java.lang.ClassCastException in ListMultipleChoice
Hi guys, I have a simple question. I´m using a ListMultipleChoice in my form. The selected items should be binded to Car.color as ListCar cars. If I bind the ListMultipleChoice to cars, I´ll get a java.lang.ClassCastException because wicket trys to map a ListString to ListCar. java.lang.ClassCastException: java.lang.String cannot be cast to com.***.***.Car Any ideas??? Thanks for your help

Betreff: AW: java.lang.ClassCastException in ListMultipleChoice
Hi, here my example:
### CarSearchPanel ###
// create formular
Form form = new Form(form);
BoundCompoundPropertyModel model = new BoundCompoundPropertyModel(new
CarSearchModel());
form.setModel(model);
...
// add cars
ChoiceRenderer carRenderer = new ChoiceRenderer();
carRenderer..put(1, Mercedes);// key, value
carRenderer.put(2, BMW);
carRenderer.put(3, Porsche);
ListMultipleChoice listMultipleChoice = new ListMultipleChoice(cars,
new Model(), renderer.getKeys(), renderer);// multiple selections possible
form.add(model.bind(listMultipleChoice, cars));
...
### CarSearchModel ###
private ListCar cars;
public ListCar getCars() {
return cars;
}
public void setCars(ListCar cars) {
this.cars = cars;
}
In SearchDao class, I iterate through a List of Car objects.

AW: integration Spring/Wicket/Hibernate problem with injection bean
Thanks for ur quick response.
I already read this article. But I don´t like this approach calling this
creation Proxy stuff when I need it for
from a Wicket-Bean.
private ContactDao dao = LazyInitProxyFactory.createProxy(ContractDao.class,
new IProxyTargetLocator() {
public Object locateProxyTarget() {
return
((MyApplication)Application.get()).getSpringContext().getBean(contactDao);
}
}
}
I´m knew to it and I´m struggeling for the right solution.
Is there no possibility to tell spring or wicket to do that in the background.
I´m just don´t want to care about it... is it now a dao bean or simple bean or
this special kind of wicket bean which I have to instantiate in another way.
What I want is simple to set this stuff in the applicationContext file.
And that spring does the injection throug the setter-method.
Thanks in advance for ur comments.
I apprciate it very much.
Cheers Phil

AW: Wicket and Mootools?
O, thank u very much for ur comments. I have some questions to you: 1. What is the package mini under contribution package for? What is the difference to package contribution/wicket-mootools??? 2. I also noticed that wicket offers you scriptaculous and jquery. Is there any comparsion between that frameworks? I´ve seen that scriptaculous is much more easier to understand and difinitely to use.

AjaxRequestTarget is null in Internet Explorer 6
Hi all
I´m struggeling with the AjaxFallbackLink the target object is null, if it runs
to the onClick() method.
In Firefox and Opera it works fine!!!
class MyPanel extends Panel {
private AjaxFallbackLink link;
public MyPanel() {
this.link = AjaxFallbackLink(link);
add(link);
}
public void onClick(AjaxRequestTarget target) {
if (target == null) {
System.out.println(my target is: + target); //target is null
} else {
System.out.println(my target is: + target);
target.appendJavascript(alert('is working'););
}
}
...
}
class MyPage extends WebPage {
private MyPanel myPanel;
public MyPage() {
this.myPanel = new MyPanel(myPanel);
add(myPanel);
}
}
If I add the AjaxFallbackLink to a WebPage instead to a Panel it works pretty
fine.
What I do is:
- call the page and click the link
- refresh the page through F5
- once again click the link

AW: SessionHandling: WicketRuntimeException: There is no application attached to current thread http-8080-1
Hello guys
The only thing what I was trying to do was, to execute some code
if a time out occurs. (mark that user is not anymore available or online).
How then can I achieve this behaviour?
Am I forced to use the classic instantiation through the new operator?
Or is there any other solution?

wouldnt say its a bug, looks like a method invocation is done on a
wicket-spring proxy outside a wicket request and it cannot find the
application when it tries to resolve the application context. those
proxies are not mean to be used outside wicket requests.

Hello Igor,
I just right now came back to my point.
Followed your hint and thinking once about it. You´re right, it works with
vanilla spring :-)
Thank you very much for your great help!!!

you can retrieve the application context via the servlet context and
use vanilla spring to do whatever it is you are trying to do. you only
need the proxies when dealing from inside wicket - which you do not
appear to be doing.
