Groups not showing in groups panel

[juejung]

Ubuntu 18.04 with Gnome desktop:
Installed from .deb file downloaded from https://builds.jabref.org/master/jabref_5.0.0-1_amd64.deb
JabRef version:
JabRef 5.0.0-dev--2019-10-21----0f0dce621
Linux 5.0.0-32-generic amd64
Java 12.0.2

Steps to reproduce the behavior:

1. Open JabRef
2. Open bibfile
3. Groups are not showing anymore in groups panel in latest development version

Cannot confirm. Works fine under windows. We didn't change anything related to groups

[Siedlerchr]

Works also fine under linux.
Note that it takes a moment to load the groups.

@Siedlerchr Ok, I can confirm that it works under Linux. The reason why groups disappeared was that my bibfile did not have the group info

@Comment{jabref-meta: databaseType:bibtex;}
@Comment{jabref-meta: grouping:
...

at the end of the file anymore. This happened when I upgraded from the JabRef development version from last week to the latest. Let's hope it was just an "upgrade glitch" and not something more severe with how the bibfile is saved etc.
I think this can be closed now.

This is odd. We didn't change anything to the groups stuff recently. Did you accidentally open the bib file with an older version of JabRef? (pre 5.0)

@Siedlerchr No I didn't. I keep an eye on it when I update to newer development versions to see whether it happens again.
One thing I did notice is that when I hit the save button in JabRef I keep getting the message "The library has been modified by another program" and the buttons "Dismiss changes" and "Review changes" appear. When I click "Dismiss Changes" nothing seems to happen and I do have my latest version that I just saved. My bibfile is stored in a shared Dropbox folder, so I suspect it might have something to do with that? I cannot think of any other external program making changes to my bibfile when I hit the save button in JabRef?

@Siedlerchr Nevermind, the saving issue is a known issue. #5085. This can be closed.
