[Script Runner] Post function to link back to issue

Hello.

I'm trying to adapt a script from the following website:

http://www.denizoguz.com/2013/06/29/jiraautomatically-linking-issues-with-a-script-during-create-transition/

Even though I don't know groovy, nor java, I somehow (thanks to google and atlassian developer site) made it to the point where script enters succesfully the last "if". Now I'm experiencing the problem than I can't find solution to. One of the last statements of the code throws following error:

2013-08-07 11:16:37,977 Thread-997 DEBUG test_user 676x14687x1 fm4ix2 ***.***.***.*** /secure/QuickCreateIssue.jspa [onresolve.jira.groovy.PostFunction] Script executed this code
2013-08-07 11:16:37,977 Thread-997 ERROR test_user 676x14687x1 fm4ix2 ***.***.***.*** /secure/QuickCreateIssue.jspa [onresolve.jira.groovy.GroovyRunner] The script failed : javax.script.ScriptException: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: IssueLinkTypeManager for class: Script13
2013-08-07 11:16:37,977 Thread-997 ERROR test_user 676x14687x1 fm4ix2 ***.***.***.*** /secure/QuickCreateIssue.jspa [onresolve.jira.groovy.GroovyFunctionPlugin] Error executing post-function
javax.script.ScriptException: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: IssueLinkTypeManager for class: Script13

I'm afraid I need some help. Can anybody tell me what I'm doing wrong? I also don't understand this statement:

def issueLinkTypeManager = componentManager.getComponentInstanceOfType(IssueLinkTypeManager.class);

Am I wrong or is it trying to get some parameter of variable during definition of the very same variable? Or is IssueLinkTypeManager (with capital "i") some api interface, and issueLinkTypeManager just a variable?

What should I do to make the code work properly? Here is the whole script:

import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.component.ComponentAccessor;
import org.apache.log4j.Category;
import com.atlassian.jira.issue.IssueManager;
def Category log = Category.getInstance("com.onresolve.jira.groovy.PostFunction");
log.setLevel(org.apache.log4j.Level.DEBUG);

def ComponentManager componentManager = ComponentManager.getInstance();
def customFieldManager = componentManager.getCustomFieldManager();
def parentTaskIDCF = customFieldManager.getCustomFieldObject('customfield_12101');//write your own custom field id here
def parentTaskID = issue.getCustomFieldValue(parentTaskIDCF);
if (parentTaskID == null || parentTaskID == '') {
    return true;
} else {
    def issueManager = ComponentAccessor.getIssueManager();
    def parentIssue = issueManager.getIssueObject(parentTaskID);
    def isParentIssueValid = (parentIssue != null);
    if (isParentIssueValid) {
		log.debug "Script executed this code";
        def issueLinkManager = ComponentAccessor.getIssueLinkManager();
        def issueLinkTypeManager = componentManager.
                getComponentInstanceOfType(IssueLinkTypeManager.class);
        def issueLinkType = issueLinkTypeManager.
                getIssueLinkTypesByName('Relates').get(0);
        def authenticationContext = componentManager.
                getComponentInstanceOfType(JiraAuthenticationContext.class);
        issueLinkManager.createIssueLink(
                issue.id, parentIssue.id, issueLinkType.id, 1L, authenticationContext.user);
    }
}

Thanks in advance!

Try this:

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.link.IssueLinkTypeManager
import org.apache.log4j.Category

MutableIssue issue = issue
Category log = log

log.setLevel(org.apache.log4j.Level.DEBUG);

def ComponentManager componentManager = ComponentManager.getInstance();
def customFieldManager = componentManager.getCustomFieldManager();
def parentTaskIDCF = customFieldManager.getCustomFieldObject('customfield_12101');//write your own custom field id here
def parentTaskID = issue.getCustomFieldValue(parentTaskIDCF);
if (parentTaskID == null || parentTaskID == '') {
    return true;
} else {
    def issueManager = ComponentAccessor.getIssueManager();
    def parentIssue = issueManager.getIssueObject(parentTaskID);
    def isParentIssueValid = (parentIssue != null);
    if (isParentIssueValid) {
        log.debug "Script executed this code";
        def issueLinkManager = ComponentAccessor.getIssueLinkManager();
        def issueLinkTypeManager = componentManager.getComponentInstanceOfType(IssueLinkTypeManager.class);
        def issueLinkType = issueLinkTypeManager.getIssueLinkTypesByName('Relates').asList()[0];
        def authenticationContext = componentManager.jiraAuthenticationContext;
        issueLinkManager.createIssueLink(issue.id, parentIssue.id, issueLinkType.id, 1L, authenticationContext.getLoggedInUser());
    }
}

There was an import missing. I also made some small other adjustments. I assume that the parentTaskIDCF contains valid issue id, correct?
If this doesn't work it's always a good idea to throw some debug messages in to test the script.

log.debug "Parent ID: ${parentTaskID}"

It works like a charm! Thank you very much!

Yes, issue id is always valid. I use database child custom field to retrieve it and make it read only. Also validating it against beeing "null".

Useful answer, thanks!
