Writing Adobe PDF plugin and accessing fields created in Adobe LiveCycle Designer ES 8.1

I am having issue reading Form Fields in a PDF Generated using Adobe LiveCycle Designer ES 8.1 . The AFPDDocEnumPDFields does not produce results in the callback. I was able to get a list of fields using Javascript getNthFieldName. Once I got the field setting a the rawValue does not update the field.

Can anyone help with this
