Hi,
I've used PDFBox (2.0.7) to develop an interactive PDF document.When
complete, the user uploads the PDF to an app server.
In the many hundreds that have been successfully filled-out and
uploaded, I have had three instances where a rogue character has
corrupted the AcroForm object causing the upload to fail.
In two cases the rogue character is in the structure of the AcroForm
object, such that I cannot read data from that line of the object.
The other time, the rogue character was appended into a data value of
the AcroForm object.Although I could read the data value, it was not
the value that I wrote out when creating the PDF file.
I have attached three screen-shots showing the rogue characters.
Has anyone else experienced the same issue?I've looked through the web
and not found anything similar.
I'm confident that the rogue characters were not there when the file
was created.It is though they are put there while the user interacts
with the PDF.The user may open and close the file multiple times
before upload.
CheersFrancis
