Is there a way in Groovy script to determine IF a multi select list changed?

Question

Is there a way to determine if a multi select list changed in any way?  I know how to check if it contains a certain value, but I want to trigger if there was a change (or ideally if it didn't contain a certain value previously).

I'm doing this as part of a Custom Email Send from Script Runner.

Figured it out...

cfValues['Assignee Group']*.value.contains('Platform') && changeItems.any {

it.field == 'Assignee Group'

}

I would suggest to have previous selection saved in a hidden field and then compare it with the current selection. You can have field which is not visible on view/edit screen if you don't add it to these screens.
