Create issue post function not able to change issue fields

Jordan Paul_smfbta

I am trying to create a post-function in a "create issue" transition, and it is not working as expected. I am trying to use field values provided by users on the "create issue" screen to automatically set field values of the issue itself. However, my post function has no effect. I have read that the order of events in which the post function takes place matters, and I have tried moving the post function to all combinations of before and after the "Creates the issue originally" and "Re-index an issue to keep indexes in sync with the database." stages.

In some positions, I am able to access the user-provided field values but can't change them. In other positions, I am able to change the fields but I can't access the user-provided values. There does not appear to be a solution/location where I am able to *both* read the user-provided values *and* change them according to the script.

I have read the documentation about post-functions, for example this page:
https://docs.adaptavist.com/sr4js/latest/features/workflows/post-functions/custom-post-functions/custom-post-function-examples/set-issue-attributes

On this page, it mentions the importance of running your post-function "before the standard function" and if that doesn't work you need to "use a more complex method." But I am unable to find any information on this "more complex method"

Any assistance is appreciated (including pointing me in the direction of where I can learn more about this "more complex method")

 

import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Logger
import org.apache.log4j.Level
import java.util.regex.*;

log.setLevel(Level.DEBUG)

def components = ComponentAccessor.projectComponentManager.findComponentsByIssue(issue)
log.info(components)
if(components != null){
    def count = 0

    //Get the list of component provided during the create screen
    //Test look up their descriptions to see if they match some condition
    def pattern = Pattern.compile("some-regex-here", Pattern.CASE_INSENSITIVE)
    for(def component in components){
        def compDesc = component.getDescription()
        log.info(compDesc)
        if(!compDesc) continue;
        if(pattern.matcher(compDesc).find()){
            count++
        }
    }
    log.info("Match Count: " + count)

    //Set a custom user field if the above component check matches
    def cf = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_10400")
    if(count > 0){
        log.info("Component match")
        def user = ComponentAccessor.getUserManager().getUserByKey("myUser")
        issue.setCustomFieldValue(cf, user)
    }
}

Hi @Jordan Paul ,

probelm is that you are not updating your issue.

At the end of your code (when you set the custom field value), you should use the following method https://docs.atlassian.com/software/jira/docs/api/8.2.0/com/atlassian/jira/issue/IssueManager.html#updateIssue-com.atlassian.jira.user.ApplicationUser-com.atlassian.jira.issue.MutableIssue-com.atlassian.jira.event.type.EventDispatchOption-boolean-

... 
 IssueManager issueManager = ComponentAccesso.getIssueManager();
 ApplicationUser loggedInUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

....

  if(count > 0){
        log.info("Component match")
        def user = ComponentAccessor.getUserManager().getUserByKey("myUser")
        MutableIssue mIssue = (MutableIssue)issue;
        mIssue.setCustomFieldValue(cf, user);
        issueManager.updateIssue(loggedInUser,mIssue,EventDispatchOption.DO_NOT_DISPATCH, false)
    }

Above an example of missing code.

Hope this helps,

Fabio
