I have designed a form that contains a PDF417 barcode using the Paper Forms Barcode object. I have both limited then number of fields that are included and limited the amount of data that goes into the barcode. After "Extending Features in Acrobat Reader" and opening the form in Reader 9.3.4 when ever I change the data on one of the fields in the barcode collection the barcode blanks and becomes a gray box. The same form works correctly with Acrobat Pro 9.3.1.
What do I need to do to have the barcode field work in Acrobat Reader?
