how does CustomFieldUpdatedEvent work?

[Torbjörn Richter]

Im would like to check whenever a dropdown value is changed and then perform an action but I cant find any sample code on this matter.

Anyone with experience on this event listener?

This event triggers when a customfield's configuration is updated, as well as the description of the field or the field name.

I think that you wanted this to detect a change on the value of a customfield in a create or edit screen. Maybe you can do this with a watcher or a behaviour.

I attach a screenshot of an example.

Yes, the screenshot just shows you the event that I said.

You can do this with a behaviour, I leave you here some documentation that can help you -> Behaviours
