Hello,
I have a problem with a datatable and session managed bean, there is
the code and the error log. It's a very trivial code.
i'm using myfaces 1.1.0 release.
Thanks.
GeneralMenuBean.java
=================
import java.util.ArrayList;
import java.util.List;
import javax.faces.component.UICommand;
import MenuLink;
public class GeneralMenuBean extends BaseBean{
private List menuLinks;
public GeneralMenuBean() {
menuLinks=new ArrayList();
menuLinks.add(new MenuLink(new Integer(1),"xxxx","xxxxx"));
menuLinks.add(new MenuLink(new Integer(2),"xxxx","xxxxx"));
menuLinks.add(new MenuLink(new Integer(3),"xxxx","xxxxx"));
menuLinks.add(new MenuLink(new Integer(4),"xxxx","xxxxx"));
}
public List getMenuLinks() {
return menuLinks;
}
public void setMenuLinks(List menuLinks) {
this.menuLinks = menuLinks;
}
}
