get "userName" / "userkey" from custom field with "userdisplayName"


we want to assign an issue to a user from a custom field (From anpother plugin (CRM). The field only displays the full display name) using the behaviours/scriptrunner plugin.

see image:  (Attaching images here was not possible?! -> Server Error)

I think we need to get the "userName" / "userkey" (e.g.: FF) from the custom field with the "userdisplayName" (e.g.: Fred Flintstone) to set the Assignee afterwards.

I hope someone could help.


Or is the "Issue Alternative Assignee"-Plugin capable of that? (we have Jira V7.1.1)


kind regards

yes this "findUserNames" seems to be what we need - but we are too unskilled to implement this in our behaviour.

Can you (or someone else)  please give us an example what classes we have to import and how the syntax should be (we are no programmers) ?

This is the (not working) serverside script we have right now:

import static com.atlassian.jira.issue.IssueFieldConstants.*
import com.atlassian.jira.user.ApplicationUsers
//Line below does not work

//Line below is for testing only

thx in advance

Could you add your supplementary questions as comments rather than as answers? 

I think you are looking for an example of how to look up a user by display name, so here is one (I don't know what the code above is supposed to do):

import com.atlassian.jira.component.ComponentAccessor

def userSearchService = ComponentAccessor.getComponent(UserSearchService)
def users = userSearchService.findUsersByFullName("Mr Admin")

if (users) {
    users.first() // an ApplicationUser (in jira 7)
else {
    // no users found with that display name

oh sorry, will do next time/s.

this is exactly what we need =) An example.

Thank you & kind regards


Hello @JamieA ,

Could you please help me fetch a username from a String which is actually the Full Name/Display name of the user?

@JamieA : 

Nevermind. I tried the above script and it worked for me. Thank you

I don't know anything about that plugin, but most likely it will give you an ApplicationUser object if you call issue.getCustomFieldValue on that CF. That would be the way to go rather than trying to look up a key by display name. 

Hello Jamie,

thanks for your answer. We already did that, but the field only returns a string (equal to the full display username). So we need somehow to get the user behind that string.

When we write the value in a comment field with:


we get

Form field ID: customfield_12239, value: Fred Flintstone

When we try to put this value in the assigne field its not working.
