title: Hava pdf files attachments into salesforce rendered as page 2 of a visualforce page renderAs=PDF
body: <p>On an custom object I have attachment files associated with it. The files are pdf. I would like to generate visualforce page where the first page is the mailing address associated with the custom object, and the page 2 is the attachment file (which is a pdf). The visualforce page has the RenderAs='pdf' attribute. How can I do this? I am familiar with extensions and how to query the body of an attachment.</p>
