How to restrict the total order size to 10 in atg CRS store

Question

Hi,
i want to restrict customer from selecting orders not more than 10 either the same product or different one. i got the solution for same product but the problem is when i am trying to restrict the customer from selecting items more than 10 by changing some code in StoreCartFormHandler.java . i cant able to get that....... and i'll also explain what are all the changes which i have made in that like putting condition for overallQuantity attribute it was not effecting the code. can anybody please tell me what else i've to do...

Answer 1

Thanks for the reply,
Mr.Rsharma and karthik you both said that orderHolder oh=getcurrent(); but that getcurrent() method was not there in that. when i am trying to write that it was showing getCurrentTransaction(). and also i want to know from you guys that i need to make changes to preaddItemsToOrder() or addItemsToOrder(). i am editing the preaddItemsToOrder() And as i am new to ATG i dont clearly know what are all the methods like OrderHolder or commerceItems.and i want to restrict the user from selecting items of same type or different type that overallitems should not exceed 10.
i am pasting my code over here.which i have written from your references.
OrderHolder shoppingCart = (OrderHolder) this.resolveName(SHOPPING_CART, false);
     Order order = shoppingCart.getCurrent();
     List info=order.getCommerceItems();
     if(info!=null)
     for(Object ob:info){
               Nquantity +=getQuantity(((CommerceItem)ob).getId(), pRequest, pResponse);
     System.out.println("the new quantity is"+Nquantity);
sorry if i am not clear.
