I am a Wicket newbie and am currently struggling with
CompoundPropertyModel. I have found a lot on the list about
CompoundPropertyModel but not regarding this specific issue. I am
building a shopping cart. I have placed the cart's form inside a panel
and the cart items (via DataView) are inside the form. ShoppingCart is a
model that I would like to use to represent the current state of the
entire cart. It contains a array of ShoppingCartItem 's. However, when
running this, cartItems never gets set on the ShoppingCart model. While
debugging, cartItems is a child of the panelForm, but never gets
populated on the ShoppingCart pojo via CompoundPropertyModel. The form
does persist and if I traverse the panelForm object I could figure out
how to get to the ShoppingCartItem's...but I'd rather not. J
What am I missing? Is there a better way to do this? See code attached
below.
Thanks!!
<code>
...
public CartPanel(String id) {
super(id);
Form panelForm = new Form("panelForm", new
CompoundPropertyModel(new ShoppingCart())) {
@Override
protected void onSubmit() {
// need to rewrite cookie on update
ShoppingCart cart = (ShoppingCart) getModelObject();
System.out.println(cart.getCartItems());// check if
cart items got populated
}
};
add(panelForm);
IDataProvider dataProvider = new ShoppingCartItemsProvider();
DataView dataView = new DataView("cartItems", dataProvider) {
@Override
protected void populateItem(final Item item) {
final ShoppingCartItem cartItem = (ShoppingCartItem)
item
.getModelObject();
item.add(new Label("itemName", cartItem.getName()));
item.add(new TextField("quantity", new
ShoppingCartItemModel(
new Model(cartItem),
ShoppingCartItemType.QUANTITY)));
}
};
// add general text labels and buttons to the cart
addFieldsAndButtons(panelForm);
panelForm.add(dataView);
}...
</code>
Thanks!!
