Implementing AjaxBehavior with decoration
What is the easiest way to get following behavior: 1. When I click a link, a hidden DIV pops-up. The content of the DIV is loaded via AJAX. 2. While the content is being loaded (it takes a couple of seconds), I need to show the empty DIV with busy-spinner inside it. 3. The busy spinner eventually gets replaced by the content. 4. On clicking, anywhere other that the DIV, the div gets closed. I have JS to do that. I think I will have to extend AbstractDefaultAjaxBehavior and override getAjaxCallDecorator, renderHead and getSuccessScript, may be. But I am not able to be sure what goes where. Also, If I use simple Link or AjaxLink with AbstractDefaultAjaxBehavior. I am reading through these posts and a bit confused on the implementation part 1. http://blog.jayway.com/2008/09/26/wicket-javascript-internals-dissected/ 2. https://cwiki.apache.org/WICKET/calling-wicket-from-javascript.html 3. http://javathoughts.capesugarbird.com/2008/01/wicket-13-ajax-button-with-confirmation.html I am using Wicket 1.4.9.

Making Ajax Download Work With Validator Messages (in FeedbackPanel)
Guys, I almost got the Ajax Download-with-Form Refresh to work. I followed this example of how to do an Ajax download: https://cwiki.apache.org/WICKET/ajax-update-and-file-download-in-one-blow.html But there is one problem; the form has a FeedbackPanel which shows Validator messages. With this approach, no Validator errors get displayed if there is any error. The errors are in fact thrown (I verify it in the console), but they are not *shown*. It looks like I never enter the Ajax Download's getResourceStream() and I never enter Form onSubmit() if there are any errors, so I can't control the FeedbackPanel from these locations. The flow stops somewhere earlier. How do I show Validator messages in the FeedbackPanel with this approach? Thanks. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Making-Ajax-Download-Work-With-Validator-Messages-in-FeedbackPanel-tp3315334p3315334.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: Making Ajax Download Work With Validator Messages (in FeedbackPanel)
My code is below.
1) In Form Constructor:
public MyForm(String id) {
super(id);
// add BeginDate/EndDate text fields: these require validation
add(new TextField(bdate, new PropertyModel(myBean, bdate))
.add(new ErrorDateValidator1())
.add(new ErrorDateValidator2()));
add(new TextField(edate, new PropertyModel(myBean, edate))
.add(new ErrorDateValidator1())
.add(new ErrorDateValidator2()));
// add Feedback Panel
FeedbackPanel feedbackPanel = new FeedbackPanel(feedback);
feedbackPanel.setOutputMarkupId(true);
add(feedbackPanel);
// add AJAX Download object - from example
final AJAXDownload download = new AJAXDownload() {
@Override
protected IResourceStream getResourceStream() {
File f = generateFile();
return new FileResourceStream(f);
}
@Override
protected String getFileName() {
return report.xls;
}
};
add(download); // add to the form
// add Submit AjaxButton
add(new AjaxButton(submitButton) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form? form) {
// Refresh Feedback Panel
target.addComponent(form.get(feedback));
// finally initiate the download
download.initiate(target);
}
});
}
2) Form onSubmit() is blank. It never even gets this far if there is a
Validator error, and it doesn't get to the Ajax getResourceStream() either
in this case. If there are no validation errors, the download works OK. But
if there are validation messages upon submission, they must be displayed in
the Feedback Panel.

Re: Making Ajax Download Work With Validator Messages (in FeedbackPanel)
whatever you are using to submit the form with ajax has an
onError(target) method that you can override and update the feedback
panel with.

Re: Making Ajax Download Work With Validator Messages (in FeedbackPanel)
I just have one more question. I need to put a red frame around the fields that have errors, in addition to displaying the Feedback message. I overrode onError() and did target.addComponent(feedbackPanel) so I'm getting the message displayed, that part works great. Now I just need to update the red marker around the fields with errors. How do I do that?

Re: Making Ajax Download Work With Validator Messages (in FeedbackPanel)
Any help with the above question? (update red/normal border around problem fields, I need to do it manually here, I think) I was thinking of iterating over all my components and doing a target.addComponent() on each one. That updates their border, but I can't make all my components setOutputMarkupId(true), which is necessary for this Ajax update. Any thoughts on how to update the border around the problem fields with this manual invocation? Thanks a lot for your help. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Making-Ajax-Download-Work-With-Validator-Messages-in-FeedbackPanel-tp3315334p3315519.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: wicket tree
ok well I was in fact able to override the width by placing this style on the
page:
style type=text/css
div.wicket-tree {
width: 60em !important;
}

How to do document.write(Hello Word); in Wicket?
How can I write something into the HTML page, from Java code.
A similar fast metod like in javascript to write in HTML:
document.write(Hello word);
It is userfull for conditional messagge like:
If (sum==5) { document.write(It is right!) }
or it may be userfull for an simple email antispam system, like in javascript:
document.write(irresi+stiblecam+@+gma+il.com);
Thank you.

Re: Just 100K per session? That would be my dream come true! (Anyone here who has tuned session size before?)
Reading in the other thread that a session size of 100K or less is achievable, I'll admit defeat now: I have not been able to shrink some of my pages(!) to less than 200K, not to mention the sessions. Despite LDMs, CompoundPropertyModels, and no, there are no domain objects in there, and no finals. How are you measuring this? Keep in mind that if you calculate when a request is still processing, you might still be measuring temporary data (e.g. for LoadableDetachableModel, you would also measure the transientModelObject, and same for any proxies (Spring/ Guice) you might use.

If this were a sum of something else dynamic on the page, it should be done
in a model because other things can change the value while on that page.
Doing it, for instance, an AbstractReadOnlyModel would ensure that the
calculation is always current.
or it may be userfull for an simple email antispam system, like in

This makes absolutely no sense. If you had document.write on the server
side, your example would be writing the email address out in its complete
form to be rendered on the client.

Get the http servlet request from the request, and get the referrer header.
