Hello to all,
i am trying to build a dynamic menu based on data from a database. So i
thought i could build it like my code shows it. To highlight the
selected menu i try to dynamically add an attribute to the li tag in the
onClick method. I would also want to load and repaint other panels (for
example loading sub menus ), when the user clicks a menu link. But it is
not working. What am i doing wrong?
<pre>
ListView<Menu> lv = new ListView<Menu>("mainMenu", menuList) {
@Override
protected void populateItem(final ListItem<Menu> item) {
Menu menuItem = (Menu) item.getModelObject();
Link<Menu> link = new Link<Menu>("menuLink") {
@Override
public void onClick() {
item.add(new AttributeAppender("id", new
Model("current_menu"), ";"));
System.out.println("item was clicked " +
item.getPath());
}
};
link.add(new Label("menuCaption",
menuItem.getMenuNameDe()));
item.add(link);
}
};
add(lv);
</pre>
and this is my panel markup:
<pre>
<body>
<wicket:panel>
<ul>
<li wicket:id="mainMenu">
<a href="#" wicket:id="menuLink"><span wicket:id="menuCaption"></span></a>
</li>
</ul>
</wicket:panel>
</body>
</pre>
My goal:
<pre>
<body>
<wicket:panel>
<ul>
<li wicket:id="mainMenu" id="current_menu">
<a href="#" wicket:id="menuLink"><span wicket:id="menuCaption"></span></a>
</li>
</ul>
</wicket:panel>
</body>
</pre>
Thank you for any help!
