[Wicket-user] IComponentInstantiationListener problem
Hi,
I'm using IComponentInstantiationListener to add additional
functionality to my components. But in this listener I need to know the
model of the component to condition this functionality.
If we inspect the code, we can see that the listeners are called before
assigning the model to the component:
public Component(final String id, final IModel model)
{
setId(id);
getApplication().notifyComponentInstantiationListeners(this);
this.model = wrap(model);
final IDebugSettings debugSettings =
Application.get().getDebugSettings();
if (debugSettings.getComponentUseCheck())
{
setMetaData(CONSTRUCTED_AT_KEY, Strings.toString(this, new
MarkupException(
constructed)));
}
}
Are there any reason to do the notification in that moment?
Thanks

Re: [Wicket-user] IComponentInstantiationListener problem
I think I cannot use this solution.
The problem in that case is that the behavior is executed in another
moment, not in instantiation time of the component. And the children of
the component depend of this listener.
For this reason, the only moment where I can execute the functionality
is in the listener, when component is instantiated.
I've had this same issue when trying to build a component
instantiation listener for inspecting hibernate annotations. Since
the IComponentInstantiationListener interface doesn't have a hook for
onModelBinding, i've tried to use Behaviors instead. Can you try
something like this?
public MyComponentInstantiationListener implements
IComponentInstantiationListener {
public void onInstantiation(Component component) {
component.add(new MyBehavior());
}
}
public MyBehavior extends AbstractBehavior {
public void bind(Component component) {
super.bind(component);
//inspect the model of the component and do your crazy work here
}
}

Re: [Wicket-user] IComponentInstantiationListener problem
I know IComponentOnBeforeRenderListener, but I cannot use this
interface, because I need to condition
the instantiation of the children of my component, depending of the
functionality of the Listener.
And if I use IComponentOnBeforeRenderListener, the instantiation has
been finished when the interface
is called.
The best moment to use this functionality is in the
IComponentInstantiationListener... because any children
have been still instantiated.
There is now - since a few weeks - also
org.apache.wicket.application.IComponentOnBeforeRenderListener, which
may suit your needs better.
We (Teachscape) use it like:
public final class ValidationListener implements
IComponentOnBeforeRenderListener {
public void onBeforeRender(Component component) {
if (component instanceof FormComponent !component.hasBeenRendered()) {
// add validators
processComponent((FormComponent) component);
}
}
and in our application's init method:
addComponentOnBeforeRenderListener(new ValidationListener());

[Wicket-user] Problem adding css with ajax in Firefox
Hello,
I'm trying to load css files with ajax, but the problem is that the
rendering of the components are executed before the loading of the css
files.
This problem means that if I have to use styles in the component
updated, these styles are not executed, because when the component is
rendered,
the styles are not loaded yet.
This is a very simple example where the css file doesn't work correctly:
MyPage.java:
public class MyPage extends WebPage
{
private static final long serialVersionUID = 1L;
private Component panel = null;
public MyPage(final PageParameters parameters)
{
super();
panel = new Label(this,panel,panel);
panel.setOutputMarkupId(true);
AjaxLink link = new AjaxLink(this, link, new Model(link)){
@Override
public void onClick(AjaxRequestTarget target) {
panel = new MyPanel(TogglePanePage.this,panel);
panel.setOutputMarkupId(true);
panel.add(HeaderContributor.forCss(this.getClass(),
mycss.css));
target.addComponent(panel);
}
};
}
}
MyPage.html
html
body
h1Dialogs/h1
div style=padding:20px
h4Inline Accordeon/h4
div style=padding-left: 40px;
span wicket:id=panel/span
a wicket:id=linklink/a
/div
/div
/body
/html
MyPanel.java
public class MyPanel extends Panel {
public MyPanel(MarkupContainer parent, String id) {
super(parent, id);
}
private static final long serialVersionUID = 1L;
}
MyPanel.html
html
body
wicket:panel
scriptalert(loaded)/script
div class=testtest/div
/wicket:panel
/body
/html
mycss.css
body
{
background-color: red;
}
In the example, the javascript alert() is executed before the
background-color has been changed. And the background-color would have
to be changed before.
I think this is not a correct behavior, because with javascript files
work correcty. But javascript files call to the server to load the file
and css files don't call to the server.
Any suggestion?
Thanks

Re: [Wicket-user] Problem adding css with ajax in Firefox
The most important is not the example, the important is the concept. The
file is loaded after the rendering of the component.
Another example:
TogglePanePage.class
public class TogglePanePage extends WebPage
{
private static final long serialVersionUID = 1L;
private MyPanel panel = null;
public TogglePanePage(final PageParameters parameters)
{
super();
panel = new MyPanel(this,panel);
panel.setOutputMarkupId(true);
AjaxLink link = new AjaxLink(this, link, new Model(link)){
@Override
public void onClick(AjaxRequestTarget target) {
panel.get(mypanel2).setVisible(true);
target.addComponent(panel);
}
};
}
}
TogglePanePage.html
html
body
wicket:extend
h1Dialogs/h1
div style=padding:20px
h4Inline Accordeon/h4
div style=padding-left: 40px;
span wicket:id=panel/span
a wicket:id=linklink/a
/div
/div
/wicket:extend
/body
/html
MyPanel.java
public class MyPanel extends Panel {
public MyPanel(MarkupContainer parent, String id) {
super(parent, id);
new MyPanel2(this, mypanel2).setVisible(false);
}
MyPanel.html
wicket:panel
div wicket:id=mypanel2test/div
/wicket:panel
MyPanel2.java
public class MyPanel2 extends Panel {
public MyPanel2(MarkupContainer parent, String id) {
super(parent, id);
add(HeaderContributor.forCss(this.getClass(), mycss.css));
}
}
MyPanel2.html
wicket:panel
scriptalert(loaded)/script
/wicket:panel
mycss.css
body
{
background-color: red;
}
Thanks
This doesn't really make sense. You can't create panel in the onClick
handler without placing it anywhere in page. You can either create the
panel in advance (and hide it) or create another component and replace
it by the new panel panel.

[Wicket-user] Adding onload event in Ajax border
My problem is that I want to call to a javascript method after the
rendering of a page or after the rendering of the component with ajax.
Now I have a border and I want to add in the component an onload event.
For instance:
body onload=alert('test');
wicket:border
wicket:child/
/wicket:border
/body
The alert runs correctly if I use the border in the page. But if I
update the border
with ajax, the alert is not rendered.
Who can I do to add the alert in both cases?
Thanks

Re: [Wicket-user] Why add(IBehavior) is final?
In my case, I have created a TextField component, that is a panel that
contains internally a TextField wicket component. Now, if I add the
method addToField, the user will have two methods:
TextField.add(IBehavior behavior)
TextField.addToField(IBehavior behavior)
I think that this case will be more confused than if I have only one
method:
TextField.add(IBehavior behavior){
textField.add(behavior);
}
I don't want to add any behavior in the panel, I only want to add
behaviors in the field. Why do I have to create another method, that it
will be more confused for the user?
This is the same situation that when we use the IAlternateParent. We
add the component in a component, but the real parent is another...
I am definitely /not/ against removing final, but it is not going to
work (not in general that is).
Alberto's defense is that the user thinks he is working with a field,
while in reality he is working with a panel. I assume that Alberto is
using a panel because he wants some extra functionality around the
field, say a button or a link. Anyway, now the user adds some behavior,
say 'new SimpleAttributeModifier("style", "background-color: #d91")'.
Now in the described setup only the field will get the new background,
while the user probably also wanted to color the whitespace around it.
As a user I would find this pretty confusing.
In short: there is no way of hiding the fact that the component you are
offering to a user is a composite, if you also want the user to have
access to the inner components.
So my solution would be to either expose the inner field through a
getter, or write the addToField method that was discussed earlier.
Regards,
Erik.

I could definitively live with removing final there. And maybe some

[Wicket-user] How to configure a HeaderContributor
Hi,
I want to add a css file to a component, but this css can be defined by
the user. For example:
public class TabSet extends PanelString implements
IAlternateParentProvider{
private ResourceReference styleURI = new
ResourceReference(ManagerStyleSheetFiles.class, tabSet.css);
public TabSet(MarkupContainer parent, String id) {
super(parent, id,new ModelString());
add(HeaderContributor.forCss(styleURI));
Toolbar toolbar= new Toolbar(this, tabs);
}
}
and the user can do this:
TabSet tabSet = new TabSet(form, tabSet);
tabSet.setStyleURI(new
ResourceReference(ManagerStyleSheetFiles.class, main.css));
The problem is where or when can I add the HeaderContributor in the
tabset to use the correct css file?
Because if I add the HeaderContributor in the contructor, I cannot
change it later.
Any idea?
Thanks

Re: [Wicket-user] How to configure a HeaderContributor
Yes, but I don't know when I have to add the behavior.
In the internalOnAttach I cannot add the behavior, because I want to add
it only one time.
I need to add the behavior before of the first rendering and I need to
add it only one time...
Just add it later. As long as you add it before the component renders,
you're fine.

[Wicket-user] Why add(IBehavior) is final?
Hi,
I want to overwrite the add(IBehavior) method of the component, but this
method is final.
I want to use the same idea of AlternateParent when we add a new component.
I have a panel, and I want to add a behavior in the panel, but the
behavior is used in a field
component that is in the panel.
I don't want to say:
panel.get(myField).add(new MyBehavior());
I want to say:
panel.add(new MyBehavior());
and in the add() method of the panel say:
public Component add(final IBehavior behavior)
{
get(myField).add(behavior);
}
Any idea to implement this functionality?
Thanks

It would be a very good idea. ;)
we could make the protected final so that you can add your own method
that calls the validation methods you do want.

Re: [Wicket-user] Problem with FormBorder and not visible components (in trunk)
Hi Juergen Donnerstag
Thanks for you patience. ;)
The problem has been fixed with the changes that we have added to the
trunk.
Now I have another question.
In the example BoxBorderTextPage_7 we add a TextField in the FormBorder.
After that,
If I want to find this component into the FormBorder component, I cannot
find it.
public BoxBorderTestPage_7()
{
Border formBorder = new FormBorder(this, border);
TextField textfield = new TextFieldString(formBorder, name,
new PropertyModelString(
properties, name));
Component c = formBorder.get(name);
// Test setVisible on formBorders
textfield.setVisible(false);
new Link(this, link)
{
private static final long serialVersionUID = 1L;
@Override
public void onClick()
{
String p = ;
}
};
}
The line Component c = formBorder.get(name); has been added in the
example, and return null.
Is correct this result, or the get() method should return the TextField
component?
I extened BoxBorderTestPage_7 to click the link and to validate the
output of the second render as well. The problem should be fixed.

Hi Juergen Donnerstag,
The example BoxBorderTestPage_7 runs correctly because you only render
the page only one time. The problem is if
you have to reload the page again, because TextField has been removed in

doesn't find this component in the second rendering.
I don't know how to simulate the situation in a test case, but if you
check the example that I wrote,
you will see the problem:

Re: [Wicket-user] Problem with FormBorder and not visible components (in trunk)
Yes, now the ways to find the child into the border are the ways that
you say, but I think that the
way would have to be transparent, like when we add a new child:
TextField textfield = new TextFieldString(formBorder, name,
new PropertyModelString(
properties, name));
In that case, I really don't know where the textfield is added. Only
internally the textfield is added in the body container.
For the same reason, when I want to search a child, I don't have to know
where is exactly this child...
I think that in this case, I only have to know that the textfield has been
added in a formborder, and I have to go to search this field in the formBorder.
In this case, the get() method of the formBorder have to know internally where
is the
children, depending of the body container.
I think this is a good idea to implement for components that implements
IAlternateParent...
Because FormBorder puts a form _around_ the wicket:body tag, the
name component gets added to the body container. The body container
id is border.getId() + Body. Hence
get(border.form.borderBody.name) or
border.getBodyContainer().get(name) or
formBorder.get(borderBody.name)

Re: [Wicket-user] Problem with FormBorder and not visible components (in trunk)
Yes, this method can be used,
but imagine that I create my own FormBorder, that other people will use
to create different forms.
These developers can add content to this FormBorder, and they will add
this content in the FormBorder
component.
Border formBorder = new FormBorder(this, border);
TextField textfield = new TextFieldString(formBorder,name, new
PropertyModelString(properties, name));
These developers don't have to know that the components have been added
in the form component, because
they are adding the components in the FormBorder component. How the
FormBorder works internally is not
important for these developers. They only have to know that they are
adding components to the FormBorder.
For this reason, If they want to search the textfield component, they
only have to search this component
in the FormBorder component.
It's only an idea that would be nice to have in your framework, and
probably will be interesting for the
developers that they use this functionality. ;)

a couple of notes on wicket 2.0 in general.
because of constructor change and the need for IAlternateParentProvider you
can no longer assume that
Container c=new Container(...);
Label l=new Label(c);
l.getParent()==c
that is simply the nature of the beast. if you need to get a hold of l after
you added it to c later, then keep a reference, dont depend on the id.
same thing is with models because of the way they wrap each other
IModel model=getModel();
Labe l=new Label();
l.setModel(model);
you cannot depend on
model==l.getModel()
because if model was assignment aware it wouldve generated a wrapper of
itself in setModel() call.

not quite. Remember that in case of FormBorder you must call
Border.setBorderBodyContainer(parent). Hence, it is not completely
transparent.
In that case, I really don't know where the textfield is added.

You see the nasty point about this is that we would have to maintain
two parent per component. The real one and the user one.
Give me some time to think about it.

Re: [Wicket-user] Problem with FormBorder and not visible components (in trunk)
you have the the test case:
public class BoxBorderTestPage_3 extends WebPage
{
private static final long serialVersionUID = 1L;
private final ValueMap properties = new ValueMap();
/**
* Construct.
*
*
*/
public BoxBorderTestPage_3()
{
Border formBorder = new FormBorder(this, border);
new TextFieldString(formBorder, name, new
PropertyModelString(properties, name));
}
}
That runs correctly.
But if you change TextField component to setVisible(false):
TextField textfield = new TextFieldString(formBorder, name,
new PropertyModelString(properties, name));
textfield.setVisible(false);
Then the case has an error, because in the
DiffUtil.validatePage(document, this.getClass(), filename) the component
doesn't exists.
(Because has been removed by the page when it check if the autocomponent
contain not visible component to remove).
This is V2 svn trunk? Could you please create a test case (see
src/test) for me which makes is much easier to follow up. Thanks

Hi,
the problem is when I want to add in a FormBorder a component with
setVisible(false), because this component
is removed in the first rendering, and in the next rendering the
component is not found.
This is a simple example:
MyBorderPage.html
div wicket:id=border
label wicket:id=span
test
/label
/div
a wicket:id=linklink/a
MyBorderPage.java
FormBorder border = new FormBorder(this, border);
Label span = new Label(border, span,testt);
span.setVisible(false);
new Link(this, link){
@Override
public void onClick() {
String p =;
}
};
When I click the link, I have the error:
Unable to find component with id 'span' in [MarkupContainer
[Component id = auto-body, page = com.isencia.paging.wicket.MyBorderPage,
path = 8:border:myForm:auto-body.Border$BorderBody, isVisible = true,
isVersioned = true]].
Do you know any solution to solve this problem, or is a bug?
Thanks

[Wicket-user] IAlternateParentProvider method attributes
Hi, I'm using the IalternateParentProvider to manipulate the parent of the children of my component. But the problem is that I need information about the children in getAlternateParent method and I only have the childClass and the childId. Why the child component is not passed to the method? Are there any way to know what is the child? Thanks - Take Surveys. Earn Cash.

[Wicket-user] Problem with RepeatingView in trunk
Hi, In Wicket 1.2 I had this code: RepeatingView r = new RepeatingView(form); r.add(new Label(view,view)); r.add(new Label(create,create)); add(r); Now in trunk I have: RepeatingView r = new RepeatingView(form, toolbar); new Label(r, view,view); new Label(r, create,create); but this code doesn't run now. If I change the ids of the labels by numbers like: RepeatingView r = new RepeatingView(form, toolbar); new Label(r, 1,view); new Label(r, 2,create); then it works. But my problem is that I have predefined components with their specific ids and I cannot change these ids. Why doesn't it run as previous version? Are there another solution to use another kind of ids? Thanks - Take Surveys. Earn Cash.

[Wicket-user] Adding events to a form component
I would like to know if is possible to add different actions to the same
event
to a form component. For instance, I want to add two actions to the same
textfield, but from different places:
textField.add(new SimpleAttributeModifier(onchange,
alert(this.value);));
textField.add(new SimpleAttributeModifier(onchange,
alert('this.value');));
The problem is that the second attribute overwrites the first attribute.
Do you have implemented some functionality to do this?
Thanks
