Jabref: crossref resolution does not comply with biblatex specification

[sfo]

JabRef version

JabRef 5.0-dev--snapshot--2019-06-10--master--eb42850f7
Linux 4.4.0-150-generic amd64
Java 1.8.0_212

on

Ubuntu 16.04

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

Steps to reproduce the behavior

1. create a Proceedings entry Foo2019

@Proceedings{Foo2019,
  title  = {Foo Conference},
  date   = {2019},
}

1. create an InProceedings entry Bar2019 with crossref to Foo2019

@Proceedings{Bar2019,
  title  = {Bar Paper},
  crossref = {Foo2019},
}

1. have a look at the Bar2019 row at the main table view

Observed behavior

The year field of the Bar2019 entry gets populated with the value from the Foo2019 entry.

Expected behavior

All fileds (esp. year and journal/booktitle) get populated with values obtained from the crossref'ed entry.

Explanation

According to the biblatex documentation (Appendix B), the booktitle field of an InProcessings entry inherits the value from the title field of the referenced Proceedings entry.

As of now, JabRef simply takes the value of the same field from the referenced entry. These advanced mappings of biblatex are not yet taken into account.

The following code needs to be adapted:

Thanks to @CyraxSector this should be fixed now in the latest master.

Thanks for your effort. Unfortunately, this does not work for me in the latest master. See the attached MWE for testing.

Thanks to you this should be fixed in the latest development version 😸 . Could you please check the build from http://builds.jabref.org/master/. Thanks! Please remember to make a backup of your library before trying-out this version.
