Scripted field to show name of Sprint on linked issue

[Joleen Kantola]

I'm trying to create a scripted field that shows the name of a Sprint on a linked issue.  I've gotten the field to work with the following code, but there is a type checking error for "name" in the line shown in bold.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.CustomField

def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def linkedIssues = issueLinkManager.getOutwardLinks(issue.id)

CustomField customField =  ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_11941")

if (customField != null) {
    for (issueLink in linkedIssues) {
        if (issueLink.issueLinkType.getOutward() == "Caused By") { 
            def linkedIssue = issueLink.destinationObject
            return linkedIssue.getCustomFieldValue(customField).name[0]
        }
    }
}
return null

Is it okay to ignore the type checking error, or is there a better way to get the name of the Sprint?

Thank you!

Hello @Joleen Kantola
It is okay to ignore that error.

This is happens because getCustomFieldValue may returns different types of objects like ApplicationUser, Issue, Option etc. And compiler doesnt know what type exactly have this customfield, so it shows you error.

But in runtime it work with certain object and if this object has a method (name[0]) it will work.
