Thanks!
I was just wondering how to cache it as the performance immediately took
quite a bad hit when I used ListView, RepeatingView is much much better
for my nav purposes.

I'd rather use RepeatingView, together with a utility method for
adding the menu items. A ListView refreshes the menu on each render,
and your menu is rather static.
something like:
RepeatingView rv = new RepeatingView("menu");
addMenuItem(rv, "Name of menuitem", PageThatIsLinkedTo.class);
private void addMenuItem(RepeatingView rv, String labelText, Class<?
extends WebPage> page) {
BookmarkablePageLink link = new BookmarkablePageLink(rv.newChildId(), page);
link.add(new Label("label", labelText));
rv.add(link);
}

Thanks Martijn,
I think I stumbled on the solution just before I saw your hint =).
Please help me take a look and see if the way I approached the problem is
too cumbersome.
Basically my HTML, in my NavigationalPanel.html:
<span wicket:id="links">
<a href=# wicket:id="link"><span
wicket:id="displayName"></span></a><br/>
</span>
Java, I have a NavigationPanel:
public class NavigationPanel extends Panel {
public NavigationPanel(String id) {
super(id);
List<CustomLinkedPage> links = new
ArrayList<CustomLinkedPage>();
links.add(new CustomLinkedPage("Home Page", HomePage.class));
links.add(new CustomLinkedPage("Some Page", SomePage.class));
add(new ListView("links", links) {
public void populateItem(final ListItem item) {
final CustomLinkedPage link = (CustomLinkedPage)
item.getModelObject();
item.add(new CustomBookmarkablePageLink("link",
link.getPageClass(), link.getDisplayName()));
}
});
}
class CustomLinkedPage {
Class pageClass;
String displayName;
public CustomLinkedPage(String displayName, Class pageClass) {
this.pageClass = pageClass;
this.displayName = displayName;
}
// remved getters and setters for less verbosity }
class CustomBookmarkablePageLink extends BookmarkablePageLink {
public CustomBookmarkablePageLink(String id, Class pageClass, String
displayName) {
super(id, pageClass);
this.displayName = displayName;
add(new Label("displayName", displayName));
}
String displayName;
// remved getters and setters for less verbosity }
}
I tried subclassing BookmarkablePageLink directly without CustomLinkedPage
but it created "inelegant" code that made me put "link" at new instance time
which I hated, because the "link" reference seems to be in the wrong scope.
Spent lots of time researching and had a hard time figuring this out. The
amount and quality of documents in Wicket is not rich enough for newbies to
get up to speed quickly enough. Having said that, I totally love the
component object model. No other framework (I worked with quite a number of
them) lets me subclass so nicely and having such neat code in html! =)

Use normal BookmarkablePageLinks instead of <wicket:link>. The latter
is just convenience and only supports the most basic stuff.

Hi,
I think I'm the minority here but I like how wicket's default behaviour
of
placing html with the page.
I have a problem that I hope someone has encountered and solved before.
Basically, I current my source structure to be as follows
com/acme/web/HomePage.java
com/acme/web/HomePage.html
com/acme/web/SomePage.java
com/acme/web/SomePage.html
com/acme/panel/NavPanel.java
com/acme/panel/NavPanel.html
In my NavPanel.html, I have some links to HomePage.html as well as
NavPanel.html. <a href="SomePage.html">Some Page</a>
This works. The debug shows that Wicket is automatically figuring which
page
to link to link to.
But when I do the following
com/acme/proga/SomePage.java
com/acme/proga/SomePage.html
com/acme/home/HomePage.java
com/acme/home/HomePage.html
com/acme/panel/NavPanel.java
com/acme/panel/NavPanel.html
Wicket debug warning shows that it is unable to figure what Page class to
give <a href="SomePage.html">Some Page</a>.
WARN org.apache.wicket.markup.resolver.AutoLinkResolver - Did not find
corresponding java class: com.acme.home.SomePage
I am thinking that probably what I'm trying to do is wrong. If so, what
is
the proper way to make the pages available in a Navigator?
I tried building the links dynamically by iterating a list of pages and
getting the paths from there BUT I am stuck trying get a list of Pages of
my
application.
Is there a way for me to resolve this?
Thanks in advance.
