If memory serves, the ListView will not repopulate already existing items. I
see two options:
1) setReuseItems(false)
2) instead of creating the label with a fixed String (I assume that
kmd.getName() returns a String) pass an IModel to the label like so:
New Label("kmname", new AbstractReadOnlyModel() {
public Object getObject() {
KeyMemberData kmd = (KeyMemberData)item.getModelObject();
return kmd.getName();
}
});
