you can also factor out the javascript confirmation into a behavior and
reuse it across any links classes like
Link link=new Link("foo") { onclick(){..}}.add(new
LinkConfirmation("sure?"));
BookmarkablePageLink link=new BPL(...).add(new LinkConfirmation("sure?"));

public class LinkConfirmation extends AbstractBehavior {
private final IModel msg;
public LinkConfirmation(String msg) { this(new Model(msg)); }
public LinkConfirmation(IModel msg) { this.msg = msg; }
@Override
public void onComponentTag(Component component, ComponentTag tag) {
super.onComponentTag(component, tag);
String onclick = tag.getAttributes().getString("onclick");
IModel model = msg;
if (model instanceof IComponentAssignedModel) {
model = ((IComponentAssignedModel)
model).wrapOnAssignment(component);
}
onclick = "if (!confirm('" + model.getObject().toString() + "'))
return false; " + onclick;
tag.getAttributes().put("onclick", onclick);
model.detach();
msg.detach();
}
}

To help reduce some code, why not extend the BookmarkablePageLink class to
form your JavascriptConfirmLink and then no need to write the onclick().
also try
new JavascriptConfirmLink(id, cls, new PageParameters("method=method1"),
msg)
and the id will be used here:
<span wicket:id="listViewId">
<a wicket:id="theLinkId" href="anotherPage?method=method1">method1</a>
</span>
You can ignore the href, as wicket will insert it for u.
I'm trying to make a page with several similar links to another page:

like I'd like so I end up having to new a PageParameters for each link
