case. Thats why I said: "the panel 
works quite good for ajax rendering and refreshing use-cases"

Hmm... ok... I think I missed some details. I try to explain.

My page contains two sections seperated from each other.
A kind of data-entry and a kind of displaying the results.

The section which displays the results is a quite complicated panel, 
having an RefreshingView for about 30 (I will name them) sub-panels.

These sub-panels addOrReplace() an inner container while rendering itself.
And the replacement depends on my model object type.

So, my sub-panel class has a hugh knowledge about how to render the results.

On entering some data on the data-entry section I refresh the whole 
panel in the display section with all its sub-panels using Ajax. And 
this works great.
Some of the sub-panels also rerender/refresh own there own, by listening 
to events etc pepe. All this behaviours are working very well.

The only disadvantage is, using addOrReplace(), I have a heavy 
detaching/attaching situation and a performance problem.

So, the best solution for now would be, keeping my panel implementation 
as it is, but just having my models detached only once, not for iteration.

And here I dont have any idea how to solve that... :-/

thanx and kind regards

alternative solution for addOrReplace()?

[Patrick Davids]

Hi all,
I have a panel, which renders a inner markupcontainer (different panels 
for different ways of displaying my model object) depending on its model 
objects type.

I do this by addOrReplace() the inner panel in an onConfigure() having 
an "if instanceof"; and it also iterates over a list...

I'm not sure, if it is a good solution (I dont like the instanceof 
approach), but the panel works quite good for ajax rendering and 
refreshing use-cases.

But, the addOrReplace() has one big disadvantage.
It forces to detach the model on each iteration, so on each iteration I 
get a database access to retrieve it again.

Is there anyway to keep the model attached until the entire request 
cycle is finished?


Or should I try to find complete other solution for this kind of "high 
dynamic iterating panel"?
Is it better to use e.g. Fragments to display a model object in 
different ways depending on its state?

Please give some inspirations... I ran out of ideas. Help!

kind regards :-)

Re: How to init a Wizard with a particular step?

[Patrick Davids]

Hi Sebastien,
thanx, I have seen the DynamicWizardModel.

Its not exactly, what I need... will help for other reasons, but does 
not help not to unpack and evaluate my step while constructing.

My current implementation (I gave setActiveStep() a new chance) uses an 
onConfigure() of my Wizard calling getWizardModel().setActiveStep(...).

So, it also works with an usual WizardModel (dont know, what I made 
wrong some weeks ago).
I'm thinking about to keep this way...

How to init a Wizard with a particular step?

[Patrick Davids]

Hi all,
what I have here is an persistent workflow and I use a wizard to 
visualize this workflow.

On entering my page I wanna push the wizard into a specific step 
depending on my persistent workflow state/(step).

Until now I only was able to achieve this, by manually calling 
wizardModel.next(); as many times I need to reach my particular active step.

(I will give a new try for calling setActiveStep(), but as far as I 
remember I wasnt able todo this, Not sure, why...
Anyway...)
My main reason, I dont want to do it this way is, I have to unpack my 
model-object on construction-time and I have to implement a kind of "if, 
else, if else..." and I have to do this after wizard.init(wizardModel) 
because the wizard resets itself. So I have to pay attention for 
call-sequence etc. First init(), than next(), next(), next()...

Is there any better way to achieve this?
Maybe, I just dont see the wood for the trees...
An override of "amITheActiveStep()"-method of WizardStep evaluated by 
the wizard to show an active step depending on conditions?

Thanx for feedback

Re: DropDownChoice closes on target.add(...)

[Patrick Davids]

Hi Rune,
for me it looks like the feature of updating parts of your 
UploadFormPanel by using a timer should be a behavior of your 
UploadFormPanel itself.

Put it inside, and you have access the particular container to refresh. 
No need to refresh the whole panel from outside, which side-affects your 
dropdown choice and clicks etc.

kind regards

[SOLVED] Re: StringResourceModel with a defaultValue as model

[Patrick Davids]

Yes, already implemented this way. :-)
Added a todo now, waiting for wicket7 to improve it.
Thanx for the hint anyway...

Re: StringResourceModel with a defaultValue as model

[Patrick Davids]

Hi François,
what I try to do is a bit different... I would like to provide a default 
per component sub-class, before wicket cascades the property files up to 
application.properties.

Something like this:
add(new Label("", new StringResourceModel("key.${someInfoFromBean}", 
Component.this, Model.of(anyBean), new 
StringResourceModel("key.default", Component.this)));

Hi Martin,
ok, this will solve my problem, next.

StringResourceModel with a defaultValue as model

[Patrick Davids]

Hi all,
is there any way to implement a StringResourceModel which allows to give 
a defaultValue as model?

First I tried to override getDefaultModelAsString() of Label. (is final)
Than I tried to implement an extending 
ModeledDefaultValueStringResourceModel, catching a 
MissingResourceException on getObject() or load() and retrieving my own 
Model defaultValue, but everthing is final here, too.

So, Im not able to achieve this, right now.

I would like to do this, because I have a dynamic way of giving buttons 
a label depending of my Wizard-subclass (have my own 
SpecialWizardButtonBar).

And if a button label is not availabe I want to fallback somewhere, but 
the default cannot be a StringResourceModel.

Can someone help? Or is this a feature request and have to open a ticket?

kind regards, nice weekend
Patrick

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

[Patrick Davids]

Hi Colin,
and thanx to all responders...

Ok, I think I got it... somehow... ;-)

Got a new question then...
A RefreshingView, due to its method getItemModels(), also acts as a 
'Model Factory' for me... hmm...

Ähm, so, does anyone ever created a RefreshingView with a default model?
new RefreshingView("id", any_other_model_than_a_car?){
protected Iterator>getItemModels(){

}
}

Maybe, my first question relates to that.
But I am not sure... the RefreshingView is still a bit confusing to me...

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

[Patrick Davids]

Hi all,

what I often think about, and I cannot really say is; when to use Model 
or DataProvider as data providing object for components they repeat some 
thing?

Javadoc says, DataProvider are (good) for DataViews.
Hmm... ok, and they allow easer iterating (first index, count).

I also can achieve this by using a LoadableDetachableModel> 
combined with a ModelIteratorAdapater.

Both have detaching logic... both featuring extension, both have a sort 
of "load"-method (getObject() vs. getData()).

Sometimes I think, they are so similar to each other... where is the key 
difference?

Would be cool if some of yours just reply his "two cents" of daily 
programming experience... so I can get some new point of views.

When do you use DataProvider or Model>?
Did you experienced the same, not to exactly know which one you will use 
for your new page/panel/component?
And often think about pro and cons using it with RepeatingViews? And 
later on, you see... "I could have used both... hmm..."

thanx a lot for feedback and kind regards
Patrick

problem with resource lookup for css files

[Patrick Davids]

Hi all,
I have problems with resource look up for styles css... and I dont know, 
what I am doing wrong.

Can someone have a look, please...

myPackage.
BasePage.java
BasePage.html
myCss.css
myCss.blue.css
myCss.orange.css

As far as I know, the resource lookup for all kind of resources is the same.

I set the style to my Session via
Session.get().setStyle("blue");

and I can see the correct style string while debugging.


I tried to include my css into the BasePage via

BasePage.html

   
 
   


and also via

BasePage.java:
@Override
public void renderHead(HtmlHeaderContainer container) {
   super.renderHead(container);
   IHeaderResponse response = container.getHeaderResponse();
   response.render(CssHeaderItem.forReference(new 
CssResourceReference(BasePage.class, "myCss.css", getLocale(), 
getStyle(), getVariation(;
}

Both ways always look up the normal myCss.css and not myCss.blue.css.
Whats wrong with my code?
Help please...

Thanx a lot.

Hi all,
I'm not sure, if I do something wrong, but I never get such a property

Is this way not possible?

properties file:
label=${dateOfCreation, date, dd.MM.yy}


This is working...

Code:
new StringResourceModel("label", this, null, new PropertyModel(model,

properties file:
label={0, date, dd.MM.yy}

Is there any reason?
Could be a nice feature... I think...

Hi Ernesto,

I read the url-member by script from an attribute, we prev. added via 
AttributeAppender.


This is how I execute my ajax call:
$.ajax({
url : url,
type : 'POST',
.
.
.
success: function(data, textStatus, 
jqXHR){
self.processAjaxResponse(data, 
textStatus, jqXHR, data, textStatus);
},
error: function() { alert("error"); }

});

Evaluating wickets ajax-response programatically

[Patrick Davids]

Hi all,

due to a very complex gui panel with many javascript we are using a 
quite pure AbstractAjaxBehavior.

I print out a callback url, I call it, and so on... and having an 
onRequest() what nearly does the same as AbstractAjaxDefaultBehaviors 
(just a bit different).
Its copy-paste, but I dont know how to solve it in a better way.

Everything looks good, so far...

BUT...
when I add some components to the AjaxRequestTarget, the client-side 
does not evaluate it.

So, I had another look at wicket javascripts and found a js method 
named, which is used on success:

self.processAjaxResponse(data, textStatus, jqXHR, data, textStatus);

"Hmm... should do what I want"...

So I put it in my manuall Ajax.Calling scripts as success function, but 
still nothing happens.


Is there any magic evaluating the ajax-responses?
Can someone give my an hint?

Thanx a lot

Re: jquery ui DatePicker

[Patrick Davids]

Hi Dirk,
have a look at http://jqueryui.com/datepicker/#date-formats
and
http://api.jqueryui.com/datepicker/#option-dateFormat
to change the javascript-side jquery date formatting pattern to 
4-letter-year.
(Pay attention, it is a bit different to java date patterns.)

To do so, you have to apply the jquery date pattern as an Option to your 
DatePicker instance on java-side.
Something like this:
new Options("dateFormat", Options.asString("dd.mm.")

kind regards

Re: Best practice for updating JPA object without persisting changes

[Patrick Davids]

Hi Chris,
does the Guice's PersistFilter really automatically find and re-attach 
the backed object in the request while leaving the in-place-edit situation?

I thought... as long as "nothing"/nobody finds and re-attach the backed 
object, your changes are "naturally" temporary and only stored on page 
cache.

I would expect, it should already work out-of-the-box... But I did not 
work with Guice's PersistFilter, yet. May I miss something...

Hi François,
unfortunately this does not have any affect.

Still have all messages in sequence on reloading.

Handling with Feedback Messages / setMaxMessages(1)-Problem / best practise

[Patrick Davids]

Hi all,
I would like to have a FeedbackPanel always showing only one error message.

As seen in FeedbackPanel code setMaxMessages() does this.
But it seems it does not clear the rest of messages after doing its job.

When I have put 3 error messages on a page, only the first one is shown.
This is what I want, but reloading the page, all other messages are 
shown in sequence as long as I reload the page and until all are processed.

Is setMaxMessage() not the recommended way for what I want to do?
How can I force a clear?

thanx in advance :-)

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

[Patrick Davids]

Hi all,
what is the best way to start a Wizard in a particular step?

I tried:
- to override onInit of WizardStep and setting this to activeStep, when 
the state is the right one, but init() of WizardModel always determines 
the next step after me (the current active), so this seems not to be a 
good way. I could set the prevoius, but this is quite faked.

- to implement a condition; state is determined correct, but than all 
buttons are deactive, hmm...

- manually setting setActiveStep() after init of WizardModel, but this 
needs to unpack model object to construction time to evaluate my state 
on my own (but it worked as expected).

Did I miss something? Or is the third implementation the best trade-off?

kind regards

question form-usage / setDefaultModelObject(...) vs. getDefaullModel().setObject(...)

[Patrick Davids]

Hi all,
I have a question concerning the difference between 
Component#setDefaultModelObject(final Object object) and 
getDefaultModel().setObject(object), like described in javadoc

/**
  * Sets the backing model object. Unlike 
getDefaultModel().setObject(object), this
  * method checks authorisation and model comparator, and invokes 
modelChanging and
  * modelChanged if the value really changes.
...


The default model comparator uses equals, to determine changes of the model.

My question is, why setDefaultModelObject checks that?

We often ran into problems when a form saves an new object, because in 
our programming model, we do not implement the persistence id into our 
equals, and when we write the onSubmit()-ed saved model into the form 
back, our model is not getting the "fresh" state (with id).
(for us, its still equal, and we want it like this, but next clicks or 
savings create duplicate entry errors on database side)

Yes, we can use form.getDefaultModel().setObject(object), but this often 
leads in bugs, because you easily forget it;  setDefaultModelObject() is 
such a standard.

My first thought, on finding the method setModelObject of the form 
itself, was: ah, this is the feature method, really changing the object, 
but on a second look

setModelObject() of the form also just delegates to 
component.setDefaultModelObject(), rather then 
getDefaultModel().setObject().

Could someone explain why is it like it is?
May I do not see the clue...

Is it really wanted by wickets way of usage, calling 
getDefaultModel().setObject(object) if someone want to change the model 
of a form without equal-checks?

kind regards
Patrick

Re: Wicket Wizzard Question / Custom Overview Bars

[Patrick Davids]

Hi Paul,
thanx a lot for your detailed answer. :-)
Helped much, but my primary question was, why the overviewbar is on the 
left hand side, not on the top.

Possibly the header is what I am looking for, showing the current step 
information(?).

But then, I still do not know, what the overviewbar was originally meant 
for.

Wicket Wizzard Question / Custom Overview Bars

[Patrick Davids]

Hi all,
did someone already noticed, a custom overriden overview-bar of wickets 
wizzard is displayed in a  left of the Step contents ?

I thought it would be on the top...

Or did I misunderstood the meaning of the overview bar?
Is it meant as kind of menu?!

Re-Usable Panel with RefreshingView

[Patrick Davids]

Hi all,
I would like to implement a reusable panel, containing a refreshing view.

The goal is to delegate the polulateItem(Item item) of the refreshing 
view to the outer client, e.g. the page which uses my panel.
(I force overriding using abstract method).

So far so good.

My problem now is:
My inner refreshing view must provide a webmarkup container, I must use 
to add my custom components from outside (populateItem(item){ 
item.add(myCUstomComponent) }).

Quite ok... but I need to know the inner id in the outer client (kind of 
LazyLoadingPanel), but I dont want having it in this way, providing my 
inner id to the outer "world".

What kind of Repeating/RefreshingView should I use?

I think, I need some sort of mixed Repeating&RefreshignView feature.

RepeatingView works with newChildId(), and can have outer markup (hope I 
understood right),but is not very refreshing.
RefreshingView works in a refreshing way, but must hold its own markup.

Can anyone give some inspiration and help for my reusable panel?

kind regards
Patrick

Re: Wicket DropDownChoice Question about Constructors and its Behavior

[Patrick Davids]

Hmm... ok,
does that mean, in forms I do not have to wrap my model(object) into a 
CompundPropertyModel, because DropDownList (or even all FormComponents?) 
automatically joins IComponentInheritedModel hierarchy?

So, as conclusion, by using a constuctor with an empty model (id, new 
Model(), List choices) a exclude my DropDownChoice from the hierarchy?

Wicket DropDownChoice Question about Constructors and its Behavior

[Patrick Davids]

Hi all,

since I'm working with Wicket I am a bit confused about the Constructors 
of DropDownChoice Class.

DropDownChoice provides Constructors without any Model or ModelObject.
e.g. (id, List choices)

This is logical in an use-case, for instance, having just a page with a 
SelectBox and my first click is about to choose something.
And I may do not have any "parent" model object of the page, so I did 
not bind my DropDownChoice by PropertyModel expressions.

So, in such cases...

Why Wicket always complaints about "try to set ModelObject of null model"?

Yes, I explicitly decided to use DropDownChoice without a model.
Since nothing is chosen, the model object of the DropDownChoice is null.
The behavior I expect is, the model object is the chosen option (object) 
after selecting one.

But it seems, it does not work like this.

Can someone please "light" me. :-)

kind regards
Patrick

SOLVED / Re: How to make an own panel work like an e.g. TextField / joining the model hierarchy of page/form

Hi Martin,
thanx, its working, now.

I had some additional convenience constructors in my panel with empty

Just having one, only with an id, made it work.

Re: How to make an own panel work like an e.g. TextField / joining the model hierarchy of page/form

[Patrick Davids]

Hi Martin,
concerning the IComponentInheritedModel I did not not try anything in my 
panel since yet, because I suppose it should work from the scratch, when 
a manually wrap the ModelObject on form level into CompundPropertyModel.

As I can see CompoundPropertyModel is an IComponentInheritedModel, and I 
understand, why this works.

Form f = new Form("anyid", new CompoundPropertyModel(PersonObject));
f.add(new TextField("personName"));



My question focused more on, what I should implement in 
MyOwnTextFieldPanel("personName") to act the same way like an usual 
textfield, not what I have to do on the parent component/form.
An ususal TextField "joins" the Form and its inner CompundPropertyModel 
(Handling) in a magic way, and I would like to have the same feature for 
MyOwnTextField.

How to make an own panel work like an e.g. TextField / joining the model hierarchy of page/form

[Patrick Davids]

Hi all,
I implemented a "TextField-Panel".
Its kind of FormComponentPanel, but not really... do not have a 
convertInput() situation.
Just additional behaviors and some own l18n stuff...

Its already working fine, but what I always have to to is, getting the 
modelobject manually and forward into my form (model object), where it 
is used.

I would like to implement it in a way, behaving like CompundProperty 
modeled forms.

I read about an IComponentInheritance marker interface, but I do not 
know, how to use it.

Can some one help?

Wicket/JQuery internals advanced problem / LazyLoadedPanel with AjaxLink / AjaxLink on click not executed

[Patrick Davids]

Hi all,

I have a very special problem with ajax lazy loaded panels, which 
contains ajax links.

Problem: AjaxLink does not execute "onclick". Does not reach server / no 
client-side execution in browser occurs.

What I investigated until now:
- client-side script evaluation of lazy loading panel works.

I can see script like this:
{Wicket.Ajax.ajax({"u":"./page?6-8.IBehaviorListener.VERY_LONG_ID","e":"click","c":"edtc5"});})();

- I stepped into the evaluated javascript code Wicket.Ajax.ajax(attrb) 
with firebug.

- inside a jquerys each() iterates over all elements, and adds onclick 
event handling to the particular element/a-link ("c":"edtc5" of script 
above).

see:
wicket-ajax-jquery-ver-xyz.js
line: 1800
jQuery.each(attrs.e, function (idx, evt) {
  Wicket.Event.add(attrs.c, evt, function (jqEvent, data) {
var call = new Wicket.Ajax.Call();
 var attributes = jQuery.extend({}, attrs);
 attributes.event = Wicket.Event.fix(jqEvent);
...


So far so good...
At this point it gets to deep for me. :-/


Can any wicket pro please help, why the onclick (I think its binded 
correctly) of my link does not get fired to let execute the ajax request?


I already made a quickstart with different lazyloaded panels, and all 
ajaxlinks are working fine.

kind regards

Re: conditional component / as singleton on page

[Patrick Davids]

Hi Sebastien, Hi Martin,
the dialog was just an example.

My question was more focused on a feature similar to the javascript or 
css resource "wicket feature".
Putting a resource only once into the page header no matter how many 
components "requested" to do that.

But on component level.

(I am in a case with a repeating view.)

conditional component / as singleton on page

[Patrick Davids]

Hi all,
does anyone have a best practice putting a component on a page (as 
singleton) independendly how many other components on that page "needs" it?

e.g. a global dialog, which can be used from different components.
Not to have 20 invisible dialogs aleady rendered and opened on request.

In out special to achieve this we do not want use page inheritence.
This component shouldn't be on page, if no other component needs it.

thanx for help...
kind regards

Hmm... "select", but is fired via jquery on client side, and I do the

setResponsePage does not work / on (own) ajax requests

[Patrick Davids]

Hi all,
I implemented a panel having its own AbstractAjaxBehavior.

I provided the callback url to my pagepanel, the ajax request works; 
everything seems fine.

Than I implemented an abstract method onSelect() to my panel to let an 
implementation do some custom thinks (the onRequest() of my internal 
behavior just delegates to abstract onSelect() of my panel)

My first test... simply doing a:

add(new MyPanel("foo"){
   public void onSelect(){
 setResponsePage(some where)
   }
)

but nothing happens...

Using AbstractAjaxDefaultBehavior overriding respond() and delegating to 
onSelect() does not work, too.

Do I have to do something special, to behave like an e.g. AjaxLink?!?
setResponsePage() is working there...

kind regards
Patrick

Need help with FeedbackMessageFilter

[Patrick Davids]

Hi all,

I have a FeedbackPanel in my page and a FeedbackPanel in the form of my 
page.

Both feedback panels show feedback messages of the form.

I tried formfeedbackPanel.setFilter(new 
ComponentFeedbackMessageFilter(theForm)).

I tried formfeedbackPanel.setFilter(new 
ContainerFeedbackMessageFilter(theForm)).

But nothing works...
Thanx for help.

Re: Question / extracting models in constructors

[Patrick Davids]

Thank you. :-)
Interesting concept...

Unfortunately still have the question:
Why is it recommended not to extract a given model (1), if it is just 
needed to create another empty model (2) via a servicecall in a 
constructor (I do not hold a reference to model (1) as member in the 
page or component)?

And why should I explicitly not do an extract in a constructor?

I'm asking because our discussion always ends into "we have to extract 
it anyway, just somewhere else."

regards
Patrick

Question / extracting models in constructors

[Patrick Davids]

Hi together,

I'm in a discussion with my collegues about extracting models in 
constructors of components.

Best practices says: DONT, because of accidently holding references of 
extrated objects / out of mems / etc.

But, if we want to have a component containing a form is responsable to 
create its own emtpy model, if not created yet.

Is it ok, to extract a model "temporary"?

here an axample:

A person has an address.
An extra component panel with form fields for creating/editing addresses 
exists (nested forms pattern).
The AdressComponent gets a model of person.

In case of: person does not have an address, yet.

Is it allowed to extract the person model, to make a service call 
somewhere to let create an empty address object for this particular 
person and then setting the model object on my own?

We would like to have the knowledge about creation and saving addresses 
put toghether in the AddressComponent instead of having the knowledge 
about saving inside (onSubmit() of form), and the knowledge about 
creation outside the AddressComponent.

kind regards
Patrick

Re: Solved / Re: Need help setting visibility via AjaxFormChoiceComponentUpdatingBehavior

[Patrick Davids]

I read this article and my first approach was like

"If an outside component controls another’s visibility the best way is 
to override the controlling component’s onConfigure() and call 
controlled.setVisible()"

But this doesnt worked, because onConfigure() of my RadioChoice runs 
only once.

What I can do to force onConfigure() of RadioChoice again is, also 
adding it to the AjaxRequestTarget.

r.add(new AjaxFormChoiceComponentUpdatingBehavior(){
  @Override
  protected void onUpdate(AjaxRequestTarget target) {
->   target.add(r);
  target.add(wmc);
  }
  }

This works, too...

I am not sure now, whats the better way... *lol*

Determine "my" visibility in my onConfigure() by watching the state of 
the controller by myself, and adding only one object to the 
AjaxRequestTarget.

or

Let set the visibility of "me" by a controller and adding two objects to 
the AjaxRequestTarget, so the onConfigure() of the controller can do its 
visibility setting job.

Pull or Push?

regards
Patrick

Solved / Re: Need help setting visibility via AjaxFormChoiceComponentUpdatingBehavior

[Patrick Davids]

I am not sure what exactly was wrong.
Perhaps I had too much code with several active setVisibility...() XYZs 
code parts.

I started from the beginning and found the beautiest way for me, looking 
like this.

final RadioChoice r = new RadioChoice("id", 
Model.of(""), Arrays.asList(new String[{"visible","invisible"}));

r.setModelObject("visible");

final WebMarkupContainer wmc = new WebMarkupContainer("wmc"){
@Override
protected void onConfigure() {
if(r.getValue().equals("0")){
setVisibilityAllowed(true);
}
if(r.getValue().equals("1")){
setVisibilityAllowed(false);
}
}
wmc.setOutputMarkupPlaceholderTag(true);

r.add(new AjaxFormChoiceComponentUpdatingBehavior(){
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(wmc);
}
}
);



onConfigure() is always be executed, and can toggle the visibility.

AjaxFormChoiceComponentUpdatingBehavior.onUpdate() just pushes back the 
wmc, and due to onConfigure() of the wmc it determines its visibility 
depending on the new state of RadioCoice r.

kind regards
Patrick
