Script Runner set date field based on custom field

[Kevin Dalton]

Trying to set the value for a field based on another field so the value is retained as the original value.

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
import java.sql.Timestamp
import org.joda.time.DateTime;
import org.apache.commons.lang.time.DateUtils;
import java.text.SimpleDateFormat;
import java.util.Date.*;

Issue issue = issue
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-YYYY");
def ocf = customFieldManager.getCustomFieldObjectByName("Expected Delivery Date")
def strDate = sdf.format(ocf).format("dd-MM-YYYY")
def cf = customFieldManager.getCustomFieldObjectByName("Original Delivery Date")

if (!cf)

issue.setCustomFieldValue(cf, strDate)

Error:

If both custom fields are date type then you could use this code:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();

issue.setCustomFieldValue(
        customFieldManager.getCustomFieldObjectByName("Expected Delivery Date")
        , customFieldManager.getCustomFieldObjectByName("Original Delivery Date"))

If not, say types of these custom fields.

Both custom fields are date fields and I am trying to have a scripted field set the original date only when the expected date is entered the 1st time.  If the expected date is changed we want the original to stay with what the 1st value was.

You should not use a script field to make any changes for the issue - it should only read information and display a calculated value.

You have different options here - 

1. Use a script field to display the first field value from the change history of the issue
2. Use a listener to copy the current value to a standard date field, only if there is no previous values for it.

[Vasiliy Zverev]

Lets start with:

1. expected date is changed - how this date is changed: via transition, then postfunction could be used, or via issue edit - then you need isue listener
2. Script field - is a custom filed which value is calculated by script. Is your fields are date type or scripted fields?

Looks like you are trying to set a Date CF to a String... set it to a Date. Vasiliy's code looks valid.
