Changing a field value with scriptrunner depending on an other field value

[fr Behnk]

Hi,

I would like to write a script with scriptrunner that updates a field depending on an other field.

Field A (Textfield)

Field B (Textfield)

The user changes Field A. Then Field B gets an other value.

• Does anyone have a clue, where shall I write the script in Scriptrunner (Built-in Scripts, Listeners, ...)
• Can anyone provides a snippet?

Thanks in advance.

Best

Friedrich

Hi @fr Behnk it depends when you want to do this update. If it is in a transition you only have to write a new postfunction script. 

If you want to do it whenever the field is updated you should write a new listener. You have to have in mind that the update only work when and issue is updated. If the field is changed in a field screen, the listener wouldnt work unless you add the event that is fired in that specific transition.

For the postfunction script (this way you can use it even in the create transition. Add it between the update postfunction and the reindex postfunction places):

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

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()

CustomField cfTextFieldA = customFieldManager.getCustomFieldObject(11111L), //Change the ID with the TextFieldA ID
            cfTextFieldB = customFieldManager.getCustomFieldObject(22222L) //Change the ID with the TextFieldB ID

cfTextFieldB.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(cfTextFieldB), issue.getCustomFieldValue(cfTextFieldA)), new DefaultIssueChangeHolder())

 For the listener:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.issue.IssueEvent
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.changehistory.ChangeHistoryItem
import com.atlassian.jira.issue.changehistory.ChangeHistoryManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.index.IssueIndexingService
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import org.ofbiz.core.entity.GenericValue

IssueEvent event = event as IssueEvent
MutableIssue issue = event.issue

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
ChangeHistoryManager changeHistoryManager = ComponentAccessor.getChangeHistoryManager()

CustomField cfTextFieldA = customFieldManager.getCustomFieldObject(11111L), //Change the ID with the TextFieldA ID
            cfTextFieldB = customFieldManager.getCustomFieldObject(22222L) //Change the ID with the TextFieldB ID

GenericValue changeLogs = event.getChangeLog()
ArrayList<ChangeHistoryItem> changedItem = changeHistoryManager.getAllChangeItems(issue).findAll {
    it.changeGroupId == changeLogs.id
}

if (changedItem?.find { it.field.equalsIgnoreCase(cfTextFieldA.name) }) {
    cfTextFieldB.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(cfTextFieldB), issue.getCustomFieldValue(cfTextFieldA)), new DefaultIssueChangeHolder())
    ComponentAccessor.getComponent(IssueIndexingService).reIndex(issue)
}

 Hope it helps.

Hi @fr Behnk,

You should write it as listener.

Because you want to listen to "issue updated".

Any time an issue has been updated, you want to check field A and update B accordingly.
