Thanks for the feedback.
Maybe _I_ am missing something obvious, but I'm not dealing with a regular cms
template, but rather a TemplatedMVCHandler template which will be used in the
AdminCentral (called something like /.magnolia/pages/myAdminPage). Or does what
you describe also apply to "pages" when configured correctly?
And... no, I don't need the current user. The goal would be to get a custom
user management page.
