Diseable edition for severity if issue is in JQL Filter with scriptrunner ( Behaviour)

[Nairi salma]

Hi

I want to diseable edition for severity if issue is in JQL Filter with scriptrunner ( Behaviour) 

I wrote this script  but  diseabling edition didn't work . I tested my script on the script console and i had all issues needed

import com.atlassian.jira.bc.issue.search.SearchService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.jql.parser.JqlQueryParser
import com.atlassian.jira.web.bean.PagerFilter

def searchService = ComponentAccessor.getComponent(SearchService)
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def queryParser = ComponentAccessor.getComponent(JqlQueryParser)

def query = queryParser.parseQuery("project = 'DCIW387 GET' AND issue in under_sync_by_connection('GETSync')")
def search = searchService.search(user, query, new PagerFilter())
def severity= getFieldByName("severity")
def priority = getFieldByName("Priority")


search.results.each {
// do something with each issue
severity.setReadOnly(true)
//priority.setReadOnly(true)
}

thanks a lot
