Thank you very much!
Now that I know what to look out for, I think I must have been blind
while searching for an answer.
But my first reference, this cwiki page, missed out on this:
http://cwiki.apache.org/WICKET/listview-with-checkboxes.html
I just updated it and added the necessary line!
Best Regards,
Alex

ListView documentation states that you should "setReuseItems(true)"

Hi,
I am encountering a strange problem when adding DropDownChoices to a
ListView. Displaying and retrieving values works fine, BUT the
values are
lost during errorous form submission.
The following ListView is added to a form. When the form is submitted
successful all ModelObjects are updated fine.
But when submission fails ( e.g. because of some other fields which
are
required and values are missing) the DropdownChoices loose their
selected
values and return to the "original" ModelObject value.
Here is the code of the ListView:
public class TaskList extends ListView<ReminderTaskProxyModel> {
public TaskList (String id) {
super(id);
setRenderBodyOnly(true);
}
protected void populateItem (final
ListItem<ReminderTaskProxyModel>
listItem) {
ReminderTaskProxyModel model = listItem.getModelObject();
WeekdayChoice dayChoice = new WeekdayChoice("day");
dayChoice.setModel(new PropertyModel<Integer>(model, "day"));
listItem.add(dayChoice);
HourChoice hourChoice = new HourChoice("hour");
hourChoice.setModel(new PropertyModel<Integer>(model,
"hour"));
listItem.add(hourChoice);
listItem.setRenderBodyOnly(true);
}
}
WeekdayChoice and HourChoice basically extend DropDownChoice and
set the
choices and a renderer:
public class HourChoice extends DropDownChoice<Integer> {
public HourChoice (String id) {
super(id);
setChoiceRenderer(new HourRenderer());
List<Integer> hours = new LinkedList<Integer>();
for(int i = 1; i <= 24; i++) {
hours.add(i);
}
setChoices(hours);
}
private class HourRenderer implements IChoiceRenderer<Integer> {
private NumberFormat format = new DecimalFormat("00.##");
public Object getDisplayValue (Integer hour) {
return format.format(hour) + ":00";
}
public String getIdValue (Integer hour, int index) {
return String.valueOf(hour);
}
}
}
Any ideas, or hints where I might go wrong are greatly appreciated.
Thank you in advance!
Regards,
Alex
