I can't believe this error, but when I use InDesign to set several fields to be "Required" I am able to submit the form or print it from Acrobat Pro or Reader without any alert notice telling me the fields need to be set.
The fields are checked as Required in the Acrobat Properties db.
However, when I add a field to that PDF using Acrobat's field tools and then try to print or submit, I get an alert.
It seems that the Required fields are broken from ID.
Sandee, it is a known issue.
Just wanted to share a quick work around.
After exporting the PDf-Form, if you once click on ‘Clear Form’ (either through ‘Clear form button from ID or Tools>>Forms>>Clear Form in acrobat’), the issue is resolved and ‘Required’ property is honored for text fields.
Thanks and regards,
