first sample form

For some PDF forms, text inserted into text form fields is not rendered at all. I am attaching two sample files. The text is shown correctly when using for example Adobe Reader to fill the forms.

Steps to reproduce:

1) open sample file with Okular or Evince
2) insert text into form field (e.g. "Startbahnhof" in first file, "Vorname und Nachname" in the second sample file)
3) switch to next field

Result:

The inserted text is no longer shown. It also does not show in a printout.

Expected result:

The text inserted into the form value is shown and is also present in a printout.


Note: The original bug report was filed against Okular: https://bugs.kde.org/show_bug.cgi?id=331697
That bug report contains more information and an analysis of what is malformed in the two PDF files as far as I can see.

It was suggested there that a bug against Poppler be opened instead so that the handling of such files can be improved.

Thanks, Albert!

I did a quick retest with Poppler's current master branch (as of commit 8c8c0034).
The second sample form works nicely now.
However, the first sample form (which has a different root cause) still shows the same problem.

Should I open a separate bug report for that one?

@Albert: Sorry, I had forgotten to add you in CC with my previous comment, so not sure whether you actually noticed it (s. above).

Should I create another bug report for the document that's not working yet?

No need to CC me i see all poppler bugs.

Can you please try again? With poppler master and okular master (okular shouldn't really matter) I get it to work as shown in https://www.youtube.com/watch?v=zIPUjqR68q8

Sorry for the noise! I just tried again and it does actually work; no idea what I did wrong yesterday...
