How to display the actor in JIRA notifications

[Robert Eichenberger]

VM context value "changelogauthor" cannot be used in email subject templates. Does anyone know what values are provided when running the template for email subjects?

I found it in
https://developer.atlassian.com/display/JIRADEV/Velocity%20Context%20for%20Email%20Templates

More information:

We were receiving emails like:
"[JIRA] Commented: (ABC-391) BlaBlaBla"
from JIRA.
I wanted to change the subjects to include the author, such as:
"[JIRA] Jack Brown Commented: (ABC-391) BlaBlaBla"

So, I tried using the context value "changelogauthor", but it seems it doesn't exist when subject is processed by Velocity.
Instead I got this:
"[JIRA] $changelogauthor.name Commented: (ABC-391) BlaBlaBla"

I changed the template: "$eventTypeName: ($issue.key) $issue.summary" to "$changelogauthor.name $eventTypeName: ($issue.key) $issue.summary".

It is not clear what context values exist for rendering subjects in

Try this << Untested >>

#if ($commentauthor) $commentauthor.name #else $remoteUser.name #end $eventTypeName: ($issue.key) $issue.summary"
