Hi Pablo,
First of all, my bad, the test suite example works just fine in Adobe,
including with ConTeXt latest.
I have messed up my form by overriding the PDF version to 2.0, shouldn't
have done that.
On the viewers, I cannot recall exactly what I've done earlier in the year,
but indeed, most likely I have tried evince after signing it from the
command line. From https://gitlab.gnome.org/GNOME/evince/-/issues/143 there
is still no support for the signing itself, though okular should have some
support.
In any case, thanks for the hints (I probably should've done more testing)!

Hi,
I cannot get the signature working either, but almost certain it did work in February this year, as I have done some with MKIV. [...]
Hi Adam,
I’m on a Linux computer, so I’m not able to check this now.
If the signature isn’t working, you mean that the output PDF document from fields-007.tex cannot be signed with Acrobat DC, don’t you?
Sorry for asking the obvious question, but this worked perfectly fine each time I tested.
Using the https://live.contextgarden.net/ with (LuaTeX 2.06 20200630 + ConTeXt MkIV 2020.06.30 17:30) looks good, but evince does not display the field.
Evince never displays the signature field, only when signed.
BTW, using mupdf-gl to sign the PDF document will mess it, since it has problems to recognize the child object.
From my experience, only Acrobat deals with child objects in signatures generating a valid signature (and rewriting the two objects into a single one).
Just in case it might help,
