> Key: PDFBOX-4617
> URL: https://issues.apache.org/jira/browse/PDFBOX-4617
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Reporter: Rosalind Douglas
> Priority: Major
> Attachments: Radio buttons with duplicate names and choices.pdf
>

> 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. Then, when we try to programmatically set the value of the radio buttons (PDField.setValue) using the above options, we receive this error:
> {code:java}
> 2019-07-31 08:59:36 ERROR (Prism.java:3744)- STACK: java.lang.IllegalArgumentException: value '1' is not a valid option for the field radio1, valid values are: [no, yes] 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, and two of them have the same 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.
> 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
