Following on from #7652 :

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

Steps to reproduce the behavior:

1. Select options/preferences/Entry preview
2. click one of the selected styles in the right window
3. Get an Uncaught Exception popup window. Sometimes it takes one or two click to get the exception; I can't see quite what behaviour uniquely triggers it.

The event log is empty.

Still exists in latest development (you have to click on the various selected formats till the exception occurs).

@ThiloteE I encountered that as well. It has to do with the Edit-Field (coming from the richtextfx library) and the syntax highlighting feature. Did not yet find out why exactly it's happening. It seems to be coming when you don't have anything selected at all, e.g the list is empty At least that triggered it a few times

If you want to try this version, you can check the build here https://builds.jabref.org/pull/8110/merge/

Mhm not sure. Which list exactly are you talking about? - Something within the edit field or the selected list?

I can trigger the error pretty reliably in "selected" even when it is not empty, so not sure if the emptiness is a criterion. I can trigger it when selecting the styles via keyboard arrows and also when selecting them via mouse. I also get the error basically every time i click on customized preview style, but not always. Sometimes something seems to reset itself, i mean i guess that is to be expected, since the error message shows index issues.

Whereas in the older version (JabRef 5.4--2021-08-21--644e48d) prior to you having implemented the preview and edit function, the Available list did not trigger the error, now in the new version (JabRef 5.4-PullRequest8110.247--2021-10-01--9bc899a) it also triggers the error.

This bug is unfortunately coming from an external library, seems like it's FXMisc/RichTextFX#1021
But the fixed version is not yet released :(

Hey guys, sorry I didn't see this earlier otherwise I would have tried to publish a RichTextFX update sooner. Anyways version 0.10.7 is out now and Maven should reflect it in the next 24 hours.

The uncaught exceptions do indeed not trigger anymore in

JabRef 5.4--2021-11-08--1eaaf50
Windows 10 10.0 amd64

JavaFX 17.0.1+1

and they also did not trigger in the development version from yesterday.

Awesome!
