Jira behaviour script for priority change

[Sharadkumar Bangera]

Hello, 

How do i define a script in behavior field,

1)which should be executed only during the EDIT screen,

2)if priority is changed from major to minor, it should add comment in ticket " Priority changed from major to minor"

Plz help with the script

Hi @Sharadkumar Bangera 

1) You can check the action as in https://scriptrunner.adaptavist.com/latest/jira/behaviours-api-quickref.html#_getaction and then execute the operation only for edits

2) Adding automated comment should be handled via listener or postfunction. Behaviour ideally updates the form fields in the screen and is stored in jira only when the user presses the click buttons to go forward. That said, you can set the comment field text to a certain text using behaviours (more like a suggestive text which user can even edit before save)

Refer to https://scriptrunner.adaptavist.com/5.5.8/jira/behaviours-overview.html for more instructions on the apis
