Can anyone point me to materials or examples of how to append a text string to the history of an issue using ScriptRunner/Groovy. I believe that this would be as a Behaviour, not a Listener or Post action.
I've spent days in Google Search looking for examples and all I've come away with is don't use the ComponentManager in favor of the ComponentAccessor.
Jira v8.0.2 / ScriptRunner v5.5.7.1
Thank you.
