Version: 25.2.6.2 (X86_64)
OS: Windows 11 X86_64
I created a form in LibreOffice Writer and placed a pattern field for an IBAN number.
The objective is to auto format the IBAN for better reading and only allow letters resp. numbers at the corresponding places.
In LibreOffice this works fine when i exit the design mode, the pattern is used an recognised. After Export to PDF with settings:
PDF version: PDF/A-3b
Create PDF form: checked (Submit format PDF)
this looses the formated settings in the PDF. Numbers can be written instead of letters and vice versa. Also the mask is not overwritten when something is entered.
What am I doing wrong?
