Re: WebApplication.get().getSharedResources.remove()
can i ask why are you dismounting?
create your resourcereference that returns your resource,use
resourcereference for mounting
and Key key =new Key(your ResourceReference)
you should also read a very nice martin-g's article on how to mount
resources in wicket 1.5

WebApplication.get().getSharedResources.remove()
Hi folks,
in 1.4 I was doing (pseudo code, real code is longer):
public class MyPage extends WebPage
{
public MyPage()
{
...
DynamicImageResource image = new DynamicImageResource();
image.setImageData(_my_generated_byte_array_);
...
MyApp.get().getSharedResources().remove("/my/custom/resource.jpg");
MyApp.get().getSharedResources().add("/my/custom/resource_new",
image);
...
}
}
Not know if it's optimal but it works and resources are dynamicaly
mounted and dismounted.
In 1.5 I can't do:
MyApp.get().getSharedResources().remove("/my/custom/resource.jpg");
because remove() method in 1.5 needs "ResourceReference.Key"
Is there example how to work with remove() in 1.5 or how to rewrite
my code in example above?
Thanks,
JT

Convert wicket ajax posts do wicket ajax get requests
I am having issues with IE and ajax post requests.
The issue is reported here:
http://support.microsoft.com/kb/895954
As a way to address the issue, I was thinking of addressing the
application. There are several places with ajax post requests. I was
trying to see if I can convert those requests to wicket ajax gets
requests.
I am talking about radio buttons and onchange drop down boxes.
In this behavior, how would I make a change to use wicketAjaxGet and
keep the general functionality?
public abstract class AjaxFormChoiceComponentUpdatingBehavior extends
AbstractDefaultAjaxBehavior:
protected final CharSequence getEventHandler()
{
return generateCallbackScript(new
AppendingStringBuffer("wicketAjaxPost('").append(
getCallbackUrl()).append(
"', wicketSerializeForm(document.getElementById('" +
getComponent().getMarkupId() +
"',false))"));
}

RE: ConcurrentModificationException
I noticed that there are only two types of exceptions handled by this handler
so far:
1. WicketRuntimeException : Method onFormSubmitted of interface
org.apache.wicket.markup.html.form.IFormSubmitListener targeted at [SearchForm
[Component id = search_form]] on component [SearchForm [Component id =
search_form]] threw an exception
2. org.apache.wicket.request.mapper.StalePageException
Could an expired session be the underline cause for both cases?

It is called before. This is the place where your app can handle the problem.
If this method return null then Wicket falls back to the default handling of
exceptions (see DefaultExceptionMapper).
But in your case you always redirect to another page - ERROR_PAGE_URL.

RE: ConcurrentModificationException
I have been trying to reproduce it on our dev server this morning, but could
not. However I did run into it twice on our production server yesterday.
I wonder if you could answer my question "Is this exception handler invoked
before or after the ErrorPages ?"

RE: ConcurrentModificationException
Thanks, Martin!
In the init(), I have:
{
getMarkupSettings().setStripWicketTags(true);
IApplicationSettings settings = getApplicationSettings();
settings.setAccessDeniedPage(AccessErr.class);
settings.setPageExpiredErrorPage(SessionErr.class);
settings.setInternalErrorPage(InternalErr.class);
// #2 starts
getRequestCycleListeners().add(new AbstractRequestCycleListener() {
public IRequestHandler onException(RequestCycle cycle, Exception e)
{
return new RedirectRequestHandler (ERROR_PAGE_URL);
}
});
// #2 ends
}
Could the #2 code block be the cause? Is this exception handler invoked before
or after the ErrorPages ?
Our authentication strategy is set up at Apache level.
This is what SessionErr class does:
getRequestCycle().replaceAllRequestHandlers (new SessionErrHandler());
And SessionErrHandler redirect to the Login Servlet. And the Login Servlet will
be routed to the WebLogin server.

Hi,
I don't see how this may happen.
The execution of RequestCycle is single threaded.
Do you have RequestCycleListener or something similar where you start another
thread and you use the same instance of RequestCycle ?

Yes. You make a request to a page, Wicket searches for this page in the stores,
doesn't find it and throws PageExpiredException.
But, if the request url has the mount path then Wicket will create a new Page
instance instead. If you have authentication strategy set up then you go to the
Login page, otherwise this page will be rendered.
If you are able to reproduce the problem in a quickstart attach it to Jira so
we can debug it.

Ma
AjaxPagingNavigation not updating DataView
I have created AjaxPagingNavigation which is supposed to update a DataView The problem is that when clicking on a page number link to go to another page, the data view does not get updated. When the page is loaded for the first time there are no problems.. but when clicking on the page number link, the onBeforeRender() of the dataview is never called again, so it doesn't even call the populate method of the dataview or the iterator method of the data provider. but I have noticed that AjaxPagingNavigationLink.onClick(AjaxRequestTarget target) is being called. Any ideas? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/AjaxPagingNavigation-not-updating-DataView-tp4166358p4166358.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Event or Notice when a ListView's Model changes
But when the event is processed, I'm not in an AjaxRequest.
Anyway, I have something working, now, I am able to update a version field
(by sending an inter-component event in the onBeforeRender() of the
ListView that has it's own Form; the Event is processed by another Form at
the top of the same Panel - that's where the version field is), but I still
need an AbstractAjaxTimerBehavior - now at 3 seconds - to make the updates
visible for the user. That worries me, I would like to have an update
interval of a second, or even less, but I wonder if this is wise. My
solution now on the receiving side looks something like:
add(new AbstractAjaxTimerBehavior(Duration.seconds(3)) { // add to the Fom
@Override
public void onEvent(Component component, IEvent event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
==> Update VersionField
super.onEvent(component, event);
}
}
@Override
protected void onTimer(AjaxRequestTarget target) {
// This can take up to 3 seconds!
target.add(VersionField);
}
});
Of course, I would like something like:
@Override
public void onEvent(Component component, IEvent event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
==> Update VersionField
target.add(VersionField);
super.onEvent(component, event);
}
}
But I don't have a AjaxRequestTarget there, and obtaining one by
AjaxRequestTarget.get() causes an IllegalStateException (As far as I can
remember).

Re: problems with AjaxFallbackLink on IE
In fallback mode the entire page is being rendered, so there's no need to identify particular components that changed. Why it's falling back is perhaps an IE issue, but I think you should be prepared for null as Nicklas suggests.

Re: problems with AjaxFallbackLink on IE
I believe target is null when you're in "fallback" mode with an AjaxFallbackLink. You'll need to check for null and handle things accordingly, as though it were a normal link.

I'm not at office now but most surely this line is Registration.java:787 : target.addComponent(captchaImage); and I think target is null.

problems with AjaxFallbackLink on IE
Hi,
I have a problem wih AjaxFallbackLink on IE. I have a captcha image and I
want when I click on image to chage the image.
Everything worked fine, but I noted on another machine that on my production
server on IE when I click on image I got a null pointer exception. The
problem is that on my development machine I don't get the exception and i
cannot reproduce this bug. This doesn't happen on FF or Chrome, nor on IE
on my computer.
Does anyone know wich can be the cause. Here is the code:
@Override
public void onClick(AjaxRequestTarget target)
{
captchaImageResource = new CaptchaImageResource();
captchaImage.setImageResource(captchaImageResource);
equalInputValidator.setFieldValue(captchaImageResource.getChallengeId());
target.addComponent(captchaImage);
}
and a part of stacktrace :
org.apache.wicket.WicketRuntimeException: Method onLinkClicked of interface

Re: Updating Child Component Markup from Ajax
Ok, that's what I thought. My problem is that my child components AREN'T being updated. I've verified that the parent component (a group box) has a markup ID, and I'm adding the parent component to the AjaxRequestTarget. I set break points in the model class for the child value getter methods & verified they're being called. Any suggestions on where to look to figure out why the child components aren't re-rendered after the Ajax call is finished?
