Post-function script Jira

Alexander_udh0is

Good day!
Sorry for my bad English)
I wrote the script in post-function, but he is not work.
We need to change the custom field to the value of the system field, and if the custom field is already filled, then put its value in the system. I hope I have expressed clearly
Script:
import com.atlassian.jira.component.ComponentAccessor
def bf = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Исполнитель")
def br = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Технолог");
if(br) {
return issue.getCustomFieldValue(bf)
} else{
ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Исполнитель")
return issue.getCustomFieldValue(br)
}

Error:

2018-09-19 12:17:55,896 ERROR [workflow.ScriptWorkflowFunction]: *************************************************************************************
2018-09-19 12:17:55,897 ERROR [workflow.ScriptWorkflowFunction]: Script function failed on issue: PB-420, actionId: 331, file: <inline script>

Please help me fix the script...
Thank you in advance!

Hello @Alexander,

Can you try the code below. Let me know the result.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder

Issue issue = issue
CustomField customfield_a = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("cf id with value A")
CustomField customfield_b = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("cf id with value B")

def value_a = customfield_a.getValue(issue)
def value_b = customfield_b.getValue(issue)

if(value_a == null ||value_a == ""){
    customfield_a.updateValue(null, issue, new ModifiedValue(null, value_b), new DefaultIssueChangeHolder())
}else{
    customfield_b.updateValue(null, issue, new ModifiedValue(null, value_a), new DefaultIssueChangeHolder())
}

Hello @Alexander,

Hello!
There is a field with the value " A"
There is a field with a value of " B"
So I need, if the field with the value "A" is empty, then assign it the value "B". And if the field with the value " A "is already filled, assign this value to the field with the value"B".

I guess customfield B is null in your case. Make sure you are writing customfield id correctly. For intance, "customfield_1234". Can you please copy the following code again and share the logs again with the logs I added.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import org.apache.log4j.Logger

Logger log = Logger.getLogger("Atlassian Community")

Issue issue = issue
CustomField customfield_a = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("cf id with value A")
CustomField customfield_b = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("cf id with value B")

log.warn("Issue : " + issue)
log.warn("cf A : " + customfield_a)
log.warn("cf B : " + customfield_b)

def value_a = customfield_a.getValue(issue)
def value_b = customfield_b.getValue(issue)

log.warn("Value A : " + value_a)
log.warn("Value B : " + value_b)

if(value_a == null ||value_a == ""){
    customfield_a.updateValue(null, issue, new ModifiedValue(null, value_b), new DefaultIssueChangeHolder())
}else{
    customfield_b.updateValue(null, issue, new ModifiedValue(null, value_a), new DefaultIssueChangeHolder())
}
