Created attachment 173082 [details] PDF document with form SUMMARY I will attach a PDF document which has an embedded form. There are two "date" fields which can be filled out in "Show Forms" mode. When that mode is exited and/or the PDF is printed no value is displayed for these fields. Saving the filled out document and opening it in Firefox (ie. pdf.js) shows the previously entered values. STEPS TO REPRODUCE 1. Start Okular 2. Download the form from https://www.hamburg.de/resource/blob/35658/bf5a89315bba109b3a8664d1ed4adcb1/arbeitszeitennachweis-kindertagespflege-data.pdf or use the attached version 3. Click the "Show Forms" button to switch to edit mode 4. Type in some value for "Name des Kindes" 5. Type in some date for "Geburtsdatum des Kindes". Like 01.01.1970 6. Leave the edit mode again by clicking "Show Forms" 7. Observe that the name will stay but the date will disappear (there is another date-like field "Beginn der Arbeit" which shows the same behaviour) 6. Save the file and close Okular 7. Open the file in Firefox 8. Observe that the values are filled out 9. I couldn't find an option to leave the edit mode there. But the value will stay visible in the print preview via Ctrl+P OBSERVED RESULT The values for those "date" fields disappear when the form edit mode is not active. Neither are they visible on a printout. EXPECTED RESULT The values should not disappear.

Can confirm with Okular 23.04.2.
pdftoppm does not show the date either. Is this rather a poppler bug, then? pdftoppm prints Syntax Error: Unknown font tag 'Helvetica' Syntax Error (315229): No font in show This may be where to start looking.
I opened a corresponding poppler issue with some additional information at https://gitlab.freedesktop.org/poppler/poppler/-/issues/1529. However, it is not clear at this point whether this is really a poppler problem.
