Re: button click and Form with CompoundPropertyModel lose its data
If you create a new Poll object, there is no magic that will bind that
to your form instead of the Poll object you wrapped in the
CompoundPropertyModel.
You could put the poll object as a local field member in the class, and
use PropertyModel(poll, property-expression) for the fields instead.
That way you can swap out the poll-object and still keep the form in sync.
Alternatively you can apply the new Poll object to the form by doing:
form.setModel(new CompoundPropertyModel(newPollObject)) after you create
the new one.

Hi,
I am creating a form in the next format:

super(id, new CompoundPropertyModel(poll));

}
My page has also some buttons in different forms that do all kind of things.
My problem begin when I create new Poll object (so the poll is empty) and
fill the fields of the poll, but before saving it I press on one of the
other buttons. It is rendering the page again so all the data that I enter
is lost.
Same problem occur when I edit poll and before saving it I press on one of
the other buttons. It is rendering the page again so all the data that I
change is lost.
Any idea will be appreciate.
Thanks,

your buttons in different forms will submit the form they are in, so
you lose any input form any other form. this is how html works - only
one form can be submitted.
wicket supports embedded forms, so if you embed all your other forms
into one form the input should not be lost.

Double-click to select row - inmethod grid
Hi,
I subclassed the AbstractGrid class to enable double-click to select a
row instead of single-click, since it is handy to be able to click in a
row to copy text etc, and then use double-click to select instead.
Wouldn't this be a nice addition to the AbstractGrid class? Here is my
quick/dirty implementation:
public class MyDataGrid extends DefaultDataGrid {
/* Constructors */
public MyDataGrid(String id, IModel model, ListIGridColumn columns) {
super(id, model, columns);
}
public MyDataGrid(String id, IDataSource dataSource,
ListIGridColumn columns) {
super(id, dataSource, columns);
}
/* We want double-click to trigger ajax-call, not the default
single-click */
protected boolean disableRowClickNotifications() {
return true;
}
/* Add ajax-behavior for double-click */
protected void onRowPopulated(final WebMarkupContainer rowComponent) {
super.onRowPopulated(rowComponent);
rowComponent.add(new AjaxFormSubmitBehavior(getForm(),
ondblclick) {
private static final long serialVersionUID = 1L;
protected void onSubmit(AjaxRequestTarget target) {
}
protected void onError(AjaxRequestTarget target) {
}
protected void onEvent(AjaxRequestTarget target) {
onRowDblClicked(target, rowComponent.getModel());
}
public CharSequence getCallbackUrl() {
return super.getCallbackUrl() + column='+col+';
}
protected IAjaxCallDecorator getAjaxCallDecorator() {
return new AjaxCallDecorator() {
public CharSequence decorateScript(CharSequence
script) {
return super.decorateScript(if
(InMethod.XTable.canSelectRow(event)) {
+ var col=(this.imxtClickedColumn ||
''); this.imxtClickedColumn=''; + script
+ });
}
};
}
});
}
/* Override this to implement the double-click action */
protected void onRowDblClicked(AjaxRequestTarget target, IModel
rowModel) {
}
}

Re: Apache FOP and Wicket
Sure, it is possible, but it is tedious and verbose compared to using
Freemarker or another scripting language. Using Wicket for this will
only add more code and complexity to the process, and it's not like you
need component based control of the markup you are creating, so Wicket
is simply overkill for this task. Wicket isn't a golden hammer, even
though it is great at what it does/is meant for :)
Remember, you have to create both the java-side and the html-side for
every variable you put in your markup, instead of just outputting ${var}
where you need it :)
-- Edvin
Adrian Wiesmann skrev:
Why not? I was remembering that Wicket can manage any markup, not just
HTML . .
Am I missing something ?
Not sure. If you do, so do I :)
I have written a renderer which takes an XML containing some UI
description and either generates Swing, HTML (Wicket), PDF (FOP) or CSV
from the same UI description (but from different templates).
Although you can ask Wicket to generate the PDF, there is no direct link
between FOP and Wicket. Wicket only calls my renderer and forwards the
generated file to the user via HTTP.
The problem with having Wicket generate your FOP files will be that you
will have to write all UI elements on your own because there are no
classes/objects you can use.

Re: Reporting Engine on Wicket 1.3.4
The freemarker-version is something like this:
The user has created a template using the .fo format with Freemarker, a
(too) simple example could be:
http://tornado.no/template/show?template=global.fop
(Notice the list-directive to iterate over articles in this case, since
it is a CMS).
Then, in the Wicket page I do:
byte[] b = FopUtils.createPDF(aStringWithTheMarkup);
RequestCycle.get().setRequestTarget(new ResourceStreamRequestTarget(
new ByteArrayResourceStream(b, contentType)).setFileName(page.getTitle()
+ .pdf));
(contentType is application/pdf).
The FopUtils class is like this:
public class FopUtils {
private static FopFactory fopFactory = FopFactory.newInstance();
public static byte[] createPDF(String foMarkup) throws IOException,
FOPException, TransformerException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent,
out);
// Setup JAXP using identity transformer
TransformerFactory factory = TransformerFactory.newInstance();
javax.xml.transform.Transformer transformer =
factory.newTransformer(); // identity transformer
// Setup input stream
Source src = new StreamSource(new StringInputStream(foMarkup));
// Resulting SAX events (the generated FO) must be piped through
to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
// Result processing
FormattingResults foResults = fop.getResults();
out.close();
return out.toByteArray();
}
}
.. and you get a simple PDF served in milliseconds :)

My main question was - why didnt getForm() on the button work? and second - not sure how you are saying markupProvider is the form? markup provider is the page. My page markup file has the fragments. What am I missing? Martijn answered the first one I see. Sorry for not stating it right away. I was more focused on finding a solution for you :) So to the markupProvider being your form: You wrote: // Cart Header Toolbar cartForm.add(new CartActionToolbar(cartHeaderToolbar, cartActionToolbar, ViewCartPage.this, cartForm)); And your only constructor in CartActionToolbar is: public CartActionToolbar(String id, String markupId, MarkupContainer markupProvider) I didn't count the arguments, I just saw that markupProvider was the last argument, and also that cartForm was the last argument you passed into it. (God damned wrapping in the mail client confused me, I read your mail on the ASUS EEPC - not the biggest screen in the world :) It seems you don't hit this constructor at all? :) Anyways, a cleaner way to do this is to override the onBeforeRender() method of the fragment. Then the component hierarchy is complete, so you can call getParent() or even better, getForm() directly on the component to get the form. Just remember to call super.onBeforeRender() as well :) -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks a lot, Edvin.
I will try your answers to 2. and 3..
But I think, that overwriting the populateTreeItem method wouldn't help,
because i want to modify nodes of an existing tree, for example mark them
red if I click on them.
Any suggestions?
That's why you need to add an AbstractBehaviour to each item. The
onComponentTag() method will be run before the component is rendered, so
you can check the state of your userObject and add/remove classes using
the tag.put() approach :)
Also, you might look into onNodeLinkClicked() method of the tree, if you
want to perform actions when you click on an item. The
onNodeLinkClicked() gives you access to the AjaxRequestTarget, so you
can also execute arbitrary javascript code, like this:
protected void onNodeLinkClicked(AjaxRequestTarget target, TreeNode node) {
MyObject myObject = (MyObject) ((DefaultMutableTreeNode)
node).getUserObject();
if(myObject.getMyState())
target.appendJavascript(targetTheComponentWithAJavascriptMethod( +
getId() + ););
}
Either that, or you could change the state of the userObject in the
onNodeLinkClicked method and add it to the AjaxRequestTarget. Your
AbstractBehaviour will then take care of visualizing the new state of
the object for you :)

Calls to MarkupCache#putIntoCache does not use the key provided by MarkupCacheKeyProvider
Hi,
I have a virtualhosted CMS written in Wicket 1.3 where some of the pages
are loaded from the database. This is done using a custom
ResourceStreamLocator, configured in the Application#init method. This
works good.
Different users have different templates loaded for the same Wicket
page, so I need to provide a custom cache key so that instance #2
doesn't get the template loaded for instance #1. Therefore I have

Hi Johan,
OK, so I need to override the LocationString to also include my unique

Re: Calls to MarkupCache#putIntoCache does not use the key provided by MarkupCacheKeyProvider
Hi again, Johan,
I've found something disturbing:
MarkupCache#onMarkupNotFound calls putIntoCache(cacheKey,
Markup.NO_MARKUP), but putIntoCache has arguments (final String
locationString, Markup markup). In my book that seems like the concepts
of cacheKey and locationString are mixed. Is this really correct?
protected Markup onMarkupNotFound(final String cacheKey, final
MarkupContainer container)
{
if (log.isDebugEnabled())
{
log.debug(Markup not found: + cacheKey);
}
// flag markup as non-existent
return putIntoCache(cacheKey, Markup.NO_MARKUP);
}
protected Markup putIntoCache(final String locationString, Markup
markup)
{
if (locationString != null)
{
if (markupCache.containsKey(locationString) == false)
{
markupCache.put(locationString, markup);
}
else
{
// We don't lock the cache while loading a markup. Thus
it may
// happen that the very same markup gets loaded twice
(the first
// markup being loaded, but not yet in the cache, and
another
// request requesting the very same markup). Since markup
// loading in avg takes less than 100ms, it is not really an
// issue. For consistency reasons however, we should
always use
// the markup loaded first which is why it gets returned.
markup = (Markup)markupCache.get(locationString);
}
}
return markup;
}

Johan Compagner skrev:

If that is not given by the markup stream it will fallback to the cache key
Aha. OK, that makes sense :)
The database-backed page is a basepage extended by other pages, so let's
say DbPage is loaded from a database, but MyPage which extends DbPage is
always the same (from the filesystem). DbPage will get the instanceid/
prefix for the cachekey, as it has no locationString, but MyPage will be
cached using the file-location-string. Since MyPage is supposed to show
different content depending on the markup of BasePage, I guess I can't
put that in the cache at all then?

Re: Change style of TreeNode
Kai Schubert-Altmann skrev:
Hi everybody,
I have some question regarding my existing wicket tree:
1. How can I change the style or css class of one or more TreeNodes?
If you override the populateTreeItem() method, you can add an
AbstractBehaviour to the item and override the onComponentTag method.
From there you can do tag.put(class, yourValue).
2. How can I specify custom icons for some nodes?
Override the getNodeIcon() method of the tree.
3. How can i change the name, that will be shown in the tree, without
changing the name of the userObject?
I guess the simple solution would be to provide a toString() method on
your userObject that returns the desired value :)
Alternatively you could override the renderNode method of the Tree,
which by default does:
protected String renderNode(TreeNode node)
{
return node.toString();
}
Just get your userObject from the node and return the string you want
from there :)

Re: getForm() on a component inside 2nd level Fragment returns null?
Your CartActionToolbar#markupProvider is infact your form, so you can do
((Form)markupProvider).setDefaultButton(checkoutButton), or you could
make the cartForm a private field in ViewCartPage and just access it
with cartForm.setDefaultButton(checkoutButton).
For the first approach you'll need to assign the markupProvider to a
private field in CartActionToolbar, or make markupProvider final in the
constructor.
Does that help?

When using a bookmarkable page and altering the state of the page so that the url is rewritten to ?wicket:interface=:n:myPage::ILinkListener:: etc, why is the basepath / instead of the bookmarkable page's path?

Re: Why isn't the bookmarkable url kept when appending ?wicket:interface=:n:myPage::ILinkListener:: etc?
The client can't live with the url's created by HybridUrlEncodingStrategy. They are dead set on that arguments in the url should be appended with ?, not dot. Conventionally, dots does not denote arguments, and I must agree that he has a point. I think everyone would agree that keeping the bookmarkable part of the url adds value, so I must ask - is there a technical or otherwise good reason not to include it? As long as the current behaviour is the default for bookmarkable pages, it will degrade the user experience for everyone using it, and it seems this could be easily fixed.. -- Edvin Martijn Dashorst skrev: use HybridUrlEncodingStrategy to mount the page.

but then it just copies the stream, and doesn't set any headers.
Maybe this will work?

Wicket and inline JavaScript
Hi, I have a webdesigner who keeps harassing me with the way Wicket does JavaScript, attaching behaviour to onclick events etc. instead of doing it the jquery way of picking up the components and attaching the events afterwards, thus keeping all the nasty bits away from the actual markup. Ofcourse the code looks a lot cleaner the jquery way, and he tells me that debugging and working with the code is also much easier. Personally I don't know enough about html/javascript to decide what's the better approach, but I just wanted to know if there are any plans to rework this in Wicket, or if the current approach is just as good? -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat discards content-type with StringRequestTarget
Update: overriding respond and setting the contentType directly works
great :)

Sure I could, but since the StringRequestTarget constructor takes a
content-type argument, I find it strange that this isn't sent to the
browser. Sure enough, StringRequestTarget#respond, creates as
StringBufferResourcesStream with the contentType field set correctly,
but then it just copies the stream, and doesn't set any headers.
Maybe this will work?
RequestCycle.get().setRequestTarget(new StringRequestTarget(text/html,

Re: Wicket and inline JavaScript
Hi Ned,
thanks for your reply. I agree with your point of view. Today, however,
we got bitten because the designer wanted to change all buttons by
hiding them with jquery, and adding an anchor right after it in the
dom-tree, so he could style them the way he wanted it (not possible with
buttons he tells me).
You can see his lovely button on this page:
http://sd.tornado.no/domorder/search/query/testdomain
The way he then triggered the submit buttons is with the following
Jquery code:
$('.btn.submit').click(function(){
$(this).prev().click();
});
This works most of the times, but sometimes, when the wicket ajax stuff
includes references to 'this', the approach doesn't work, and wicket
tells me that the ajax request was stopped 'because of precondition'.
That's when he started bitching about the Wicket way of inlining
JavaScript, so I thought I'd be nice to hear some opinions :))

Ned Collyer skrev:
Hi Edvin,
I am an advocate of JQuery :). I even won their icon design contest, and
I've been using it for years! I think it should be used in all projects
that require effects or cool DOM manipulation.
I love the unobtrusive way and xhtml strict!
That being said, when it comes to wicket AJAX - just use the wicket ajax and
be done with it. No point mucking with something thats already excellent.
It works and its easy. Why reimplement that bit - and potentially open up
bugs that you need to go debug.
For effects and DOM manipulation, you can use JQuery by adding header
contributors. It is cleaner.. and in many instances easier to debug. It
makes development quick and painless.
If it wasn't wicket - id suggest using JQuery for ajax.

ListView and Threading
Hi,
I've created a domain search panel for Wicket. It consists of a ListView that lists all the TLD's, and a checkbox so you can order if the
domain is available. To make it a bit fancy, I iterate over the list after construction, and set a TldChecker to work on each tld.
Basically, it performs a whois search, and sets some boolean values on the tld after it's finished.
Then I have a AbstractAjaxTimerBehavior running every 500 milliseconds that adds any tld that has finished the whois-search to the
AjaxRequestTarget. This works most of the times, but on some occations, Wicket will complain about a mismatch in the hierachy. That's
obviously not the case, so I suspect the threading causes some kind of strange situation. The pertinent code:
/* The list */
final ListTld tlds = Collections.synchronizedList(getTlds());
/* A basic executor to spin off the threads */
Executor e = new Executor() {
public void execute(Runnable command) {
new Thread(command).start();
}
};
/* Iterate over the tlds and instantiate a TldChecker */
for(Tld tld : tlds)
e.execute(new TldChecker(tld, query)); // Args could be for instance com, and
mydomain
/* The ListView - simplified */
results = new ListView(results, tlds) {
protected void populateItem(ListItem item) {
final Tld tld = (Tld) item.getModelObject();
item.setOutputMarkupId(true);
/* Link to show who owns the domain if it's taken */
item.add(new Link(taken) {
public boolean isVisible() {
return tld.getDone() !tld.getAvailable()
!tld.getIllegal();
}
public void onClick() {
setResponsePage(new WhoisPage(query));
}
}.setPopupSettings(new PopupSettings()));
/* Checkbox so it can be ordered */
item.add(new CheckBox(selected, new PropertyModel(tld,
selected)) {
public boolean isVisible() {
return (tld.getDone() tld.getAvailable());
}
});
/* Some other fields, showing spinner while !tld.getDone() etc
*/
}
}
/* The timer - it stops when all the TldChekers are finished. 'Published' means
it has been added to the request target */
add(new AbstractAjaxTimerBehavior(Duration.milliseconds(500)) {
protected void onTimer(AjaxRequestTarget target) {
int running = 0;
synchronized (tlds) {
for(int i = 0; i tlds.size(); i++) {
Tld tld = tlds.get(i);
if(!tld.getDone())
running++;
if(tld.getDone() !tld.getPublished()) {
Component theTr =
results.get(String.valueOf(i));
target.addComponent(theTr);
target.appendJavascript(fadein(' +
theTr.getMarkupId() +');); // JQuery Magick, has nothing to do with the problem, tried
to remove it
tld.setPublished(true);
}
}
}
if(running == 0)
stop();
}
});
/* The HTML for the ListView */
tr wicket:id=results
td class=domainspan wicket:id=domainDomain/span/td
td
input type=checkbox wicket:id=selected/
a class=taken wicket:id=takentaken/a
!-- Some more markup, removed for brevity, like this one:
span class=searching
wicket:id=searchingsearching/span
--
/td
/tr
Wicket will complain about the checkbox with wicket:id selected. If I remove
the isVisible() method, it never fails:
public boolean isVisible() {
return (tld.getDone() tld.getAvailable());
}
What might I be doing wrong? Any idea? :))

When you do setVisible(false) on a component, the corresponding markup will be

I know that getVisible() might be called multiple times during a page-render, so I'm beginning to think that maybe it returns false on the

Re: ListView and Threading
Yes, if you want to have an invisible component made visible again via
AJAX you have to call setOutputMarkupPlaceholderTag(true) on it, or wrap
it in a WebMarkupContainer that is always visible and refresh the
container.
The component was never fully rendered or returned via AJAX without being visible. But since tld.setPublished() was set in the current
Thread, and the other booleans were set in the thread of the TldChecker, I guess that's what causing it. It seems that it acually helped to
include getPublished() in the isVisible() like this:
public boolean isVisible() {
return tld.getPublished() tld.getDone() tld.getAvailable();
}
I guess it is not water proof like this, so I'll include the
setOutputMarkupPleaceholderTag(true) as well. Thank's a lot!

Re: PropertyModel of textfield not being updated

When I step in there with my debugger it seems that the frequency field
in eventSchedule (which is the texfield's bean), still is set to the
default value. Meaning, the textfield doesn't receive the input.
When I just add 'eventSchedule.setFrequency(10)' for instance - the 10
does show up when I pop up the modal again. So, the link between the
model and the textfield is clearly working, but the model is not being
updated when typing into the textfield.

Re: ListView and Threading
Hi Lars,
Thank you for the great explanation. I'll read up on Threading and get this one
right :))
-- Edvin
lars vonk skrev:
The iteraton is called with synchronized(tlds) { ... } around, but maybe
that's not enough? Should I wrap all calls to setXXX in TldChecker with a
synchronized, or even put synchronized directly on the getters/setters of
Tld?
It is important that the read and write operation synchronize on the same
lock. As I understand it the write of the done and available flag are in
the TldChecker class which aren't locked by the same lock (the lock on tlds)
you put around the iteration. This is because another thread is the
executing of the code of the TldChecker (that is done via the Executor, if I
understand your code correctly). So in order to make sure your write of the
done and available flag are seen by other threads you can do two things:
1. Let the different Threads synchronize on the same lock. The simplest way
is to make the setXXX and isXXX methods synchronized as you describe.
2. Declare the done and available properties as volatile.
In my recollection this is the only way that, according to the JMM,
guarantees visibility in other Threads.
Another thing is that your populateItem method contains more probable
concurrency issues:
It can happen that during the populateItem method the current Tld is under
process. That would cause some strange behavior:
For instance:
/* Link to show who owns the domain if it's taken */
item.add(new Link(taken) {
public boolean isVisible() {
return tld.getDone() !tld.getAvailable()
!tld.getIllegal();
}
If the above code executes while in another Thread the TldChecker is
currently processing the same tl, then at this point it can happen that
the tld.getDone() returns false, as the TldChecker is not done yet. But
then when adding the CheckBox like below:
/* Checkbox so it can be ordered */
item.add(new CheckBox(selected, new PropertyModel(tld, selected)) {
public boolean isVisible() {
return (tld.getDone() tld.getAvailable());
}
});
The tld.getDone() can return true as it can happen that the TldChecker just
finished up with the Tld. So there is an inconsistency between the CheckBox
and the Link. I don't know the requirements of your application so I can't
see if this is bad or not.
A way to prevent this is to make sure that populateItem has the exclusive
lock for the Tld it is currently processing, so synchronize on the tld that
is in the item.getModelObject() AND make sure the TldChecker also
synchronizes on the tld it is processing.
The thing is that with these kind of Threading issues it can go right 100
times in a row and than it goes wrong for 10 times, or it may never go
wrong. If you don't use correct locking you just don't get any guarantees
from the JVM, only headaches :-).

Re: PropertyModel of textfield not being updated
Strange, because it worked with updating the value of a radio that's
tied to a model in that same bean.
Are you sure you didn't override wantOnSelectionChangedNotifications() and that the new value you saw came from the onSelectionChanged()
method or something? Or maybe you got the value from the component's getInput() method?
I tried the AjaxFormSubmitBehavior but am getting the following AJAX
error:
Channel busy - postponing
If you look in the AJAX debug window, I think you should be able to see what other ajax-event fired and didn't return yet. Maybe that can
give you a hint.
Also, I see that you do:
fooTextField.setOutputMarkupId(true);
target.addComponent(fooTextField);
in your onClose() method. The setOutputMarkupId(true) is redundant - as it has to have been set already some other place in your code, or
there will be no way for Wicket to know what component to rerender in the markup, and you would have gotten an error. I mention it, because
I think you might have misunderstood some parts of the process.

This was the same error I was getting when using the AjaxButton's
default onSubmit() method. This is why I am using AjaxEventBehavior,
which seems to be the only one that actually triggers the event. Is
there another way to submit my form?
So, I'm a bit in a bind here - btw, this happens both in Safari and
Firefox.

But if you don't send the new values using this button then how is
wicket supposed to know there is a new value?
Try using an AjaxFormSubmitBehavior instead of AjaxEventBehavior, it
will submit the form for you.

Does that make sense? The entire form is way too long and complex to

I don't see you post anything here that would indicate that you're
updating the model with data from the view..
What about saveButton and the form, can you supply that code as well?

Michael Mehrle skrev:
Sure:
saveButton.add(ajaxSaveBehavior = new
AjaxEventBehavior(JavaScriptUtil.CLICK) {
@Override

modalWindow.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback() {
public void
onClose(AjaxRequestTarget target) {
...
fooTextField.setOutputMarkupId(true);
target.addComponent(fooTextField);
modalWindow.close(target);
}
});
When I step in there with my debugger it seems that the frequency
field
in eventSchedule (which is the texfield's bean), still is set to
the
default value. Meaning, the textfield doesn't receive the input.
When I just add 'eventSchedule.setFrequency(10)' for instance - the
10
does show up when I pop up the modal again. So, the link between
the
model and the textfield is clearly working, but the model is not
being
updated when typing into the textfield.

I got a textfield:
add(fooTextField = new TextField(foo, new

eventSchedule is a bean that has a foo field which is an integer.
For some reason it's never being updated, although the field picks
it
up
when I programmatically call eventSchedule.setFoo().
I'm using this with AJAX and have all my component ids set and the
textfield added to the target.
Any ideas?

I have now redeplyed with the following log4j ConversionPattern:
%d{ABSOLUTE} %-5p [%c{1}] [%t] %m%n
I've started saving the ip of the user that creates a new session, and
then before returning the current mailuser from the session I do:

String currentIp =
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getRemoteAddr();
if(currentIp.equals(ip))

Re: jQuery sortables
Has anyone had experience using jQuery's Sortables [1] with Wicket? These allow the user to reorder lists, even nested lists, by dropping and dragging them in the browser. The main interface back to Wicket would probably come in the serialize method, which returns a String representing the new ordering of the items in a Form-escaped format, probably best shown with an example. Try the DnDSortableHandler from wicketstuff-jquery. It gives you a nice method to override like this: public boolean onDnD(AjaxRequestTarget target, MarkupContainer srcContainer, int srcPos,MarkupContainer destContainer, int destPos); Quite easy to setup and use :) -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You should put parent around ?:. The '+' op is evaluated before !=. Your

getId()/hashCode() since I'm IN the session when I'm doing this :)

override in the Application#init method:

The point of this is to mount pages directly on /. What it does is basically pass some url's (starting with css/gfx or js to a
WebExternalResourceRequestTarget, or else sends the parameteres to a another page that will know how to get data from the database based on
the parameteres and display the correct page.
It's based on a tip from Igor a while back, so probably it's safe unless I
managed to severely fuck it up :)

Today I deployed an application based on Wicket 1.3.3 that has close to 10.000 users. After a couple of hours we started getting reports from users saying that even upon requesting the login-page, they were already logged in as an arbitrary user. The users they were logged in as had previously performed a succesful login. It seems like the wicket-sessions bleed over between different http-sessions. I tried changing from HybridUrlCodingStrategy to mounting the pages with the normal mountBookmarkablePage() method, but the results are the same. I also tried downgrading to 1.3.2 with the same results. Can anyone think of a logical mistake I might have made?

Re: Invoulentary session sharing/leakage in Wicket 1.3.x
is it really the wicket session or a page? I believe it's the session, but I'm not sure. The hijacker is able to navigate through all pages as the hijacked user.. And on the top of every page there is a logout button and text saying Logout username. I'm not running in a clustered environment, just plain Jetty 6.1.7 in setuid mode. I'm using the SecondLevelCacheSessionStore, but I'm thinking about trying with the HttpSessionStore now to see if it makes any difference.

Re: Sorting and ListView
I'm using a ListView to display contents of a List of a domain object. Pretty simply. However, the domain has a name on it that is internationalized, ie it will used a key value from a dot properties file. The issue is is that the List of object must be sorted based on the internationalized value of the name. Currently I'm using the localizer to get the internationalized values and then sorting the List but the localizer complains, something about not being attached to a page yet. Does anyone else have a better way of doing this? The problem arises because you do the sorting in the constructor of the page, where i18n-info might not be available (depending on how the page was constructed). Wrap the sorting in a LoadableDetachableModel and return the sorted list from that and pass it to the listview. This way, the list isn't constructed before it is consulted the first time, and then the page will know about i18n-settings. -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
FeedbackPanel#newMessageDisplayComponent throws NullPointerException if empty message is inserted
Hi,
I sometimes do:
try {
// work
} catch (Exception e) {
error(e.getMessage());
}
and came across an Exception that didn't have a message, and was greeted with a NullPointerException from the FeedbackPanel. Ofcourse this
was my mistake but maybe the code could be changed like this:
protected Component newMessageDisplayComponent(String id, FeedbackMessage
message) {
Label label = new Label(id, message.getMessage().toString()); // Current
Label label = new Label(id, message.getMessage() != null ?
message.getMessage().toString() : getString(emptyMessage)); // New
label.setEscapeModelStrings(FeedbackPanel.this.getEscapeModelStrings());
return label;
}
.. and then add emptyMessage or some key to FeedbackPanel.properties or is this
a bad idea?

wicket:enclosure bug: setObject(null) called for excplicitly invisible fields in a non-visible enclosure (Wicket 1.3.1)
It seems that the value for fields that are made invisible because a
surrounding enclosure is actually lost on submit of the form.
Consider the following code:
public class HomePage extends WebPage {
private MyObject myObject;
public HomePage(final PageParameters parameters) {
myObject = new MyObject();
myObject.setField1(field1Value);
myObject.setField2(field2Value);
Form f = new Form(f, new CompoundPropertyModel(myObject));
add(f);
f.add(new TextField(field1).setVisible(false));
f.add(new TextField(field2));
f.add(new Button(submit) {
@Override public void onSubmit() {
System.out.println(Field 2 value should be 'field2Value'
but is : + myObject.getField2());
}
});
}
class MyObject implements Serializable {
private String field1;
private String field2;
public String getField1() {
return field1;
}
public void setField1(String field1) {
this.field1 = field1;
}
public String getField2() {
return field2;
}
public void setField2(String field2) {
this.field2 = field2;
}
}
}
With the following markup:
form wicket:id=f
wicket:enclosure child=field1
input type=text wicket:id=field1/
input type=text wicket:id=field2/
/wicket:enclosure
input type=submit wicket:id=submit/
/form
Field1 keeps it's value onSubmit, but the value for field2 is lost, and my model object has null in field2. If I implicitly call
setVisible(false) on the TextField for field2, the value is kept onSubmit.
Can someone confirm that this is a bug? Incase I'll create a JIRA-issue for it
and attach a quickstart.

Re: wicket:enclosure bug: setObject(null) called for excplicitly invisible fields in a non-visible enclosure (Wicket 1.3.1)
so you are saying that: when the page renders none of the fields are shown. after submit, however, myobject.getfield1() is still field1value but myobject.getfield2() is null - which implies that textfield2 is still processed even though it is inside an enclosure that has been hidden? if so, then yes, please file a bug.

You could do:
add(new Label(info, new Model() {

Also, depending on your need, you could pass in the User in the page

Can you control the order of wicket:head contra added headercontributors?

If I want to add another javascript-reference that utilizes jquery in the wicket:head tag of the childpage, I run into trouble because the wicket:head tag is rendered before the headercontributors from the basepage, hence the code fails because jquery is not yet loaded (this happens for many jquery-addons if they are added before jquery.js).

Re: Can you control the order of wicket:head contra added headercontributors?
not sure we support that, or want to support it...
if you are using a headercontributor in one situation, why not use it
also in your child page?
-igor
In my childpage, the head-section actually does more than just load the other javascript-file. It also does initialization for the
jquery-components etc, like for example:
$('#lang li').hover(
function () {
$(this).find('ul').removeClass('collapsed');
},
function () {
$(this).find('ul').addClass('collapsed');
}
);
When my webdesigner needs to add stuff like that to a subpage, he can't add it to the head, because it will be rendered before jquery etc.
Then, for every page he needs to do some jquery-magick in, I need to go:
response.renderJavascriptReference(new ResourceReference(ThisSubPage.class,
extra-init-stuff-for-that-page.js));
.. in that particular page. And he needs to put the js-stuff in this separate
file instead of the head of the subpage, where it belongs.
It's OK for webdevelopers that does design/css themselves, but a real pain when
you have designers working on your project.
Can you think of a good solution for this given the current possibilities in
Wicket?

i'm sorry this one slipped through. i commited Per's fix. Edvin, can you try with latest trunk to verify it's fixed? Done. It works good :) -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: DDC and page reload
I have a little problem with drop down choices. I have one on my page. It stores some currencies. In the same page, I've got a Flash module, who needs the actual currency to work. I pass it using the usual flashvars. But when I change a currency on the DDC (ie from USD to EUR), the actual page is refreshed (or seems to), but the currency passed in the flashvars is the old one (USD) although all of my models are properly updated. So I think wicket hasn't recomputed some markup... Can I force him to fully reload (recreate) the current page when a onSelectionChange event is fired? I think it would be easier to help you if you supplied some code :) -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Fix typo on http://wicket.apache.org/community.html
Hi, I'm sorry for being a wordnazi, but could someone please change nabble to Nabble on the three entries where it is lowercase on: http://wicket.apache.org/community.html (In the mailing list section) It is correct for Wicket Users but lowercase for the rest of the lists. It's really bugging me :) hehe -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Simple edit form and models
First of all I want to congratulate Wicket guys for their work.
Until today I have developed applications based mainly on SWT/RCP and
JSP/Servlets.
Currently we are evaluating various frameworks in order to initiate a new
project, which will expose many of our in-house developed system (SWT/RCP)
functions through web.
It seems that Wicket is very close to what we are looking for, because more
or less we have the same logic in our gui applications.
I am trying to create a common template for edit forms responsible to edit
properties of a single pojo. In general, I want to have fool control over
the synchronization between the form’s data and pojo’s fields.
I am posting some simple code.
I would appreciate if anyone has the time to take a look and tell me if I am
following a right approach about the models and the binding technique.
Out of curiosity - what are you going to do that needs this fool control over the binding process? I find in most cases that using
CompoundPropertyModel for the whole form and overriding some fields with another PropertyModel for example is sufficient in almost every
usecase. I would do something like:
public class InputForm extends Form {
public InputForm(String id, IModel model) {
super(id, model);
add(new TextField(personCode));
add(new TextField(lastname));
add(new TextField(someSpecialField, new PropertyModel(someOtherObject,
fieldname));
add(new Button(save) {
@Override public void onSubmit() {
// Save
}
});
}
}
Wicket takes care of all the manual labour concerning binding you are used to
from RCP-programming, so why not just let it shine? :)
Is it too memory expensive to keep instances of pojos inside the form?
Does the session keeps information for all pages or just for the current
page?
Normally you supply the form with a IModel, and depending on the size/nature of the model object you would use a LoadableModel to avoid
saving the whole object when you move on from that page.
Wicket 1.3 now uses SecondLevelCacheSessionStore per default, and I think only the current page is in memory, and that subsequent pages are
saved off to disk, so normally you don't need to think about optimizing for memory usage unless you have a very special case on your hands.

Workaround for AjaxEditableLabel yields java.lang.IllegalAccessError (WICKET-1239)?
Hi, I really need the AjaxEditableLabel in my application, but because of https://issues.apache.org/jira/browse/WICKET-1239, it seems useless at the time. (Just tested with Linux/Java 1.6_04/Wicket 1.3.1). Does anyone know of a workaround in the meantime? java.lang.IllegalAccessError: tried to access method org.apache.wicket.Component.onModelChanging()V from class org.apache.wicket.extensions.ajax.markup.html.AjaxEditableLabel$1 -- Edvin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Wicket 1.3: I would like to translate all resource bundles to Norwegian
Hi, Would it be OK for me to translate all the .properties-files in Wicket to Norwegian and have them included with the distribution? I think that would make a lot of Norwegian Wicket-users happy :) If OK, how do I submit the files to you guys?
