Rules OH4 don't open trigger channels

[Linux2fast (Andreas Dollinger)]

Hello,
since the transition to openHAB 4.0.1, it is no longer possible to open channels in the Rule Engine.
I have a rule that uses the Astro Binding to lower my blinds at sunset. This worked in OH3.6.
When adjusting the rule, I noticed that I can use the trigger “Astro:Sun:Local” but the channels and the UI cannot be opened.
my code is

configuration: {}
triggers:
  - id: "1"
    configuration:
      thingUID: astro:sun:local
      event: end
      channelUID: astro:sun:local:set#event
    type: core.ChannelEventTrigger
conditions: []
actions:
  - inputs: {}
    id: "2"
    configuration:

Have another User this Problem?

Yes - me, GUI is not working…
As workaroud I define the needed channel directly in the code tab.
Eg.

configuration: {}
triggers:

• id: “1”
  configuration:
  thingUID: mqtt:topic:MQTT:Buttons_Remotes
  channelUID: mqtt:topic:MQTT:Buttons_Remotes:c_RC_IKEA_2
  type: core.ChannelEventTrigger
• id: “3”
  configuration:
  thingUID: mqtt:topic:MQTT:Buttons_Remotes
  event: “”
  channelUID: mqtt:topic:MQTT:Buttons_Remotes:c_Btn_Living

This sounds like a UI regression. Please file an issue on the UI repository.

There will be times when you discover a bug in OH. This tutorial explains how to file an issue so the developers can know about the bug and hopefully fix it. Do I Have a Bug? openHAB is a complex system with lots of options and ways to configure various capabilities. As the old saying goes, openHAB gives you a lot of rope with which to hang yourself. So how do I as an average user know whether I’ve done something wrong or if there is a bug? The good news is we don’t expect you. Step 1: Ask fo…

Me three. I can’t add a new thing channel trigger via the UI but using the ‘code’ tab I can copy and paste from another rule. Has anyone with a github account posted this yet?

@Tougharms

Has anyone with a github account posted this yet?

Yes.

Cannot choose channel when creating rule to trigger on Thing Event

Thank you🙏

First and foremost, Thanks @JustinG for raising the issue!
I just updated my OH4 from 4.0.2 to 4.0.3 and on my side, this fixed the issue!
