Re: Adding css resource available to all component in the application using wicket 9.x

[Francois Meillet]

Hi Arunachalam,

Migration From Wicket 7 to 8
setHeaderResponseDecorator(new 
JavaScriptToBodyCustomResponseDecorator("footer"));

Wicket 8
setHeaderResponseDecorator(response -> {
return new ResourceAggregator(new 
JavaScriptFilteredIntoFooterHeaderResponse(response, "footer"));
});

Wicket 9
getHeaderResponseDecorators().add(response -> new CustomResponse(response));

Re: RestartResponseException ajaxbutton

[Francois Meillet]

yes page id = null

Thanks Sven,

François



> Le 21 juil. 2021 à 16:32, Sven Meier  a écrit :

RestartResponseException ajaxbutton

[Francois Meillet]

I have two pages (identical) called PageOne and PageTwo, each with a form, 
mounted with an UnVersionedUrlMapper.

When I do a RestartResponseException in the submit (via an AjaxButton) to the 
same page (from pageOne to pageOne),
the PageOne's constructor is called twice. (onInitialize is called once)

But If I throw RestartResponseException (via an AjaxButton) from pageOne to 
pageTwo the PageTwo's constructor is called once or if I throw 
RestartResponseException (via a standard Button) from pageOne to pageOne the 
pageOne's constructor is called once.


Tested with all the 9.x


Here is the test the UnVersionedUrlMapper # mapHandler
if (requestHandler instanceof ListenerRequestHandler || requestHandler 
instanceof BookmarkableListenerRequestHandler) {
return null;
}
else {
return super.mapHandler(requestHandler);
}


Did I miss something or am I misusing RestartResponseException ?
Are the tests in the UnVersionedUrlMapper wrong ?

Thanks for your help.

Could you disable JavaScript in your browser and test your page ?
Or in your MetronicAssets, comment all JavaScriptReferenceHeaderItems.

Re: Locatable UnsupportedOperationException

[Francois Meillet]

Hope that help

During the process of throwing an exception, the Java Virtual Machine abruptly 
completes, one by one, any expressions, statements, method and constructor 
invocations, initializers, and field initialization expressions that have begun 
but not completed execution in the current thread. This process continues until 
a handler is found that indicates that it handles that particular exception by 
naming the class of the exception or a superclass of the class of the exception 
(§11.2 
<https://docs.oracle.com/javase/specs/jls/se11/html/jls-11.html#jls-11.2>). If 
no such handler is found, then the exception may be handled by one of a 
hierarchy of uncaught exception handlers (§11.3 
<https://docs.oracle.com/javase/specs/jls/se11/html/jls-11.html#jls-11.3>) - 
thus every effort is made to avoid letting an exception go unhandled.

Re: Locatable UnsupportedOperationException

[Francois Meillet]

Hi,

Depending on the model you use, you may need to ovveride the setObject() method.

from the API docs

default void setObject​(T object)

Throws:
UnsupportedOperationException - unless overridden


https://ci.apache.org/projects/wicket/apidocs/9.x/org/apache/wicket/model/IModel.html#setObject(T)

Re: WicketRuntimeException: The component(s) below failed to render. A common problem is that you have added a component in code but forgot to reference

Hi Prasanna,

Could you make a quickstart ?

[francois meillet]

you are adding the header and the footer panels in the child page but the html 
tag is in the super class.

Re: Wicket's error message-> java.lang.IllegalStateException: This container is already dequeing

[francois meillet]

There are few problems I can see (from my mobile, being on hollidays )
First you should not pass component to  PrescientTemplateOriginalPage 
constructor's argument.
Second : in the second constructor you do not add the panels to the page
Third : in the html code the header and footer tags are not presents

Re: Wicket's error message-> java.lang.IllegalStateException: This container is already dequeing

[Francois Meillet]

If what you want is redirecting the user to the Login page after the form 
submit,
you need to remove all references to the Login class in the PrescientHome 
class, 
then in the form # onSubmit you can use the code setResponsePage(Login.class).

Have a look at wicket links and wicket forms

https://ci.apache.org/projects/wicket/guide/8.x/single.html#_wicket_links

https://ci.apache.org/projects/wicket/guide/8.x/single.html#_wicket_forms

By the way you should give a try to Wicket 9 !

Hope this help

François

Application # newSession # sessionUnbound - RuntimeException

[Francois Meillet]

Hi,

Any RuntimeException thrown in Application # newSession(Request request, 
Response response) is handled by the DefaultExceptionMapper # 
mapUnexpectedExceptions(Exception e, final Application application)

but

Any RuntimeException thrown in Application # sessionUnbound(String sessionid) 
is not handled

Is that normal ?

Re: non-serializable objects to feed a DropDownChoice

[Francois Meillet]

Why don't you use a pojo that could be a simplified view of your domain class

Fast2WicketSerializer StackOverflowError

[Francois Meillet]

Hi,

I get a strange StackOverflowError with Fast2WicketSerializer

Env : Wicket version 9.0.0.M2 and previous with Fast2WicketSerializer
quickstart : https://issues.apache.org/jira/browse/WICKET-6679


When Session.get() is called in a non serialized object
and session.getMetaData(MetaDataKey) is in a serialized object
there is a StackOverflowError

Will produce a StackOverflowError
@Override
protected void onInitialize() {
super.onInitialize();

Session session = Session.get();

add(new AjaxLink("link") {

@Override
public void onClick(AjaxRequestTarget target) {

Boolean showgrid = session.getMetaData(KeyGrid);

// 
}
});
}

Will not produce StackOverflowError
@Override
protected void onInitialize() {
super.onInitialize();

add(new AjaxLink("link") {

@Override
public void onClick(AjaxRequestTarget target) {

Boolean showgrid = Session.get().getMetaData(KeyGrid);

Re: setHeaderResponseDecorator and setGatherExtendedBrowserInfo(true)

[Francois Meillet]

In the application.init() add the following line :

getResourceBundles().add(YourApplication.class, new

YourApplication.class is the {@linkplain ResourceReference#getScope() scope} of

Re: Model map with enum as a key

you are saving the value and not the key, which is why hibernate complains.

WHy not choose a DropDownBox ?

Re: Feedback panel not displaying

[Francois Meillet]

also when you call error(), you call it on your component, not on the form.
you should call it like this : 

private boolean activeSessionExist(Form form){
OCPSession session = (OCPSession)WebSession.get();

if(session.getTrackingId() != null){
log.error("Active session found. Cannot have more than one OCP tracking 
number open at a time."); 
String error = "You have an active OCP Tracking Number open 
already. "
+ "This application only allows one active OCP Tracking 
Number. "
+ "Please use the \"Exit\" button to close that 
Tracking Number before 
starting a new " + getTypeCode(); 

form.error(error);
return true;
}
return false;
}

Re: Feedback panel not displaying

[Francois Meillet]

works great for me.

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

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

FeedbackPanel feedback = new FeedbackPanel("feedback");
feedback.setOutputMarkupId(true);
form.add(feedback);

form.add(new AjaxButton("AjaxButton") {

private static final long serialVersionUID = 1L;

@Override
public void onSubmit(AjaxRequestTarget target) {
if (activeSessionExist()) {
target.add(feedback);
log.debug("Does the form have error:" + getForm().hasError());
}
}

});
}

private boolean activeSessionExist() {
error("You have an active OCP");
return true;
}



What is printed at the log.debug("Does the form have error:" + 
form.hasError());  at the first click ?

Re: Unable to retrieve row model in DataTable while running the application in Jetty

[Francois Meillet]

Hi James,

Do you use the same DataProvider for your DataTable ?
Do you use the same model when you override DataTable # IModel model(T 
object);
Do you call detach ?

AjaxClientInfoBehavior - Ajax request:SyntaxError: function statement requires a name

[Francois Meillet]

Hi,

I add an AjaxClientInfoBehavior to a page.

Sometimes I get an error.
This is very strange and I have no clue.

I have 2 computers, 1 Debian, 1 Osx, within the same network.

If I compile the code on the Osx boxe,
publish the war on a Tomcat instance running on the Osx box or on the Debian box
and I call the page with the AjaxClientInfoBehavior, 
I have the following error (in Wicket Ajax Debug)

ERROR: An error occurred while executing Ajax request:SyntaxError: function 
statement requires a name

The code in the page is

/**/


If I compile the code on the Debian box, 
publish the war on a Tomcat instance running the Debian box
I do not get any error

the code in the page is

/**/


What I see from the javascript generated : when error occurs, double quotes are 
present around the function call.

It's very weird !
Cold it be related to Sebastien'message "8.0.0-M4: org.json has issue with 
List" from Mars the 12 ?

Do you have any advice ?

Thanks
François

Re: NullPointerException on submitting a form in a modal window

[Francois Meillet]

When the RemarkForm is instancied, addButtons() is called. 
At this point the modalWindow is null.
So the modalWindow argument given to the AddRemarkButton constructor is null. 

You should modify the RemarkForm constructor to something like 
public RemarkForm(String id, ModalWindow modalWindow) {

Re: NullPointerException on submitting a form in a modal window

[Francois Meillet]

The AddRemarkButton source code you show is not the one who generated the 
exception.
The exception has been thrown line 32 in the submit method.
The source code you show has only 22 lines

Put a breakpoint in the onSubmit method.

Re: Iterate through lines from datatable with editable columns

Looks like some formcomponent (or form) validation fails.
So the model is not updated.

CsrfPreventionRequestCycleListener Link 400

[Francois Meillet]

Hi,

When I use a CsrfPreventionRequestCycleListener, clicking a Link<> while 
holding the command key does not open link in new tab.
(Wicket 8.0.0-M2 / OSX)

I get this error : 

HTTP ERROR 400
Problem accessing /. Reason: Origin does not correspond to request


Clicking a BookmarkablePageLink is ok.

bypass the FormComponent # validateRequired()

[Francois Meillet]

Hi,

I have a main form which may contain one to multiple subforms.
Subform's models have validations constraints annotations and I can't modify 
the models source code. (then I can’t remove the constraints annotations)

Each subform has 1 button.
When clicked, complete validation is done, which is fine.

The main form has 1 button.
When clicked, the main form must validate the data, but in the FormComponent # 
validate() teh use case is to bypass the FormComponent # validateRequired();

I thought I could override 
form # process(IFormSubmitter submittingComponent) in order to make all the 
formcomponents not required before the validation occurs but 
internalOnValidateModelObjects() is private.

Do you have an idea on how to do it ?

François

Twitter poll result 2

[Francois Meillet]

Hi,

Following Tobias Soloschenko thread about the Twitter poll result

I think we should focus on who who don't know Wicket.
People who don't like Wicket, the unhappy users, will not come back.

Only 34% of the respondents know what is Apache Wicket.
Put another way 66% don't ever know what is Wicket.


A) Apache Wicket's Adoption
——
Adoption (software or any good) has 2 channels : buzz and word of mouth.
For many authors word of mouth (WOM) influence 50% of the acquisition decision.

So to increase Wicket Adoption we have 2 choices : 

1) Wicket buzz) 
The buzz channel is done via articles, conferences (ApacheCon), meetup, social 
network (twitter).
The superbe Wicket's website welcome everyone who wants to adopt Wicket.

How the 50% of the 66% who don't know Wicket could be targeted ?

By increasing the buzz.
We can increase the buzz by more articles in which we could give specific 
examples where Wicket has strong value, 
write beautiful small examples to demonstrate the beauty of our beloved 
framework (this is what Vaadin has been doing since few months ), 
nice conference's coverage (ApacheCon video on youtube) 

By improving its impact using redundancy.
Mentioning Wicket'skills on dev's social network profile (linkedin) ! (very few 
do it) is one example.
By retweeting, by mentioning Wicket more often, 


2) Word of Mouth) (WOM)
Word of Mouth is the passing of information from person to person by oral 
communication (Wikipedia)
WOM is the second channel, with an equal importance for Wicket Adoption.

Word of Mouth is made of by the developers and project managers feedbacks.
A lot has been done, through a nice and complete user guide to make the 
learning curve easier.

if I think we should focus on who who don't know Wicket, I think we must hava a 
clear understanding why developers don't like Wicket.
Understanding the difficulties and dislikes is very important. And should be 
done without affect.



B) Difficulties and dislikes:
——
In many projects, developers start writing few pages, using the examples.
Most of the time developers have difficulties understanding models, and while 
trying to implement the functionalities that have to be done for yesterday,
they still do not masterise theirs models, and do not pay attention to their 
codes. 
They just do not have time for these 2 tasks. They have to deliver. Bugs will 
be fixed after.

They do copy and paste to implement first functionalities, and after few weeks, 
the code is so messy that you start thinking at the servlet / jsp … !
The style of coding we can find in the Wicket Examples is used to write ugly 
classes.
In many places I have seen pages with more than few thousand lines.

No one wants to read it before lunch time or a friday afternoon !
And as in any corporation, developers attempt to name a culprit. From outside 
the developer's corporation.
Guess what ?
This is the time Wicket starts to receive a bad reputation.
And this is where this bad reputation stops the natural spreading Wicket’ usage 
between developers, between teams in a company, between companies.
Word of mouth adoption channel is closed here.

And needless to say, when new developers arrive on this kind of existing 
project, they are not in a "wicket's loving mood".
Difficult to understand, difficult to maintain.
And you know, the first meeting is important !

We can improve a lot Wicket Examples's value by having more comments or a 
better pedagogical naming convention.
A "test yourself" page where developers can test their Wicket’s skills, with 
the correct answer and with the minimum level score to start using Wicket with 
ease, could be interresting.
But it's not good enough.

The difficulties I have found in many places are : Model, Page, Granularity
Model, Page, Granularity : from my clients, these 3 points are the "dislike's 
culprit"  : 

Models seem to be difficult to masterise, but it’s a core concept. Getting 
Models proficiency is the key.
Writing page (java code) that are well structured, have nice code, are easy to 
read should be highlighted (even if it’s more a Java skill than a Wicket’s one)
How granular should components be organized is a not an "exact science" and 
some best practices, examples could help a lot.

BootstrapPagingNavigator - Wicket-Boostrap 0.10.10 and Wicket 7.5.0

[Francois Meillet]

Wicket-Boostrap 0.10.10 and Wicket 7.5.0
When using a BootstrapPagingNavigator, I get this error : 


Last cause: The component(s) below failed to render. Possible reasons could be 
that: 1) you have added a component in code but forgot to reference it in the 
markup (thus the component will never be rendered), 2) if your components were 
added in a parent container then make sure the markup for the child container 
includes them in .

1. [Component id = pageNumber]

Re: ModalWindow.PageCreator()#createPage() is loading login page unexpectedly sometimes

[Francois Meillet]

Javadoc from Session # replaceSession() says : Call() upon login to protect 
against session fixation.

Until Wicket version 6.21 the destroy method did not set the session id to null.
In 6.23, Session # destroy() set session#id to null, this is why Login Page is 
loaded.

Hope this helps

Hi,

What is the session-timeout ?
Can you show the html page header ? and any java code that modify it.

Re: Style Sheet in page head

[Francois Meillet]

If you look at what is sent by Wicket   (open the Wicket Ajax Debug panel or 
use a debugging proxy like Charles Proxy),
you will see 












The id and type with null value are just extrapolated and added by tools 
(firebugs and so on), but are not in the html page.

Re: Style Sheet in page head

You don't define id and type so there are null.

just add id="yourid" type="text/css"

Do you use session.save(object) ?
Should be session.saveOrUpdate(object) or session.update(object)

Re: Panel.this always giving previous version of the object but not the modified one.

[Francois Meillet]

Hi,

In order to help you, you should show us the code you use for the 
MyTextFieldPanel class and the modal window content  (The PageCreator or the 
component you use).

Even better, try to do a quickstart.

Re: Is there any pointers to change the markup header of a column or propertyColumn ?

[Francois Meillet]

If you want to your own html, you need to create an object that extends 
PropertyColumn

Let's say that XXXPropertyColumn extend PropertyColumn

You need to override the populateItem(Item item, String 
componentId, IModel rowModel) method

for example

@Override
public void populateItem(Item item, String componentId, 
IModel rowModel) {
item.add(new YYYPanel(item, componentId, rowModel));
}

Then you create the YYYPanel.java and the html file 
XXXPropertyColumn$YYYPanel.html with your own design.

Re: Wicket model problem

[Francois Meillet]

You can also use a IDetachListener to check that no one LDM (field) is attached 
after the page#detach() has been called. 

In the Application#init() you can add

getFrameworkSettings().setDetachListener(

new IDetachListener() {

@Override
public void onDetach(Component component) {

for (Field field : 
component.getClass().getDeclaredFields()) {
field.setAccessible(true);

Class theClass = field.getType();
if 
(LoadableDetachableModel.class.isAssignableFrom(theClass)) {

try {
if (((LoadableDetachableModel) 
field.get(component)).isAttached()) {
System.err.println("warning: component:" + 
component.getClass().getName() + " / " + field.getName() + " is attached");
}
}
//
catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
}

@Override
public void onDestroyListener() {

}
}
);

Re: JsonRequestLogger --> JsonMappingException --> StackOverflowError Infinite recursion

[Francois Meillet]

Before the 7.0.0 release, wicket-extension used 

org.codehaus.jackson
jackson-mapper-asl
1.8.5

So no change can be done.


7.0.0, 7.1.0 and 7.2.0 use

com.fasterxml.jackson.core
jackson-databind
2.4.1.3



JacksonAnnotationIntrospector 

/**
 * @deprecated (since 2.3) Use {@link #findFilterId(Annotated)} instead
 */
@Deprecated
@Override
public Object findFilterId(AnnotatedClass ac) {
return _findFilterId(ac);
}

@Override
public Object findFilterId(Annotated a) {
return _findFilterId(a);
}

so the findFilterId(Annotated a) can be used in the JsonRequestLogger # 
FilteredIntrospector


findFilterId(AnnotatedClass ac) has been removed from the 2.7 release.


The sole Wicket' class using Jackson I found is JacksonAnnotationIntrospector,
so using Jackson 2.7.1 release can be done.
Tested. ok.

Re: JsonRequestLogger --> JsonMappingException --> StackOverflowError Infinite recursion

[Francois Meillet]

Hi Martin,

Jackson JacksonAnnotationIntrospector # findFilterId() method signature has 
been changed

from findFilterId(AnnotatedClass ac) to findFilterId(Annotated a) 


in the JsonRequestLogger, changing this  

private static final class FilteredIntrospector extends 
JacksonAnnotationIntrospector
{
@Override
public Object findFilterId(AnnotatedClass ac)
{
return "default";
}
}   
   
   
to that resolved the problem

private static final class FilteredIntrospector extends 
JacksonAnnotationIntrospector
{
@Override
public Object findFilterId(Annotated a) 
{
return "default";
}
}
