Scriptrunner Behaviour shared validator script

Question

I have multiple fields that need tha same validation script run. My case is complex but let's say I've got 10 numeric fields and when any of them change, an 11th fields will be updated with the sum of fields 1 to 10.

Do I do "code reuse" via copy and paste, or is there a better way?

I need both, but ended up using listener + javascript in field description.

I wanted a real-time update of the fields as the user was editting them but also needed to create a listener to cater for cases where one of the fields are edited via other means.

Javascript works a bit better than behaviours for this as it can all run locally, but I needed to split my code across 3 fields as it was too big. Not a great solution but it works.

Why you tried using "Script Listerner" for this scenario? i.e. writing a custom listener. - https://scriptrunner.adaptavist.com/5.0.0/jira/listeners.html

Or  do you need to use Behaviour?
