And the question is, I guess, why ?
A: Because Wicket makes a check that the HTML element that triggers the JS
event and the form to be submitted are in the DOM document. I suppose there
are several links with the same markup id - LNKDETALLE_A_null.

Wicket 1.4.x - AjaxSubmitLink doesn't work

[anotherUser]

Hi this my first post here, let's see my problem:
i am adding a AjaxSubmitLink in a Listview like this:

AjaxSubmitLink lnkAgregar = new AjaxSubmitLink("lnkDetalle", form) {

 @Override
 protected void onSubmit(AjaxRequestTarget art, Form form) {

 }
   };
lnkAgregar.setMarkupId("LNKDETALLE_A_" + fDetalle.getId());

when i tried to click this link 
Wicket Ajax Debug Windows show me:
NFO: Ajax POST stopped because of precondition check,
url:?wicket:interface=:3:templateCircuitoFirmasForm:containerLW:lwTemplateFirmasDetalle:1:lnkAgregarDetalle::IActivePageBehaviorListener:0:-1&wicket:ignoreIfNotActive=true

This was because, fDetalle.getId() was null, i comment this line and resolve
the problem
lnkAgregar.setMarkupId("LNKDETALLE_A_" + fDetalle.getId());

AbstractAjaxTimerBehavior and setInterval and clearInterval

[infiniter]

I created a very similar class to AbstractAjaxTimerBehavior, with the
difference that I'm using setInterval instead of setTimeOut in
#getJsTimeoutCall and I'm assigning a variable name to it, so that I can use
the clearInterval in #getFailureScript , the problem I got is that in the
response envelope I'm getting the script in #getJsTimeoutCall back, which is
inside the  block, and I don't want that because when the
setInterval is set again the value in the variable changes therefore I
cannot clear the interval and also it makes the response heavier.

So basically I just want the script in #getJsTimeoutCall executed only once
just to start the interval. I tried to make the response not return the
"evaluate" block,  but I was unsuccessful.

Re: check load

No, Wicket cannot tell you such information.
Consult AWS documentation.

Re: send message from modal window to parent

[Paul Bors]

If I understand you right you want to close your parent window from inside
the modal pop-up window.
I take it you want them both closed.

Won't it be simpler to send the window JS object to your pop-up and call
the window.close() from inside your pop-up?

Re: Proper models approach

[Paul Bors]

Why not use the existing Wicket Wizard already?
See the live examples at:
http://www.wicket-library.com/wicket-examples/wizard/;jsessionid=25DD01023009791E13E212292E4150D1?0

I think I used a combination of models depending on the panel shown. In the
end they all updated a single model.

Re: Ajax Behavior not working after 1 time

[eugenebalt]

Martin, we're already doing setOutputMarkupId(true) on both dropdowns. Is
that one different from OutputMarkupId?

Ajax Behavior not working after 1 time

[eugenebalt]

We have a DropDown whose selection affects the 2nd DropDown (hide+disable).

This is done in Ajax "onchange" on the 1st DropDown, very simple. In the
Ajax behavior, we specify

if (condition)
{
   choice2.setEnabled(false); choice2.setEnabled(false);
target.addComponent(choice2);
}
else
{
   choice2.setEnabled(true); choice2.setEnabled(true);
target.addComponent(choice2);
}

We verified that our condition works, and Ajax kicks in correctly on every
change in DropDown #1, and the hide/show works the *first* time.

Afterwards, after switching back and trying again, we are no longer able to
show Choice2. It always stays hidden, and the correct condition is
activated, but the dropdown isn't updated for some reason.

Any ideas? We're doing target.addComponent() in both cases.

Draft-mode validation

[pureza]

Hi,

I have a very big form with two buttons: Save and Submit. If the user hits
the Save button, I want to bypass *some* of the validation, but not all of
it. For example, I want to notify the user of any conversion errors (such as
text in a field where a number is expected), but I want to ignore required
fields.

This article
(http://www.richardnichols.net/2010/10/implementing-a-draft-mode-with-apache-wicket-forms/)
suggests a way of doing this, but my problem is that my form is really big
and includes many sub-forms. How can a sub-form know if we are in draft-mode
validation? Is there a nice way of defining application-wide validation
settings?

Thanks,

Luis Pureza

Re: Some Validators Not Kicking In

[eugenebalt]

Sorry to keep posting, but does order matter? We're adding the validators in
all kinds of order.

Sometimes, we have a field that shows messages associated with itself, AND
its Form-level validator. But that doesn't work for other fields, which
don't show the Form-associated validator.

Re: Some Validators Not Kicking In

[eugenebalt]

So if I have something wrong with my field (by itself), than any Form
validators that involve it as well, won't kick in?

>From the documentation:
These validators are added to the form and only executed if all form
components returned by getDependentFormComponents() have been successfully
validated before this validator runs. 

What if I need to show all messages, both "solo" and Form-level?

Re: Some Validators Not Kicking In

[eugenebalt]

That may be it. The Form-level ones are the ones not executing sometimes.

So to check if it's invalid, I just see if getDependentComponents() returns
NULL? And what could cause it to be NULL, if I'm specifying the right valid
components that exist on the form?

Thanks again

Re: wicket:for behavior

[Igor Vaynberg]

wicket:for cant set output markup id because it comes after the form
component in markup and so the form component has already been
rendered. it already sets the output of markup, but it only helps if
the label is before the component in markup.

Re: Serialization of DAO

[Stephen Walsh]

Thanks, Martin.  I intialize here, (which I just realized is not the best
spot):

private void setUpMongo() {
mongo = MongoUtil.getMongo();
morphia = new Morphia().map(Blog.class).map(Person.class);
blogDAO = new BlogDAO(mongo, morphia);
}

I am using the Wicket Guice module, and I think your second point is what I
was getting at.  From learning about Guice (
http://www.youtube.com/watch?feature=player_embedded&v=hBVJbzAagfs), I
thought the point was to initialize once and then reuse wherever needed.  I
figured initialization would happen in the application class.  Maybe I'm
misunderstanding.  If it's supposed to happen in the application class,
then I don't really have need for a module because I don't have an
interface in this case, right?

Thanks for the help on this.

Re: Some Validators Not Kicking In

Hi,

Looking at org.apache.wicket.markup.html.form.Form#validateFormValidator I
see that form validator will be skipped if any of its
org.apache.wicket.markup.html.form.validation.IFormValidator#getDependentFormComponents
is already invalid.

Some Validators Not Kicking In

[eugenebalt]

We're having an issue where some of our validators aren't kicking in.

A bunch of Component- and Form-level validators are added in the page
constructor. We have output statements in each. The output shows that in
some situations some of the validators are "short-circuited" and don't get
executed even though we've added them. Any ideas?

Re: Wicket 6: LinkResource with a dynamic resource

[dpmihai]

The only solution I have is to create my own class ResourceLink with a
method:

public void beforeResourceRequested() {}  (here I will set rowModel to
my resource)


and use it inside onResourceRequested:

/**
 * @see org.apache.wicket.IResourceListener#onResourceRequested()
 */
@Override
public final void onResourceRequested()
{
beforeResourceRequested();
Attributes a = new Attributes(RequestCycle.get().getRequest(),
RequestCycle.get()
.getResponse(), null);
resource.respond(a);
onLinkClicked();
}

Wicket 6: LinkResource with a dynamic resource

[dpmihai]

Hi.

I want to have a table with a Link PropertyColumn which contains a
LinkResource. When user clicks on the link I want to be able to pass the row
model to resource first and then have the resource loaded.

I created a ResourceLinkPropertyColumn class like:


public class ResourceLinkPropertyColumn extends PropertyColumn
{

private IModel labelModel;
private ByteArrayResource resource;

public ResourceLinkPropertyColumn(IModel displayModel, IModel
labelModel, ByteArrayResource resource) {
super(displayModel, null);
this.labelModel = labelModel;
this.resource = resource;
}

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

 protected void onDone(IModel rowModel) {
 }

 public ByteArrayResource getResource() {
return resource;
 }

 public class LinkPanel extends Panel { 

public LinkPanel(final Item item, final String componentId, 
final IModel
model) {
super(componentId);

ResourceLink link = new ResourceLink("link", resource) {

@Override
public void onClick() {
onDone(model);
super.onClick();
}

protected void onComponentTag(ComponentTag 
componentTag) {
 super.onComponentTag(componentTag);
 componentTag.put("target", "_blank");
}


};
add(link);

IModel tmpLabelModel = labelModel;
if (labelModel == null) {
tmpLabelModel = getDataModel(model);
}

link.add(new Label("label", tmpLabelModel));
}
}
}

When I create my data table I add my column like:

columns.add(new ResourceLinkPropertyColumn(new
Model("Generate"), new Model("Generate"),new
MyByteArrayResource()) {
protected void onDone(IModel rowModel) {  
final MyObject object = rowModel.getObject();   

((MyByteArrayResource)getResource()).setMyObject(object);
}
});   

The problem is that when I click the link the resource is loaded first and
then my onDone method is called.
Is there any possibility to pass the model to the resource before it is
loaded?

Re: Wicket Atmosphere with CryptoMapper gives exception.

[Martin Grigorov]

Hi,

I think you should ask in Atmosphere mailing list.
The servlet mapping is on /* so I'm not sure why Atmosphere rejects the
request to /A7-TzylrsD0NeLU_GE2Phg/A7-56.
IMO it should accept and pass it to WicketFilter where the request path
will be decrypted and processed.

Wicket Guide (Was: RSS)

[Martin Grigorov]

Thanks for sharing, Andrea!

In what format will be your guide ?
I see you have many demo applications but is there any kind of
documentation explaining what they actually show ?

I'm a bit slow lately on the Reference Guide initiative :-/

 changes

 I can generate my xml file, but not really sure how to go about actually
 publishing it and having Wicket recognize it as a resource once it's on
 the
 file system.  Hope that makes sense...

Re: how to setup call context for every request

[Tom Eicher]

Reposting to the list (sorry Martin ;-) in hope for
feedback on @RequestScoped Wicket-CDI vs EJB... :


[...about seeting up stuff to propagate user/session/JAAS
info from the wicket web layer to a JBoss AS7 EJB...]

You can use IRequestCycleListener#onBeginRequest().


Thanks for the suggestion - but I just put the whole JAAS idea in
the bin, it's just too much crappy and proprietary code for what
it's worth.

Now, I just built my own @SessionScoped "call context" in the
web layer (Wicket WebPage constructor), and check it with a standard
default EJB interceptor at the ejb layer (which @Inject's the "call
context").

Since I used SessionScoped, not RequestScoped, all calls in-between
the page class (which sets the "call context") like AJAX, onClick()s
etc still have the instance from the previous "full page request"
available.

Is there anything fundamentally wrong with my approach ?
Any security issues, race conditions, threadsafety, ... ?

There is not too much current info about using Wicket with the
lesser known CDI/Weld scope stuff around ...
...@RequestScoped is supposed to work for
Wicket6/wicket-cdi-6.4/Tomcat7, right ?

(And looks ok, but not heavily concurrently tested of course...)

Cheers, Tom.

You are probably correct.

With such markup there is no need of wicket:for at all.

Image.initModel() returns null and forbids attaching an image to a form CompoundPropertyModel - why?

[Marios Skounakis]

Hi all,

I have created a component that extends NonCachingImage which overrides
getImageResource(). The intent was to include this in a form, and retrieve
the image data from a property of the form object.

However this does not work because Image.initModel() returns null and as a
result my component does not get an AttachedPropertyModel.

If I override initModel in my component and replicate the code from
Component.initModel it work perfectly. But this is ugly (duplicate code,
etc).

So, any suggestions?

Thanks in advance,
Marios

Re: wicket:for behavior

[Bas Gooren]

We're still on wicket 1.5, so I don't know if this still applies in 6.x, 
but the reason for this is that the wicket:for handler is executed in 
the same order as your html.


That means that, since your wicket:for is after the input itself, 
calling setOutputMarkupId() on it no longer has any effect during that 
render.


The solution is quite simple: wrap the input in the label:






In this scenario the wicket:for is always handled before the input.

Met vriendelijke groet,
Kind regards,

Bas Gooren

the resulting HTML is:

and label for is not working :(

Am I using this feature improperly?
Wicket 6.6.0 is used

Thanks in advance

Re: wicket:for behavior

[Martin Grigorov]

Hi,

Try with : textField.setOutputMarkupId(true).
If this helps please file a ticket - 'wicket:for' should do this for you.

[Martin Grigorov]

Hi Tom,

Please post to the mailing lists. The chance to get an answer is bigger ;-)

Check Igor's series about Wicket-CDI at
https://www.42lines.net/category/blog/software-engineering/
You may need the conversation scope.

Re: Serialization of DAO

[Martin Grigorov]

Hi,

I don't see how you initialize blogDAO. If you don't use wicket-ioc module
then you will need to lookup the DAO from the application whenever you need
it:

public void onSubmit() {

  BlogDAO blogDao = MyApplication.get().getBlogDAO();
  blogDao.save(blog);
}
This way you wont keep reference to it in the page/component and it wont be
serialized.

If you use wicket-guice module then you can do:

@Inject
private  BlogDAO blogDao;

and use it anywhere.
Wicket will use Guice to lookup the bean at component creation but the bean
will be wrapped in a serializable proxy. That is a lightweight proxy will
be (de)serialized with the page.
This is the recommended way.
wicket-string works the same way.
wicket-cdi leaves the proxy creation to the CDI implementation.
