Copying value assignee field in custom field

[Alexander]

Hi!
I try run this script:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.user.ApplicationUser

MutableIssue issue
Issue issueIM  = issue   
CustomField technolog = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("name customfield")

def value_a = technolog.getValue(issue)
def assignee = issue.getAssigneeId()

if(value_a == null ||value_a == ""){
    technolog.updateValue(null, issue, new ModifiedValue(null, assignee), new DefaultIssueChangeHolder())
}
else {
 issue.setAssignee((ApplicationUser)value_a)
}

We need the assignee field value to be copied to the custom field in case the custom field is empty.
But script don't work.

Hello @Alexander

This is not right in your code

def value_a = technolog.getValue(issue)

To get the customfield value you should use issue.getCustomFieldValue 

def value_a = issue.getCustomFieldValue(technolog)

Also, to update issues you should always use IssueService

Hi @Tarun Sapra
Thanks for your reply
If a custom field has a value, the Assignee field accepts it.
However, the Assignee field does not take a custom field value.
I guess error in this line:
 technolog.updateValue(null, issue, new ModifiedValue(null, assignee), new DefaultIssueChangeHolder())
Error log:
java.lang.ClassCastException: java.lang.String cannot be cast to com.atlassian.jira.user.ApplicationUser at com.atlassian.jira.issue.customfields.impl.UserCFType.getDbValueFromObject(UserCFType.java:83) at com.atlassian.jira.issue.customfields.impl.AbstractSingleFieldType.createValue(AbstractSingleFieldType.java:138) at com.atlassian.jira.issue.fields.ImmutableCustomField.createValue(ImmutableCustomField.java:693) at com.atlassian.jira.issue.fields.ImmutableCustomField.updateValue(ImmutableCustomField.java:410) at com.atlassian.jira.issue.fields.ImmutableCustomField.updateValue(ImmutableCustomField.java:396) at com.atlassian.jira.issue.fields.OrderableField$updateValue.call(Unknown Source) at Script1176.run(Script1176.groovy:20)

Sorry, I'm new to this.

Hello @Alexander

What's the type of the field "technolog" in jira, is it text or single select etc

[Alexander]

Type is "User Picker (single user)"

[Tarun Sapra]

Then you should save the ApplicationUser object instead of string in the custom field updateValue.

[Alexander]

I want it:
Copy the user from the Assignee field to the custom field "technolog"  (replacing value).
This method does not work :
 technolog.updateValue(null, issue, new ModifiedValue(null, assignee), new DefaultIssueChangeHolder())
Help edit please...

[Alexander]

"Then you should save the ApplicationUser object instead of string in the custom field updateValue."- Yes, it's right!

[Tarun Sapra]

Glad to know @Alexander that it works, please accept/upvote the answer so that others are helped as well. 

[Alexander]

You did not understand me. The value of the assignee field is not copied to the custom field (technology).
I need to fix this.

[Tarun Sapra]

Yes, & as I have already told you, please create an ApplicationUser object from the assignee.

[Alexander]

Can you give an example script?

[Tarun Sapra]

Hello @Alexander

Along with the changes which I have shared already, just change your code from

 def assignee = issue.getAssigneeId()

to

 def assignee = issue.getAssignee() 

And it should work
