I have tried to import a form that an error message pops up stating it is an XFA form. What product to I need to edit this form? Is it posslble to edit with Adobe Form?
A few things about the FormsCentral "Import PDF" feature:
1) FormsCentral does not enable you to "edit" a PDF form. A PDF form (AcroForm) can be imported to collect and manage responses through FormsCentral, when you distribute the Submission enabled PDF from FormsCentral a "Submit" button is added and the responses are collected through FormsCentral for analsys. No changes can be made to that PDF in FormsCentral, it allows you to download a submit enabled version of that form that will submit responses to FormsCentral and creates a Response Table and Summary Report in FormsCentral to display the results data.
2) XFA forms are not supported by FormsCentral
Adobe LiveCycle Designer is used to create/edit XFA forms: http://www.adobe.com/products/livecycle/tools/designer.html
Here is a little information on XFA forms vs flat PDF files and Acroforms: http://blogs.adobe.com/an_tai/archives/172
