Why not make a new panel component that has a ListView and a label at

I need this component in many places, every time with different markup
for
between <li> and </li>. Therefore I am interested in solutions that
allow
the user of the component to provide the markup (as users of ListView
can
do right now).

I try to code a subclass of ListView that adds some markup after

public abstract class NodeListView extends ListView<Node>
{
public NodeListView(String id, IModel<List<SessionNode>> model,
boolean
showFooter)
{
// ...
}
// ...
}
Ideally, I'd like users of this class to provide the markup, for
instance:
<ul>
<li wicket:id="list"><wicket:container wicket:id="node"/></li>
</ul>
with code
add(new NodeListView("list", listModel, true)
{
@Override
protected void populateItem(ListItem<SessionNode> item)
{
item.add(new Label("node, /* ... */));
}
});
With this approach, is it possible to add markup from within
NodeListView?
Could a behaviour help (or overriding onRender() if it were not
final)?
Another option would be to make NodeListView a Panel with
associated markup
and have clients of NodeListView pass in a fragment, which is a bit
unreadable:
<wicket:container wicket:id="list" />
<wicket:fragment wicket:id="list-item">
<wicket:container wicket:id="node"/>
</wicket:fragment>
with
add(new NodeListView("list", listModel, true,
new Fragment(NodeListView.ITEM_ID, "list-item", this)));
Any ideas?
Thanks, Kaspar
