Ther are two types of attachements, FileAttachements as annotations, or attachements as DataObjects, I tried.
I have to solve this problem:
Using JS, I have to import a FileAttachement into the my document, and the user has to open it, both in Acrobat pro AND in Reader (with form support).
(all cause of accessibility, using just a button).
In Acro pro I can use DataObjects to import an open, but, in Reader I can only open an attachement, but not add it.
Coul I therfore use FileAttachement as an annotation?
I tried this code, but there was no result in adding the the file.
