Incoming Value Transformation of a copied channel cannot be changed to a new value inside copy process

[matmai]

The problem

If a channel of a thing of type generic MQTT Thing is copied via the main UI to a new channel the values are correctly copied. But if the already prefilled Incoming Value Transformation is altered to a new value and the channel is saved the Incoming Value Transformation stays the same (as copied from the previous channel).

Expected behavior

It is expected that the copied values could be adjusted and saved to the newly created channel.

Steps to reproduce

1. Create a thing of type generic MQTT Thing and a channel with an Incoming Value Transformation
2. Copy this channel via Copy Channel functionality
3. Alter the prefilled value of Incoming Value Transformation
4. Save the channel
5. Check if the adjustments of the Incoming Value Transformation are saved

Your environment

runtimeInfo:
  version: 4.2.1
  buildString: Release Build
locale: de-DE
systemInfo:
  configFolder: /etc/openhab
  userdataFolder: /var/lib/openhab
  logFolder: /var/log/openhab
  javaVersion: 17.0.12
  javaVendor: Raspbian
  osName: Linux

Browser console

Nothing that looks like an error, just "Thing updated according to SSE, reloading"

Browser network traffic

There are no failed requests

Additional information

As a workaround the channel has to be edited and saved again. Then the new values for Incoming Value Transformation are saved as expected.

It is still the case with v4.3.0, not fixed by !2891.

Cannot reproduce this.
What is your Main UI commit? It should be displayed on the about page if Main UI has been properly reloaded after the update to 4.3.0.

I retestet the issue with two different browsers again and now it is working and I cannot reproduce the problem any more.

Is it possible that some parts of the main UI had been still be left in the browser cache during my first test directly after installing the new OH version?

Yes, to be sure always perform „clear cache and reload“ (if available) after an upgrade.
