Cannot invoke "javafx.beans.InvalidationListener.invalidated(javafx.beans.Observable)" because "<local1>[<local5>]" is null

[ryan-carpenter]

JabRef version

Latest development branch build (please note build date below)

Operating system

GNU / Linux

Details on version and operating system

openSUSE Tumbleweed with KDE Plasma 6.0.5

Checked with the latest development build (copy version output from About dialog)

• [X] I made a backup of my libraries before testing the latest development version.
• [X] I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Click on a group
2. Edit a group?
3. Click on another group

Also, the exception

• does not seem to apply to a specific group or group-type
• does not occur consistently when returning to the same group that led to the exception
• occurs when there is or is not text in the search bar
• resolves after restarting JabRef and re-opening the library
• eventually recurs after restarting
• sometimes opens many copies of the uncaught exception message box
• seems to happen after editing a group, but this may be coincidental
