Cannot choose channel when creating rule to trigger on Thing Event

[kvolden]

The problem

I have a fresh install of Openhabian, running Openhab 4.0.0 on a raspberry pi. I want to create a rule to trigger on a thing event. When creating the rule in the UI, I choose "Thing Event". As the thing I choose "Local Sun (astro:sun:local)", which I know for a fact produces events that I can also see at expected intervals in the events log. But when I then click on "channel" to choose the correct one, nothing happens. It doesn’t show a new dialogue, it’s just dead.

Expected behavior

A dialogue should open showing the different thing event channels to choose from.

Steps to reproduce

Click: Settings -> Rules -> (+) -> Add Trigger -> Thing Event -> Choose thing with events (Local Sun in my case) -> Channel

Additional information

I tried to work around this by manually adding the channelUID to the rule in the code tab, but it fails to trigger from the event, even though I have verified the event itself triggered from the logs. I'm not sure if this is a symptom of the same problem, or a different one.

[Alext73]

i had the same problem. Also on 4.0.1

[lolodomo]

Would be cool to have e fix for 4.0.2.

@lolodomo
I am waiting for an answer at openhab/openhab-core#3335 (comment).
The issue itself is easy to fix, but I need that answer.
