that iterator you added has no much sense, as it represents only an
item on the list, but not the list itself.
moreover you don't need modifying components, but updating their
models, as mentioned in mail before (may you study wicket models a bit
more... see https://cwiki.apache.org/WICKET/working-with-wicket-models.html)
may you apply OnChangeAjaxBehaviour on each checkbox, instead of
adding a CheckGroup.
here's the code before, modified to work as you need, deselecting
other checkboxes when current one is selected:
[2]
java:
public class CheckBoxListPage extends WebPage {
private Form inputForm;
public CheckBoxListPage()
{
final FeedbackPanel feedback = new FeedbackPanel("feedback");
add(feedback);
add(inputForm = new InputForm("inputForm"));
}
/** form for processing the input. */
private class InputForm extends Form
{
// holds NameWrapper elements
private List<NameWrapper> data;
public InputForm(String name)
{
super(name);
// add some dummy data
data = new ArrayList<NameWrapper>();
data.add(new NameWrapper("one"));
data.add(new NameWrapper("two"));
data.add(new NameWrapper("three"));
data.add(new NameWrapper("four"));
// add a nested list view; as the list is nested in the
form, the form will
// update all FormComponent childs automatically.
final ListView<NameWrapper> listView = new
ListView<NameWrapper>("list", data)
{
protected void
populateItem(ListItem<NameWrapper> item)
{
final NameWrapper wrapper =
(NameWrapper)item.getModelObject();
item.add(new Label("name",
wrapper.getName()));
final CheckBox checkBox = new
CheckBox("check", new
PropertyModel<Boolean>(wrapper, "selected"));
item.add(checkBox);
checkBox.add(new OnChangeAjaxBehavior()
{
@Override
protected void
onUpdate(AjaxRequestTarget target) {
if
(wrapper.getSelected()) {
for
(NameWrapper entity : data) {
if
(!entity.equals(wrapper)) {
entity.setSelected(Boolean.FALSE);
}
}
}
target.addComponent(inputForm);
}
});
}
};
listView.setReuseItems(true);
add(listView);
}
public void onSubmit()
{
info("data: " + data); // print current contents
}
}
