One thing at a time:
1) setVisible works, when not doing through Ajax components like AjaxLink;
2) ListView outputs one different id for each repeated line.
3) when calling ListView.setVisible(false) from some
onClick(AjaxRequestTarget), it does not works.
So pay attention to 3': setVisible can be called from anywhere that
ListView does not have to know about. And this problem I'm talking
about, it's been called from an Ajax component. This let me conclude
that this code should work:
...
final ListView listView = new ListView("list", items) { ... };
listView.setOutputMarkupId(true);
add(listView);
final Label label = new Label("foo", new Model("Foo"));
AjaxFallbackLink link = new AjaxFallbackLink("ajaxLink") {
public void onClick(AjaxRequestTarget target) {
listView.setVisible(false);
label.setVisible (false);
target.addComponent(label); // this one works
target.addComponent(list); // this does NOT works
}
};
add(link);
...
The way setVisible(false) is been called should not be important on how
the component must behave. If it should, so in the javadoc would be
needed to have some comment warning the user about that. " Do not call
setVisible(false) from Ajax components."
But why? Of course setVisible works on listview, why wouldn't it? The
problem is that you are adding the list view to target. You should add a
component that contains the listview.

That's what I think.
