hi, Folks
I am using vaadin 7.1.0 with xpoft addon .
http://vaadin.xpoft.ru
Everything works well until I abstract some methods into an abstract class for serveral Views.
Hope someone can help me solve it.
My abstract class -
[code]
public abstract class AbstractView extends Panel implements View {
CssLayout root = new CssLayout();
CssLayout menu = new CssLayout();
CssLayout content = new CssLayout();
private Logger logger = Logger.getLogger("web");
private PortalUI portalUI;
private DiscoveryNavigator contentNavigator;
public void PostConstruct() {
// render the view ...
...
setContent(root);
logger.debug(">> build root successfully.");
}
.... other stuffs
}
[/code]
Sub Class
@Component
@Scope("prototype")
@VaadinView(DashboardView.NAME)
public class DashboardView extends AbstractView {
public static final String NAME = "dashboard";
private Logger logger = Logger.getLogger("web");
@PostConstruct
public void PostConstruct() {
super.PostConstruct();
}
@Override
public void enter(ViewChangeEvent event) {
}But it is not what I expect in the end.
When it navigates to DashboardView, I get a blank screen.
In the log, I find “>> build root successfully”. So, the super class is called to build the content.
But why it does not come into the browser afterward ?
