Jira Read Only field using Behaviors

[Jon Kocen]

I tried using the Adaptavist script from their libary

I put this into a post function but only get an error can't operate on a null field for getFieldByName() 

Am I using this wrong, can it be used in a post function to make a field read only? I need to stay in the same status for business reasons.

import com.atlassian.jira.issue.IssueFieldConstants

import com.onresolve.jira.groovy.user.FieldBehaviours

import groovy.transform.BaseScript

@BaseScript FieldBehaviours fieldBehaviours

final String fieldName = "TextField"

// get field by name and make it read only

getFieldByName(fieldName).setReadOnly(true)

// get field by id and make it read only

getFieldById(IssueFieldConstants.DUE_DATE).setReadOnly(true)

I think I figured this out. I ended up adding a Behavior with no options selected just some Server Side Script

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.security.roles.ProjectRoleManager

def projectManager = ComponentAccessor.projectManager

def projectRoleManager = ComponentAccessor.getComponent(ProjectRoleManager)

// get user

def user = ComponentAccessor.jiraAuthenticationContext.getLoggedInUser()

// get project

def thisProject = issueContext.getProjectObject()

// get user's roles for this project

def projectRoles = projectRoleManager.getProjectRoles(user, thisProject)

def RI = false

def BP= false

// if RRI or BP, you can still edit

if (projectRoles.find(){it.getName() == "RI"}) { RI= true }

if (projectRoles.find(){it.getName() == "BP"}) { BP= true }

// get CT value

def CTValue = getFieldByName('CT').value

// get CoT

def CoT = getFieldByName("CoT")

// get CLV value

def CLV = getFieldByName("VLV").value

// set to read only if roles and field values match

if (CLV== 'Yes' && !RI && !BP) {

    // make read only

    CoT.setReadOnly(true)

}

else {

    CoT.setReadOnly(false)

}

Hi Jon,

I don't think you can use these method (getFieldByName, getFieldById..) in postfunctions, only in behaviours. The context is different in both cases.
