why don't:
public class ArticleManager extends WebPage {
public ArticleManager(String id){
AjaxLink editButton = new AjaxLink("editButton") {
@Override
public void onClick(AjaxRequestTarget target) {
if(!AuthorizationManager.authorize(AuthorizationManager.WRITE,article)){
> setResponsePage(new
> UserAccessViolationPage());
> }
> else{
> setResponsePage(new
> Editor(article,panelIndex));
> }
}
};
