Re: stream content with an IndicatingAjaxLink
Ok, thanks.
Are you streaming the photo directly to the output stream of
the request that came in from clicking the link?
Yes I am ... but it does not work.
Apparently no one is doing that, so it is not the way to do it.
I try with the normal link and and some kind of javascript then ...

Use a visitor, something like
featuresList.visitChildren(MyPanel.class, new IVisitor() {
public visit(Component component) {
doStuffWith((MyPanel) component);
return STOP_TRAVERSAL;
}
});
You have to take on account that repeaters only create their
Items in onBeforeRender, so before that point you cannot find
the children (or you might find stale children from the
previous rendering). As you set reuseItems to true, the Items
stay the same in your case I suppose.

Re: ListItem queries
1/ MyPanel needs to use it inside the anonymous class.
2/ if its final, you cant reassign it.
3/ if i remove a panel from the list (using something like MyPanel.remove())
then its not set to the correct panel.
Doesn't quite work - a bit more complicated than u'd first expect.

Do you have a > specific use-case or is that just a potential issue you can think of? I'm thinking generally of state changes that occur in separate processes, changes that need to be presented in Web views. Specifically, I have a Web page that shows recent user activity, in a list view, where each element is a user activity event. Not all of my users are Web users, so the underlying list model is receiving events from other processes (mailer daemon, and so forth).

I was forgetting that instances of these things - pages, components and models - are apt to be serialized out of memory. Non-Wicket threads can't even hold a reference to them. So there's no point in exposing the page lock for other threads (as I suggested). > If you want to do stuff in background threads then let page/request > threads poll them if they are finished. Then the underlying list model (in my example, above) does not belong in the page; instead it belongs in the Application instance. There it can safely register with other threads, and receive events from them, because the app will never be serialized out of memory. And the list view (in the page) can hook up with the model (in the app), at request time, with appropriate synchronization - polling it, as you say. My only other question, then, is the app life cycle. (This article doesn't really answer my Q: http://cwiki.apache.org/WICKET/lifecycle-of-a-wicket-application.html In a clustered environment, are there multiple instances of the app? Might the page (the one with the list view, for example) find itself connecting to a different instance of the app, a different instance of the list model, from request to request? In a non-clustered environment, can I safely assume a single instance of the app, at any given time? -- Michael Allan Toronto, 647-436-4521 http://zelea.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

ListItem queries
Hi,
I need to get access to the first panel added to a list item in
onBeforeRender from its parent.
I have the following
ListView featuresList = new ListView("listView", myList) {
protected void populateItem(ListItem item) {
MyPanel panel = new MyPanel("panel", item.getModelObject()));
item.add(panel);
}
}.setReuseItems(true);
How would I go about getting the first panel added?
Rgds

Are you streaming the photo directly to the output stream of
the request that came in from clicking the link?
Take on account that in Ajax, the browser does not make a
normal HTTP request, but an XmlHttpRequest from Javascript,
and then expects an XML fragment as a response (a piece of
DOM tree as far as I know). I cannot imagine how could you
transmit an image via Ajax, but if it is possible, please
let me know :)
In AJAX debug console (shown on the page when running Wicket
in development mode), you can see the requests going in, the
responses coming back, and whether there were errors.
I think that you would be best off by ripping the javascript
of showing the indicator wheel and attaching it to a normal
link instead of an Ajax link.
Best wishes,
Timo

I think that by default, Java assumes the character encoding it gets from the operating system, but you can override it by explicitly setting the relevant system property, -Dfile.encoding=utf-8 or something like that. The root problem is that property files are plain text files that do not contain any metadata such as what encoding they are written in, so anybody reading them just needs to assume something. The same goes for Java source files. The problem of property files is partially solved by using property XML files, though it is a pity to lose the nice, simple property file syntax with the change. > Have you guys any idea on how to fix it?

RE: Problem with Wicket and MySQL
Okay, I'm not sure how you've set up the project, but I remember that
you sometimes had to copy the JDBC driver into the tomcat lib directory.
Haven't touched tomcat in a while, but there are project specific libs
and container specific ones - if you put it in the container lib dir
you'll avoid these classloader issues.

RE: Problem with Wicket and MySQL
You need to download the MYSQL JDBC driver and put it in your classpath.
That'll fix it.
The code is trying to load the JDBC driver 'by name' - since it's not
there it can't find it.

Strange problem cancelling out of a modal
I've got a strange problem cancelling out of a modal. Unless I make selections on all my form components inside that modal, it just won't close. Debugger shows that the cancel button's onSubmit() method doesn't even get called, unless I fill out all the fields and select all the radios. The AJAX panel doesn't show any errors either, neither does the feedback panel. I suspect this has to do with those components being set to required, but I never had a problem like that before. Any idea what's going on here? Michael
Re: AjaxButton without a Form
That is an option, but would rather use;
I have styles around my input buttons that I want to reuse. I'm sure I can
create my own custom component, but thought someone has probably done it or
has a good way around it.

Set request in WicketTester
I'm using Wicket 1.2.
I'm using WicketTester, but my Page requires certain request headers. What
is the appropriate way to add headers to the MockHttpServletRequest (via
addHeaders(...) I assume) before the Page is rendered?
I tried:
tester.getServletRequest().addHeader("host", "www.myhost.com");
tester.startPage(MyPage.class);
tester.assertRenderedPage(MyPage.class);
but that doesn't work; request.getHeader("host") returns null in
MyPage.onAfterRender().
Thanks,
Nate
Re: [inmethod-grid] javascript error closing modal window containing grid
Nope, that didn't help. I did identify another use case. When the grid is hidden via javascript, the error is thrown as well. I have attached another quickstart with this additional scenario. I believe that the modal window is probably doing something similar when closing thus triggering this error when making the grid hidden. Therefore, this issue may have nothing to do with modal dialogs, but with hiding the grid control via js. http://www.nabble.com/file/p17324786/modal-grid.zip modal-grid.zip Chuck Matej Knopp-2 wrote: > > Hi, > > I'll look at it as soon as I get some spare time.

Re: [JUG] Advanced Wicket - Cincinnati, OH (tonight)
Well, I don't really have slides. I'm doing more of a code "walkthrough". Here's the example code, though: http://svn.carmanconsulting.com/public/wicket-advanced/trunk I'm basically stepping through user stories, creating a site for managing a martial arts school. I need to get those IDEA files out of there! :) It's kind of late to think of doing a video. I'll ask the place that's hosting if they have video equipment. They do video conferencing all the time.

RE: Wicket java.lang.IllegalAccessError bug?
I can't get the ternary statement you provided to compile correctly
using 1.4-M1. The error I get is:
The type AbstractChoice is not visible
Due to the fact that the common ancestor for ListMultipleChoice and
ListChoice is the inaccessible package protected object AbstractChoice.
This is caused by the behavior of ternary assignment where, if the
second and third operands are of different reference types, then it must
be possible to convert one of the types to the other type (call this
latter type T) by assignment conversion; the type of the conditional
expression is T. It is a compile-time error if neither type is
assignment compatible with the other type. This is copied verbatim from
http://java.sun.com/docs/books/jls/second_edition/html/expressions.doc.h
tml#290293
Casting one of the new statements to FormComponent allows the statement
to compile and run without error for me:
FormComponent o = false
? (FormComponent) new ListMultipleChoice("",
new Model(), Collections.EMPTY_LIST, (IChoiceRenderer) null)
: new ListChoice("",
new Model(), Collections.EMPTY_LIST, (IChoiceRenderer)
null).setNullValid(true);

Yap. If you rephrase it into ifs (or change ternary false state into
true) it works fine.

Re: .properties files question
My question isn't about i18n. Wicket has its own very nice system of properties (MyApplication.properties, MyWebPage.properties) which makes it so easy to get when one writes his HTML files. Can we ask wicket to get the value from a key in a java class just as easily? I don't want to specify the path or even the name of the property file, I shouldn't have to: no need to do it in the HTML files, why would I have to in my Java classes? -- View this message in context: http://www.nabble.com/.properties-files-question-tp13821533p17316712.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
stream content with an IndicatingAjaxLink
I have a download picture link which take a bit of time. Result is that the
user is impatiently clicking several time. I would like to have a kind of
timer showing process and I tried to use IndicatingAjaxLink which does the
job. But I cant find out to stream to the outputstream with an ajax link.
I tried both to get outputStream from ajax target.
public void onClick(AjaxRequestTarget target) {
target.getHeaderResponse().getResponse().getOutputStream();
...
or from a new target on requestCycle from page
public void onClick(AjaxRequestTarget target) {
public void onClick(AjaxRequestTarget target) {
target.getHeaderResponse().getResponse().getOutputStream();
target.getPage().getRequestCycle().setRequestTarget(new
IRequestTarget(){
public void respond(RequestCycle requestCycle) {
((WebResponse)requestCycle.getResponse()).getOutputStream();
...
None works ... Any advice ? Something with resources maybe ?
Here is the onClick method with a normal link.That works fine.
public void onClick()
{
final byte[] bytes = getDirectDownloadBytes(phot);
if(bytes != null && bytes.length > 0) {
getRequestCycle().setRequestTarget(new IRequestTarget()
{
public void respond(RequestCycle requestCycle) {
WebResponse r =
(WebResponse)requestCycle.getResponse();
r.setAttachmentHeader(fileName);
try {
r.getOutputStream().write(bytes);
} catch (IOException e) {
throw new RuntimeException(e);
} finally { }
}
});
}
}

Automatic sign-on using HTTP headers
Hello - I am in the process of porting a Struts application into Wicket, and would appreciate some insights regarding an upcoming task: I need to implement automatic sign-on based on the value of a custom HTTP header in the request, if the request is coming from a specific IP range. For those familiar with Struts - previously this has been handled using custom RequestProcessors, where you have access to the HttpServletRequest object. I have taken a look at the Wicket API, and ended up obeying the advice to mail this list before depending on WebRequest's getHttpServletRequest() method directly. So, my main questions: - Does Wicket provide access to custom HTTP headers in a request via other means than getHttpServletRequest()? - Where in the Wicket land would YOU place the code responsible for automatic sign-on (every request that needs sign-on should go through that code before sending to a login page)? Thank you in advance for any comments on this. Best regards, Lauri Lehtinen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: IndexOutOfBoundException and PropertyModel

The person.name check getPerson().setName() , getName(). If the person is null you will get a nullpointer.

Encoding problem when deploying on production server
Hello guys,
I have a problem with the encoding of some text, on my deployment server
(Unix/Linux). I use wicket to generate the body of emails, with this code:
StringResponse stringResponse = new StringResponse();
Response originalResponse = RequestCycle.get().getResponse();
try {
RequestCycle.get().setResponse(stringResponse);
render();
} finally {
RequestCycle.get().setResponse(originalResponse);
}
return stringResponse.toString();
All of my resources files are encoded with UTF8.
When I use it on my development workstation, everything works fine.
Every chars are properly rendered.
But on the production server, it seems that the email is converted to
ISO8859-1 (and special chars are not rendered properly in UTF8). But
others web pages are properly rendered (I only have a problem when
dealing with responses)
Have you guys any idea on how to fix it? Do I have to do someting on the
server config?
Thank you vm!

Form validation when using custom onSubmit()
Hi, I have a page with several validation constraints : Required,
NumberValidator.minimum(...), ... and a FeedBackPanel to display
corresponding error messages.
When not overriding the default submission method, the validation works
perfectly and the error messages are displayed upon submission on the
FeedBackPanel.
The issue is that I have to call a custom business code when the form is
submitted, and then redirect to another page. So I overrid the onSubmit()
method like this :
Button uploadButton = new Button("uploadButton") {
private static final long serialVersionUID = 1L;
@Override
public void onSubmit() {
// The business code call
setResponsePage(ThePageAfterSubmission.class);
}
}.setDefaultFormProcessing(false);
The problem is that now the form doesn't go through validation anymore.
What's the solution?
