Multiple bibiographies using biblatex, and resetting numbers

Multiple bibiographies using biblatex, and resetting numbers

I am writing a sort of large CV, and I've split my publications into
several blocks, using this:
\nocite{*}
\printbibheading[title={Publications}]
\printbibliography[nottype=online,heading=subbibliography,
title={Printed Sources},resetnumbers=true]
\printbibliography[type=online,heading=subbibliography,
title={Online Sources},resetnumbers=true]
which I mostly copied from the biblatex manual. However, the numbers
aren't being reset as I want. The numbers in the Online Sources part, for
example, go [13], [21], [29], [36] instead of [1], [2], [3], [4] as I'd
like them to.
Probably there are options better suited to my purpose than resetnumbers,
but I haven't found them yet. Basically I want each sub-bibliography to be
numbered starting at [1], and increasing in increments of 1. Ideas or
advice?
