(Un-)deployment woes on Tomcat (and JBoss)
Hi, I'm having problems with deployment/undeployment of Wicket apps on Tomcat (and also JBoss, though I think it's related to the fact that it embeds Tomcat). Basically, in both cases undeployment comes back with an Exception, leaving the server in a dirty state and I have to restart the server every time. This has been mentioned in both the user and developer lists, but with no reply: http://old.nabble.com/java.lang.NoClassDefFoundError:-org-apache-wicket-util-lang-PropertyResolver-tc26191924.html http://old.nabble.com/Weird-error-on-shutdown...-td18907685.html The problem manifests only when deploying EXPLODED wars (with a single packaged WAR file, the problem goes away). It can be easily reproduced as follows: 1) Create an instance of the quickstart archetype (http://wicket.apache.org/quickstart.html). Let's say you used the default values so the artifact id is myproject from here on. Use the latest 1.4.7 version of Wicket (though I've tried with all previous versions up to 1.4.4 and the result is the same; the reference above uses version 1.4-m2, so it must be surprisingly old). 2) Create an EXPLODED web archive (war) with mvn war:exploded 3) Move the exploded war folder (myproject-1.0-SNAPSHOT) to the deployment folder (server/xxx/deploy for JBoss or webapps) 4) Undeploy by moving the exploded war folder (myproject-1.0-SNAPSHOT), OUT of the deployment folder You will get a stack trace that basically ends up in a ClassNotFound exception when the Wicket filter is cleaning up: java.lang.NoClassDefFoundError: org/apache/wicket/util/lang/PropertyResolver at org.apache.wicket.Application.internalDestroy(Application.java:952) at org.apache.wicket.protocol.http.WebApplication.internalDestroy(WebApplication.java:527) at org.apache.wicket.protocol.http.WicketFilter.destroy(WicketFilter.java:179) at org.apache.catalina.core.ApplicationFilterConfig.release(ApplicationFilterConfig.java:267) This is a huge annoyance, because re-deployment of the application does not work; if you try to deploy it again, JBoss fails with: org.jboss.deployers.spi.DeploymentException: Web mapping already exists for deployment URL file:/F:/ade_ws/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_5.1_(default)/deploy/myproject-1.0-SNAPSHOT/ at org.jboss.web.tomcat.service.deployers.TomcatDeployment.performDeployInternal(TomcatDeployment.java:187) Basically, you must restart the entire JBoss server. In a production environment it means you can't upgrade your wicket applications without affecting other applications (though you can get away if you don't use an exploded WAR folder). In a developer environment it's totally counter-productive: you need the exploded format and restaring JBoss every time is quite irritating. The Eclipse WTP adapter runs in exploded mode which basically makes working with Eclipse a nightmare. I am using JDK1.6 (I use 1.6.0_18) and either JBoss5.1 or Tomcat 6.0.26 (or 6.0.18 or 5.5.28 which I also tried). My system is running Windows 7 and NTFS (it may be relevant to the way the file-system handles moving folders). Last notes: 1) I had a look at the code. It seems that Wicket tries to use weak references to facilitate a thorough clean-up of the JVM by garbage collection after the application is undeployed. This may be related, as it appears to me as if the class loader used by the application is no longer available during clean-up. I think there's some class-loading magic going on, probably the thread's context class loader is being switched, which ends up in the destroy() method not having access to wicket. 2) Jetty does not seem to have any problems, so it must be something in the way Tomcat works. 3) The complete stack trace in my case (Win7, JDK1.6.0_18-win32, JBoss5.1, Wicket1.4.7) is: java.lang.NoClassDefFoundError: org/apache/wicket/util/lang/PropertyResolver at org.apache.wicket.Application.internalDestroy(Application.java:952) at org.apache.wicket.protocol.http.WebApplication.internalDestroy(WebApplication.java:527) at org.apache.wicket.protocol.http.WicketFilter.destroy(WicketFilter.java:179) at org.apache.catalina.core.ApplicationFilterConfig.release(ApplicationFilterConfig.java:267) at org.apache.catalina.core.StandardContext.filterStop(StandardContext.java:3818) at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4605) at org.apache.catalina.core.ContainerBase.destroy(ContainerBase.java:1175) at org.apache.catalina.core.StandardContext.destroy(StandardContext.java:4705) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at
Re: (Un-)deployment woes on Tomcat (and JBoss)
Ok, I've pinpointed the underlying cause. Indeed, the file is simply
removed before the destroy() method has a chance to clean up. I verified
this by using this ugly hack:
1. Adding a field:
private InputStream wicketJarProtector;
2. In WicketFilter.init() I open the wicket jar to protect it from
deletion:
wicketJarProtector =
filterConfig.getServletContext().getResourceAsStream(/WEB-INF/lib/wicket.jar);
3. In WicketFilter.destroy() I close the file handle:
wicketJarProtector.close();
This prevents the file from being deleted, undeployment completes
successfully.
I'm not sure how to properly fix this... Any ideas?

I could keep going by adding references to such classes until every

for some reason, there is no more access to wicket.jar in
WEB-INF/lib. I added debugged through the code and the weird thing
is that it's the same class-loader AND the same thread (JBoss'
[HDScanner] thread). So it should be able to load these classes. A
look at the bottom of the stack trace reveals this (notice that there
is a DelegatingHandler to wicket.jar and all packages for wicket

How do I provide digit-only IDs to make childs safe?
Hi, I'm a new Wicket user who is also getting familiar with the GMap2 module from wicket-stuff. I'm using the geocode example as a basis for creating a form which allows you to search for a location and set the map viewport to display it: https://wicket-stuff.svn.sourceforge.net/svnroot/wicket-stuff/trunk/wicketstuff-core/gmap2-parent/gmap2-examples/src/main/java/wicket/contrib/examples/gmap/geocode/ The code works, but every time I search for a place I get a warning: WARN - AbstractRepeater - Child component of repeater org.apache.wicket.markup.repeater.RepeatingView:content has a non-safe child id of [STRING_SEARCHED]. Safe child ids must be composed of digits only. The [STRING_SEARCHED] is whatever I typed in the text field (e.g. Barcelona, Spain or Athens, Greece). So apparently, GMap2 sets an ID somewhere using the text field's value, violating some Wicket expectation that such IDs should be composed using digits only.

Beginner localization question
Hi,
How can I have Wicket resolve a key to some localized messages with my
own code at runtime? The reason I ask is because I have this use case:
1) I use Java enumerations to strongly-type a RadioChoice control:
public enum RadioOptions { ONE, TWO, THREE }
2) I strongly-type a RadioChoice control:
public SomePage() {
...
RadioOptions radio = RadioOptions.ONE;
RadioChoiceRadioOptions r = new RadioChoiceRadioOptions(...,
Arrays.asList(RadioOptions.values()));
...
3) Define localized messages in the MyWicketApplication_xx.xml file:
entry key=ONEFirst option text/entry
4) Overload toString() as follows:
public enum RadioOptions {
ONE, TWO, THREE;
public String toString() {
String key = this.name(); // ONE, TWO or THREE
return .; // how do I ask Wicket to search for
the localized message?
}
}

Another beginner localization question
Hi,
I'm using a wicket:message tags, property files and a ChoiceRenderer
to allow users to switch the Locale. My ChoiceRenderer overrides
wantOnSelectionChangedNotifications() to have the browser send a Locale
change event to the server and when this call returns, all
wicket:message content is updated to match the new locale's messages.
This all works fine. However, I also have a DatePicker JQueryUI
component component on my page which needs to be adjusted. This is done
by having the browser execute the JavaScript:
script type='text/javascript'
$(function() {
$.datepicker.setDefaults($.datepicker.regional['_[LOCALE]_']);
});
/script
Is it possible to have the browser to execute some dynamically-generated
JavaScript using the ChoiceRenderer's onSelectionChanged() event?
Thanks in advance.

AjaxFormComponentUpdatingBehavior and id attribute
Hi, When I add an AjaxFormComponentUpdatingBehavior to a component (a TextFieldString in particular though I don't think that matters), Wicket assigns an HTML id attribute to the component by taking the wicket:id value I specified and appending a character. So, if my original HTML had: input wicket:id=birthday id=x type=text / At runtime I get: input wicket:id=birthday id=birthdayX type=text / This messes up some static CSS/Javascript I have in the page, which relies on locating hte component using its original id.

GMap2 from wicketstuff: how to dynamically resize?
Hi,
I am unsing GMap2 from WicketStuff
(http://wicketstuff.org/confluence/display/STUFFWIKI/wicket-contrib-gmap2)
and need to display a map in a pop-up dialog. I use JQuery for the
dialog. When the Dialog comes up, the map's viewport is offset in
relation to the window and only the cross-section of the map's position
(starting outside the dialog window) and the actual pop-up window is
being drawn. For example, assume the map starts at absolute position 0,0
with as size of 600,400 and the dialog is shown at absolute position
300,200 with size 600,500: Only the region (300,200 - 600,400) is drawn.
This is probably because the dialog is not shown when the GMap2
javascript calculates its position, so I need to call the
checkResize() method on
http://code.google.com/apis/maps/documentation/reference.html#GMap2 that
is created by the WicketStuff control. Problem is, I can't get to the
Javascript object underlying the wicketstuff representation. I'm trying

Re: GMap2 from wicketstuff: how to dynamically resize?
Ok, looking at the sources, I found that WicketStuff adds a
WebMarkupContainer which is used for the actual map. Unfortunately, it
hides this object from its client code, so there's no way to access it
and call gmap2container.getMarkupId(). It does however assign the
class gmap to the container. So I got around this using this ugly hack:
myDialog.setOpenEvent(JsScopeUiEvent
.quickScope(
var mapCtrl = $('.gmap').attr('id');\n +
dom.getElementById(mapCtrl).checkResize();
)
);
Works if there's only one map in the page...

Re: GMap2 from wicketstuff: how to dynamically resize?
I guess the description was rather complicated...
Anyway, the thing is: the Map2 class from the Google Maps API,
apparently looks at the location and size of a div tag used as its
canvas, to do some setup at page load time. When the div it targets is
hidden, its size/position attributes are apparently not correct. Thus,
when the div becomes visible, the Map2 object has the incorrect
coordinates and size (calculated during the page load) and draws itself
in a messed up state.
I came across this because I had my map inside a pop-up dialog (from
JQueryUI) which is initially hidden and appears at the center of the
browser window when the user clicks a button.
Anyway, to have the Map2 control re-calculate and re-draw itself, you
need to call its checkResize() method. To do that, I needed a
reference to the JavaScript object holding the map. Since I was using
the module from wicket-stuff, I was looking for a way to get to that
javascript object (from my Java code), so that I may dynamically
generate JavaScript code that calls checkResize() when the dialog is
opened and becomes visible.
Anyway, the solution in my previous post was wrong. It was a way to get
to the div tag that is used as the map canvas. No point in calling
checkResize() on that. What I needed was the Map2 JavaScript object that
is used to control the map.
The correct answer (now that I got it working) is:
myJQueryDialog.setOpenEvent(JsScopeUiEvent
.quickScope(var mapCtrlId = $('.gmap').attr('id');\n
+ Wicket.maps[mapCtrlId].map.checkResize();\n
));
The Wicket.maps[] object is managed by the code in wicket-gmap.js
from the wicket-stuff module for maps.
Reading back, I am not sure this explanation is simpler than my previous
one, but hey, it IS Sunday afternoon...

AutoCompleteTextField: converter seems to be ignored
Hi,
I'm using AutoCompleteTextFiled with Wicket 1.4.9. My model is a POJO
that is specified as a generic:
searchTextField = new AutoCompleteTextFieldSomePOJO(...
Therefore I return an Iterator of such POJOs with:
protected IteratorSomePOJO getChoices(String input) {
I'm trying to customize the text displayed (which defaults to
SomePOJO.toString()) using a converter:
public IConverter getConverter(Class? type) {
System.err.println(Looking up converter for: +
type.getCanonicalName());
if (SomePOJO.class.isAssignableFrom(type)) {
return new IConverter() { ...
However, wicket never calls the getConverter() method and simply uses
SomePOJO.toString() to retrieve the text for the choices. What am I
doing wrong?

Should Logger classes be transient?
Hello, I'm using SLF4J and was wondering whether pages should declare: private transient final Logger log = LoggerFactory .getLogger(SomePage.class); as members.

Mixing static with dynamic items in the same list
Hello,
I have a page with a simple HTML unordered list (ul), where part of the
list items are static, whereas the rest of them are dynamic. To that end,
I've injected a span tag at the end of the static items, adding a
ListView in order to fill in the dynamic part, as follows:
HTML
-
ul
li
a href=#First static item/a
/li
li
a href=#Second static item/a
/li
span wicket:id=dynamicItems
li wicket:id=dynamicListItem/li
/span
/ul
Code
-
ListView dynamicItems = new ListView(dynamicItems, someList) {
protected void populateItem(ListItem item) {
Label link = new Label(dynamicListItem,
a href='...' + item.getModelObject() + /a);
link.setEscapeModelStrings(false);
item.add(link);
}
};
This achieves what I need, but keeps the span tags in place (causing
some unrelated CSS to miss its target elements). So, the HTML that is
produced is as follows...:
ul
li
a href=#First static item/a
/li
li
a href=#Second static item/a
/li
spanliFirst dynamic item/li/span
spanliSecond dynamic item/li/span
spanliThird dynamic item/li/span
/ul
But what I want to achieve is the following clean output (notice the
absence of span tags):
ul
li
a href=#First static item/a
/li
li
a href=#Second static item/a
/li
liFirst dynamic item/li
liSecond dynamic item/li
liThird dynamic item/li
/ul
How can I achieve this?

[MIGRATE 1.5] NPE trying to use JavaScriptTemplate
Hi,
I've just started preparing for 1.5 and have been modifying my code in
order to conform with the new API. I've managed to get my application to
compile and launch, but in my first attempt to render a page I get an NPE
as follows:
java.lang.NullPointerException
at
org.apache.wicket.util.template.TextTemplateDecorator.setLastModified(TextTemplateDecorator.java:195)
at
org.apache.wicket.util.resource.AbstractStringResourceStream.init(AbstractStringResourceStream.java:76)
at
org.apache.wicket.util.resource.AbstractStringResourceStream.init(AbstractStringResourceStream.java:62)
at
org.apache.wicket.util.template.TextTemplate.init(TextTemplate.java:42)
at
org.apache.wicket.util.template.TextTemplateDecorator.init(TextTemplateDecorator.java:52)
at
org.apache.wicket.util.template.JavaScriptTemplate.init(JavaScriptTemplate.java:42)
at assets.wicket.ovimaps.OviMap.renderHead(OviMap.java:46)
at org.apache.wicket.Component.renderHead(Component.java:2644)
Now this part of the code is an adaptation of what used to be a
template-based javascript header contribution as follows:
add(TextTemplateHeaderContributor.forJavaScript(OviMap.class,
OviMap.js, model));
The above has been removed from the component constructor (where it used
to be) and replaced with the following in code inside my component:
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
JavaScriptTemplate template = new JavaScriptTemplate(
new PackagedTextTemplate(OviMap.class, OviMap.js));
response.renderString(template.asString(model.getObject()));
}
What am I doing wrong?
P.S. I am using 1.5-rc2.

Re: Understanding Wicket 1.5 page mapping
Hello,
Could you post some pseudo-code on what your request mapper looks like? I
have a similar use-case but I wasn't able to follow. I created a
MyRequestMapper class that wraps the default root mapper:
setRootRequestMapper(new MyRequestMapper(getRootRequestMapper()));
public class MyRequestMapper implements IRequestMapper {
private final IRequestMapper wrappedMapper;
public MyRequestMapper(IRequestMapper wrappedMapper) {
this.wrappedMapper = wrappedMapper;
}
...
mapRequest()
mapHandler()
getCompativilityScore()
...
}
Currently I delegate to the wrapped handler. What I would like to do is
peek at the URL (i.e. request.getUrl()), then decide based on some logic
which page to render. However, mapRequest() returns an IRequestHandler.
I would've liked to return same page class like this:
@Override
public IRequestHandler mapRequest(Request request) {
ListString segments = request.getUrl().getSegments();
if (existsPerson(segments.get(0)) {
== return PersonPage.class;
} else if (existsProduct(segments.get(0)) {
== return ProductPage.class;
}
return wrappedMapper.mapRequest(request);
}
How would I go about doing that?

[MIIGRATE 1.5] Where is getSharedResources().putClassAlias(...)
Hello,
Here's my next question regarding migration to 1.5. I used to publish
dynamic image resources (retrieved from DB) as follows:
protected void init() {
super.init();
getSharedResources().putClassAlias(org.apache.wicket.Application.class,
global);
getSharedResources().add(images, new ImageResources());
}
The above would let my image resource reply to the URL:
http://host/resources/global/images?params=...
In 1.5, the SharedResources class no longer has a putClassAlias()
method, so apparently there's something new.
How do we go about doing this with 1.5?
Thanks in advance!

Nesting RepeatingView components: Possible attempt to embed component(s) error
Hello, I want to add menus (as in a menu bar with drop-down menus) on my pages. In order to achieve that, I must use a nested RepeatingView (see further down for the explanation). What I need (and don't know how to do) is to be able to have markup like this: ul class=web-menu li wicket:id=menuBarChoices ul li wicket:id=menuBarChoiceItems/li /ul /li /ul In my code, I would use RepeatingView to generate a number of list-items (menuBarChoices) which would be rendered as a menu bar. In addition I would need to create a NESTED RepeatingView per each of the menuBarChoices, to generate a number of list-items (menuBarChoiceItems). These would be rendered as a drop-down menu when the user hovers over the respective menu bar choice. I tried to do that, but Wicket catches my attempt to nest the RepeatingView components and politely explains that the outer component discard its content, therefore the nested embedded component can no longer be used for dynamic content. The message is as follows: Last cause: Expected close tag for 'li wicket:id=menuBarChoices' Possible attempt to embed component(s) 'li wicket:id=menuBarChoiceItems' in the body of this component which discards its body. Ultimately, I need Wicket to produce something like this: ul class=web-menu li Menu1 ul liMenu Subitem 1/li liMenu Subitem 2/li /ul /li li Menu2 ul liMenu Subitem 1/li liMenu Subitem 2/li /ul /li /ul How do I go about doing that? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Nesting RepeatingView components: Possible attempt to embed component(s) error
Hi, I actually managed to get around this by creating a component called DropDownMenu with the following HTML: html xmlns:wicket body wicket:panel span wicket:id=menu/span ul li wicket:id=menuChoices/li /ul /wicket:panel /body /html The DropDownMenu.java code creates a repeating view (the nested one) and adds the menuChoices. Then, I simply add instances of new DropDownMenu(...) to the outer RepeatingView which I've also converted into a separate MenuBar component.

Re: Could not resolve class: my.domain.favicon.ico
Hello Rene,
I understand that you probably currently DON'T have a favicon for your
site and you are disturbed by the browser's attempt to fetch it.
First of all, you should read http://en.wikipedia.org/wiki/Favicon to see
what this is about. It's the icon that browser use to decorate the address
bar, bookmarks menu, etc. You are NOT required to have one. If you don't
have one, the browser simply shows a generic icon in those places. The
browser will however try to fetch it anyway (most browsers will try to
retrieve favicon.ico from the root folder of the site), so it is normal
for you to get an error in your web server's logs, reporting a miss when
the browser attempts to fetch it. In your case, as Igor pointed out, due
to the mounting you performed the request will end up searching for the
result within your home page package.
If you do add such an icon, I would recommend putting the icon file in
src/main/webapp so that it is accessible from the root location.
Alternatively, point to the actual URL where it can be found (e.g. inside
the home page package) using the link tag above.You can change the
location from which to fetch the favicon using a link tag in your page
header, as follows:
link rel=shortcut icon href=http://example.com/myicon.ico; /
More information can be found here:
http://en.wikipedia.org/wiki/Favicon#Accessibility
Regards,
Alexandros

OK, I have imagined that. But it seems mountPackage does also mount

If I mountPackage everything the LoginForm is available.
If I do mountPage my LoginForm is not available after I submit (same

The HomePage does not have this component at all.
Even when I do:
mountPage(HomePage)
mountPackage(LoginPage)
it changes.
Only when i mountPackage everything it seems to work.
Btw, HomePage is in the root folder, while LoginPage is in a subfolder.
mountPage() mounts just a single page without any knowledge about

The docs told me I could mount a whole package. As subfolders are not

loadProperties load a property file from web-inf as the name

Re: [osgi] package org.apache.wicket.request exported either from core and request packages
I would reverse the question and ask: why was wicket broken into multiple packages in the first place? I assume there are use cases where: - someone would need only the content of wicket-core and none of the extras - someone would need only wicket-core + wicket-request - someone would need only wicket-core + wicket-util - ... I suppose the above scenarios actually were needed and that lead to the split. If there is no practical use in having Wicket broken into multiple packages, then why do it in the first place? In any case, since I assume there is a reason for the split, I'd say that the same use-cases that apply in a non-osgi environment, also apply for the OSGi case. Projects that only need wicket-core should load only that and nothing else. Other than being leightweight for such cases, I don't see a reason why an uber-jar won't work. Now, assuming that this split is what the community and the developers want, it should be offered for both non-OSGi as well as OSGi environments. This means that we simply need to make sure there is at least one package that is unique per bundle and instruct OSGi people to do package-based imports using the non-common packages. For example, in Daniele's case, the package used in org.apache.wicket.request. However this exists in both the wicket-core and wicket-request bundles, causing the problem. A different package should be used. @Daniele: try importing org.apache.wicket.request.flow, which only exists in wicket-request. This should get you the correct bundle, without having to modify the distribution. Alternatively, you can import specific bundles rather than packages. Having said that, for what it's worth, I agree with Daniele that since this is a major release, it is a golden opportunity to do some OSGi-friendly package-renaming.

Re: [MIIGRATE 1.5] Where is getSharedResources().putClassAlias(...)
Just for future reference:
As explained by Martin in the ticket, turns out that now one must:
mountResoruce(/path/to/resource, ResourceReference);
So in my case it's simply:
mountResource(imgres, new ResourceReference(Application.class,
imgres) {
private static final long serialVersionUID = 1L;
ImageResources imgres = new ImageResources();
@Override
public IResource getResource() {
return imgres;
}

Table repeater: repeat across row AND column
Hello,
I am trying to create a web page that lists contact addresses in a table.
My repeater can easily lay out one address per row, but I need to be able
to list 2 addresses per row (actually, ideally I'd like to list N
addresses per row). The problem is that ListView's operation
[populateItem()] only provides you with one item to work with. So with
this markup:
html xmlns:wicket
body
wicket:panel
table wicket:id=addressesTable style=width: 100%;
tr wicket:id=addresses
td wicket:id=address style=width:
50%;/td
!--
I NEED ANOTHER CELL LIKE THE
ONE ABOVE HERE
td wicket:id=address2 style=width:
50%;/td
--
/tr
/table
/wicket:panel
/body
/html
If I uncomment the second cell above, I need to be able to access the
next item, something like:
final ListViewAddress rowContainer = new ListViewAddress(
addresses, model) {
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItemAddress item) {
Address a = item.getModelObject();
AddressPanel ap = new AddressPanel(address,
new CompoundPropertyModelAddress(
new
AddressLoadableDetachableModel(a.getId(;
item.add(ap);
/*
// DOES SUCH AN API EXIST?
//
if (item.hasNext()) {
item.next();
a = item.getModelObject();
AddressPanel ap2 = new AddressPanel(address2,
new CompoundPropertyModelAddress(
new
AddressLoadableDetachableModel(a.getId(;
item.add(ap2);
}
*/
}
};
My only solution currently is that I convert the list of addresses to a
list of address tuples (pairs), so that I am able to repeat over pairs of
addresses. In short, I am just wondering if there is a better way to do
this rather than (pseudocode):
ListAddress addresses = myRepository.loadAddressList();
ListTupleAddress,Address addressPairs = convertToPairs(addresses);
// Make the above repeater iterate over ListTupleAddress,Address
having access
// to two addresses per repetition
Any pointers on this? Thank you in advance.

INullAcceptingValidator behavior
Hello, 1) I have a custom validator that implements INullAcceptingValidator. 2) A TextField component in my form has validator (1) attached to it and is setRequired(false). 3) When I submit my form with the text input empty, the validator does NOT get called. It only gets called if there is a value with the HTML input field. I was expecting that the validator would be invoked upon submission even if the text field is empty, in order to validate tha value null. At least this is what I understand as far as INullAcceptingValidator goes. However, this does not appear to happen. Instead, Wicket goes on to call the form's onSubmit() method with the value null inside my model.

Re: Xforms Controls within Wicket Application
Hello, First of all, there is ambiguity in your question. I'm not sure how the above would tie into a wicket-specific question, unless you want to create an XForm--XHTML renderer/processor using Wicket as the underlying technology (which is not a good idea IMHO). In any case: 1) Are you asking whether Wicket can be used to render XForms files (as in the the XForms specification at http://www.w3.org/TR/xforms11/). In this case, the answer is NO, I'm not aware of such an XForm renderer. You could create a custom Wicket component that is given an XForm definition document and uses it to render an XHTML page, but that is a lot of work (and probably not a very efficient way to do it, as you would ideally use XSLT or something along those lines to do XML--XML transformation. There are available open-source tools like Orbeon (see http://www.orbeon.com/) which can give you this kind of functionality (including processing of the XForm submission). Now, regarding the online/offline issue: 2) Do you have a rich client application that can render the XForms (e.g. using Swing) and allow the user to save such forms locally? In that case, you would need to write code that submits the forms when the rich client has network access. The submission should probably go to some servlet (e.g. an Orbeon-managed URL). Again, I don't think this would be wicket-related. 3) If you have a web-based application for this (e.g. a bundled Tomcat running on the user machine, which they access via the browser) then the principle is a combination of (1) and (2): You would need: a) to render the forms using something like Orbeon to present HTML to the browser b) to store the form submission to the local FS (or a locally running DB which could be something like Derby) c) to implement an uploader where the user can send locally saved forms to a central server (same as what I talked about in (2) above) On 11/7/2011 4:09 μμ, sramay wrote: Hi, Rendering a document in the Xforms or storing it in a database is as you have suggested ok. The issue is there when you have xform controls inside a wicket application instead of HTML document(form) and take the imput and stores them into a database. Am I explaining my position clearly ?

[Migration 1.5]: exception handling in request cycle
Hi,
I'm trying to plug into the new request cycle processor of 1.5-RC5.1. I am
following the instructions in the wiki page, but I seem to have run into some
out-of-date info. So, according to:
https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-RequestCycle:
1) I must create a class implementing IRequestCycleListener
2) I must bind my listener during application init() with
getRequestCycleListeners().add(...);
My problem is that previously when we extended the WebRequestCycle, we would
preserve the default exception handling by using:
@Override
public Page onRuntimeException(Page page, RuntimeException e) {
return super.onRuntimeException(page, e);
}
Now, the wiki page claims that in my listener I can:
public void onException(Exception ex) { /*do nothing*/} However, the new
listener interface forces you to return a handler (IRequestHandler), it does
not
return void as claimed in the wiki. So what do I do to return something that
will tell Wicket to proceed with its default Exception handling? The actual
signature is:
public IRequestHandler onException(RequestCycle cycle, Exception ex) {
// what do I return in order not to interfere?
}

Re: [Migration 1.5]: exception handling in request cycle
Ok, thx.
In terms of improving the wiki, I guess my source of confusion was that I was
reading:
https://cwiki.apache.org/confluence/display/WICKET/Migration+to+Wicket+1.5#MigrationtoWicket1.5-RequestCycle
I fixed the signature of onException(...) and also added some comments in the
sample request listener implementation (indicating that you may return null).
Finally, I added a link to the page you directed me to in the Exception
Handling section immediately afterwards which only mentioned the exception
mapper. This should help one find that the mapper is used only in case all of
the listeners return null.
Alex.

Basic l10n / i18n question: must page be re-rendered?
Hello,
I have written a locale selector by extending DropDownChoice (you can
see the essential stuff of the implementation below). The problem is
that when the user changes the locale, the page needs to be re-rendered
using the newly selected locale. This does NOT happen. Instead, only the
select input box seems to be refreshed to use the new locale,
whereas the rest of the page content is still rendered using the
previously selected locale. However, the locale has been changed in the
Session which can be seen when the user navigates to another page (e.g.
by clicking on a link), as the new page is rendered using the
newly-selected locale.
So, how can I force the current page to be re-rendered?
Implementation of my locale selector is as follows:
Markup: select wicket:id=localeSelection/select
Component code:
public class LocaleDropDown extends DropDownChoiceLocale {
//...
public LocaleDropDown(final String id, final ListLocale choices) {
// ...
setModel(new IModelLocale() {
public Locale getObject() {
return getSession().getLocale();
}
@Override
public void setObject(Locale locale) {
getSession().setLocale(locale);
// need something here to tell wicket to refresh the
entire page?
}
});
// ...
}
@Override
protected boolean wantOnSelectionChangedNotifications() {
// post an event when user changes the selected value in the
drop-down box
return true;
}
}

Re: Basic l10n / i18n question: must page be re-rendered?
Hi Gregor,
I've found a way to do this by manipulating the request cycle. However,
it will only work if you don't mind losing any page state, as it
generates a new page rendering. I do this by overriding
onSelectionChanged(...) of the DropDownChoiceLocale as follows:
@Override
protected void onSelectionChanged(Locale newSelection) {
super.onSelectionChanged(newSelection);
// the following tells wicket to instantiate a new page using
the current page's class
getRequestCycle().setResponsePage(getPage().getClass());
}
Maybe a more knowledgeable user could suggest a better alternative?

Just to add to this that the following will work for pages with parameters:

super.onSelectionChanged(newSelection);
// the following tells wicket to instantiate a new page using
the current page's class
getRequestCycle().setResponsePage(getPage().getClass(),

be re-rendered using the newly selected locale. This does NOT
happen. Instead, only the select input box seems to be refreshed
to use the new locale, whereas the rest of the page content is still
rendered using the previously selected locale. However, the locale
has been changed in the Session which can be seen when the user
navigates to another page (e.g. by clicking on a link), as the new
page is rendered using the newly-selected locale.
So, how can I force the current page to be re-rendered?
Implementation of my locale selector is as follows:
Markup: select wicket:id=localeSelection/select
Component code:
public class LocaleDropDown extends DropDownChoiceLocale {
//...
public LocaleDropDown(final String id, final ListLocale
choices) {
// ...
setModel(new IModelLocale() {
public Locale getObject() {
return getSession().getLocale();
}
@Override
public void setObject(Locale locale) {
getSession().setLocale(locale);
// need something here to tell wicket to refresh the
entire page?
}
});
// ...
}
@Override
protected boolean wantOnSelectionChangedNotifications() {
// post an event when user changes the selected value in the
drop-down box
return true;
}
}
-- Kind regards, Alex

Cookies and RestartResponseException
Hi, I am using CookieUtils to store a cookie. Here's the catch though: after setting the cookie, I want to redirect the user to a new page, so that is followed immediately by a RestartResponseException: new CookieUtils().save(some-key, some-value) throw new RestartResponseException(AnotherPage.class); The net result seems to be that Wicket uses an HTTP 3xx to get the user agent to go to the new page (which is what I want, since the URL changes), but the cookie does NOT get set. If instead of RestartResponseException the I use: RequestCycle.get().setResponsePage(AnotherPage.class); ...the cookie gets set properly and the redirect occurs as desired, but I need to perform the redirect in library code, which should prevent the calling thread from proceeding beyond the redirect point (which RestartResponseException nicely addresses). Is there some way to use RestartResponseException without discarding cookies?

Re: Cookies and RestartResponseException
So simple... I spent the last 8 minutes (i.e. till I received your reply) playing with a custom PageProvider, trying to set the cookie in getPageInstance(), (only to find that it doesn't matter since the 3xx redirect ends up retrieving the page from the default page provider anyway).
