Betr.: Re: Modalwindow with confirm box on close button
Hello,
Thanks for the response!
I already use jquery in my project for other stuff, so I would be a
solution.
I hoped there was a standard fitted solution in wicket.
We override 'getEventHandler' often to override the onclick for a
behavior,
so why can't there be something like that to override the onclick of the
close button?
Does it exist or should i put it as 'new feature'?
Thanks, Marieke

Re: Modalwindow with confirm box on close button
Hi Marieke,
some times ago I've solved a similar problem using JQuery and a plugin
called jQuery AOP, but I don't know if exists a simpler solution. I used
jQuery AOP with close button which is a standard anchor with class
attribute set to 'w_close'. The following script will ask user to
confirm before closing window without sending any data to server. I hope
it could help you:
$('a.w_close').each(function(){
jQuery.aop.around( {target: this, method: 'onclick'},
function(invocation) {
if(confirm(Are you REALLY sure?)){
return invocation.proceed();
}else{
return false;
}
}
);
});
bye.
Hello,
I want to aks the user if he is sure that he wants to close the
modalwindow.
Most of the time we use the modalwindow to edit a bean. But when closing
the modalwindow with close button, we are not sure if the user wants to
save the data or not.
Using 'setCloseButtonCallback' is not an option, because showing the
confirm-box should be just before going to server (or not if user
doesn't
confirm).
Thanks for any help !
Kind Regards, Marieke Vandamme

RestartResponseAtInterceptPageException / redirectToInterceptPage with PageParameters
Hi all,
I am currently using wicket-auth-roles for all pages required authorization
which is working great.
I have a page where information is shown to the user but to see further
information they are required to login. This page uses
IndexedParamUrlCodingStrategy for the URL.
I haven't to found any way to use wicket-auth-roles to do this so I have
done the following:
add(new Link(login) {
@Override
public void onClick() {
throw new
RestartResponseAtInterceptPageException(new Login());
}
@Override
public boolean isVisible() {
return
!WiaSession.get().isSignedIn();
}
});
In the onSubmit code in the Login page I am using the
if (!continueToOriginalDestination()) {
setResponsePage(getApplication().getHomePage());
}
When clicking the login link it goes to the login page and then back to the
info page but without the PageParameters. Therefore the url is incorrect- it
has ?wicket:interface=:1:1::: and then some of my data is missing because it
requires the PageParameters.
How can pass the PageParameters through?
Many thanks
Vishal

Re: Problem with setResponsePage from a thread
From the thread you can't request anything to the application server, since
the original request that initiates the threads is already gone, what you
can do is actually create an abstract behavior with a timer that checks the
server (lets say every 5 seconds) for an status and force a redirection
from there (javascript tricks). Obviously your thread need to update this
status somewhere.

Hello everybody,
I have a form, then when all the fields are filled and I clicked the accept

executes onSubmit(). In this event I create a thread to execute other

What I want is when the thread finishes, redirect to another WebPage. But
it seems that I can not interact with redirections from the thread.
If somebody has any suggestion it would be great!
The most important part of the code is:
.
button.add(new AjaxEventBehavior(onclick){
@Override

iframe.setVisible(true);
target.addComponent(iframe);
onSubmit();

AW: Problems displaying a PDF from stream
What do you mean with After clearing chronik? Does this mean that the session
cookie is lost after After clearing chronik?
You may take a look at the generated HTML:
Onclick=.?wicket:interface=:5:.:pdfIcon:pdf::ILinkListener::
This refers to a version oft he page that is no longer valid after the session
is lost. Refreshing the page starts a new session and it works again.
You must (I don't know how at the moment) produce a sort of bookemarkable url
for this case I think. My guess would be to use a separate servlet for this.

Do you want to open the PDF in a separate window? Klick on some
button and open a new browser window with pdf?

Wicket product on set-top boxes
Hi Im working on a product where we are pushing a wicket site/product to some set-top boxes. And I want to make the displayed page more resilient, so if the server for some reason are down or the box are unable to connect it will keep trying to connect until successful. Also if I hit the exception page for some reason I want to go back to the originating page after a while to try again. So any suggestions? I have a couple of ideas, but wanted to hear other angels on it.. regards Nino

Re: Wicket product on set-top boxes
Hi! Yes, we did this kind of settop with wicket. We use ajax timer to update page and keep session alive. The originating page problem we had to resolve using a cookie because wicket does not support multi homing. ** Martin 2010/10/28 nino martinez wael nino.martinez.w...@gmail.com: Hi Im working on a product where we are pushing a wicket site/product to some set-top boxes.

Wicket scalability
Hello, I'm still trying to get into wicket - this time, I stumbled up on: http://javathoughts.capesugarbird.com/2008/01/year-of-wicket.html It says: The application was a management console for an enterprise application. It did not require high user traffic, so were weren't concerned about what people talk about as the biggest issue with Wicket, namely scalability. We certainly have had no performance problems ourselves. Although this article was written some months ago, I didn't notice any concerns refering to scalability.

Do you know, what the author is referring to? That should be worded as expected, we did not encounter what people often cite as a common misconception about Wicket, namely, that it does not scale well. People commonly spread FUD about whatever framework doesn't seem to fit their needs. The common thing to say about Wicket is that it doesn't scale well. They say that holding state in the session kills scalability. However, to clarify the simplest: that's wrong, and has been disproven by numerous examples and benchmarks. Can you write a Wicket application that won't scale? Certainly! But give me any framework and I'll write you an application that will crash. The real question is: can you write a Wicket application that scales well? The answer is: ABSOLUTELY!

Disable button double-click without breaking Form.setDefaultButton
Hello,
I have had problems with users double-clicking the Finish button in one of our
wizards, which caused duplicate objects to be created.
So I want to prevent the (non-ajax) buttons from being clicked more than once.
I found what I thought was a good solution, using a SimpleAttributeModifier to
add this to all the regular buttons
input ... onclick=this.onclick=function(){return false;};/
This worked fine, until someone discovered pressing Enter in a textfield in a
wizard stopped working, not only did it not submit the form, but it prevented
clicking the button manually. Wizard makes uses of Form.setDefaultButton, which
adds a hidden button at the start of the form, with an onclick handler that
looks like this:
input ... onclick=var b=document.getElementById('next2d'); if
(b!=nullb.onclick!=nulltypeof(b.onclick) != 'undefined') { var r =
b.onclick.bind(b)(); if (r != false) b.click(); } else { b.click(); }; return
false; /
This meant that the onclick() method of my button was invoked (disabling the
button), and then the button was clicked (doing nothing).
Has anyone found a way of disabling double-click on regular buttons without
tripping over this?
Thank you,
Alex

Replacing markup generated by a Behavior
I have a Visitor that iterates through my forms and adds a Behavior that writes out to the Response a div and any feedback messages that belong to that component. This is really great because it gives me inline feedback panels. Here is the problem: if the component is ever updated via ajax, the component the behavior is tied to get replaced in the DOM, but the feedback messages get written out in another div again. My core need is to create some sort of auto-adding inline feedbackpanel. Any good recommendations on how to work around this? It's such a good design pratice to have error messages next to the offending input fields, I'm sure others have had to deal with this.

Seeing sporadic ClassNotFoundExceptions after upgrading from 1.4.9 or 1.4.11
I was wondering if this was a known issue, or if it is something specific to my application.

Re: Disable button double-click without breaking Form.setDefaultButton
Do it in your form itself. For instance, you can save a boolean flag that tells you that the form has already been submitted and not accept a second submit, or whatever.

Re: Replacing markup generated by a Behavior
Elegant! I'd been trying to think of ways to add my own markup ID and piggyback off any render requests that redraw the component to trigger and render the feedback, just using the component markupId will work great! Instead of setOutputMarkupId(false), I'll detect that to decide to add the ID or not and just remove the ID attribute in the onComponentTag() method. I'll code it up tomorrow. I've got a good feeling about this. Thanks for the help. Also I'll check out the IAjaxRegionMarkupIdProvider. Always good to check out the new interfaces. -Clint On Thu, Oct 28, 2010 at 5:28 PM, Jeremy Thomerson jer...@wickettraining.com wrote: On Thu, Oct 28, 2010 at 5:19 PM, Clint Checketts checke...@gmail.com wrote: I have a Visitor that iterates through my forms and adds a Behavior that writes out to the Response a div and any feedback messages that belong to that component.
