Thank you all for confirming the issue with macOS' Preview.
My version is the same as Thad's: 10.1 (944.6.16.1).
Just to be sure, I've also downloaded:
- PDFpen 11.2.1
- PDFelement Version 7.5.9.2925.5262(20200214)
and the issue is only reproducible in macOS' Preview.
All the other PDF viewers treat the flattened PDF document as flat,
where you can't check the checkboxes after flattening.
Should this issue be raised somewhere? (With Apple maybe?)
Yes, please submit the file to apple. Ask them if there is anything that
can be done by software like ours so that that Mac Preview won't treat
this as a form field. (Why is this named "preview" if one can change
things?!)
I don't see a need for the FAQ at this time, but that's just me.

Does it need to be documented somewhere, like in the FAQ, so that others
don't stumble on it?
Because I implemented this functionality a while back, when .flatten became
available as part of PDFBox,
but I only tested the PDFs with Preview and assumed that maybe I'm doing
something wrong, because I
could still modify the checkboxes.
Thank you all for your help

I'll take some of that back--I can add new checkboxes, but I can't remove
checks placed before flattening.

I am seeing the same behavior that Dick is seeing with Tillman's file in
Preview (Version 10.1 (944.6.16.1)), but not with a file of my own.
In the past two weeks I was asked to write program to fill in a PDF form
from a file of name:value pairs, and flatten it. I
used ((PDCheckBox)pdField).check() and ((PDCheckBox)pdField).unCheck()
for
the checkboxes and pdField.setValue(value) for others of field type "Btn"
and for "Tx", then flattened and saved the result with
acroForm.flatten();
pdfDocument.save(outpdf);
pdfDocument.close();
The resulting file in truly flat. I cannot alter the checkboxes or any
other field in Preview.
The original form was created on a Mac with PDFpenPro, but I don't know
the version. I can post my code if desired, but I can't release the PDF
without permission, and the person responsible for it is out of the
office
all next week.

Aleksandar and Tilman,
I was curious as I use MacOS. I opened Tilman's result file in
Preview. I
was indeed able to place a checkmark in the checkboxes. Interestingly,
I
could also drag the checkmark around out of the box. I opened the file
(saved in Preview with 2 checkboxes checked) with Adobe Reader (Mac),
Acrobat X (Win7), and PDFCreator(from Nuance; Win7). I all 3 of those,
the
checkboxes were disabled (couldn't set a checkmark) but, interestingly,
I
still could drag the checkmark out of the box. So, it does look like
idiosyncratic behavior of Mac Preview app.

What PDFBox version are you using?
I was using 2.0.16
https://github.com/dotemacs/pdfboxing/blob/flatten-form/project.clj#L7
I tested it with the trunk and it works fine.
Here is my Java code:
https://gist.github.com/ff9fb8ccf11abeb2ac6c1c461f2c1eb9
Compiled it with PDFBox 2.0.18 and commons-logging 1.1.2.
Opening it in macOS' Preview PDF viewer, I can still check the
checkboxes.
But *not* in Adobe's Acrobat Reader DC version 2020.006.20034.
The upgraded the Clojure project and the behaviour is the same:
- I can check the checkboxes in Preview
- I can't check the checkboxes in Acrobat Reader DC
What PDF viewer did you use to verify the flattening ?
Adobe Reader DC.
Here's my result file:
http://www.filedropper.com/interactiveform-saved
I looked with PDFDebugger, there are no more checkbox fields.
Please try with that file.
If my file brings the same effect, then I'd say this is a weird
behavior
of MacOS Preview. Maybe it transforms anything that looks like a
checkbox into a field?
Btw using getFields() is not correct (see javadoc why)
Looking at:
https://pdfbox.apache.org/docs/2.0.13/javadocs/org/apache/pdfbox/pdmodel/interactive/form/PDAcroForm.html#getFields--
(Note: 2.0.13 is the latest documentation linked from
https://pdfbox.apache.org/ )
Is the reason that .getFields returns only the top level fields and
not
the
nested ones?
So I'll have to loop through them to flatten all the child fields?
No, this is more a general observation. I don't think you have to set
then readonly at all.

Thank you for your time

Hello PDFBox users
I'm trying to flatten a PDF form so that it's no longer editable.
I can flatten the text fields, but the checkboxes are still
editable
(you're able to check them).
I am doing this in Clojure, but that should not (I hope) do
anything
special
I get a PDF, get its forms and then I set them to read only.
Is there a step that I'm missing?
The code in question is here:
https://github.com/dotemacs/pdfboxing/commit/d62a3da18de258a5ca596b22cfa42d4552de9d60
The form I'm trying to edit is here:
