Hi everyone! Maybe someone know what I am doing wrong. I follow this

and this:

<http://www.roseindia.net/tutorials/wicket/tab-wicket.shtml>
and I try to add Tabs wicket but I can't (Home page worked well before
adding this 'Tabs Wicket' ) ". I have this error:
Unexpected RuntimeException
Last cause: Cannot modify component hierarchy after render phase has started
(page version cant change then anymore)
Home.html:
<html>
<head>...</head>
<body>
HOME Page
<div wicket:id="tabs"> [tabbed panel will be here]
</div>
</body>
</html>
Home.java:
public class Home extends WebPage{
public Home() {
NavomaticBorder navomaticBorder = new
NavomaticBorder("navomaticBorder");
List tabs = new ArrayList();
tabs.add(new AbstractTab(new Model<String>("firstTab")) {
@Override
public Panel getPanel(String panelId) {
return new TabPanel1(panelId);
}
});
tabs.add(new AbstractTab(new Model<String>("secondTab")) {
@Override
public Panel getPanel(String panelId) {
return new TabPanel2(panelId);
}
});
// navomaticBorder.add( new AjaxTabbedPanel("tabs", tabs) );
navomaticBorder.add( new TabbedPanel("tabs", tabs) );
add(navomaticBorder);
}
}
