How can I generate a UUID and assign to a custom field?

[Aswini Vayyala]

Hi,

I need to generate UUID and assign it to a custom field using a post function script when an issue is opened?

Has anyone done this before?

Thanks

Ashwini

Please try not to cross-post. We need to respond on all channels otherwise it looks like we don't care, which takes us a lot of additional time, and dilutes the value for other people using it.

To repeat:

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def cf = customFieldManager.getCustomFieldObjectByName("My Field")
issue.setCustomFieldValue(cf, UUID.randomUUID().toString())
