Getting user principal attributes in header.vm

Hi All

I am setting up some new themes for our applications, which means creating new files for header.vm and footer.vm. Unfortunately I am not a Velocity expert :)

I would like to put something like "Logged in as jsmith: Joe Smith" in the header.  The jsmith loginId is easy (principal.getName()), but I can't seem to pull the user.name.family and user.name.given attributes from the attributes map structure - either I get an empty string, or the line of velocity code appears verbatim. The attributes are present, as I can access them from portlet Java code.

Can some Velocity guru point me in the right direction?

Regards

Ron
