Rosalind Douglas updated PDFBOX-4617:
-------------------------------------
Description:
Hello, thank you for all of your efforts in building and maintaining PDFBox. We
use it extensively for parsing PDFs, programmatically setting values and
flattening PDFs for print.
BUG: When we parse the attached PDF, the onvalues for the radio buttons are 0,
1, 2, 3, 4, which are determined by PDButton.getOnValueForWidget. Later on,
when we try to programmatically set the value of the radio buttons
(PDField.setValue) using the above onvalues, we receive this error:
{code:java}
java.lang.IllegalArgumentException: value '4' is not a valid option for the
field RadiosDuplicateExportValues, valid values are: [0, Choice2] and Off
at
org.apache.pdfbox.pdmodel.interactive.form.PDButton.checkValue(PDButton.java:376)
~[pdfbox-2.0.16.jar:2.0.16]
at
org.apache.pdfbox.pdmodel.interactive.form.PDButton.setValue(PDButton.java:158)
~[pdfbox-2.0.16.jar:2.0.16]
{code}
The radio buttons all have the same name, with either "Choice2" or "0" as the
choice value. We would expect it to behave like Adobe DC, which allows the user
to select any of the buttons regardless of whether they have the same choice or
not. I am on PDFBox 2.0.16.
Though my example might seem trivial, it's very easy for our PDF creating users
to do this because copying and pasting fields is the easiest way to build a PDF.
PROPOSED FIX:
This might be a regression caused by PDFBOX-3391. In our code, we have
overridden the PDButton.setValue method so that it always invokes
updateByValue(value) rather than sometimes using updateByOption(value). Here is
the code that works for us, from PDButton.setValue(String value):
{code:java}
@Override public void setValue(String value) throws IOException {
checkValue(value);
updateByValue(value);
applyChange(); }
{code}
One caveat is that the change would probably break your PDFBOX-3391 fix, but
perhaps there's some way to have them live side by side. I don't know very much
about the other problem.
Thanks again,
Rosalind
