Prevent transition when issue unassigned

[Steve Sweales]

Is it possible within a workflow (I would have thought via a condition) to prevent a transition if the issue is unassigned?

Yes, as you say, with a condition.

Hi Nic, how would you do this with a condition?

Figured it out.

I can use a Script Condition (issue.assignee == null) on the transition. Does the job nicely. :-)

how do I add a script condition ?

workflow > click on transition > conditions > add condition ?
