3. Save as a new version
4. Close Okular.
5. Open the new version from Dolphin.
6. Click Show Forms. See my entered data.
7. E-mail to a Windows or Xubuntu user.

Fabio any clue? Seems the modification did not change the graphical data?

Note that Acrobat Reader and Evince are running on Windows. Document Viewer 3.6.0 using poppler/cairo (0.20.4) is running on Xubuntu.

Seems this is yet another XFA form with the same issue as https://bugs.freedesktop.org/show_bug.cgi?id=55978. XFA forms are not supported by Poppler yet.
Starting from Okular 0.16 + Poppler 0.22, you get a warning telling that this document contains XFA forms, which are not supported.

So, as long as I stick with Okular, I will be fine, but XFA form data cannot be shared with users of  Acrobat Reader, Evince, and Document Viewer? What will change in the next release is that I will be warned?

Poppler's non-XFA form support has been improved in 0.22, and because of those changes it happens that you will be able to share filled form data in this document with other poppler-based viewers, such as evince. *But* I discourage you from doing that, because when sometime in the future Poppler will start to support XFA datasets, it will probably behave like acroread currently does, i.e. it will show nothing. So my suggestion is to treat all XFA forms as unsupported, even though they appear to work.

> What will change in the next release is that I will be warned?
Correct. The exact message is "This document has XFA forms, which are currently unsupported", and it shown instead of the regular one "This document has forms. Click on the button to interact with them, or use View -> Show Forms.".
