on 10.11 notifications set to fire from the Issue Resolved event fail to pick up the comment added by the close issue window and therefore no email with the resolution is being sent out to our customers. These worked fine before that time.
We are using a very basic setup of the JETI handler at the moment and are almost entirely copying the step by step Email Helpdesk as is shown in your wiki.
I have checked for other events sending out notifications (set the notifications to fire on issue comment edited or comment added and these work fine.)
What i have noticed is that no change, status, resolution or comment, made in the resolve issue screen is able to generate an event. Have you encountered this bug?
