Matej, ListView is a component conceptually equal to Label, TextField or
whatever. The code I sent doesn't work. And yes I'm adding it to a
target, the same way I do for a Label which works fine without adding it
to a parent component.
ListView is an repeater. It works differently than label or TextField.
Btw. if you hide the label like this (you'll add the label to the target
directly), you won't be able to show it untill you refresh the page. So
you have to put it in a webmarkupcontainer anyway. (Wicket uses
outerHtml to replace the component and if you want to show hidden label
document.getElementById('labelId') will just return 'undefined').

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.
