enclosure around listview
Hi,
Is there a way to hide a listview with an enclosure when there are no
items to display? One way to get it working is to toggle the visibility
of the listview based on wheter or not the list is empty or not. I was
expecting this would work out-of-the-box though...
Thanks,
Matthijs

Paste code of what you're looking to do. Your description seems like the
right way to do it. If you want that "out of the box", just roll your own
NotVisibleIfEmptyListView that overrides isVisible. Like:
public abstract class NotVisibleIfEmptyListView<T> extends ListView<T> {
private static final long serialVersionUID = 1L;
public NotVisibleIfEmptyListView(String id, IModel<List<T>> model) {
super(id, model);
}
@Override
public boolean isVisible() {
return CollectionUtils.isEmpty(getModelObject()) == false;
}
}
If you have other related markup (like you'll commonly have a <UL> tag, and
the list view is in your <LI> tag, just put a wicket enclosure around the
related markup (as you mentioned), and make it depend on the visibility of
the list view.

I think that's the normal way, in that you'd typically have both the list
and a "No items found" label, then set one or the other as visible...
