It is set to TRACE!
Thanks we should be able to fix this NPE.

But it was merged on 14.10.2019, 12:51, and snapshot 1725 was build on 15.10.2019, 5:55. ??
And snapshot 1725 has allegedly not this error! Maybe it was merged later (after 1725)?

Yes that’s what NPE stands for! Because they are so common they are abbreviated to NPE. 
The compiler can detect these at compile time when Java classes are properly annotated with null annotations. Though there’s still a lot of work todo to annotate them all.

Thanks for reporting and evaluating. I submitted a fix:

We are not talking about this. This is running (for controller settings)!
We are talking about this: Click on any zwave device, but not the controller:
Tools:(=“Werkzeuge” in german)
Controller: --> “Advanced Settings” are OK.
.
.
Any other zwave device: NOT OK
Just the menu for a non-controller device…
Not advanced…
Advanced…
However, I noticed that most of my devices are missing the configuration parameters section!

Thanx a lot!
But there are next NPE when I open Paper UI --> Configuration --> System
See this topic….

On Snapshot or M4? Which build??
On Snapshot 1731, but they built it about 7 hours later…
I guess there were no changes in between…
So, your post in the M4 thread is off-topic.

Usually there’s a new build because there are changes. There have been a few commits in core already. Now that M4 is out we will be merging riskier PRs as well.

I have had the same issue. The issue seems to be with zwave addon. If u downgrade your zwave addon to 2.3 it works again but obviously you then loose the updated zwave db
What snapshot did you download and why downgrade all the way to ancient 2.3?? 2.5 Milestone 4 works fine.
The snapshots were broken for z-wave but fixed several days ago, before Milestone 4 was released/.
If you are running snapshots you are supposed to report issues on GitHub because not all developers follow the forum. Otherwise you should be running a testing or stable version.
I will note the Z-Wave issue was fixed after somebody file an issue on GitHub and worked there to help troubleshoot things.
Since Snapshot 1731 it should run again…
