Pre-populate the assignee field on a transition in JIRA

Sneha Sheth

I have a certain user which need to be pre-populated on fixed transitions in the assignee field. I tried using the behaviours plugin and the following code but it is not working. Neither it is giving any error in the logs.

 

FormField assi = getFieldById("assignee")

assi.setFormValue("username");

 

What am I doing wrong here?

Which field did you put that behaviour on? Versions please?
