Bug ID: 474889
Summary: Form field misuse leads to 'NaN' which won't disappear
Classification: Applications
Product: okular
Version: 23.08.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: PDF backend

The problematic document
I have a pdf document with a form field that should (I guess) only accept
numbers. By deliberate entering a non-digit I can make it show NaN.
Afterwards, it is not possible to remove this NaN again.
STEPS TO REPRODUCE
1. Open the attached document; click on 'show forms'
2. Click on the top left square (below "70 Liter")
3. Enter the letter X
4. Click outside of that square --> the X changes to NaN
5. Click into the square again --> the NaN changes back to X
6. Replace the X by a 2
7. Click on "hide forms"
OBSERVED RESULT
Instead of the number "2" the "NaN" is shown again.
EXPECTED RESULT
I am not quite sure what to expect. Should I be prevented from entering
non-digits in the first place? At the very least I would expect to see a "2"
at the end of the seven steps, not NaN.
