Using variables from currently logged in user in Email Client Template

[roy_walton]

I've created an Email Client Template to be used from within CSM, to include an autosignature. As it is now, the autosignature includes variables for the current case (task) from our Investor Relations table. For example:

${assigned_to.first_name} ${assigned_to.last_name}
${assigned_to.u_functionaltitle}
My Company | ${assigned_to.location.city}, ${assigned_to.location.state}
T: +${assigned_to.phone}
${assigned_to.email}

Is there a way to include variables for the currently logged in user, rather than the assigned to person for the case? They wouldn't necessarily be the same person. We've tried a couple of things that didn't work:

${gs.getUser().first_name} etc.

<mail_script>

template.print( gs.getUser().getFullName() );
</mail_script>

Note that this is an Email Client Template (in the sys_email_client_template table) not a Response Template or system notification email template.

Old post, but providing answer for anyone else that come after.

Use ${current_user}

Additionally, this can be used to get attributes from the user record.  However, it cannot dot-walk to reference tables.

Will Work

${current_user.location}

Will NOT work

${current_user.location.city}
