I have written one VF page,1 extensions on opportunity detail page with show products button.Once i click show products,it will show all products present in that current opportunity.List of products will be wrapper class.So on selecting particular opportunityline items it should be downloaded as pdf.No. of pdf downloaded depends on Product_Type__c field.If total 2 types of opportunity line items are selected then on click of save the records it will download 2 separate pdf for different product type.Currently i m getting error.I am not able to rendered as pdf for any opportunity lineitems.Please help.I have edited the code with now one extensions and 2 vf page.2nd page will d one to be rendered as pdf.I am not sure if i am correct.Please suggest.
