Workflow post function to copy custom field to assignee

[flaimo]

I want to use a custom script as a scriptrunner transition post function to set the assignee based on the value of a custom user field ("Implemented by"):

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.util.ImportUtils
import com.atlassian.jira.user.util.UserManager
import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.user.ApplicationUser

def userUtil                          = ComponentAccessor.getUserUtil();
UserManager userManager               = ComponentAccessor.getUserManager()

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
CustomField cfImplementedByField      = customFieldManager.getCustomFieldObject('customfield_11142')
def cfImplementedByValue              = issue.getCustomFieldValue(cfImplementedByField)
ApplicationUser implementedBy         = userManager.getUserByName(cfImplementedByValue?.displayName)

if (implementedBy != "" && implementedBy != null) {
    issue.setAssignee(implementedBy)
}

I get the following error:

How to I get to recognize the script, that the custom field value is a user?

Hi Flamio,

I have attached a sample script which take the value from a custom user picker such as one called Implemented By and set it to the Assignee field during a transition.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.user.ApplicationUser

// Get required Managers
def customFieldManager = ComponentAccessor.getCustomFieldManager()

// get a pointer to the Implemented By user picker field and its value
def userCf = customFieldManager.getCustomFieldObjectByName("Implemented By")
def implUser = issue.getCustomFieldValue(userCf) as ApplicationUser

// If the Implemented By Field is not null then set the assignee
if(implUser){
	issue.setAssigneeId(implUser.username.toString())
}

I hope this helps.

Thanks

Kristian

Hello,

I'm using your code defined as an additional action on the "Clones an issue and links" built-in script (Scriptrunner for JIRA), as can be seen in below screenshot:

In the main Story we are defining the "8-LP-Assignee" User Picker field during one of the transitions. The above mentioned script is being defined as a Post-Function in this same transition, which is cloning the issue into another project.

Result is the following:

- For some users, the assignee of the cloned issue has been set correctly towards the person defined earlier in the "8-LP-Assignee" field.

- For other users, the value of the assignee field is being showed as the username in the View issue screen, as e.g. below:

Problem is that the user has not been set correctly as no hyperlink is shown towards the user in the Search Issue screen:

When I click on the assignee field and directly click on enter, the real person is getting defined, as apparently now JIRA is going to lookup the correct person with as a result that the real name is being shown instead of the username:

By using the Script Console, you can see what JIRA is defining in the issue.assignee field, BEFORE and AFTER selecting the assignee field manually and clicking on enter as explained above:

BEFORE:

AFTER:

Remark the difference of capital and small letters as username between the brackets.

Can anyone help me out here in order to solve this problem?

Thanks a lot.

I'm having difficulty with the same issue... I can't get the script suggested above to work, though maybe there is some deprecated code? There are no errors in ScriptRunner, it just isn't working properly.

I am having the same experience. No error, just unassigned sub-tasks. Any resolution yet?

[Cinnober Admins]

No idea what issue I had before (I don't remember), but it looks like I went with something following the pattern of the example code above. 

Could have been that the post-function was placed before "Creates the issue originally." or something.

Thank you, your solution works. There is some strange effect on a Kanban board though. When a user drag&drops an issue into a column, which triggers the transition with the post function script, the assignee is set, but the user avatar is not displayed on the board. Even a refresh doesn't help. Do I need to trigger some sort of manual refresh here somehow?

Hi Flamio,

I have looked at this and noticed the line in the if should be changed to issue.setAssigneeId(implUser.username.toString()) as the setAssigneeId method expects the username of the user.

I have updated the example code above. This new code should set the avatar on the Kanban board.

I hope this helps.

Thanks

That did it. Thank you very much!
