Comment 2 for bug 1232033

[Response from the support on the OPW]

It does not seems a bug, the total amount is not displayed according to particular currency, currently total comes as sum of all amount, It is the job of the Web-Client to display the total by making sum of the field where sum attribute is defined, so Web-Client doesn't have to concern with currency, it simply do the sum of all values, also your record in list view shows 2500$ if you Sale for 2500$ even though the price of USD dollar is 0.80000.
Sale and Purchase is always displayed in the amount whatever your sale or purchase, the currency conversion comes into picture when you are dealing with parties i.e. any accounting transactions, like when you create an invoice(Customer or Supplier) then you can explicitly defined your currency of transaction.
Hope this will clears the picture that amount is displayed in quantity of transaction, it is not converted until and unless it comes to accounting transactions like Payment.
If you are activating multi-currency then it doesn't mean that whatever amount you purchase it is converted to your company currency instead it is displayed as it is(which is desired behavior that value of amount should not be converted immediately in form view of Sale according to company currency) and hence Web-Client do the sum of amount listed.
