Bibliography cannot be updated

[ureber]

JabRef version 4.3.1 / 5.0-dev on Ubuntu 18.04

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

When updating the bibliography in LibreOffice Writer I got an error (see below). It is possible to add references to the text, but not to update the bibliography.

I would very much appreciate if you can look into that. Thanks!

Hi,
thanks for the bug report.
Do you use any custom style (if yes, could you please upload it here, just add the extension .txt)
And do you use bibtex or biblatex mode?

[ureber]

Thank you for the quick response.

I use Bibtex mode (default) with the following style file.

APA6_en.txt

[ureber]

Maybe it doesn't matter, but what I get in the console is [JavaFX Application Thread] ERROR org.jabref.logic.citationstyle.CitationStyle - Can only load style files: Preview.

[Siedlerchr]

I found a way to reproduce the error message. The problem is that you have a reference to an entry in the library which is no longer there
e.g. Insert citation Nie et al. [2017] with bibtexkey Nie2017. If you now remove this entry from your library it will lead to the error.

I prepared a fix. In a couple of minutes you can try out this version:
https://builds.jabref.org/ooLogging/

To identify the culprit an error message will the shown which shows the OO reference mark of the bibtex entry

[ureber]

Perfect! When I add the missing entries, everythins is back to normal. The comment with the missing reference mark is very helpful. Thank you!

[Siedlerchr]

@ureber Thanks for the feedback, the fix is now also merged, so it will be also available in the latest master as well in a couple of minutes.
