Thanks a lot for this tip, it worked like a charm. I learned something
new about Wicket; that's always a good thing. :-)
When I did read "Listener" in the classe name, I associated it with
some callback or event hook on the server side -- seems, that I need
to pay more attention to the AJAX mechanisms, how they work.
Cheers,
Joachim

One button in a form shall show result in new tab
Hi,
I'm tasked with upgrading an application from Wicket 7 to Wicket 9.
There is one class with a heavy code smell: it relies on a Wicket
internal realization. (Which promptly doesn't work any more in Wicket
9...) This email is part of my search for a better realization method.
The use case:
-- There is a form with lots of submit buttons.
-- One button realizes a "show as pdf" functionality.
-- The PDF shall be shown in a new tab.
-- It shall be possible to use the button while still working on
the form. This is a form submit -- the PDF shall show the then
current content of the page. (Validation is not an issue in
this case, the submit and form processing will succeed.)
-- After showing a PDF representation of the form, it shall be
possible to use the other buttons in this form, which are part of
the HTML sequence of pages.
I cannot use Javascript popups, as too many browsers block them. (In
fact, my own developer browser blocks them. ;-)) So I need to have the
following functionality for this button:
-- Before the submit, a target attribute "_blank" get's added to the
form.
-- The form is submittet, by this button. (I.e., its onSubmit() must
be called.)
-- Afterwards, the target attribute is deleted from the form.
The previous programmer in this project simply copied the Javascript
code for an AjaxSubmitLink from Wicket 7 and enriched it with
adding/deleting the form attribute. Not the smartest move, indeed; but
it was working all this time
I'm looking for best practice to achieve that functionality with the
available Wicket API. I.e., I want to prepend and append Javascript to
the Wicket-supplied submit functionality of a button or ajax submit
action. I have looked at Javadoc and source code of the following
classes (and their superclasses) and didn't found any hook/method
where I can achieve my desired result:
-- AjaxRequestAttributes: No methods to prepend/append JS code.
-- AjaxSubmitLink: No methods to manipulate the emmitted JS code.
-- AjaxFormSubmitBehavior: No methods to manipulate the emmitted JS
code.
-- Button: has getOnClickScript(), but this is empty.
-- AjaxButton: doesn't redefine getOnClickScript(), so no gain to be
get here either.
FWIW: The application uses getCspSettings().blocking().disabled().
There's too much JS code in HTML that I don't want to touch in this
round of update; that's a step after the Wicket 9 migration. Thus,
currently I have no qualms to add JS code to HTML "onsubmit"
attributes if that's the way to go at the moment.
I'm looking for something like #prependJavaScript() and
#appendJavaScript() in AjaxRequestTarget -- but not in the response
handling, instead for the code that triggers the click event.
tl;dr: How can I specify JS code that's executed before and after a
(specific) button or ajax submit of a form?
Here's hoping for some tips,
Joachim

Add
@Override
protected void onRender () {
IMarkupSettings markupSettings =
Application.get().getMarkupSettings();
boolean stripWicketTags =
markupSettings.getStripWicketTags();
markupSettings.setStripWicketTags(true);
super.onRender();
markupSettings.setStripWicketTags(stripWicketTags);
}
with an appropriate Javadoc to your respective classes. (I changed
line breaks to fit in 70 columns.)

I get that I can define my own event classes server-side. I don't get how that helps me client side. My problem is: How do I communicate to client-side within an event handler that attrs.event.preventDefault() shall be called for exactly that event handler or not. Wicket provides a static pre-made decision via AjaxRequestAttributes; I want a dynamic one. I looked at the code you cited, and the enable/disable decision is done server-side, right? But how does introduction of a new event type help with my problem client-side? Adding the links to ART on some event won't change anything, as this won't influence the _original DOM event_ (attrs.event) that controls if default action is taken or not. I also can't see how that new Wicket event type would give me access to that DOM event I want to influence. Sorry, but I don't get it. Maybe your Wicket usage is way above my head? Or, do you mean that the server shall decide, according to previous user actions, that the link is enabled from now on and then shall change the link in an ART? Also disabling it back, as needed? That's hard to do, some parameter for the enable/disable decision are external availability of resources that are checked at the moment of link activation. (The actual link almost always works. The behavior shall implement proper error checking and reporting in case of unavailable resources or other errors that are beyond the user's realm.)

The link in question delivers a PDF document, and has target="_blank" to do that in a new tab. In fact, there are several of these links, and only some of that have the controlling behavior. Thus prevention of the default action is essential, to prevent opening a new tab. I also had a solution that used window.open() in JS -- but that code wasn't any prettier. I think what I'm looking for is a way to add some client data to an ART target that I can access client-side, e.g., in an AJAX call listener.

Hi, I have a class of links where some of them sometimes shall not trigger. The decision is made server-side according to current state. At first sight, the realization seems to be not that straight forward: -- I add an AJAX behavior to these link that allows default action and computes if the link action shall be prevented. -- The AJAX behavior has an AJAX call listener (complete handler) that may call attrs.event.preventDefault() if the link shall not be triggered. -- The decision if the link shall not be triggered is communicated by the AJAX request to the complete handler via an HiddenField that is updated in the AJAX request.

Form-Validators and invisible form components
Hi, I have a form with a date input that may be invisible. If it is visible, its value must be after another date input's value. I established a FormValidator that checks that condition. It knows about the potential invisibility and handles it. Now, for most pages Wicket outputs the warning IFormValidator in form `form` depends on a component that has been removed from the page or is no longer visible. Offending component id `inhaber1.arbeitSeit`. I thought about disabling the FormValidator if its dependent component is invisible -- but then I realized that isEnabled() of validator-behaviors is not checked and that's not the route to go. FWIW, I think that's a mis-feature. Form.validateFormValidator(IFormValidator) should check isEnabled(). Checking isEnabled() also in FormComponent.validateValidators() is a different question, I can't find a use case for it. Thus, my question: how may I realize checks over several form components where one of them may be invisible?

Re: Best practice sought: Register client change at server
I didn't know that I can introduce my own event names, I thought I
had to use one of the pre-defined ones.
Thanks for that enlightenment, it works like a charm.

Interesting to hear; I'd have thought that works. Tricky thing,
that. As I wrote, I didn't try the code; I just copied the access
to HttpSession from the posts below.
But, since wicketSession.bind() is final, one cannot subclass
Session and redefine it either, to set the timeout there. (Much too
many methods of Wicket classes are final, without really good
reason; I copy them to my applications making the methods non-final
much too often. :-( )
Martin, what would you propose to be the hook that allows to
establish a different session timeout application-wide within your
Java application? I hadn't had yet that case, web.xml suffices by
now, but it would be good to know for the future.

You have to redefine WebApplication#newSession().
It can't be done in init(), as no session exists yet. And you must
set the Session timeout for each new session anew.
Without having tried it, code like
@Override
public Session newSession(Request request, Response response) {
Session session = super.newSession(request, response);
((ServletWebRequest)request).getContainerRequest().getSession().setMaxInactiveInterval(TIMEOUT);
return session;
}
should work. Maybe check that request is really a
ServletWebRequest. (This is also a good place to set the locale.)

Why don't you construct it with an empty model object, i.e., with
new Model()? Then the CPM from the panel is not accessed.

And the rest of the thread tracks the problem that that's not the

If you've got CSS predefined and can't change it, there's the
callback method onDisable(ComponentTag) on your form components
that can be overriden to change CSS class of the emittet markup.

Information about that is found is in Eclipse's console.
(I assume a barbone log4j configuration or similar.)
E.g., from some start this morning, log records output only simple class names:
10:58:09,184 INFO ContextLoader - Root WebApplicationContext: initialization
started
10:58:09,297 INFO XmlBeanDefinitionReader - Loading XML bean definitions from
ServletContext resource [/WEB-INF/applicationContext.xml]
If a log record like the last one is output, your applicationContext.xml is
found.
If not: with your configuration, you need to place it in src/main/resources.
Without a contextConfigLocation, it must be placed in src/main/webapp/WEB-INF.
(Standard Maven dir structure assumed.)
When you get a log record about the applicationContext.xml read in,
there should be another one from class DefaultListableBeanFactory that
tells which beans got instantiated. Your bean

Btw, your class FrontOfficeApp is a subclass of WebApplication, isn't it?

That's not relevant; the error happens before.
The startup code looks for a Spring bean that's a class or subclass of
WebApplication
and doesn't find one.

Michael Chandler wrote:

Then you probably don't use wicket-spring. Or you store your app
context in a Wicket component, e.g., a page.
The "official" documentation is
https://cwiki.apache.org/confluence/display/WICKET/spring.html
IMHO it's problematic because it tells you first about things you don't want to
use.
There's a chapter in the new free Wicket guide, but it's very basic as well.
So, here's my method / recommendation:
1. I use Maven. One needs a dependency to org.apache.wicket:wicket-spring.
2. My application object is a Spring Bean. It's declared in
WEB-INF/applicationContext.xml. web.xml tells about it
Load WebApplicationContext of Spring from WEB-INF/applicationContext.xml.
org.springframework.web.context.ContextLoaderListener
Wicket Application Filter
org.apache.wicket.protocol.http.WicketFilter
applicationFactoryClassName
org.apache.wicket.spring.SpringWebApplicationFactory
ignorePaths
/js,/css,/images
(Adapt your ignorePaths as needed.)
3. Within your application object, you need to call
this.getComponentInstantiationListeners().add(new
SpringComponentInjector(this));
Usually, it's sufficient to call that in init().
Except if you're using converters that need access to Spring beans,
e.g., services. Then, newConverterLocator() is a better place for it.
4. Within your Wicket components, tag Spring beans with an annotation:
@SpringBean BeanClass beanObject;
Wicket will inject the Spring bean. Of course, you need to *declare*
your Spring bean in Spring! I.e., you either need to declare an
application-level bean in WEB-INF/applicationContext.xml or you need
to trigger annotation scanning by Spring. (
and friends.)
5. If you need Spring beans in a behavior, resource, or any other non-component
class, you need to tell Wicket about it. For that, you call
Injector.get().inject(this);
in that class' constructor. Afterwards, @SpringBean injections
work in that class.
That's all. It just works.
HTH,
Joachim

That is a common problem if the document is requested by HTTPS and not by HTTP, and if in IE the preference "Don't store encrypted pages" is not set. (The exact preference name is different; I don't have an IE with English user interface available.) This behavior of IE is very obscure -- one would think that the ability to store encrypted pages would be enough to show them. If that's the case, one needs to change the caching headers. Per Default, for a generated ByteArrayResource (and PDF-Downloads are often implemented as such) the header Cache-Control: no-cache, must-revalidate is generated. That must be changed. In my experience, just discarding the Cache-Control header suffices. In Wicket 6.x that's done by overriding configureCache(). According to http://stackoverflow.com/questions/1038707/cant-display-pdf-from-https-in-ie-8-on-64-bit-vista one should instead use the header Cache-Control: private and also maybe Accept-Ranges: none For dynamically generated PDF resources the latter ususally doesn't make sense, IMO.

According to your code, your "business model" is a list of QuestionBO objects.
Each QuestionBO object seems to have a property with the question and a
property for the answer. For the sake of this example, let's assume
public class QuestionBO {
private String question;
private ReplyOptionBO answer;
}
(Add serializability and other methods as needed.) That your answer is of
this class follows from your DropDownChoice declaration below.
You'll pass a Wicket model of the list where you want to store the answer to the
constructor. If that business model object gets passed to your page, just wrap
it.
Otherwise, if it's a property of your page, use something like
form.add(new QuestionListView("wicket_id", PropertyModel.of(this,
"propName"))
If it's a member of a larger business model object that's get used elsewhere
in this form as well, chomp the 2nd argument and establish the larger object
in a CPM at the form or page level.

My tip: change to extends PropertyListView
if you start working with ListViews. Explore more elaborate model bindings
when you have more experience.
This establishs a CPM for every list item, you'll be able to access
the object properties directly, and don't have to spell out models
explicitly.

This code doesn't make much sense to me.
Is QuestionBO.TEXT a constant that's the name of the property with the question
text?
Anyhow, with the above change, this is just
item.add(new Label ("question"))
The label will get it's object from the CPM that's established by PLV.

This changes to
item.add(new DropDownChoice("answer", choices,
renderer)
Again, the DropDownChoice will get it's answer property via the CPM
and will just store the answer object in the respective property
of the respective list element object.
In case your question object list change a lot while the application runs,
establish the DB id as selection id in your choice renderer; instead of
the index number.

If your answer shall not be stored in the question object, or if it's also
not possible to have a class that combines question and answer in one object,
it get's a bit more difficult. Then you have to pass a model of a list of answer
objects to the constructor as well, and store that in the ListView, to be able
to access the answer objects in a model in your DropDownChoice. That can be
done,
e.g., with a subclass of PropertyModel that references this.answerListModel,
knows the list item index, and has appropriate redefinitions for getObject()
and setObject() that do the list access.

When you use wicket-spring, that's the case, for example. You can tell Eclipse that it shall get the Spring jars from your Spring project, then. In your Web project properties, in `Project references'. The Spring jars and all dependent jars must be marked as exported in your Spring projects Java Build Path. But note that in the end, Eclipse will deploy all these jars to the WEB-INF/lib directory of your Tomcat working directory (usually .metadata/.plugins/org.eclipse.wst.server.core/tmp*/wtpwebapps/ in your workspace directory).

Have you confirmed that the cookie store is updated on AJAX
requests? (a) are the updated cookies sent, and (b) are they made
available properly for your app code; i.e., don't use some
previously cached values?
I'd wireshark the request and then step through the cookie
gathering code to check what values are sent in the AJAX request
and where the load() method gets its values from.

I.e., you told Raul that he should set the FormComponentPanel's model. And then he risks getting null values set in his model at the panel level. Please note, that I don't argue for or against storing CompountPropertyModels in FormComponetPanels. I have many places in my applications where storing models is sensible and where the form's CompountPropertyModel is not the right thing, design-wise. And the other way round, too. As a common use case, consider when a FormComponentPanel is actually a reusable model that may be used in several situations. A recent example of mine is a component that handles address input and validation for a person. The base model, available as a CompountPropertyModel at form level, has several persons. So the FormComponentPanel gets passed the right person model (actually, the address model from that person model -- a person might have several addresses!) and uses it. And in such cases, one has to take care that the FormComponent processing lifecycle is properly adapted to such situation. > Who will perform the conversion then? As I've written, quite often it's not the conversion that's the problem, but the updateModel() call that stores FormComponent.convertedInput into the model object. To repeat: On the panel level, no input is available, and convertInput() stores that as null in FormComponent.convertedInput. You need to prevent usage of that stored field in updateModel(), otherwise your model object will end up to be null. Overriding convertInput() is of no use here, if there *is no input* that can be converted. Thus quite clearly, overriding FormComponentPanel#convertInput() is only sensible if you do something with the input values of sub-components, beyond storing them, and if you can compute something that you can place into convertedInput. If it's just about storing and you use a CompountPropertyModel, overriding FormComponentPanel#updateModel() is adequate and sufficient. I hope this makes my arguments clearer. It probably won't help Raul, though. :-( Joachim -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Joachim Schrod, Roedermark, Germany Email: jsch...@acm.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Really? That's not possible in an 1.4-based application, IMHO. FormComponentPanel is a FormComponent, i.e., it participates in conversion, validation, and update Model. When that FormComponentPanel has an associated model, e.g., a CompoundPropertyModel, its getInputAsArray() will return null, null will be stored as convertedInput, and updateModel() will set the CompoundPropertyModel's object to that null value. When sub-widgets of a FormComponentPanel do all the work necessary, and the FormComponentPanel has a model of its own, I often override updateModel() to be an empty method, to prevent the behavior named above from happening.

Did you try to use PropertyModels of your account object, maybe a
CompoundPropertyModel instead of setting the TextField's model
objects in the constructor that way?

Have you tried to use a resource link with
a) an AJAX action to update your page
b) a Call-Decorator that adds "return true" to the onclick-Event.
That causes the genuine Resource-Link-Action to be done which
initiate a download.
c) Maybe also use target="_blank" in your Link-HTML. If there are
errors in your download code, you can arrange to show them in a
new situation-specific error page.
Something like:
final ResourceLink downloadPDF = new
ResourceLink("downloadPDF", pdfResource);
downloadPDF.add(new AjaxEventBehavior ("onclick") {
private static final long serialVersionUID = 1L;
@Override protected void onEvent (AjaxRequestTarget target) {
// update actions for page go here
}
@Override protected IAjaxCallDecorator getAjaxCallDecorator() {
return new AjaxCallDecorator() {
private static final long serialVersionUID = 1L;
@Override public CharSequence decorateScript(CharSequence script) {
return script+"return true;";
}
};
}
});
This is working 1.4 code (it has to run on JBoss 4, I can't use 1.5ff),
no problems with IE8. (pdfResource is a WebResource-subclass object that
actually generates a PDF document.) IAjaxCallDecorator is gone in Wicket 6,
but there is a replacement for it; that was mentioned on this list
recently.

That feedbackPanelINFO is set both on li and on span.
In my current project, CSS styling is not done by us, but by a
designer and is shared over several projects, most of them who
don't use Wicket. The CSS styling is just for feedbackPanelINFO,
not for li.feedbackPanelINFO.
AFAIU, similar problems appear in portlet situations, or in other
situations where you don't control CSS fully. As Alec mentions,
Twitter bootstrap is an other example.
Btw, I never wrote that this is a "big" design problem. I just say
that IMHO it's an existing one that goes beyond a single project.
The standard way we cope in our projects is a more-or-less empty
FeedbackPanel subclass with replaced HTML. Not pretty, as we ignore
module boundaries for wicket identifiers; but the alternative --
copying the complete code of FeedbackPanel to a project specific
class -- wouldn't be good either.

That a CSS class applies both to LI and to below-SPAN element, is clearly not appropriate for almost all situations. The proposed change even keeps that, for backward-compatibility. Of course, one can subclass FeedbackPanel and sustitute the HTML code. We do it in all projects. But this is a workaround for a bug in Wicket's HTML/CSS/interface design, and not a to-be-continued asset.

Re: How to control IMG/CSS URL-Rewriting in mounted pages?
Well, one answer yet, with an assertion that Wicket does what I
don't want it to do. :-(
So, is it really not possible to exchange bidirectionally HTML
files with an HTML designer who does *not* put all his HTML files
in web root? I thought being able to share files bidirectionally
with HTML designers was one of the major selling points of Wicket?!
I assume nobody has the energy to really look at my issue. Would it
help if I put up a minimal example project for download that shows
my problem? Anybody willing to look then at it?
I don't need a full solution. An hint like "class X does the URL
rewriting for images" would be most welcome, overwriting that
behavior with appropriate subclassing is something I can well do on
my own.
Best,
Joachim

IMO, this call is wrong. It should be
String parts[] = Strings.split(qp, '=', 2);
I'd file a bug and patch the code locally.

Re: How to control IMG/CSS URL-Rewriting in mounted pages?
Yes, that's what I observed and described below. And that behavior is not appropriate for my use case. So, how can I stop Wicket to "make the url relative to the web root no matter what mount path I use for the page"? I want to *change* that: my designer delivers HTML where the images are *not* relative to the web root, but to one directory below. In our HTML files are URLs like "../images/image.img" and I don't want to change these URLs. Alternatively, how can I tell Wicket that the web root has a different prefix just for rewriting these image URLs?

I'm new to Wicket, but it seems obvious that this is impossible. The application object exists outside of resp. independent of any servlet requests. Only Web pages and their components are concercened with HTTP requests, and thus only they have access. If you want to store or access something from a request in your application object -- which is a singleton that's independent from any request and any session, then there's probably something wrong with your design.
