How to copy a date custom field from parent to sub-task using groovy script?

[Vishali]

I have a date custom field whose value should be copied over from parent to its sub-task using groovy script. Is there any reference that I can take a look?

few steps:

1) get the customfield id (you can check by going to the fields -> click on the custom field), the id is part of the URL (at least in JIRA 4.4)

2) For the code:

a) find the parent ticket (newIssue)

b) find the value by

def requestorFieldName = "customfield_XXXXX"

ComponentManager componentManager = ComponentManager.getInstance()   
CustomFieldManager customFieldManager = componentManager.getCustomFieldManager()

//get Requestor Name
CustomField field = customFieldManager.getCustomFieldObject(fieldName)
requestorName = newissue.getCustomFieldValue(field)

c) and you can set the current issue with issue.setCustomFiedl (I think - best to look for JIRA API documentation)

Again this is based off JIRA 4.4, so you might need to double check the API documentation for whichever version you are using

Hope this helps!

Eva,

One of the date custom fields is causing a null pointer exception.

can you paste the code here? It's hard to troubleshoot without seeing the full code...?

Do you have a clue on what this error is about?

Thanks,
