How to make linked issues field mandatory for specific conditions and project - JMWE

[subham_p]

Hi there, 

I am trying to get the following scenario to work. 

• If customfield_1234 = "XYZ" then Linked Issue is required
• at the same time linked issues should only allow issues from the ABC project

I am trying out the below validators. However, the #2 validation is blocking the transition when some other values are selected in the custom fields. 

1. Fields Required Validator - Linked Issue mandatory with condition customfield_1234 = "XYZ"
2. Scripted (Groovy) Validator -  with the following script

import com.atlassian.jira.component.ComponentAccessor
import webwork.action.ActionContext
 
def fieldManager = ComponentAccessor.fieldManager
def issueManager = ComponentAccessor.issueManager
def linksSystemField = fieldManager.getField("issuelinks")

def request = ActionContext.request
def params = request.parameterMap
def issueLinkingValue = linksSystemField.getRelevantParams(params)

def linkedIssues = issueLinkingValue.linkedIssues
def linkedIssueProjects = linkedIssues.collect { issueManager.getIssueObject(it).projectObject.key }

linkedIssueProjects == ["ABC"]
