How to retrieve linked issue custom field values to parent issue.

[Ash]

Hi All,

Is there any way I can pull linked issue values to parent issue.

For example, A is a parent issue and B is linked to A. Is there any way we can retrieve Issue B custom field values in Issue A. 

TIA!!

[Ash]

Below is the code I'm using 

import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue

def Issue issue = issue

def User user = ComponentAccessor.getUserManager().getUserByName("username").getDirectoryUser()
def issueLinkManager = ComponentAccessor.issueLinkManager

def linkCollection = issueLinkManager.getLinkCollection(issue, user)

if (linkCollection && linkCollection.allIssues) {
def CustomFieldManager customFieldManager = ComponentAccessor.customFieldManager
def customField = customFieldManager.getCustomFieldObject("customfield_xxxx")
def linkedIssue = linkCollection.allIssues.first()
return linkedIssue.getCustomFieldValue(customField)
}

I get the error at the underlined code.

Hi Ashish,

Were you able to figure it out or do you still need help with this issue?

Hi Ash,

You could create a scripted field that gets values from issues  that are linked. For example, if Parent issue A was of type "Bug", the code for your scripted field would look like this:

import com.atlassian.jira.component.ComponentAccessor
def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def customFieldManager = ComponentAccessor.getCustomFieldManager()
if (issue.issueType.name == "Bug") {
    issueLinkManager.getOutwardLinks(issue.id).first() { issueLink -> // go through all issues linked off of the Story
        def linkedIssue = issueLink.getDestinationObject()
        def customField = customFieldManager.getCustomFieldObjectByName("customfield_xxxx")
        return linkedIssue.getCustomFieldValue(customField)
    }
}

Hi Joshua,

Thanks for your code, I see cannot find matching method error at line 5 as shown

Hi Ash,

Sorry about that, that script contained a small error.

However, I think that script will not work for you anyway. Could you clarify the relationship between Issue A and Issue B? Is this correct:

• Issue A is the parent issue
• Issue B is a sub-task of Issue A

In that case, a script like this should work:

import com.atlassian.jira.component.ComponentAccessor
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def subTasks = issue.getSubTaskObjects()
def childCfValue
if (subTasks) {
    issue.getSubTaskObjects().each { subtask -> // go through sub-task issues
        def customField = customFieldManager.getCustomFieldObject("customfield_12220")
        childCfValue = subtask.getCustomFieldValue(customField)
    }
}
return childCfValue

Issue A is a Parent issue and Issue B is a linked issue to the parent issues.

Thank you,  I will try this code and update you.

Hi Joshua

Can I get the script for linked issues? I am trying to get it for a linked issue which should have a custom text field filled. If it is empty, my validator should through error. 

Above script is working for subtasks. I tried to change it for linked issues but in vain, the linked issues script is not working, throwing error as shown in above screenshot of Ash
