First, you need to understand there are two different forms technologies in PDF - AcroForms (the classic form technology) and XFA (the modern, XML-based, forms tech).
Second, let's define "static" and "dynamic" in this context of forms (since it means something else in other contexts). In this context it means that the document's layout is either fixed (static) or flowing (dynamic). So if you have a table where the number of rows varies based on user entry, that's dynamic. If there is a fixed number of rows, that's static. AcroForms are always static. XFA can be either. In addition, XFA forms do NOT support commenting while AcroForms do. So if you need commenting, then you will either need to flatten the form into a "plain PDF" (no form fields or data information) or convert it to an AcroForm. At this time, only LiveCycle supports either/both of those operations on XFA dynamic forms. That help?

Hello, according to this message http://sourceforge.net/mailarchive/message.php?msg_name=D23D6B9E57D654429A9AB6918CACEAA97CA33AFD8D%40NAMBX02.corp.adobe.com I want to understand the difference between the static and dynamic pdf forms. Is there any source to read this? I know functional difference which are here described http://help.adobe.com/en_US/livecycle/8.2/static_dynamic_diffs.pdf but I need more information. I want to flatten a dynamic pdf or to make it static because the user should add comments. The server(livecycle) fill the pdf with data but there a some dynamic tables in it, so that I don't know the size of the table at design time so I need dynamic pdf but when the user display it, the pdf is static the user can't edit it. The should only add comments. So I need a transformation to static pdf or flatten pdf. Has someone for this problem an advice? Regards, Christoph
