I found a video on Adobe TV on PaperForms Barcode, this might help you
or just provide me, a sample that you are working on, i will take a look at it and provide you the fix if possible.
In my view paper form barcode should not be placed on master page. Anyways how you are assigning value to paperform barcode ?
Are you making your form reader extended ? You can pass your pdf to me for solution. email@example.com
We have a barcode in Masterpage of the module.
When we select from combo box in barcode becomes invisible.
Note: After lots of testing we came to know that the function presence used with different fields give this problem,which have no relationship with barcode.At the initialization of the barcode the code is written for it to be visible in all pages.
