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

thanks martin that's really informative. I thought that this funny thing is tomcat related, but wasn't sure...

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.

Problems displaying a PDF from stream
While trying to display a PDF document from stream following problems
arrise:
IE7:
Resource can not be displaied at all.
Firefox 3.6.12:
PDF is displaied but if Chronk is cleared in Firefox while document is open
then it cannot be displaied again. It is possible only after restarting
Firefox.
No errors in log.
The code:
public class PdfGen extends WebResource {
public PdfGen() {
setCacheable(false);
}
@Override
public IResourceStream getResourceStream() {
IResourceStream resourceStream = new AbstractResourceStreamWriter()
{
private static final long serialVersionUID =
1934248394380163944L;
public void write(OutputStream output) {
testItextDirect(output);
}
public String getContentType() {
return "application/pdf";
}
};
return resourceStream;
}
private void testItextDirect(OutputStream output){
try {
Document document = new Document();
PdfWriter.getInstance(document, output);
document.open();
document.add(new Paragraph("Hello World"));
document.add(new Paragraph(new Date().toString()));
document.close();
} catch (DocumentException de) {
try {
throw new IOException(de.getMessage());
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
in the init() of AuthenticatedWebApplication SharedResource added like this:
getSharedResources().add("pdfGen", new PdfGen());
Any help would be highly appreciated

Try this:
public class MyResourceStreamWriter extends
AbstractResourceStreamWriter {
private static final long serialVersionUID = 1L;
public MyResourceStreamWriter() {
}
@Override
public void write(final OutputStream output) {
// ! prduce output here and stream it to output
try {
output.flush();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public String getContentType() {
return "application/pdf";
}
}
Link pdfLink = new Link("pdf") {
private static final long serialVersionUID = 1L;
@Override
public void onClick() {
ResourceStreamRequestTarget rsrt = new
ResourceStreamRequestTarget(new MyResourceStreamWriter());
//rsrt.setFileName("file.pdf"); // use this if yout
want your browser to ask you wheter you want to save the cownloaded PDF in fil
e"file.pdf"
getRequestCycle().setRequestTarget(rsrt);
}
};
pdfLink.setPopupSettings(new PopupSettings(PopupSettings.RESIZABLE |
PopupSettings.SCROLLBARS));
add(pdfLink);

Re: Problems displaying a PDF from stream
Now it works with IE and this is most important thing. Thank you very much!
However the problem with Firefox remains. After clearing chronik while Pdf
document is open if I click the link comes "page expired", after refreshing
the main page with link if I click link again comes empty page.

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.

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

I would think that this would be more a function of the network layer on the settop box.

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 : > Hi > > Im working on a product where we are pushing a wicket "site/product" to some > set-top boxes.

Re: Wicket product on set-top boxes
hehe.. Sometimes I do spell wrong usually when tired, angels are nice but was thinking of angle or perspective :) We are actually using ajax after the initial page so i'll go for some ajax intelligence, which was my initial idea. 2010/10/28 Jeremy Thomerson > On Thu, Oct 28, 2010 at 12:40 PM, nino martinez wael < > nino.martinez.w...@gmail.com> wrote: > > > Hi > > > > Im working on a product where we are pushing a wicket "site/product" to > > some > > set-top boxes.

Re: JFreeChart with clickable imagemap
Hi, A little late maybe but since I wrote that wiki page I've improved the code to use models and so be responsive to data changes.

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? Thanks, Keep smiling yanosz - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

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 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: 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 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 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.

Of course, then it's harder to add this automatically because a border will look for the html in the parent container. - in your behavior, in the div you render, render the div with the markup ID of the component you are wrapping, and then call setOutputMarkupId(false) on the component you are wrapping. thus, you are moving the markup id up to the wrapping div. - if you are using wicket 1.4.10 or greater, implement IAjaxRegionMarkupIdProvider, which allows you to override the id of the markup region that will updated via ajax -- Jeremy Thomerson http://wickettraining.com *Need a CMS for Wicket?

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. I have made minimal changes besides upgrading to 1.4.12, and now I am seeing some of these logs appear (although I havent been able to reproduce them myself) 2010-10-27 14:36:05,070 ERROR [TP-Processor11] org.apache.wicket.request.target.resource.SharedResourceRequestTarget - unable to lazily register shared resource org.apache.wicket.ajax.wicketajaxreference/wicket-ajax.js java.lang.ClassNotFoundException: org.apache.wicket.ajax.wicketajaxreference at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1484) ~[catalina.jar:na] at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1329) ~[catalina.jar:na] at java.lang.Class.forName0(Native Method) ~[na:1.6.0_21] at java.lang.Class.forName(Class.java:247) ~[na:1.6.0_21] at org.apache.wicket.application.DefaultClassResolver.resolveClass(DefaultClassResolver.java:114) ~[wicket-1.4.12.jar:1.4.12] I also see some similar exception traces, but with different class names: java.lang.ClassNotFoundException: org.apache.wicket.extensions.ajax.markup.html.modal.modalwindow java.lang.ClassNotFoundException: org.apache.wicket.markup.html.wicketeventreference These classes are on the classpath of course, but the odd thing is the class names seem to be converted to lowercase somewhere in the app which I am guessing why the classNotFound exceptions are being thrown.

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 wrote: > On Thu, Oct 28, 2010 at 5:19 PM, Clint Checketts >wrote: > > > I have a Visitor that iterates through my forms and adds a Behavior that > > writes out to the Response a and any feedback messages that belong > to > > that component.

The markup ID of your component stays the same. In the interface, you just create an ID that will be rendered in your behavior's markup. You render that in your behavior-generated markup, and then Wicket will use the same ID for when it replaces the markup for that component - thus replacing both together. -- Jeremy Thomerson http://wickettraining.com *Need a CMS for Wicket?
