public SoldItemForm(List<Item> allItems) {
        addClassName("item-form");

        // * item field 
        itemList.setItems(allItems);
        itemList.setItemLabelGenerator(Item::getItemName)
        itemList.addValueChangeListener(event->{
            if (event.getValue() != null){
                quantityStock.setValue(event.toString());
                
            }
        });
        

        // * Item Stock 
        quantityStock.setReadOnly(true);

        add(itemList, quantityStock);

    }

CodePudding user response：

Replace event.toString() with event.getValue().getItemName(). Currently you are printing the whole event instead of the event's value/item.
