in this,i am referring two pages ,first one is to search for the products and add it to shopping cart in other page,now in other page i need some funtionality:
1.on delete , that item would be removed from cart and should display remaining items.
2.on edit, Quantity field should be converted to input field
3.on change of quantiy, amount should be updated.
i was able to implement delete,nut i m not able to implement 2 and 3,can anyone please resolve this issue.
it would be better if anyone could modify the code.

i am unable to search product either by name or by product code,i tried a lot but i am unable to find tghe solution,can anyone please go through the code and say what i am doing wrong in the code.
Error:Could not resolve the entity from <apex:inputField> value binding '{!Product.Name}'. <apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable.
could any one please suggest some solution to this problem
