Simple Scripted Validator - Assignee is unassigned at time of transition

[Bus Van Wagoner]

I would like to create a Transition Validator using the Simple Scripted Validator to check the Assignee field is blank or unassigned at the time of transition. It seems logical to me I could take the example provided "Assignee changed (Workflow functions only)"

issue.assignee != originalIssue.assignee

And change it to:

issue.assignee == NULL

But I get an error about NULL being an undeclared variable. 

Is there a simple 1 or 2 line way to do this?

I have other fields I would also like to verify the values of or verify they have or don't have a value when transitioning an issue. Would it be different for other types of fields?

Hello, 

You should be able to do something like this in a simple scripted validator:

if(!issue.assignee){ return false }

Let me know if that works for you!

Jenna, this one worked for me, thanks!

issue.assignee == null did not work for some reason, but I'll quit fretting since yours did.

Actually none of these worked for me. Below one worked:

issue.assigneeId != null || false

The previous answers are technically correct for the version of Jira at the time.  I have found that this is the correct solution for the Jira 8.x product.

Have you tried issue.assignee == null ?

[Bus Van Wagoner]

That worked!

Now I feel stupid.

Thanks for your help.

Hi,

Can you please help me create a groovy script:

If Assignee field was changed from "Unassigned"

then

move an issue to "status name"

I'm trying to use "Fast-track transition an issue"

Events: Issue Assigned

Condition: I'm not sure 

Action: "status name"

issue.assignee == null is not working for me

issue.assignee != originalIssue.assignee - is working for me however it's working also if I change assignee from "someone" to "Unassigned" 

Thank you
