Copy custom field data to a linked issue using groovy

[Jeremy Schrecengost]

I have a ticket that has 10+ custom fields when that ticket transitions to a specific state I want to copy that data to the same custom fields for all the linked tickets (with a specific link type).

I have JMWE and that allows me to add a post function to do this but I would need to do one for each custom field. (unless someone knows how to adjust that)

What is the groovy code to access Custom Fields of a linked issue? I have been searching and I can only find how to create a link.

How to get linked issues:

def issueManager = ComponentAccessor.getIssueManager() 
def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def outwardIssueLinks = issueLinkManager.getOutwardLinks(issue.getId())

if (subOutwardElements.size() > 0) {
    for (def i = 0; i < subOutwardElements.size(); i++ ) {
       def linkedIssue = issueManager.getIssueObject(subOutwardElements[i].destinationId)
    }
}

Once you got the linkedIssue, you access it's customfield same way as you would access any regular issue (it's anissue object), so:

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def myCustomField = customFieldManager.getCustomFieldObject("customfield_14949")

def linkedIssueCustomFieldValue = issueManager.getIssueObject(linkedIssue).getCustomFieldValue(myCustomField)

Is there a way to only grab linked issues of a specific type? like "Is a copy of" 

[Jeremy Schrecengost]

Also you have 

subOutwardElements.size

I am not seeing that defined anywhere should that be outwardIssueLinks?

[Nir Haimov]

Answer for both of your questions:

1. to search for specific link type:

def subOutwardElements = outwardIssueLinks.findAll { it.issueLinkType.name.contains("Is a copy of")}

2. In #1 you have the  "subOutwardElements"

Here's the code:

issue.getLinkedIssues("Is a copy of").each {
  it.setFieldValue("my field", issue.get("my field"))
}

Since you're using JMWE, you can create a Scripted (Groovy) post-function, and on JMWE the code is much easier. I'll post an example later today
