Question about markup inheritance and page layouts
I was a little confused about page layouts and markup inheritance. I
was thinking that a I could take a piece of HTML markup and reuse that
component when I need to, and use it multiple times within page without
ever having to create the content.
I was not able to do this. What I have now, it seems I can only use
parent child inheritance with one sub-component.
Pseudo Code
BasePage.java:
public abstract class BasePage extends WebPage {
public BasePage(final PageParameters parameters) {
}
}
BasePage.html:
html
wicket:child /
/html
SomePage.java
public class SomePage extends BasePage {
public SomePage(final PageParameters parameters) {
}
}
SomePage.html:
wicket:extend
div
div wicket:id=myPanel/div
div wicket:id=myPanel1/div
/div
/wicket:extend
BasePanel.java
...
BasePanel.html
div
wicket:child /
/div
MyPanel1.java extends BasePanel
...
MyPane1l.html
wicket:extend
div
/div
/wicket:extend
Basically:
BasePage has child page - Some Page ... Some Page has child panels
BasePanel - My Panel and My Panel1
...
I don't get the output I would expect. It looks like the markup
inheritance stops at SomePage and doesn't recognize
the BasePanel HTML child code.
My intended goal is to avoid duplicating HTML content, what is the best
way to achieve that. Maybe I should use markup inheritance for the
panel instead of the page?

Newbie question anti-patterns and wicket, constructor component building
I am sorry, am just getting used to Wicket but I notice a lot of use of calling a lot of code in the constructor. Does it really matter? I mention it because this kind of style makes it difficult to test code because code in the constructor may fail and the object won't be created. Should I just create a method and call that method in the constructor?

Should I just create a method and call that method in the constructor? The constructor is supposed to construct the object. In Wicket, this also (typically) means constructing the component hierarchy. So, your constructor should be doing things like add(new FooPanel(foo, new SomeModel())); It should NOT be doing things like: ListFoo foos = SomeDao.loadAll(); new FooPanel(foo, foos); That's the kind of code I see newbs putting in their constructor all the time - and it should NOT be there. -- Jeremy Thomerson http://www.wickettraining.com - Well, the second version uses constructer injection.

Specific user/session properties and resources
I still want to use wicket message resource tags in my markup. But, I
need a system to load and reload resources property data for each page
and request.
Or maybe load properties per user session. Is this possible using
Wicket resource loader classes.
Ideally, it looks like I should use a collection of labels, but I have
code to use the wicket message tags. Can I have wicket messages
reloaded at each page/request?
This is what I am doing now, loading a property file on startup/init.

Dynamic Resources, Properties
I want to be able to use the StringResourceModel, but
I want to use a property string that is loaded when the page is
loaded.
Basically, I want to set a dynamic property object?
With this code below, how can I do this.
public class SomePanel extends BaseContentPanel {
private static final long serialVersionUID = 1L;
public SomePanel(String id) {
super(id);
add(new Label(weatherMessage, new
StringResourceModel(weather.message, this, null)));
}

Hierarchy mismatch with forms and hideable sections.
I am getting a hierarchy error message and the error makes sense, but how do you construct a form that also has hideable sections: This is what I had originally, a form and sub components. This works fine: Java: form = new Form(); panel.add(form); form.add(new TextField(t1)) form.add(new TextField(t2)) Html: form input wicket:id=t1 / input wicket:id=t2 / /form The above pseudo code works fine. Now I want to change to the following (html): Html: form input wicket:id=t1 / div wicket:id=hideableSectionDisabledInitially input wicket:id=t2 / /div /form ... What would I change in the java code so that the code is disaled initially, also such that the t2 text field is part of the form hierarchy (or at least I need to submit that with the form)? Berlin Brown
Wicket: On RadioChoice component, invoke form submit, what am I missing
There are some components in wicket that seem to be associated with a
form, but I can't get them to actually submit the form.
Or at least, I can't get them to submit the form, if I have a hierarchy
of FORM - PANEL - COMPONENT/RADIOCHOICE
For example, I can create a submitlink or button and those components
submit:
return new SubmitLink(id, form) {
@Override
public void onSubmit() {
this.setResponsePage(pageClass);
}
};
That works above.
I want to be able to perform a submit on a radio choice, on change. E.g.
new OnChangeHandler() {
@Override
public void onChange(final Object sel) {
// On submission, submit back to form
setResponsePage(Page.class);
}
// MY CONTAINER IS NOT A FORM BUT A CHILD OF A FORM (E.g. FORM - PANEL
- RADIOCHOICE
public RadioChoice addRadioGroup(final WebMarkupContainer container,
final Object modelObject,
final String groupName, final String propFieldName, final String []
optionsArr, final OnChangeHandler handler) {
final RadioChoice radioGroupYesNo = new RadioChoice(groupName, new
PropertyModel(modelObject, propFieldName), Arrays.asList(optionsArr)) {
@Override
public boolean wantOnSelectionChangedNotifications() {
return (handler != null); /* When the handler is not null, enable on
change */
}
@Override
public void onSelectionChanged(Object newSel) {
if (handler != null) {
handler.onChange(newSel);
} else {
super.onSelectionChanged(newSel);
}
}
};
container.add(radioGroupYesNo);
return radioGroupYesNo;
}
With the code shown above, the page refreshes, but I want to submit the
form and do a page refresh.
I don't see where I could associate the form with the RadioChoice?
Does RadioChoice need to imlement IFormSubmittingComponent?

How to access above hierarchy in the markup
Pseudo Code: CompoundPropertyModelString labelModel = new CompoundPropertyModelString(labelProps); panel.setDefaultModel(labelModel); /* Load labels at the PANEL level */ panel.add(new Label(label[1])); form = new Form(new CompoundPropertyModel(myObj)) /* Load data at the form level */ panel.add(form); form.add(myObj.fieldName); ...

With the current code, I can't access from the someLabelFromPanelLevel data or I will get a accessing outside of the hierarchy error message. I wish I could do the following (way to access higher up the hierarchy) Markup: panel.html: form wicket:id=theform div wicket:id=/PAGE:PANEL:someLabelFromPanelLevel / -- I want to access from the labelProps input wicket:id=someFieldFromMyObjFormLevel / -- I want to access from myObj /form - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
wantOnSelectionChangedNotifications and form components. and keeping state
I have an object in session and want to keep the state of those values
when I refresh a page or my form submits back to the page.
Do I have to add on every component? It seems that I do. Also, how do
I add want on selection change but NOT have it perform a form submit.
public boolean wantOnSelectionChangedNotifications() {
return true;
}
Issues with form submit, not retaining values from session without ajax
I have a page that has a html components like a select list and radio
buttons. And those components will invoke the onchange event to submit
the form or move to the next page.
It doesn't look like I am moving to the next page. My model values
dont' seem to be retained, at least they aren't retained in for the
radio buttons, text boxes.
For example, I was thinking like Struts or Spring, I would call
onchange on a radio button, the page would reload and all of my values
would be retained. The values are NOT retained.
Here are two radio buttons. I want to select one, do an onchange and
have retain the value of radiogroup2. That is not happening:
Also, I am losing the values of my textfields.
What would I need to to keep the values of the widgets regardless if I
submit the page or do an onchange.

wicket hell
There is a css hell, html hell, java web app hell. Is there a wicket hell or issues that are specific to wicket? Because I do believe web application development is wicket is pretty unique. I am still new to wicket but there are two gripes that get me every time. And maybe over time, I will get used to the problem. 1. Hierarchy issues - The hierarchy is very strict and not like the Java hierarchy. If you want to reference a component, it must be added properly in the markup and in the java code. This can be caught at compile time, but it is still takes time getting used to. 2. Unexpected behavior with the markup - Sometimes I expect a particular attribute or piece of code to get output but some tags I add in the markup get replaced by wicket. (E.g. I added class= to a div and the class attribute was removed) Note: I am not saying wicket is hell, or css or html is. But I was just pointing out that even wicket can have some quirks. Am I wrong here? Berlin Brown

General question - business logic with Wicket, where to put it?
What is the best practice for where to put business logic in Wicket. At first, I had put logic in the page constructor, but now I have learned a little bit about the Lifecycle of a page, the serialization of the page. So putting any kind of logic there didn't seem like a good idea. I placed logic in the action buttons onSubmit methods and form onSubmit methods. Placing any logic here in the onSubmits methods are OK, but sometimes it is difficult to find all the dependent objects. I gues I am used to a Struts MVC approach, where you have one Page action and then communicate with all of your dependent objects (say a form bean with all of the data); With Wicket, I see these issues: 1. When will the page constructor get invoked (should any kind of business logic be placed here?) 2. Where and when will the onSubmit/onUpdate action methods get invoked (should any business logic be placed here and are all the dependent objects available) Berlin Brown

check where Wicket serializes those files?

Understanding wicket lifecycle and model past to wicket components
I have two scenarios, a and b. In one case I use the loadable
detachable model and the other I don't. Is it possible when the wicket
component in scenario b is deserialized, is it possible that the object
won't be available?

final AppBean AppApplication = (AppBean)

return AppApplication;
}
};
});

QUESTION: in scenario (B), is it possible that the call to create the

Because the constructor was not called to render that page again.

RE: Understanding the model, initial/default value
And my pseudo code was wrong, I meant to add the model to a component.
final IModelBoolean modelForAgree = new
ModelBoolean(yes.equalsIgnoreCase(obj.getAgree(;
final AjaxCheckBox yesChoiceBox = new AjaxCheckBox( Agree, modelForAgree) {
}
form.add(yesChoiceBox)
I have another question, in the case of the checkbox, it expects a model with a
boolean value.
I would need to add a property field that holds a boolean? Is this correct.
Let's say the property has a string?

You're not binding your model to the agree property, really. So, if the
value changes, it won't update your model. If you want to bind it, use a
PropertyModel.

Initialization/Business Logic code before page loads
I might have asked a similar question in a previous post but I wanted to
clarify a bit.
Where is the best place to put code to initialize the model before a
page renders. I know of five options, but where do you normally put
this type of initialization.
Before a page renders, I want to set the data in my bean/model with
certain attributes that may only be specific to that page.
I think there are five options.
1. Add initialization logic in the constructor. This may work, but I
don't know if the constructor is called for every page call (E.g. when
the page is deserialized)
2. Add init logic in onBeforeRender. This works and it called for every
request? But is it the best place?
3. Add init logic in a load or getmodel method in
LoadableDetachableModel class?
4. Add init in previous page on onSubmit method or onEvent. (onSubmit()
{ initBeanInSession(); setResponsePage(); }
5. Pass a model to a panel or page constructor (using pageparameters?)
Are any of these best practices or preferred over the other.
(a) Page Constructor code with Loadable detachable model:
MyPage.java:
...
final FormMyBean form = new FormMyBean(FORM, new
CompoundPropertyModelMyBean(new LoadableDetachableModelMyBean() {
private static final long serialVersionUID = 1L;
@Override
protected MyBean load() {
final MyBean app = (MyBean) Session.get().getApp();
?
?
initialize here???
?
return app;
}
};
});
???
onBeforeRender() {
?? Add initiailize here
final MyBean app = (MyBean) Session.get().getApp();
app.setData(doSomeBusinessLogicHere)
}
or initModel?

For objects out of session, work with directly or use loadable detachable model
For objects that I get from session, I was trying to avoid accessing
them in the constructor but I wanted to setup my default model so that
they are pulled on the load method from a loadabledetachable model.
Which approach do you use? Here are the three approaches,
(The code below is pseudo code, I am typing it out from memory).
** Scenario 1. Add a call to the constructor.
public class SomePage extends Page {
public SomePage() {
...
...
final bigSessObjBean = WicketSession.get().getSomeObjBean(); ---
Access object from session in local constructor method scope.
final Form x = new Form(form, new
ModelObjBean(bigSessObjBean)) { --- Obj bean as default model
...
}
or even...
final Form x = new Form(form) {
...
onSubmit() {
bigSessObjBean.getData(); Here, accessing bigSess
Obj Bean
}
}
}
}
** Scenario 2. Use loadable detachable Model
public class SomePage extends Page {
public SomePage() {
...
...
l = new LoadableDetachableModel() {
public Bean load() {
return WicketSession.get().getSessBeanObj();
}
};
final Form x = new Form(form, l) {
...
onSubmit() {
getDefaultModel().getData(); Here, accessing bigSess
Obj Bean
}
}
}
}
** Scenario 3: Call the session get when you need it.
final Form x = new Form(form, l) {
...
onSubmit() {
WicketSession.get().getSessBeanObj();.getData(); Here,
accessing bigSess Obj Bean
}
}

Another similar question based on your question.

E.g. as opposed to document.forms[xxx].submit(). Is there some generic
ajax submit I could use.

this.add(new AjaxLinkObject(nextLink) {
@Override
public void onClick(final AjaxRequestTarget target)
{
// Find the dynamic form on the page.
final Object objAtStopTraversal =
HomePage.this.visitChildren(new FindFormVisitor());
if (objAtStopTraversal instanceof Form?) {
// Form found, invoke javascript submit
final Form? form = (Form?)
objAtStopTraversal;
target.appendJavascript(String.format(try {
document.forms['%s'].submit(); } catch(err) { if (window.console !=

you can submit any form with pure javascript:

this will call the respective myForm.onSubmit() method at the server

at server side you may call directly your methods e.g.
new Form() {onSubmit() { myService.do(); }} new AjaxLink() {onClick() {

Because in my traffic light scenario, I want to return to the original

Compound Property Model, sharing for children
How does the compound property model work in these instances:
If I do (pseudo code):
Form form = new Form ( new CompoundPropertyModel(someObject))
form.add (new MyTextField(someFieldFromObject);
...
public class MyTextField {
public MyTextField() {
super(id);
getModel() - will this return an object?
getModelObject() -- will this return an object?
}
}
Basically, when is the model object and model bound to a component that
uses the compound property model.

RE: Compound Property Model, sharing for children
Also, I am assuming a call to compoundPropertyModel.bind(expression) is
called, does this return a property model? Or is more involved?
New
TextField().setDefaultModel(compoundPropertyModel.bind(obj.fieldName))
; -- return a propertymodel.
If I change the instance of modelobject obj in the case above, how
does the compound property model use the new instance. E.g:
public class SomeObject {
public class Inner {
fieldName
}
private SomeObject.Inner obj;
getObj() { }
setObj() { }
}
SomeObject someObjectMain = new SomeObject()
Form form = new Form ( new CompoundPropertyModel(new SomeObject()));
form.add (new MyTextField(obj.fieldName);
someObjectMain.setObj(new SomeObject.Inner()); --- In this case, will
the model object for the text field be updated and how??

Subject: Re: Compound Property Model, sharing for children
No because the MyTextField will not be able to init its model based on
the parent CompoundPropertyModel since it don't know him yet. Only after
exit the form.add call MyTextField.getModel will work as expected.
If MyTextField invokes getModel inside the onInitialize it will work
fine, since at this point since an path exists from this component to
the page.

getModel() - will this return an object?

Basically, when is the model object and model bound to a component
that uses the compound property model.

RE: Submit form from ajaxlink not a part of the form
I added a kind of dummy ajax submit link on that form and then try to invoke
that link... When I get a reference to the callback URL. Here is the error.
Is there a way to debug that object error? I could try changing:
1. ignore if not active to false?
2. changing some of the parameters to the submit call?
3. hiddenSubmitLink ...maybe that is not the correct path to that link... Maybe
I need to try
panel:form:hiddenSubmitLink...etc?

Cheap chaining of compound property model to propertymodel
In this code, do you think I am using the method
CompoundPropertyModel.bind properly? See my example in Code2, below.
In my snippet Code1, the values for the propertymodel were lost when I
did an ajax onClick.
But in Code2, the values are retained...
Code1:
Panel {
Panel() {
CompoundPropertyModel compoundPropertyModel = new
CompoundPropertyModel(someObject);
Form f = new Form(compoundPropertyModel);
f.add(new TextField(name)); This works fine, data able to
setObject and getObject on ajax and other cases
f.add(new TextField(name, new PropertyModel(someObject); --- ON
AJAX, VALUES LOST
f.add(new AjaxLink() {
onClick() {
target.add(form);
}
}
}
}
...
...
Code2:
As a fix, I did the following:
final PropertyModel pm = new
PropertyModel(compoundPropertyModel, number) {
@Override
public Object getObject() {
return ((CompoundPropertyModel)
form.getDefaultModel()).bind(number).getObject();
}
public void setObject(final Object obj) {
((CompoundPropertyModel)
billingForm.getDefaultModel()).bind(number).setObject(obj);
}
};
f.add(new TextField(name)); This works fine, data able to
setObject and getObject on ajax and other cases
f.add(new TextField(name, pm)--- ON AJAX, NOW VALUES ARE
AVAILABLE, FIXED!

Static member wicket version... post 1.4.13

Issue with error validation and onChange event of a dropdown
In the example below.
StepOne: user enters INVALID DATA
StepTwo: user hits the SAVE LINK (see below)
StepThree: error is displayed in feedback panel
StepFour: user enters to select drop down, onchange
StepFiveERROR :: the code below should update the model, see Line12
But when the panel is displayed the textboxes don't have the value
Hello
When I do onchange from the dropdown, the value is set to empty. If
there is NO ERROR from the validation then everything is fine.
Possible issue? I tried to clear the error messages onUpdate but that
didn't help.I also added onError event and the error was only hit
during validation.
It is strange because onUpdate is called and it looks like the value is
getting set in the model (Line12) but that value is not displayed in the
textfield.
Only Other Solution? Maybe I need to do a force submit in the
onChange/onUpdate method?
Pseudo Code:
Panel {
Form form = new Form(new CompoundPropertyModel());
add(form);
form.add(new TextField(val);
form.add(childList = new DropDownChoice());
childList.add( new AjaxFormComponentUpdatingBehavior(onchange) {
protected void onUpdate( final AjaxRequestTarget target ) {
/// Tried clearing the messages here, does not work.
Line12: form.getObjectModel().setVal(Hello);
- VALUE NOT BEING REFRESHED ON ERROR when I
redisplay the panel.
target.addComponent(panel);
target.addComponent(form);
}
});
form.add(new MyValidator()); -- VALIDATE, HAS ERROR!!!S
form.add(new AjaxSubmitLink(form)) {
onSubmit() {
save();
moveToNextScreen();
}
}
}
Wicket Philosophy/Best Practice
I tell people that I think you should let your Model and Model backing
object control the look and feel/display/content of your components.
Even visibility should be delegated to the model or model object and not
set by the component. Am I wrong here?
I use this approach (only work with the Model/ModelObject) as opposed to
monkeying with the wicket internal(seemingly) methods like
onComponentTag or adding javascript to control the look feel or tags?
E.g.
MyComponent {
isVisible() {
getModelObject().isVisible();
}
isEnabled() {
getModelObject().isEnabled();
}
}
Berlin Brown
Ajax onChange but also submit all data on a form
Can you submit all of the data on a form based on an onchange event?
Is adding javascript the only way to submit the data?
Pseudo Code:
Panel {
Form form = new Form(new CompoundPropertyModel());
add(form);
form.add(new TextField(val);
form.add(childList = new DropDownChoice());
childList.add( new AjaxFormComponentUpdatingBehavior(onchange) {
protected void onUpdate( final AjaxRequestTarget target ) {
/// Tried clearing the messages here, does not work.
Line12: form.getObjectModel().setVal(Hello);
target.addComponent(panel);
target.addComponent(form);
}
});
form.add(new MyValidator());
form.add(new AjaxSubmitLink(form)) {
onSubmit() {
save();
moveToNextScreen();
}
}

Strange behavior with onUpdate after errors
Debugging Problem. I am trying to debug an issue where I set
modelobject values for a form but the values do not appear in the text
fields onUpdate (AFTER ERROR) encountered.
Environment:
A. Wicket 1.4.13
B. Ajax Tabbed Panel
C. Modal Window
D. Child Modal Window has a form (compound property model)
E. Form has text components
F. Form has a drop down box, on change the behavior set model values.
F. Form has a abstract validator
Recreating the issue:
1. Click on link to bring up modal window
2. Click on drop down box, ajax form behavior on change, sets values in
text fields.
3. Click on drop down box, ajax form behavior on change, sets values in
text fields (this part works FINE!!)
4. Click the null value/default selection on drop drown box
5. Click ajax save link
6. ERROR generated
7, go back to step 3 and click on the drop down box, now the values do
NOT UPDATE IN THE TEXT FIELDS (but they worked in step 3).
Basically, my ajax drop down worked fine WITHOUT THE error, but after a
validation error, the text field values do not appear in the form.
...
Debugging the issue.
It is strange that the model seems to have the value I want but in the
raw input does not.
Here is me overriding behavior in the textfield:
MyTextField {
...
@Override
protected void onComponentTag(final ComponentTag tag)
{
System.out.println(-:textComponent:modelValue: +
getModelValue());
System.out.println(-:textComponent:rawInput: +
getRawInput());
System.out.println(-:textComponent:getValue: +
getValue());
// Default handling for component tag
super.onComponentTag(tag);
}
}
...Output:
SystemOut O :==222y:George
SystemOut O -:textComponent:modelValue:George
SystemOut O -:textComponent:rawInput:
SystemOut O -:textComponent:getValue:
Why is the model value NOT null but the raw input is?
...
Some more code:
...
final FormmyBean form = new FormmyBean(calloutForm,
compoundPropertyModelForForm);
...
final MyDropDownChoice childList = new MyDropDownChoice(childList,
dropDownModelChild, renderer);
childListContainer.add(childList);
childList.add( new AjaxFormComponentUpdatingBehavior(onchange) {
@Override
protected void onUpdate( final AjaxRequestTarget target ) {
BaseWicketSession.get().getFeedbackMessages().clear();
BaseWicketSession.get().cleanupFeedbackMessages();
SelectionOptionBean myChildSelected =
(SelectionOptionBean)getFormComponent().getDefaultModelObject();
final myBean myBeanLoc = form.getModelObject();
THIS CODE BELOW THE VALUES ARE SET !!!
myBean selectedChild = getChildDataFromData();
myBeanLoc.setFirstName(selectedChild.getFirstName());
myBeanLoc.setLastName(selectedChild.getLastName());
myBeanLoc.setMiddleName(selectedChild.getMiddleName());
target.addComponent(ccc);
System.out.println(:==221x: + myBeanLoc);
System.out.println(:==222y: + myBeanLoc.getFirstName() +
- + myBeanLoc.getLastName());
System.out.println(!!);
}
} );
...
final AjaxSubmitLink saveLink = new AjaxSubmitLink(saveLink, form) {
@Override
public void onSubmit(final AjaxRequestTarget target, final
Form? form) {
modalWindow.onSave(target, null);
target.addComponent(form);
}
};
...
WITH THE ERROR, the HTML renders WITHOUT THE values. But when I print
the model object values, it looks like they are there.
OUTPUT FROM THE HTML:
input type=text size=28 maxlength=20 class=field value=
name=lastName/
RE: Strange behavior with onUpdate after errors
OK, After doing some research, I call modelChanging and modelChanged();
@Override
protected void onUpdate( final AjaxRequestTarget target ) {
CALL form.modelChanging();
SelectionOptionBean myChildSelected =
(SelectionOptionBean)getFormComponent().getDefaultModelObject();
final myBean myBeanLoc = form.getModelObject();
THIS CODE BELOW THE VALUES ARE SET !!!
myBean selectedChild = getChildDataFromData();
myBeanLoc.setFirstName(selectedChild.getFirstName());
myBeanLoc.setLastName(selectedChild.getLastName());
myBeanLoc.setMiddleName(selectedChild.getMiddleName());
CALL form.modelChanged();
target.addComponent(ccc);}

Ajax like event for onLoad
I am using the Ajax Tabbed Panel class and I could possibly hijack the
onUpdate/onClick routines to suit my needs.
But I was curious, is there an event/behavior that I can call when a

Something along the lines of:
SomeAjaxPanel {
onBeforeRender() {
this.add(AjaxBehavior(onload') {
onEvent(target) {
}
}

Wicket log4j configuration, log wicket errors to file
I think I was able to log wicket log4j messages (pre wicket verson 1.4.10) by specificying a log4j appender for the wicket package. E.g. org.apache.wicket.* But, I wonder with the recent version of wicket, do I have to use org.slf4j.impl ... Basically, is there anything special to redirect wicket logging messages through log4j? [2/18/11 15:45:24:747 EST] 0024 RequestCycle E org.slf4j.impl.JCLLoggerAdapter error org.apache.wicket.WicketRuntimeException: Internal error parsing wicket:interface = SDFSD org.apache.wicket.protocol.http.request.InvalidUrlException: org.apache.wicket.WicketRuntimeException: Internal error parsing wicket:interface = SDFSD at org.apache.wicket.protocol.http.request.WebRequestCodingStrategy.decode( WebRequestCodingStrategy.java:235) at org.apache.wicket.Request.getRequestParameters(Request.java:183) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1310) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1436)
Typically when is the constructor of a component of a panel, page, etc called?
I was trying to get a feel for the wicket lifecycle, I can where
onBeforeRender, onAfterRender are called during the component rendering
lifecycle. But, I still don't see when the constructor (object
instantiation) of a component. If I debug and/or trace the constructor
calls, it looks like the component is instantiated every time is
rendered?
With ajax components, when is the constructor of a component called? In
my case below, when is the MyPanel constructor called. Only once? when
the object is added to the ajax tabbed panel. Or when the content is
rerendered?
AjaxTabbedPanel ajaxTabbedPanel
...
public class MyPanel extends Panel {
public MyPanel() {
... add components.
}
}
new Page();
ajaxTabbedPanel.addTheMyPanelToAjaxPanel(new MyPanel));
thePage.add(ajaxTabbedPanel)
...
onClickOfTab {
target.addComponent(myPanel)
}
Wicket philosophy, modelObject isVisible, isEnabled, CSS
Most of the backing modelObject and models are normally associated with
the data that is to be displayed or edited. Isn't the CSS and
visibility one aspect that is part of the display?
What are your thoughts on controlling the visibility, enabled state and
CSS through the model objects as opposed at the component? Where do you
draw the line between how the component should work and how the data
should manipulate the component?
public class DataWithCSS {
public String getValue() {
return value;
}
public String getCSS() {
return css
}
}
For example, let's say you have a text box that has two backing objects:
Label label = new LabelDataWithCSS(new DataWithCSS(Hello World,
style-red)) {
onComponentTag() {
tag.put(class, this.getCSS())
}
}
...
I know we can add functionality that will pull the data value and CSS or
visbility or other attributes from the model and model objects, I was
just curious if the wicket developers intended for some aspects to be
more controlled at the component level.
Good way to remove validation globally from a page or panel
If I am using AbstractFormValidator and in some places, I am using setRequired, default validation on components. What is the best way to remove the validation temporarily Let's say I am in a view only mode and fields are disabled, I want to remove validation. And then later on, may add back that validation. I guess I Could remove and add onBeforeRender or initialize or configure and then add the validators back. I was trying to avoid doin that. I would have to remove validation on all the components on those particular pages. Also, I was thinking of just exiting early in the validation methods? Also, let's say I have some fields that are disabled and some that aren't. I am using abstractformvalidator and throwing an error if those fields are empty. They are empty but disabled. Is there a way to treat disabled fields differently in validation modes..
RE: Good way to remove validation globally from a page or panel
I should have clarified.
Yea, if you have input fields with a dozen or so fields and you have 50%
disabled. But you are using the AbstractFormValidator validate() {
get(field1).getInput; get(field2).getInput ... And doing validation
checks, I guess this isn't a good approach.
I have to keep the fields disabled and can't use true/read only spans.
I could visit each field and check if the component is enabled or not,
but I was trying to see if there is a one liner, easy solution that I
could remove validation in a disabled state...if I use the validation
approach I mention above.

When you are in View mode then either your components are not form
components (e.g. input is replaced with label/span/...) or as you
said they are disabled. Form submit will not send name/value pair for
disabled form elements.
I think the first approach is better regarding user experience.
See visural's view or edit components for example.

Deserialize/cache components in Ajax rendering and other scenarios
It looks like caching and the deserializing of pages only happens when the user revisits a page or goes back to a page? Is there any serialization/deserialization that is done to panels if they are just rerendered through ajax? If your whole site is ajax based (where most of the content is not rendered through pages but panels), I guess we don't get the benefits of the wicket caching? Also, does anyone have more information when the wicket page caching kicks in? I only see it deserialize a page when you visit the javascript back button.
Ajax modal window does not allow submit form under open browsers
When I use the ajax modal window and under Firefox/Chrome/Safari, the

To submit a form inside a modal window you must enclose it by a form in
the main panel and use an AJAX submit component. Please open a ticket +
quickstart if the issue remains.

RE: Apache Wicket Cookbook Published!
Congrats. I trust Igor -Original Message- From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] Sent: Friday, March 25, 2011 1:44 PM To: users@wicket.apache.org; d...@wicket.apache.org; annou...@wicket.apache.org Subject: Apache Wicket Cookbook Published! For the past nine months I have been quietly working on a book about Wicket. Unlike other books on the market this one does not attempt to teach you Wicket from the ground up. Instead, it is for developers who already know the basics and want to learn how to implement some of the more advanced use cases. Essentially, it contains recipes that show the reader how to implement solutions to some of, what I think are, the most commonly asked questions and stumbling blocks. This morning I was informed that the book has been published! You can read more about it and pick up a copy on PACKT's Site[1]. I hope you enjoy it, more details below... [1] https://www.packtpub.com/apache-wicket-cookbook/book ## Description ## Apache Wicket is one of the most famous Java web application frameworks. Wicket simplifies web development and makes it fun. Are you bored of going through countless pages of theory to find out how to get your web development done? With this book in hand, you don't need to go through hundreds of pages to figure out how you will actually build a web application. You will get practical solutions to your common everyday development tasks to pace up your development activities. Apache Wicket Cookbook provides you with information that gets your problems solved quickly without beating around the bush. This book is perfect for you if you are ready to take the next step from tutorials and step into the practical world. It will take you beyond the basics of using Apache Wicket and show you how to leverage Wicket's advanced features to create simpler and more maintainable solutions to what at first may seem complex problems. You will learn how to integrate with client-side technologies such as JavaScript libraries or Flash components, which will help you to build your application faster. You will discover how to use Wicket paradigms to factor out commonly used code into custom Components, which will reduce the maintenance cost of your application, and how to leverage the existing Wicket Components to make your own code simpler. A straightforward Cookbook with highly focused practical recipes to make your web application development easier with the Wicket web framework ## What you will learn from this book ## * Leverage Wicket to implement a wide variety of both simple and advanced use cases in a narrative that gets straight to the point * Make forms work in the crazy world of the Web by learning the ways of Wicket's form processing * Simplify localizing your Wicket applications * Take the boring out of your forms by discovering how to improve the user experience while simplifying your code at the same time * Leverage the built-in Table component to make displaying tabular data a snap * Think Wicket's Borders are not very useful? Learn to use them in unexpected places to simplify things * See how to integrate with Flash components and create interactive charts at the same time * Web 1.0 too boring? Learn how to tame Wicket's AJAX support and bring your application into Web 2.0 * Simplify your security code by learning various security techniques * An application cannot be built with Wicket alone; see how to make it play nice with other frameworks ## Approach ## This is a hands-on practical guide to a large variety of topics and use cases. This book tries to use real-world examples when possible, but is not afraid to come up with a contrived pretext if it makes explaining the problem simpler. Unlike a lot of other books, this one does not try to maintain a continuous theme from chapter to chapter, such as demonstrating solutions on the same fictional application; doing so would be almost impossible given the wide variety of recipes presented here. Instead, this book concentrates on focused problems users are likely to encounter and shows clear solutions in a step-by-step manner. This book tries to teach by example and is not afraid to show a lot of code because, after all, it is for coders. ## Who this book is written for ## This book is for current users of the Apache Wicket framework; it is not an introduction to Wicket that will bore you with tons of theory. You are expected to have built or maintained a simple Wicket application in the past and to be looking to learn new and better ways of using Wicket. If you are ready to take your Wicket skills to the next level this book is for you. Cheers, and I hope you enjoy the book! -Igor - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail:
Ajax Submit Link and detect if that button clicked
I was having trouble detecting if a particular ajax submit link was the last behavior associated with a form submission. I tried to use the findSubmittingButton (or whatever the name is) and that was always returning null. I used this approach and it works, but doesn't seem intuitintive and I wonder if there is a better way. final String lastURL = form.getWebRequest().getURL(); return (lastURL.indexOf(nextLink) != -1); or whatever the link is in the URL.

Deserialization of pages with Wicket, back button
When does wicket use the deserialization of pages from the filesystem
disk store/cache?
With the default, out of the box Wicket code, when does Wicket
deserialize a page?
Pseudo-code:
getHomePage() {
return Page.class
}
...
Let's say I am using ajax or ajax tabbed panels and I am not really
instantiate new pages to re-render screens (E.g. with AjaxTabPanel, only
that panel gets rerendered), do panels get deserialized outside page
deserialization? Or is it only a full page?
As far as I can tell, it looks like it only happens when you use the web
browser 'back' button? But shouldn't it happen when I refresh a page?
RE: Deserialization of pages with Wicket, back button
Clicking back button will lead you to the previous page, not to the
previous state of the page.
Refreshing the page reloads the current version of the page which is in
the http session and thus doesn't hit the file system.
I think you answered the question, just wanted to confirm.
When does the deserialization from the filesystem happen?

Strange error, cannot modify hierarchy
I am shooting in the dark but I thought I would post the error I am
getting.
I get this error. Cannot modify component hierarchy after render phase
has started. The full stack trace is at the bottom of this post.
During the form submission process (user clicks on link) then I get the
error above but ONLY when I have a dynamic component with
isTransparentResolver = true.
If I restructure my hierarchy such that transparentResolver is false
then I don't get the same error. Why do you think I get the error?
...
final WebMarkupContainer container = new WebMarkupContainer(
container ) {
public boolean isTransparentResolver() {
return false; // true causes error
}
@Override
public boolean isVisible() {
return logic();
}
};

Google Chrome and Apache Wicket, an awesome combination
FYI... I usually ask questions but I thought I post a comment about google chrome. The chrome browser has default web debugging that is similar to firebug. With Firebug, it is more difficult to detect the wicket ajax rendered content but comes up automatically in chrome. Also speed wise, chrome renders much faster than IE or Firefox. I tested Ajax oriented complex content and chrome just works quickly.
Differences development vs deployment mode, hierarchy errors
I noticed with the web.xml configuration, development mode that I see more hierarchy exceptions thrown by wicket. Basically, it seems that wicket ignores some hierarchy or markup issues in development mode and not in deployment mode. What are the main differences between those modes and how do I know what exceptions will be thrown?
Slow ajax request and possible timeout variable?
Sometimes on slower connections I see issues with the application with ajax requests. If the request takes longer than 20 or 30 seconds my page/panels become unresponsive? Example pseudo code might include; new TextField(text).add(new AjaxBehavior(onchange)); With this request, the ajax request never returns ... say after 30 seconds. And the bevhaior is diferent for different browsers. IE8 may have an issue but Chrome does not. Is there something I could debug to see if this is the case? Is there some sort of issue or timeout with ajax requests.
RE: Slow ajax request and possible timeout variable?
This bug seems to be related to the issue I am experiencing. https://issues.apache.org/jira/browse/WICKET-2246 From: Brown, Berlin [GCG-PFS] Sent: Wednesday, May 25, 2011 11:57 PM To: 'users@wicket.apache.org' Subject: Slow ajax request and possible timeout variable? Sometimes on slower connections I see issues with the application with ajax requests. If the request takes longer than 20 or 30 seconds my page/panels become unresponsive? Example pseudo code might include; new TextField(text).add(new AjaxBehavior(onchange)); With this request, the ajax request never returns ... say after 30 seconds. And the bevhaior is diferent for different browsers. IE8 may have an issue but Chrome does not. Is there something I could debug to see if this is the case? Is there some sort of issue or timeout with ajax requests.

Request logger invasive
Is the request logger invasive? Is it something that can be used in a production environment? http://www.volkomenjuist.nl/blog/2009/04/08/wicket-requestlogger/
Wicket, invalidurlexception with ajax panel, possibly ajax calls
I am getting this error intermittently with a web application that uses
ajax calls. My theory is that on slower Internet connections, parts of
a page aren't returned at the correct time. With the ajax call, maybe a
user clicks on a link but the link hasn't been entirely processed by the
server back end.
Error:
org.apache.wicket.protocol.http.request.InvalidUrlException:

Version: Wicket1.4.13
Pseudo Code:
I am using the wicket ajax tabbed panel. On the panel, there is a link
added to the tabbed panel. And the tabs are added to the page. We
normally don't refresh the entire page. Content is controlled by the
ajax tabbed panel system.
It looks like I am getting the invalid URL exception on the link. I
haven't been able to recreate the error. It is something that the end
user tends to see.

Fun story follows... We just solved a strange bug in our own application where users were logged out after a certain, but random amount of time, and where other users reported being thrown out every 5 minutes. We couldn't discover what happened, and after logging everything sessionid related, we noticed two cookies being sent (that we added ourselves in the application). Looking at the client side of things, we finally saw that we were generating those 2 cookies for each path in the application-which was really increased since we introduced bookmarkable URLs... It appears that browsers have a limit for the amount of cookies per domain, and that each browser behaves differently when the limit is reached: - safari/chrome: no limit what soever - IE: 50 cookies, FIFO - FF: 50 cookies, random eviction Since we convinced many of our users to switch to firefox, they got thrown out at random times... Only the die hards with 'conservative' sys admins that are using IE were thrown out consistently. So long story short: check your cookies.

Override modal.js functionality because of issue with form inside form
I am using a dated version of wicket. I don't know if this is fixed but I wanted to override the functionality in the modal.js from wicket-extensions.

Some of the browsers we are using, the user cannot submit the form from a modal window (maybe our page layout is at fault). What is a non-invasive way of doing this (least amount of code changes)? It looks like a lot of the methods in the ModalWindow class are private or static, I was thinking of just overriding that class or reimplementing that class and passing my own javascript with modified functionality. Here is the javascript I needed to change: ... res/modal.js div class=\wicket-modal\ id=\+idWindow+\ style=\top: 10px; left: 10px; width: 100px;\form style='background-color:transparent;padding:0px;margin:0px;border-width: 0px;position:static'+

Nested forms inside a modal window works nice even in old versions. It is important because it prevents invalid markup like form tag inside form tag. About improvements in modal window, it is already planned to Wicket 1.6.

I don't know if this is fixed but I wanted to override the functionality in the modal.js from wicket-extensions. Basically, I need to remove the inner form that is created by the javascript. Some of the browsers we are using, the user cannot submit the form from a modal window (maybe our page layout is at fault). What is a non-invasive way of doing this (least amount of code changes)? It looks like a lot of the methods in the ModalWindow class are private or static, I was thinking of just overriding that class or reimplementing that class and passing my own javascript with modified functionality. Here is the javascript I needed to change: ... res/modal.js div class=\wicket-modal\ id=\+idWindow+\ style=\top: 10px; left: 10px; width: 100px;\form style='background-color:transparent;padding:0px;margin:0px;border-width: 0px;position:static'+ -- Pedro Henrique Oliveira dos Santos - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
PageExpiredException with multiple browser windows, ajaxformupdating behavior
I am getting a PageExpiredException. I believe it is related to a user
opening multiple browser windows. They are using the same session and
accessing the same page at the same time. I was thinking that the page
will expire in one window but not the other for some reason.
User actions;
1. Open a window (with that Page)
2. Open another (with that Page)
3. Click around in one window for a couple of minutes
4. Maybe the user will go BACK to the first window and click
5. Receive PageExpiredException when they click on an ajax component.
I can concede that maybe having having multiple windows and accessing
the same session is not a good idea. I can restrict the user such that
they only open one window.
But, I just wanted to know if anyone had this issue and why.
Here is the strange part, if the user clicks fast enough in both
windows, window-a and window-b then they DON'T get the
PageExpiredException. But if the user waits a minute or maybe around 30
seconds on one page, they get the PageExpiredException.
Maybe the page is written to disk after 30 seconds or so?
Here is essentially the page structure:

target.addComponent and impact
If you have an ajax event and then you call target.addComponent on another component or collection of other components. Are there issues with calling target.addComponent on components that aren't visible or maybe detached from the page? Or calling target.addComponent more than once on a particular component?
RE: target.addComponent and impact
Let's say that I have a component in the hashmap that needs to get updated and let's that I call target.addComponent on some parent component, in that case will the child get updated twice. E.g. Target.addComponent(someChildComponent); Target.addComponent(someParentOfTheChild); In this case, will child get updated twice or still just once ... Because the parent will take care of having the child updated? -Original Message- From: Andrea Del Bene [mailto:adelb...@ciseonweb.it] Sent: Thursday, July 14, 2011 11:55 AM To: users@wicket.apache.org Subject: Re: target.addComponent and impact Right, I've looked at code and it uses an hashmap in last case i think rendering will be once because the components are kept in map with markupid of component as key in ajaxrequesttarget.

One more question. Is it is a hint to update this particular component?

getInput and getDefaultModelObject and validation
If I am using some form validator, I notice that getDefaultModelObject
does not have the value from the getInput. I am assume this
intentional. Is there a way to force wicket to update the modelObject?
How and when does the modelobject get updated.
myForm.add(new AbstractFormValidator() {
public void validate() {
String val = component.getInput(); --- has the correct value
from the request
String val2 = component.getModelObject(); does not have
value.
}
});
...
In the case above, I could use the proper ajaxbehavior (like onBlur on a
textfield) and the modelObject gets updated.
But if I weren't using ajax, is there a way to force wicket to update
the modelObject.
RE: getInput and getDefaultModelObject and validation
I guess there are cases where you want to use an AbstractFormValidator
and run validation on a form before it is submitted and want to address
those fields before they are submitted. It would be nice if the
modelobject were updated.
Let's say you have 100 textfields attached to a form, you want to
validate some of the fields, all at once (say using FormValidator
attached to the form),
Is there a way to force a modelobject update on each individual field
and then do my form validation. (I guess the only way is through ajax
events on each field).
E.g.
Form.add(new TextField);
Form.add(new TextField);
Form.add(new TextField);
Form.add(new TextField);
Form.add(new TextField);
Form.add(new AbstractFormValidator() {
onValidate() {
if (textField1.getInput() == creditCard) {
}
}
});
...
With the code above, I have to do all of my form validation without my
desired type.

Yes, form component models are not updated until they pass validation,
that is very intentional. :)
(E.g. if you have a Date text field and someone types beer, what would
you expect to be written to the model?)

When all validation succeeds and it progresses into a submit.
But if I weren't using ajax, is there a way to force wicket to update
the modelObject.
That will happen automatically after validation passes. Validation
should ideally only check inputs and give any errors.

RE: getInput and getDefaultModelObject and validation
then your model will have invalid data, and if that is acceptable,
what role does the validator fill then? You might as well do your checks
in onSubmit() at that point...
I guess it depends, I normally haven't had a need to validate every
individual component. But I like having all of my model objects with
their values and then doing validation of those values/types before the
form is submitted.
getConvertedInput would work
what role does the backing object fill if you can't using them during
your validation.
I guess in some cases you want an override switch to allow the model
object to get updated with the input pre-validation.
...
As a hack, we normally just add ajaxbehaviors on the components and
their values get updated, then I can do form validation with all the
updated models.

It seems you want to use getConvertedInput(). Going via the model to get
the converted value is just a detour when you are in a validator. If you
push data to the model and then decide it is invalid, then your model
will have invalid data, and if that is acceptable, what role does the
validator fill then? You might as well do your checks in onSubmit() at
that point...
if (textField1.getInput() == creditCard) {
You should be aware that this code will most likely fail. Look into
equals().

RE: Cheap, ajax event on page load
Well, I guess I figured out how you can easily get a page expired
exception or invalidurlexception. If you hide the component where the
timer behavior was created from before the timer behavior comes back,
then you get an error.

Subject: Cheap, ajax event on page load
Using timerbehavior for an ajax onload. I have been wanting an on page
load ajax request. There isn't one builtin but I have used this
recently. Using ajax timer behavior, use the onTimer event.
It works, except you have to wait for the timed interval to get invoked.
At a minimum, I use a second and not for critical operations. My only
concern with using this approach (besides the fact I using the class
outside of the normal use-case) is ensuring that the timer behavior is
removed properly.
Any see in issue with doing this? Browser compability issues with timer
behavior?
Class extends AbstractAjaxTimerBehavior
@Override
protected void onTimer(final AjaxRequestTarget target) {
if (counter = this.getMaxNumberIntervals()) {
try {
this.stop();
if (this.getComponent() != null) {
this.getComponent().remove(this);
}
} catch(Exception e) {
}
counter = 0;
} // End of if, check for removal
counter++;
}
