I am currently stuck on a project here due to the sometimes unpredictable and difficult to work with form field auto detection in Acrobat. I am designing a rather complex form in InDesign and exporting the PDF to have the form fields auto-generated in Acrobat.
Radio Buttons in particular are the trickiest to work with because of their demanding conditions. It is leading to a frustrating end-user experience when the radio button form fields get generated as circular check boxes which is intuitive and confusing. It seems to unexpectedly incorrectly interpret them as check boxes in some cases, and correctly interpret them in other cases even though the conditions are similar.
The Radio Button detection should be improved for more consistent results.
