CreatingLink using Issue Link field (Inward/Outward Link)

[Joe Yesh]

Hi Team,

I have IssueType called 'Initiative' & 'EPIC', whenever I create an EPIC I will link Initiative using Issue link picker field type 'Initiative Link', as part of this process I want to link the same issue whatever I selected as 'Initiative Link' to be linked to my EPIC as 'child of' & same should be viewed in the issue link section of 'Initiative' with 'parent of' relation, in attempt to do this, I have created behavior for the field 'Initiative Link', so whenever this value is selected during create/Edit, it should update the issue-links with the same issue selected.

I have written the code like this, but I get an error when I run in console & same is not working in behavior too, not having any compilation error though but get some run time error
---------- 'org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'ABC-1617' with class 'com.atlassian.jira.issue.IssueImpl' to class 'java.lang.Long'
at Script784$_run_closure1.doCall(Script784.groovy:16)
at Script784.run(Script784.groovy:14)' ---------------

My code is
---------------------------------------------------------------------
---------------------------------------------------------------------
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.component.ComponentAccessor
def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def issueManager = ComponentAccessor.getIssueManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def jiraAuthContext = ComponentAccessor.getJiraAuthenticationContext()
def long tpIssueLinkType = 12030
def MutableIssue cfIssue
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
CustomField customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_14771")
Issue issue = issueManager.getIssueByCurrentKey("ABC-1703")
issue.getCustomFieldValue(customField).each

{ iscr -> cfIssue = issueManager.getIssueObject((Long)iscr) issueLinkManager.createIssueLink(cfIssue.getId(), issue.getId(), tpIssueLinkType, 1L, currentUser) }

thanks,

Though this is working when I modify/update the 'Initiative Link' field in the existing issues, but not working when I create a ticket having the same 'Initiative Link', also I need this to remove if existing any '12030 ' issue link and add updated Initiative Link.

import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.issue.IssueEvent

def issueLinkManager = ComponentAccessor.getIssueLinkManager() 
def issueManager = ComponentAccessor.getIssueManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def long tpIssueLinkType = 12030 // Initiative Issue Link
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

CustomField customField = customFieldManager.getCustomFieldObject("customfield_14771") // Initiative Link Field
Issue sourceIssue = issueManager.getIssueByCurrentKey(underlyingIssue?.getKey()) // Get Underlying issue key
sourceIssue.getCustomFieldValue(customField).each {
iscr -> 
def cfIssue = issueManager.getIssueByCurrentKey((String)iscr)
issueLinkManager.createIssueLink(cfIssue.id, sourceIssue.id, tpIssueLinkType, 1L, currentUser)

}
