This might not be the rigth forum to ask CSS questions and is sort of
offtopic. But usually when something works in IE and doesnt in firefox
it means that IE breaks standard compability, and due to some bug in
IE
works anyway. My prefered way of working are using firefox to develop,
checking in IE and then fix so it works in IE too..
Could you show the corresponding html?

Hi,
I have made a stylesheet to change the default look of the

css
is
in the same package. The css looks like this:
li.feedbackPanelERROR {
background-image: none;
color: red;
padding-left: 0px;
background-repeat: no-repeat;
background-position: 0px;
list-style-type: none;

background-image: none;

background-repeat: no-repeat;

This works fine in IE7, but for some reason only works partly in
Firefox.
The green background-image is removed but the text is not red, and
is
indented as in the original. Looking at the styles with Firefoxs
WebDeveloper shows the correct styles. Anybody experienced this and
found a
solution ?.

IE 6 7 Ajax Refresh Issue
Hello, I have on a page 3 radio buttons in a group and for each radio a drop down: xDropDown1 V oDropDown2 V oDropDown3 V When the user selects a radio, the corresponding dropdown will be enabled and the other two disabled. In Firefox, this works as I need it to, but in IE, the dropdowns are not enabled/disabled as needed (either not at all - in IE6 or oddly in IE7). The funny thing is the functionality is there - i mean, although graphically they are wrong, I can change the values only for the dropdown which is enabled. And when I try to do that, all the dropdowns will be updated correctly. Any ideas what's wrong with IE and how i could update the dropdowns correctly? I use just setEnabled(true/false) and target.addComponent(...). Thanks, Cristi Manole

Re: Throw AbortWithWebErrorCodeException in onBeforeRender
While creating a quickstart for the jira issue, I noticed that it only occurs when using custom error pages as described on http://cwiki.apache.org/WICKET/error-pages-and-feedback-messages.html ... so maybe jetty creates a new (internal) web request and the application gets detached before the old request can be cleaned up properly. as far as i could see the getApplication method is only needed for checking if the app is in development mode and does some additional cleanup if it is ... anyway, the issue can be found on https://issues.apache.org/jira/browse/WICKET-1478 regards, Michael igor.vaynberg wrote: jira... -igor On Wed, Apr 2, 2008 at 2:41 AM, Michael Sparer [EMAIL PROTECTED] wrote: (Using wicket 1.3.2) I have a super class (WebPage) that throws a AbortWithWebErrorCodeException(404) depending on some properties of its subclasses.

Re: Throw AbortWithWebErrorCodeException in onBeforeRender
Maybe I didn't explain it precise enough, the subclass ain't the right place
to do that cause my usecase is like:
class Super {
onBeforeRender() {
if (!isValid()) {
throw Abort...Exception(404);
}
}
abstract boolean isValid();
}
class Sub extends Super{
boolean isValid() {
return false;
}
}
to see it in action take a look at the quickstart attached to the jira
issue :)
https://issues.apache.org/jira/browse/WICKET-1478

a certain class right? So I think the subclass itself is the correct
place.

(Using wicket 1.3.2) I have a super class (WebPage) that throws a
AbortWithWebErrorCodeException(404) depending on some properties of its
subclasses. Therefore I can't check the subclasses' properties in the
super
class' constructor and throw the exception there.
So I tried to throw it in the onBeforeRender method instead. The Error
page
for the 404 gets rendered and displayed without problems however an
exception gets thrown (see below).
So my question: where's the (right) place to throw the exception? I also
tried RequestCycle.get().setRequestTarget(new
WebErrorCodeResponseTarget(404)); with the same result.
thanks in advance

Get back value for a RatingPanel
Hi
I have a problem to get back the value of a rating panel. It displays well.
This is the déclaration :
RatingPanel rating = new
RatingPanel(str_rating,model_rating,5,true){
private double rating = 0;
protected String getActiveStarUrl(int iteration){
return WICKETSTAR1;
}
protected String getInactiveStarUrl(int iteration){
return WICKETSTAR0;
}
protected boolean onIsStarActive(int star)
{
return star ((int)(rating + 0.5));
}
protected void onRated(int rating, AjaxRequestTarget target)
{
this.rating = rating;
}
};
rating.setRatingLabelVisible(false);
this.form_evaluation.add(rating);
And in the method on submit of my form :
protected void onSubmit() {
log.info(+model_rating.getObject());
setResponsePage(new
ProjetPage(ajoutinftechnique));
}
But the value is null, so how i can get back the value of this special panel
?
Thank you in advance for your help.

Re: Get back value for a RatingPanel
Where do you set the value of the model?
It looks to me like you need to get rid of rating double in the panel
and use that as the model value.
Something like this:
protected boolean onIsStarActive(int star)
{
return star ((int)(model_rating.getObject()+ 0.5));
}
protected void onRated(int rating, AjaxRequestTarget target)
{
model_rating.setObject(rating)
}
Note i skipped all casts / type checks etc.

Re: Writing to .properties files and make changes happen?
Damn... Yes, it was the false path... Obviously the .properties file must be
changed in the context of classes, not in the source...
Thank you very much!!!

Re: wicket, spring and aop
Hello,
im quite new to spring, but afaik you cant have spring manipulating
wicket itself; however you could create a spring based proxy-class for
those purposes and have it used by @SpringBean(name=name) where you
put the logic in it;
maybe its possible to have a wicket-PageClass be also a managed by
spring but im not sure if this works...
Is spring spewing out its lines at your current app startup? (if not:
http://cwiki.apache.org/WICKET/spring.html helds details for this)

Hi there,
I'm just trying to integrate wicket 1.3.2, spring 2.0 and aspect oriented
programming (spring-aop). I've an aspect for instrumenting a dao provider that
is defined as follow:
@Aspect()
public class DaoProviderInstrumentation {
@Around(execution(* *(..)) target(org.mypackage.dao.DaoProvider))
public Object executeFinder(ProceedingJoinPoint pjp) throws Throwable {
// stuff not important for now
}
A dao provider is intended to be an interface similar to the following:
public interface Daos extends DaoProvider{
public AnimalDAO getAnimalDao();
}
where AnimalDAO is another interface with methods to retrieve animals. The
instrumentation should get executed when i'm trying to access to the getAnimalDao() and
it should create a proxy of animalDAO that exposes finder methods to retrieve
animals using some conventions defined by name of the methods.
The instrumentation isn't executed. I know wicket is not managed but i like the
wicket framework and it would be great to use integrate it but i don't know if
it is possible and what is the correct way of doing it.
I've tried to use the SpringWebApplication in the wicket-spring package but i
don't know how to use it to integrate the instrumentation.
I don't need to inject components using the @SpringBean annotation.
Thanks for your time,

Re: Removing the jsessionid for SEO
Hi Jeremy,
Hi Dan,
for a project long ago I had the trail of making a product-browser SEO
friendly; I used a plain PagingNavigator at first, and then extended it
to have it to use the IndexedUrlPageParameters; this allowed me to put
anything into the path to have a nice URL;
the key here is to look at the URL and treat it as a unique resource
line; so I did it sth like that:
mountName{(/anyparams)}*{/pageNumber}
this gave me the possiblity to have a browsing URL where I could put
anything in while the rest still works; remember also that the URL for
SEO may (!) change in future, so go for maximum flexible designs, up you
see a resource, then any params to feed the spider (there may be 0 to
over 10) and a hook at the end that has to be a number (where 0 is
pretended in case nothing at the end is a number);
so I was able to finally let the spider see things like:
e.g:
product/brand_New/BestItemOfTheWorld
product/specialCategory/moreSpecial/moreInfo/2
product/spcialCategory/moreSpecail/brandName/moreDetails/1
etc.
now, you wonder if I feed the spider with this how do I know where to
end? the key was that the part between got merged internally and was
specified by the application so we overcome the problem of:
a, recreating the view that should be the right one (here: we had a
tree-like behaviour for our products where we could compare to the tree
in database)
b, duplicate content (very bad! - never, ever have a spider find the
same content (or very very similar!) under more than one URL !)
this strategy did very well; Today with wicket 1.3 I would go nearly the
same but stick to the HybridURL scheme, and maybe try to be even more
flexible with URL scheme by having the basic schemes and resources
specified in persistence (URL-hook, initialState); Remember it is
important to feed same resources under same URLs out, else the spider
will think you might try to fake content for him;
The jsessionID is sth. I dont care about anymore - its 2008, spiders
knows it and the usual visitor/ surfer has no clue how to different a
URL from an emailadress; however many people have turned cookies + JS
off because of security fears - in turn the JSessionID will concern only
few people who know about some details but hamper many people that have
no knowledge of the internet and its techniques all over - IMHO.
@Jeremy: your aproach also seems interesting to me, can you give more
details about it?
Best,
Korbinian

Re: ModalWindow and Ajax?
:)
After instantiating your modal window. You can do something like this:
AjaxLink popupLink = new AjaxLink(manageWeightPop) {
@Override
public void onClick(AjaxRequestTarget target) {
*
target.appendJavascript(Wicket.Window.unloadConfirmation = false;);*
modalWindow.setTitle(Weight Log.);
modalWindow.setMinimalHeight(600);
modalWindow.setContent(new ManageWeightPanel(modalWindow
.getContentId(), modalWindow,
new BaseEntityDetachableModel(getPerson(;
modalWindow.show(target);
}
};
Which means that the modal window showing up will not give that
confirmation thing.

Re: IE 6 7 Ajax Refresh Issue
Hi,
I've been searching around a bit and found the solution. I figured maybe
someone else will face the same issue. It's pretty darn simple anyway.
I used to do what I wanned like this:
someRadio.add(new AjaxEventBehavior(onchange){...}
This worked great in FF, but in IE7 it didn't... all i did is change
onchange with *onclick* and now it works in both.
I think that FF handles onchange for the *newly selected item* while IE7
does it for the *element which gets deselected*. I'm not 100% sure, anyways,
maybe somebody can say for certain.

I'm using a ListView to display contents of a List of a domain object. Pretty simply.

The issue is is that the List of object must be sorted based on the internationalized value of the name.

no, you are not missing anything. you see, when you go stateless, like

makes stateful links Just Work. Without state you are back to the
servlet/mvc programming model: you have to encode the state that you
want into the link, then on the trip back decode it, recreate
something from it, and then apply that something onto the components.

Re: java.io.StreamCorruptedException: invalid type code: 29
I think I've found the solution for my StreamCorruptedException problem.
Inside the org.apache.wicket.Page, there is a constant LATEST_VERSION which
value is -1. In my application, the versionNumber passed as parameter to
the method getVersion(final int versionNumber) inside Page is never -1, the
initial versionNumber of a page is always 0. When this versionNumber is
different from 0, the versionManager object inside Page is not null, so the
flow goes to the else block inside the getVersion() method.
If LATEST_VERSION is -1, the flow of my application is always going to the
if block below, never to else block, as my versionNumber is always = 0, so
depending on the versionNumber, no page will be recovered, which was leading
to the StreamCorruptedException, maybe because wicket was trying to
de-serialize the wrong version of my page.
if (versionNumber != LATEST_VERSION) {
page = versionManager.getVersion(versionNumber);
}
else {
page = versionManager.getVersion(getCurrentVersionNumber());
}
I've changed LATEST_VERSION value to 0, and now my application works
perfectly. Are these assumptions correct? Does anytime versionNumber assumes
the -1 value?

1) The line 298 of SecondLevelCacheSessionStore =
getLastPage().getVersion(versionNumber) is returning the correct page,
because inside the getVersion() method, the versionManager object is null.
In this case, the screen that I'm testing works perfectly.
2) For the screen that throws the StackOverFlow and
StreamCorruptedException, for some reason the versionManager object is not
null, and it returns a null page object.
Another strange thing is that after the line 393 of Objects.java = return
ois.readObject(); = while debugging it using Eclipse, after this method
call the flow goes straight to the line 363 of AbstractPageStore.java,
without entering the finally block. So, an infinite loop starts, causing the
StackOverflow.
During the tab switch of the screen that works, the line 393 of
Objects.java is never reached, meaning that this screen was not serialized,
right? This code is only reached during a tab switch of the screen that
throws StackOverFlow exception.

Hi,
It seems that this could be an OSGi related issue. We have the similar
problem in our applications.
You can look at the thread: Wicket + OSGI + Session (november 2007).
Then Sebastiaan gave me a tip that this can be ClassNotFoundException:
It's probably a ClassNotFoundException on deserialization which gets
eaten by ObjectInputStream (there's a bug report at Sun for this). To be
sure you can debug trapping on ClassNotFoundException (caught and uncaught)
when this problem occurs.
However, since it's in a page you can easily fix this one: either
upgrade to trunk and implement your own IClassResolver and register it with
the application, or write your own IObjectStreamFactory implementation and
register it with the Objects class.
In either case, have a look at the DefaultObjectStreamFactory to see how
to write a hook to look up classes in an ObjectInputStream implementation
(resolveClass method).
Inside OSGI environment each bundle has its own class loader, so this
could leeds to problem when you try to use in your app a class defined in
another bundle.
I've solved this problem by implementing my own IClassResolver. The
default Wicket DefaultClassResolver is a final class, so we must make a copy
of it and make a little change at the end of resolveClass method.
The default implementation (DefaultClassResolver):
synchronized (classes)
{
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
if (loader == null)
{
loader =
DefaultClassResolver.class.getClassLoader();
}
clazz = loader.loadClass(classname);
}
When there is a ClassLoader attached to the current thread as context
class loader, then Wicket uses it. The problem is under OSGi, that the
related class (with classname) can be located inside another bundle and can
be loaded by another class loader, not this from current thread. So
DefaultClassResolver fails to find this class. The solution is to try in
such situation use the class loader which loads DefaultClassResolver class
(= which loads all Wicket classes). In our CustomClassResolver this block
was changed to something like this:
synchronized (classes) {

Hi!
In my application a user should be able to connect keywords to a
datasheet.
When clicking the link add keywords 10-20 textfields should appear and the
user can enter data to
the fields.
#1
textField
#2
textfield
..
How can I handle this like an array in wicket? I do not want to add 20
textfields by hand.

Re: UploadProgress Bar and cancel button
I doubt its a workerthread issue, it calls the submit form even though the default form processing is set to false.

Re: java.io.StreamCorruptedException: invalid type code: 29
passing 0 instead of -1 is definitely not the solution. This can
result in wrong page version set to other page references. I wish you
could provide a quickstart that reproduces the problem. It looks like
a bug in wicket but so far I'm not able to reproduce this behavior.

I think I've found the solution for my StreamCorruptedException problem.
Inside the org.apache.wicket.Page, there is a constant LATEST_VERSION which
value is -1. In my application, the versionNumber passed as parameter to
the method getVersion(final int versionNumber) inside Page is never -1, the
initial versionNumber of a page is always 0. When this versionNumber is
different from 0, the versionManager object inside Page is not null, so the
flow goes to the else block inside the getVersion() method.
If LATEST_VERSION is -1, the flow of my application is always going to the
if block below, never to else block, as my versionNumber is always = 0, so
depending on the versionNumber, no page will be recovered, which was leading
to the StreamCorruptedException, maybe because wicket was trying to
de-serialize the wrong version of my page.
if (versionNumber != LATEST_VERSION) {
page = versionManager.getVersion(versionNumber);
}
else {
page = versionManager.getVersion(getCurrentVersionNumber());
}
I've changed LATEST_VERSION value to 0, and now my application works
perfectly. Are these assumptions correct? Does anytime versionNumber assumes
the -1 value?

I debugged my application and it really doesn't have a
ClassNotFoundException eaten by ObjectInputStream. I compared the flow of
two screens of my application, one that works and another that doesn't:
1) The line 298 of SecondLevelCacheSessionStore =
getLastPage().getVersion(versionNumber) is returning the correct page,
because inside the getVersion() method, the versionManager object is null.
In this case, the screen that I'm testing works perfectly.
2) For the screen that throws the StackOverFlow and
StreamCorruptedException, for some reason the versionManager object is not
null, and it returns a null page object.
Another strange thing is that after the line 393 of Objects.java = return
ois.readObject(); = while debugging it using Eclipse, after this method
call the flow goes straight to the line 363 of AbstractPageStore.java,
without entering the finally block. So, an infinite loop starts, causing
the
StackOverflow.
During the tab switch of the screen that works, the line 393 of
Objects.java is never reached, meaning that this screen was not serialized,
right? This code is only reached during a tab switch of the screen that
throws StackOverFlow exception.
What defines if a page should be serialized/deserialized? Does anyone know
what could be causing these problems?

Hi,
It seems that this could be an OSGi related issue. We have the similar
problem in our applications.
You can look at the thread: Wicket + OSGI + Session (november 2007).
Then Sebastiaan gave me a tip that this can be ClassNotFoundException:
It's probably a ClassNotFoundException on deserialization which gets
eaten by ObjectInputStream (there's a bug report at Sun for this). To be
sure you can debug trapping on ClassNotFoundException (caught and
uncaught)
when this problem occurs.
However, since it's in a page you can easily fix this one: either
upgrade to trunk and implement your own IClassResolver and register it
with
the application, or write your own IObjectStreamFactory implementation
and
register it with the Objects class.
In either case, have a look at the DefaultObjectStreamFactory to see how
to write a hook to look up classes in an ObjectInputStream implementation
(resolveClass method).
Inside OSGI environment each bundle has its own class loader, so this
could leeds to problem when you try to use in your app a class defined in
another bundle.
I've solved this problem by implementing my own IClassResolver. The
default Wicket DefaultClassResolver is a final class, so we must make a
copy
of it and make a little change at the end of resolveClass method.
The default implementation (DefaultClassResolver):
synchronized (classes)
{
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
if (loader == null)
{
loader =
DefaultClassResolver.class.getClassLoader();
}
clazz = loader.loadClass(classname);
}

Error using JUnit: Can't instantiate page using constructor
Greetings, all,
I am getting started with Wicket and just wrote my first simple JUnit test
for a small Wicket application (taken from the Wicket in Action book). The
test is:
public class TestIndexPage {
@Test public void labelContainsHelloWorld() {
WicketTester tester = new WicketTester();
tester.startPage(Index.class);
tester.assertContains(Gouda);
}
}
When I run it, I get the following:
[junit] 407 [main] ERROR org.apache.wicket.RequestCycle - Can't
instantiate page using constructor public com.cheesr.Index()
[junit] org.apache.wicket.WicketRuntimeException: Can't instantiate page
using constructor public com.cheesr.Index()
I have searched this group but not found any relevant solutions. I am too
new to Wicket to understand how to diagnose this problem.
I have written a page with a more complete description of my error,
including a link to a .zip file which you can use to reproduce the error
quickly and which includes complete sources at:
http://code.google.com/p/hackystat-ui-wicket/wiki/WicketJUnitError
I would be most grateful for any help you could provide. I am a refugee
from the Stripes/Struts/GWT world and am quite excited by the approach taken
in Wicket.
Thanks very much,
Philip Johnson

Re: Error using JUnit: Can't instantiate page using constructor
look at the stacktrace, the root cause is:
Caused by: java.lang.ClassCastException:
org.apache.wicket.util.tester.WicketTester$DummyWebApplication cannot
be cast to com.cheesr.CheesrApplication
in your page you are trying to cast application to cheesrapplicatio,
but by default wickettester uses its own internal application class,
so you should do
WicketTester tester=new WicketTester(new CheesrApplication());

wicketstuff-push-examples compilation error
Hi, Wicket users,
I thought I'd examine wicketstuff-push, since I could use push on a
project. After a fresh check-out of wicketstuff-push,
wicketstuff-push-examples, and wicket-stuff-dojo, I found that
wicketstuff-push-examples wouldn't compile. Keep in mind I just
starting looking at this code, but I made the following change to
class WicketAbstractPushChat to get it to compile (and now the
examples do appear to work):
Replace:
final IPushTarget pushTarget = getPushService().installPush(this);
CHAT_ROOM.addListener(new ChatListener() { ... });
With:
final IPushInstaller pushInstaller = new IPushInstaller() {
public void install(Component component, final IPushTarget pushTarget) {
CHAT_ROOM.addListener(new ChatListener() {
public void onMessage(Message msg) {
if (pushTarget.isConnected()) {
pushTarget.appendJavascript(document.getElementById(' +
chat.getMarkupId() + ').innerHTML += ' + msg + br/');
pushTarget.trigger();
} else {
CHAT_ROOM.removeListener(this);
}
}
});
}
};
getPushService().installPush( this, pushInstaller );
Does that make sense? Again it appears to work but there are a ton of
errors saying TimerPushService is not serializable.
Otherwise, looks pretty cool and I hope to do more experimenting next week.
HTH,
Enrique
