How do do you clear a value from a custom field single select list using scriptrunner post function?

[Suzanne Seaton]

I have a custom field single select list named 'Root Cause'. When I reopen an issue, then I want the value for 'Root Cause' to be cleared. I read through the Scriptrunner Set Issue Attributes documentation and while it provides code for text, date, user picker, system fields, checkboxes, and radio buttons I can't figure out how to do it for single select. I appreciate your help.

Hi Suzanne,

Try something like this:

import com.atlassian.jira.component.ComponentAccessor

def cf = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Root Cause")
issue.setCustomFieldValue(cf, null)
