Apple

Little change...

Because some problem with refresh I moved the TemporaryOrder object from the component to the session.

This does not change the problem..

PS:

How radio button &C. work??

(I've seen WORadioButtonList is deprecated.. Should I use ERXRadioButtonMatrix?... but selection is not.. selected!)

Hi..
This is a very simple question, and I was able to find a workaround.. but I'd like to know where is the problem...

I've this class:

public class OrderComponent extends ERXComponent {

private TemporaryOrder order;

public OrderComponent(WOContext context) {
super(context);
}

public void setOrder(TemporaryOrder order) {
this.order = order;
}

public TemporaryOrder order() {
return order;
}

@Override
public void awake() {
super.awake();
setOrder(null);
}

}

All my order classes inherit from that class. (this only to have the order object without rewriting it every time..).

If I have this binding:

CartSubtotal: WOString {
value = order.cart.cartTotal;
numberformat = "$#0.00";
}
When I render the page I get this exception:

valueForKey(): lookup of unknown key: 'cartTotal'. This class does not have an instance variable of the name cartTotal or _cartTotal, nor a method of the name cartTotal, _cartTotal, getCartTotal, or _getCartTotal' object 'com.portonapoleone.store.utils.CartItem@eac903' key 'cartTotal'>

If I change the binding to this I have no problem:

CartSubtotal: WOString {
value = cartTotal;
numberformat = "$#0.00";
}

public double cartTotal() {
return order().cart().cartTotal();
}

These are the other classes involved:

public class TemporaryOrder {
private CartArray cart;
private String shippingAddress;

public TemporaryOrder(CartArray c) {
cart = c;
}

public CartArray cart() {
return cart;
}

public void setShipmentAddress(String shipmentAddress) {
this.shipmentAddress = shipmentAddress;
}

public String shipmentAddress() {
return shipmentAddress;
}

}

public class CartArray extends NSMutableArray<CartItem> {

public boolean add(Prodotto p) {
return add(p,1);
}

public boolean add(Prodotto p, int i) {
CartItem ci = new CartItem(p);
if (contains(ci)) {
CartItem oldCI = objectAtIndex(indexOf(ci));
oldCI.quantity += i;
return true;
}
else {
ci.quantity = i;
return super.add(ci);
}
}

public double cartTotal() {
double total = 0;
Iterator<CartItem> it = this.iterator();
CartItem ci = null;
while (it.hasNext()) {
ci = it.next();
total += ci.totalPrice();
}

return total;
}

}
