Re: CheckGroup and back Button problem
If I instead of item.getModel() for the Check, uses some PropertyModel that
evaluates to a String identifier it works fine, but then only the identifier
is saved, and not the object, which as I understand it should be the
purpose. I haven't looked at the code, but I wander what uuid is exactly as
the equals apparently fail on non basic types. Will have a look when I get
the time. Thanks for the hint.

Re: CheckGroup and back Button problem
We seem to have a similar problem with a wizard page. We came across the
following code in Check.onComponentTag(..)
if (group.hasRawInput())
{
final String[] input = group.getInputAsArray();
if (input != null)
{
for (int i = 0; i < input.length; i++)
{
if (uuid.equals(input[i]))
{
tag.put("checked", "checked");
It looks like the Check component is checking for the existence of raw
input, but then using the input from the current request (via
getInputAsArray()) to render. Sounds fishy! I figure this could be related?

CheckGroup and back Button problem
Hi,
I have made a CheckGroup vith a ListView of Check's than works fine, except
that when it is submitted and I'm on the next page and want to go back
through a Wicket Button (not the browsers back button), all the checks are
empty even thouch the model behind still contains the selected obejcts. Here
is the example code of the first page:
public HomePage() {
Order order = ((WicketSession) (Session.get())).getOrder();
if (order.getDigitalPackets() == null)
order.setDigitalPackets(new ArrayList());
System.err.println("LIST1 = " + order.getDigitalPackets());
Form form = new DigitalOrderForm("digitalOrderForm");
form.setModel(new CompoundPropertyModel(order));
add(form);
List allProducts = new ArrayList();
for (int i = 0; i < 10; i++) {
Product p = new Product();
p.setProductKey(i + "");
p.setTotalPrice(new BigDecimal(100 + i));
p.setProductName("Product" + i);
allProducts.add(p);
}
CheckGroup group = new CheckGroup("digitalPackets");
form.add(group);
ListView products = new ListView("products", allProducts) {
protected void populateItem(ListItem item) {
item.add(new Check("check",
item.getModel()).setEscapeModelStrings(false));
item.add(new Label("productName", new
PropertyModel(item.getModel(), "productName")));
item.add(new Label("totalPrice", new
PropertyModel(item.getModel(), "totalPrice")));
}
};
group.add(products.setReuseItems(true));
}
class DigitalOrderForm extends Form {
DigitalOrderForm(String s) {
super(s);
}
protected void onSubmit() {
Order order = (Order) getModelObject();
System.err.println("LIST2 = " +
order.getDigitalPackets());
setResponsePage(PageTwo.class);
}
}
The second page is just a back button like this:
public PageTwo() {
add(new Button("back") {
public void onSubmit() {
setResponsePage(HomePage.class);
}
});
}
Anybody knows how to get the selected objects shown when you go back like
that ?
