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...

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... I was expecting this would work out-of-the-box though...

Re: enclosure around listview
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 NotVisibleIfEmptyListViewT extends ListViewT {
private static final long serialVersionUID = 1L;
public NotVisibleIfEmptyListView(String id, IModelListT 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.
