Hi,
i would like to decouple the page dependencies. My page flow is
implemented by using bookmarkable page links.
As we all know they take a page class as parameter. This couples both pages.
So i thought it's a good idea to give the page class a name in my Spring
application context and reference it in
the caller page.
public StartPage extends WebPage {
@SpringBean(name="nextPageClass")
private Class<? extends Page> _nextPageClass;
public StartPage() {
add(new BookmarkablePageLink("toNextPage", _nextPageClass);
}
}
My application context defines:
<bean id="nextPageClass" class="java.lang.Class" factory-method="forName">
<constructor-arg value="my.NextPage"/>
</bean>
But it's not working while java.lang.Class is final. I get
Caused by: java.lang.IllegalArgumentException: Cannot subclass final
class class java.lang.Class

Can i do this in another way?
Thanks
