Tracking due date history in a text field using behaviors in Scriptrunner

[Cory Strope]

I am trying to capture the history of due dates in a custom text field, 'Deadline Extension History'. I have set up a ScriptRunner (v 6.24.0) behavior to make the change each time the due date is changed by a user.

----

import java.text.SimpleDateFormat

SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");

def DEH = getFieldByName("Deadline Extension History")
def dueDateField = getFieldById(getFieldChanged()) // Due date has changed
def dueDate = dueDateField.getValue() as Date

// Get the current value of the Deadline Extension History
def selectedOption = DEH.getValue() as String
def valueSet = selectedOption + '\n' + sdf.format(dueDate)
DEH.setFormValue(valueSet)

----

When I make a change to the date, instead of concatenating a single date to the Deadline Extension History it adds several dates:

Expected:
2021/05/10
2021/05/17

Actual:
2021/05/10
2021/05/10
2021/05/10
2021/05/17
2021/05/17

When I modiry the valueSet to either 'selectedOption' or to 'sdf.format(dueDate)', the Deadline Extension History will take on only the value of selectedOption or sdf.format(dueDate), respectively.

Is there a there a better way to set up the behavior to get the expected value? I am able to make this happen on transition, but would prefer to avoid that path.

Hello @Cory Strope 

Rather than storing every single change in a text field, it would be better to use a read-only/calculated custom field which will directly provide historical dates for duedate field. 

Let me try with a code snippet below. dueDateChanges variable will hold every date values

import com.atlassian.jira.component.ComponentAccessor

def changeHistoryManager = ComponentAccessor.changeHistoryManager
def issueManager = ComponentAccessor.getIssueManager()

def dueDateChanges = []
changeHistoryManager.getChangeItemsForField (issue, "duedate").each { 
   if (null != it.from) dueDateChanges.add(it.from)
}
if (null != issue.dueDate) dueDateChanges.add (issue.dueDate)

If dueDate changed it will add the "from value" of the change item, then it adds the current value at the end.

You might do the correct date conversions but this code will do your trick after changing a couple of lines for your needs.

I hope it helps

After returning the array, it worked perfect.

Thanks!

Perfect! I'm glad that it worked.

Hi @Cory Strope 

Can you share your code in behaviour? I'm working the same approach. Thanks!
