I’m using Writer 220.127.116.11 on Win10 x64.
When exporting a PDF form, the formatting is lost in the exported PDF, and in most cases the default value.
I am exporting with Submit Format = PDF, meaning the form data entered will be saved within the PDF.
In the LO form control dialog, for example, a Date control can be set to a format of ‘DD/MM/YYYY’. However when this is exported to PDF and examined in Acrobat, the resulting field has a ‘Select format category’ of ‘None’.
My workaround, as with other LO form issues, is to post-process in Acrobat to enforce the format. Simply changing the format to a date option enables the date-picker within Adobe Reader, which is great for users.
A similar issue occurs with the Default value - this gets lost on PDF export for Date, Time and Numerical fields. When I tested a Formatted field, configuring it for currency, the default was properly retained in the exported PDF.
