Re: ClassCastException: wicket.in.action.CheesrSession cannot be cast to wicket.in.action.CheesrSession
I have also tried same examples without any issues. Try it on another server
instance or completely different server. There should be someting wrong in
your jetty, eclipse combination. This kind of classcastexceptions (can not
cast A to A) are a result of class loader hierarchy of app servers. Some how
same class is loaded by 2 different class loaders.

you either somehow have two of these on your classpath or tomcate
creates another one via a different classloader and then you have a
class from one classloader trying to cast to a class loaded from
another one...its probably an environment problem :/

Re: ClassCastException: wicket.in.action.CheesrSession cannot be cast to wicket.in.action.CheesrSession
Hi,
I know that 1.3 is not the latest version, but I think that's the
version used in the book. Since I am learning wicket I don't want to
deal with compatibility issues.
I tried the latest version (1.5.1) and the result is worse. If I
refresh the browser 3 times I get the same exception and this time I
didn't have to redeploy.
What strikes me is that the wicket can not cast
wicket.in.action.CheesrSession to wicket.in.action.CheesrSession
public class CheesrSession extends WebSession {
private Cart cart = new Cart();
public CheesrSession(Request request) {
super(request);
}
public Cart getCart() {
return cart;
}
}
ERROR o.a.w.Component> Error while getting default model object for
Component: [ [Component id = cart, page = wicket.in.action.Index, path

Hello, Your wicket version is fairly old. Please try the latest 1.5 release... Have a look at the wicket examples they provide a very good starting point.

ClassCastException: wicket.in.action.CheesrSession cannot be cast to wicket.in.action.CheesrSession
Hi, I'm doing my first experiments with wicket. I'm testing the example in chapter 3 (Wicket in Action) with eclipse and embedded jetty. The wicket version I'm using is 1.3.7. The example provided works quite well except when I make a change and redeploy it to jetty. Then I get an unexpected RuntimeException. The only way to get the changes working is with a server restart. Wicket is running in DEVELOPMENT mode.
