Forum OpenACS Q&A: Categories 1.0d3 error

I'm not sure if i need a new version of acs-templating (currently 5.0.4), but template::multirow is calling sort, but it's not an actual command from the api.

The error I get from http://server/categories/cadmin/object-map?object%5fid=XXXX:

Unknown command sort in template::multirow.
      Must be create, extend, append, backup, get, set, size, upvar, or foreach.
    while executing
