Another PDF with non-behaving form fields
This one is https://ulfdittmer.com/pdfbox/Guide_HE.pdf
<https://ulfdittmer.com/pdfbox/Guide_BW.pdf>
I can use PDFBox to fill in the fields on page 1, but not some of those on
page 2 - they're not changed. Specifically, "Wohnanschrift im Ausland:
Staat" and "Adresse" as well as "E-Mail-Adresse" and "Telefonnummer"
The PDFBox Debugger shows those form fields, but the PrintFields example
code (
https://github.com/apache/pdfbox/blob/trunk/examples/src/main/java/org/apache/pdfbox/examples/interactive/form/PrintFields.java)
does not. Those 4 that I mentioned are not in its output, and using the
field names from PDFDebugger does not work.
Am I missing something, or is there more going on?

Hello Ulf,
pdfbox does apply some fix ups automatically when doing .getAcroForm().
One is to check for widgets which doen't have a field entry as is the
case in your form and create them.
You can look up the code in AcroFormDefaultFixup.
The way it's currently done is that this only kicks in if there are no
fields at all, which is not the case in your form.
But you can create your own fix up and call
.getAcroForm(PDDocumentFixup acroFormFixup)
In this fix up you can reuse AcroFormOrphanWidgetsProcessor which
creates field entries from widgets.
I havn't tested that with your form but when we created this mechanism
we had in min dthat this should enable users of the lib to create their
own handling reusing some of the code we supply or creating from
scratch.

Weird, macOS Preview considers them as fields, making it possible to enter
data.
But happily, entering blanks, and then saving it (using macOS Preview),
makes them proper fields, and then PrintFields can see those fields. I'll
try that first next time :-)
Thanks for looking at it!

These fields are not in the acroform field list, that is why. This is
the acroform field list:
The page 2 "fields" only exist as annotations:
Something must have gone wrong when generating this PDF.
