Updating a select list value by changing another select list value

Question

Hi All,

I have created a script which allows to update a select list A by changing the value of a select list B. However, it is not working, please suggest:

import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.jira.groovy.user.FieldBehaviours
import com.onresolve.jira.groovy.user.FormField
import groovy.transform.BaseScript

@BaseScript FieldBehaviours fieldBehaviours

FormField selectList1 = getFieldById("customfield_20650") 
FormField selectList2 = getFieldById("customfield_20156")

def selectList1Val = selectList1.getValue()

if(selectList1Val.toString().contains("Australia")){

selectList2.setFormValue(17305)
}

error in logs:

java.lang.NullPointerException: Cannot get property 'customfield_20650' on null object
at com.onresolve.jira.groovy.user.FormField.getValue(FormField.groovy:181)
at com.onresolve.jira.groovy.user.FormField$getValue.call(Unknown Source)
at Script38.run(Script38.groovy:17)

What Am i doing wrong here? Please help

Yes, the field is on the screen.

Thanks Alexey, I think the View screen is the issue here

Behaviours do not work with view screens. They work only with Create, Edit and Transaction screens. What screen do you open when you get the error? Are you sure the field is in that screen?

I am using  this script inside the behavior plugin as a serverside script. Also, the field already has a value on the "View" Screen of the ticket and is mapped with the project and ticket type.
