I think, there is a mutual mapping between html and java.
<ul wicket:id = "menu"> -- MenuView view = new MenuView("menu", menu);
add(view); // in HeaderPanel.java
-- item.add(new BookmarkablePageLink("link", clas, new PageParameters("id="
+ element.getId()))); // in MenuView.java
-- item.add(new Label("label", element.getLabel())); // in MenuView.java
Sorry, I see that I pasted the result code not the wicket templates. Here
are the real template files:
HeaderPanel.html
<html xmlns:wicket>
<body>
<wicket:panel>
<h1>Wicket Example</h1>
<p id="titleblock">
Start of Example Title Goes Here
</p>
<ul wicket:id = "menu">
<li> </li>
</ul>
</wicket:panel>
</body>
</html>
HomePage.html
<html>
<head>
<title></title>
<link wicket:id='stylesheet'/>
</head>
<body>
Hello
</body>
</html>
