Re: CheckboxMultipleChoice in Ajax style
Mathias, I changed a bit of code and now it works without problems. I even can't reproduce what was the problem. Thank's a lot for your help Philipp When I try this code it works.

Re: CheckboxMultipleChoice in Ajax style
Hi Mathias, hi all,
thanks for your help, I didn't know the
AjaxFormChoiceComponentUpdatingBehavior so far.
I now have the problem, that it jumps into the onUpdate method just once
(when I click on a checkbox for the first time). If I click again on the
same or any other checkbox, nothing happens. Does anyone have an
explanation for that?
Thank you
Philipp
This may confuse the web user quite a bit. It's preferred to send the request
each time or cache it maybe.
Form form = new Form( form );
List SITES = Arrays.asList(new String[] { The Server Side, Java
Lobby,
Java.Net });
final ListString values = new LinkedListString();
final CheckBoxMultipleChoice c = new
CheckBoxMultipleChoice(site, new
Model(), SITES );
c.add( new AjaxFormChoiceComponentUpdatingBehavior(){
@Override
protected void onUpdate(AjaxRequestTarget target) {
System.out.println( c.getModelObject() );
}
});
form.add( c );
add( form );
In this onUpdate you could send to server, cache or whatever.

CheckboxMultipleChoice in Ajax style
Hi all, I wonder how I can create a CheckboxMultipleChoice that performs an action onUpdate. Ideally, the action is delayed by one second, so that a user has the chance to change more than one checkbox before the change is sent to the server (without a submit button). As I'm quite new to wicket, any code fragment would be greatly appreciated.

Re: Servlet container authentication in Wicket
Hi,
I had a look at that specification but it doesn't give any more hints
how to use it. Does somebody have any more working examples? Or is there
a tutorial how to connect wicket to the local LDAP?
Thanks for your help.

j_security_check is part of the Servlet Specification section
SRV.12.5.3.1 Login Form Notes (at least for version 2.5). It did
exist in earlier versions but I've only quoted the latest.

Re: Servlet container authentication in Wicket
Hi all,
just as a last reminder (before the article is archived;-), is there
anybody who yould provide me with an example how to user Servlect
container authentication in Wicket? I followed the example in
http://cwiki.apache.org/WICKET/servlet-container-authentication.html but
I get the error mentioned below. Maybe some more configuration in tomcat?
Thank you for your help

Hi Timm,
I also tried to add my application name in it (like you proposed), but
no difference, still doesn't work.

Shouldn't there be an application named?

Budy indicator next to a checkbox

ajaxcheckbox does not have a method public String
getAjaxIndicatorMarkupId() so what are you trying to override? instead
let your panel implement see IAjaxIndicatorAware

Re: UTF-8 bug in wicket? Or in Tomcat?
Hi Jonas,
thanks for your help, but I think it doesn't help. Just to make sure
that I understood the Application#init correctly, you meant to do it
like this, right(?):
public class MyApp extends WebApplication {
public void init()
{
getRequestCycleSettings().setResponseRequestEncoding(UTF-8);
getMarkupSettings().setDefaultMarkupEncoding(UTF-8);
}
public Class getHomePage() {
return Index.class;
}
}
Still, it seems to convert my code from latin1 to utf8, even though I
enter utf8-text.
Thanks for further help
Philipp
Hi,
have you tried setting
getRequestCycleSettings().setResponseRequestEncoding(UTF-8);
getMarkupSettings().setDefaultMarkupEncoding(UTF-8);
in your Application#init
If you don't set the default markup encoding explicitly, the default
for it is the 'os provided encoding' (see:
IMarkupSettings#getDefaultMarkupEncoding)
cheers,
Jonas

Re: UTF-8 bug in wicket? Or in Tomcat?
Hi Jonas, hi Johann,
grrh, I forgot to set URIEncoding=UTF-8. Now it works, thank you for
your help.
All the best
Philipp
Hi Philipp,
yes, thats correct. We had similar problems and fixed it that way, but maybe
something else is still not set to UTF-8.
I assume you have configured your tomcat connector using
URIEncoding=UTF-8 (I think that is what Johan is referring to?).
Have you tried adding a meta tag to your markup? Something like
[meta http-equiv=Content-Type content=text/html; charset=UTF-8 /]
cheers,

Re: Focus on component
Hi Matthew,
this solution works perfectly well, thanks a lot.
Philipp
You can write a behaviour for it so it will be more reusable.
The following is based on
http://cwiki.apache.org/WICKET/request-focus-on-a-specific-form-component.html
and
works for both regular and ajax requests.
private final class MyLink extends AjaxFallbackLink
{
public void onClick(AjaxRequestTarget target)
{
onShowForm(target);
myField.add(new FocusBehavior());
}
}
public class FocusBehavior extends AbstractBehavior
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void bind(Component component) {
super.bind(component);
component.setOutputMarkupId(true);
final Response response = component.getResponse();
if (response instanceof WebResponse !((WebResponse)response).isAjax()) {
component.setComponentBorder(new IComponentBorder() {
/**
*
*/
private static final long serialVersionUID = 1L;
public void renderBefore(Component component) {
}
public void renderAfter(Component component) {
final Response response = component.getResponse();
response.write(
script type=\text/javascript\
language=\javascript\document.getElementById(\ +
component.getMarkupId() +
\).focus()/script);
}
});
}
this.component = component;
}
private Component component;
@Override
public void renderHead(IHeaderResponse response) {
if (response.getResponse() instanceof WebResponse
((WebResponse)response.getResponse()).isAjax()) {
response.renderOnLoadJavascript(document.getElementById(' +
component.getMarkupId() + ').focus());
}
}
@Override
public boolean isTemporary() {
return true;
}
}

use target.(pre|append)Javascript if you want additional JS executed
before/after doing the wicket-ajax stuff
if you only want to set the focus (without any ajax involved), don't use
ajaxlink, use e.g. a simple WebmarkupContainer

UTF-8 bug in wicket? Or in Tomcat?
Hi all, when I enter German umlauts (e.g. äöü) in a wicket text field it's converted to äöü. Everything seems to be in UTF-8. I already tried to apply a filter as described in http://wiki.apache.org/tomcat/Tomcat/UTF-8 without success. Any ideas?

Re: UTF-8 bug in wicket? Or in Tomcat?
Hi Mathias, 'äöü' is actually already converted to 'äöü' when I add a breakpoint at the onSubmit method of my form (so right when I get the input of the text field from my model). My whole eclipse is in UTF-8, Wicket writes UTF-8 to each HTML-Page, my firefox says UTF-8. What I think is that Wicket or Tomcat treats my UTF8-String äöü as an ISO-8859-1 String and converts it from iso to utf8, so into 'äöü'. When I copy 'äöü' into a tmp.txt file in unix-shell which is in UTF-8 and do an iconv -futf8 -tlatin1 tmp.txt on it, the output is 'äöü' again. Any idea what to do? All the best Philipp Do you save it to a database and then display the text? How do you present it? -- Averbis GmbH c/o Klinikum der Albert-Ludwigs-Universität Stefan-Meier-Strasse 26 D-79104 Freiburg Fon: +49 (0) 761 - 203 6707 Fax: +49 (0) 761 - 203 6800 E-Mail: dau...@averbis.de Geschäftsführer: Dr. med.

Render other components

I look for an example how to render Wicket-Components (in my case an
AjaxDefaultDataTable) triggered by other Components (in my case

Java-Classes. I looked for a while in the examples and in the wiki, but
coudln't find anything.

To make a silly example, I look for something like:

AjaxLink link = new AjaxLink(link, new PropertyModel(obj, id))
{

{
getComponent(myAjaxDefaultDataTable).render();
}
};
...
class2

{
{
setOutputMarkupId(true);

I'm not sure I have fully understood what you are after but it may be that
something as straight forward as making the component to be added (ADDT)
invisible - setVisible(false) - when first added to its parent (eg the page)

Don't forget to setOutputMarkupPlaceholderTag(true) as well as
setOutputMarkupId(true) on your ADDT and to add the ADDT to the

Re: Render other components
Hi Jonas, hi Cemal,
I think both of you mean similar things. So I need to attributes in my
custom panel, one for the referring instance (in my case an instance of
Class Index) and one for the component that I want to render (in my case
AjaxFallbackDefaultDataTable). So my new custom panel looks like the one
below. Agree?
Thank you for your help
Philipp
public class TermIDLinkPanel extends Panel
{
Index indexInstance;
Component componentInstance;
public TermIDLinkPanel(Index indexInstance, Component component,
String id, final IModel model, final Item item)
{
super(id, model);
this.indexInstance = indexInstance;
this.componentInstance = component;
...
AjaxLink link = new AjaxLink(link_termID, new
PropertyModel(obj, id))
{
public void onClick(AjaxRequestTarget target)
{
target.addComponent(componentInstance);
Page page = target.getPage();
//API to change the result list that shall be newly rendered
TermIDLinkPanel.this.indexInstance.updateRelationResultList();
target.addComponent(componentInstance);
}
};
add(link);
}
}
Philipp,
I expect your page's constructor creates and adds your custom panel. So,
either make the whole panel invisible, or, if the panel hosts other widgets
that need to be shown before your AjaxLink is clicked, you can provide an
API on your panel to make the ADDT invisble/visible. This would be better
than accessing the ADDT directly (encapsulation).
Is that what you meant? If not, create the simplest possible
http://wicket.apache.org/quickstart.html QuickStart (remember to delete the
target folder), zip it up and attach the zip file to your post so we can
take a look.
Regards- Cemal
http://www.jWeekend.co.uk jWeekend
Hi,
I somehow doubt this is considered good practice to let one component
know where in the component tree another component is situated.
The code you propose breaks very easily e.g. if you introduce another
container around the ADDT. Why don't you just pass the ADDT instance into
the AjaxLink?
something like:
final AjaxFallbackDefaultDataTable myADDT = ...
AjaxLink link = new AjaxLink(link, new PropertyModel(obj, id))
{
public void onClick(AjaxRequestTarget target)
{
target.addComponent(myADDT);
}
}
...but I'm not sure if that's a better practice. At least this doesn't
break as easily if you change the position of the ADDT in the component
tree.
Maybe a core-dev could shed some light on this issue?
cheers,
Jonas

I'm not sure I have fully understood what you are after but it may be
that
something as straight forward as making the component to be added (ADDT)
invisible - setVisible(false) - when first added to its parent (eg the
page)
and making it visible in your AjaxLink (AL) onClick implementation.
Don't forget to setOutputMarkupPlaceholderTag(true) as well as
setOutputMarkupId(true) on your ADDT and to add the ADDT to the
AjaxRequestTarget - target.addComponent(myADDT) - in that onClick method.

Dear all,
I look for an example how to render Wicket-Components (in my case an
AjaxDefaultDataTable) triggered by other Components (in my case AjaxLink).
In my case the two components are defined in different Java-Classes. I
looked for a while in the examples and in the wiki, but coudln't find
anything.
I appreciate your help or just a few links to some examples!
All the best
Philipp
To make a silly example, I look for something like:
class1
AjaxLink link = new AjaxLink(link, new PropertyModel(obj, id
How can FeedbackPanel show error message of AjaxEditablePanel ?
Hi all, I try to show the error message of an AjaxEditablePanel in a FeedbackPanel, but it doesn't work. On the web I only find examples where FormComponents are validated. My AjaxEditablePanel is not part of a form? Any idea or example?

DefaultDataTable and AjaxEditableLabel
Dear all,
I try to create an editable column using DefaultDataTable and
AjaxEditableLabel. My current version is posted below but it's quite a
hack and I wonder whether there's an official good solution for that
before I go on with my work.
Thanks al lot for your help

Re: DefaultDataTable and AjaxEditableLabel
Hi Uwe, thanks for the link. I agree that my model passing is weird. Your link to the example explains an editable TreeTable but I look for a DataTable example. In that tree table example I cannot use the tree.table.PropertyEditableColumn as as the DefaultDataTable I want to use requires data.table.IColumns (not tree.table.IColumns) , or am I wrong? Or can I just cast them? Another ideas? Not to be mentioned I'm a wicket newbie and there's maybe a very simple solution for that Thanks, Philipp Philipp Daumke schrieb: I try to create an editable column using DefaultDataTable and AjaxEditableLabel.
